This disclosure is for an Audio-Visual training device having both a projectable film tape and an audio tape with control indicia on the audio tape in addition to recorded audio messages. The tape indicia are used to control a small processor which governs both tape and film movement. A keyboard on the device is used to enter replies to queries to a user from the tape and film and the processor will determine both tape and film movement in response to the answer to a query. The system is capable of multiway branching to present to the viewer the proper information pertaining to his answer. Several counters are available to count trials, correct or incorrect responses, etc., and to control tape and film movement in accordance with the counter readings. A proctor light may be turned on to call for personal assistance and to lock up the machine when a student is in trouble and the program does not have the proper branch to clear up the difficulty.
