# Scientific Slides
|
||||
|
||||
## Overview
|
||||
|
||||
Scientific presentations are a critical medium for communicating research, sharing findings, and engaging with academic and professional audiences. This skill provides comprehensive guidance for creating effective scientific presentations, from structure and content development to visual design and delivery preparation.
|
||||
|
||||
**Key Focus**: Oral presentations for conferences, seminars, defenses, and professional talks.
|
||||
|
||||
**CRITICAL DESIGN PHILOSOPHY**: Scientific presentations should be VISUALLY ENGAGING and RESEARCH-BACKED. Avoid dry, text-heavy slides at all costs. Great scientific presentations combine:
|
||||
- **Compelling visuals**: High-quality figures, images, diagrams (not just bullet points)
|
||||
- **Research context**: Proper citations from research-lookup establishing credibility
|
||||
- **Minimal text**: Bullet points as prompts, YOU provide the explanation verbally
|
||||
- **Professional design**: Modern color schemes, strong visual hierarchy, generous white space
|
||||
- **Story-driven**: Clear narrative arc, not just data dumps
|
||||
|
||||
**Remember**: Boring presentations = forgotten science. Make your slides visually memorable while maintaining scientific rigor through proper citations.
|
||||
|
||||
## When to Use This Skill
|
||||
|
||||
This skill should be used when:
|
||||
- Preparing conference presentations (5-20 minutes)
|
||||
- Developing academic seminars (45-60 minutes)
|
||||
- Creating thesis or dissertation defense presentations
|
||||
- Designing grant pitch presentations
|
||||
- Preparing journal club presentations
|
||||
- Giving research talks at institutions or companies
|
||||
- Teaching or tutorial presentations on scientific topics
|
||||
|
||||
## Visual Enhancement with Scientific Schematics
|
||||
|
||||
**When creating documents with this skill, always consider adding scientific diagrams and schematics to enhance visual communication.**
|
||||
|
||||
If your document does not already contain schematics or diagrams:
|
||||
- Use the **scientific-schematics** skill to generate AI-powered publication-quality diagrams
|
||||
- Simply describe your desired diagram in natural language
|
||||
- Nano Banana Pro will automatically generate, review, and refine the schematic
|
||||
|
||||
**For new documents:** Scientific schematics should be generated by default to visually represent key concepts, workflows, architectures, or relationships described in the text.
|
||||
|
||||
**How to generate schematics:**
|
||||
```bash
|
||||
python scripts/generate_schematic.py "your diagram description" -o figures/output.png
|
||||
```
|
||||
|
||||
The AI will automatically:
|
||||
- Create publication-quality images with proper formatting
|
||||
- Review and refine through multiple iterations
|
||||
- Ensure accessibility (colorblind-friendly, high contrast)
|
||||
- Save outputs in the figures/ directory
|
||||
|
||||
**When to add schematics:**
|
||||
- Research methodology workflow diagrams for slides
|
||||
- Conceptual framework illustrations
|
||||
- Experimental design visualizations
|
||||
- Data analysis pipeline diagrams
|
||||
- System architecture diagrams
|
||||
- Biological pathway or mechanism diagrams
|
||||
- Timeline and milestone visualizations
|
||||
- Any complex concept that benefits from visualization
|
||||
|
||||
For detailed guidance on creating schematics, refer to the scientific-schematics skill documentation.

## Core Capabilities
|
||||
|
||||
### 1. Presentation Structure and Organization
|
||||
|
||||
Build presentations with clear narrative flow and appropriate structure for different contexts. For detailed guidance, refer to `references/presentation_structure.md`.
|
||||
|
||||
**Universal Story Arc**:
|
||||
1. **Hook**: Grab attention (30-60 seconds)
|
||||
2. **Context**: Establish importance (5-10% of talk)
|
||||
3. **Problem/Gap**: Identify what's unknown (5-10% of talk)
|
||||
4. **Approach**: Explain your solution (15-25% of talk)
|
||||
5. **Results**: Present key findings (40-50% of talk)
|
||||
6. **Implications**: Discuss meaning (15-20% of talk)
|
||||
7. **Closure**: Memorable conclusion (1-2 minutes)
|
||||
|
||||
**Talk-Specific Structures**:
|
||||
- **Conference talks (15 min)**: Focused on 1-2 key findings, minimal methods
|
||||
- **Academic seminars (45 min)**: Comprehensive coverage, detailed methods, multiple studies
|
||||
- **Thesis defenses (60 min)**: Complete dissertation overview, all studies covered
|
||||
- **Grant pitches (15 min)**: Emphasis on significance, feasibility, and impact
|
||||
- **Journal clubs (30 min)**: Critical analysis of published work
|
||||
|
||||
### 2. Slide Design Principles
|
||||
|
||||
Create professional, readable, and accessible slides that enhance understanding. For complete design guidelines, refer to `references/slide_design_principles.md`.
|
||||
|
||||
**ANTI-PATTERN: Avoid Dry, Text-Heavy Presentations**
|
||||
|
||||
❌ **What Makes Presentations Dry and Forgettable:**
|
||||
- Walls of text (more than 6 bullets per slide)
|
||||
- Small fonts (<24pt body text)
|
||||
- Black text on white background only (no visual interest)
|
||||
- No images or graphics (bullet points only)
|
||||
- Generic templates with no customization
|
||||
- Dense, paragraph-like bullet points
|
||||
- Missing research context (no citations)
|
||||
- All slides look the same (repetitive)
|
||||
|
||||
✅ **What Makes Presentations Engaging and Memorable:**
|
||||
- HIGH-QUALITY VISUALS dominate (figures, photos, diagrams, icons)
|
||||
- Large, clear text as accent (not the main content)
|
||||
- Modern, purposeful color schemes (not default themes)
|
||||
- Generous white space (slides breathe)
|
||||
- Research-backed context (proper citations from research-lookup)
|
||||
- Variety in slide layouts (not all bullet lists)
|
||||
- Story-driven flow with visual anchors
|
||||
- Professional, polished appearance
|
||||
|
||||
**Core Design Principles**:
|
||||
|
||||
**Visual-First Approach** (CRITICAL):
|
||||
- Start with visuals (figures, images, diagrams), add text as support
|
||||
- Every slide should have STRONG visual element (figure, chart, photo, diagram)
|
||||
- Text explains or complements visuals, not replaces them
|
||||
- Think: "How can I show this, not just tell it?"
|
||||
- Target: 60-70% visual content, 30-40% text
|
||||
|
||||
**Simplicity with Impact**:
|
||||
- One main idea per slide
|
||||
- MINIMAL text (3-4 bullets, 4-6 words each preferred)
|
||||
- Generous white space (40-50% of slide)
|
||||
- Clear visual focus
|
||||
- Bold, confident design choices
|
||||
|
||||
**Typography for Engagement**:
|
||||
- Sans-serif fonts (Arial, Calibri, Helvetica)
|
||||
- LARGE fonts: 24-28pt for body text (not minimum 18pt)
|
||||
- 36-44pt for slide titles (make bold)
|
||||
- High contrast (minimum 4.5:1, prefer 7:1)
|
||||
- Use size for hierarchy, not just weight
|
||||
|
||||
**Color for Impact**:
|
||||
- MODERN color palettes (not default blue/gray)
|
||||
- Consider your topic: biotech? vibrant colors. Physics? sleek darks. Health? warm tones.
|
||||
- Limited palette (3-5 colors total)
|
||||
- High contrast combinations
|
||||
- Color-blind safe (avoid red-green combinations)
|
||||
- Use color purposefully (not decoration)
|
||||
|
||||
**Layout for Visual Interest**:
|
||||
- Vary layouts (not all bullet lists)
|
||||
- Use two-column layouts (text + figure)
|
||||
- Full-slide figures for key results
|
||||
- Asymmetric compositions (more interesting than centered)
|
||||
- Rule of thirds for focal points
|
||||
- Consistent but not repetitive
|
||||
|
||||
### 3. Data Visualization for Slides
|
||||
|
||||
Adapt scientific figures for presentation context. For detailed guidance, refer to `references/data_visualization_slides.md`.
|
||||
|
||||
**Key Differences from Journal Figures**:
|
||||
- Simplify, don't replicate
|
||||
- Larger fonts (18-24pt minimum)
|
||||
- Fewer panels (split across slides)
|
||||
- Direct labeling (not legends)
|
||||
- Emphasis through color and size
|
||||
- Progressive disclosure for complex data
|
||||
|
||||
**Visualization Best Practices**:
|
||||
- **Bar charts**: Comparing discrete categories
|
||||
- **Line graphs**: Trends and trajectories
|
||||
- **Scatter plots**: Relationships and correlations
|
||||
- **Heatmaps**: Matrix data and patterns
|
||||
- **Network diagrams**: Relationships and connections
|
||||
|
||||
**Common Mistakes to Avoid**:
|
||||
- Tiny fonts (<18pt)
|
||||
- Too many panels on one slide
|
||||
- Complex legends
|
||||
- Insufficient contrast
|
||||
- Cluttered layouts
|
||||
|
||||
### 4. Talk-Specific Guidance

|
||||
|
||||
**Visual Validation Workflow**:
|
||||
|
||||
**Step 1: Generate PDF** (if not already PDF)
|
||||
- PowerPoint: Export as PDF
|
||||
- Beamer: Compile LaTeX source
|
||||
|
||||
**Step 2: Convert to Images**
|

||||
python scripts/pdf_to_images.py presentation.pdf review/slide --dpi 150
|
||||
|
||||
# Or use pptx skill's thumbnail tool
|
||||
python ../document-skills/pptx/scripts/thumbnail.py presentation.pptx review/thumb
|
||||
```
|
||||
|
||||
**Step 3: Systematic Inspection**
|
||||
|
||||
Check each slide for:
|
||||
- **Text overflow**: Text cut off at edges
|
||||
- **Element overlap**: Text overlapping images or other text
|
||||
- **Font sizes**: Text too small (<18pt)
|
||||
- **Contrast**: Insufficient contrast between text and background
|
||||
- **Layout issues**: Misalignment, poor spacing
|
||||
- **Visual quality**: Pixelated images, poor rendering
|
||||
|
||||
**Step 4: Document Issues**
|

Create issue log:
|
||||
```
|
||||
Slide # | Issue Type | Description | Priority
|
||||
--------|-----------|-------------|----------
|
||||
3 | Text overflow | Bullet 4 extends beyond box | High
|
||||
7 | Overlap | Figure overlaps with caption | High
|
||||
12 | Font size | Axis labels too small | Medium
|
||||
```
|
||||
|
||||
**Step 5: Apply Fixes**
|
||||
|
||||
Make corrections to source files:
|
||||
- PowerPoint: Edit text boxes, resize elements
|
||||
- Beamer: Adjust LaTeX code, recompile
|
||||
|
||||
**Step 6: Re-Validate**
|
||||
|
||||
Repeat Steps 1-5 until no critical issues remain.
|
||||
|
||||
**Stopping Criteria**:
|
||||
- No text overflow
|
||||
- No inappropriate overlaps
|
||||
- All text readable (≥18pt equivalent)
|
||||
- Adequate contrast (≥4.5:1)
|
||||
- Professional appearance
|
||||
|
||||
### 7. Timing and Pacing
|
||||
|
||||
Ensure presentations fit allocated time. For comprehensive timing guidance, refer to `assets/timing_guidelines.md`.
|
||||
|
||||
**The One-Slide-Per-Minute Rule**:
|
||||
- General guideline: ~1 slide per minute
|
||||
- Adjust for complex slides (2-3 minutes)
|
||||
- Adjust for simple slides (15-30 seconds)
|
||||
|
||||
**Time Allocation**:
|
||||
- Introduction: 15-20%
|
||||
- Methods: 15-20%
|
||||
- Results: 40-50% (MOST TIME)
|
||||
- Discussion: 15-20%
|
||||
- Conclusion: 5%
|
||||
|
||||
**Practice Requirements**:
|
||||
- 5-minute talk: Practice 5-7 times
|
||||
- 15-minute talk: Practice 3-5 times
|
||||
- 45-minute talk: Practice 3-4 times
|
||||
- Defense: Practice 4-6 times
|
||||
|
||||
**Timing Checkpoints**:
|
||||
|
||||
For 15-minute talk:
|
||||
- 3-4 minutes: Finishing introduction
|
||||
- 7-8 minutes: Halfway through results
|
||||
- 12-13 minutes: Starting conclusions
|
||||
|
||||
**Emergency Strategies**:
|
||||
- Running behind: Skip backup slides (prepare in advance)
|
||||
- Running ahead: Expand examples, slow slightly
|
||||
- Never skip conclusions
|
||||
|
||||
### 8. Validation and Quality Assurance
|
||||
|
||||
**Automated Validation**:
|
||||
```bash
|
||||
# Validate slide count, timing, file size
|
||||
python scripts/validate_presentation.py presentation.pdf --duration 15
|
||||
|
||||
# Generates report on:
|
||||
# - Slide count vs. recommended range
|
||||
# - File size warnings
|
||||
# - Slide dimensions
|
||||
# - Font size issues (PowerPoint)
|
||||
# - Compilation success (Beamer)
|
||||
```
|
||||
|
||||
**Manual Validation Checklist**:
|
||||

|
||||
|
||||
## Workflow for Presentation Development
|
||||
|
||||
### Stage 1: Planning (Before Creating Slides)
|
||||
|
||||
**Define Context**:
|
||||
1. What type of talk? (Conference, seminar, defense, etc.)
|
||||
2. How long? (Duration in minutes)
|
||||
3. Who is the audience? (Specialists, general, mixed)
|
||||
4. What's the venue? (Room size, A/V setup, virtual/in-person)
|
||||
5. What happens after? (Q&A, discussion, networking)
|
||||
|
||||
**Research and Literature Review** (Use research-lookup skill):
|
||||
1. **Search for background literature**: Find 5-10 key papers establishing context
|
||||
2. **Identify knowledge gaps**: Use research-lookup to find what's unknown
|
||||
3. **Locate comparison studies**: Find papers with similar methods or results
|
||||
4. **Gather supporting citations**: Collect papers supporting your interpretations
|
||||
5. **Build reference list**: Create .bib file or citation list for slides
|
||||
6. **Note key findings to cite**: Document specific results to reference
|
||||
|
||||
**Develop Content Outline**:
|
||||
1. Identify 1-3 core messages
|
||||
2. Select key findings to present
|
||||
3. Choose essential figures (typically 3-6 for 15-min talk)
|
||||
4. Plan narrative arc with proper citations
|
||||
5. Allocate time by section
|
||||
|
||||
**Example Outline for 15-Minute Talk**:
|
||||
```
|
||||
1. Title (30 sec)
|
||||
2. Hook: Compelling problem (60 sec) [Cite 1-2 papers via research-lookup]
|
||||
3. Background (90 sec) [Cite 3-4 key papers establishing context]
|
||||
4. Research question (45 sec) [Cite papers showing gap]
|
||||
5. Methods overview (2 min)
|
||||
6-8. Main result 1 (3 min, 3 slides)
|
||||
9-10. Main result 2 (2 min, 2 slides)
|
||||
11-12. Result 3 or validation (2 min, 2 slides)
|
||||
13-14. Discussion and implications (2 min) [Compare to 2-3 prior studies]
|
||||
15. Conclusions (45 sec)
|
||||
16. Acknowledgments (15 sec)
|
||||
|
||||
NOTE: Use research-lookup to find papers for background (slides 2-4)
|
||||
and discussion (slides 13-14) BEFORE creating slides.
|
||||
```
|
||||
|
||||
### Stage 2: Design and Creation
|
||||
|
||||
**Choose Implementation Method**:
|
||||
|
||||
**Option A: PowerPoint (via PPTX skill)**
|
||||
1. Read `assets/powerpoint_design_guide.md`
|
||||
2. Read `document-skills/pptx/SKILL.md`
|
||||
3. Choose approach (programmatic or template-based)
|
||||
4. Create master slides with consistent design
|
||||
5. Build presentation following outline
|
||||
|
||||
**Option B: LaTeX Beamer**
|
||||
1. Read `references/beamer_guide.md`
|
||||
2. Select appropriate template from `assets/`
|
||||
3. Customize theme and colors
|
||||
4. Write content in LaTeX
|
||||
5. Compile to PDF
|
||||
|
||||
**Design Considerations** (Make It Visually Appealing):
|
||||
- **Select MODERN color palette**: Match your topic (biotech=vibrant, physics=sleek, health=warm)
|
||||
- Use pptx skill's color palette examples (Teal & Coral, Bold Red, Deep Purple & Emerald, etc.)
|
||||
- NOT just default blue/gray themes
|
||||
- 3-5 colors with high contrast
|
||||
- **Choose clean fonts**: Sans-serif, large sizes (24pt+ body)
|
||||
- **Plan visual elements**: What images, diagrams, icons for each slide?
|
||||
- **Create varied layouts**: Mix full-figure, two-column, text-overlay (not all bullets)
|
||||
- **Design section dividers**: Visual breaks with striking graphics
|
||||
- **Plan animations/builds**: Control information flow for complex slides
|
||||
- **Add visual interest**: Background images, color blocks, shapes, icons
|
||||
|
||||
### Stage 3: Content Development
|
||||
|
||||
**Populate Slides** (Visual-First Strategy):
|
||||
1. **Start with visuals**: Plan which figures, images, diagrams for each key point
|
||||
2. **Use research-lookup extensively**: Find 8-15 papers for proper citations
|
||||
3. **Create visual backbone first**: Add all figures, charts, images, diagrams
|
||||
4. **Add minimal text as support**: Bullet points complement visuals, don't replace them
|
||||
5. **Design section dividers**: Visual breaks with images or graphics (not just text)
|
||||
6. **Polish title/closing**: Make visually striking, include contact info
|
||||
7. **Add transitions/builds**: Control information flow
|
||||
|
||||
**VISUAL CONTENT REQUIREMENTS** (Make Slides Engaging):
|
||||
- **Images**: Use high-quality photos, illustrations, conceptual graphics
|
||||
- **Icons**: Visual representations of concepts (not decoration)
|
||||
- **Diagrams**: Flowcharts, schematics, process diagrams
|
||||
- **Figures**: Simplified research figures with LARGE labels (18-24pt)
|
||||
- **Charts**: Clean data visualizations with clear messages
|
||||
- **Graphics**: Visual metaphors, conceptual illustrations
|
||||
- **Color blocks**: Use colored shapes to organize content visually
|
||||
- Target: MINIMUM 1-2 strong visual elements per slide
|
||||
|
||||
**Scientific Content** (Research-Backed):
|
||||
- **Citations**: Use research-lookup EXTENSIVELY to find relevant papers
|
||||
- Introduction: Cite 3-5 papers establishing context and gap
|
||||
- Background: Show key prior work visually (not just cite)
|
||||
- Discussion: Cite 3-5 papers for comparison with your results
|
||||
- Use author-year format (Smith et al., 2023) for readability
|
||||
- Citations establish credibility and scientific rigor
|
||||
- **Figures**: Simplified from papers, LARGE labels (18-24pt minimum)
|
||||
- **Equations**: Large, clear, explain each term (use sparingly)
|
||||
- **Tables**: Minimal, highlight key comparisons (not data dumps)
|
||||
- **Code/Algorithms**: Use syntax highlighting, keep brief
|
||||
|
||||
**Text Guidelines** (Less is More):
|
||||
- Bullet points, NEVER paragraphs
|
||||
- 3-4 bullets per slide (max 6 only if essential)
|
||||
- 4-6 words per bullet (shorter than 6×6 rule)
|
||||
- Key terms in bold
|
||||
- Text is SUPPORTING ROLE, visuals are stars
|
||||
- Use builds to control pacing
|
||||
|
||||
### Stage 4: Visual Validation
|
||||
|
||||
**Generate Images**:
|
||||
```bash
|
||||
# Convert PDF to images
|
||||
python scripts/pdf_to_images.py presentation.pdf review/slides
|
||||
|
||||
# Or create thumbnail grid
|
||||
python ../document-skills/pptx/scripts/thumbnail.py presentation.pptx review/grid
|
||||
```
|
||||
|
||||
**Systematic Review**:
|
||||
1. View each slide image
|
||||
2. Check against issue checklist
|
||||
3. Document problems with slide numbers
|
||||
4. Test readability from distance (view at 50% size)
|
||||
|
||||
**Common Issues to Fix**:
|
||||
- Text extending beyond boundaries
|
||||
- Figures overlapping with text
|
||||
- Font sizes too small
|
||||
- Poor contrast
|
||||
- Misalignment
|
||||
|
||||
**Iteration**:
|
||||
1. Fix identified issues in source
|
||||
2. Regenerate PDF/presentation
|
||||
3. Convert to images again
|
||||
4. Re-inspect
|
||||
5. Repeat until clean
|
||||
|
||||
### Stage 5: Practice and Refinement
|
||||
|
||||
**Practice Schedule**:
|
||||
- Run 1: Rough draft (will run long)
|
||||
- Run 2: Smooth transitions
|
||||
- Run 3: Exact timing
|
||||
- Run 4: Final polish
|
||||
- Run 5+: Maintenance (day before, morning of)
|
||||
|
||||
**What to Practice**:
|
||||
- Full talk with timer
|
||||
- Difficult explanations
|
||||
- Transitions between sections
|
||||
- Opening and closing (until flawless)
|
||||
- Anticipated questions
|
||||
|
||||
**Refinement Based on Practice**:
|
||||
- Cut slides if running over
|
||||
- Expand explanations if unclear
|
||||
- Adjust wording for clarity
|
||||
- Mark timing checkpoints
|
||||
- Prepare backup slides
|
||||
|
||||

|
||||
## Common Pitfalls to Avoid
|
||||
|
||||
### Content Mistakes
|
||||
|
||||
**Dry, Boring Presentations** (CRITICAL TO AVOID):
|
||||
- Problem: Text-heavy slides with no visual interest, missing research context
|
||||
- Signs: All bullet points, no images, default templates, no citations
|
||||
- Solution:
|
||||
- Use research-lookup to find 8-15 papers for credible context
|
||||
- Add high-quality visuals to EVERY slide (figures, photos, diagrams, icons)
|
||||
- Choose modern color palette reflecting your topic
|
||||
- Vary slide layouts (not all bullet lists)
|
||||
- Tell a story with visuals, use text sparingly
|
||||
|
||||
**Too Much Content**:
|
||||
- Problem: Trying to include everything from paper
|
||||
- Solution: Focus on 1-2 key findings for short talks, show visually
|
||||
|
||||
**Too Much Text**:
|
||||
- Problem: Full paragraphs on slides, dense bullet points, reading verbatim
|
||||
- Solution: 3-4 bullets with 4-6 words each, let visuals carry the message
|
||||
|
||||
**Missing Research Context**:
|
||||
- Problem: No citations, claims without support, unclear positioning
|
||||
- Solution: Use research-lookup to find papers, cite 3-5 in intro, 3-5 in discussion
|
||||
|
||||
**Poor Narrative**:
|
||||
- Problem: Jumping between topics, no clear story, no flow
|
||||
- Solution: Follow story arc, use visual transitions, maintain thread
|
||||
|
||||
**Rushing Through Results**:
|
||||
- Problem: Brief methods, brief results, long discussion
|
||||
- Solution: Spend 40-50% of time on results, show data visually
|
||||
|
||||
### Design Mistakes
|
||||
|
||||
**Generic, Default Appearance**:
|
||||
- Problem: Using default PowerPoint/Beamer themes without customization, looks dated
|
||||
- Solution: Choose modern color palette, customize fonts/layouts, add visual personality
|
||||
|
||||
**Text-Heavy, Visual-Poor**:
|
||||
- Problem: All bullet point slides, no images or graphics, boring to look at
|
||||
- Solution: Add figures, photos, diagrams, icons to EVERY slide, make visually interesting
|
||||
|
||||
**Small Fonts**:
|
||||
- Problem: Body text <18pt, unreadable from back, looks unprofessional
|
||||
- Solution: 24-28pt for body (not just 18pt minimum), 36-44pt for titles
|
||||
|
||||
**Low Contrast**:
|
||||
- Problem: Light text on light background, poor visibility, hard to read
|
||||
- Solution: High contrast (7:1 preferred, not just 4.5:1 minimum), test with contrast checker
|
||||
|
||||
**Cluttered Slides**:
|
||||
- Problem: Too many elements, no white space, overwhelming
|
||||
- Solution: One idea per slide, 40-50% white space, generous spacing
|
||||
|
||||
**Inconsistent Formatting**:
|
||||
- Problem: Different fonts, colors, layouts slide-to-slide, looks amateurish
|
||||
- Solution: Use master slides, maintain design system, professional consistency
|
||||
|
||||
**Missing Visual Hierarchy**:
|
||||
- Problem: Everything same size and color, no emphasis, unclear focus
|
||||
- Solution: Size differences (titles large, body medium), color for emphasis, clear focal point
|
||||
|
||||
### Timing Mistakes
|
||||
|
||||
**Not Practicing**:
|
||||
- Problem: First time through is during presentation
|
||||
- Solution: Practice minimum 3 times with timer
|
||||
|
||||
**No Time Checkpoints**:
|
||||
- Problem: Don't realize running behind until too late
|
||||
- Solution: Set 3-4 checkpoints, monitor throughout
|
||||
|
||||
**Going Over Time**:
|
||||
- Problem: Extremely unprofessional, cuts into Q&A
|
||||
- Solution: Practice to exact time, prepare Plan B (slides to skip)
|
||||
|
||||
**Skipping Conclusions**:
|
||||
- Problem: Running out of time, rush through or skip ending
|
||||
- Solution: Never skip conclusions, cut earlier content instead
|
||||
|
||||
## Tools and Scripts
|
||||
|
||||
### Validation Scripts

## Quick Start Guide
|
||||
|
||||
### For a 15-Minute Conference Talk
|
||||
|
||||
1. **Research & Plan** (45 minutes):
|
||||
- **Use research-lookup** to find 8-12 relevant papers for citations
|
||||
- Build reference list (background, comparison studies)
|
||||
- Outline content (intro → methods → 2-3 key results → conclusion)
|
||||
- **Select 3-6 key figures** and identify visual elements for each slide
|
||||
- **Choose modern color palette** matching your topic (see pptx skill examples)
|
||||
- Target 15-18 slides
|
||||
|
||||
2. **Design & Create** (2-3 hours):
|
||||
- Choose PowerPoint (pptx skill) or Beamer (use template)
|
||||
- **Select modern, topic-appropriate color scheme** (NOT default themes)
|
||||
- **Visual-first approach**: Add figures, images, diagrams to EVERY slide
|
||||
- Minimal text with large fonts (24-28pt body, 36-44pt titles)
|
||||
- **Add citations from research-lookup** to intro and discussion slides
|
||||
- Vary layouts (full-figure, two-column, visual overlays)
|
||||
- Emphasize results visually (6-8 slides, figure-focused)
|
||||
|
||||
3. **Validate** (30 minutes):
|
||||
- Convert to images: `python scripts/pdf_to_images.py talk.pdf review/s`
|
||||
- Check for text overflow, overlaps, small fonts
|
||||
- Fix issues and regenerate
|
||||
|
||||
4. **Practice** (2-3 hours):
|
||||
- Practice 3-5 times with timer
|
||||
- Aim for 13-14 minutes (leave buffer)
|
||||
- Record yourself, watch playback
|
||||
- **Prepare for questions** (use research-lookup to anticipate)
|
||||
|
||||
5. **Finalize** (30 minutes):
|
||||
- Create backup slides with extra citations
|
||||
- Save multiple copies
|
||||
- Test on presentation computer
|
||||
- Prepare notes if needed
|
||||
|
||||
Total time: ~7-9 hours for quality presentation with proper literature context
|
||||
|
||||
## Summary: Key Principles
|
||||
|
||||
1. **Visual-First Design**: Every slide needs strong visual element (figure, image, diagram) - avoid text-only slides
|
||||
2. **Research-Backed**: Use research-lookup to find 8-15 papers, cite 3-5 in intro, 3-5 in discussion
|
||||
3. **Modern Aesthetics**: Choose contemporary color palette matching topic, not default themes
|
||||
4. **Minimal Text**: 3-4 bullets, 4-6 words each (24-28pt font), let visuals tell story
|
||||
5. **Structure**: Follow story arc, spend 40-50% on results
|
||||
6. **High Contrast**: 7:1 preferred for professional appearance
|
||||
7. **Varied Layouts**: Mix full-figure, two-column, visual overlays (not all bullets)
|
||||
8. **Timing**: Practice 3-5 times, ~1 slide per minute, never skip conclusions
|
||||
9. **Validation**: Visual review workflow to catch overflow and overlap
|
||||
10. **White Space**: 40-50% of slide empty for visual breathing room
|
||||
|
||||
**Remember**:
|
||||
- **Boring = Forgotten**: Dry, text-heavy slides fail to communicate your science
|
||||
- **Visual + Research = Impact**: Combine compelling visuals with research-backed context
|
||||
- **You are the presentation, slides are visual support**: They should enhance, not replace your talk

# PowerPoint Design Guide for Scientific Presentations
|
||||
|
||||
## Overview
|
||||
|
||||
This guide provides comprehensive instructions for creating professional scientific presentations using PowerPoint, with emphasis on integration with the pptx skill for programmatic creation and best practices for scientific content.
|
||||
|
||||
**CRITICAL**: Avoid dry, text-heavy presentations. Scientific slides should be:
|
||||
- **Visually engaging**: High-quality images, figures, diagrams on EVERY slide
|
||||
- **Research-backed**: Citations from research-lookup for credibility (8-15 papers minimum)
|
||||
- **Modern design**: Contemporary color palettes, not default themes
|
||||
- **Minimal text**: 3-4 bullets with 4-6 words each, visuals do the talking
|
||||
- **Professional polish**: Consistent but varied layouts, generous white space
|
||||
|
||||
**Anti-Pattern Warning**: All-bullet-point slides with black text on white background = instant boredom and forgotten science.
|
||||
|
||||
## Using the PPTX Skill
|
||||
|
||||
### Reference
|
||||
|
||||
For complete technical documentation on PowerPoint creation, refer to:
|
||||
- **Main documentation**: `document-skills/pptx/SKILL.md`
|
||||
- **HTML to PowerPoint workflow**: Detailed in `pptx/html2pptx.md`
|
||||
- **OOXML editing**: For advanced editing in `pptx/ooxml.md`
|
||||
|
||||
### Two Approaches to PowerPoint Creation
|
||||
|
||||
#### 1. Programmatic Creation (html2pptx)
|
||||
|
||||
**Best for**: Creating presentations from scratch with custom designs and data visualizations.
|
||||
|
||||
**Workflow**:
|
||||
1. Read `document-skills/pptx/SKILL.md` completely
|
||||
2. Design slides in HTML with proper dimensions (720pt × 405pt for 16:9)
|
||||
3. Create JavaScript file using `html2pptx()` function
|
||||
4. Add charts and tables using PptxGenJS API
|
||||
5. Generate thumbnails and validate visually
|
||||
6. Iterate based on visual inspection
|
||||
|
||||
**Example Structure**:
|
||||
```javascript
|
||||
const pptx = new PptxGenJS();
|
||||
|
||||
// Add title slide
|
||||
const slide1 = pptx.addSlide();
|
||||
slide1.addText("Your Title", {
|
||||
x: 1, y: 2, w: 8, h: 1,
|
||||
fontSize: 44, bold: true, align: "center"
|
||||
});
|
||||
|
||||
// Add content slide with figure
|
||||
const slide2 = pptx.addSlide();
|
||||
slide2.addText("Results", { x: 0.5, y: 0.5, fontSize: 32 });
|
||||
slide2.addImage({ path: "figure.png", x: 1, y: 1.5, w: 8, h: 4 });
|
||||
|
||||
pptx.writeFile({ fileName: "presentation.pptx" });
|
||||
```
|
||||
|
||||
#### 2. Template-Based Creation
|
||||
|
||||
**Best for**: Using existing PowerPoint templates or editing existing presentations.
|
||||
|
||||
**Workflow**:
|
||||
1. Start with template.pptx
|
||||
2. Use `scripts/rearrange.py` to duplicate/reorder slides
|
||||
3. Use `scripts/inventory.py` to extract text
|
||||
4. Generate replacement text JSON
|
||||
5. Use `scripts/replace.py` to update content
|
||||
6. Validate with thumbnail grids
|
||||
|
||||
**Key Scripts**:
|
||||
- `rearrange.py`: Duplicate and reorder slides
|
||||
- `inventory.py`: Extract all text shapes
|
||||
- `replace.py`: Apply text replacements
|
||||
- `thumbnail.py`: Visual validation
|
||||
|
||||
## Design Principles for Scientific Presentations
|
||||
|
||||
### 1. Layout and Structure
|
||||
|
||||
**Slide Master Setup**:
|
||||
- Create consistent master slides
|
||||
- Define 4-5 layout types (title, content, figure, two-column, closing)
|
||||
- Set default fonts, colors, and spacing
|
||||
- Include placeholders for logos and footers
|
||||
|
||||
**Standard Layouts**:
|
||||
|
||||
**Title Slide**:
|
||||
```

### 2. Typography
|
||||
|
||||
**Font Selection**:
|
||||
- **Primary**: Sans-serif (Arial, Calibri, Helvetica)
|
||||
- **Alternative**: Verdana, Tahoma, Trebuchet MS
|
||||
- **Avoid**: Serif fonts (harder to read on screens), decorative fonts
|
||||
|
||||
**Font Sizes**:
|
||||
- Title slide title: 44-54pt
|
||||
- Slide titles: 32-40pt
|
||||
- Body text: 24-28pt (minimum 18pt)
|
||||
- Captions: 16-20pt
|
||||
- Footer: 10-12pt
|
||||
|
||||
**Text Formatting**:
|
||||
- **Bold**: For emphasis (use sparingly)
|
||||
- **Color**: For highlighting (consistent meaning)
|
||||
- **Size**: For hierarchy
|
||||
- **Alignment**: Left for body, center for titles
|
||||
|
||||
**The 6×6 Rule**:
|
||||
- Maximum 6 bullet points per slide
|
||||
- Maximum 6 words per bullet
|
||||
- Better: 3-4 bullets with 4-8 words each
|
||||
|
||||
### 3. Color Schemes
|
||||
|
||||
**Selecting Colors**:
|
||||
|
||||
Consider your subject matter and audience:
|
||||
- **Academic/Professional**: Navy blue, gray, white with minimal accent
|
||||
- **Biomedical**: Blue and green tones (avoid red-green combinations)
|
||||
- **Technology**: Modern colors (teal, orange, purple)
|
||||
- **Clinical**: Conservative (blue, gray, subdued greens)
|
||||
|
||||
**Example Palettes**:
|
||||
|
||||
**Classic Scientific**:
|
||||
- Background: White (#FFFFFF)
|
||||
- Title: Navy (#1C3D5A)
|
||||
- Text: Dark gray (#2D3748)
|
||||
- Accent: Orange (#E67E22)
|
||||
|
||||
**Modern Research**:
|
||||
- Background: Light gray (#F7FAFC)
|
||||
- Title: Teal (#0A9396)
|
||||
- Text: Charcoal (#2C2C2C)
|
||||
- Accent: Coral (#EE6C4D)
|
||||
|
||||
**High Contrast** (for large venues):
|
||||
- Background: White (#FFFFFF)
|
||||
- Title: Black (#000000)
|
||||
- Text: Dark gray (#1A1A1A)
|
||||
- Accent: Bright blue (#0066CC)
|
||||
|
||||
**Accessibility Guidelines**:
|
||||
- Minimum contrast ratio: 4.5:1 (body text)
|
||||
- Preferred contrast ratio: 7:1 (AAA standard)
|
||||
- Avoid red-green combinations (8% of men are color-blind)
|
||||
- Use patterns or shapes in addition to color for data
|
||||
|
||||
### 4. Visual Elements
|
||||
|
||||
**Figures and Images**:
|
||||
- **Resolution**: Minimum 300 DPI for print, 150 DPI for projection
|
||||
- **Format**: PNG for screenshots, PDF/SVG for vector graphics
|
||||
- **Size**: Large enough to be readable from back of room
|
||||
- **Placement**: Center or use two-column layout
|
||||
|
||||
**Data Visualizations**:
|
||||
- **Simplify** from journal figures (fewer panels, larger text)
|
||||
- **Font sizes**: 18-24pt for axis labels
|
||||
- **Line widths**: 2-4pt thickness
|
||||
- **Colors**: High contrast, color-blind safe
|
||||
- **Labels**: Direct labeling preferred over legends
|
||||
|
||||
**Icons and Shapes**:
|
||||
- Use for visual interest and organization
|
||||
- Consistent style (all outline or all filled)
|
||||
- Size appropriately (not too large or small)
|
||||
- Limit colors (match theme)
|
||||
|
||||
### 5. Animations and Transitions
|
||||
|
||||
**When to Use**:
|
||||
- ✅ Progressive disclosure of bullet points
|
||||
- ✅ Building complex figures incrementally
|
||||
- ✅ Emphasizing key findings
|
||||
- ✅ Showing process steps
|
||||
|
||||
**When to Avoid**:
|
||||
- ❌ Decoration or entertainment
|
||||
- ❌ Every single slide
|
||||
- ❌ Distracting effects (fly in, bounce, spin)
|
||||
|
||||
**Recommended Animations**:
|
||||
- **Appear**: Clean, professional
|
||||
- **Fade**: Subtle transition
|
||||
- **Wipe**: Directional reveal
|
||||
- **Duration**: Fast (0.2-0.3 seconds)
|
||||
- **Trigger**: On click (not automatic)
|
||||
|
||||
**Slide Transitions**:
|
||||
- Use consistent transition throughout (or none)
|
||||
- Recommended: None, Fade, or Push
|
||||
- Avoid: 3D rotations, complex effects
|
||||
- Duration: Very fast (0.3-0.5 seconds)
|
||||
|
||||
## Creating Presentations with PPTX Skill
|
||||
|
||||
### Design-First Workflow
|
||||
|
||||
**Step 0: Choose Modern Color Palette Based on Topic**
|
||||
|
||||
**CRITICAL**: Select colors that reflect your subject matter, not generic defaults.
|
||||
|
||||
**Topic-Based Palette Examples:**
|
||||
- **Biotechnology/Life Sciences**: Teal (#0A9396), Coral (#EE6C4D), Cream (#F4F1DE)
|
||||
- **Neuroscience/Brain Research**: Deep Purple (#722880), Magenta (#D72D51), White
|
||||
- **Machine Learning/AI**: Bold Red (#E74C3C), Orange (#F39C12), Dark Gray (#2C2C2C)
|
||||
- **Physics/Engineering**: Navy (#1C3D5A), Orange (#E67E22), Light Gray (#F7FAFC)
|
||||
- **Medicine/Healthcare**: Teal (#5EA8A7), Coral (#FE4447), White (#FFFFFF)
|
||||
- **Environmental Science**: Sage (#87A96B), Terracotta (#E07A5F), Cream (#F4F1DE)
|
||||
|
||||
See full palette options in pptx skill SKILL.md (lines 76-94).
|
||||
|
||||
**Step 1: Plan Design System** (With Modern Palette)
|
||||
```javascript
|
||||
// Define design constants with MODERN colors (not defaults)
|
||||
const DESIGN = {
|
||||
colors: {
|
||||
primary: "0A9396", // Teal (modern, engaging)
|
||||
accent: "EE6C4D", // Coral (attention-grabbing)
|
||||
text: "2C2C2C", // Charcoal (readable)
|
||||
background: "FFFFFF" // White (clean)
|
||||
},
|
||||
fonts: {
|
||||
title: { size: 40, bold: true, face: "Arial" },
|
||||
heading: { size: 28, bold: true, face: "Arial" },
|
||||
body: { size: 24, face: "Arial" },
|
||||
caption: { size: 16, face: "Arial" }
|
||||
},
|
||||
layout: {
|
||||
margin: 0.5,
|
||||
titleY: 0.5,
|
||||
contentY: 1.5
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
**Step 2: Create Reusable Functions**
|
||||
```javascript
|
||||
function addTitleSlide(pptx, title, subtitle, author) {
|
||||
const slide = pptx.addSlide();
|
||||
slide.background = { color: DESIGN.colors.primary };
|
||||
|
||||
slide.addText(title, {
|
||||
x: 1, y: 2, w: 8, h: 1,
|
||||
fontSize: 44, bold: true, color: "FFFFFF",
|
||||
align: "center"
|
||||
});
|
||||
|
||||
slide.addText(subtitle, {
|
||||
x: 1, y: 3.2, w: 8, h: 0.5,
|
||||
fontSize: 24, color: "FFFFFF",
|
||||
align: "center"
|
||||
});
|
||||
|
||||
slide.addText(author, {
|
||||
x: 1, y: 4, w: 8, h: 0.4,
|
||||
fontSize: 18, color: "FFFFFF",
|
||||
align: "center"
|
||||
});
|
||||
|
||||
return slide;
|
||||
}
|
||||
|
||||
function addContentSlide(pptx, title, bullets) {
|
||||
const slide = pptx.addSlide();
|
||||
|
||||
slide.addText(title, {
|
||||
x: DESIGN.layout.margin,
|
||||
y: DESIGN.layout.titleY,
|
||||
w: 9,
|
||||
h: 0.5,
|
||||
...DESIGN.fonts.heading,
|
||||
color: DESIGN.colors.primary
|
||||
});
|
||||
|
||||
slide.addText(bullets, {
|
||||
x: DESIGN.layout.margin,
|
||||
y: DESIGN.layout.contentY,
|
||||
w: 9,
|
||||
h: 3,
|
||||
...DESIGN.fonts.body,
|
||||
bullet: true
|
||||
});
|
||||
|
||||
return slide;
|
||||
}
|
||||
```
|
||||
|
||||
**Step 3: Build Presentation** (Visual-First Approach)
|
||||
```javascript
|
||||
const pptx = new PptxGenJS();
|
||||
pptx.layout = "LAYOUT_16x9";
|
||||
|
||||
// Title slide with background image or color block
|
||||
const titleSlide = pptx.addSlide();
|
||||
titleSlide.background = { color: DESIGN.colors.primary }; // Bold color background
|
||||
addTitleSlide(
|
||||
pptx,
|
||||
"Research Title",
|
||||
"Subtitle or Conference Name",
|
||||
"Your Name • Institution • Date"
|
||||
);
|
||||
|
||||
// Introduction with image/icon
|
||||
const introSlide = pptx.addSlide();
|
||||
introSlide.addImage({
|
||||
path: "concept_image.png", // Visual representation of concept
|
||||
x: 5, y: 1.5, w: 4, h: 3
|
||||
});
|
||||
introSlide.addText("Background", { x: 0.5, y: 0.5, fontSize: 36, bold: true });
|
||||
introSlide.addText([
|
||||
"Key context point 1 (AuthorA, 2023)",
|
||||
"Key context point 2 (AuthorB, 2022)",
|
||||
"Research gap identified (AuthorC, 2021)"
|
||||
], {
|
||||
x: 0.5, y: 1.5, w: 4, h: 2,
|
||||
fontSize: 24, bullet: true
|
||||
});
|
||||
|
||||
// Results slide - FIGURE DOMINATES
|
||||
const resultsSlide = pptx.addSlide();
|
||||
resultsSlide.addText("Main Finding", { x: 0.5, y: 0.5, fontSize: 32, bold: true });
|
||||
resultsSlide.addImage({
|
||||
path: "results_figure.png", // Large, clear figure
|
||||
x: 0.5, y: 1.5, w: 9, h: 4 // Nearly full slide
|
||||
});
|
||||
// Minimal text annotation only
|
||||
resultsSlide.addText("34% improvement (p < 0.001)", {
|
||||
x: 7, y: 1, fontSize: 20, color: DESIGN.colors.accent, bold: true
|
||||
});
|
||||
|
||||
// Save
|
||||
pptx.writeFile({ fileName: "presentation.pptx" });
|
||||
```
|
||||
|
||||
**Key Changes from Dry Presentations:**
|
||||
- Title slide uses bold background color (not plain white)
|
||||
- Introduction includes relevant image (not just bullets)
|
||||
- Results slide is figure-dominated (not text-dominated)
|
||||
- Citations included in bullets for research context
|
||||
- Text is minimal and supporting, visuals are primary
|
||||
|
||||
### Adding Scientific Content
|
||||
|
||||
**Equations** (as images):
|
||||
```javascript
|
||||
// Render equation as PNG first (using LaTeX or online tool)
|
||||
// Then add to slide
|
||||
slide.addImage({
|
||||
path: "equation.png",
|
||||
x: 2, y: 3, w: 6, h: 1
|
||||
});
|
||||
```
|
||||
|
||||
**Tables**:
|
||||
```javascript
|
||||
slide.addTable([
|
||||
[
|
||||
{ text: "Method", options: { bold: true } },
|
||||
{ text: "Accuracy", options: { bold: true } },
|
||||
{ text: "Time (s)", options: { bold: true } }
|
||||
],
|
||||
["Method A", "0.85", "10"],
|
||||
["Method B", "0.92", "25"],
|
||||
["Method C", "0.88", "15"]
|
||||
], {
|
||||
x: 2, y: 2, w: 6,
|
||||
fontSize: 20,
|
||||
border: { pt: 1, color: "888888" },
|
||||
fill: { color: "F5F5F5" }
|
||||
});
|
||||
```
|
||||
|
||||
**Charts**:
|
||||
```javascript
|
||||
// Bar chart
|
||||
slide.addChart(pptx.ChartType.bar, [
|
||||
{
|
||||
name: "Control",
|
||||
labels: ["Metric 1", "Metric 2", "Metric 3"],
|
||||
values: [45, 67, 82]
|
||||
},
|
||||
{
|
||||
name: "Treatment",
|
||||
labels: ["Metric 1", "Metric 2", "Metric 3"],
|
||||
values: [52, 78, 91]
|
||||
}
|
||||
], {
|
||||
x: 1, y: 1.5, w: 8, h: 4,
|
||||
chartColors: [DESIGN.colors.primary, DESIGN.colors.accent],
|
||||
showTitle: false,
|
||||
showLegend: true,
|
||||
fontSize: 18
|
||||
});
|
||||
```
|
||||
|
||||
## Visual Validation Workflow
|
||||
|
||||
### Generate Thumbnails
|
||||
|
||||
After creating presentation:
|
||||
|
||||
```bash
|
||||
# Create thumbnail grid for quick review
|
||||
python scripts/thumbnail.py presentation.pptx review/thumbnails --cols 4
|
||||
|
||||
# Or for individual slides
|
||||
python scripts/thumbnail.py presentation.pptx review/slide
|
||||
```
|
||||
|
||||
### Inspection Checklist
|
||||
|
||||
For each slide, check:
|
||||
- [ ] Text readable (not cut off or too small)
|
||||
- [ ] No element overlap
|
||||
- [ ] Consistent colors and fonts
|
||||
- [ ] Adequate white space
|
||||
- [ ] Figures clear and properly sized
|
||||
- [ ] Alignment correct
|
||||
|
||||
### Common Issues
|
||||
|
||||
**Text Overflow**:
|
||||
- Reduce font size or text length
|
||||
- Increase text box size
|
||||
- Split into multiple slides
|
||||
|
||||
**Element Overlap**:
|
||||
- Use two-column layout
|
||||
- Reduce element sizes
|
||||
- Adjust positioning
|
||||
|
||||
**Poor Contrast**:
|
||||
- Choose higher contrast colors
|
||||
- Use dark text on light background
|
||||
- Test with contrast checker
|
||||
|
||||
## Templates and Examples
|
||||
|
||||
### Starting from Template
|
||||
|
||||
If you have an existing template:
|
||||
|
||||
1. **Extract template structure**:
|
||||
```bash
|
||||
python scripts/inventory.py template.pptx inventory.json
|
||||
```
|
||||
|
||||
2. **Create thumbnail grid**:
|
||||
```bash
|
||||
python scripts/thumbnail.py template.pptx template_review
|
||||
```
|
||||
|
||||
3. **Analyze layouts** and document which slides to use
|
||||
|
||||
4. **Rearrange slides**:
|
||||
```bash
|
||||
python scripts/rearrange.py template.pptx working.pptx 0,5,5,12,18,22
|
||||
```
|
||||
|
||||
5. **Replace content**:
|
||||
```bash
|
||||
python scripts/replace.py working.pptx replacements.json output.pptx
|
||||
```
|
||||
|
||||
## Best Practices Summary
|
||||
|
||||
### Do's (Make Presentations Engaging)
|
||||
|
||||
- ✅ Use research-lookup to find 8-15 papers for citations
|
||||
- ✅ Add HIGH-QUALITY visuals to EVERY slide (figures, images, diagrams, icons)
|
||||
- ✅ Choose MODERN color palette reflecting your topic (not defaults)
|
||||
- ✅ Keep text MINIMAL (3-4 bullets, 4-6 words each)
|
||||
- ✅ Use LARGE fonts (24-28pt body, 36-44pt titles)
|
||||
- ✅ Vary slide layouts (full-figure, two-column, visual overlays)
|
||||
- ✅ Maintain high contrast (7:1 preferred)
|
||||
- ✅ Generous white space (40-50% of slide)
|
||||
- ✅ Cite papers in intro and discussion (establish credibility)
|
||||
- ✅ Test readability from distance
|
||||
- ✅ Validate visually before presenting
|
||||
|
||||
### Don'ts (Avoid Dry Presentations)
|
||||
|
||||
- ❌ Don't create text-only slides (add visuals to EVERY slide)
|
||||
- ❌ Don't use default themes unchanged (customize for your topic)
|
||||
- ❌ Don't have all bullet-point slides (vary layouts)
|
||||
- ❌ Don't skip research-lookup (presentations need citations too)
|
||||
- ❌ Don't cram too much text on one slide
|
||||
- ❌ Don't use tiny fonts (<24pt for body)
|
||||
- ❌ Don't rely solely on color
|
||||
- ❌ Don't use complex animations
|
||||
- ❌ Don't mix too many font styles
|
||||
- ❌ Don't ignore accessibility
|
||||
- ❌ Don't skip visual validation
|
||||
|
||||
## Accessibility Considerations
|
||||
|
||||
**Color Contrast**:
|
||||
- Use WebAIM contrast checker
|
||||
- Minimum 4.5:1 for normal text
|
||||
- Preferred 7:1 for optimal readability
|
||||
|
||||
**Color Blindness**:
|
||||
- Test with Coblis simulator
|
||||
- Use patterns/shapes with colors
|
||||
- Avoid red-green combinations
|
||||
|
||||
**Readability**:
|
||||
- Sans-serif fonts only
|
||||
- Minimum 18pt, prefer 24pt+

- PowerPoint uses inches
|
||||
- 72 points = 1 inch
|
||||
- Position (x, y) from top-left corner
|
||||
- Size (w, h) for width and height
|
||||
|
||||
### Font Size Guidelines
|
||||
|
||||
| Element | Minimum | Recommended |
|
||||
|---------|---------|-------------|
|
||||
| Title slide | 40pt | 44-54pt |
|
||||
| Slide title | 28pt | 32-40pt |
|
||||
| Body text | 18pt | 24-28pt |
|
||||
| Caption | 14pt | 16-20pt |
|
||||
| Footer | 10pt | 10-12pt |
|
||||
|
||||
### Color Usage
|
||||
|
||||
- **Backgrounds**: White or very light colors
|
||||
- **Text**: Dark (black/dark gray) on light, or white on dark
|
||||
- **Accents**: One or two accent colors max
|
||||
- **Data**: Color-blind safe palettes (blue/orange)
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
**Problem**: Text appears cut off
|
||||
- **Solution**: Increase text box size or reduce font size
|
||||
|
||||
**Problem**: Figures are blurry
|
||||
- **Solution**: Use higher resolution images (300 DPI)
|
||||
|
||||
**Problem**: Colors look different when projected
|
||||
- **Solution**: Test with projector beforehand, use high contrast
|
||||
|
||||
**Problem**: File size too large
|
||||
- **Solution**: Compress images, reduce image resolution
|
||||
|
||||
**Problem**: Animations not working
|
||||
- **Solution**: Check PowerPoint version compatibility
|
||||
|
||||
## Conclusion
|
||||
|
||||
Effective PowerPoint presentations for science require:
|

# Presentation Timing Guidelines
|
||||
|
||||
## Overview
|
||||
|
||||
Proper timing is critical for professional scientific presentations. This guide provides detailed guidelines for slide counts, time allocation, pacing strategies, and practice techniques to ensure your presentation fits the allotted time while maintaining engagement and clarity.
|
||||
|
||||
## The One-Slide-Per-Minute Rule
|
||||
|
||||
### Basic Guideline
|
||||
|
||||
**Rule of Thumb**: Plan for approximately 1 slide per minute of presentation time.
|
||||
|
||||
**Why It Works**:
|
||||
- Allows adequate time to explain each concept
|
||||
- Accounts for transitions and questions
|
||||
- Provides buffer for variations in pace
|
||||
- Industry-standard baseline for planning
|
||||
|
||||
**Adjustments**:
|
||||
- **Complex slides** (data-heavy, detailed figures): 2-3 minutes each
|
||||
- **Simple slides** (title, section dividers): 15-30 seconds each
|
||||
- **Key result slides**: 2-4 minutes each
|
||||
- **Build slides** (animations): Count as multiple slides
|
||||
|
||||
### Slide Count by Talk Length
|
||||
|
||||
| Duration | Total Slides | Title/Intro | Methods | Results | Discussion | Conclusion |
|
||||
|----------|--------------|-------------|---------|---------|------------|------------|
|
||||
| 5 min | 5-7 | 1-2 | 0-1 | 2-3 | 1 | 1 |
|
||||
| 10 min | 10-12 | 2 | 1-2 | 4-5 | 2-3 | 1 |
|
||||
| 15 min | 15-18 | 2-3 | 2-3 | 6-8 | 3-4 | 1-2 |
|
||||
| 20 min | 20-24 | 3 | 3-4 | 8-10 | 4-5 | 2 |
|
||||
| 30 min | 25-30 | 3-4 | 5-6 | 10-12 | 6-8 | 2 |
|
||||
| 45 min | 35-45 | 4-5 | 8-10 | 15-20 | 8-10 | 2-3 |
|
||||
| 60 min | 45-60 | 5-6 | 10-12 | 20-25 | 10-12 | 3-4 |
|
||||
|
||||
### Exceptions to the Rule
|
||||
|
||||
**When to Use More Slides**:
|
||||
- Many simple concepts to cover
|
||||
- Highly visual presentation (minimal text)
|
||||
- Progressive builds (each build = new "slide")
|
||||
- Fast-paced overview talks
|
||||
|
||||
**When to Use Fewer Slides**:
|
||||
- Deep dive into few concepts
|
||||
- Complex data visualizations
|
||||
- Interactive discussions expected
|
||||
- Technical/mathematical content
|
||||
|
||||

|
||||
|
||||
## Timing Each Slide
|
||||
|
||||
### Simple Slides
|
||||
|
||||
**Title/Section Dividers** (15-30 seconds):
|
||||
- Say title
|
||||
- Brief transition comment
|
||||
- Move on quickly
|
||||
|
||||
**Single Bullet Point Slides** (30-45 seconds):
|
||||
- Read or paraphrase point
|
||||
- Provide 1-2 sentences of explanation
|
||||
- Transition to next
|
||||
|
||||
### Standard Content Slides
|
||||
|
||||
**Bullet Point Slides** (1-2 minutes):
|
||||
- 3-4 bullets: ~1 minute
|
||||
- 5-6 bullets: ~2 minutes
|
||||
- **Strategy**:
|
||||
- Don't read bullets verbatim
|
||||
- Explain each point (15-20 seconds per bullet)
|
||||
- Use builds to control pacing
|
||||
|
||||
**Equation Slides** (1-2 minutes):
|
||||
- Introduce equation context (20 seconds)
|
||||
- Explain each term (40 seconds)
|
||||
- Discuss implications (20-40 seconds)
|
||||
|
||||
### Complex Slides
|
||||
|
||||
**Data Visualization Slides** (2-3 minutes):
|
||||
```
|
||||
30 seconds: Set up (what you're showing)
|
||||
60 seconds: Walk through key patterns
|
||||
30 seconds: Highlight main finding
|
||||
30 seconds: Statistical results
|
||||
30 seconds: Interpretation/transition
|
||||
```
|
||||
|
||||
**Multi-Panel Figures** (2-4 minutes):
|
||||
```
|
||||
Option 1 - Progressive Build:
|
||||
- Show panel 1: 60 seconds
|
||||
- Add panel 2: 60 seconds
|
||||
- Add panel 3: 60 seconds
|
||||
- Integrate: 60 seconds
|
||||
|
||||
Option 2 - All at Once:
|
||||
- Overview: 30 seconds
|
||||
- Panel 1: 60 seconds
|
||||
- Panel 2: 60 seconds
|
||||
- Panel 3: 60 seconds
|
||||
- Integration: 30 seconds
|
||||
```
|
||||
|
||||
**Table Slides** (1-2 minutes):
|
||||
- Don't read every cell
|
||||
- Guide attention: "Notice the top row..."
|
||||
- Highlight key comparison
|
||||
- State statistical result
|
||||
|
||||
## Pacing Strategies
|
||||
|
||||
### Maintaining Steady Pace
|
||||
|
||||
**Natural Checkpoints** (Use these to self-monitor):
|
||||
|
||||
For 15-minute talk:
|
||||
- **3-4 minutes**: Should be finishing introduction
|
||||
- **7-8 minutes**: Should be halfway through results
|
||||
- **12-13 minutes**: Should be starting conclusions
|
||||
|
||||
For 45-minute talk:
|
||||
- **10 minutes**: Finishing introduction
|
||||
- **20 minutes**: Halfway through methods
|
||||
- **35 minutes**: Finishing results
|
||||
- **40 minutes**: In discussion
|
||||
|
||||
### Signs You're Running Behind
|
||||
|
||||
- Rushing through slides
|
||||
- Skipping explanations
|
||||
- Feeling time pressure
|
||||
- Glancing at clock frequently
|
||||
- Audience looking confused
|
||||
|
||||
**Recovery Strategies**:
|
||||
1. Skip backup/secondary slides (prepare these in advance)
|
||||
2. Summarize instead of detailing
|
||||
3. Cut discussion, not results
|
||||
4. NEVER skip conclusions
|
||||
|
||||
### Signs You're Ahead of Schedule
|
||||
|
||||
- Finishing slides too quickly
|
||||
- Running out of things to say
|
||||
- Awkward pauses
|
||||
- Reaching conclusion with time left
|
||||
|
||||
**Adjustment Strategies**:
|
||||
1. Expand on key points naturally
|
||||
2. Provide additional examples
|
||||
3. Take questions mid-talk (if appropriate)
|
||||
4. Slow down slightly (don't add filler)
|
||||
|
||||
## Practice Techniques
|
||||
|
||||
### Practice Schedule
|
||||
|
||||
**Minimum Practice Requirements**:
|
||||
|
||||
| Talk Type | Practice Runs | Time Commitment |
|
||||
|-----------|--------------|-----------------|

||||
|
||||
### Practice Progression
|
||||
|
||||
**Run 1: Rough Draft**
|
||||
- Focus: Get through all slides
|
||||
- Time it (will likely run long)
|
||||
- Identify problem areas
|
||||
- Note where you stumble
|
||||
|
||||
**Run 2: Smoothing**
|
||||
- Focus: Improve transitions
|
||||

|
||||
- Practice Q&A scenarios
|
||||
- Perfect timing
|
||||
|
||||
**Run 5+: Maintenance**
|
||||
- Day before talk
|
||||
- Morning of talk (if time)
|
||||
- Just opening and closing
|
||||
|
||||
### Practice Methods
|
||||
|
||||
**Solo Practice**:
|
||||
```
|
||||
1. Full talk with timer
|
||||
2. Section-by-section focus
|
||||
3. Speak aloud (not mental review)
|
||||
4. Stand and use gestures
|
||||
5. Simulate presentation environment
|
||||
```
|
||||
|
||||
**Recorded Practice**:
|
||||
```
|
||||
1. Video yourself
|
||||
2. Watch playback critically
|
||||
3. Note:
|
||||
- Timing issues
|
||||
- Filler words ("um", "uh", "like")
|
||||
- Body language
|
||||
- Pace variations
|
||||
4. Re-record after improvements
|
||||
```
|
||||
|
||||
**Live Audience Practice**:
|
||||
```
|
||||
1. Lab meeting or colleagues
|
||||
2. Request honest feedback
|
||||
3. Take questions
|
||||
4. Time strictly
|
||||
5. Note:
|
||||
- Confusing sections
|
||||
- Questions asked
|
||||
- Engagement level
|
||||
```
|
||||
|
||||
### Timing Tools
|
||||
|
||||
**During Practice**:
|
||||
- Phone timer (visible)
|
||||
- Stopwatch with lap times
|
||||
- Timer app with alerts
|
||||
- Record for later analysis
|
||||
|
||||
**During Presentation**:
|
||||
- Phone/watch timer (subtle glances)
|
||||
- Session clock (if provided)
|
||||
- Time notes on slides (bottom corner)
|
||||
- Vibrating watch alerts at key checkpoints
|
||||
|
||||
**Timing Notes on Slides**:
|
||||
```
|
||||
Add small text (8pt, corner):
|
||||
Slide 1: "0:00"
|
||||
Slide 5: "3:30"
|
||||
Slide 10: "7:00"
|
||||
Slide 15: "12:00"
|
||||
Slide 18: "14:00"
|
||||
```
|
||||
|
||||
## Handling Time Constraints
|
||||
|
||||
### If Time is Cut Short
|
||||
|
||||
**Scenario**: "We're running behind, can you cut to 10 minutes?"
|
||||
|
||||
**Strategy**:
|
||||
1. Keep introduction (brief)
|
||||
2. Mention methods (30 seconds)
|
||||
3. Show main result only (3 minutes)
|
||||
4. Brief conclusion (30 seconds)
|
||||
5. Skip: Secondary results, detailed discussion
|
||||
|
||||
**Pre-Prepare**:
|
||||
- Know which slides are "must keep"
|
||||
- Mark "optional" slides
|
||||
- Have 5, 10, and 15-minute versions ready
|
||||
|
||||
### If Given Extra Time
|
||||
|
||||
**Scenario**: "Previous speaker cancelled, you have 30 minutes instead of 15"
|
||||
|
||||
**Options**:
|
||||
1. Go deeper on key results
|
||||
2. Show backup slides
|
||||
3. Include additional analyses
|
||||
4. Extend discussion
|
||||
5. Allow more Q&A time
|
||||
|
||||
**Don't**:
|
||||
- Repeat content
|
||||
- Add filler
|
||||
- Slow down artificially
|
||||
- Include low-quality material
|
||||
|
||||
## Question and Answer Timing
|
||||
|
||||
### Including Q&A in Your Time
|
||||
|
||||
**If Q&A is within your slot**:
|
||||
- Plan for 20-30% of time for questions
|
||||
- 15-minute talk: Reserve 3-4 minutes
|
||||
- 45-minute talk: Reserve 10-15 minutes
|
||||
- Finish content 2-3 minutes early
|
||||
|
||||
**Q&A Time Management**:
|
||||
- Brief answers (30-90 seconds each)
|
||||
- "Great question, let me keep this brief..."
|
||||
- Redirect detailed questions: "Let's discuss after"
|
||||
- Moderator or self-police time
|
||||
|
||||
### Separate Q&A Time
|
||||
|
||||
**If Q&A is after your slot**:
|
||||
- Use full allotted time
|
||||
- Finish exactly at time limit
|
||||
- Don't assume extra time
|
||||
- Have backup slides ready
|
||||

## Common Timing Mistakes
|
||||
|
||||
### Mistake 1: Over-Preparing Introduction
|
||||
|
||||
**Problem**: Spending 5 minutes of 15-minute talk on background
|
||||
|
||||
**Solution**:
|
||||
- Limit intro to 15-20% of total time
|
||||
- Jump to your contribution quickly
|
||||
- Save detailed review for discussion
|
||||
|
||||
### Mistake 2: Equal Time Per Slide
|
||||
|
||||
**Problem**: Spending same time on title slide as key result
|
||||
|
||||
**Solution**:
|
||||
- Vary pace based on importance
|
||||
- Rush through simple slides
|
||||
- Linger on key findings
|
||||
|
||||
### Mistake 3: No Time Checkpoints
|
||||
|
||||
**Problem**: Realizing you're behind only at minute 12 of 15
|
||||
|
||||
**Solution**:
|
||||
- Set 3-4 checkpoints
|
||||
- Glance at timer regularly
|
||||
- Adjust in real-time
|
||||
|
||||
### Mistake 4: Skipping Practice
|
||||
|
||||
**Problem**: First time through is during actual presentation
|
||||
|
||||
**Solution**:
|
||||
- Practice minimum 3 times
|
||||
- Time each practice
|
||||
- Get feedback
|
||||
|
||||
### Mistake 5: Not Preparing Plan B
|
||||
|
||||
**Problem**: Run over time with no strategy
|
||||
|
||||
**Solution**:
|
||||
- Know which slides to skip
|
||||
- Have condensed versions ready
|
||||
- Practice shortened version
|
||||
|
||||
## Special Timing Considerations
|
||||
|
||||
### Virtual Presentations
|
||||
|
||||
**Adjustments**:
|
||||
- Slightly slower pace (5-10%)
|
||||
- More explicit transitions
|
||||
- Built-in pauses for lag
|
||||
- Buffer for technical issues
|
||||
|
||||
**Time Allocation**:
|
||||
- Start 1-2 minutes early (tech check)
|
||||
- More time for Q&A (typing delays)
|
||||
- Share slides in advance if possible
|
||||
|
||||
### Poster Spotlight Talks (3 Minutes)
|
||||
|
||||
**Ultra-Tight Timing**:
|
||||
```
|
||||
0:00-0:30 | Title + Context
|
||||
0:30-1:30 | Problem + Approach
|
||||
1:30-2:30 | Key Result (one figure)
|
||||
2:30-3:00 | "Visit poster #42"
|
||||
```
|
||||
|
||||
**Practice**: 10+ times to get exactly right
|
||||
|
||||
### Invited Talks (45-60 Minutes)
|
||||
|
||||
**More Flexibility**:
|
||||
- Can adjust pace based on audience
|
||||
- Welcome interruptions
|
||||
- Conversational style acceptable
|
||||
- Less rigid timing
|
||||
|
||||
**Still Important**:
|
||||
- Have overall time structure
|
||||
- Monitor major checkpoints
|
||||
- Respect Q&A time
|
||||
|
||||
## Summary: Key Timing Principles
|
||||
|
||||
1. **Plan for 1 slide per minute** (adjust for complexity)
|
||||
2. **Spend 40-50% on results**
|
||||
3. **Practice 3-5 times minimum**
|
||||
4. **Set 3-4 time checkpoints**
|
||||
5. **Have Plan B for running over**
|
||||
6. **Never skip conclusions**
|
||||
7. **Finish on time** (non-negotiable)
|
||||
|
||||

Checkpoints (15-min talk):
|
||||
├─ 3-4 min: End of intro
|
||||
├─ 7-8 min: Halfway through results
|
||||
└─ 12-13 min: Starting conclusions
|
||||
|
||||
Emergency Strategies:

# Data Visualization for Slides
|
||||
|
||||
## Overview
|
||||
|
||||
Effective data visualization in presentations differs fundamentally from journal figures. While publications prioritize comprehensive detail, presentation slides must emphasize clarity, impact, and immediate comprehension. This guide covers adapting figures for slides, choosing appropriate chart types, and avoiding common visualization mistakes.
|
||||
|
||||
## Key Principles for Presentation Figures
|
||||
|
||||
### 1. Simplify, Don't Replicate
|
||||
|
||||
**The Core Difference**:
|
||||
- **Journal figures**: Dense, detailed, for careful study
|
||||
- **Presentation figures**: Clear, simplified, for quick understanding
|
||||
|
||||
**Simplification Strategies**:
|
||||
|
||||
**Remove Non-Essential Elements**:
|
||||
- ❌ Minor gridlines
|
||||
- ❌ Detailed legends (label directly instead)
|
||||
- ❌ Multiple panels (split into separate slides)
|
||||
- ❌ Secondary axes (rarely work in presentations)
|
||||
- ❌ Dense tick marks and minor labels
|
||||
|
||||
**Focus on Key Message**:
|
||||
- Show only the data supporting your current point
|
||||
- Subset data if full dataset is overwhelming
|
||||
- Highlight the specific comparison you're discussing
|
||||
- Remove context that isn't immediately relevant
|
||||
|
||||
**Example Transformation**:
|
||||
```
|
||||
Journal Figure:
|
||||
- 6 panels (A-F)
|
||||
- 4 experimental conditions per panel
|
||||
- 50+ data points visible
|
||||
- Complex statistical annotations
|
||||
- Small font labels
|
||||
|
||||
Presentation Version:
|
||||
- 3 separate slides (1-2 panels each)
|
||||
- Focus on key comparison per slide
|
||||
- Large, clear data representation
|
||||
- One statistical result highlighted
|
||||
- Large, readable labels
|
||||
```
|
||||
|
||||
### 2. Emphasize Visual Hierarchy
|
||||
|
||||
**Guide Attention**:
|
||||
- Make key result visually dominant
|
||||
- De-emphasize background or comparison data
|
||||
- Use size, color, and position strategically
|
||||
|
||||
**Techniques**:
|
||||
|
||||
**Color Emphasis**:
|
||||
```
|
||||
Main Result: Bold, saturated color (e.g., blue)
|
||||
Comparison: Muted gray or desaturated color
|
||||
Background: Very light gray or white
|
||||
```
|
||||
|
||||
**Size Emphasis**:
|
||||
```
|
||||
Key line/bar: Thicker (3-4pt)
|
||||
Reference lines: Thinner (1-2pt)
|
||||
Grid lines: Very thin (0.5pt) or remove
|
||||
```
|
||||
|
||||
**Annotation**:
|
||||
```
|
||||
Add text callouts: "34% increase" with arrow
|
||||
Add shapes: Circle key region
|
||||
Add color highlights: Background shading for important area
|
||||
```
|
||||
|
||||
### 3. Maximize Readability
|
||||
|
||||
**Font Sizes for Presentations**:
|
||||
- **Axis labels**: 18-24pt minimum
|
||||
- **Tick labels**: 16-20pt minimum
|
||||
- **Title**: 24-32pt
|
||||
- **Legend**: 16-20pt (or label directly on plot)
|
||||
- **Annotations**: 18-24pt
|
||||
|
||||
**The Distance Test**:
|
||||
- If your figure isn't readable at 2-3 feet from your laptop screen, it won't work in a presentation
|
||||
- Test by stepping back from screen
|
||||
- Better to split into multiple simpler figures
|
||||
|
||||
**Line and Marker Sizes**:
|
||||
- **Lines**: 2-4pt thickness (thicker than journal figures)
|
||||
- **Markers**: 8-12pt size
|
||||
- **Error bars**: 1.5-2pt thickness
|
||||
- **Bars**: Adequate width with clear spacing
|
||||
|
||||
### 4. Use Progressive Disclosure
|
||||
|
||||
**Build Complex Figures Incrementally**:
|
||||
|
||||
Instead of showing complete figure at once:
|
||||
1. **Baseline**: Show axes and basic setup
|
||||
2. **Data Group 1**: Add first dataset
|
||||
3. **Data Group 2**: Add comparison dataset
|
||||
4. **Highlight**: Emphasize key difference
|
||||
5. **Interpretation**: Add annotation with finding
|
||||
|
||||
**Benefits**:
|
||||
- Controls audience attention
|
||||
- Prevents information overload
|
||||
- Guides interpretation
|
||||
- Emphasizes narrative structure
|
||||
|
||||
**Implementation**:
|
||||
- PowerPoint: Use animation to reveal layers
|
||||
- Beamer: Use `\pause` or overlays
|
||||
- Static: Create sequence of slides building the figure
|
||||
|
||||
## Chart Types and When to Use Them
|
||||
|
||||
### Bar Charts
|
||||
|
||||
**Best For**:
|
||||
- Comparing discrete categories
|
||||
- Showing counts or frequencies
|
||||
- Highlighting differences between groups
|
||||
|
||||
**Presentation Optimization**:
|
||||
```
|
||||
✅ DO:
|
||||
- Large, clear bars with adequate spacing
|
||||
- Horizontal bars for long category names
|
||||
- Direct labeling on bars (not legend)
|
||||
- Order by value (highest to lowest) unless natural order exists
|
||||
- Start y-axis at zero for accurate visual comparison
|
||||
|
||||
❌ DON'T:
|
||||
- Too many categories (max 8-10)
|
||||
- 3D bars (distorts perception)
|
||||
- Multiple grouped comparisons (split to separate slides)
|
||||
- Decorative patterns or gradients
|
||||
```
|
||||
|
||||
**Example Enhancement**:
|
||||
```
|
||||
Before: 12 categories, small fonts, legend
|
||||
After: Top 6 categories only, large fonts, direct labels, key bar highlighted
|
||||
```
|
||||
|
||||
### Line Graphs
|
||||
|
||||
**Best For**:
|
||||
- Trends over time
|
||||
- Continuous data relationships
|
||||
- Comparing trajectories
|
||||
|
||||
**Presentation Optimization**:
|
||||
```
|
||||
✅ DO:
|
||||
- Thick lines (2-4pt)
|
||||
- Distinct colors AND line styles (solid, dashed, dotted)
|
||||
- Direct line labeling (at end of lines, not legend)
|
||||
- Highlight key line with color/thickness
|
||||
- Minimal gridlines or none
|
||||
- Clear markers at data points
|
||||
|
||||
❌ DON'T:
|
||||
- More than 4-5 lines per plot
|
||||
- Similar colors (ensure high contrast)
|
||||
- Small markers or thin lines
|
||||
- Cluttered with excess gridlines
|
||||
```
|
||||
|
||||
**Time Series Tips**:
|
||||
- Mark key events or interventions with vertical lines
|
||||
- Annotate important time points
|
||||
- Use shaded regions for different phases
|
||||
|
||||
### Scatter Plots
|
||||
|
||||
**Best For**:
|
||||
- Relationships between two variables
|
||||
- Correlations
|
||||
- Distributions
|
||||
- Outliers
|
||||
|
||||
**Presentation Optimization**:
|
||||
```
|
||||
✅ DO:
|
||||
- Large, distinct markers (8-12pt)
|
||||
- Color code groups clearly
|
||||
- Show trendline if discussing correlation
|
||||
- Annotate key points (outliers, examples)
|
||||
- Report R² or p-value directly on plot
|
||||
|
||||
❌ DON'T:
|
||||
- Overplot (too many overlapping points)
|
||||
- Small markers
|
||||
- Multiple marker types that look similar
|
||||
- Missing scale information
|
||||
```
|
||||
|
||||
**Overplotting Solutions**:
|
||||
- Transparency (alpha) for overlapping points
|
||||
- Hexbin or density plots for very large datasets
|
||||
- Random jitter for discrete data
|
||||
- Marginal distributions on axes
|
||||
|
||||
### Box Plots / Violin Plots
|
||||
|
||||
**Best For**:
|
||||
- Distribution comparisons
|
||||
- Showing variability and outliers
|
||||
- Multiple group comparisons
|
||||
|
||||
**Presentation Optimization**:
|
||||
```
|
||||
✅ DO:
|
||||
- Large, clear boxes
|
||||
- Color code groups
|
||||
- Add individual data points if n is small (< 30)
|
||||
- Annotate median or mean values
|
||||
- Explain components (quartiles, whiskers) first time shown
|
||||
|
||||
❌ DON'T:
|
||||
- Assume audience knows box plot conventions
|
||||
- Use without brief explanation
|
||||
- Too many groups (max 6-8)
|
||||
- Omit axis labels and units
|
||||
```
|
||||
|
||||
**First Use**:
|
||||
If your audience may be unfamiliar, briefly explain: "Box shows middle 50% of data, line is median, whiskers show range"
|
||||
|
||||
### Heatmaps
|
||||
|
||||
**Best For**:
|
||||
- Matrix data
|
||||
- Gene expression or correlation patterns
|
||||
- Large datasets with patterns
|
||||
|
||||
**Presentation Optimization**:
|
||||
```
|
||||
✅ DO:
|
||||
- Large cells (readable grid)
|
||||
- Clear, intuitive color scale (diverging or sequential)
|
||||
- Label rows and columns with large fonts
|
||||
- Show color scale legend prominently
|
||||
- Cluster or order meaningfully
|
||||
- Highlight key region with border
|
||||
|
||||
❌ DON'T:
|
||||
- Too many rows/columns (200×200 matrix unreadable)
|
||||
- Poor color scales (rainbow, red-green)
|
||||
- Missing dendrograms if claiming clusters
|
||||
- Tiny labels
|
||||
```
|
||||
|
||||
**Simplification**:
|
||||
- Show subset of most interesting rows/columns
|
||||
- Zoom to relevant region
|
||||
- Split large heatmap across multiple slides
|
||||
|
||||
### Network Diagrams
|
||||
|
||||
**Best For**:
|
||||
- Relationships and connections
|
||||
- Pathways and networks
|
||||
- Hierarchical structures
|
||||
|
||||
**Presentation Optimization**:
|
||||
```
|
||||
✅ DO:
|
||||
- Large nodes and labels
|
||||
- Clear edge directionality (arrows)
|
||||
- Color or size code importance
|
||||
- Highlight path of interest
|
||||
- Simplify to essential connections
|
||||
- Use layout that minimizes crossing edges
|
||||
|
||||
❌ DON'T:
|
||||
- Show entire complex network at once
|
||||
- Hairball diagrams (too many connections)
|
||||
- Small labels on nodes
|
||||
- Unclear what nodes and edges represent
|
||||
```
|
||||
|
||||
**Build Strategy**:
|
||||
1. Show simplified structure
|
||||
2. Add key nodes progressively
|
||||
3. Highlight path or subnetwork of interest
|
||||
4. Annotate with functional interpretation
|
||||
|
||||
### Statistical Plots
|
||||
|
||||
**Kaplan-Meier Survival Curves**:
|
||||
```
|
||||
✅ Optimize:
|
||||
- Thick lines (3-4pt)
|
||||
- Show confidence intervals as shaded regions
|
||||
- Mark censored observations clearly
|
||||
- Report hazard ratio and p-value on plot
|
||||
- Extend axes to show full follow-up
|
||||
```
|
||||
|
||||
**Forest Plots**:
|
||||
```
|
||||
✅ Optimize:
|
||||
- Large markers (diamonds or squares)
|
||||
- Clear confidence interval bars
|
||||
- Large font for study names
|
||||
- Highlight overall estimate
|
||||
- Show line of no effect prominently
|
||||
```
|
||||
|
||||
**ROC Curves**:
|
||||
```
|
||||
✅ Optimize:
|
||||
- Thick curve line
|
||||
- Show diagonal reference line (AUC = 0.5)
|
||||
- Report AUC with confidence interval on plot
|
||||
- Mark optimal threshold if discussing cutpoint
|
||||
- Compare ≤ 3 curves per plot
|
||||
```
|
||||
|
||||
## Color in Data Visualizations
|
||||
|
||||
### Sequential Color Scales
|
||||
|
||||
**When to Use**: Ordered data (low to high)
|
||||
|
||||
**Good Palettes**:
|
||||
- Blues: Light blue → Dark blue
|
||||
- Greens: Light green → Dark green
|
||||
- Grays: Light gray → Black
|
||||
- Viridis: Yellow → Purple (perceptually uniform)
|
||||
|
||||
**Avoid**:
|
||||
- Rainbow scales (non-uniform perception)
|
||||
- Red-green scales (color blindness)
|
||||
|
||||
### Diverging Color Scales
|
||||
|
||||
**When to Use**: Data with meaningful midpoint (e.g., +/− change, correlation from -1 to +1)
|
||||
|
||||
**Good Palettes**:
|
||||
- Blue → White → Red
|
||||
- Purple → White → Orange
|
||||
- Blue → Gray → Orange
|
||||
|
||||
**Key Principle**: Midpoint should be visually neutral (white or light gray)
|
||||
|
||||
### Categorical Colors
|
||||
|
||||
**When to Use**: Distinct groups with no order
|
||||
|
||||
**Good Practices**:
|
||||
- Maximum 5-7 colors for clarity
|
||||
- High contrast between adjacent categories
|
||||
- Color-blind safe combinations
|
||||
- Consistent color mapping across slides
|
||||
|
||||
**Example Set**:
|
||||
```
|
||||
Blue (#0173B2)
|
||||
Orange (#DE8F05)
|
||||
Green (#029E73)
|
||||
Purple (#CC78BC)
|
||||
Red (#CA3542)
|
||||
```
|
||||
|
||||
### Highlight Colors
|
||||
|
||||
**Strategy**: Use color to direct attention
|
||||
|
||||
```
|
||||
Main Result: Bright, saturated color (e.g., blue)
|
||||
Comparison: Neutral (gray) or muted color
|
||||
Background: Very light gray or white
|
||||
```
|
||||
|
||||
**Example Application**:
|
||||
- Bar chart: Key bar in blue, others in light gray
|
||||
- Line plot: Main line in bold blue, reference lines in thin gray
|
||||
- Scatter: Group of interest in color, others faded
|
||||
|
||||
## Common Visualization Mistakes
|
||||
|
||||
### Mistake 1: Overwhelming Complexity
|
||||
|
||||
**Problem**: Showing too much data at once
|
||||
|
||||
**Example**:
|
||||
- Figure with 12 panels
|
||||
- Each panel has 6 experimental conditions
|
||||
- Tiny fonts and dense layout
|
||||
- Audience has 10 seconds to process
|
||||
|
||||
**Solution**:
|
||||
- Split into 3-4 slides
|
||||
- One comparison per slide
|
||||
- Focus on key result
|
||||
- Build understanding progressively
|
||||
|
||||
### Mistake 2: Illegible Labels
|
||||
|
||||
**Problem**: Text too small to read
|
||||
|
||||
**Common Issues**:
|
||||
- 8-10pt axis labels (need ≥18pt)
|
||||
- Tiny legend text
|
||||
- Subscripts and superscripts disappear
|
||||
- Fine-print p-values
|
||||
|
||||
**Solution**:
|
||||
- Recreate figures for presentation (don't use journal versions directly)
|
||||
- Test readability from distance
|
||||
- Remove or enlarge small text
|
||||
- Put detailed statistics in notes
|
||||
|
||||
### Mistake 3: Chart Junk
|
||||
|
||||
**Problem**: Unnecessary decorative elements
|
||||
|
||||
**Examples**:
|
||||
- 3D effects on 2D data
|
||||
- Excessive gridlines
|
||||
- Distracting backgrounds
|
||||
- Decorative borders or shadows
|
||||
- Animation for decoration only
|
||||
|
||||
**Solution**:
|
||||
- Remove all non-data ink
|
||||
- Maximize data-ink ratio
|
||||
- Clean, minimal design
|
||||
- Let data be the focus
|
||||
|
||||
### Mistake 4: Misleading Scales
|
||||
|
||||
**Problem**: Visual representation distorts data
|
||||
|
||||
**Examples**:
|
||||
- Bar charts not starting at zero
|
||||
- Truncated y-axes exaggerating differences
|
||||
- Inconsistent scales between panels
|
||||
- Log scales without clear labeling
|
||||
|
||||
**Solution**:
|
||||
- Bar charts: Always start at zero
|
||||
- Line charts: Can truncate, but make clear
|
||||
- Label log scales explicitly
|
||||
- Maintain consistent scales for comparisons
|
||||
|
||||
### Mistake 5: Poor Color Choices
|
||||
|
||||
**Problem**: Colors reduce clarity or accessibility
|
||||
|
||||
**Examples**:
|
||||
- Red-green for color-blind audience
|
||||
- Low contrast (yellow on white)
|
||||
- Too many colors
|
||||
- Inconsistent color meaning
|
||||
|
||||
**Solution**:
|
||||
- Use color-blind safe palettes
|
||||
- Test contrast (minimum 4.5:1)
|
||||
- Limit to 5-7 colors maximum
|
||||
- Consistent meaning across slides
|
||||
|
||||
### Mistake 6: Missing Context
|
||||
|
||||
**Problem**: Audience can't interpret visualization
|
||||
|
||||
**Missing Elements**:
|
||||
- Axis labels or units
|
||||
- Sample sizes (n)
|
||||
- Error bar meaning (SEM vs SD vs CI)
|
||||
- Statistical significance indicators
|
||||
- Scale or reference points
|
||||
|
||||
**Solution**:
|
||||
- Label everything clearly
|
||||
- Define abbreviations
|
||||
- Report key statistics on plot
|
||||
- Provide reference for comparison
|
||||
|
||||
### Mistake 7: Inefficient Chart Type
|
||||
|
||||
**Problem**: Wrong visualization for data type
|
||||
|
||||
**Examples**:
|
||||
- Pie chart for >5 categories (use bar chart)
|
||||
- 3D pie chart (especially bad)
|
||||
- Dual y-axes (confusing)
|
||||
- Line plot for discrete categories (use bar chart)
|
||||
|
||||
**Solution**:
|
||||
- Match chart type to data type
|
||||
- Consider what comparison you're showing
|
||||
- Choose format that makes pattern obvious
|
||||
- Test if message is immediately clear
|
||||
|
||||
## Progressive Disclosure Techniques
|
||||
|
||||
### Building a Complex Figure
|
||||
|
||||
**Scenario**: Showing multi-panel experimental result
|
||||
|
||||
**Approach 1: Sequential Panels**
|
||||
```
|
||||
Slide 1: Panel A only (baseline condition)
|
||||
Slide 2: Panels A+B (add treatment effect)
|
||||
Slide 3: Panels A+B+C (add time course)
|
||||
Slide 4: All panels with interpretation overlay
|
||||
```
|
||||
|
||||
**Approach 2: Layered Data**
|
||||
```
|
||||
Slide 1: Axes and experimental design schematic
|
||||
Slide 2: Add control group data
|
||||
Slide 3: Add treatment group data
|
||||
Slide 4: Highlight difference, show statistics
|
||||
```
|
||||
|
||||
**Approach 3: Zoom and Context**
|
||||
```
|
||||
Slide 1: Full dataset overview
|
||||
Slide 2: Zoom to interesting region
|
||||
Slide 3: Highlight specific points in zoomed view
|
||||
```
|
||||
|
||||
### Animation vs. Multiple Slides
|
||||
|
||||
**Use Animation** (PowerPoint/Beamer overlays):
|
||||
- Building bullet points
|
||||
- Adding layers to same plot
|
||||
- Highlighting different regions sequentially
|
||||
- Smooth transitions within a concept
|
||||
|
||||
**Use Separate Slides**:
|
||||
- Different data or experiments
|
||||
- Major conceptual shifts
|
||||
- Want to return to previous view
|
||||
- Need to control timing flexibly
|
||||
|
||||
## Figure Preparation Workflow
|
||||
|
||||
### Step 1: Start with High-Quality Source
|
||||
|
||||
**For Generated Figures**:
|
||||
- Export at high resolution (300 DPI minimum)
|
||||
- Vector formats preferred (PDF, SVG)
|
||||
- Large size (can scale down, not up)
|
||||
- Clean, professional appearance
|
||||
|
||||
**For Published Figures**:
|
||||
- Request high-resolution versions from authors/publishers
|
||||
- Recreate if source not available
|
||||
- Check reuse permissions
|
||||
|
||||
### Step 2: Simplify for Presentation
|
||||
|
||||
**Edit in Graphics Software**:
|
||||
- Remove non-essential panels
|
||||
- Enlarge fonts and labels
|
||||
- Increase line widths and marker sizes
|
||||
- Remove or simplify legends
|
||||
- Add direct labels
|
||||
- Remove excess gridlines
|
||||
|
||||
**Tools**:
|
||||
- Adobe Illustrator (vector editing)
|
||||
- Inkscape (free vector editing)
|
||||
- PowerPoint/Keynote (basic editing)
|
||||
- Python/R (programmatic recreation)
|
||||
|
||||
### Step 3: Optimize for Projection
|
||||
|
||||
**Check**:
|
||||
- ✅ Readable from 10 feet away
|
||||
- ✅ High contrast between elements
|
||||
- ✅ Large enough to fill significant slide area
|
||||
- ✅ Maintains quality when projected
|
||||
- ✅ Works in various lighting conditions
|
||||
|
||||
**Test**:
|
||||
- View on different screens
|
||||
- Project if possible before talk
|
||||
- Print at small scale (simulates distance)
|
||||
- Check in grayscale (color-blind simulation)
|
||||
|
||||
### Step 4: Add Context and Annotations
|
||||
|
||||
**Enhancements**:
|
||||
- Arrows pointing to key features
|
||||
- Text boxes with key findings ("p < 0.001")
|
||||
- Circles or rectangles highlighting regions
|
||||
- Color coding matched to verbal description
|
||||
- Reference lines or benchmarks
|
||||
|
||||
**Verbal Integration**:
|
||||
- Plan what you'll say about each element
|
||||
- Use "Notice that..." or "Here you can see..."
|
||||
- Point to specific features during talk
|
||||
- Explain axes and scales first time shown
|
||||
|
||||
## Recreating Journal Figures for Presentations
|
||||
|
||||
### When to Recreate
|
||||
|
||||
**Recreate When**:
|
||||
- Original has small fonts
|
||||
- Too many panels for one slide
|
||||
- Multiple comparisons to parse
|
||||
- Colors not accessible
|
||||
- Data available to you
|
||||
|
||||
**Reuse When**:
|
||||
- Already simple and clear
|
||||
- Appropriate font sizes
|
||||
- Single focused message
|
||||
- High resolution available
|
||||
- Remaking not feasible
|
||||
|
||||
### Recreation Tools
|
||||
|
||||
**Python (matplotlib, seaborn)**:
|
||||
```python
|
||||
import matplotlib.pyplot as plt
|
||||
import seaborn as sns
|
||||
|
||||
# Set presentation-friendly defaults
|
||||
plt.rcParams['font.size'] = 18
|
||||
plt.rcParams['axes.linewidth'] = 2
|
||||
plt.rcParams['lines.linewidth'] = 3
|
||||
plt.rcParams['figure.figsize'] = (10, 6)
|
||||
|
||||
# Create plot with large, clear elements
|
||||
# Export as high-res PNG or PDF
|
||||
```
|
||||
|
||||
**R (ggplot2)**:
|
||||
```r
|
||||
library(ggplot2)
|
||||
|
||||
# Presentation theme
|
||||
theme_presentation <- theme_minimal() +
|
||||
theme(
|
||||
text = element_text(size = 18),
|
||||
axis.text = element_text(size = 16),
|
||||
axis.title = element_text(size = 20),
|
||||
legend.text = element_text(size = 16)
|
||||
)
|
||||
|
||||
# Apply to plots
|
||||
ggplot(data, aes(x, y)) + geom_point(size=4) + theme_presentation
|
||||
```
|
||||
|
||||
**GraphPad Prism**:
|
||||
- Increase font sizes in Format Axes
|
||||
- Thicken lines in Format Graph
|
||||
- Enlarge symbols
|
||||
- Export as high-resolution image
|
||||
|
||||
**Excel/PowerPoint**:
|
||||
- Select chart, Format → Text Options → Size (increase to 18-24pt)
|
||||
- Format → Line → Width (increase to 2-3pt)
|
||||
- Format → Marker → Size (increase to 10-12pt)
|
||||
|
||||

# Presentation Structure Guide
|
||||
|
||||
## Overview
|
||||
|
||||
Effective scientific presentations follow a clear narrative structure that guides the audience through your research story. This guide provides structure templates for different talk lengths and contexts, helping you organize content for maximum impact and clarity.
|
||||
|
||||
## Core Narrative Structure
|
||||
|
||||
All scientific presentations should follow a story arc that engages, informs, and persuades:
|
||||
|
||||
1. **Hook**: Grab attention immediately (30 seconds - 1 minute)
|
||||
2. **Context**: Establish the research area and importance (5-10% of talk)
|
||||
3. **Problem/Gap**: Identify what's unknown or problematic (5-10% of talk)
|
||||
4. **Approach**: Explain your solution or method (15-25% of talk)
|
||||
5. **Results**: Present key findings (40-50% of talk)
|
||||
6. **Implications**: Discuss meaning and impact (15-20% of talk)
|
||||
7. **Closure**: Memorable conclusion and call to action (1-2 minutes)
|
||||
|
||||
This arc mirrors the scientific method while maintaining narrative flow that keeps audiences engaged.
|
||||
|
||||
## Slide Count Guidelines
|
||||
|
||||
**General Rule**: Approximately 1 slide per minute, with adjustments based on content complexity.
|
||||
|
||||
| Talk Duration | Total Slides | Title/Intro | Methods | Results | Discussion | Conclusion |
|
||||
|---------------|--------------|-------------|---------|---------|------------|------------|
|
||||
| 5 minutes (lightning) | 5-7 | 1-2 | 0-1 | 2-3 | 1 | 1 |
|
||||
| 10 minutes (short) | 10-12 | 2 | 1-2 | 4-5 | 2-3 | 1 |
|
||||
| 15 minutes (conference) | 15-18 | 2-3 | 2-3 | 6-8 | 3-4 | 1-2 |
|
||||
| 20 minutes (extended) | 20-24 | 3 | 3-4 | 8-10 | 4-5 | 2 |
|
||||
| 30 minutes (seminar) | 25-30 | 3-4 | 5-6 | 10-12 | 6-8 | 2 |
|
||||
| 45 minutes (keynote) | 35-45 | 4-5 | 8-10 | 15-20 | 8-10 | 2-3 |
|
||||
| 60 minutes (lecture) | 45-60 | 5-6 | 10-12 | 20-25 | 10-12 | 3-4 |
|
||||
|
||||
**Adjustments**:
|
||||
- **Complex data**: Reduce slide count (spend more time per slide)
|
||||
- **Simple concepts**: Can increase slide count slightly
|
||||
- **Heavy animations**: Count as multiple slides if building incrementally
|
||||
- **Q&A included**: Reduce content slides by 20-30%
|
||||
|
||||
## Structure by Talk Length

|
||||
- Use examples and analogies liberally
|
||||
- Build complexity gradually
|
||||
- Include interactive elements if possible
|
||||
- Provide resources for further learning
|
||||
- Repeat key concepts at transitions
|
||||
- Use consistent visual templates for concept types
|
||||
|
||||
## Opening Strategies
|
||||
|
||||
### The Hook (First 30-60 seconds)
|
||||
|
||||
Your opening sets the tone and captures attention. Effective hooks:
|
||||
|
||||
**1. Surprising Statistic**
|
||||
- "Every year, X million people experience Y, yet only Z% receive effective treatment."
|
||||
- Works well for applied research with societal impact
|
||||
|
||||
**2. Provocative Question**
|
||||
- "What if I told you that everything we thought about X is wrong?"
|
||||
- Engages audience immediately, creates curiosity
|
||||
|
||||
**3. Personal Story**
|
||||
- "Five years ago, I encountered a patient/problem that changed how I think about..."
|
||||
- Humanizes research, creates emotional connection
|
||||
|
||||
**4. Visual Puzzle**
|
||||
- Start with an intriguing image or data visualization
|
||||
- "Look at this pattern. What could explain it?"
|
||||
|
||||
**5. Contrasting Paradigms**
|
||||
- "The traditional view says X, but new evidence suggests Y."
|
||||
- Sets up tension and your contribution
|
||||
|
||||
**6. Scope and Scale**
|
||||
- "This problem affects X people, costs Y dollars, and has been unsolved for Z years."
|
||||
- Establishes immediate importance
|
||||
|
||||
### Title Slide Essentials
|
||||
|
||||
Your title slide should include:
|
||||
- **Clear, specific title** (not generic)
|
||||
- **Your name and credentials**
|
||||
- **Affiliation(s) with logos**
|
||||
- **Date and venue** (conference name)
|
||||
- **Optional**: QR code to paper, slides, or resources
|
||||
- **Optional**: Compelling background image related to research
|
||||
|
||||
**Title Crafting**:
|
||||
- Be specific: "Machine Learning Predicts Alzheimer's Risk from Retinal Images"
|
||||
- Not vague: "Applications of AI in Healthcare"
|
||||
- Include key method and outcome
|
||||
- Maximum 15 words
|
||||
- Avoid jargon if presenting to broader audience
|
||||
|
||||
### Outline Slides
|
||||
|
||||
For talks >20 minutes, include a brief outline slide:
|
||||
- Shows 3-5 main sections
|
||||
- Provides roadmap for audience
|
||||
- Can return to outline as section dividers
|
||||
- Keep simple and visual (not just bullet list)
|
||||
|
||||
Example outline approach:
|
||||
```
|
||||
[Icon] Background → [Icon] Methods → [Icon] Results → [Icon] Implications
|
||||
```
|
||||
|
||||
## Closing Strategies
|
||||
|
||||
### Effective Conclusions
|
||||
|
||||
The last 1-2 minutes are most remembered. Strong conclusions:
|
||||
|
||||
**1. Key Takeaways Format**
|
||||
- 3-5 bullet points summarizing main messages
|
||||
- Each should be a complete, memorable sentence
|
||||
- Not just "Results": make claims
|
||||
|
||||
**2. Call-Back Hook**
|
||||
- Reference your opening hook or question
|
||||
- "Remember that surprising statistic? Our findings suggest..."
|
||||
- Creates narrative closure
|
||||
|
||||
**3. Practical Implications**
|
||||
- "What does this mean for clinicians/researchers/policy?"
|
||||
- Action-oriented takeaways
|
||||
- Bridges science to application
|
||||
|
||||
**4. Visual Summary**
|
||||
- Single powerful figure integrating all findings
|
||||
- Conceptual model showing relationships
|
||||
- Before/after comparison
|
||||
|
||||
**5. Future Outlook**
|
||||
- "These findings open doors to..."
|
||||
- 1-2 specific next steps
|
||||
- Inspiration for audience's own work
|
||||
|
||||
### Acknowledgments Slide
|
||||
|
||||
Essential elements:
|
||||
- **Funding sources** (with grant numbers)
|
||||
- **Key collaborators** (with photos if space)
|
||||
- **Institution/lab** (with logo)
|
||||
- **Study participants** (appropriate mention)
|
||||
- Keep brief (15-30 seconds max)
|
||||
- Optional: Include contact info and QR codes here
|
||||
|
||||
### Final Slide
|
||||
|
||||
Your final slide stays visible during Q&A. Include:
|
||||
- **"Thank you" or "Questions?"**
|
||||
- **Your contact information** (email, Twitter/X)
|
||||
- **QR code to paper, preprint, or slides**
|
||||
- **Lab website or GitHub**
|
||||
- **Key visual from your research** (not just text)
|
||||
|
||||
Avoid ending with "References" or dense acknowledgments—these don't facilitate discussion.
|
||||
|
||||
## Transition Techniques
|
||||
|
||||
Smooth transitions maintain narrative flow and audience orientation.
|
||||
|
||||
### Between Major Sections
|
||||
|
||||
**Explicit Transition Slides**:
|
||||
- Use consistent visual style (color, icon, position)
|
||||
- Single word or short phrase: "Methods" "Results" "Implications"
|
||||
- Optional: Return to outline with current section highlighted
|
||||
|
||||
**Verbal Transitions**:
|
||||
- "Now that we've established X, let's examine how we studied Y..."
|
||||
- "With that background, I'll turn to our key findings..."
|
||||
- "This raises the question: How did we measure this?"
|
||||
|
||||
### Between Related Slides
|
||||
|
||||
**Visual Continuity**:
|
||||
- Repeat key element (figure, title format) across slides
|
||||
- Use consistent color coding
|
||||
- Progressive builds of same figure
|
||||
|
||||
**Verbal Bridges**:
|
||||
- "Building on this finding..."
|
||||
- "To test this further..."
|
||||
- "This pattern was consistent across..."
|
||||
|
||||
### Signposting Language
|
||||
|
||||
Help audience track progress through talk:
|
||||
- "First, I'll show... Second... Finally..."
|
||||
- "There are three key findings to discuss..."
|
||||
- "Now, let's turn to the most surprising result..."
|
||||
- "Coming back to our original question..."
|
||||
|
||||
## Pacing and Timing
|
||||
|
||||
### Time Budgeting
|
||||
|
||||
**Plan timing for each slide**:
|
||||
- Simple title/transition slides: 15-30 seconds
|
||||
- Text content slides: 45-90 seconds
|
||||
- Complex figures: 2-3 minutes
|
||||
- Key results: 2-4 minutes each
|
||||
|
||||
**Common Timing Mistakes**:
|
||||
- ❌ Spending too long on introduction (>15% of talk)
|
||||
- ❌ Rushing through results (should be 40-50%)
|
||||
- ❌ Not leaving time for questions
|
||||
- ❌ Going over time (extremely unprofessional)
|
||||
|
||||
### Practice Strategies
|
||||
|
||||
**Full Run-Throughs** (Do 3-5 times):
|
||||
1. **First run**: Rough timing, identify problem areas
|
||||
2. **Second run**: Practice transitions, smooth language
|
||||
3. **Third run**: Final timing with backup plans
|
||||
4. **Recording**: Video yourself, watch for tics/filler words
|
||||
5. **Audience practice**: Present to colleagues for feedback
|
||||
|
||||
**Section Practice**:
|
||||
- Practice complex result slides multiple times
|
||||
- Rehearse opening and closing until flawless
|
||||
- Prepare ad-libs for common questions
|
||||
|
||||
**Timing Techniques**:
|
||||
- Note target time at bottom of key slides
|
||||
- Set phone/watch to vibrate at checkpoints
|
||||
- Have Plan B: know which slides to skip if running over
|
||||
- Practice with live timer visible
|
||||
|
||||
### Managing Time During Talk
|
||||
|
||||
**If Running Ahead** (rarely a problem):
|
||||
- Expand on key points naturally
|
||||
- Take questions mid-talk if appropriate
|
||||
- Provide more context or examples
|
||||
- Slow down slightly (but don't add filler)
|
||||
|
||||
**If Running Behind**:
|
||||
- Skip backup slides or extra examples (prepare these in advance)
|
||||
- Summarize rather than detail on secondary points
|
||||
- Never rush through conclusions—skip earlier content instead
|
||||
- NEVER say "I'll go quickly through these" (just skip them)
|
||||
|
||||
**Time Checkpoints**:
|
||||
- 25% through talk = 25% through time
|
||||
- 50% through talk = 50% through time
|
||||
- After results = should have 5-10 minutes left
|
||||
- Start conclusions with 2-3 minutes remaining
|
||||
|
||||
## Audience Engagement
|
||||
|
||||
### Reading the Room
|
||||
|
||||
**Visual Cues**:
|
||||
- **Engaged**: Leaning forward, nodding, taking notes
|
||||
- **Lost**: Confused expressions, checking phones
|
||||
- **Bored**: Leaning back, glazed eyes, fidgeting
|
||||
|
||||
**Adjustments**:
|
||||
- If losing audience: Speed up, add humor, show compelling visual
|
||||
- If audience confused: Slow down, ask "Does this make sense?", re-explain
|
||||
- If highly engaged: Can add more detail, encourage questions
|
||||
|
||||
### Interactive Elements
|
||||
|
||||
For seminars and longer talks:
|
||||
|
||||
**Rhetorical Questions**:
|
||||
- "Why do you think this pattern occurred?"
|
||||
- "What would you predict happens next?"
|
||||
- Pauses for thought (don't immediately answer)
|
||||
|
||||
**Quick Polls** (if appropriate):
|
||||
- "Raise your hand if you've encountered X..."
|
||||
- "How many think the result will be A vs. B?"
|
||||
- Brief, not disruptive
|
||||
|
||||
**Checkpoint Questions**:
|
||||
- "Before I continue, are there questions about the methods?"
|
||||
- "Is everyone comfortable with this concept?"
|
||||
- For longer talks or tutorials
|
||||
|
||||
### Body Language and Delivery
|
||||
|
||||
**Effective Practices**:
|
||||
- ✅ Stand to side of screen, facing audience
|
||||
- ✅ Use pointer deliberately for specific elements
|
||||
- ✅ Make eye contact with different sections of room
|
||||
- ✅ Gesture naturally to emphasize points
|
||||
- ✅ Vary voice pitch and pace
|
||||
- ✅ Pause after important points
|
||||
|
||||
**Avoid**:
|
||||
- ❌ Reading slides verbatim
|
||||
- ❌ Turning back to audience
|
||||
- ❌ Standing in front of projection
|
||||
- ❌ Fidgeting with pointer/objects
|
||||
- ❌ Pacing repetitively
|
||||
- ❌ Monotone delivery
|
||||
|
||||
## Special Considerations
|
||||
|
||||
### Virtual Presentations
|
||||
|
||||
**Technical Setup**:
|
||||
- Test screen sharing, audio, and video beforehand
|
||||
- Use presenter mode if available (see notes)
|
||||
- Ensure good lighting and camera angle
|
||||
- Minimize background distractions
|
||||
|
||||
**Engagement Challenges**:
|
||||
- Can't read audience body language as well
|
||||
- More explicit engagement needed
|
||||
- Use polls, chat, reactions if platform allows
|
||||
- Encourage unmuting for questions
|
||||
|
||||
**Pacing**:
|
||||
- Slightly slower pace (harder to interrupt virtually)
|
||||
- More explicit transitions and signposting
|
||||
- Build in planned pauses for questions
|
||||
- Monitor chat for questions during talk
|
||||
|
||||
### Handling Questions
|
||||
|
||||
**During Talk**:
|
||||
- For short talks: "Please hold questions until the end"
|
||||
- For seminars: "Feel free to interrupt with questions"
|
||||
- If interrupted: "Great question, let me finish this point and come back to it"
|
||||
|
||||
**Q&A Session**:
|
||||
- **Listen fully** before answering
|
||||
- **Repeat or rephrase** question for whole audience
|
||||
- **Answer concisely** (30-90 seconds max)
|
||||
- **Be honest** if you don't know: "That's a great question I don't have data on yet"
|
||||
- **Redirect if off-topic**: "That's interesting but beyond scope. Happy to discuss after."
|
||||
- **Have backup slides** with extra data/analyses ready
|
||||
|
||||
**Difficult Questions**:
|
||||
- **Hostile**: Stay calm, acknowledge concern, stick to data
|
||||
- **Confusing**: Ask for clarification: "Could you rephrase that?"
|
||||
- **Out of scope**: "I focused on X, but your question about Y is important for future work"
|
||||
|
||||
### Technical Difficulties
|
||||
|
||||
**Preparation**:
|
||||
- Have backup: PDF on laptop, cloud, and USB drive
|
||||
- Test connections and adapters beforehand
|
||||
- Know how to reset display if needed
|
||||
- Have printout of slides as absolute backup
|
||||
|
||||
**During Talk**:
|
||||
- Stay calm and professional
|
||||
- Fill time with verbal explanation while fixing
|
||||
- Skip problem slide if necessary
|
||||
- Apologize briefly but don't dwell on it
|
||||
|
||||

# Slide Design Principles for Scientific Presentations
|
||||
|
||||
## Overview
|
||||
|
||||
Effective slide design enhances comprehension, maintains audience attention, and ensures your scientific message is communicated clearly. This guide covers visual hierarchy, typography, color theory, layout principles, and accessibility considerations for creating professional scientific presentations.
|
||||
|
||||
## Core Design Principles
|
||||
|
||||
### 1. Simplicity and Clarity
|
||||
|
||||
**The Fundamental Rule**: Each slide should communicate ONE main idea.
|
||||
|
||||
**Why It Matters**:
|
||||
- Audiences can only process limited information at once
|
||||
- Complexity causes cognitive overload
|
||||
- Simple slides are remembered; busy slides are forgotten
|
||||
|
||||
**Application**:
|
||||
- ✅ One message per slide
|
||||
- ✅ Minimal text (audiences read OR listen, not both simultaneously)
|
||||
- ✅ Clear visual focus
|
||||
- ✅ Generous white space
|
||||
- ❌ Avoid cramming multiple concepts onto one slide
|
||||
|
||||
**Example Comparison**:
|
||||
```
|
||||
BAD: Single slide with:
|
||||
- 3 different graphs
|
||||
- 8 bullet points
|
||||
- 2 tables
|
||||
- Dense caption text
|
||||
|
||||
GOOD: Three separate slides:
|
||||
- Slide 1: First graph with 2-3 key points
|
||||
- Slide 2: Second graph with interpretation
|
||||
- Slide 3: Summary table with highlighted finding
|
||||
```
|
||||
|
||||
### 2. Visual Hierarchy
|
||||
|
||||
Guide attention to the most important elements through size, color, and position.
|
||||
|
||||
**Hierarchy Levels**:
|
||||
1. **Primary**: Main message or key data (largest, highest contrast)
|
||||
2. **Secondary**: Supporting information (medium size)
|
||||
3. **Tertiary**: Details and labels (smaller, lower contrast)
|
||||
|
||||
**Techniques**:
|
||||
|
||||
**Size**:
|
||||
- Title: Largest (36-54pt)
|
||||
- Key findings: Large (24-32pt)
|
||||
- Supporting text: Medium (18-24pt)
|
||||
- Labels and notes: Smallest but legible (14-18pt)
|
||||
|
||||
**Color**:
|
||||
- High contrast for key elements
|
||||
- Accent colors for emphasis
|
||||
- Muted colors for background or secondary info
|
||||
|
||||
**Position**:
|
||||
- Top-left or top-center: Primary content (Western reading pattern)
|
||||
- Center: Focal point for key visuals
|
||||
- Bottom or sides: Supporting details
|
||||
|
||||
**Weight**:
|
||||
- Bold for emphasis on key terms
|
||||
- Regular weight for body text
|
||||
- Light weight for de-emphasized content
|
||||
|
||||
### 3. Consistency
|
||||
|
||||
Maintain visual consistency throughout the presentation.
|
||||
|
||||
**Elements to Keep Consistent**:
|
||||
- **Fonts**: Same font family for all slides
|
||||
- **Colors**: Defined color palette (3-5 colors)
|
||||
- **Layouts**: Similar slides use same structure
|
||||
- **Spacing**: Margins and padding uniform
|
||||
- **Style**: Figure formats, bullet styles, numbering
|
||||
|
||||
**Benefits**:
|
||||
- Professional appearance
|
||||
- Reduced cognitive load (audiences learn your visual language)
|
||||
- Focus on content, not adjusting to new formats
|
||||
- Easy to identify information types
|
||||
|
||||
**Template Approach**:
|
||||
- Create master slide with standard elements
|
||||
- Design 3-5 layout variants (title, content, figure, section divider)
|
||||
- Apply consistently throughout
|
||||
|
||||
## Typography
|
||||
|
||||
### Font Selection
|
||||
|
||||
**Recommended Font Types**:
|
||||
|
||||
**Sans-Serif Fonts** (Highly Recommended):
|
||||
- **Arial**: Universal, highly legible
|
||||
- **Helvetica**: Clean, professional
|
||||
- **Calibri**: Modern default, works well
|
||||
- **Gill Sans**: Elegant sans-serif
|
||||
- **Futura**: Geometric, modern
|
||||
- **Avenir**: Friendly, professional
|
||||
|
||||
**Serif Fonts** (Use Sparingly):
|
||||
- Generally harder to read on screens
|
||||
- Acceptable for titles in some contexts
|
||||
- Avoid for body text in presentations
|
||||
|
||||
**Avoid**:
|
||||
- ❌ Script or handwriting fonts (illegible from distance)
|
||||
- ❌ Decorative fonts (distracting)
|
||||
- ❌ Condensed fonts (hard to read)
|
||||
- ❌ Multiple font families (>2 looks unprofessional)
|
||||
|
||||
### Font Sizes
|
||||
|
||||
**Minimum Readable Sizes**:
|
||||
- **Title slide title**: 44-54pt
|
||||
- **Section headers**: 36-44pt
|
||||
- **Slide titles**: 32-40pt
|
||||
- **Body text**: 24-28pt (absolute minimum 18pt)
|
||||
- **Figure labels**: 18-24pt
|
||||
- **Captions and citations**: 14-16pt (use sparingly)
|
||||
|
||||
**The Room Test**:
|
||||
- Can text be read from the back of the room?
|
||||
- Rule: Body text should be readable at 6× screen height distance
|
||||
- When in doubt: go larger
|
||||
|
||||
**Size Relationships**:
|
||||
```
|
||||
Title: 40pt
|
||||
━━━━━━━━━━━━━━━━━
|
||||
Subheading: 28pt
|
||||
─────────────
|
||||
Body text: 24pt
|
||||
Regular content for audience
|
||||
|
||||
Caption: 16pt
|
||||
```
|
||||
|
||||
### Text Formatting
|
||||
|
||||
**Best Practices**:
|
||||
|
||||
**Line Length**:
|
||||
- Maximum 50-60 characters per line
|
||||
- Break long sentences into multiple lines
|
||||
- Use phrases, not full sentences when possible
|
||||
|
||||
**Line Spacing**:
|
||||
- 1.2-1.5× line height for readability
|
||||
- More spacing for dense content
|
||||
- Consistent spacing throughout
|
||||
|
||||
**Alignment**:
|
||||
- **Left-aligned**: Best for body text (natural reading)
|
||||
- **Center-aligned**: Titles, short phrases, key messages
|
||||
- **Right-aligned**: Rarely used (occasionally for design balance)
|
||||
- **Justified**: Avoid (creates awkward spacing)
|
||||
|
||||
**Emphasis**:
|
||||
- ✅ **Bold** for key terms (use sparingly)
|
||||
- ✅ Color for emphasis (consistent meaning)
|
||||
- ✅ Size increase for importance
|
||||
- ❌ Avoid italics (hard to read from distance)
|
||||
- ❌ Avoid underline (confused with hyperlinks)
|
||||
- ❌ AVOID ALL CAPS FOR BODY TEXT (READS AS SHOUTING)
|
||||
|
||||
### The 6×6 Rule
|
||||
|
||||
**Guideline**: Maximum 6 bullets per slide, maximum 6 words per bullet.
|
||||
|
||||
**Rationale**:
|
||||
- More text = audience reads instead of listens
|
||||
- Bullet points are prompts, not sentences
|
||||
- You provide the explanation verbally
|
||||
|
||||
**Better Approach**:
|
||||
- 3-4 bullets optimal
|
||||
- 4-8 words per bullet
|
||||
- Use fragments, not complete sentences
|
||||
- Consider replacing text with visuals
|
||||
|
||||
**Example Transformation**:
|
||||
```
|
||||
TOO MUCH TEXT:
|
||||
• Our study examined the relationship between dietary interventions
|
||||
and cardiovascular outcomes in 1,500 participants over 5 years
|
||||
• We found that participants in the intervention group showed
|
||||
significantly reduced risk compared to controls
|
||||
• The effect size was larger than previous studies and persisted
|
||||
at long-term follow-up
|
||||
|
||||
BETTER:
|
||||
• 5-year dietary intervention study
|
||||
• 27% reduced cardiovascular risk
|
||||
• Largest effect to date
|
||||
```
|
||||
|
||||
## Color Theory
|
||||
|
||||
### Color Palettes for Scientific Presentations
|
||||
|
||||
**Purpose-Driven Color Selection**:
|
||||
|
||||
**Professional/Academic** (Conservative):
|
||||
- Navy blue (#1C3D5A), gray (#4A5568), white (#FFFFFF)
|
||||
- Accent: Orange (#E67E22) or green (#27AE60)
|
||||
- Use: Faculty seminars, grant presentations, institutional talks
|
||||
|
||||
**Modern/Engaging** (Energetic):
|
||||
- Teal (#0A9396), coral (#EE6C4D), cream (#F4F1DE)
|
||||
- Accent: Burgundy (#780000)
|
||||
- Use: Conference talks, public engagement, TED-style talks
|
||||
|
||||
**High Contrast** (Maximum Legibility):
|
||||
- Black text (#000000) on white (#FFFFFF)
|
||||
- Dark blue (#003366) on white
|
||||
- White on dark gray (#2D3748)
|
||||
- Use: Large venues, virtual presentations, accessibility priority
|
||||
|
||||
**Data Visualization** (Color-blind Safe):
|
||||
- Blue (#0173B2), orange (#DE8F05), green (#029E73), red (#CC78BC)
|
||||
- Based on Wong/IBM palettes
|
||||
- Use: Figures with categorical data, bar charts, line plots
|
||||
|
||||
### Color Psychology in Science
|
||||
|
||||
**Blue**:
|
||||
- Associations: Trust, stability, professionalism, intelligence
|
||||
- Use: Backgrounds, institutional presentations, technology topics
|
||||
- Caution: Can feel cold; balance with warmer accents
|
||||
|
||||
**Green**:
|
||||
- Associations: Growth, health, nature, sustainability
|
||||
- Use: Biology, environmental science, health outcomes
|
||||
- Caution: Avoid red-green combinations (color blindness)
|
||||
|
||||
**Red/Orange**:
|
||||
- Associations: Energy, urgency, warning, importance
|
||||
- Use: Highlighting critical findings, emphasis, calls to action
|
||||
- Caution: Don't overuse; loses impact
|
||||
|
||||
**Purple**:
|
||||
- Associations: Innovation, creativity, wisdom
|
||||
- Use: Neuroscience, novel methods, creative research
|
||||
- Caution: Can appear less serious in some contexts
|
||||
|
||||
**Gray**:
|
||||
- Associations: Neutrality, professionalism, sophistication
|
||||
- Use: Backgrounds, de-emphasized content, grounding
|
||||
- Caution: Can feel dull if overused
|
||||
|
||||
### Color Contrast and Accessibility
|
||||
|
||||
**WCAG Standards** (Web Content Accessibility Guidelines):
|
||||
- **Level AA**: 4.5:1 contrast ratio for normal text
|
||||
- **Level AAA**: 7:1 contrast ratio (preferred for presentations)
|
||||
|
||||
**High Contrast Combinations**:
|
||||
- ✅ Black on white (21:1)
|
||||
- ✅ Dark blue (#003366) on white (12.6:1)
|
||||
- ✅ White on dark gray (#2D3748) (11.8:1)
|
||||
- ✅ Dark text (#333333) on cream (#F4F1DE) (9.7:1)
|
||||
|
||||
**Low Contrast Combinations** (Avoid):
|
||||
- ❌ Light gray on white
|
||||
- ❌ Yellow on white
|
||||
- ❌ Pastel colors on white backgrounds
|
||||
- ❌ Red on black (difficult to read)
|
||||
|
||||
**Testing Contrast**:
|
||||
- Use online tools (e.g., WebAIM Contrast Checker)
|
||||
- Print slide in grayscale (should remain legible)
|
||||
- View from distance (simulate audience perspective)
|
||||
|
||||
### Color Blindness Considerations
|
||||
|
||||
**Prevalence**: ~8% of men, ~0.5% of women have color vision deficiency
|
||||
|
||||
**Most Common**: Red-green color blindness (protanopia/deuteranopia)
|
||||
|
||||
**Safe Practices**:
|
||||
- ✅ Use blue/orange instead of red/green
|
||||
- ✅ Add patterns or shapes in addition to color
|
||||
- ✅ Use color AND other differentiators (shape, size, position)
|
||||
- ✅ Test with color blindness simulator
|
||||
|
||||
**Color-Blind Safe Palettes**:
|
||||
```
|
||||
Primary: Blue (#0173B2)
|
||||
Contrast: Orange (#DE8F05) [NOT green]
|
||||
Additional: Magenta (#CC78BC), Teal (#029E73)
|
||||
```
|
||||
|
||||
**Figure Design**:
|
||||
- Don't rely solely on red vs. green lines
|
||||
- Use different line styles (solid, dashed, dotted)
|
||||
- Use symbols (circle, square, triangle) for scatter plots
|
||||
- Label directly on plot rather than color legend only
|
||||
|
||||
## Layout and Composition
|
||||
|
||||
### The Rule of Thirds
|
||||
|
||||
Divide slide into 3×3 grid; place key elements at intersections or along lines.
|
||||
|
||||
**Application**:
|
||||
```
|
||||
+-------+-------+-------+
|
||||
| ┃ | ┃ | ┃ |
|
||||
|---●---|---●---|---●---| ← Key focal points (●)
|
||||
| ┃ | ┃ | ┃ |
|
||||
|---●---|---●---|---●---|
|
||||
| ┃ | ┃ | ┃ |
|
||||
|---●---|---●---|---●---|
|
||||
| ┃ | ┃ | ┃ |
|
||||
+-------+-------+-------+
|
||||
```
|
||||
|
||||
**Benefits**:
|
||||
- More visually interesting than centered layouts
|
||||
- Natural eye flow
|
||||
- Professional appearance
|
||||
- Guides attention strategically
|
||||
|
||||
**Example Usage**:
|
||||
- Place key figure at right third
|
||||
- Text summary on left two-thirds
|
||||
- Title at top third line
|
||||
- Logo at bottom-right intersection
|
||||
|
||||
### White Space
|
||||
|
||||
**Definition**: Empty space around and between elements.
|
||||
|
||||
**Purpose**:
|
||||
- Gives content room to "breathe"
|
||||
- Increases focus on important elements
|
||||
- Prevents overwhelming the audience
|
||||
- Projects professionalism and confidence
|
||||
|
||||
**Guidelines**:
|
||||
- Margins: Minimum 5-10% of slide on all sides
|
||||
- Element spacing: Clear separation between unrelated items
|
||||
- Text padding: Space around text blocks
|
||||
- Don't fill every pixel: Empty space is valuable
|
||||
|
||||
**Common Mistakes**:
|
||||
- Cramming too much on one slide
|
||||
- Extending content to edges
|
||||
- No space between elements
|
||||
- Fear of "wasting" space
|
||||
|
||||
### Layout Patterns
|
||||
|
||||
**Title + Content**:
|
||||
```
|
||||
┌─────────────────────────┐
|
||||
│ Slide Title │
|
||||
├─────────────────────────┤
|
||||
│ │
|
||||
│ Content Area │
|
||||
│ (text, figure, │
|
||||
│ or combination) │
|
||||
│ │
|
||||
└─────────────────────────┘
|
||||
```
|
||||
Use: Standard slide type, most common
|
||||
|
||||
**Two Column**:
|
||||
```
|
||||
┌─────────────────────────┐
|
||||
│ Slide Title │
|
||||
├───────────┬─────────────┤
|
||||
│ │ │
|
||||
│ Text │ Figure │
|
||||
│ Column │ Column │
|
||||
│ │ │
|
||||
└───────────┴─────────────┘
|
||||
```
|
||||
Use: Comparing items, text + figure
|
||||
|
||||
**Full-Slide Figure**:
|
||||
```
|
||||
┌─────────────────────────┐
|
||||
│ │
|
||||
│ │
|
||||
│ Large Figure or │
|
||||
│ Image │
|
||||
│ │
|
||||
│ │
|
||||
└─────────────────────────┘
|
||||
```
|
||||
Use: Key results, impactful visuals
|
||||
|
||||
**Text Overlay**:
|
||||
```
|
||||
┌─────────────────────────┐
|
||||
│ ┌─────────────┐ │
|
||||
│ │ Text Box │ │
|
||||
│ └─────────────┘ │
|
||||
│ Background Image │
|
||||
│ │
|
||||
└─────────────────────────┘
|
||||
```
|
||||
Use: Title slide, section dividers
|
||||
|
||||
**Grid Layout**:
|
||||
```
|
||||
┌─────────────────────────┐
|
||||
│ Title │
|
||||
├─────────┬───────┬───────┤
|
||||
│ Item 1 │ Item 2│ Item 3│
|
||||
├─────────┼───────┼───────┤
|
||||
│ Item 4 │ Item 5│ Item 6│
|
||||
└─────────┴───────┴───────┘
|
||||
```
|
||||
Use: Multiple related items, comparisons
|
||||
|
||||
### Alignment
|
||||
|
||||
**Principle**: Align elements to create visual order and relationships.
|
||||
|
||||
**Types**:
|
||||
|
||||
**Edge Alignment**:
|
||||
- Align left edges of text blocks
|
||||
- Align right edges of figures
|
||||
- Align top edges of items in row
|
||||
|
||||
**Center Alignment**:
|
||||
- Center title on slide
|
||||
- Center key messages
|
||||
- Center lone figures
|
||||
|
||||
**Grid Alignment**:
|
||||
- Use invisible grid
|
||||
- Snap elements to grid lines
|
||||
- Maintains consistency across slides
|
||||
|
||||
**Visual Impact**:
|
||||
- Aligned elements look intentional and professional
|
||||
- Misaligned elements appear careless
|
||||
- Small misalignments are very noticeable
|
||||
|
||||
## Background Design
|
||||
|
||||
### Background Colors
|
||||
|
||||
**Best Practices**:
|
||||
|
||||
**Light Backgrounds** (Most Common):
|
||||
- White or off-white (#FFFFFF, #F8F9FA)
|
||||
- Very light gray (#F5F5F5)
|
||||
- Cream/beige (#FAF8F3)
|
||||
|
||||
**Advantages**:
|
||||
- Maximum contrast for dark text
|
||||
- Works in any lighting
|
||||
- Professional and clean
|
||||
- Easier on projectors
|
||||
|
||||
**Dark Backgrounds**:
|
||||
- Dark gray (#2D3748)
|
||||
- Navy blue (#1A202C)
|
||||
- Black (#000000)
|
||||
|
||||
**Advantages**:
|
||||
- Modern, sophisticated
|
||||
- Good for dark venues
|
||||
- Reduces eye strain in dark rooms
|
||||
- Makes colors pop
|
||||
|
||||
**Disadvantages**:
|
||||
- Requires light-colored text
|
||||
- Can be difficult in bright rooms
|
||||
- Some projectors handle poorly
|
||||
|
||||
**Gradient Backgrounds**:
|
||||
- ✅ Subtle gradients acceptable (light to lighter)
|
||||
- ❌ Avoid busy or high-contrast gradients
|
||||
- ❌ Don't distract from content
|
||||
|
||||
**Image Backgrounds**:
|
||||
- Use only for title/section slides
|
||||
- Ensure sufficient contrast with text
|
||||
- Add semi-transparent overlay if needed
|
||||
- Avoid busy or cluttered images
|
||||
|
||||
### Borders and Frames
|
||||
|
||||
**Minimal Approach** (Recommended):
|
||||
- No borders on most slides
|
||||
- Let white space define boundaries
|
||||
- Clean, modern appearance
|
||||
|
||||
**Selective Borders**:
|
||||
- Around key figures for emphasis
|
||||
- Separating distinct sections
|
||||
- Highlighting callout boxes
|
||||
- Simple, thin lines only
|
||||
|
||||
**Avoid**:
|
||||
- Decorative borders
|
||||
- Thick, colorful frames
|
||||
- Clipart-style elements
|
||||
- 3D effects and shadows
|
||||
|
||||
## Visual Elements
|
||||
|
||||
### Icons and Graphics
|
||||
|
||||
**Purpose**:
|
||||
- Visual anchors for concepts
|
||||
- Break up text-heavy slides
|
||||
- Quick recognition of section types
|
||||
- Add visual interest
|
||||
|
||||
**Best Practices**:
|
||||
- ✅ Consistent style (all outline or all filled)
|
||||
- ✅ Simple, recognizable designs
|
||||
- ✅ Appropriate size (not too large or small)
|
||||
- ✅ Limited color palette matching theme
|
||||
- ❌ Avoid clipart or cartoonish graphics (unless appropriate)
|
||||
- ❌ Don't use for decoration only (should convey meaning)
|
||||
|
||||
**Sources**:
|
||||
- Font Awesome
|
||||
- Noun Project
|
||||
- Material Design Icons
|
||||
- Custom scientific illustrations
|
||||
|
||||
### Bullets and Lists
|
||||
|
||||
**Bullet Styles**:
|
||||
- **Simple shapes**: Circle (•), square (■), dash (−)
|
||||
- **Avoid**: Complex symbols, changing bullet styles within list
|
||||
- **Hierarchy**: Different bullets for different levels
|
||||
|
||||
**List Best Practices**:
|
||||
- Maximum 4-6 items per list
|
||||
- Parallel structure (all start with verb, or all nouns, etc.)
|
||||
- Use fragments, not complete sentences
|
||||
- Adequate spacing between items (1.5-2× line height)
|
||||
|
||||
**Alternative to Bullets**:
|
||||
- **Numbered lists**: When order matters
|
||||
- **Icons**: Visual representation of each point
|
||||
- **Progressive builds**: Reveal one point at a time
|
||||
- **Separate slides**: One concept per slide
|
||||
|
||||
### Shapes and Dividers
|
||||
|
||||
**Uses**:
|
||||
- Background rectangles to highlight content
|
||||
- Arrows showing relationships or flow
|
||||
- Circles for emphasis or grouping
|
||||
- Lines separating sections
|
||||
|
||||
**Guidelines**:
|
||||
- Keep shapes simple (rectangles, circles, lines)
|
||||
- Use brand colors
|
||||
- Maintain consistency
|
||||
- Avoid 3D effects
|
||||
- Don't overuse
|
||||
|
||||
## Animation and Builds
|
||||
|
||||
### When to Use Animation
|
||||
|
||||
**Appropriate Uses**:
|
||||
- **Progressive disclosure**: Reveal bullet points one at a time
|
||||
- **Build complex figures**: Add layers incrementally
|
||||
- **Show process**: Illustrate sequential steps
|
||||
- **Emphasize transitions**: Highlight connections
|
||||
- **Control pacing**: Prevent audience from reading ahead
|
||||
|
||||
**Inappropriate Uses**:
|
||||
- ❌ Decoration or entertainment
|
||||
- ❌ Every slide transition
|
||||
- ❌ Multiple animations per slide
|
||||
- ❌ Distracting effects (spin, bounce, etc.)
|
||||
|
||||
### Types of Animations
|
||||
|
||||
**Entrance**:
|
||||
- **Appear**: Instant (good for fast-paced talks)
|
||||
- **Fade**: Subtle, professional
|
||||
- **Wipe**: Directional reveal
|
||||
- Avoid: Fly in, bounce, spiral, etc.
|
||||
|
||||
**Exit**:
|
||||
- Rarely needed
|
||||
- Use to remove intermediary steps
|
||||
- Keep simple (fade or disappear)
|
||||
|
||||
**Emphasis**:
|
||||
- Color change for highlighting
|
||||
- Bold/underline to draw attention
|
||||
- Grow slightly for importance
|
||||
- Use very sparingly
|
||||
|
||||
**Builds**:
|
||||
- Reveal bullet points progressively
|
||||
- Add elements to complex figure
|
||||
- Show before/after states
|
||||
- Demonstrate process steps
|
||||
|
||||
**Best Practices**:
|
||||
- Fast transitions (0.2-0.3 seconds)
|
||||
- Consistent animation type throughout
|
||||
- Click to advance (not automatic timing)
|
||||
- Builds should add clarity, not complexity
|
||||
|
||||
## Common Design Mistakes
|
||||
|
||||
### Content Mistakes
|
||||
|
||||
**Too Much Text**:
|
||||
- Problem: Audience reads instead of listening
|
||||
- Fix: Use key phrases, not paragraphs; move details to notes
|
||||
|
||||
**Too Many Concepts per Slide**:
|
||||
- Problem: Cognitive overload, unclear focus
|
||||
- Fix: One idea per slide; split complex slides into multiple
|
||||
|
||||
**Inconsistent Formatting**:
|
||||
- Problem: Looks unprofessional, distracting
|
||||
- Fix: Use templates, maintain style guide
|
||||
|
||||
**Poor Contrast**:
|
||||
- Problem: Illegible from distance
|
||||
- Fix: Test at actual presentation size, use high-contrast combinations
|
||||
|
||||
**Tiny Fonts**:
|
||||
- Problem: Unreadable for audience
|
||||
- Fix: Minimum 18pt, preferably 24pt+ for body text
|
||||
|
||||
### Visual Mistakes
|
||||
|
||||
**Cluttered Slides**:
|
||||
- Problem: No clear focal point, overwhelming
|
||||
- Fix: Embrace white space, remove non-essential elements
|
||||
|
||||
**Low-Quality Images**:
|
||||
- Problem: Pixelated or blurry figures
|
||||
- Fix: Use high-resolution images (300 DPI minimum)
|
||||
|
||||
**Distracting Backgrounds**:
|
||||
- Problem: Competes with content
|
||||
- Fix: Simple, solid colors or subtle gradients
|
||||
|
||||
**Overuse of Effects**:
|
||||
- Problem: Looks amateurish, distracting
|
||||
- Fix: Minimal or no shadows, gradients, 3D effects
|
||||
|
||||
**Misaligned Elements**:
|
||||
- Problem: Appears careless
|
||||
- Fix: Use alignment tools, grids, and guides
|
||||
|
||||
### Color Mistakes
|
||||
|
||||
**Insufficient Contrast**:
|
||||
- Problem: Hard to read
|
||||
- Fix: Test with contrast checker, use dark on light or light on dark
|
||||
|
||||
**Too Many Colors**:
|
||||
- Problem: Chaotic, unprofessional
|
||||
- Fix: Limit to 3-5 colors total
|
||||
|
||||
**Red-Green Combinations**:
|
||||
- Problem: Invisible to color-blind audience members
|
||||
- Fix: Use blue-orange or add patterns/shapes
|
||||
|
||||
**Clashing Colors**:
|
||||
- Problem: Visually jarring
|
||||
- Fix: Use color palette tools, test combinations
|
||||
|
||||
## Accessibility
|
||||
|
||||
### Designing for All Audiences
|
||||
|
||||
**Visual Impairments**:
|
||||
- High contrast text (minimum 4.5:1, preferably 7:1)
|
||||
- Large fonts (minimum 18pt, prefer 24pt+)
|
||||
- Simple, clear fonts
|
||||
- No reliance on color alone to convey meaning
|
||||
|
||||
**Color Blindness**:
|
||||
- Avoid red-green combinations
|
||||
- Use patterns, shapes, or labels in addition to color

||||
- Readable on different screens (laptop, projector, phone)
|
||||
- Printable in grayscale if needed
|
||||
|
||||
### Alternative Text and Descriptions
|
||||
|
||||
**For Figures**:
|
||||
- Provide verbal description during talk
|
||||
- Include detailed caption in notes
|
||||
- Describe key patterns: "Notice the increasing trend..."
|
||||
|
||||
**For Complex Visuals**:
|
||||
- Break into components
|
||||
- Use progressive builds
|
||||
- Provide interpretive context
|
||||
|
||||
## Design Workflow
|
||||
|
||||
### Step 1: Define Visual Identity
|
||||
|
||||
Before creating slides:
|
||||
1. **Color palette**: Choose 3-5 colors
|
||||
2. **Fonts**: Select 1-2 font families
|
||||
3. **Style**: Decide on overall aesthetic (minimal, bold, traditional)
|
||||
4. **Templates**: Create master slides for different types
|
||||
|
||||
### Step 2: Create Master Templates
|
||||
|
||||
Design 4-6 slide layouts:

|
||||
3. **Content slide**: Standard text/bullets
|
||||
4. **Figure slide**: Large visual focus
|
||||
5. **Two-column**: Text + figure side-by-side
|
||||
6. **Closing**: Questions, contact, acknowledgments

||||
|
||||
### Step 3: Apply Consistently
|
||||
|
||||
For each slide:
|
||||

||||
- [ ] How much time do I have? (Strictly enforced or flexible?)
|
||||
- [ ] What is the goal? (Inform, persuade, teach, impress?)
|
||||
- [ ] What format is expected? (Formal vs. interactive, Q&A style)
|
||||
- [ ] What will happen afterward? (Q&A, discussion, evaluation, networking)
|

# Visual Review Workflow for Presentations
|
||||
|
||||
## Overview
|
||||
|
||||
Visual review is a critical quality assurance step for presentations, allowing you to identify and fix layout issues, text overflow, element overlap, and design problems before presenting. This guide covers converting presentations to images, systematic visual inspection, common issues, and iterative improvement strategies.
|
||||
|
||||
## ⚠️ CRITICAL RULE: NEVER READ PDF PRESENTATIONS DIRECTLY
|
||||
|
||||
**MANDATORY: Always convert presentation PDFs to images FIRST, then review the images.**
|
||||
|
||||
### Why This Rule Exists
|
||||
|
||||
- **Buffer Overflow Prevention**: Presentation PDFs (especially multi-slide decks) cause "JSON message exceeded maximum buffer size" errors when read directly
|
||||
- **Visual Accuracy**: Images show exactly what the audience will see, including rendering issues
|
||||
- **Performance**: Image-based review is faster and more reliable than PDF text extraction
|
||||
- **Consistency**: Ensures uniform review process for all presentations
|
||||
|
||||
### The ONLY Correct Workflow for Presentations
|
||||
|
||||
1. ✅ Generate PDF from PowerPoint/Beamer source
|
||||
2. ✅ **Convert PDF to images** using pdftoppm or similar tool
|
||||
3. ✅ **Review the image files** systematically
|
||||
4. ✅ Document issues by slide number
|
||||
5. ✅ Fix issues in source files
|
||||
6. ✅ Regenerate PDF and repeat
|
||||
|
||||
### What NOT To Do
|
||||
|
||||
- ❌ NEVER use read_file tool on presentation PDFs
|
||||
- ❌ NEVER attempt to read PDF slides as text
|
||||
- ❌ NEVER skip the image conversion step
|
||||
- ❌ NEVER assume PDF is "small enough" to read directly
|
||||
|
||||
**If you're reviewing a presentation and haven't converted to images yet, STOP and convert first.**
|
||||
|
||||
## Why Visual Review Matters
|
||||
|
||||
### Common Problems Invisible in Source
|
||||
|
||||
**LaTeX Beamer Issues**:
|
||||
- Text overflow from text boxes
|
||||
- Overlapping elements (equations over images)
|
||||
- Poor line breaking
|
||||
- Figures extending beyond slide boundaries
|
||||
- Font size issues at actual resolution
|
||||
|
||||
**PowerPoint Issues**:
|
||||
- Text cut off by shapes or slide edges
|
||||
- Images overlapping with text
|
||||
- Inconsistent spacing between slides
|
||||
- Color rendering differences
|
||||
- Font substitution problems
|
||||
|
||||
**Projection Issues**:
|
||||
- Content visible on laptop but cut off when projected
|
||||
- Colors looking different on projector
|
||||
- Low contrast elements becoming invisible
|
||||
- Small details disappearing
|
||||
|
||||
### Benefits of Visual Review
|
||||
|
||||
- **Catch layout errors early**: Fix before printing or presenting
|
||||
- **Verify readability**: Ensure text is large enough and high contrast
|
||||
- **Check consistency**: Spot inconsistencies across slides
|
||||
- **Test accessibility**: Verify color contrast and clarity
|
||||
- **Validate design**: Ensure professional appearance
|
||||
|
||||
## Conversion: PDF to Images
|
||||
|
||||
### Method 1: Using pdftoppm (Recommended)
|
||||
|
||||
**Installation**:
|
||||
```bash
|
||||
# Ubuntu/Debian
|
||||
sudo apt-get install poppler-utils
|
||||
|
||||
# macOS
|
||||
brew install poppler
|
||||
|
||||
# Verify installation
|
||||
pdftoppm -v
|
||||
```
|
||||
|
||||
**Basic Conversion**:
|
||||
```bash
|
||||
# Convert all slides to JPEG images
|
||||
pdftoppm -jpeg -r 150 presentation.pdf slide
|
||||
|
||||
# Creates: slide-1.jpg, slide-2.jpg, slide-3.jpg, ...
|
||||
```
|
||||
|
||||
**High-Resolution Conversion**:
|
||||
```bash
|
||||
# Higher quality for detailed inspection (300 DPI)
|
||||
pdftoppm -jpeg -r 300 presentation.pdf slide
|
||||
|
||||
# PNG format (lossless, larger files)
|
||||
pdftoppm -png -r 150 presentation.pdf slide
|
||||
```
|
||||
|
||||
**Convert Specific Slides**:
|
||||
```bash
|
||||
# Slides 5-10 only
|
||||
pdftoppm -jpeg -r 150 -f 5 -l 10 presentation.pdf slide
|
||||
|
||||
# Single slide
|
||||
pdftoppm -jpeg -r 150 -f 3 -l 3 presentation.pdf slide
|
||||
```
|
||||
|
||||
**Output Options**:
|
||||
```bash
|
||||
# Different output directory
|
||||
pdftoppm -jpeg -r 150 presentation.pdf review/slide
|
||||
|
||||
# Custom naming
|
||||
pdftoppm -jpeg -r 150 presentation.pdf output/presentation
|
||||
```
|
||||
|
||||
### Method 2: Using PowerPoint Thumbnail Script
|
||||
|
||||
For PowerPoint presentations, use the pptx skill's thumbnail tool:
|
||||
|
||||
```bash
|
||||
# Create thumbnail grid
|
||||
python scripts/thumbnail.py presentation.pptx output --cols 4
|
||||
|
||||
# Individual slides
|
||||
python scripts/thumbnail.py presentation.pptx slides/slide --individual
|
||||
```
|
||||
|
||||
**Advantages**:
|
||||
- Optimized for PowerPoint files
|
||||
- Can create overview grids
|
||||
- Handles .pptx format directly
|
||||
- Customizable layout
|
||||
|
||||
### Method 3: Using ImageMagick
|
||||
|
||||
**Installation**:
|
||||
```bash
|
||||
# Ubuntu/Debian
|
||||
sudo apt-get install imagemagick
|
||||
|
||||
# macOS
|
||||
brew install imagemagick
|
||||
```
|
||||
|
||||
**Conversion**:
|
||||
```bash
|
||||
# Convert PDF to images
|
||||
convert -density 150 presentation.pdf slide.jpg
|
||||
|
||||
# Higher quality
|
||||
convert -density 300 presentation.pdf slide.jpg
|
||||
|
||||
# Specific format
|
||||
convert -density 150 presentation.pdf slide.png
|
||||
```
|
||||
|
||||
### Method 4: Using Python (Programmatic)
|
||||
|
||||
```python
|
||||
from pdf2image import convert_from_path
|
||||
|
||||
# Convert PDF to images
|
||||
images = convert_from_path(
|
||||
'presentation.pdf',
|
||||
dpi=200,
|
||||
fmt='jpeg'
|
||||
)
|
||||
|
||||
# Save individual slides
|
||||
for i, image in enumerate(images, start=1):
|
||||
image.save(f'slide-{i:03d}.jpg', 'JPEG')
|
||||
```
|
||||
|
||||
**Install pdf2image**:
|
||||
```bash
|
||||
pip install pdf2image
|
||||
# Also requires poppler
|
||||
```
|
||||
|
||||
## Systematic Visual Inspection
|
||||
|
||||
### Inspection Workflow
|
||||
|
||||
**Step 1: Overview Pass**
|
||||
- View all slides quickly
|
||||
- Note overall consistency
|
||||
- Identify obviously problematic slides
|
||||
- Create list of slides needing detailed review
|
||||
|
||||
**Step 2: Detailed Inspection**
|
||||
- Review each flagged slide carefully
|
||||
- Check against issue checklist (below)
|
||||
- Document specific problems with slide numbers

- Check consistency across similar slides
|
||||
- Verify uniform spacing and alignment
|
||||
- Ensure consistent font sizes
|
||||
- Check color scheme consistency
|
||||
|
||||
**Step 4: Distance Test**
|
||||
- View images at reduced size (simulates projection)
|
||||
- Check readability from ~6 feet
|
||||
- Verify key elements are visible
|
||||
- Test if main message is clear

## Common Issues and Solutions
|
||||
|
||||
### Issue 1: Text Overflow
|
||||
|
||||
**Problem**: Text extends beyond boundaries
|
||||
|
||||
**Identification**:
|
||||
- Visible text cut off at edge
|
||||
- Text running into margins
|
||||
- Partial characters visible
|
||||
|
||||
**Solutions**:
|
||||
|
||||
**LaTeX Beamer**:
|
||||
```latex
|
||||
% Reduce text
|
||||
\begin{frame}{Title}
|
||||
\begin{itemize}
|
||||
\item Shorten this long bullet point
|
||||
% or
|
||||
\item Use abbreviations or acronyms
|
||||
% or
|
||||
\item<alert@1> Split into multiple bullets
|
||||
\end{itemize}
|
||||
\end{frame}
|
||||
|
||||
% Adjust margins
|
||||
\newgeometry{margin=1.5cm}
|
||||
\begin{frame}
|
||||
Content with wider margins
|
||||
\end{frame}
|
||||
\restoregeometry
|
||||
|
||||
% Smaller font for specific element
|
||||
{\small
|
||||
Long text that needs to fit
|
||||
}
|
||||
```
|
||||
|
||||
**PowerPoint**:
|
||||
- Reduce font size for that element
|
||||
- Shorten text content
|
||||
- Increase text box size
|
||||
- Use text box auto-fit options (cautiously)
|
||||
- Split into multiple slides
|
||||
|
||||
### Issue 2: Element Overlap
|
||||
|
||||
**Problem**: Elements overlapping inappropriately
|
||||
|
||||
**Identification**:
|
||||
- Text obscured by images
|
||||
- Shapes covering text
|
||||
- Figures overlapping
|
||||
|
||||
**Solutions**:
|
||||
|
||||
**LaTeX Beamer**:
|
||||
```latex
|
||||
% Use columns for better separation
|
||||
\begin{columns}
|
||||
\begin{column}{0.5\textwidth}
|
||||
Text content
|
||||
\end{column}
|
||||
\begin{column}{0.5\textwidth}
|
||||
\includegraphics[width=\textwidth]{figure.pdf}
|
||||
\end{column}
|
||||
\end{columns}
|
||||
|
||||
% Add spacing
|
||||
\vspace{0.5cm}
|
||||
|
||||
% Adjust figure size
|
||||
\includegraphics[width=0.7\textwidth]{figure.pdf}
|
||||
```
|
||||
|
||||
**PowerPoint**:
|
||||
- Use alignment guides to reposition
|
||||
- Reduce element sizes
|
||||
- Use two-column layout
|
||||
- Send elements backward/forward (layering)
|
||||
- Increase spacing between elements
|
||||
|
||||
### Issue 3: Poor Contrast
|
||||
|
||||
**Problem**: Text difficult to read due to color choices
|
||||
|
||||
**Identification**:
|
||||
- Squinting required to read text
|
||||
- Text fades into background
|
||||
- Colors too similar
|
||||
|
||||
**Solutions**:
|
||||
|
||||
**LaTeX Beamer**:
|
||||
```latex
|
||||
% Increase contrast
|
||||
\setbeamercolor{frametitle}{fg=black,bg=white}
|
||||
\setbeamercolor{normal text}{fg=black,bg=white}
|
||||
|
||||
% Use darker colors
|
||||
\definecolor{darkblue}{RGB}{0,50,100}
|
||||
\setbeamercolor{structure}{fg=darkblue}
|
||||
|
||||
% Test in grayscale
|
||||
\usepackage{xcolor}
|
||||
\selectcolormodel{gray} % Temporarily for testing
|
||||
```
|
||||
|
||||
**PowerPoint**:
|
||||
- Choose high-contrast color combinations
|
||||
- Use dark text on light background or vice versa
|
||||
- Avoid pastels for text
|
||||
- Test with WebAIM contrast checker
|
||||
- Add text background box if needed
|
||||
|
||||
### Issue 4: Tiny Fonts
|
||||
|
||||
**Problem**: Text too small to read from distance
|
||||
|
||||
**Identification**:
|
||||
- Can't read text from 3 feet away
|
||||
- Axis labels disappear when viewing normally
|
||||
- Captions illegible
|
||||
|
||||
**Solutions**:
|
||||
|
||||
**LaTeX Beamer**:
|
||||
```latex
|
||||
% Increase base font size
|
||||
\documentclass[14pt]{beamer} % Instead of 11pt default
|
||||
|
||||
% Recreate figures with larger fonts
|
||||
% In matplotlib:
|
||||
plt.rcParams['font.size'] = 18
|
||||
plt.rcParams['axes.labelsize'] = 20
|
||||
|
||||
% In R/ggplot2:
|
||||
theme_set(theme_minimal(base_size = 16))
|
||||
```
|
||||
|
||||
**PowerPoint**:
|
||||
- Minimum 18pt for body text, 24pt preferred
|
||||
- Recreate figures with larger labels
|
||||
- Use direct labeling instead of legends
|
||||
- Simplify complex figures
|
||||
- Split dense content across multiple slides
|
||||
|
||||
### Issue 5: Misalignment
|
||||
|
||||
**Problem**: Elements not properly aligned
|
||||
|
||||
**Identification**:
|
||||
- Uneven margins
|
||||
- Titles at different positions
|
||||
- Irregular spacing
|
||||
|
||||
**Solutions**:
|
||||
|
||||
**LaTeX Beamer**:
|
||||
```latex
|
||||
% Use consistent templates
|
||||
\setbeamertemplate{frametitle}[default][center]
|
||||
|
||||
% Align columns at top
|
||||
\begin{columns}[T] % T = top alignment
|
||||
\begin{column}{0.5\textwidth}
|
||||
Content
|
||||
\end{column}
|
||||
\begin{column}{0.5\textwidth}
|
||||
Content
|
||||
\end{column}
|
||||
\end{columns}
|
||||
|
||||
% Center figures
|
||||
\begin{center}
|
||||
\includegraphics[width=0.8\textwidth]{figure.pdf}
|
||||
\end{center}
|
||||
```
|
||||
|
||||
**PowerPoint**:
|
||||
- Use alignment tools (Align Left/Center/Right)
|
||||
- Enable gridlines and guides
|
||||
- Use snap to grid
|
||||
- Distribute objects evenly
|
||||
- Create master slides with consistent layouts
|
||||
|
||||
## Iterative Improvement Process
|
||||
|
||||
### Workflow Cycle
|
||||
|
||||
```
|
||||
1. Generate PDF
|
||||
↓
|
||||
2. Convert to images
|
||||
↓
|
||||
3. Systematic visual inspection
|
||||
↓
|
||||
4. Document issues
|
||||
↓
|
||||
5. Prioritize fixes
|
||||
↓
|
||||
6. Apply corrections to source
|
||||
↓
|
||||
7. Regenerate PDF
|
||||
↓
|
||||
8. Re-inspect (go to step 2)
|
||||
↓
|
||||
9. Complete when no critical issues remain
|
||||
```
|
||||
|
||||
### Prioritization Strategy
|
||||
|
||||
**Fix Immediately** (Block presentation):
|
||||
- Text overflow making content unreadable
|
||||
- Critical element overlaps obscuring data
|
||||
- Broken figures or missing content
|
||||
- Severely poor contrast
|
||||
|
||||
**Fix Before Presenting**:
|
||||
- Font sizes too small
|
||||
- Moderate alignment issues
|
||||
- Inconsistent spacing
|
||||
- Moderate contrast problems
|
||||
|
||||
**Fix If Time Permits**:
|
||||
- Minor misalignments
|
||||
- Small spacing inconsistencies
|
||||
- Cosmetic improvements
|
||||
- Non-critical color adjustments
|
||||
|
||||
### Stopping Criteria

||||
|
||||
**Minimum Standards**:
|
||||
- [ ] No text overflow or truncation
|
||||
- [ ] No element overlaps obscuring content
|
||||

|
||||
- [ ] Adequate contrast (4.5:1 ratio minimum)
|
||||
- [ ] Figures and images display correctly
|
||||

|
||||
|
||||
## Automated Detection Strategies
|
||||
|
||||
### Python Script for Text Overflow Detection
|
||||
|
||||
```python
|
||||
from PIL import Image
|
||||
import numpy as np
|
||||
|
||||
def detect_edge_content(image_path, threshold=10):
|
||||
"""
|
||||
Detect if content extends too close to slide edges.
|
||||
Returns True if potential overflow detected.
|
||||
"""
|
||||
img = Image.open(image_path).convert('L') # Grayscale
|
||||
arr = np.array(img)
|
||||
|
||||
# Check edges (10 pixel border)
|
||||
left_edge = arr[:, :threshold]
|
||||
right_edge = arr[:, -threshold:]
|
||||
top_edge = arr[:threshold, :]
|
||||
bottom_edge = arr[-threshold:, :]
|
||||
|
||||
# Look for non-white pixels (content)
|
||||
white_threshold = 240
|
||||
|
||||
issues = []
|
||||
if np.any(left_edge < white_threshold):
|
||||
issues.append("Left edge")
|
||||
if np.any(right_edge < white_threshold):
|
||||
issues.append("Right edge")
|
||||
if np.any(top_edge < white_threshold):
|
||||
issues.append("Top edge")
|
||||
if np.any(bottom_edge < white_threshold):
|
||||
issues.append("Bottom edge")
|
||||
|
||||
return issues
|
||||
|
||||
# Usage
|
||||
for slide_num in range(1, 26):
|
||||
issues = detect_edge_content(f'slide-{slide_num}.jpg')
|
||||
if issues:
|
||||
print(f"Slide {slide_num}: Content near {', '.join(issues)}")
|
||||
```
|
||||
|
||||
### Contrast Checking
|
||||
|
||||
```python
|
||||
from PIL import Image
|
||||
import numpy as np
|
||||
|
||||
def check_contrast(image_path):
|
||||
"""
|
||||
Estimate contrast ratio in image.
|
||||
Simple version: compare lightest and darkest regions.
|
||||
"""
|
||||
img = Image.open(image_path).convert('L')
|
||||
arr = np.array(img)
|
||||
|
||||
# Get brightness values
|
||||
bright = np.percentile(arr, 95)
|
||||
dark = np.percentile(arr, 5)
|
||||
|
||||
# Rough contrast ratio
|
||||
contrast = (bright + 0.05) / (dark + 0.05)
|
||||
|
||||
if contrast < 4.5:
|
||||
return f"Low contrast: {contrast:.1f}:1 (minimum 4.5:1)"
|
||||
return f"OK: {contrast:.1f}:1"
|
||||
|
||||
# Usage
|
||||
for slide_num in range(1, 26):
|
||||
result = check_contrast(f'slide-{slide_num}.jpg')
|
||||
print(f"Slide {slide_num}: {result}")
|
||||
```
|
||||
|
||||
## Manual Review Best Practices
|
||||
|
||||
### Review Environment
|
||||
|
||||
**Setup**:
|
||||
- Large monitor or dual monitors
|
||||
- Good lighting (not too bright, not dark)
|
||||
- Distraction-free environment
|
||||
- Image viewer with zoom capability
|
||||
- Notepad or spreadsheet for tracking issues
|
||||
|
||||
**Viewing Options**:
|
||||
- View at 100% for detail inspection
|
||||
- View at 50% to simulate distance
|
||||
- View in sequence to check consistency
|
||||
- Compare similar slides side-by-side
|
||||
|
||||
### Review Tips
|
||||
|
||||
**Fresh Eyes**:
|
||||
- Take breaks every 15-20 slides
|
||||
- Review at different times of day
|
||||
- Get colleague to review
|
||||
- Come back next day for final check
|
||||
|
||||
**Systematic Approach**:
|
||||
- Review in order (slide 1 → end)
|
||||
- Focus on one issue type at a time
|
||||
- Use checklist to ensure thoroughness
|
||||
- Document as you go, not from memory
|
||||
|
||||
**Common Oversights**:
|
||||
- Backup slides (review these too!)
|
||||
- Title slide (first impression matters)
|
||||
- Acknowledgments slide (often forgotten)
|
||||
- Last slide (visible during Q&A)
|
||||
|
||||
