Abstract

An audio-visual, virtual-reality system making it possible for a user to see, during successive time periods, a still image of a particular subject while listening to a program relating to that subject. The system consists of a standard record player coupled to a viewer unit, the record player being provided with a loud speaker and an output jack to both of which are fed the reproduced signals of the recording being played. The record carries a sound recording of a series of programs, each related to a different subject, each program being preceded by a supersonic cue signal. Inserted in the viewer unit is a film storage device containing a series of film frames, each having an image of a subject corresponding to a respective program of the recording. The unit includes a stepping motor to advance the frames so as to present them successively to the eyes of the user, and a control circuit for the motor responsive to cue signals yielded at the output jack of the player. The motor is activated each time a cue signal is received to present the next frame in the series. The arrangement is such that when a particular program is heard by the user, he is at the same time viewing the image of the subject to which this program is related.
