- see hable one. A few FOSS variants have been tried but failed - look up “switch boxes” - look up “eyegaze” hardware

Truth is hardware is actually hard to get absolutely right. Software - now there’s tons of space on this. The problem is identifying the big pinch points. If anyone there wants to help us look at these priorities

- ows. An open wireless switch box https://github.com/AceCentre/OWS/tree/main (largely hardware) - echo. SwiftUI app. Aiming to provide speech to blind and physically impaired and with no voice. https://github.com/AceCentre/Echo - facecommander. A fork of googles gameface that was appallingly bug ridden. Use your face gestures to act as keyboard inputs https://github.com/AceCentre/FaceCommander - dasher. This needs a lot of c++ https://github.com/dasher-project/dasher-MIT/ its the fastest text entry system for head mouse , eyegaze users etc but woefully old
