PPTX Research Posters (HTML-Based)

Overview

⚠️ USE THIS SKILL ONLY WHEN USER EXPLICITLY REQUESTS PPTX/POWERPOINT POSTER FORMAT.

For standard research posters, use the latex-posters skill instead, which provides better typographic control and is the default for academic conferences.

This skill creates research posters using HTML/CSS, which can then be exported to PDF or converted to PowerPoint format. The web-based approach offers:

• Modern, responsive layouts
• Easy integration of AI-generated visuals
• Quick iteration and preview in browser
• Export to PDF via browser print function
• Conversion to PPTX if specifically needed

When to Use This Skill

ONLY use this skill when:

• User explicitly requests "PPTX poster", "PowerPoint poster", or "PPT poster"
• User specifically asks for HTML-based poster
• User needs to edit poster in PowerPoint after creation
• LaTeX is not available or user requests non-LaTeX solution

DO NOT use this skill when:

• User asks for a "poster" without specifying format → Use latex-posters
• User asks for "research poster" or "conference poster" → Use latex-posters
• User mentions LaTeX, tikzposter, beamerposter, or baposter → Use latex-posters

AI-Powered Visual Element Generation

STANDARD WORKFLOW: Generate ALL major visual elements using AI before creating the HTML poster.

This is the recommended approach for creating visually compelling posters:

1. Plan all visual elements needed (hero image, intro, methods, results, conclusions)
2. Generate each element using scientific-schematics or Nano Banana Pro
3. Assemble generated images in the HTML template
4. Add text content around the visuals

Target: 60-70% of poster area should be AI-generated visuals, 30-40% text.

CRITICAL: Poster-Size Font Requirements

⚠️ ALL text within AI-generated visualizations MUST be poster-readable.

When generating graphics for posters, you MUST include font size specifications in EVERY prompt. Poster graphics are viewed from 4-6 feet away, so text must be LARGE.

MANDATORY prompt requirements for EVERY poster graphic:

POSTER FORMAT REQUIREMENTS (STRICTLY ENFORCE):
- ABSOLUTE MAXIMUM 3-4 elements per graphic (3 is ideal)
- ABSOLUTE MAXIMUM 10 words total in the entire graphic
- NO complex workflows with 5+ steps (split into 2-3 simple graphics instead)
- NO multi-level nested diagrams (flatten to single level)
- NO case studies with multiple sub-sections (one key point per case)
- ALL text GIANT BOLD (80pt+ for labels, 120pt+ for key numbers)
- High contrast ONLY (dark on white OR white on dark, NO gradients with text)
- MANDATORY 50% white space minimum (half the graphic should be empty)
- Thick lines only (5px+ minimum), large icons (200px+ minimum)
- ONE SINGLE MESSAGE per graphic (not 3 related messages)

⚠️ BEFORE GENERATING: Review your prompt and count elements

• If your description has 5+ items → STOP. Split into multiple graphics
• If your workflow has 5+ stages → STOP. Show only 3-4 high-level steps
• If your comparison has 4+ methods → STOP. Show only top 3 or Our vs Best Baseline

Example - WRONG (7-stage workflow):

# ❌ Creates tiny unreadable text
python scripts/generate_schematic.py "Drug discovery workflow: Stage 1 Target ID, Stage 2 Synthesis, Stage 3 Screening, Stage 4 Lead Opt, Stage 5 Validation, Stage 6 Clinical Trial, Stage 7 FDA Approval with metrics." -o figures/workflow.png

Example - CORRECT (3 mega-stages):

# ✅ Same content, simplified to readable poster format
python scripts/generate_schematic.py "POSTER FORMAT for A0. ULTRA-SIMPLE 3-box workflow: 'DISCOVER' → 'VALIDATE' → 'APPROVE'. Each word in GIANT bold (120pt+). Thick arrows (10px). 60% white space. ONLY these 3 words. NO substeps. Readable from 12 feet." -o figures/workflow_simple.png

CRITICAL: Preventing Content Overflow

⚠️ POSTERS MUST NOT HAVE TEXT OR CONTENT CUT OFF AT EDGES.

Prevention Rules:

1. Limit Content Sections (MAXIMUM 5-6 sections):

✅ GOOD - 5 sections with room to breathe:
   - Title/Header
   - Introduction/Problem
   - Methods
   - Results (1-2 key findings)
   - Conclusions

❌ BAD - 8+ sections crammed together

2. Word Count Limits:

• Per section: 50-100 words maximum
• Total poster: 300-800 words MAXIMUM
• If you have more content: Cut it or make a handout

Core Capabilities

1. HTML/CSS Poster Design

The HTML template (assets/poster_html_template.html) provides:

• Fixed poster dimensions (36×48 inches = 2592×3456 pt)
• Professional header with gradient styling
• Three-column content layout
• Block-based sections with modern styling
• Footer with references and contact info

2. Poster Structure

Standard Layout:

┌─────────────────────────────────────────┐
│  HEADER: Title, Authors, Hero Image     │
├─────────────┬─────────────┬─────────────┤
│ Introduction│   Results   │  Discussion │
│             │             │             │
│   Methods   │   (charts)  │ Conclusions │
│             │             │             │
│  (diagram)  │   (data)    │   (summary) │
├─────────────┴─────────────┴─────────────┤
│  FOOTER: References & Contact Info      │
└─────────────────────────────────────────┘

3. Visual Integration

Each section should prominently feature AI-generated visuals:

Hero Image (Header):

<img src="figures/hero.png" class="hero-image">

Section Graphics:

<div class="block">
  <h2 class="block-title">Methods</h2>
  <div class="block-content">
    <img src="figures/workflow.png" class="block-image">
    <ul>
      <li>Brief methodology point</li>
    </ul>
  </div>
</div>

4. Generating Visual Elements

Before creating the HTML, generate all visual elements:

# Create figures directory
mkdir -p figures

# Hero image - SIMPLE, impactful
python scripts/generate_schematic.py "POSTER FORMAT for A0. Hero banner: '[TOPIC]' in HUGE text (120pt+). Dark blue gradient background. ONE iconic visual. Minimal text. Readable from 15 feet." -o figures/hero.png

# Introduction visual - ONLY 3 elements
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE visual with ONLY 3 icons: [icon1] → [icon2] → [icon3]. ONE word labels (80pt+). 50% white space. Readable from 8 feet." -o figures/intro.png

# Methods flowchart - ONLY 4 steps
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE flowchart with ONLY 4 boxes: STEP1 → STEP2 → STEP3 → STEP4. GIANT labels (100pt+). Thick arrows. 50% white space. NO sub-steps." -o figures/workflow.png

# Results visualization - ONLY 3 bars
python scripts/generate_schematic.py "POSTER FORMAT for A0. SIMPLE bar chart with ONLY 3 bars: BASELINE (70%), EXISTING (85%), OURS (95%). GIANT percentages ON bars (120pt+). NO axis, NO legend. 50% white space." -o figures/results.png

# Conclusions - EXACTLY 3 key findings
python scripts/generate_schematic.py "POSTER FORMAT for A0. EXACTLY 3 cards: '95%' (150pt) 'ACCURACY' (60pt), '2X' (150pt) 'FASTER' (60pt), checkmark 'READY' (60pt). 50% white space. NO other text." -o figures/conclusions.png

Workflow for PPTX Poster Creation

Stage 1: Planning

1. Confirm PPTX is explicitly requested
2. Determine poster requirements:
   • Size: 36×48 inches (most common) or A0
   • Orientation: Portrait (most common)
3. Develop content outline:
   • Identify 1-3 core messages
   • Plan 3-5 visual elements
   • Draft minimal text (300-800 words total)

Stage 2: Generate Visual Elements (AI-Powered)

CRITICAL: Generate SIMPLE figures with MINIMAL content.

mkdir -p figures

# Generate each element with POSTER FORMAT specifications
# (See examples in Section 4 above)

Stage 3: Create HTML Poster

1. Copy the template:

   cp skills/pptx-posters/assets/poster_html_template.html poster.html
   

2. Update content:

   • Replace placeholder title and authors
   • Insert AI-genera
