The Eye gaze System is a communication system for people with complex physical disabilities.
This operates with eyes by looking at control keys displayed on a screen.
With this system a person can synthesize speech, control his environment , operate a telephone, run computer software, operate a computer mouse, and access the Internet and e-mail.
Edmund Huey built an early eye tracker, using a sort of contact lens with a hole for the pupil. The lens was connected to an aluminum pointer that moved in response to the movement of the eye.
It was developed in Fairfax, Virginia, by LC Technologies, Inc.,
With the help of an eye gaze system, people whose communication abilities are impaired can still express their feelings and needs with a limitless vocabulary.
