Description

Technical Field

[0001] This disclosure relates to the field of terminal equipment technology, and in particular to a method, device, terminal equipment, and storage medium for preventing accidental touches. Background Technology

[0002] With the continuous development of science and technology and network technology, the use of touch screens is becoming more and more widespread.

[0003] Currently, terminal devices such as smartphones commonly use touchscreens with a high screen-to-body ratio. Touchscreens, as a very convenient input / output device, facilitate user interaction with terminal devices, and are therefore widely used in various terminal devices. Curved screens, in particular, can extend the displayed content to the sides of the terminal device, providing users with a richer visual experience. With the popularization of full-screen displays, the bezels of terminal devices are becoming increasingly narrow, and the requirements for the touch experience at the edges of terminal devices are also becoming increasingly demanding. Therefore, preventing accidental touches at the edges has become very important. Summary of the Invention

[0004] This disclosure aims to at least partially address one of the technical problems in the related art.

[0005] To this end, this disclosure proposes a method, device, terminal device, and storage medium for preventing accidental touches. When a touch operation is detected, this disclosure detects accidental touches on the terminal device 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 N time points in the previous period. This enables the detection of accidental touches on the terminal device, effectively prevents accidental touches at the edges, and improves the user's touch experience.

[0006] One embodiment of this disclosure proposes a method for preventing accidental touches, including:

[0007] In response to the detection of a touch operation, a first number of first touch points and a second number of second touch points generated by the touchscreen at least N time points are obtained; 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 adjacent touch channels of the touchscreen in the edge region, and N is a positive integer greater than or equal to 3;

[0008] The target value at the same time point is determined based on the first quantity and the second quantity at the same time point;

[0009] Accidental touch detection is performed on the touch operation based on target values ​​at at least N time points.

[0010] Another embodiment of this disclosure provides a device for preventing accidental touches, including:

[0011] The acquisition module is used to acquire, in response to the detection of a touch operation, a first number of first touch points and a second number of second touch points generated by the touch screen at least 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 adjacent touch channels of the touch screen in the edge region, and N is a positive integer greater than or equal to 3.

[0012] The determining module is used to determine the target value at the same time point based on the first quantity and the second quantity at the same time point;

[0013] The detection module is used to perform accidental touch detection on the touch operation based on target values ​​at at least N time points.

[0014] Another embodiment of this disclosure proposes a terminal device, including a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, it implements the anti-accidental touch method as described in the foregoing aspect.

[0015] Another embodiment of this disclosure provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the anti-accidental touch method as described in the foregoing aspect.

[0016] Another embodiment of this disclosure provides a computer program product having a computer program stored thereon, which, when executed by a processor, implements the anti-accidental touch method as described in the foregoing aspect.

[0017] The present disclosure discloses an anti-mistouch method, anti-mistouch device, terminal device, and storage medium. Upon detecting a touch operation, it acquires a first number and a second number of first touch points and second touch points generated by the touchscreen at least N time points. The first touch point is a touch point on a first touch channel, and the second touch point is a touch point on a second touch channel. The first and second touch channels are adjacent touch channels of the touchscreen in the edge region, and N is a positive integer greater than or equal to 3. Then, based on the first and second numbers at the same time point, a target value is determined for the same time point. Finally, based on the target values ​​at least N time points, mis-touch detection is performed on the touch operation. Therefore, when a touch operation is detected, the present disclosure achieves mis-touch detection of the terminal device by acquiring the number of touch points on the first touch channel and the second touch channel generated by the touchscreen at least N time points, thereby effectively preventing edge mis-touches and improving the user's touch experience.

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

[0028] The following description, with reference to the accompanying drawings, outlines embodiments of the methods, devices, terminal equipment, and storage media for preventing accidental touches.

[0029] Figure 1 This is a flowchart of an anti-accidental touch method according to an embodiment of the present disclosure.

[0030] It should be noted that the subject of the anti-accidental touch method in this embodiment is an anti-accidental touch device, which can be installed in a terminal device, such as a smartphone, tablet, computer, television, wearable device, etc.

[0031] like Figure 1As shown, the method for preventing accidental touches according to an embodiment of this disclosure includes the following steps:

[0032] S101, in response to detecting a touch operation, obtain a first number of first touch points and a second number of second touch points generated by the touch screen at least N time points; wherein, 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 region of the touch screen, and N is a positive integer greater than or equal to 3.

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

[0034] When a terminal device detects a touch operation on the touchscreen, since the touch operation may be a erroneous operation, and erroneous operations usually occur at the edge of the touchscreen, before executing step S101 to obtain the first number of the first touch points and the second number of the second touch points generated by the touchscreen at least in the previous N time points, it can first obtain the touch position of the touch operation, and then determine whether the touch position is an edge area of ​​the touchscreen. If it is an edge area, then first obtain the first number of the first touch points (first touch points) on the first touch channel and the second number of the second touch points (second touch points) generated by the touchscreen at least in the previous N time points, and then perform erroneous touch detection on the touch operation based on the first number and the second number.

[0035] Accidental touches typically occur at the edges of a touchscreen, with the corners being a particularly unique area. Specifically, when the touch operation occurs outside a corner of the edge, for example, when the touch operation is performed at a location such as... Figure 2When the touch operation is at the left edge, the first touch channel is the first column of touch channels from left to right, and 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 ch1, and the second number of touch points on the second column of touch channels is ch2. When the touch operation is at the corner of the edge, for example, when the touch operation is at a corner of the edge... Figure 3 When the left edge corner is shown, the first touch channel is the first column of touch channels from left to right and the first row of touch channels from bottom to top, the second touch channel is the second column of touch channels from left to right and the second row of touch channels from bottom to top, the first number of touch points on the first column of touch channels and the first row of touch channels is cor1, and the second number of touch points on the second column of touch channels and the second row of touch channels is cor2.

[0036] S102, determine the target value at the same time point based on the first and second quantities at the same time point.

[0037] When the touch operation is performed at a non-corner location 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 is performed at a corner location 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, based on target values ​​at at least N time points, performs accidental touch detection on touch operations.

[0039] If the target value at at least N time points is greater than a first preset value, the touch operation is determined to be a false touch. In this case, the terminal device may be gripping or using the palm of the hand for a false touch, requiring the touch operation to be blocked. This means suppressing touch points on each touch channel in the edge region. However, if the target value at at least N time points starts to be less than or equal to the preset target value from the Mth time point (e.g., the 3rd time point), it is impossible to determine whether the touch operation is a false touch. In this case, the touch duration needs to be obtained, and false touch detection is performed based on the touch duration. Here, M is a positive integer less than or equal to N.

[0040] If the touch duration is less than the first set duration (e.g., 200ms), the touch operation is determined to end within the first set duration, i.e., the user's finger is lifted. 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. If 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 area of ​​the finger (the number of touch points) will also enter a stable state. Therefore, based on the area of ​​the finger, it can be determined whether the terminal device is being gripped or covered by a large area of ​​the palm. The process is as follows: after the first set time period, the third number of third touch points (the third touch points are the touch points on all touch channels of the touch screen) generated by the touch screen at multiple (e.g., 3) time points is obtained, and based on the multiple third numbers, accidental touch detection is performed on accidental touch operations.

[0042] If multiple third quantities are all greater than the set quantity, the finger area does not change significantly and remains stable. In this case, if the terminal device is not gripping or touching with the palm heel, the touch operation can be determined to be a normal touch operation, and the touch operation can be reported normally to control the execution of the corresponding operation. If there is a value less than or equal to the set quantity among the multiple third quantities, the finger area changes significantly and is not in a stable state. In this case, if the terminal device is gripping or touching with the palm heel, the touch operation can be determined to be a false touch operation, and the touch points reported by each touch channel in the current edge area can be suppressed.

[0043] To improve the accuracy of determining whether a touch operation is a mistaken touch operation, this disclosure limits the set quantity based on the difference in finger area size as follows: the peak value is obtained from multiple third quantities, and if the peak value is greater than a first set value (e.g., 10), the set quantity is determined to be a second set value (e.g., 4); if the peak value is less than or equal to the first set value (e.g., 10), the set quantity is determined to be a third set value (e.g., 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 accidental touches on the terminal device is achieved 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 N time points in the previous period. This enables the detection of accidental touches on the terminal device, effectively prevents accidental touches at the edges, and improves the user's touch experience.

[0045] To enable those skilled in the art to better understand this disclosure, such as Figure 4 As shown, the method for preventing accidental touches according to an embodiment of this disclosure includes:

[0046] S401, determine whether the target values ​​at the previous 5 time points are all greater than the set target value. If yes, proceed to step S405; if no, proceed to step S402.

[0047] S402, determine if the touch duration is greater than 200ms. If yes, proceed to step S403; if no, proceed to step S406.

[0048] S403, enter long press recognition mode.

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

[0050] S405, suppresses touch points on each touch channel in the current edge area.

[0051] S406 reports the touch operation as normal and controls the execution of the corresponding operation.

[0052] The touch locations described above refer to the edge areas of the touchscreen. The touch locations described below include both the non-edge areas and the edge areas of the touchscreen.

[0053] In this disclosure, if the touch position is determined to include 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 grip state of the terminal device can be identified by gravity sensors and acceleration sensors, and the touch angle can be determined according to the shape of the touch point. If the identification result is a left-hand grip state and the touch angle is within the first set angle range (angles in the first and fourth quadrants, 0-90° and 270°-360°), the touch points on each touch channel in the corner of the left edge area are suppressed. If the identification result is a right-hand grip state and the touch angle is within the second set angle range (angles in the second and third quadrants, 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 detected, the touch points on each touch channel in the corner of the corresponding edge area are suppressed for a second set time. The second set time is less than the first set time. That is, when the finger is lifted, the suppression of the corresponding corner is maintained for 100ms. After 100ms, the above steps S101-S104 are continued. That is, the logic of no touch operation in the non-edge area continues to determine whether there is a mis-touch on the touch screen of the terminal device.

[0056] To enable those skilled in the art to better understand this disclosure, such as Figure 5 As shown, the method for preventing accidental touches disclosed herein also includes:

[0057] S501, touch operation is performed in non-edge areas.

[0058] S502 determines whether the grip is held with the left hand or the right hand.

[0059] S503, obtains the touch angle of the touch operation.

[0060] S504, by combining the grip state and touch angle, suppresses touch points in the corresponding corners.

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

[0062] S506 executes edge region detection logic after 100ms.

[0063] In summary, the anti-mistouch method according to the embodiments of this disclosure, upon detecting a touch operation, acquires a first number of first touch points and a second number of second touch points generated by the touchscreen at least N time points. The first touch point is a touch point on a first touch channel, and the second touch point is a touch point on a second touch channel. The first and second touch channels are adjacent touch channels of the touchscreen in the edge region, and N is a positive integer greater than or equal to 3. Then, based on the first and second numbers at the same time point, a target value is determined at the same time point. Finally, based on the target values ​​at least N time points, mis-touch detection is performed on the touch operation. Therefore, this disclosure, upon detecting a touch operation, achieves mis-touch detection of the terminal device by acquiring the number of touch points on the first touch channel and the second touch channel generated by the touchscreen at least N time points, thereby effectively preventing edge mis-touches and improving the user's touch experience.

[0064] Figure 6 This is a block diagram of an anti-accidental touch device according to an embodiment of the present disclosure.

[0065] like Figure 6 As shown, the anti-accidental touch device 600 of this embodiment includes:

[0068] The detection module 630 is used to detect accidental touches based on target values ​​at at least N time points.

[0078] In response to a touch duration greater than or equal to a first set duration, the third number of third touch points generated by the touchscreen at multiple time points after the first set duration is obtained, and the accidental touch operation is detected based on the multiple third numbers; wherein, the third touch point is a touch point on all touch channels of the touchscreen.

[0079] In one embodiment of this disclosure, when the detection module 630 is used to perform accidental touch detection based on a plurality of third quantities, it includes:

[0080] If multiple third quantities are greater than the set quantity, and the touch operation is determined to be a normal touch operation, the touch operation will be reported normally and the corresponding operation will be executed.

[0081] If a value less than or equal to a set number exists among multiple third quantities, and the touch operation is determined to be a false touch, then the touch points in each touch channel in the current edge region are suppressed.

[0082] In one embodiment of this disclosure, before the detection module 630 performs accidental touch detection based on a plurality of third quantities, it is further configured to:

[0083] Obtain the peak value from multiple third quantities;

[0084] In response to a peak value exceeding a first set value, the set quantity is determined to be a second set value;

[0085] In response to a peak value being less than or equal to a first set value, the set quantity is determined to be a third set value;

[0086] Among them, the first setting value is greater than the second setting value, and the second setting value is greater than the third setting value.

[0087] In one embodiment of this disclosure, the apparatus further includes:

[0088] The first control module is used to obtain the touch position of the touch operation and determine that the touch position is the edge area of ​​the touch screen.

[0089] In one embodiment of this disclosure, the apparatus further includes:

[0090] The second control module is used to determine the touch position, including the non-edge area of ​​the touch screen, 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, it performs suppression processing on the touch points on each touch channel in the corner of the corresponding edge area.

[0091] In one embodiment of this disclosure, when the second control module performs suppression processing on touch points on each touch channel in a corresponding corner area based on the recognition result and the touch angle, it includes:

[0092] In response to the recognition result that the hand is holding the object with its left hand and the touch angle is within the first set angle range, the touch points on each touch channel in the corner of the left edge area are suppressed.

[0097] It should be noted that the foregoing explanation of the anti-accidental touch method embodiment also applies to the anti-accidental touch device of this embodiment, and will not be repeated here.

[0098] According to the embodiments of the present disclosure, the anti-mistouch device acquires, by means of an acquisition module, a first number of first touch points and a second number of second touch points generated by the touchscreen at least N time points when a touch operation is detected.

The first touch channel and the second touch channel are adjacent touch channels of the touchscreen in the edge region, and N is a positive integer greater than or equal to 3. A determination module determines a target value at the same time point based on the first and second numbers at the same time point. A detection module performs mis-touch detection on the touch operation based on the target value at least N time points. Therefore, when a touch operation is detected, the device judges mis-touches on the terminal device based on the number of voltage values ​​collected at the touch points on the first touch channel and the number of voltage values ​​collected at the touch points on the second touch channel in the voltage matrix generated by the touchscreen at least N time points. This effectively prevents edge mis-touches and improves the user's touch experience.
