Abstract

Disclosed herein is a wireless interactive presentation system that operate in cooperation with a host computer system executing PC compatible application programs capable of generating and displaying text, image and graphic content on a projector or presentation device. The wireless interactive presentation system also includes a wireless data transceiver capable of communicating and exchanging application or system commands and data with a network-based computer system. The wireless interactive presentation system comprises a micro-controller, an infrared receiver and a wireless transceiver to provide short-range communication between the remote system and wireless interactive presentation system. The microcontroller of the wireless interactive presentation system executes a control program to process the commands and data received from remote computer via the wireless transceiver and provides the resultant application window, template, or graphical display data to projector or presentation device.
