You're no stranger to using touch screens, but few understand how they work. In the future, our lives will be replaced by touch screens, since touch screens should be aware of it, and more about it.
Touch screen (touch screen), also known as "touch screen", "touch panel, touch is a kind of can receive the first input signal of induction type liquid crystal display device, when contact with the graphic buttons on the screen, the screen of the tactile feedback system according to the program of pre-programmed drive all kinds of connecting device, can be used to replace the mechanical button panel, and liquid crystal display screen by creating vivid audio effect. As the latest computer input device, touch screen is the simplest, convenient and natural way of human-computer interaction at present. It gives multimedia a new look and is an attractive new multimedia interactive device. It is mainly used in public information inquiry, leading office, industrial control, military command, electronic games, song ordering, multimedia teaching, real estate pre-sale, etc.
The so-called touch screen, from the market concept, is a kind of computer input device that everyone can use, or people can use to communicate with the computer. Without learning, everyone will use it, the biggest magic of touch screen, which neither keyboard nor mouse can compare with. Everyone can use it, which marks the true arrival of the popularization of computer applications. This is also the reason for developing the touch screen, developing the KIOSK and developing the KIOSK network, and striving to form China's touch industry.
From the perspective of technical principle, touch screen is a set of transparent absolute positioning system. First of all, it must be transparent. Therefore, it must solve transparent problems through material technology. Secondly it is absolute coordinates, finger touch which is which, don't need the second action, unlike the mouse, is a set of relative positioning system, we can notice that the touch screen software don't need a cursor, a cursor instead affects the user's attention, because the cursor is for relative positioning device, relative positioning device to move to a place where the first thing to know, which direction to go, all the time also need to constantly feedback to the user's current location is not appeared deviation. None of this is necessary for a touchscreen that USES absolute coordinate positioning; Then there is the ability to detect finger touch movements and determine finger position. All kinds of touch screen technology is based on "detect finger touch".
