A TV remote pointing device using LED directivity

As TV contents and its user interfaces become rich and complex, the demand for a more efficient pointing device is increasing. As a lightweight solution for this purpose, we present a remote pointing device using LED directivity. The main technical issues that we had to solve include the irregularity of LED directivity, sensitivity to ambient infrared noise, and cursor instability due to hand tremor. The results of a user test show that the final design is comparable with a gyro-mouse and a Wii Remote in terms of pointing throughputs and error rates despite its relatively simple and low-cost structure.
