Abstract

Fourteen disabled persons used a one-hand chordic device for typing. This keyboard was designed to minimize physical exertion and to inhibit unwanted psychomotor reactions so as to facilitate its use by persons with cerebral palsy, muscular dystrophy, and related disorders. The keyboard fits the fingers of one hand. A character is typed by pressing a combination of fingers corresponding to a typing code developed earlier. Typing rates of text transcription ranged from 8 to 14 words/min after 5 h of practice. These results indicated that the physical configuration and cognitive operation of a chordic keyboard would permit disabled persons to use computers.
