Inputting identification method and electronic equipment

Abstract

The invention provides an inputting identification method and electronic equipment. The method is applied to the electronic equipment, and comprises the steps of: sampling contact positions in a contact sliding process, and acquiring multiple sampling points at different contact positions and different times; extracting a plurality of undetermined corner points from the multiple sampling points; acquiring multiple pairs of sampling points corresponding to multiple undetermined corner points, wherein the sampling point pairs and the undetermined corner points are at internals of preset step lengths, and each preset step length is equal to the preset number of sampling points; and according to a positional relation between the multiple pairs of sampling points, determining a corner point from the undetermined corner points. According to the method, calculated amount of the corner point in a contact sliding track can be reduced.

Description

technical field [0001] The present invention relates to the technical field of input, and more specifically relates to an input recognition method and electronic equipment. Background technique [0002] The application of electronic devices with touch screens has become very common. The user touches or performs continuous sliding operations on the touch screen with a finger or a stylus to complete input operations on the electronic device, such as inputting instructions or inputting characters or Chinese characters. [0003] When there is an input operation of a touch point on the touch screen, the electronic device will collect the moving position of the touch point at different time intervals at a fixed time interval, and then obtain characteristic information of a moving track of the touch point. By analyzing the characteristic information of the trajectory of the contact, the current input command of the contact can be determined. In the process of contact movement, so...
