触摸屏(Touch Screen),顾名思义就是以手指(或其它物体)接触显示屏对电脑进行操作的一种特殊设备。它的显示输出与控制输入均集中在屏幕上,作为一种典型的定位设备,它能模仿(替代)键盘及鼠标器操作,而使用简便、控制直观是其突出优点。如今,在很多公用场所(例如:超级市场、邮电大厅、银行前台、餐饮娱乐厅、股票、证券、外汇兑换咨询中心等)其身影随处可见。此外在电脑辅助教学(CAI)、多媒体演示系统及科学普及宣传方面也显示出良好的应用前景。
Touch Screen, as the name suggests, is a special piece of equipment used to operate a computer with a finger (or other object) touching the display. Its display output and control input are all focused on the screen. As a typical positioning device, it can mimic (replace) the keyboard and mouse operation, and its simple and convenient operation and intuitive control are its outstanding advantages. Nowadays, there are many public places such as supermarkets, post and telecommunications halls, bank front offices, restaurant and entertainment halls, stocks, securities and foreign exchange consulting centers. In addition, computer aided teaching (CAI), multimedia presentation systems and science popularization also showed good prospects.
