Contactless Hand Gesture Controller

Touchless interaction enables sterile computing environments, accessibility accommodations, and intuitive natural user interfaces. This project builds a low-latency gesture recognition pipeline running directly on standard consumer webcams.

Using Google's MediaPipe Hands, 21 3D hand landmarks are extracted per frame and fed into a gesture classifier. Coordinate smoothing algorithms eliminate jitter, translating finger distances and spatial geometry into precise mouse cursor movements, click triggers, multi-directional scrolling, and system volume/brightness scaling.
