A Closed Circuit TV System for the Visually Handicapped

Samuel M. Genensky, Paul Baran, H. L. Moshin, H. Steingold

ResearchPublished 1968

A description of an inexpensive, experimental closed circuit TV system that can help the visually handicapped to read, write, or perform precise manual operations. The system is of potential value to any partially sighted person who has difficulty reading and writing even with eyeglasses, but who would be helped by a visual aid that increases magnification, brightness, or contrast, or a combination of these factors. The prototype system consists primarily of (1) a TV monitor resting on a shelf, which can be moved toward or away from the user and raised or lowered slightly for convenience; (2) a TV camera that can be rotated about a fixed but arbitrary horizontal axis by means of an electrically operated servomechanism; and (3) a working surface used to support reading and writing materials. The hardware for this instrument costs less than $1000. A modification of the prototype system, produced commercially, could be of value to visually handicapped people in schools, at work, and at home.
