The touch screen has attracted people's attention since its birth. In 1982, Knoxville, Tennessee, in the United States Pavilion at the World Trade Fair, exhibited for the first time 33 television sets using a new transparent touch-sensitive control panel. For many people, this was the first time to watch and use a touch screen.

In 1991, touch screens entered our country. At that time, it was only an agent of infrared and capacitive touch screen products from abroad. In 1993, my country's infrared touch screen technology was basically mature. During this period, the prototype of Kiosk, a touch self-service kiosk, was gradually produced. Although touch screen technology has only been applied in my country for more than 20 years, it has become a computer input method that is easily accepted by ordinary people after keyboard, mouse, handwriting pad, and voice input. Because using this technology, the user can operate the host by gently touching the icon or text on the computer screen with his finger, which makes the human-computer interaction more straightforward.

This technology greatly facilitates the user. Suitable for multimedia information query. At the same time, this kind of human-computer interaction gives multimedia a new look, and it is a very attractive new multimedia interactive device. In 19% of the year, my country's first self-developed touch self-service kiosk was born.

The launch of the iPhone in 2007 has become a milestone in the development of the touch screen industry. Apple designed a mobile phone that requires at least 20 buttons to require only three or four buttons, and all the remaining operations are completed by the touch screen. In addition to giving users a more direct and convenient operating experience, it also makes the appearance of the mobile phone more fashionable and thinner, increasing the intimacy of direct human-machine interaction, triggering enthusiastic pursuit of consumers, and opening the touch screen to the mainstream The control interface moves forward.

With the development of computer technology and network technology, touch screens are now widely used in point-of-sale POS self-service machines, information query equipment, entertainment equipment, computer-based training and simulation, medical equipment, mobile and handheld systems, industrial control It has penetrated into all aspects of people's lives in various fields such as equipment, office automation equipment, and information appliances. 

At present, the application range of touch screens has become more and more extensive, from industrial equipment control, operating systems, electronic inquiry facilities for public information inquiry, commercial cash machines, to consumer electronics mobile phones, PDAs, digital The touch screen can be seen from the camera. Of course, mobile phones are still widely used. According to a report by the research organization ABIResearch, the shipment of mobile phones with touch screens will exceed 100 million in 2008, and it is expected that the shipments of mobile phones with touch screens will exceed 500 million in 2012.

There are signs that the application range of touch screens in consumer electronics products is expanding from small size areas such as mobile phone screens to notebook computers with larger screen sizes. Currently, first-tier notebook computer brand manufacturers such as Dell, HP, Fujitsu, and Asus are planning to launch notebook computers or UMPCs with touch screens. Of course, there is still debate in the industry as to whether laptops equipped with touch screens can expand from low-priced laptops or UMPCs below 10 inches to mainstream laptops above 14 inches. Because for mainstream laptops or desktops, consumers have become accustomed to using keyboards and mice for input. Unlike small laptops, which can accommodate a limited number of keyboards, they need to be assisted by a touch screen to achieve a more intuitive The purpose of man-machine communication.

The current touch computers are mainly All in one desktop computers, and the industry has also launched a few multi-touch notebook computers to test the market response. Since the Windows 7 operating system directly supports multi-touch applications, compared to ordinary touch computers that only support single-finger operations on the screen, multi-touch computers can flip photos, graffiti, write, and adjust window operations with two fingers.
