A Second-Generation Interactive Classroom Television System for the Partially Sighted.
Genensky, S. M.; And Others
The interactive classroom television system (ICTS) that is described permits partially sighted students and their teachers to be in continuous, two-way visual communication. It was implemented in Rowland Heights, California, as part of the second phase of a project aimed at evaluating how the ICTS helps in teaching basic skills to partially sighted elementary school children in classroom settings. The first of two sections describes the function and operation of the system, which comprises eight stations, a master control unit, a room-viewing camera and control unit, a videotape recorder, and color TV monitor/receiver. Section 2 considers the design and electronic implementation of the ICTS, with emphasis on how the electronics are arranged and operate. Included are the overall organization of the system, the input/output board, the video and audio switching systems, synchronization, keyboard logic, and maintenance information. Appendix A gives detailed instructions for using the unit, and step-by-step instructions for coping with system failures are listed in appendix C. Three references are listed. (Author/LMM)
