Method, device and terminal for recognizing finger lifting during touch operation

Abstract

The invention elates to a method and device for recognizing finger uplifting in touch operation and a terminal. The method for recognizing finger uplifting in touch operation comprises the following steps of: when a touch signal is detected in an edge controlled area of the terminal, obtaining a reference quantity under the current holding posture, wherein different holding postures correspond to controlled areas, distances from which to an in-plane sensor of the terminal are different, and correspond to different reference quantities; and comparing the current touch signal with the reference quantity, and recognizing a finger uplifting event according to the comparison result. According to the method, regardless of which holding postures are adopted by the users to touch the edge controlled area, and regardless of whether the touch signals detected on the edge controlled area are big or small, the terminal can determine proper reference quantities on the basis of the practical conditions so as to correctly recognize finger uplifting events, so that the problem that certain operation manners are not sensitive as single signal threshold values are set in correlation techniques is avoided; and the method is suitable for the users with various operation habits, so that the user experience is optimized.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a method, device and terminal for recognizing finger lifting during a touch operation. Background technique [0002] Edge touch technology is a new technology carried on the terminal. Through the edge touch technology, the operable area of ​​the terminal extends from the screen to both sides of the frame, so that users can control the terminal by operating the areas on both sides of the frame. Execute the corresponding function. For example, when taking a photo, tap the left and right borders of the terminal to activate the shutter. [0003] In related technologies, capacitive edge touch is very sensitive to the position and size of the finger because the in-plane touch sensor is used to sense the tiny touch signal detected on the terminal frame, and slight differences in the position and size of the finger may It will cause a large difference in the dete...
