Paper Abstract

At least 500,000 profoundly deaf persons in the United States communicate primarily by American Sign Language (ASL), a language quite distinct from English and not well suited to writing. Currently, telephone communication for an ASL user is basically limited to use of a teletype machine, which requires both typing skills and proficiency in English. This paper reviews recent research relevant to the development of techniques which would allow manual communication across existing telephone channels using video imagery. Two possibilities for such manual communication are ASL and cued speech. The latter technique uses hand signals to aid lip reading. In either case, conventional television video transmission would require a bandwidth many times that available on a telephone channel. The achievement of visual communication using sign language or cued speech at data rates below 10 kbps, low enough to be transmitted over a public telephone line, will require the development of new data reducing algorithms. Avenues for future research toward this goal are presented.
