Problems solved by technology

[0004] The purpose of the embodiment of the present invention is to provide a touch point recognition method, aiming at solving the problem that the touch screen terminal recognizes all touch points located on the edge area of ​​the touch screen as valid touch points, which will interfere with the recognition results of touch gestures, resulting in the recognized touch points Gestures are different from actual touch gestures, reducing the accuracy of recognized touch gestures and the efficiency of touch screen operations

Embodiment 1

[0085] reference figure 1 , figure 1 It is an implementation flowchart of a touch point recognition method provided by an embodiment of the present invention;

[0086] In step S101, the touch screen terminal determines a touch point invalidation strategy;

[0087] Among them, the touch point invalidation strategy includes at least one of the following strategies:

[0088] The first strategy: when the touch point of the touch gesture in the edge area of ​​the touch screen is the first touch point, and the duration of the touch gesture is greater than or equal to the preset time threshold, recognize the touch of the touch gesture in the edge area of ​​the touch screen The point is an invalid touch point;

[0089] The second strategy: when the touch gesture moves at the touch point in the edge area of ​​the touch screen, and within a preset time threshold, the moving distance of the touch point in the edge area of ​​the touch screen is less than the preset distance threshold, the touch i...

Embodiment 2

[0105] This embodiment mainly describes that when the touch screen terminal determines that the touch point invalidation strategy is specifically any one of the first strategy, the second strategy, the third strategy, and the fourth strategy in the touch screen terminal's determination of the touch point invalidation strategy, the basis The implementation process of the touch points of the touch gesture in the edge area of ​​the touch screen and the touch point invalidation strategy to identify the invalid touch points in the edge area of ​​the touch screen is described in detail as follows:

[0106] In an implementation manner of the embodiment of the present invention:

[0107] When the touch point invalidation strategy is the first strategy, the touch points that are invalid in the edge area of ​​the touch screen are identified according to the touch points of the touch gesture in the edge area of ​​the touch screen and the touch point invalidation strategy, which is specifically...

Embodiment 3

[0160] This embodiment mainly describes that when the touch screen terminal determines that the touch point invalidation strategy is any combination of the first strategy, the second strategy, the third strategy, and the fourth strategy in the touch screen terminal's determination of the touch point invalidation strategy, the According to the touch points of the touch gesture in the edge area of ​​the touch screen and the touch point invalidation strategy, the implementation process of identifying invalid touch points in the edge area of ​​the touch screen is detailed as follows:

[0161] Detect whether the touch point of the touch gesture in the edge area of ​​the touch screen is the first touch point;

[0162] If it is detected that the touch point of the touch gesture in the edge area of ​​the touch screen is the first touch point, it is detected whether the duration of the touch gesture is greater than or equal to the preset time threshold, and the duration of the touch gesture ...

Abstract

The invention belongs to the technical field of touch screens and particularly relates to a touch point recognition method and device. The touch point recognition method comprises the steps that a touch screen terminal determines a touch point invalid strategy; a touch event in a touch screen is obtained; according to the touch event, a touch point in a touch screen margin area of a touch gesture is determined; and according to the touch point in the touch screen margin area of the touch gesture and the touch point invalid strategy, an invalid point in the touch screen margin area of the touch gesture is recognized. Due to the fact that the invalid point in the touch screen margin area of the touch gesture can be recognized, the situation that all touch points on the touch screen margin area of the touch screen terminal are recognized as valid touch points, so that the recognizing results of the touch gesture are interfered is avoided, and the accuracy of touch gesture recognition and the efficiency of touch screen operation are improved.

Description

Technical field [0001] The invention belongs to the technical field of touch screens, and in particular relates to a touch point recognition method and device. Background technique [0002] Touch-screen terminals, with their strong operability and novel interface, have gradually replaced traditional keyboard-type terminals and become the mainstream of the market. More and more users are operating terminals to enjoy the convenience that touch screens bring to life. At the same time, the touch screen terminal can perform related operations on the terminal according to various touch gestures on the touch screen. [0003] However, when the user holds the terminal, during the holding process, the user’s finger will touch the edge area of ​​the touch screen. When the user’s finger touches the edge area of ​​the touch screen, the touch screen terminal will always detect the user’s The touch point touched by the finger on the edge area of ​​the touch screen, and the touch point is recogn...
