Abstract
Abstract This invention relates to an automated educational system in which a remote student or subject can be interrogated by a central automated interrogation system, can respond using machine-distinguishable signals generated by a Touch-Tone-type telephone, and in which an appropriate reaction to the answer chosen by the student can be communicated to the student.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
232 words
A remote interactive communication system comprised of: (a) a source location, (b) a subject location remote from the source location, (c) a telephone located at the subject location and adapted to generate a plurality of machine distinguishable signals, (d) an interface unit located in the source location, (e) a first communication link betwen the telephone and the interface unit, (f) a programmable controller located at the source location, (g) a second communication link between the interface unit and the controller, (h) a storage unit which includes a plurality of magnetically encodable discs, (i) a third communication link between the interface unit and the storage unit, (j) a fourth communication link between the controller and the storage unit, (k) a first initiating declaration file stored in the storage unit containing data adapted to be delivered in audible form to the telephone under supervision of the controller, the data including a response-inviting statement and a plurality of possible responses, each being associated with a different one of the machine distinguishable signals of the telephone, and (l) a plurality of reaction files stored in the storage unit, one of which files represents and is associated by the controller with each of the machine distinguishable signals when that signal is generated by the telephone over the first communication link, said one file being thereafter delivered in audible form to the telephone under supervision of the controller.
Claim 2
Dependent Claim
