🎮 Frontend Integration

Your Existing Frontend

The provided index.html already integrates with the backend:

// WebSocket connection
const ws = new WebSocket('ws://localhost:8000/ws');

ws.onopen = () => {
  console.log('Connected to NETRAX');
};

ws.onmessage = (event) => {
  const data = JSON.parse(event.data);
  
  if (data.type === 'stats') {
    // Update FPS, confidence, etc.
  }
  
  if (data.type === 'gesture_command') {
    // Handle gesture: data.command
  }
};

// Video feed
<img src="http://localhost:8000/video_feed">

Custom Integration

// Connect
const vision = new WebSocket('ws://localhost:8000/ws');

// Handle tracking data
vision.onmessage = (event) => {
  const { type, data } = JSON.parse(event.data);
  
  switch(type) {
    case 'stats':
      updateMetrics(data.stats);
      break;
    
    case 'gesture_command':
      handleGesture(data.command);
      break;
    
    case 'tracking_detail':
      // Full tracking data
      const { body, eyes, gaze } = data.data;
      renderTracking(body, eyes, gaze);
      break;
  }
};

// Send commands
vision.send(JSON.stringify({
  type: 'command',
  command: 'calibrate'
}));

👋 Supported Gestures

Gesture Customization

Edit vision_engine/gesture_engine.py:

def _detect_custom_gesture(self, body_data: Dict) -> float:
    """Detect your custom gesture"""
    # Add your detection logic
    confidence = 0.0
    
    # Return confidence (0.0 to 1.0)
    return confidence

# Register in __init__
self.gesture_rules["custom"] = self._detect_custom_gesture

Performance Tuning

High FPS (60+ FPS):

TARGET_FPS=60
FRAME_WIDTH=640
FRAME_HEIGHT=480
BODY_MODEL_COMPLEXITY=0
ENABLE_OBJECT_DETECTION=false

High Quality (30 FPS):

TARGET_FPS=30
FRAME_WIDTH=1280
FRAME_HEIGHT=720
BODY_MODEL_COMPLEXITY=2
ENABLE_OBJECT_DETECTION=true

Balanced (default):

TARGET_FPS=30
FRAME_WIDTH=1280
FRAME_HEIGHT=720
BODY_MODEL_COMPLEXITY=1

🐛 Troubleshooting

Camera Not Found

# Check camera permissions
ls -la /dev/video*

# Add user to video group (Linux)
sudo usermod -aG video $USER

# Test camera
python -c "import cv2; print(cv2.VideoCapture(0).isOpened())"

Low FPS

# Reduce resolution
FRAME_WIDTH=640
FRAME_HEIGHT=480

# Disable heavy modules
ENABLE_OBJECT_DETECTION=false

# Enable frame skipping
ENABLE_FRAME_SKIP=true

WebSocket Connection Failed

# Check if server is running
curl http://localhost:8000/status

# Check firewall
sudo ufw allow 8000

# Check Docker networking
docker-compose ps

MediaPipe Errors

# Reinstall
pip uninstall mediapipe opencv-python
pip install mediapipe==0.10.8 opencv-python==4.8.1.78

# Check camera access
python -c "import mediapipe as mp; print('OK')"

🔒 Security Notes

Camera access: Only expose port 8000 on trusted networks
WebSocket: No authentication by default - add auth for production
CORS: Currently allows all origins - restrict in production
Data privacy: Video is processed locally, not stored

Production Recommendations

# main.py - Add authentication
from fastapi.security import HTTPBearer

security = HTTPBearer()

@app.websocket("/ws")
async def websocket_endpoint(
    websocket: WebSocket,
    token: str = Depends(security)
):
    # Verify token
    ...
