The types of personal computers in most widespread use have been adapted by the author for the use of blind and speech-handicapped users by the addition of unlimited vocabulary speech output, Grade II braille output, and Morse code input for the physically handicapped. Experiments are under way with multifont optical character recognition input and are planned with portable electronic typewriter input. Field tests have shown that personal computers can provide low-cost aids to blind users in study, employment, and recreation.
