Abstract: In a fully flexible interactive program, options are presented to the user by means of a projected slide. When one option is selected, and is entered into the machine, a preconditioned memory energizes a servomechanism to advance a select one of plural videotape recorders to a particular segment. The servo controls the tape advance by comparing distance to go with a signal proportional to the square of the tape velocity. When the segment is reached, the videotape presents an audiovisual segment to the user, during which time information for subsequent options to be presented is coupled into the system, including identification of the next option slide to be presented and video segment identification corresponding to those options for preconditioning the memory.
