The above described objects, features, and advantages of the embodiments of the present invention will become more apparent and understood. Give further details. Referring to FIG. 1, a flowchart of a method for adjusting a button identification area according to an embodiment of the present invention is shown. The electronic device in the embodiment of the invention has a touch screen, and when the user uses the electronic device, all or part of the manipulation of the electronic device can be realized by touching the touch screen button. Wherein, when the user clicks on the touch screen, the touch screen area is formed with the touch screen. Each touch screen button has a certain display area on the screen, including the size and position of the display area, and the display area of each touch screen button is different; each touch screen button corresponds to a certain recognition area, and the identification area of the button is used for Judging whether the user clicks the button according to the position of the touch screen area of the user. When the touch screen position of the user is located in the recognition area of a button, such as in the identification area of the button "send", the user is confirmed to click the "send" button. . The recognition area of each touch screen button may have different positions and the same size. For example, the button recognition area may be a center of the display area of the button, a circle with a certain length as a radius, and a circle corresponding to the identification area of each button. the same. The size of the button recognition area can be set and changed as needed, and is not fixed. In this embodiment, the method for adjusting the button identification area may include: Step 101: Acquire a touch screen area of the user on the touch screen. The electronic device can acquire the contact position of the user on the touch screen, thereby determining the touch screen area of the user on the touch screen. The size of the touch screen area represents the average size of the user's contact area with the touch screen when the user performs a touch operation on the touch screen. The touch screen area formed by different user touches is different in size, such as a thick finger of a man, formed when touched. The touch screen area is larger than the touch screen area formed when the woman touches. The touch screen area formed by the user on the touch screen may be located in the display area of the button on the touch screen, or may be located at other positions on the touch screen. Step 102: Determine whether the size of the touch screen area matches the size of the identification area of the button on the touch screen. After obtaining the touch screen area of the user on the touch screen, obtaining the size of the recognition area of the button currently set in the electronic device, and then determining whether the size of the touch screen area matches the size of the button recognition area, that is, comparing the touch screen area. Whether the size is similar to the size of the button recognition area. Specifically, a difference between the difference or the diameter between the longest diagonal lines of the touch panel area and the button recognition area may be calculated, wherein the diagonal line may refer to the touch screen area (or the button identification) a line connecting any two points that are not adjacent to each other at the boundary of the area; if the absolute value of the difference is greater than or equal to the preset length threshold, the two areas are considered to be unmatched, and if the absolute value of the difference is less than the preset For the length threshold, the two regions are considered to match. There are many ways to determine whether the two regions match, and they are not listed here. If the size of the touch screen area matches the size of the recognition area of the button, it is not necessary to adjust the size of the current button recognition area; if the size of the touch screen area does not match the size of the identification area of the button, the next step is performed. Step 103: Adjust the size of the identification area of the button to match the size of the touch screen area. If the touch screen area is larger than the recognition area of the button, and the difference between the two areas exceeds the threshold, the recognition area of the button may be adjusted to match the size of the button recognition area with the size of the touch screen area. If the recognition area of the button is larger than the touch screen area, and the difference between the two areas exceeds the threshold, the recognition area of the button may be adjusted to be small, so that the button recognition area matches the size of the touch screen area. Of course, in this case, generally not This can cause an erroneous operation, so it is not necessary to adjust the recognition area of the button. The process of the adjustment button identifying the area may be according to the size of the touch screen area according to the ratio of the preset touch screen area size to the size of the button recognition area, and determining the size of the identification area of the button in real time; The size of the spare button recognition area selects a button recognition area that is the closest to the size of the touch screen area as an electronic device. In the embodiment of the present invention, the size of the recognition area of the button on the touch screen is adjusted according to the size of the touch screen area on the touch screen, so that the size of the touch screen area matches the button identification area, thereby reducing the touch screen area of the user. The user's experience is enhanced by the erroneous operation caused by the button recognition error. In another embodiment of the present invention, as shown in FIG. 2, the process of determining whether the size of the touch screen area matches the size of the identification area of the button on the touch screen may include: Step 201: Calculating an area of the touch screen area The difference in the area of the identification area of the button. Step 202: Determine whether an absolute value of the difference is greater than or equal to an area threshold. If the absolute value of the difference between the area of the touch screen area and the area of the button recognition area is greater than or equal to the area threshold, it may be determined that the size of the touch screen area does not match the size of the identification area of the button, and step 203 is performed. If the absolute value of the difference is less than the area threshold, it can be determined that the size of the touch screen area matches the size of the identification area of the button, and there is no need to adjust the button recognition area. The area threshold is a preset value, and the specific value may be determined according to requirements, and is not limited herein. Step 203: Adjust the size of the recognition area of the button so that the absolute value of the area difference between the area of the touch screen area and the identification area of the button is smaller than the area threshold. If the area of the touch screen area is much larger than the area of the identification area of the button, the difference between the two is greater than or equal to the area threshold, which may easily cause the user to operate incorrectly. At this time, the identification area of the button may be enlarged, and the area of the area may be increased, thereby The difference between the area of the touch screen area and the area of the identification area of the button is made smaller than the area threshold so that the two areas can match. If the area of the identification area of the button is much larger than the area of the touch screen area, the difference between the two is greater than or equal to the area threshold. At this time, the identification area of the button can be reduced, and the area of the area can be reduced, so that the area of the identification area of the button can be made. The difference in area of the touch screen area is less than the area threshold so that the two areas can match. In another embodiment of the present invention, the button display area may have a certain relationship with the recognition area of the button. For example, the display area of the button may be expanded with the enlargement of the recognition area of the button, and/or the display area of the button may be The method further includes: adjusting the size of the display area of the button when the size of the touch screen area does not match the size of the identification area of the button. The step of adjusting the display area of the button may be performed simultaneously or sequentially with the step of adjusting the identification area of the button In progress, the order is not limited. If the display area of the electronic device is small, it is not suitable to enlarge the display area of the button, or if the button display area is too large to block other display contents of the electronic device, only the identification area of the button may be enlarged; The button display area is not limited, and the display area of the button can be adjusted at the same time when the recognition area of the button is adjusted, for example, the recognition area of the button and the display area of the button are simultaneously enlarged. In another embodiment of the present invention, after the identification area of the button is adjusted, the size of the identification area of the adjusted button may be further saved, so as to keep the identification area of the adjusted button in the subsequent operation of the user. The size is avoided to repeatedly determine whether the size of the touch panel area of the user matches the size of the recognition area of the button on the touch screen, and the adjustment action of the button recognition area is repeatedly performed. In another embodiment of the present invention, when the electronic device is applied to the multi-user scene, before or after the user obtains the touch screen area on the touch screen, the method may further include: after receiving the determination instruction, performing the foregoing determination The step of matching the size of the touch screen area with the size of the recognition area of the button on the touch screen for use by a plurality of user operations.
