1. Optical touch screen
In principle, the optical touch technology is a new technology that is different from the existing infrared, surface acoustic wave, resistance, capacitance and other touch technologies. The optical sensor responds quickly to detailed actions, making the application lighter, smoother and more accurate! But in fact, the optical screen cameras on the market today are too bad! Optical touch is to rely on the two camera heads on the left and right to emit light to sense the contact points on the screen to form a touch. Today's optical screen cameras are far from meeting the requirements for its application in principle. There are blind spots and false point touches (inaccurate touches are false points), which is the status quo of optical touch. The camera used for optics is difficult to meet the requirements on the principle. As a result, the screens on the market still stay three years ago, and there is no advanced technology to improve it. There are almost no manufacturers in production. In a word, the principle of optical touch is very powerful, but technology can't do it yet! The market technology is not yet mature!
2. Infrared touch screen
The principle of infrared touch is to emit XY lines through an infrared light tube, and the touch point is the sensing coordinate. The advantages of infrared touch: (also the application status on the market today) high stability, will not drift due to changes in time and environment. Free from current, voltage and classic interference, suitable for harsh environmental conditions (dust-proof and explosion-proof), long service life, high durability, not afraid of scratches, long touch life and good use characteristics, no force is required to touch, and no special requirements for the touch body.
Although a machine can never replace excellent personal customer service, the high-definition touch all-in-one machine can reduce the waiting time and allow consumers to complete the required services independently. Altron International Digital Signage has powerful system functions and rich intelligent interactive applications, and has been widely used in many industries. Using high-definition touch all-in-ones in casinos can provide consumers with customer information, fast restaurant and spa reservations, and performance tickets. Assuming that customers are frustrated by the long wait, you can think of how high-definition touch all-in-ones can help provide a better in-store experience.
