What is multi-touch of mobile phone?

Edit this multi-touch mobile phone multi-touch is that the system can operate the corresponding operators on the screen at the same time. Multi-touch mobile phone is realized by using capacitive touch screen. Touching the screen of a mobile phone can be divided into capacitive and resistive types. The capacitive screen mobile phone represented by iphone can be multi-touched, but the capacitive mobile phone is greatly affected by temperature and has drift. The resistance screen mobile phone represented by N97, the screen can only confirm the operator's touch at one time, while the iphone has more than three points. Edit the definition of multi-touch in this paragraph. The traditional touch screen can only judge one touch point at a time. If you touch more than two points at the same time, it will not be able to respond correctly, or it will react confusedly. The task of multi-touch can be divided into two aspects: one is to collect multi-point signals at the same time, and the other is to judge the meaning of each signal, which is gesture recognition. Edit this multi-touch application If you have used the iphone, you will know that multi-touch is a very useful and fun thing: when browsing the web, you often have to enlarge a certain area to see clearly, and it is also very useful when looking at pictures. Of course, without this function, human beings can adapt to and achieve their goals. Just like a mobile phone without touch function, they are still surfing the Internet. Of course, simplicity and comfort are different. This is the same reason that eating meat and vegetables can fill your stomach. Many people think that multi-touch is limited to zooming in and out. In fact, zooming in and out is just one of the practical application examples of multi-touch. With multi-touch technology, how to apply it can be infinitely expanded through infinite imagination. Programmers can apply multi-touch to many aspects and change or innovate more operation methods to some extent. The typical application is that playing the piano on hard glass becomes a reality. If you turn the screen of your mobile phone into a keyboard, it's still very interesting to coax a little girl. Another typical example is the PS simulator on Apple's mobile phone, which realizes the simultaneous input of direction keys and other buttons through multi-touch technology.
