Embodiment Construction

[0042] The idea, specific structure and technical effects of the present invention will be clearly and completely described below in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, features and effects of the present invention. Apparently, the described embodiments are only some, not all, embodiments of the present invention, and other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0043] The present invention designs a sliding gesture recognition method based on capacitive touch keys, the flow chart is as follows figure 1 shown. Among them, the method of this embodiment can be used on a single button that can be composed of the button S0 and the button S1, and can also be used on the identification of multiple buttons that form a group of two buttons. The buttons used are capacitive single-touch buttons. The methods include:

[0044] S...

Abstract

The invention discloses a sliding gesture recognition method and system based on a touch button. The system includes a touch button circuit module for providing an enabling signal for a button path; a button scanning control module for polling and outputting all The enable signal of the button path; the button sampling value generation module, used to sample and count the clock signal output by the touch button circuit module; the button threshold generation module, used to generate the threshold value for judging the button state; the numerical comparator, used for The size comparison between the sampling value and the button threshold; the button state generation module, used to judge the state of the button according to the comparison result of the numerical comparator; the gesture recognition module, used to judge the state of the button output by the button state generation module Make correct gestures. The recognition system designed by polling and scanning each touch button not only reduces the cost of the system, but also has a stable system structure and accurate and stable gesture recognition.

Description

technical field [0001] The present invention relates to the technical field of touch keys, in particular to a method and system for recognizing sliding gestures based on capacitive touch keys. Background technique [0002] In the prior art, the method adopted in the touch button gesture recognition judgment closes the other button channel when a button is pressed, and does not enable the other button channel until the currently recognized button is released, and judges whether the other button is on or not. Whether to be pressed in the next time slice. If pressed, the method recognizes a swipe. In this method, if two buttons are pressed at the same time, and a button is released for a period of time first, the method will recognize the process as a swipe gesture operation. However, for the user, it is not a swipe gesture that motivates the device. Therefore, there is a certain false trigger recognition in this scheme. For a mature and usable capacitive touch product, it ...
