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...

The invention discloses a swipe gesture identification method and system based on capacitive touch keys. The system comprises a touch key circuit module which is used for providing enabling signals ofkey accesses; a key scanning control module which is used for polling and outputting the enabling signals of all key accesses in the touch key circuit module; a key sampling value generation module which is used for carrying out sampling counting on clock signals output by the touch key circuit module; a key threshold generation module which is used for generating thresholds for judging key states; a value comparer which is used for comparing sampling values of the keys with the key thresholds; a key state generation module which is used for carrying out judgment according to a comparison result of the value comparer, thereby obtaining states of the keys; and a gesture identification module which is used for judging an accurate gesture action according to the states of the keys output bythe key state generation module. According to the identification system designed through adoption of a method of polling and scanning various touch keys, the system cost is reduced, the system structure is stable and the gesture identification is accurate and stable.
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 ...
