Interface Overview
The LEWS interface is designed to be intuitive and accessible while presenting complex risk assessment data. The design follows the principle of making complex systems understandable to non-experts while preserving the detailed information needed by subject matter experts.
Core UI Elements
The main interface consists of seven slider controls, each representing one of the key variables:
1. Uncertainty
❓ Low [════●══════════════════] High
±30 points
2. # Animals
🔢 Low [══════●═══════════════] High
440B/yr • ↑ 8%/yr
3. Can They Feel?
🧠 0% [══════●════════════════] 100%
60% • Medium evidence
4. Suffering
💔 Low [══════●═══════════════] High
4,701 hours lifetime pain
5. Growth
📈 Slow [══════●═══════════════] Fast
$400M • multi-country
6. Support
🧩 Strong [●════════════════════] Weak
Near-zero advocacy
7. Path Dependence
🔗 Low [══════●═══════════════] High
System becoming entrenched
Results Display
The results are displayed in a clear, actionable format:
🔥 Lock-in Risk Score
72 / 100
⏰ Time Until Lock-in
~5–8 years
🚨 Intervention Window
ACT SOON
Range: 58 – 86
Key Metrics
- • 264B animals/year
- • 1.24T hours suffering
- • 0 orgs today
- • Lock-in ~5–8 years
Technology Selection
The interface allows users to select between different animal farming technologies:
Historical Trajectory View
When users click "View Trajectory", a modal appears showing historical data:
Historical Trajectory Comparison
Lock-in Score
100 ┤ ● CURRENT
80 ┤ ●●●
60 ┤ ●●● ← Chicken 1950
40 ┤ ●●●
20 ┤ ●●●
0 └──────────────────────────────────────────────────────────
1920 1930 1940 1950 1960 1970
Analysis:
• Current shrimp ≈ chicken farming in 1950.
• Expected lock-in at current momentum: 2029–2032.
Design Philosophy
The UI/UX design follows several key principles:
- Clarity: Complex data presented in an accessible format
- Immediate Actionability: Clear intervention window recommendations
- Transparency: All variables and their impact visible
- Visual Hierarchy: Most critical information prominently displayed
- Responsive Design: Works well on different device sizes
Accessibility Considerations
The interface includes features to support accessibility:
- High contrast color schemes
- Clear typography with appropriate sizing
- Keyboard navigation support
- Aria labels for screen readers
- Color-blind friendly visualizations
Visual Design Elements
The interface uses several visual elements to enhance understanding:
- Progress Bars: To visualize ranges and percentages
- Icons: To quickly convey information types
- Color Coding: Red for high risk, green for low risk
- Visual Hierarchy: Typography and spacing to guide attention
- Charts: For historical trajectory visualization
User Flow
The user flow is designed to be simple and intuitive:
- User selects a farming technology (chicken, shrimp, insect farming)
- Default values load based on historical data for that technology
- User adjusts sliders to reflect current conditions
- Real-time risk score updates as sliders are adjusted
- Results are displayed with intervention recommendations
- User can view historical trajectory for context
