Preferred embodiment of the invention

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other. Embodiment 1

This embodiment provides a method for preventing false triggering of a touch screen. As shown in FIG. 1, the method includes the following steps:

Step 11: The trigger area corresponding to the program is divided into at least two sub-trigger areas.

After multiple tests, the best way to split the sub-trigger area is to divide the trigger area corresponding to the program icon into four sub-trigger areas. As shown in Figure 2 or Figure 3, each sub-trigger area is evenly distributed in the program icon. Medium, and the area of each sub-trigger area is kept substantially equal, so that the probability of triggering each sub-trigger area is the same. Of course, the manner of dividing the sub-trigger area is not limited to uniform division, and may be determined according to actual usage, and The number of divisions of the trigger area can be modified by the user according to their own usage environment and habits, and can be set to 2, 3 or 6.

The program described here refers to all programs in the terminal, which can be applications in the system or built-in programs of the system.

Step 12: Detect whether the trigger area has a touch operation.

The terminal detects the click operation of the user on the touch screen, saves the coordinates of the point corresponding to the click operation, and determines whether the coordinate is in the trigger area of the program icon. If yes, the trigger area is considered to have a touch operation.

Step 13: When there is a touch operation, calculate the number of sub-trigger regions of the trigger region touched.

The terminal determines whether the coordinate point is in the four sub-trigger regions of the trigger region of the program icon, and if yes, the sub-trigger region of the trigger region is considered to have a touch operation, and the sub-trigger regions touched in the trigger region are calculated. number.

Step 14. When the number of the sub-trigger regions is not less than a preset threshold, the program corresponding to the trigger region is executed.

When calculating that the number of touched sub-trigger regions in the trigger region is greater than or equal to 60% of the total number, triggering a program corresponding to the trigger region, for example, the program icon is logically divided into four sub-regions, The width value is 2.4, and the width is set to 3 after rounding. When 3 or more sub-areas are touched, the application corresponding to the icon is triggered. Of course, this threshold can be set by the user. Depending on the usage environment, the user can set the threshold according to his own usage habits. Set to 40%, 50% or 75%.

This embodiment can be applied to all touch screen models, and can effectively prevent false triggering by software control. The embodiment of the invention has a simple structure, is easy to implement, and effectively improves the user experience.

Embodiment 2

The embodiment provides a system for preventing false triggering of the touch screen. As shown in FIG. 4, the system includes a split module 41, a detection module 42, a calculation module 43, and an operation module 44.

The segmentation module 41 is configured to: divide the trigger region corresponding to the program into at least two sub-trigger regions. Of course, in actual use, the trigger region is evenly divided into four sub-trigger regions for optimal implementation of the number and state of the segmentation, which can be set by the user according to different usage environments and usage preferences.

The detecting module 42 is configured to: detect whether the trigger area has a touch operation.

The terminal detects whether the user has an operation of clicking a program icon on the touch screen.

The calculation module 43 is configured to: when there is a touch operation, calculate the number of sub-trigger regions of the trigger region touched.

Whether the sub-trigger area eight, the sub-trigger area B, the sub-trigger area C, and the sub-trigger area D (shown in FIG. 2) corresponding to the terminal detection program icon are touched, that is, whether the coordinate point of the click operation on the touch screen is determined whether In the sub-trigger area of the trigger area. If so, the number of sub-trigger areas that are touched is calculated. For example, if the sub-trigger area A, the sub-trigger area B, and the sub-trigger area C are touched, the number of touched sub-trigger areas is three.

The running module 44 is configured to: when the number of the sub-trigger regions is not less than a preset threshold, run a program corresponding to the trigger region.

The result of the calculation of the calculation module 43 is determined. When the calculated number of sub-trigger regions touched in the trigger region is greater than or equal to a threshold value (60% of the total number), the threshold value of the embodiment is 3 That is, when the number of touched sub-trigger regions is greater than or equal to three, the application corresponding to the trigger region is executed.

When the number of touched sub-trigger regions is less than three, the touch action is ignored, and the next touch operation is detected in the trigger region corresponding to the application icon. The following is an example of an application scenario of the present invention: In an intelligent or non-intelligent operating system, an application has a corresponding icon on the desktop. In the embodiment of the present invention, the original icon is logically divided into two. Or two or more sub-areas, and four sub-areas are divided into four sub-areas. However, when the user clicks on the icon of the application, the system does not immediately run the application. The system first determines that several sub-areas are clicked, and when the number of sub-regions that are clicked is greater than or equal to the threshold, for example, The threshold is 3, and when the number of sub-regions that the user clicks is 3, the application is run. This can prevent the user from accidentally touching the application icon and causing the application to run. As shown in Fig. 2, due to the user's improper operation, the user may only click on the edge or each small part of the icon, for example. When the user accidentally touches the left half of the icon (the A sub-region and the C sub-region) in FIG. 2, only two sub-regions are clicked (less than the threshold value), which is described in the embodiment of the present invention. This click action will be considered a misoperation, ignoring this click. This can avoid unnecessary triggering caused by user misoperation. When the user operates correctly, the user will click on the center of the icon accurately, that is, can click on 3 or more sub-areas, and the operating system runs the corresponding program, that is, the user is executed correctly. Operation instructions.

Finally, by using the method or system according to the embodiment of the present invention, it is possible to avoid false triggering caused by accidental touch, causing unnecessary loss, and ultimately improving the user experience.

Obviously, those skilled in the art should understand that the modules or steps of the above embodiments of the present invention can be implemented by a general computing device, which can be concentrated on a single computing device or distributed among multiple computing devices. On the network, optionally, they may be implemented by program code executable by the computing device such that they may be stored in the storage device by the computing device and, in some cases, may be different from The steps shown or described are performed sequentially, or they are separately fabricated into individual integrated circuit modules, or a plurality of modules or steps thereof are fabricated into a single integrated circuit module.
