Publication Date: September 2002
Article describing a British-designed software program called Dasher, which allows computer users with disabilities to “type” using only the gaze of their eyes. The program allows computer users to visually flip through an on-screen alphabet to consecutively select letters to form a word. The system can be controlled by a computer mouse, trackball, or an eye-tracking device that utilizes the user’s eye motions. The software also predicts the writer’s intentions to complete a word or phrase. Researchers have been able to write up to 25 words per minute, with the percentage of words misspelled below 5 percent.
