Problems solved by technology

[0010] In step 3), coordinate system positioning is generally used to program the coordinate positioning range value of each touch button, and the positioning range that the user presses the center point coordinates of the area falls into is highlighted. In this step, each pre-positioned The range of each touch button is relatively small, so it often happens that the user presses an area that does not belong to any positioning range. At this time, the screen does not respond, and the icon menu that the user wants to enter cannot be correctly judged.

Embodiment 1

[0028] The touch screen button area processing method of the present invention, such as figure 1 shown, including the following steps:

[0029] 101) Capture the coordinates of the center point of the area pressed by the user;

[0030] 102) Calculate the distance value between the coordinates of the center point of the user's pressing area and the touch button;

[0031] 103) Select the touch key corresponding to the smallest distance value among the touch keys as the touch key selected by the user.

[0032] The touch screen button area processing method of the present invention adopts the above steps, wherein in step 102, the distance values ​​between the coordinates of the center point of the pressed area and all the touch keys can be used for calculation, and of course it can also be used to determine how many touches the coordinates of the center point of the pressed area are close to. Calculate the distance value of the button, and combine steps 101) and 103) to achieve t...

Embodiment 2

[0037] The touch screen button area processing method of the present invention combines image 3 , including the following steps:

[0038] 201) Capture the coordinates of the center point of the area pressed by the user;

[0039] 202) Calculate the distance value between the coordinates of the central point of the user's pressed area and the touch button;

[0040] 203) Highlighting the touch button corresponding to the smallest distance value;

[0041] In the embodiment of the present invention, the highlighting in step 203 adopts, but is not limited to, the following method: the brightness of the touch button corresponding to the smallest distance value is higher than the brightness of other touch buttons; of course, in addition to the above-mentioned brightness distinction, the smallest The brightness of the touch button corresponding to the distance value is lower than that of other touch buttons. The main purpose of the above-mentioned highlighting is also to allow users...

Abstract

The invention discloses a method and device for processing a key area on a touch screen, relating to the technical field of touch screens. By adopting the method and the device, the menus into which the customers expect to enter can be effectively positioned and the customers can enter into the menus. The method in the embodiment of the invention comprises the following steps: capturing the center point coordinate of a user press area; computing the distance values between the center point coordinate of the user press area and the touch keys; and selecting the touch key corresponding to the minimum distance value from the touch keys as the touch key selected by a user. The device in the embodiment of the invention comprises a capturing unit, a computing unit and a selecting unit, wherein the capturing unit is used for capturing the center point coordinate of the user press area; the computing unit is used for computing the distance values between the center point coordinate of the user press area and the touch keys; and the selecting unit is used for selecting the touch key corresponding to the minimum distance value from the touch keys as the touch key selected by the user. The method and device disclosed by the embodiment of the invention are applied to the technical field of touch screens.

Description

technical field [0001] The present invention relates to the technical field of touch screens, in particular to a method and device for processing key areas of a touch screen. Background technique [0002] Touch screen, also known as touch panel, is an inductive display device that can receive input signals such as contacts. When touching the touch buttons on the screen, the tactile feedback system on the screen can drive various connected devices according to pre-programmed programs. It can be used to replace the mechanical button panel, and to produce vivid audio-visual effects through the liquid crystal display screen; because of its technical convenience, it is widely used in various technical fields such as mobile phones and computers. [0003] The existing method for processing the button area of ​​the touch screen needs to set the positioning range values ​​of all the touch buttons in advance. The specific processing method includes the following steps: [0004] 1) Th...
