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.
