| Abstract: | On the basis of the infrared touch screen hardware, this paper summarizes the infrared touch screen three scanning methods, focuses on the tilt scanning algorithm analysis and research, and give the tilt scanning algorithm model. Through mathematical tools MATLAB simulation of the model, tilt scanning algorithm that can reduce the density of the element, to eliminate orthogonal sly points, and not to extend the scan time, not only to ensure the performance of the infrared touch screen, but also reduces the cost of the infrared touch screen. |
