Configuration

Edit config.py to customize:

Detection Sensitivity

MIN_DETECTION_CONFIDENCE = 0.1  # Lower = more sensitive (0.1-0.9)
MIN_TRACKING_CONFIDENCE = 0.1   # Lower = smoother tracking

Mouse Settings

MOUSE_SPEED = 1.8          # Cursor speed multiplier
MOUSE_SMOOTHING = 3        # Smoothing buffer size
SCROLL_SPEED = 25          # Scroll sensitivity

Keyboard Settings

KEY_SIZE = 80              # Key size in pixels
KEY_PADDING = 20           # Space between keys
DWELL_TIME = 0.8           # Hover time to type (seconds)

Visual Settings

PRIMARY_COLOR = (255, 140, 0)      # Orange - Main accent
SUCCESS_COLOR = (0, 255, 0)        # Green - Success/Active
SHOW_FPS = True                    # Display FPS counter
SHOW_LANDMARKS = True              # Show hand skeleton

Troubleshooting

Hand not detected?

• Ensure good lighting (system works in poor lighting but better is always better)
• Spread fingers apart when entering frame
• Move hand slowly into center of frame
• Try lowering MIN_DETECTION_CONFIDENCE to 0.05 in config.py

Camera not working?

• Check if camera is being used by another application
• Try different camera index in config.py: CAMERA_INDEX = 0 (or 1, 2)
• Verify camera permissions in system settings

Performance issues?

• Close other applications using the camera
• Disable image enhancement: ENABLE_IMAGE_ENHANCEMENT = False in config.py
• Reduce frame size: FRAME_WIDTH = 640, FRAME_HEIGHT = 480 in config.py

Gestures not working?

• Ensure hand is clearly visible in frame
• Check that fingers are spread apart
• Adjust CLICK_THRESHOLD in config.py (higher = easier to trigger)
