HandTracker

HandTracker is a webcam hand-tracking tool that turns finger curls into keyboard inputs.

It uses OpenCV and MediaPipe to detect one hand in real time. When you curl a finger, the app presses a matching keyboard key. When you open the finger again, the key is released.

The thumb detection also checks for a closed fist, so the thumb should count as pressed when it is tucked across the palm.

   • Type left, right, or both.
   • Press Enter to use the default: both.
5. Curl your fingers to press the matching keys.
6. Press Q in the camera window to quit.
