viewsonic 55 inch touch screen.Concept : The so-called touch screen is, from the market concept, a computer input device that everyone uses, or a device that everyone uses to communicate with a computer. No need to learn, everyone will use it. It is the biggest magic of touch screen. No matter it is keyboard or mouse, it can't be compared with it. Everyone can use it, which means that the era of computer application popularization has come. This is why we develop the touch screen, KIOSK , KIOSK network, and strive to form the Chinese touch industry.??From the perspective of technical principles, the touch screen is a transparent absolute positioning system. First of all, it must be transparent, so it must solve the problem of transparency through material technology. Like digitizers, writing boards, elevator switches, they are not touch screens. ; Secondly, it is the absolute coordinate, which is where the finger touches, no second action is required. Unlike the mouse, it is a relative positioning system. We can notice that the touch screen software does not need a cursor, and the cursor will affect the user. Attention, because the cursor is used for relative positioning devices. To move a relative positioning device to a place, you must first know where it is and in which direction. You also need to keep giving users the current feedback at all times. The position is not deviated. These are not needed for touch screens that use absolute coordinate positioning; secondly, they can detect the touch of a finger and determine the position of the finger. Various touch screen technologies are based on " detecting finger touch " and the eight immortals cross the sea.??The first feature of the touch screen: transparency, which directly affects the visual effect of the touch screen. There is a problem with the degree of transparency. The infrared technology touch screen and the surface acoustic wave touch screen are separated by a layer of pure glass. Transparency can be regarded as the best. Other touch screens must be carefully considered. " Transparency "
