Abstract

An electronic presentation system is presented utilizing a wireless remote for controlling a digital computer, one or more display or storage/playback devices and an audience response system. A Terminate and Stay Resident (TSR) program within the digital computer manages the wireless remote. The digital computer running the TSR program enables the wireless remote to operate any applications program, as well as to use the computer to add spontaneously certain special effects to the presentation and to control an audience response system. In addition, the computer downloads into the wireless remote control, via a wireless communications link, data commands and signalling parameters such as modulation scheme and communications protocol with which to enable the wireless remote to generate the correct signalling to operate predefined display or storage/playback device.
