Virtual Mouse & Gesture-Based Volume Control Project

Описание: What if you could control your computer without touching it?

I built a gesture-controlled system that turns your hands into a virtual mouse and volume controller, using only a webcam, MediaPipe, and some computer vision logic.

In the demo video, you’ll see:
1) Right hand → Virtual mouse
Index finger moves the cursor by mapping fingertip coordinates to native screen resolution
Index + middle finger pinch triggers a mouse click, detected by measuring the distance between landmarks
Motion is smoothed with interpolation so the cursor feels stable, not jittery

2) Left hand → Volume control
The distance between thumb and index finger maps (via np.interp) to the Windows master volume using pycaw
Closing fingers lowers volume, spreading them raises it, with a live volume bar overlay for feedback

For me, this project was about more than just moving a cursor. It was about exploring touchless, intuitive interfaces that could be useful in accessibility tools, presentation control, sterile environments, and public kiosks.

I would love to connect.
