An audiographic system for self‐instruction

Journal of the American Society for Information Science, 1973, vol. 24, issue 6, 405-412

Abstract: The paper reports on the development of a system for the storage and retrieval of graphics‐supported, narrative presentations such as blackboard lectures. Human voice and line graphics are stored synchronously as analog signals on stereophonic audio tape, and reproduced via an “audiographic terminal” consisting of a loudspeaker (for voice output) and an electromechanical stylus (for output of line graphics). A configuration of audiographic terminals connected by telephone to a remotely located “bank” of instructional materials stored in audiographic form comprises the self‐instruction system ALF (Audiographic Learning Facility) developed and in use at the School of Information and Computer Science of the Georgia Institute of Technology. The paper describes several current applications of audiographic technology in education, and it gives preliminary cost estimates.
