Abstract: A wearable computer communicates with its display device via an optical link. The optical link may utilize different coloured LEDs and corresponding photodetectors for transmitting and receiving the video and control signals to and from the computer and the hand-held display package. The wearable computer may communicate with a local area network by a radio communications link. The use of two antennas mounted and associated with the wearable computer eliminates any gap within a propagation pattern emanated from the antennas.
