Eye-Writer: An Eye-Movement Monitor Control System
Brian Blandford, Gerry Dale · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1983
A simple eye-position monitor is described, which has an application as an aid to communication by those without the muscular control necessary to operate a keyboard or microswitch. The output from this device is insensitive to head movements, and it controls the operation of a Sinclair ZX81 microcomputer with a speech synthesizer, Alternatively, if the output is directed to a modified voltmeter, it provides a low-cost portable unit for simple communication tasks.
