Abstract
An apparatus controls electronic devices, via radio frequency (RF) transmitter and receiver for communication between the apparatus and a user, a central processing unit (CPU) executing software for handling the conversion of an RF signal from the user into a two dimensional location (an X, Y coordinate system) and conversion into a series of remote control commands for transmission to a series of devices equipped for remote control. The user can control the electronic devices of an electronic system, for example a home entertainment system (which might include, by way of example, a television, a DSS or satellite receiver, a CD player, a video recorder, a video disc player, a radio tuner, an amplifier, a tape deck, an audio video preamplifier or a combination of one or more of the foregoing). The CPU also executes software which digitizes real time video and combines it with computer graphics for display.
