一种基于曲率计算的简便触摸定位方法
An efficient approach to capture touch point on the large touch screen based on curvature
摘要
Abstract
A human-machine interaction technology combined IR-pen(pen with IR) and large screen is introduced in practical application. It is inaccurate to detect the touch point during the pen is not vertical with the touch screen. In the paper- an efficient approach to detect the touch point about the touch apparatus is proposed, which can be used to solve the problem, no matter the pen is vertical with the screen or not. The new method does not influenced feasibility of the touch response. The experimental results show a good capability of detection and localization.关键词
