Abstract

A novel human-computer interaction (HCI) system based on real-time image processing is proposed in this paper. With the help of infrared tracking technology, the proposed system achieves real-time processing and stable operation on an ADSP-BF533 hardware platform. Compared with the conventional remote control methods, the proposed system enables a user to control the cursor on the screen of a TV by targeting it, and provides users with new experiences of remote control. To realize such a new remote control system, cross-ratio invariant, which is an important characteristic of the projective transformation, is also studied. Experimental results show the potential of the proposed system in TV remote control.
