Abstract
A remote control device has one or more accelerometers for measuring a vertical acceleration and a horizontal acceleration caused by an operator gesturing with the device. Signals from the accelerometer enter a microcontroller and used to determine a gesture type; the microcontroller then generates an encoded command appropriate to a device to be controlled and broadcasts it with an infrared transmitter. The microcontroller distinguishes at least LEFT, RIGHT, UP, and DOWN gestures, and at least one gesture type causes the microcontroller to generate VOLUME UP commands with another gesture type causing the microcontroller to generate VOLUME DOWN commands. Additional embodiments distinguish clockwise and anticlockwise rotary gestures and assign them to appropriate commands. Embodiments for use with television reception have gesture types that generate CHANNEL UP and CHANNEL DOWN commands, while embodiments configured for use with DVD and VCR players and recorders have gesture types that generate PAUSE and PLAY commands.
