    Abstract: An identification method for simultaneously identifying multiple touch points on a touch screen, which includes the following steps: a first step, mounting some optical signal transmitting terminals and some optical signal receiving terminals around the touch screen; a second step, when some touch points appear on the touch screen, performing horizontal and vertical scans to get a preliminary location region; a third step, performing maximum positive inclination revising on the preliminary location region in the second step; a fourth step, performing maximum negative inclination revising on the region in the third step; a fifth step, some said optical signal transmitting terminals transmit optical signal in turn, inclination corresponding receiving terminals correspond to some said optical signal transmitting terminals are controlled in a receiving state in turn; a sixth step, filtering the locations of touch points in the fifth step, removing error points off, finally determining the location results of some said touch points, and finishing the whole identification process.

    Abstract translation: 一种用于同时识别触摸屏上的多个触摸点的识别方法,其包括以下步骤:第一步,在触摸屏的周围安装一些光信号发射端和一些光信号接收终端; 第二步,当触摸屏上出现一些触摸点时,执行水平和垂直扫描以获得初步位置区域; 第三步骤,在第二步骤中对初步位置区域进行最大正倾角修正; 第四步,在第三步中对区域进行最大负倾斜修正; 第五步,一些所述光信号发射端依次发送光信号,对应于一些所述光信号发射端的倾斜对应接收端依次被控制在接收状态; 第六步骤,在第五步骤中过滤接触点的位置,消除误差点,最后确定一些所述接触点的位置结果,并完成整个识别过程。
