Abstract

Current infrared touch screens use mainly the image processing algorithm as multi-touch recognition algorithm, resulting in high probability of pseudo touch points and poor accuracy. A new multi-touch recognition algorithm based on computational geometry theories was presented. Practical experiments give positive results to support the present improvement.
