Abstract: Improved audio-visual display systems are disclosed. A lesson program in audio frequency form recorded on a storage medium provides control data and narrative information. The control information provides data to the system about the particular lesson program, including the visual images which are to be associated with the narrative information. The control data also provides information concerning the responses expected from users of the system, and instructions for alternative steps available which are prescribed in accordance with a users actual responses. The lesson program may be arranged in chapters which include control data and corresponding narrative information. Separate visuals may be provided, with images indexed for selection by the control data.
