Abstract

Telephone DTMF keypad signalling is converted to a unique user input protocol in conjunction with interactive media and telecomputing network systems to permit one or more participants to provide directional, triggering, and other input to computer or computer controlled systems with telephone keypads or like devices as if using a computer system mouse, joystick, keyboard, or similar input device. Such utilization of readily available push-button telephones as a participant'"'"'s computer input device, permits user interaction with computer generated, influenced, or controlled video programming, databases, and applications providing visual feedback over a video network.
