Gravity induction is a humanized system, and its basic principle is to make corresponding program response due to the change of force direction and gravity acceleration. Nowadays, many mobile phones have joined this system, and there are both positive and negative comments, and the quality of which should be tasted by users. Of course, for 2008, gravity sensing is nothing new, but there is no doubt that the function of gravity sensing has been absolutely carried forward in 2008, covering almost all mobile phone products from 3G iPhone to shanzhai machine. Not everyone is used to the gravity sensing function. Take Samsung's new SGH-i900 as an example. When holding normally, the interface is a conventional vertical interface. When you rotate the machine 90 to the horizontal direction, the interface will also change to the corresponding horizontal interface according to the force sensing. This is the main application of gravity sensing: automatic switching between horizontal screen and vertical screen. Gravity sensing system is also mainly used in some music mobile phones, which is what we often call the shaking control function. As long as the user wants to change to the previous or next piece of music, he can do it by gently shaking the phone, and then he can play it automatically and randomly by shaking it back and forth. The application of this gravity sensing system is the perfect combination of technology and fashion. Rock songs are more fashionable. Other applications: gravity-sensitive games, such as avoiding small holes, fishing, craps and other game programs that conform to the principle of gravity. If you install some software, you can also measure the inclination angle of the horizon and other interesting small functions. The basic principle is that the corresponding program is made due to the change of force direction and gravity acceleration.
