An X-Y Platform for Randsight-Type Instruments.
Clewett, R. W.; And Others
A hand-operated mechanical device, called an X-Y Platform because of its ability to undergo orthogonal planar motions reminiscent of X and Y coordinates, permits design simplifications and lower costs when used with RANDSIGHT-type closed circuit television to enable the partially sighted to read and write. This paper presents a detailed discussion of the construction of the platform together with recommendations for its operation and use for both reading and writing. Features believed necessary for a high quality platform are summarized at the end. (Author/SH)
