Multi-Touch Recognition using Divergence Beam on Large-sized LCD

摘要

This paper proposes a multi-touch recognition technology which can be applied to large-sized LCD. To achieve this goal, a set of IR LEDs and sensors is used to construct an IR matrix, and a new algorithm based on Hough transform is applied. This approach reduces multi-touch noise compared to other IR touch recognition technologies, and shows robust performance on multi-touch recognition.
