Problems solved by technology

When this method is used on a touch screen, it can solve the problem that the touch screen sometimes regards the interference signal generated by noise interference as an effective operation, but it cannot effectively judge whether the action is double-click or double-click

Embodiment

[0020] Such as figure 1 As shown, the method for judging double-click on a touch screen of the present invention includes the following steps:

[0021] (1) The minimum time difference and minimum coordinate difference are preset in the data processing module, and their values ​​are greater than the default time difference and coordinate difference in the computer system; the minimum time difference can be 100~500ms, and the minimum coordinate difference can be 5~50mm; In order to better implement the present invention, the minimum time difference is preferably 200ms, and the minimum coordinate difference is preferably 12mm.

[0022] (2) The computer system starts scanning and detects touch points on the screen;

[0023] (3) The data receiving module records the coordinates and time of the first touch point, which are recorded as the first coordinates and the first time, and send them to the data processing module and the computer system;

[0024] (4) The data receiving module reco...

Abstract

The invention provides a touch screen double-click judgment method. That the action is double click or two times of single click is judged in a way that the coordinate difference and the time difference between the two times of touch points on the touch screen are calculated and then compared with the preset least coordinate difference and the preset least time difference to judge either double click or two times of click is exerted, and a computer system executes the judgment result. The method improves the double-click success ratio of the touch screen greatly, and does not affect the double-click success ratio when a disjunctive mouse is in operation.

Description

Technical field [0001] The present invention relates to the technical field of touch screens, and in particular to a method for judging double taps on a touch screen. Background technique [0002] In the existing touch screen input device, since the operation is performed by directly touching and clicking the touch screen, when it is double-clicked, compared to the case of direct operation with the mouse, the jitter is larger, which easily exceeds the double-click setting of the computer system. Set range. As a result, it is often difficult to achieve double-click operations on the touch screen, and misoperations often occur. For example, there are two adjacent folders, Folder 1 and Folder 2, and use your finger to perform folder 1 on the touch screen. Double-click quickly, the system often does not perform the operation of double-clicking folder 1 to open folder 1, but will mistakenly judge that folder 1 is clicked, and then folder 2 is clicked. In this way, the success rate of ...
