Head-mouse: A simple cursor controller based on optical measurement of head tilt

The project is a specialized hardware-software reference implementation for assistive technology. With 0 stars and 4 forks over nearly 6 years, it has failed to gain any developer traction or community momentum. From a competitive standpoint, this approach is largely obsolete. Modern computer vision frameworks (like Google's MediaPipe) allow for high-fidelity head and eye tracking using standard webcams, removing the friction of wearing a specialized hardware device. Furthermore, major operating systems (macOS/iOS via 'Head Pointer' and Windows via 'Eye Control') have integrated these capabilities directly into their accessibility layers. The project faces high platform domination risk as Apple and Microsoft treat these features as standard OS-level utilities. Projects like OpenTrack or Cephable provide more robust, software-defined alternatives that leverage existing hardware (webcams, IR trackers). There is no technical moat here; the use of BLE HID is standard, and the optical measurement of tilt is a basic application of sensor fusion.
