    • Apparatus and methods are provided for converting a display into a touch display. One or more optical sensors are arranged proximate the display. A processor receives a signal from the optical sensor(s) and, based on the signal, executes instructions for: (i) determining a distance between a pointer device and a surface of the display signal; (ii) determining a position of the pointer device on the surface of the display; (iii) when the distance is less than a threshold detection distance and greater than a threshold touch distance, providing an indication on the display that the position of the pointer device has been determined; and (iv) when the distance is less than the threshold touch distance, taking an action indicative of contact between the pointer device and the surface of the display.
    • 提供了用于将显示器转换成触摸显示器的装置和方法。 一个或多个光学传感器布置在显示器附近。 处理器从光学传感器接收信号,并且基于信号执行以下指令:(i)确定指示器装置与显示信号的表面之间的距离; (ii)确定指示器装置在显示器表面上的位置; (iii)当距离小于阈值检测距离并且大于阈值触摸距离时,在显示器上提供已经确定指示器装置的位置的指示; 以及(iv)当距离小于阈值触摸距离时,采取指示指示器装置与显示器表面之间的接触的动作。
