Problems solved by technology

However, the existing gesture recognition method displays the gesture drawn by the user during the gesture drawing process of the user, and the gesture recognition can only be performed after the user draws the gesture, that is, the existing gesture recognition method is relatively simple and cannot meet the needs of the user. And the efficiency of gesture recognition is low

[0024] figure 1 It is an implementation flowchart of the gesture recognition method with inflection point provided in the first embodiment of the present invention. The method can be executed by a gesture recognition device with inflection point, wherein the device can be implemented by software and / or hardware, and can be used as a part of a mobile device built into the mobile device. Such as figure 1 As shown, the implementation process includes:

[0025] Step 11. Identify the gesture drawn by the user, and determine whether the gesture drawn by the user includes a preset inflection point.

[0026] Before the user draws a gesture, a preset gesture is set in the mobile device in advance, and a preset inflection point is determined according to the preset gesture. Wherein, the preset gesture can be manually set by the user, or can be preset in the mobile device. During the process of the gesture drawn by the user, the feature points drawn by the user are acquired, and it i...

Abstract

The embodiment of the invention relates to the technical field of touch recognition, in particular to a method and device for recognizing a gesture with an inflection point. The method includes the steps that the gesture drawn by a user is recognized, and whether the gesture drawn by the user contains the preset inflection point or not is determined; when it is recognized that the gesture drawn by the user contains the preset inflection point, the gesture drawn by the user is displayed; whether the gesture drawn by the user is a preset gesture or not is recognized, and a preset application program corresponding to the preset gesture is started according to the recognition result. By the adoption of the method, when the user draws the gesture, the gesture drawn by the user is recognized, the gesture drawn by the user is selectively displayed according to the recognition result, the gesture recognition efficiency of a mobile device is improved, and the requirements of the user are met.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of touch recognition, and in particular to a gesture recognition method and device with an inflection point. Background technique [0002] Smart mobile terminals, such as smartphones and tablet computers, have become more and more popular in recent years. Touch screens are an important part of smart mobile terminals. Recognizing user gestures on the touch screen to respond to user operations has become a common feature of smart mobile terminals. Features. [0003] At present, many smart phones are capable of recognizing gestures of users, and users can set custom gestures according to their own needs. However, the existing gesture recognition method displays the gesture drawn by the user during the gesture drawing process of the user, and the gesture recognition can only be performed after the user draws the gesture, that is, the existing gesture recognition method is relatively simple...
