Method and device for avoiding misoperation by fingerprint confirmation, and mobile terminal

Abstract

The invention discloses a method and a device for avoiding a misoperation by fingerprint confirmation, and a mobile terminal. The method comprises the following steps: obtaining operation instruction information input by a user; judging whether the operation instruction information has a mapping relationship or not in a mapping relationship table, wherein the mapping relationship table comprises the mapping relationship between multiple pieces of operation instruction information and application program operation; if the operation instruction information has the mapping relationship in the mapping relationship table, obtaining a fingerprint pattern input by a user through a fingerprint sensor; verifying whether the obtained fingerprint pattern is matched with at least one preset standard fingerprint pattern or not; and if the obtained fingerprint pattern is matched with at least one preset standard fingerprint pattern, executing the application program operation corresponding to the operation instruction information. The method can effectively reduce the misoperation caused by that the touch screen of the mobile terminal is touched or operated under an unconsciousness situation to cause the touch screen to respond so as to enter an operable state according to the definition and the detection judgment of fingerprint confirmation information, user demands can be more accurately met, a correct recognition rate of a black screen gesture is improved, the operation experience degree of the user is obviously improved, and meanwhile, the cruising ability of a mobile phone is improved.

Description

technical field [0001] The invention relates to the technical field of mobile terminal communication, in particular to a method, device and mobile terminal for preventing misoperation by using fingerprint confirmation. Background technique [0002] With the development and popularization of smart mobile terminals for more than ten years, mobile terminal equipment has become an indispensable tool for people's work and life. In the era when touch screen terminals occupy the mainstream of the market, more and more users feel touch The convenience of touch screen mobile terminals, most of today's touch screen mobile terminals use capacitive touch screens, and capacitive touch screen technology works based on the current induction of the human body. When the user's finger touches the metal layer, due to the electric field of the human body, the user and the surface of the touch screen form a coupling capacitance. For high-frequency currents, the capacitance is a direct conductor,...

Problems solved by technology

[0003] At present, more and more people carry smart mobile terminals with them. During the process of carrying the mobile terminal at any time, the user may touch or operate the touch screen of the mobile terminal unconsciously to make it respond and enter the operable state, which is called Misoperation is not intended by the user. Serious misoperation may cause many problems, such as hanging up the phone by mistake, dialing the phone by mistake, etc., and turning on the camera, flashlight, recording, and camera commonly used applications for black screen gestures. The setting also has the phenomenon of turning on by mistake. For example, the flashlight is turned on by mistake, and the flashlight consumes a lot of power. If the mistake occurs in the daytime, it is not easy to detect, which will seriously affect the battery life of the mobile terminal and the mobile terminal will heat up and bring discomfort to the user. Good experience, reduce user experience
