[Prior Art] In the history of electronic devices, keyboards, mice, and touchpads appeared to solve input control problems. However, for beginners, learning to use these input interface rights is not a small space, for example, half of the volume of a notebook or mobile phone is keyed. If you can save the keyboard to find, the self-healing upgrade product can be carried, and the feasible way is to operate directly on the panel by touch. Therefore, 'the application of Pointing Stick and T〇uch Pad technology has a wide range of application requirements, and it is hoped to replace the traditional mouse and keyboard operation functions, because the gesture language is simple. And no (four) misunderstanding, - some academic research institutions began to develop technology that can rely on gesture language, so that the touch panel is humanized, and the user can use the same finger to reach the highest level of hand touch. The development of touch technology has actually been going on for a long time. However, since the launch of 1PhQne, it has cast a shock bomb for the touch market. The electronics industry has learned that the touch screen is not just a niche market, but it is enough to become a mainstream input interface. The iPhone proves that a good touch interface can really replace most keyboard functions' and give users a more intuitive and convenient operation experience; instead of a keyboard with a larger 3 panel, it can also be designed to be thinner and more stylish; Fully adopt solid-state panel technology, no need to worry about mechanical parts failure such as keyboard, pulley, etc. IT products will step into the new era of multi-touch (Multi-touch). Although it can use the resistor/capacitor type to build a home-controlled gate computer, the number of touch points in this mode cannot be many, and it is less suitable for multiple users. Users use at the same time. The newer technology is built using a charge-coupled component (CCD) to capture computer vision. In addition to the number of touch points, it is not limited to a single user's ability to allow multiple fingers and other ways. And the New Zealand dollar _ (four), _ M base T 〇 ^ h the highest realm, its application space will be infinitely broad. At present, the touch-compatible mode has been developed in the "computer operating system", so all the industry players are competing for the development of gesture recognition, and it is necessary to define different (four) gestures. The more the touch screens are closed, the faster the technology development is. iPhGne adopts the projection f-capacity technology to realize the multi-touch function, so that everyone can turn their attention to the new touch technology. Inspire the touch glory to face more difficult to reciprocate, the rich and powerful technology is in Wei, including capacitive, surface acoustic wave and photoelectric scale. Due to the increased speed of imaging and image discrimination in recent years, the image light screen has been emphasized, and many manufacturers have proposed new experimental systems or products. The current product and the c〇mputing published by Microsoft. Both use infrared light and brightly touch the finger or contact with the screen, and then use the infrared camera (10) C_ra) to capture the image to achieve the goal of simultaneous multi-touch interaction.

Calculate the position of the palm's hand. It is necessary to have a quasi-selling calculation level. In the early days, the operation principle of electronic white (four) was to arrange the LED light source on the frame, and add the homogenizing film (returning to increase the hook degree of the frame light source, but this view should be controlled to have the brightness of the image. The structure of the re-evolution is to add a reflective strip to the screen border to reflect the light source of the shot to _ flashing red. When the finger enters the detection mode _shadowing effect, the city is „block’ hunting to calculate the finger Location, but this mode of operation must be verified in every environment of light: the accuracy is in the environment where the scene is too dark, the hanging frame is not bright enough ^ there is distortion; to improve the distortion 5 Also on the frame, the hard-installed head is set with LED illumination, which will cause the finger to become a bright spot when it is close to the 2 source, and it will become a dark spot when it is far away from the light source, so that there will be a good time when the age is calculated. It can be seen that the gestures of displaying screens are the places that various touch systems strive for, but the reflective light source that determines the success or failure has also received considerable attention.
