随着计算机技术的普及,在20世纪90年代初,出现了一种新的人机交互作用技术——触摸屏技术。利用这种技术使用者只要用手指轻轻地碰计算机显示屏上的图符或文字就能实现对主机操作,这样摆脱了键盘和鼠标操作,使人机交互更为直截了当。因此,触摸屏技术已成为当前最简便的人机交流的输入设备。 With the popularization of computer technology, in the early 1990s, a new technology of human-computer interaction-touch screen technology emerged. Using this technique, the user can touch the icon on the screen of the computer by gently touching the icon on the screen of the computer, so that the user can get rid of the operation of the keyboard and the mouse to make human-computer interaction more straightforward. Therefore, the touch screen technology has become the most convenient human-computer communication input device.
