摘要

提出了一种新的触摸信号数字处理算法。在判断红外发射端和接收端之间是否存在红外光束的过程中，考虑了误差概率的计算。误差概率由以下函数计算:(a)在触摸界面中心前方放置一定距离的反射器模拟的环境照度;(b)处理触摸信号的算法中实现的窗口函数。计算了一些经典的时间对称窗函数和一些原始的时间不对称窗函数的误差概率。

Digital processing of touch signal - error probability

A new algorithm for digital processing of a touch signal is proposed. We consider the calculation of the error probability in the process of deciding on the existence of the optical infrared beam between the infrared transmitter and receiver. The error probability is calculated in the function of: (a) the ambient illumination simulated by the reflector placed a certain distance in front of the center of the touch interface; (b) window functions implemented in the algorithm for processing of the touch signal. The error probability is calculated for some classical, time-symmetrical as well as for some original, time-asymmetrical window functions.
