tronic devices. After the task has been ful?lled, the electronic
system updates the data to re?ect the modi?ed state of the
external electronic devices.

1. Field of the Invention
The present invention relates generally to remote control

Remote control devices have been in use for years. Remote

typically comprised of a housing structure, a keypad Within

In these respects, the state-based remote control system
