A CLOSED CIRCUIT TV SYSTEM FOR THE VISUALLY HANDICAPPED AND PROSPECTS FOR FUTURE RESEARCH,

Abstract

The CCTV system has several important features, namely (1) it is both a reading and writing device, (2) it incorporates variable magnification (from 1.4x to 31.7x using a 9 inch monitor), (3) it permits the reader to track printed or handwritten material across a line, (4) it allows the user to adjust the position of the monitor for his convenience and (5) it permits the user to change the vertical plane of rotation of the camera--a maneuver which is necessary if the writing habits of the individual are to be taken into account.
