Advances in Closed Circuit TV Systems for the Partially Sighted
ResearchPublished 1972
Two RAND-designed CCTV systems called RANDSIGHT I and II, which permit the partially sighted to read printed material or write with pen or pencil, are described. CCTV systems are of value to over 800,000 partially sighted Americans. A testing program involving partially sighted subjects using RANDSIGHT I with an X-Y Platform is described and results are given. The RAND X-Y Platform (described in detail) has revolutionized design and lowered cost of similar commercial systems. In RANDSIGHT II, a research instrument, the motor-driven camera, scans a line of text automatically or under foot or hand control. Tests indicate that no X-ray hazard exists from monitors operating at acceleration voltages not exceeding 19 kv. A simple lightbox test for determining roughly whether a CCTV system will benefit the partially sighted, and which can be administered in a physician's office, is presented. A comprehensive list of criteria for constructing a rationally designed CCTV system is given. (The word RANDSIGHT is the Certification Mark of The RAND Corporation.)
