In 1971, the American Samhurst invented the world's first touch sensor. Although this instrument is not the same as the touchscreen we see today, it is seen as the beginning of a touch screen technology development. Samhurst, who worked as a teacher at the University of Kennedy when he was patience to deal with a lot of graphic data every day, began to figure out how to improve his work efficiency and use the simplest way to get the graphics done. He transformed his three basement into a workshop, one for processing wood, one for manufacturing electronic components, one for assembling the parts, and finally for creating the first touch screen. The earliest touch screen was named "Accutouch", as it was hand-assembled and produced several devices a day. In 1973, the technology was selected by the American Journal of Industrial Research as one of the 100 most important new technology products of the year. Soon, Samhurst established its own company and cooperated with Siemens to continuously improve the technology.
Until 1982, Sam Hurst's company exhibited 33 sets of touch-screen televisions at a technology fair in the United States, the first time the civilian population had "touched" the magic touch screen.
Touch screen technology who invented _ touch screen technology development process Since then, touch-screen technology has been widely used in public service areas and personal entertainment equipment.
People gradually used to "touch" the way, in the electronic vending machine to buy goods, karaoke machine on-demand songs, in banks, hospitals, libraries, airports to inquire about their needs. Early touch screen is installed in industrial or commercial equipment such as computer, POS terminal and so on. The launch of the iphone in 2007 has been a milestone in the development of the touch industry. Apple's mobile phone, which requires at least 20 keys, is designed to take three or four keys and the rest is left to the touch screen. In addition to giving users a more direct and convenient operation experience, but also make the shape of the mobile phone more fashionable and light, increase the intimacy of human-machine direct interaction, triggering a warm pursuit of consumers, but also opened the touch screen to mainstream control interface to the journey.
