[0027] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0028] The following describes the accidental touch prevention method, the accidental touch prevention device, the terminal device and the storage medium according to the embodiments of the present disclosure with reference to the accompanying drawings.

[0029] Figure 1 is a flow chart of a method for preventing accidental touches according to an embodiment of the present disclosure.

[0030] It should be noted that the executor of the anti-accidental touch method of the embodiment of the present disclosure is an anti-accidental touch device, which can be set in a terminal device, and the terminal device can be a device such as a smart phone, tablet, computer, TV, wearable device, etc.

[0031] like Figure 1As shown, the method for preventing accidental touches in the embodiment of the present disclosure includes the following steps:

[0032] S101, in response to detecting a touch operation, obtaining a first number of first touch points and a second number of second touch points generated by the touch screen at least at the first N time points; wherein the first touch point is a touch point on a first touch channel, the second touch point is a touch point on a second touch channel, the first touch channel and the second touch channel are touch channels adjacent to each other in an edge area of ​​the touch screen, and N is a positive integer greater than or equal to 3.

[0033] The terminal device first detects whether the touch screen has been touched. For example, the terminal device can collect pressure information on the surface of the touch screen through a signal acquisition device, and determine whether there is a touch operation based on the pressure information on the surface of the touch screen. For example, when the pressure information is greater than the set pressure value, it is determined that the touch screen has been touched. For another example, the terminal device can use the HTC (Host Touch Computing) reporting scheme to determine whether the touch screen has been touched. The HTC reporting scheme is a method for detecting the position and shape of touch points on the surface of the touch screen. The working principle of the scheme is to set a mutual capacitance original signal on the touch screen. The mutual capacitance original signal is realized by setting a series of electrodes and sensors on the touch screen. When a finger or other object touches the screen, the electric field distribution between the electrode and the sensor will be changed, thereby affecting the reception and transmission of the mutual capacitance original signal. By measuring these changes, the position and shape of the touch point can be determined.

[0034] When the terminal device detects that there is a touch operation on the touch screen, since the touch operation may be an erroneous operation, which usually occurs at the edge of the touch screen, before executing step S101 to obtain the first number of first touch points and the second number of second touch points generated by the touch screen at least at the first N time points, the touch position of the touch operation can be obtained first, and then a determination can be made as to whether the touch position is an edge area of ​​the touch screen. If it is an edge area, the first number of contact points (first touch points) on the first touch channel and the second number of contact points (second touch points) on the second touch channel generated by the touch screen at least at the first N time points are obtained first, and then false touch detection is performed on the touch operation based on the first number and the second number.

[0035] Usually, false touches occur at the edge of the touch screen, and the corners of the edge are more special. Figure 2When the touch operation is at the left edge as shown, the first touch channel is the first column of touch channels from left to right, the second touch channel is the second column of touch channels from left to right, the first number of touch points on the first column of touch channels is obtained as ch1, and the second number of touch points on the second column of touch channels is obtained as ch2; when the touch operation position is at the corner of the edge, for example, the touch operation is as follows Figure 3 When the left edge corner is shown, the first touch channel is the first column touch channel from left to right and the first row touch channel from bottom to top, the second touch channel is the second column touch channel from left to right and the second row touch channel from bottom to top, the first number of touch points on the first column touch channel and the first row touch channel is cor1, and the second number of touch points on the second column touch channel and the second row touch channel is cor2.

[0036] S102: Determine a target value at the same time point according to the first quantity and the second quantity at the same time point.

[0037] When the touch operation position is at a non-corner of the edge area, the target value at the same time point is the ratio of the first quantity ch1 to the second quantity ch2 at the same time point; when the touch operation position is at a corner of the edge area, the target value at the same time point is the ratio of the first quantity cor1 to the second quantity cor2 at the same time point.

[0038] S103: Perform false touch detection on the touch operation according to the target values ​​at least at N time points.

[0039] When the target values ​​of at least N time points are greater than the first set value, the terminal device determines that the touch operation is a false touch operation. At this time, the terminal device may be in a grasping or palm-root false touch, and the touch operation needs to be shielded, that is, the touch points on each touch channel in the edge area need to be suppressed. When the target values ​​of at least N time points are less than or equal to the set target value starting from the target value of the Mth (such as the third) time point, it is impossible to determine whether the touch operation is a false touch operation. At this time, it is necessary to obtain the touch duration of the touch operation, and then perform false touch detection on the touch operation based on the touch duration. Wherein, M is a positive integer less than or equal to N.

[0040] When the touch duration is less than the first set duration (such as 200ms), it is determined that the touch operation ends within the first set duration, that is, the user's finger is lifted up. At this time, the touch operation is determined to be a normal touch operation, and the touch operation is reported normally and the corresponding operation is controlled to be executed. When the touch duration is greater than or equal to the first set duration, the long press recognition state is entered.

[0041] In the long press recognition state, since the finger is already in a stable state, the current finger area (number of touch points) will also enter a stable state. Therefore, based on the finger area, it is possible to determine whether the terminal device is in a grasping or large-area palm coverage. The implementation process is as follows: obtain the third number of third touch points (the third touch point is the touch point on all touch channels of the touch screen) generated by the touch screen at multiple (such as 3) time points after the first set time length, and perform false touch detection on the false touch operation based on multiple third numbers.

[0042] If multiple third numbers are all greater than the set number, the finger area has not changed significantly and is in a stable state. At this time, the terminal device is identified as not grasping or touching the base of the palm, and the touch operation can be determined to be a normal touch operation, and the touch operation is reported normally to control the execution of the corresponding operation; if there is a value less than or equal to the set number among the multiple third numbers, the finger area has changed significantly and is not in a stable state. At this time, the terminal device is identified as grasping or touching the base of the palm, and the touch operation can be determined to be a false touch operation, and the touch points currently reported by each touch channel in the edge area are suppressed.

[0043] In order to improve the accuracy of determining whether a touch operation is a false touch operation, the present disclosure defines the set number as follows based on the difference in finger area size: a peak value is obtained from multiple third numbers, and if the peak value is greater than a first set value (such as 10), the set number is determined to be a second set value (such as 4); if the peak value is less than or equal to the first set value (such as 10), the set number is determined to be a third set value (such as 3); wherein the first set value is greater than the second set value, and the second set value is greater than the third set value.

[0044] Therefore, when a touch operation is detected, the detection of false touches of the terminal device is realized based on the number of touch points on the first touch channel and the number of touch points on the second touch channel generated by the touch screen at least at the first N time points, thereby realizing the detection of false touches of the terminal device, effectively preventing false touches on the edges, and improving the user's touch experience.

[0045] In order to make those skilled in the art understand the present disclosure more clearly, Figure 4 As shown, the method for preventing accidental touches in the embodiment of the present disclosure includes:

[0046] S401, determine whether the target values ​​at the first five time points are all greater than the set target value. If yes, execute step S405; if not, execute step S402.

[0047] S402, determine whether the touch duration is greater than 200ms. If yes, execute step S403; if not, execute step S406.

[0048] S403, entering the long press recognition state.

[0049] S404, determine whether the area of ​​the finger is stable. If yes, execute step S406; if no, repeat step S404 three times, and if the area of ​​the finger is still unstable after repeating three times, execute step S405.

[0050] S405: Suppress the touch points on each touch channel currently in the edge area.

[0051] S406, reporting the touch operation normally and controlling the execution of the corresponding operation.

[0052] The touch position described above is the edge area of ​​the touch screen, and the touch position described below includes the non-edge area and the edge area of ​​the touch screen.

[0053] In the present disclosure, if it is determined that the touch position includes the non-edge area of ​​the touch screen, it is necessary to identify the holding state of the terminal device and obtain the touch angle of the touch operation. Then, based on the identification result and the touch angle, the touch points on each touch channel in the corner of the corresponding edge area are suppressed.

[0054] For example, the holding state of the terminal device can be identified through the gravity sensor and the acceleration sensor, and the touch angle can be determined according to the shape of the touch point. If the recognition result is the left-hand holding state and the touch angle is in the first set angle range (the angles of the first quadrant and the fourth quadrant, 0-90° and 270°-360°), the touch points on each touch channel in the corner of the left edge area are suppressed; if the recognition result is the right-hand holding state, and the touch angle is in the second set angle range (the scheduling of the second quadrant and the third quadrant, 90°-270°), the touch points on each touch channel in the corner of the right edge area are suppressed.

[0055] In addition, after the touch operation in the non-edge area is recognized to be completed, the touch points on each touch channel in the corner of the edge area on the corresponding side are suppressed within a second set time period; wherein the second set time period is less than the first set time period, that is, when the finger is lifted, the corresponding corner is suppressed for 100ms, and after 100ms, the above steps S101-S104 are continued to be executed, that is, the logic of no touch operation in the non-edge area is used to continue to determine whether there is a false touch on the touch screen of the terminal device.

[0056] In order to make those skilled in the art understand the present disclosure more clearly, Figure 5 As shown, the method for preventing accidental touch of the present disclosure further includes:

[0057] S501: Touch operation is performed in a non-edge area.

[0058] S502, determining whether the holding state is left-hand holding or right-hand holding.

[0059] S503: Acquire a touch angle of the touch operation.

[0060] S504: Suppress the touch points at the corresponding corners in combination with the holding state and the touch angle.

[0061] S505, after the finger is lifted, the corresponding corner is suppressed for 100ms.

[0062] S506, executing edge area detection logic after 100ms.

[0063] In summary, according to the anti-false touch method of the embodiment of the present disclosure, when a touch operation is detected, the first number of first touch points and the second number of second touch points generated by the touch screen at least at the first N time points are obtained, the first touch point is a touch point on the first touch channel, the second touch point is a touch point on the second touch channel, the first touch channel and the second touch channel are touch channels adjacent to each other in the edge area of ​​the touch screen, and N is a positive integer greater than or equal to 3, and then according to the first number and the second number at the same time point, the target value at the same time point is determined, and finally, according to the target value at least N time points, false touch detection is performed on the touch operation. Therefore, when the present disclosure detects a touch operation, it realizes the detection of false touches of the terminal device according to the number of touch points on the first touch channel and the number of touch points on the second touch channel generated by the touch screen at least at the first N time points, so that the detection of false touches of the terminal device can be realized, and false touches of the edge can be effectively prevented, and the user's touch experience can be improved.
