HELM

Helm watches your webcam and turns body movement into desktop control. It recognises static hand poses via MediaPipe's HandLandmarker, reads deliberate facial gestures (brow raise, mouth open/pucker, wink, cheek puff) with per-user calibration, and drives the mouse cursor from head motion using a velocity model with One-Euro smoothing. Three independent controls — Hand, Face, and Pointer — toggle separately and share one efficient engine loop that releases the camera whenever nothing needs it.
Everything runs locally: the video never leaves the machine, and there's no account, telemetry, or network dependency at runtime. It's built pure-core / adapters / app — the side-effect-free core is unit-tested, adapters wrap the OS and camera, and the app layer hosts the engine loop and tray. Opt-in target gravity gently biases the cursor toward nearby buttons and links (via Windows UI Automation) so it settles onto small targets instead of skating past, and a master pause hotkey is the hard stop that releases the camera. It ships as a single-file Helm.exe — no Python needed to run it.
