随着计算机技术的发展，计算机的输入方式由原来的纸带输入到键盘输入、到鼠标输入、再到触摸输入，共经历了四个阶段。这个过程是一个普及的过程，触摸屏技术让更多的人使用上了计算机。触摸屏是一种交互输入设备，用户只需用手指或光笔触摸屏的某位置即可控制计算机的运行。因此，触摸屏技术具有操作简单，使用灵活的特点。 

自1960年美国早开启了研究触摸屏技术的大门，先应用于美国的军事。1972年美国 PLATO（Programmed Logic for Automated Teaching Operations）项 目首先推出一款触摸屏，用于计算机辅助教学，随着触摸屏的技术 越来越进步，其应用也越来越广泛，银行、车站、学校处处可见其身影，中国已经成为触摸屏为广泛的使用者。 [9] 随着电子技术、网络技术的发展和互联网应用的普及，新一代触摸屏技术和产品相继出现，其坚固耐用、反应速度快、节省空间、易于交流等许多优点得到大众的认同。 

渐渐地，这种为轻松的人机交互技术已经被推向众多领域，除了应用于个人便携式信息产品之外，还广泛应用于家电、公共信息（如电子政务、银行、医院、电力等部门的业务查询等）、电子游戏、通讯设备、办公室自动化设备、信息收集设备及工业设备等等。触摸屏技术在我国的应用虽然只有十多年的时间，但是它已经成了继键盘、鼠标、手写板、语音输入后为普通百姓所易接受的计算机输入方式。利用这种技术，用户只要用手指轻轻地触碰计算机显示屏上的图符或文字就能实现对主机操作，从而使人机交互更为直截了当。这种技术方便了用户，成为富吸引力的全新多媒体交互设备。
