You run the system with your eyes. Eyegaze Systems are being used in homes, offices, schools, hospitals, and long-term care facilities. The above picture shows Joe Martin, who has ALS, using his Eyegaze System at his office in North Carolina. As a user sits in front of the Eyegaze monitor, a specialized video camera mounted below the monitor observes one of the user's eyes. Sophisticated image- processing software in the Eyegaze System's computer continually analyzes the video image of the eye and determines where the user is looking on the screen.
Nothing is attached to the user's head or body.
A user operates the Eyegaze Communication System by looking at rectangular keys that are displayed on the control screen. The gaze duration required to visually activate a key, typically a fraction of a second, is adjustable. An array of menu keys and exit keys allow the user to navigate around the Eyegaze programs independently. The Main Menu appears on the screen as soon as the user completes a 15-second calibration procedure. The Main Menu presents a list of available Eyegaze programs.
