The embodiment of the present application discloses a method, a terminal, and a storage medium for identifying abnormal touches, the method including: the touch screen of the terminal receives the first touch operation; the terminal responds to the first touch operation, and collects A frame of capacitive signal of the touch screen; the life cycle is the process from the first touch operation to leaving the touch screen; calculate the characteristic value of the capacitive bright spot corresponding to the first touch operation in a frame of capacitive signal; according to the characteristics of the capacitive bright spot value, and the characteristic value of the capacitive bright spots belonging to the same life cycle as the first touch operation in at least one frame before one frame, determine whether the first touch operation is an abnormal touch operation; if it is determined that the first touch operation is an abnormal touch operation, The response operation triggered for the first touch operation before one frame is recalled, and the first touch operation is not reported in the entire life cycle. In this way, it is helpful to improve the recognition rate of special-shaped touch operations, so as to prevent false touches.
Description
technical field [0001] The present invention relates to the technical field of terminals, and in particular to a method for identifying abnormal touches, a terminal and a storage medium. Background technique [0002] In recent years, the capacitive touch screen has the advantages of high sensitivity and fast response, which makes it widely used, especially in the field of smart phones to bring users a good user experience. At present, smart phones generally use the proximity light sensor to identify obstacles in front of the screen. When the user is answering the call, the proximity light sensor is turned on. When the proximity light sensor recognizes that there is an obstacle within a certain distance threshold, the mobile phone will enter the The screen is off to prevent the screen from being accidentally touched. The proximity light sensor is affected by the recognition angle, and may not be able to recognize obstacles in some scenarios. The mobile phone is still on when...
