# OpenParanormal UI Design Guide

**Theme:** Professional High-Tech Paranormal Interface

A distinct fusion of:
- **Professional tech** (military/scientific precision)
- **High-tech cyberpunk** (neon accents, dark backgrounds)
- **Paranormal mystery** (mystical symbols, glowing effects)

## 🎬 Animations & Effects

### Scanline Effect
- Horizontal line slowly moves down screen
- Adds "CRT monitor" retro-tech feel
- Semi-transparent, doesn't interfere with content

### Hex Grid Background
- Subtle hexagonal pattern (dim grey)
- Gives "high-tech" laboratory feel
- Offset rows for proper tessellation
- Only visible on dark areas

### Pulsing Elements
- Glow effect using sine wave brightness
- Words, borders, indicators pulse
- Speed varies by element:
  - Slow: Ambient (3-5 seconds)
  - Medium: Active scan (1-2 seconds)
  - Fast: Alert/Anomaly (<1 second)

### Button Press Animation
- Button fills with color on touch
- Border thickens momentarily
- Haptic feedback (if available)
- Sound effect (optional beep)

### LED Ring Sync
- Physical LEDs mirror on-screen colors
- Ambient: Cyan slow pulse
- Active: Green rapid pulse
- Alert: Red flash

## 📐 Layout Principles

### Screen Zones (3.5" Touchscreen - 480x320)

```
┌────────────────────────────────┐
│  HEADER (0-60px)               │ ← Title, mode name
├────────────────────────────────┤
│                                │
│  MAIN CONTENT (60-260px)       │ ← Readings, graphs, controls
│                                │
│                                │
├────────────────────────────────┤
│  CONTROLS (260-310px)          │ ← Buttons, back button
├────────────────────────────────┤
│  STATUS BAR (310-320px)        │ ← System info
└────────────────────────────────┘
```

### Touch Targets
- Minimum 40x40 pixels
- 10px spacing between buttons
- Rounded corners (8px radius)
- Clear visual feedback

### Text Sizes
- Title: 3 (24pt)
- Readings: 4 (32pt) - large, easy to read in dark
- Buttons: 2 (16pt)
- Status: 1 (8pt)

---

## 🎯 Design Philosophy

### Professional
- Clean layouts
- Precise alignment
- Technical terminology
- Scientific readouts

### High-Tech
- Dark cyberpunk aesthetic
- Neon accent colors
- Animated scan effects
- CRT-style scanlines
- Hex grid patterns

### Paranormal
- Mystical symbols (eye, radar, waves)
- Pulsing "energy" effects
- Anomaly alerts
- "Resonance" terminology
- LED ring atmosphere

### User Experience
- Large touch targets
- Clear mode indication
- Easy navigation
- Consistent back button
- Real-time feedback
- No buried menus

---

## 🔧 Implementation Notes

### Performance
- Update displays at 20-50Hz (20-50ms delay)
- Don't redraw entire screen every frame
- Only update changed elements
- Use fillRect() to clear specific areas

### Power Saving
- Dim display after 30 seconds idle
- Reduce LED ring brightness when not alerting
- Sleep sensors between reads

### Responsiveness
- Touch debounce: 200ms
- Immediate visual feedback
- Audio confirmation (optional)

---

## 🎨 Alternative Color Schemes

### Night Vision Mode
- Primary: Green (#00FF00)
- Secondary: Dark Green (#003300)
- Accent: Yellow-Green (#ADFF2F)
- For low-light investigations

### Thermal Mode
- Primary: Orange (#FF6600)
- Secondary: Red (#FF0000)
- Accent: Yellow (#FFFF00)
- For thermal camera view

### Stealth Mode
- Primary: Dark Blue (#000033)
- Dim everything
- Red-only indicators (preserves night vision)

---

## 📱 Future Enhancements

### Advanced Graphics
- Particle effects (floating data points)
- 3D waveforms
- AR overlay (if ESP32-CAM added)
- Video recording

### Customization
- User theme selection
- Adjustable brightness
- Custom color palettes
- Icon sets

### Data Visualization
- Export graphs as images
- Session replay
- Heatmaps
- Timeline view
