Problems solved by technology

However, because the existing misoperation identification methods are not based on the analysis and judgment based on the most original electric field data, the accuracy of misoperation identification is low, and it is easy to mistakenly reject normal touch operations, affecting the user's normal touch experience.

example 1

[0099] Example 1, such as Figure 5 As shown, the area defined by the black line frame is the touch area, and the touch points in the touch area are arranged in a row parallel to the edge of the touch screen, and the sensing signal strengths generated by each touch point are 177, 244, and 235 respectively. The length of a column can be measured by the number of touch points in the column, the first preset value is preferably 4, and the second preset value is preferably 3.

[0100] When the number of touch points in the column is greater than or equal to 4, the geometric shape judging unit judges that the touch area is long and narrow, and the misoperation identifying unit judges that the touch operation is a misoperation.

[0101] When the number of touch points in this column is less than 3, 2 or 1, the geometric shape judging unit judges that the touch area is not long and narrow, and the misoperation recognition unit judges that the touch operation is a normal operation.

example 2

[0103] Example two, such as Figure 6-Figure 8 As shown, the area defined by the black line frame is the touch area, and the touch points in the touch area are arranged in two columns parallel to the edge of the touch screen. The length of a column can be measured by the number of touch points in the column, the third preset value is preferably 5, and the fourth preset value is preferably 4.

[0104] When the number of touch points in a column is greater than or equal to 5, the geometric shape judging unit judges that the touch area is long and narrow, and the misoperation recognition unit judges that the touch operation is a misoperation.

[0105] When the number of touch points in a column is less than 4, 3, 2 or 1, the geometric shape judgment unit judges that the touch area is not long and narrow, and the misoperation recognition unit judges that the touch operation is a normal operation.

[0116] see Figure 9 , the first embodiment of the method for preventing touch screen edge misoperation according to the present invention is proposed, the method includes the following steps:

[0117] S11. Determine a touch area according to a touch operation on an edge of the touch screen.

[0118] Specifically, the sensing signal strength of each touch point is acquired according to the touch operation on the edge of the touch screen; and the rectangular area defined by the touch point whose sensing signal strength is greater than the first threshold is determined as the touch area.

[0119] S12. Identify the geometric shape of the touch area. When it is long and narrow, execute step S13; when it is not long and narrow, execute step S14.

[0120] S13. Determine that the touch operation is a wrong operation.

[0121] S14. Determine that the touch operation is a normal operation.

[0122] Wherein, in step S12, the recognition method of the geometric shape of the touch are...

Abstract

The invention discloses a device and method for preventing touch screen edge misoperation. The device includes a touch region determining module and a misoperation identification module, wherein the touch region determining module is used for determining a touch region according to the touching operation of a touch screen edge, and the misoperation identification module is used for judging whether the geometric shape of the touch region is in a narrow and long shape or not; when the geometric shape of the touch region is in the narrow and long shape, it is determined that the touching operation is the misoperation; when the geometric shape of the touch region is not in the narrow and long shape, it is determined that the touching operation is normal operation. Through analyzing the characteristic of data of the most original electric field changes, the misoperation is identified, and the misoperation identification accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a device and method for preventing misoperations at edges of the touch screen. Background technique [0002] As the size of the screen of the mobile terminal increases and the frame of the screen becomes narrower, the probability of misoperation when operating the mobile terminal with one hand becomes higher and higher. For example, when a person holds a mobile terminal, the palm may inadvertently touch the edge of the touch screen. At this time, the touch screen will detect the touch and report the touch event to perform the corresponding operation. However, the user does not expect this operation at this time, resulting in Misoperation may affect the user's touch experience. [0003] If such misoperations can be recognized, and the touch operation events generated by the misoperations are rejected, no wrong operation instructions will be executed, preventing misoperation...
