+# World-Class UI & Alert Management Improvements
+
+## Problems Fixed
+
+### 1. Alert State Management ✅
+**Problem**: Alerts stayed ACTIVE forever once triggered, even when conditions cleared.
+
+**Solution**: Implemented temporal smoothing with alert persistence tracking:
+- Alerts clear automatically when conditions stop
+- Configurable persistence frames for each alert type
+- Smooth transitions between states
+
+### 2. UI Improvements for Chromium/Raspberry Pi ✅
+**Problem**: 
+- Emojis not visible in Chromium
+- Poor visual feedback
+- Unprofessional appearance
+
+**Solution**: 
+- Removed emojis, replaced with CSS-based indicators
+- Professional color-coded alert system
+- Modern card-based layout
+- Better visual hierarchy
+
+## Technical Implementation
+
+### Alert Persistence System
+
+```python
+# Track how long alerts have been inactive
+self.alert_persistence = {
+    'Drowsiness': 0,
+    'Distraction': 0,
+    'Driver Absent': 0,
+    'Phone Detected': 0,
+    'No Seatbelt': 0,
+}
+
+# Frames to wait before clearing (temporal smoothing)
+self.alert_clear_frames = {
+    'Drowsiness': 10,  # ~0.3s at 30fps
+    'Distraction': 8,
+    'Driver Absent': 5,  # Immediate
+    'Phone Detected': 5,
+    'No Seatbelt': 8,
+}
+```
+
+### Alert Clearing Logic
+
+```python
+if triggered:
+    # Set alert active, reset counter
+    self.alert_states[alert] = True
+    self.alert_persistence[alert] = 0
+else:
+    # Increment counter, clear if threshold reached
+    self.alert_persistence[alert] += 1
+    if self.alert_persistence[alert] >= threshold:
+        self.alert_states[alert] = False
+```
+
+## UI Enhancements
+
+### CSS Styling
+- **Alert Active**: Red border, light red background
+- **Alert Normal**: Green border, light green background
+- **Status Badges**: Color-coded pills (ACTIVE/Normal)
+- **Modern Cards**: Clean, professional appearance
+- **Better Typography**: Improved readability
+
+### Visual Indicators
+- **ACTIVE**: Red badge with white text
+- **Normal**: Green badge with white text
+- **No Emojis**: Pure CSS/HTML for Chromium compatibility
+
+### Performance Optimizations
+- Optimized YOLO inference (contiguous arrays)
+- Faster image resizing (INTER_LINEAR)
+- Log management (limit to 10 entries)
+- Efficient frame processing
+
+## Benefits
+
+### User Experience
+✅ **Real-time feedback** - Alerts clear when conditions stop
+✅ **Professional appearance** - Modern, clean UI
+✅ **Better visibility** - Color-coded status indicators
+✅ **Smooth transitions** - No jarring state changes
+
+### Performance
+✅ **Faster inference** - Optimized YOLO processing
+✅ **Lower memory** - Limited log entries
+✅ **Better FPS** - Improved frame processing
+
+### Reliability
+✅ **Accurate alerts** - Temporal smoothing prevents false positives
+✅ **Consistent behavior** - Alerts clear predictably
+✅ **Cross-platform** - Works on Chromium/Raspberry Pi
+
+## Example Behavior
+
+### Phone Detection
+1. Phone appears → Alert becomes ACTIVE (red)
+2. Phone removed → Counter starts
+3. After 5 frames (~0.17s) → Alert clears to Normal (green)
+
+### Drowsiness Detection
+1. Eyes close → Alert becomes ACTIVE
+2. Eyes open → Counter starts
+3. After 10 frames (~0.3s) → Alert clears to Normal
+
+This prevents flickering while ensuring alerts clear when conditions stop!
