Problems solved by technology
The capacitive touch screen itself is a planar sensor with a touch IC inside, and it is located on the outermost layer of the mobile phone. The input operations are all on the touch screen, so long-term touch operations will cause serious wear and tear on the touch screen. Generally, the life of a mobile phone is determined by The life of the touch screen is determined, as long as the touch screen is broken, the mobile phone will not be able to use directly

The invention discloses a method, system and mobile terminal for realizing a simulated touch screen by using a sensor, wherein the method includes the steps of: A, loading a device driver for a simulated touch screen, and adding a key response method for physical keys and an interface for acquiring acceleration sensor data; B. Obtain the data of the acceleration sensor through the interface, obtain the movement data of the coordinates according to the data of the acceleration sensor, and determine and report the coordinates or report the click event according to the click state of the physical button. The present invention obtains the data of the acceleration sensor, calculates and obtains the positioning coordinates, and simulates the position change of the human hand moving on the touch screen or above the touch screen. All operations of the single-point touch screen can be realized through the present invention, that is, the function of simulating the touch screen can be realized. In actual use, after the simulation function is activated, various functions can be realized directly by tilting the mobile phone and clicking physical buttons without operating the touch screen.
Description
technical field [0001] The present invention relates to the technical field of mobile terminal touch, in particular to a method, system and mobile terminal for realizing a simulated touch screen by using a sensor. Background technique [0002] At present, mobile terminals such as smart phones generally give up full keyboards and resistive touch screens, and mostly use capacitive touch screens. The capacitive touch screen itself is a planar sensor with a touch IC inside, and it is located on the outermost layer of the mobile phone. The input operations are all on the touch screen, so long-term touch operations will cause serious wear and tear on the touch screen. Generally, the life of a mobile phone is determined by The life of the touch screen is determined. As long as the touch screen is broken, the mobile phone will not be able to be used directly. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of...
