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.
