Abstract

A method and apparatus for producing an interactive video drama employing a personal computer, a voice recognition device, and a programmable videodisc player. A plurality of dramatic scenes are stored on a videodisc and displayed to the user in response to spoken commands. At certain scenes designated as decision points, the next displayed scene is selected based on a probability technique. By storing audiovisual representations of a speaking human being and by selecting scenes for display based on spoken input signals, the apparatus provides the illusion of dialog between a user and prerecorded human characters.
