    Abstract: A remote response system utilizes portable response devices that receive user input and transmit user input over existing communication systems. Certain response devices communicate over wireless systems such as paging systems, while other response devices communicate over plain old telephone systems by sending data bursts or by dialing different, established telephone numbers. A user of a remote response device can communicate with a presenter of programming that is broadcast over audio/visual mediums in real time without requiring a personal computer.
