The Eyetracker, a device that precisely monitors eye movement, can determine the direction of person’s gaze over a large, two-dimensional visual field with great accuracy and without attachments on the eye. It can be used in many applications, including cognitive and neurologic investigations, medical research, communication systems for the disabled, laser refractive surgery, web usability, and even to analyze the effectiveness of advertising materials.
The Eyetracker was under continuous development at SRI through 1988. Many monocular and binocular systems were built at SRI for vision laboratories across the U.S. and abroad. In 1988, the technology was licensed to Fourward Technologies, which continued its development and marketing and installed Eyetrackers all over the world.
