AshySpeak
Commercial eye-gaze systems cost thousands and nearly all require the user to follow a sequence of dots before they work. Many disabled children physically cannot do that — which excludes exactly the people who need gaze control most.
AshySpeak removes the requirement entirely. Horizontal gaze comes from a projective ratio between the corners of the eye, which barely changes when the head moves. Vertical gaze comes from the upper eyelid rather than the pupil — a discovery from this project's own measurements, where the eyelid tracked vertical gaze roughly three and a half times more reliably at webcam resolution. The system learns each person's neutral and range while they simply use it, so it works on any face, with no targets and nothing stored.
It runs entirely on the local machine on an ordinary webcam, down to budget laptops, and is released free for families, schools, charities and clinicians.
