Recognize Hand
Gestures Instantly
The most advanced browser-based gesture recognition system. No downloads, no servers — pure on-device AI intelligence running at 30+ FPS.
How It Works
A 4-stage AI pipeline running entirely on your device
Capture
WebRTC streams your webcam at 30 fps via the secure MediaDevices API
Detect
MediaPipe neural network locates your hand and extracts 21 3D landmarks
Analyze
Heuristic math computes finger angles, distances and joint ratios
Classify
Gesture is classified and UI updates with color, sound, and feedback
Edge Computing
AI inference runs locally inside the browser via WebAssembly. Zero server latency.
MediaPipe Tracking
Tracks 21 hand joints in real-time using lightweight, edge-optimized neural networks.
Spatial Math
Runs geometric equations on-device to compute joint angles and distance vectors instantly.
SYSTEM READY
