In the TV market, there is an increasing demand for a handheld pointing device which can recognize user handling motions in the air. As conventional pointing devices suffer from high cost, high power consumption, limited motions, or short operating distance, we propose an economic and efficient pointing device that is intuitive to use. In the proposed device, the transmitter generates two infrared (IR) signals, modulated by an optical filter and lens in front of each infrared light emitting diode (IR-LED), and the receiver estimates two-axis motion vectors from the two modulated IR signals and user handling motions.
