Abstract
A portable computer for wireless communication with peripheral devices over an infrared communication link. The portable computer is capable of automatically controlling an infrared signal direction for greater data transfer efficiency over the infrared communication link. The portable computer includes an input/output controller for outputting infrared signal transmission data according to an input command, receiving infrared signal reception data, and outputting an infrared refraction control signal according to whether the infrared signal reception data is received; an infrared signal transmitter for transmitting an infrared transmission signal according to the infrared signal transmission data to the peripheral device over the infrared communication link; an infrared signal receiver for receiving an infrared reception signal from the peripheral device and outputting the infrared signal reception data; and an infrared signal direction controller for controlling the direction of the infrared transmission signal to the peripheral device, and the direction of the infrared reception signal according to the infrared refraction control signal.
