GesturePlay

Control YouTube / Bilibili with webcam hand gestures: pinch to drag the progress bar, make a fist to play/pause.

Control video playback without touching your mouse or keyboard — just your hand and your webcam. GESTURES • Pinch (thumb + index, with your other three fingers raised) and move your hand left/right to scrub the video timeline — the site's own progress bar follows live. • Hold a fist (~half a second) to toggle play / pause. • Open your palm or drop your hand to do nothing — it's the resting pose. WORKS GREAT • On youtube.com and bilibili.com video pages. • While playing, while paused, and in fullscreen. • Fine scrubbing by default: one full hand sweep = 1 minute (configurable: 30 s to 5 min, or the whole video). TUNABLE Click the toolbar icon for live-updating settings: master on/off switch, scrub range, start deadzone, fist hold time, fingers required, pinch sensitivity, English/中文 interface, and an optional camera preview with a hand-skeleton overlay for tuning. PRIVATE BY DESIGN All hand tracking runs locally in your browser using Google's MediaPipe model, which is bundled inside the extension. No video frame ever leaves your machine. The extension makes zero network requests: no analytics, no accounts, no servers.
