Abstract

A vending machine adapted to reproduce audio and video messages relating to the products being dispensed. The video portion of the message is produced by a video synthesizer which displays objects which are animated in response to the audio message. For example, a human-like face can be synthesised, the lips of which move in response to speech being replayed. The vending machine can also be a music juke-box.
