Hand Gesture-Based Brightness Control

This Python project uses computer vision techniques to control screen brightness dynamically through hand gestures. The system leverages OpenCV for video capture and hand tracking, while screen_brightness_control is used to modify the brightness settings.

Setup Instructions

1. Install Dependencies:

   pip install opencv-python numpy screen-brightness-control

2. Verify the Custom Module:

   • Place handlTrackingModule.py in the same directory as the script.
   • Ensure it provides the handDetector class with the following methods:
     • findHands(img)
     • findPosition(img, draw)

3. Run the Script:

   python script_name.py

Usage

1. Start the script and position your hand in front of the camera.
2. Adjust the distance between your thumb and index finger to control brightness:
   • Closer fingers = Lower brightness
   • Further apart = Higher brightness
3. Press q to quit the application.

Troubleshooting

1. Camera Not Detected:

   • Ensure your webcam is functional and accessible.
   • Check camera permissions on your system.

2. Hand Not Detected:

   • Ensure adequate lighting.
   • Position your hand within the camera's frame.

3. Brightness Not Changing:

   • Verify screen_brightness_control is installed and supports your system.
   • Check for any errors in the handlTrackingModule implementation.

Happy Coding! 🎉
