Grasp

Hand-gesture physics sandbox in one self-contained HTML file (index.html). Your webcam is the controller: pinch to grab, release to throw, point to poke. Mouse/touch fallback when the camera or tracker is unavailable.

• Physics: Matter.js 0.20.0 (cdnjs)
• Hand tracking: MediaPipe Tasks Vision HandLandmarker 0.10.35 (jsDelivr), VIDEO mode, 1 hand
• All tuning constants live in CONFIG at the top of the script
• Press D (or the HUD button) for live diagnostics

Hosting

Camera mode does not work inside claude.ai artifacts (the iframe blocks the camera and the CSP blocks the model/WASM). It is deployed as a static site on Vercel, project grasp.

Also in this repo

• Slice mode in Grasp: swipe a raised index finger through flying fruit.
• Tremor meter at /tremor/ (tremorti/index.html).

Tests

Headless Playwright tests (stubbed tracker, fake camera): bash tests/run.sh and bash tremorti/tests/run.sh.
