Abstract: An electronic audio-visual teaching system employing essentially a cathode ray tube and associated electronic apparatus and a transparent manually operated spatial response signal generator which coacts with the cathode ray tube whereby feedback between students and teaching machine is readily achieved. Provides considerable ease in programming. Also can be used for remote polling of viewers.
