Abstract

In this work, we present a complete architecture to implement a dual touch function for large sized displays. The architecture includes the hardware device and the software algorithm. The system has lower cost and smaller size than previous works for large sized display. And the proposed approach eliminates the requirement of special hardware. The system can be plugged to a normal display and change the display to equip the dual touch function. At the final of this paper, we give an experiment to demonstrate the system and show its usability.
