A low-cost, absolute pointing device for the TV exploiting the directivity of LEDs is presented. The main technical issues to solve were 1) the irregularity of the directivity of LEDs, 2) susceptibility to external infrared noise, and 3) instability due to hand tremor. The efficiency of the prototype was evaluated in comparison with GyroPoint and Wii remote.
