The size of the touch screen is getting larger and larger based on factors such as allowing the mobile terminal to display more content on the screen and improving the user's viewing experience.

Due to the large size of the touch screen, the user inevitably generates an erroneous touch operation on the touch screen during use, for example, when the user holds the mobile terminal in the right hand but needs to operate the left half of the touch screen, the right hand finger operates the left half of the touch screen normally. At the same time, the position of the palm of the right hand or the mouth of the tiger may inadvertently touch the touch screen, causing the normal click to become a multi-touch, so that the mobile terminal does not respond to the normal touch operation or generates an error response, which seriously affects the normal use experience of the user. .

detailed description

The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. It should also be noted that, for ease of description, only some, but not all, of the structures related to the present invention are shown in the drawings.

Before discussing the exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as a process or method depicted as a flowchart. Although the flowcharts describe the various steps as a sequential process, many of the steps can be implemented in parallel, concurrently, or concurrently. In addition, the order of the steps can be rearranged. The process may be terminated when its operation is completed, but may also have additional steps not included in the figures. The processing may correspond to methods, functions, procedures, subroutines, subroutines, and the like.

FIG. 1 is a schematic flowchart diagram of a method for controlling a touch screen of a mobile terminal according to an embodiment of the present invention. The method may be implemented by a touch screen control device of a mobile terminal, where the device may be implemented by software and/or hardware, and generally integrated in In the mobile terminal. As shown in Figure 1, the method includes:

Step 101: Detect a multi-touch event that acts on the touch screen of the terminal.

The multi-touch event is an event that simultaneously generates a touch operation at different positions of the touch screen to form a plurality of touch operations on the touch screen. For example, when the user holds the mobile terminal in the right hand and clicks on the touch screen with the right hand finger, the right hand palm also touches the edge of the screen, and then the multi-touch event on the touch screen will be detected. For another example, when the user holds the mobile terminal with both hands and clicks on the touch screen with the right hand finger, while the left hand palm or the finger accidentally touches the left edge area of the screen, then the touch screen will be detected more. Touch event.

The terminal described in this embodiment includes, but is not limited to, a device integrated with a touch screen such as a mobile phone or a tablet computer. The edge anti-missing setting option can be added to the mobile terminal, and the system automatically turns on the edge anti-missing function according to the actual situation or the user can turn on the anti-missing function according to individual needs. For example, the system can detect the current posture of the mobile terminal, and automatically turn on the anti-missing function when the mobile terminal is in the portrait state; when the mobile terminal is in the horizontal screen state, the anti-missing function is not turned on. In this embodiment, it is assumed that the terminal is protected. The false touch function is already on.

Step 102: Acquire a contact area and a pressure value of each touch point corresponding to the multi-touch event.

The contact area of the touch point described in this embodiment includes a contact area value and a contour of the contact surface. For example, the shape of the finger, for example, an elliptical shape of a certain size, can be regarded as the shape of the normal touch point, and the long or irregular shape can be regarded as the shape of the mistouched point.

The pressure value of the touch point may be an average pressure value or a maximum pressure value during the entire touch operation of the touch point, preferably a maximum pressure value.

The touch screens used in the existing mobile terminals include a resistive touch screen, a capacitive touch screen, and a piezoelectric touch screen. When the user touches the touch screen, the touch screen detects touch information and recognizes the user's touch operation. Taking a capacitive touch screen as an example, the touch screen can sense the change of the capacitance. When the user touches the touch screen, the touch screen senses the change of the capacitance, and the touch information of each touch point is recognized. The touch information includes the contact area and the pressure value, and can also The information includes the coordinates of the touched point and the number of touched fingers (the number of touched points), and after the touch information is recognized, the touch information is reported to the upper layer through the input system, so that the terminal determines the false touch according to the touch information of each touch point. point.

Illustratively, the pressure value of the touch operation can be obtained by a pressure sensor integrated on the surface of the mobile terminal. Preferably, the touch screen of the mobile terminal in the embodiment is a pressure sensing screen, and the pressure sensing screen is a new type of mobile terminal touch screen, and the pressure sensing screen is integrated with a pressure sensor, so that the touch screen can not only accurately sense the touch position of the user, but also The magnitude of the force when the user touches can be recognized, that is, the magnitude of the pressure received by the touch screen when being touched by the user can be detected, and the pressure level is recorded as the pressure value corresponding to the touch operation. When the user's hand leaves the touch screen, the pressure value is zero.

Step 103: Determine, according to the contact area and the pressure value of each touch point, an erroneous touch point in each of the touch points to control a touch operation in which the touch screen does not respond to the erroneous touch point.

Generally, the contact area corresponding to the normal touch operation of the user is not too large in a range, and the contact area corresponding to the false touch operation tends to be relatively large, for example, the contact area of the palm at the edge of the touch screen and the contact area of the touch screen are relatively large. If the user accidentally touches the touch screen, the corresponding pressure value tends to be relatively small, and the pressure value corresponding to the normal touch operation is relatively large compared to the false touch operation. Therefore, determining the false touch point in each touch point according to the contact area and the pressure value of the respective touch points in the step may specifically include: if the contact area of the touch point is greater than a preset area threshold and the pressure value is less than the pre- Set the pressure threshold to determine that the touch point is a false touch point. Wherein the preset surface The product threshold and the preset pressure threshold are preset to distinguish whether the touch point is a normal touch point or a false touch point. The preset area threshold may specifically be a maximum contact area of a normal touch point, and the preset pressure threshold may specifically be a minimum pressure value of a normal touch point.

The touch operation for controlling the touch screen not to respond to the erroneous touch point may be implemented by not reporting the touch information of the erroneous touch point, or reporting the touch point information to the upper layer but the upper layer does not process the touch information. achieve.

The method for controlling a touch screen of a mobile terminal provided by the embodiment determines a false touch point of the plurality of touch points corresponding to the multi-touch event according to the contact area and the pressure value of the touch point, so as to control the touch screen not to respond to the touched touch point. The touch operation realizes the anti-missing touch of the touch screen of the mobile terminal. In addition, in this solution, since the false touch point is determined according to the contact area and the pressure value of the touch point, the accuracy of the method of determining the false touch point is high, and the touch screen of the terminal can be more effectively and accurately prevented from being accidentally touched.

FIG. 2 is a schematic flowchart diagram of another method for controlling a touch screen of a mobile terminal according to an embodiment of the present invention. As can be seen from the above embodiments, in general, a touch point having a contact area larger than a preset area threshold among a plurality of touch points of the multi-touch event is determined as an erroneous touch point. When the contact area of multiple touch points is relatively small, it is also possible to make a false touch. Therefore, the embodiment is optimized based on the above embodiment, and “determining the false touch point in each touch point according to the contact area and the pressure value of each touch point” is optimized to: determine the touch points. The contact area is smaller than the set area value, and the touch points are respectively used as the current touch point; the pressure value of the current touch point is compared with a preset pressure threshold; if the pressure value is less than the preset pressure threshold, Then determining the current touch point as a false touch point. The method provided in this embodiment is applicable to a case where the contact area of each touch point in the multi-touch event is less than the set area value.

Correspondingly, as shown in FIG. 2, the method provided in this embodiment includes:

Step 201: Detect a multi-touch event that acts on the touch screen of the terminal.

Step 202: Acquire a contact area and a pressure value of each touch point corresponding to the multi-touch event.

Step 203: Determine that the contact areas of the touch points are all smaller than the set area value, and each of the touch points is used as the current touch point.

The set area value may be the same as the preset area threshold.

Step 204: Determine whether the pressure value of the current touch point is less than a preset pressure threshold. If yes, execute step 205, otherwise perform step 206.

When the contact area of each touch point in the multi-touch event is small (less than the set area value), it is further determined whether the pressure value of the touch point satisfies less than a preset pressure threshold, thereby identifying the multi-touch event. The wrong touch point.

Step 205: Determine the current touch point as an erroneous touch point, and control a touch operation in which the touch screen does not respond to the erroneous touch point.

Step 206: Determine the current touch point as a normal touch point, and control a touch operation of the touch screen in response to the normal touch point.

In the method provided by the embodiment, when it is determined that the contact area of each touch point in the multi-touch event is less than the set area value, the touch point whose pressure value is less than the preset pressure threshold is determined as the wrong touch point, and the touch screen is not controlled. Responding to the touch operation of the erroneous touch point, the prior art adopts a touch point in which a contact area in a multi-touch event is greater than a preset area threshold as an erroneous touch point to prevent mis-touch, resulting in each touch point. When the contact area is smaller than the preset area threshold, it is impossible to determine whether there is a problem of a false touch point. This method makes the terminal's anti-missing function wider applicable, and makes the terminal more effective in preventing false touches.

On the basis of the foregoing embodiment, the comparing the pressure value of the current touch point with the preset pressure threshold includes: determining a preset pressure corresponding to the current touch point according to the touch type of the current touch point a threshold value; comparing a pressure value of the current touch point with the preset pressure threshold. The touch type includes a click, a double click, a slide, or a long press.

It can be understood that the touch pressure corresponding to different types of touch operations is different. Generally, the pressure values of sliding, clicking, double-clicking, and long-pressing touch operations are sequentially increased, and therefore, the error is determined according to the pressure value of the touched point. When a point is touched, the touch type of the touch point can be used as a basis for determining the wrong touch point. The preset pressure threshold corresponding to each touch type may be preset. When the contact area of the current touch point is smaller than the set area value, the preset pressure threshold corresponding to the current touch point is determined according to the touch type of the current touch point, and the current touch is If the pressure value of the point is less than the preset pressure threshold, it is determined that the current touch point is a false touch point.

On the basis of the above embodiment, after determining that the contact areas of the touch points are smaller than the set area value, after the respective touch points are respectively used as the current touch point, the method further includes: if the pressure value of the current touch point When the preset pressure threshold is greater than or equal to, the current touch point is determined as a normal touch point, and the touch operation of the touch screen in response to the normal touch point is controlled.

Based on the above embodiment, determining that the contact area of each touch point is smaller than the set surface After the value is accumulated, the method further includes: determining a touch point having the largest pressure value among the touch points as a normal touch point, and controlling a touch operation of the touch screen in response to the normal touch point.

In the process of operating the touch screen, the contact area corresponding to the accidental touch operation is also small, so that the contact area of the normal touch point and the erroneous touch point corresponding to the multi-touch event acting on the touch screen is smaller than the set area, because more The pressure value of the normal touch point in the touch points is large, and the pressure value of the false touch point is small, and the touch point with the largest pressure value can be determined as the normal touch point.

FIG. 3 is a schematic flowchart diagram of another method for controlling a touch screen of a mobile terminal according to an embodiment of the present invention. The embodiment is optimized based on the foregoing embodiment, and determining “determining the wrong touch point in each touch point according to the contact area and the pressure value of each touch point” is specifically optimized to: determining the touch points of the touch points. The pressure value is less than the set pressure value, and the touch points are respectively used as the current touch point; the contact area of the current touch point is compared with the preset area threshold; if the contact area is greater than the preset area threshold, then The current touch point is determined as a false touch point. The method provided in this embodiment is applicable to a case where the error value is processed when the pressure values of the respective touch points in the multi-touch event are less than the set pressure value.

Correspondingly, as shown in FIG. 3, the method provided in this embodiment includes:

Step 301: Detect a multi-touch event that acts on the touch screen of the terminal.

Step 302: Acquire a contact area and a pressure value of each touch point corresponding to the multi-touch event.

Step 303: Determine that the pressure values of the touch points are all less than the set pressure value, and use the respective touch points as the current touch points.

Step 304: Determine whether the contact area of the current touch point is greater than a preset area threshold. If yes, go to step 305, otherwise go to step 306.

Step 305: Determine the current touch point as an erroneous touch point, and control a touch operation in which the touch screen does not respond to the erroneous touch point.

Step 306: Determine the current touch point as a normal touch point, and control a touch operation of the touch screen in response to the normal touch point.

In the method provided by the embodiment, when it is determined that the pressure values of the touch points in the multi-touch event are less than the set pressure value, the touch point whose contact area is smaller than the preset area threshold is determined as the wrong touch point, and the touch screen is not controlled. Responding to the touch operation of the erroneous touch point, solving the prior art that the touch point in the multi-touch event is less than the preset pressure threshold is used as an erroneous touch point to prevent mis-touching, resulting in When the pressure value of each touch point is less than the preset pressure threshold, it is impossible to determine whether there is a problem of the wrong touch point. This method makes the terminal's anti-missing function wider applicable, and makes the terminal more effective in preventing false touches. .
