[0002] With the widespread use of touch screens in electronic devices, users' interactive operations on electronic devices have become increasingly convenient. In order to further improve the user's visual experience and the appearance of electronic devices, full-screen designs have become popular. As the screen-to-body ratio increases, the edges of electronic devices become narrower, which makes it easy to accidentally touch when using electronic devices.

[0003] In order to prevent the impact of accidental touches on the use of the edge, the commonly used method to prevent accidental touches is to add a dead zone in the edge area, and any touch signal generated in the dead zone is invalid, thereby preventing accidental touches.

[0105] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0106] In the specification, unless otherwise clearly stated, the terms "first" and "second" are used only to describe and distinguish constituent elements, and should not be understood as indicating an order. Unless otherwise clearly stated, the terms "connected", "fixed", etc. should be understood as having a broad meaning, including but not limited to directly, indirectly, detachably "connected", "fixed", etc.

[0107] Figure 1 The process of the method for preventing accidental touch according to an exemplary embodiment is shown as follows Figure 1 ,like Figure 1 As shown, the method mainly includes the following steps:

[0108] In step 101, when the electronic device is in a target posture, a grasping operation within a preset area of ​​the touch screen is detected; wherein, in the target posture, the angle between the orientation of the touch screen of the electronic device and the gravity direction of the electronic device is within a preset angle range; and the grasping operation corresponds to at least two grasping areas.

[0109] In this embodiment, the electronic device is a device with a touch screen that is prone to accidental touches during use, such as: mobile phones, tablets, smart watches, smart wearable devices, etc. When the electronic device is in the target posture, that is, the angle between the orientation of the touch screen of the electronic device (that is, the orientation of the display surface of the touch screen used to display the picture) and the gravity direction of the electronic device is within a preset angle range, and the preset angle range is 0-90 degrees. At this time, the user's use state of the electronic device is a lying state. It can be understood that no matter whether the user is in a supine lying state or a side-lying lying state, when using the electronic device, the touch screen of the electronic device is facing the user at a certain angle. Therefore, by judging the angle between the orientation of the touch screen and the gravity direction, it can be determined whether it is a lying state.

[0110] When the electronic device is in the target posture and is grasped, the grasping operation in the preset area of ​​the touch screen is detected. The false touch operation in the preset area will be determined as an invalid touch, and the non-false touch operation in the preset area will be determined as a valid touch. For invalid touch, the processor in the electronic device will not respond to its touch data, and for valid touch, the processor in the electronic device will respond and process its touch data. In the non-preset area, all touch operations will be determined as valid touches. Therefore, by detecting the touch operation in the preset area of ​​the touch screen to determine whether it is a false touch, and suppressing the false touch, the anti-false touch performance of the touch screen can be effectively improved.

[0111] The preset area is generally set at a position on the touch screen where accidental touch operations are prone to occur, such as: the edge positions on both sides of the touch screen, the bottom corner positions of the touch screen, etc. The specific shape, size, and position of the preset area can be adjusted according to the size of the electronic device, the user group, the application scenario, etc.

[0112] In step 102 , when a gripping operation is detected, a target gripping region is determined based on gripping parameters of each gripping region.

[0113] In this embodiment, the grasping operation of the electronic device corresponds to at least two grasping areas, and the target grasping area can be determined based on one or more grasping parameters such as the area of ​​the grasping area, the shape of the grasping area, the grasping duration of the grasping area, and the position of the grasping area. The target grasping area can be understood as the area in the lying state where the possibility of being grasped is the highest and the grasping operation corresponding to the area is the highest possibility of being an accidental touch operation.

[0114] It should be noted that, whether it is a capacitive touch screen, a resistive touch screen, or other types of touch screens, the display module of the electronic device will have multiple sensors arranged in an array. The multiple sensors arranged in an array can be regarded as dividing the touch screen into multiple touch units to detect touch operations at various positions of the touch screen and output touch data. A touch operation of the user's hand will involve multiple touch units, and multiple sensors corresponding to multiple touch units can detect and output touch data. Based on the coordinates of these touch data corresponding to the touch screen, the touch area of ​​this touch operation can be determined. That is, based on the touch data of the grasping operation, the grasping area and the parameters of the grasping area can be determined.

[0115] In step 103, an area to be adjusted is determined from a preset area, and the area of ​​the area to be adjusted is adjusted; wherein the area to be adjusted includes at least a target gripping area; when a gripping operation within the preset area is an erroneous touch operation, no response is given to the touch data of the gripping operation.

[0116] In this embodiment, since the target grasping area is located within the preset area, the area to be adjusted can be determined from within the preset area based on the determined target grasping area. Figure 2 As shown in , the area of ​​the region to be adjusted may be the same as the area of ​​the target grasping area. Figure 3 As shown, the area of ​​the region to be adjusted ( Figure 3 The area of ​​the rectangular area in the middle) may also be larger than the area of ​​the target grasping area ( Figure 3 The area of ​​the ellipse in the figure).

[0117] Of course, there may be only one target grasping area determined based on the grasping parameters of the grasping area, and correspondingly there is only one area to be adjusted; or multiple target grasping areas may be determined, and correspondingly there are multiple areas to be adjusted.

[0118] In this embodiment, the non-response operation to the touch data of the gripping operation may be not reporting the touch data of the gripping operation, or not responding to or executing a touch event corresponding to the touch data of the gripping operation.

[0119] In some embodiments, the method for preventing accidental touches further includes: obtaining acceleration sensor parameters and gravity sensor parameters of the electronic device; inputting the acceleration sensor parameters and gravity sensor parameters into a trained state recognition model to determine the target posture of the electronic device.

[0120] In this embodiment, the acceleration sensor can detect the acceleration and the inclination angle of the electronic device in the process of moving, and the gravity sensor can detect the motion state of the electronic device and the inclination angle relative to the horizontal plane. Therefore, based on the sensing parameters of the acceleration sensor and / or the gravity sensor, it can be determined whether the electronic device is in the target posture. Specifically, the lying state can be determined by inputting the acceleration sensor parameters and the gravity sensor parameters into the trained state recognition model to determine the current user use state of the electronic device. The state recognition model can be any one or more combinations of convolutional neural networks, support vector machines, long short-term memory networks, recursive neural networks, etc.

[0121] In some embodiments, Figure 4 As shown, in step 101, detecting a gripping operation within a preset area of ​​the touch screen includes:

[0122] In step 1011, when there is a touch operation in the preset area, touch data corresponding to the touch operation is acquired.

[0123] In step 1012, a gripping operation is determined based on the touch data and / or the touch area on which the touch operation acts; wherein the preset areas are multiple and are respectively located on two opposite sides of the touch screen.

[0124] In this embodiment, the display module of the electronic device has multiple sensors arranged in an array, and the multiple sensors arranged in an array can be regarded as dividing the touch screen into multiple touch units, and each sensor detects the touch operation of the touch unit corresponding to itself to obtain touch data. The touch area corresponding to the touch operation can be determined based on the coordinates of the touch data corresponding to the touch screen.

[0125] In addition, since the grasping operation in the lying state mostly acts on the edge area of ​​the touch screen and most of them are accidental touch operations, the touch data can be calculated to determine the pressing force and the pressing force distribution trend, and determine whether it is a grasping operation based on the pressing force or the pressing force distribution trend. It can also be determined whether it is a grasping operation based on the position of the touch area, the shape of the touch area, the distribution trend of the touch area, the touch duration of the touch area, etc.

[0126] Since the gripping operation is mostly performed on the edge area of ​​the touch screen, the preset area can be set to two opposite sides of the touch screen, for example, a preset area is set to the left edge area of ​​the touch screen, and a preset area is set to the right edge area of ​​the touch screen. Of course, the shape and area of ​​the left preset area can be the same as or different from the shape and area of ​​the right preset area.

[0127] In some embodiments, step 1012 includes: when there is at least one touch area in each of the preset areas located on the two sides, determining the touch operation corresponding to the at least one touch area as a grasping operation.

[0128] In this embodiment, Figure 5 As shown, a gripping operation will form touch areas within the preset areas (edge ​​areas) on both sides of the touch screen. Therefore, taking the preset areas located in the left area and the right area of ​​the touch screen as an example, if there is at least one touch area in the preset area on the left and there is also at least one touch area in the preset area on the right, then the touch operation within the preset area of ​​the touch screen is determined to be a gripping operation.

[0129] In some embodiments, step 1012 includes: when there are at least two touch areas in the preset area located on any side, determining the distance between the touch areas; and determining the touch operation corresponding to the touch area whose distance is less than the preset distance threshold as a grasping operation.

[0130] In this embodiment, Figure 5 As shown, a gripping operation will form at least two touch areas with a relatively close distance within the preset area (edge ​​area) on either side of the touch screen. Therefore, taking the preset areas being located in the left area and the right area of ​​the touch screen as an example, if there are at least two touch areas in the preset area on the left, and the distance between the two touch areas is less than the preset distance threshold, the touch operation corresponding to the touch area is a gripping operation; or, if there are at least two touch areas in the preset area on the right, and the distance between the two touch areas is less than the preset distance threshold, the touch operation corresponding to the touch area is a gripping operation.

[0131] In some embodiments, step 1012 includes: determining a pressure distribution parameter based on touch data corresponding to the touch operation; wherein the pressure distribution parameter is used to characterize the pressure distribution trend of the touch operation; when the pressure distribution parameter is continuously greater than a preset force distribution threshold within a preset time period, determining that the touch operation is a grasping operation.

[0132] In this embodiment, the pressing force of the touch area formed by the grasping operation in the lying state is not uniform, and mostly acts on the edge area of ​​the touch screen. Therefore, if it is a grasping operation, the pressing center of gravity is biased towards the edge area of ​​the touch screen and the duration is long, that is, the pressing force of the edge area of ​​the touch screen is continuously maintained to be large, and the pressing force of the non-edge area is small. If it is not a grasping operation, the pressing center of gravity is generally in the non-edge area of ​​the touch screen and the duration is short, that is, the pressing force of the non-edge area of ​​the touch screen is large in a short time, and the pressing force of the edge area is small. Therefore, whether the touch operation is a grasping operation can be determined based on whether the pressing force distribution parameter is continuously greater than the preset force distribution threshold within a preset time length.

[0133] Specifically, the pressing force distribution parameter includes: a corner pressing force distribution parameter and / or an edge pressing force distribution parameter;

[0134] If the coordinates corresponding to the maximum value in the sensor touch data are the top corner positions of the touch screen, determining a first sum value between the sensor touch data in a first L-shaped region including the maximum value, and a second sum value between the sensor touch data in a second L-shaped region adjacent to the first L-shaped region, and determining a corner press force distribution parameter based on a ratio between the first sum value and the second sum value; and / or;

[0135] If the coordinates corresponding to the maximum value are non-vertex positions of the touch screen, determine a third sum value between at least one sensor touch data in the direction of the straight line where the maximum value is located; and a fourth sum value between at least one sensor touch data in the direction of a straight line adjacent to the straight line where the maximum value is located, and determine the edge pressure intensity distribution parameter based on the ratio between the third sum value and the fourth sum value.

[0136] In this embodiment, the calculation of the pressure distribution parameters is based on the position of the coordinates corresponding to the maximum value in the sensor touch data on the touch screen, and the specific calculation method of the pressure distribution parameters is determined. It can be understood that there are multiple sensors arranged in an array in the display module of the electronic device. The multiple sensors arranged in an array can be regarded as dividing the touch screen into multiple touch units. Each sensor detects the touch operation of the touch unit corresponding to itself to obtain touch data, so each touch data has corresponding coordinates in the touch screen. The maximum value in the touch data is the position with the maximum pressure, that is, the center of gravity of the touch operation.

[0137] by Figure 6 For example, when the coordinates of the maximum value are the vertex position of the touch screen, it means that the center of gravity of the touch operation is at the vertex position. At this time, the first L-shaped area containing the maximum value (1148) is calculated (such as: Figure 6The sum of the touch data of the middle dot matrix pattern area) is (142+514+962+1148+905+148) to obtain the first sum value, and then the second L-shaped area adjacent to the first L-shaped area is calculated (such as: Figure 7 The sum of the touch data in the middle grid pattern area (64+247+50) is obtained to obtain a second sum value, and the ratio of the first sum value to the second sum value is calculated to determine the corner pressure intensity distribution parameter.

[0138] by Figure 7 For example, when the coordinates of the maximum value are at non-vertex positions of the touch screen, if the touch data are distributed in the column direction, the sum of the touch data in the column straight line direction where the maximum value is located is calculated (eg: Figure 7 The third sum value (422+1139+1111+292) is obtained, and then the sum of the touch data in the straight line direction adjacent to the column straight line direction where the maximum value is located is calculated (such as: Figure 7 Of course, if the touch data is distributed in the row direction, the calculation is based on the row straight line direction.

[0139] In some embodiments, during detection of a gripping operation within a preset area of ​​the touch screen, if the touch operation is determined to be a sliding operation between a non-preset area and a preset area of ​​the touch screen, it is determined that the touch operation is not a gripping operation.

[0140] In this embodiment, when the touch operation is determined to be a sliding operation between a non-preset area and a preset area of ​​the touch screen, that is, when it is detected that the touch operation moves rapidly within a preset time, or the area with touch data on the edge decreases rapidly, or the area with touch data on the edge increases rapidly, etc., it can be determined that the sliding operation may be a full-screen gesture operation rather than a grasping operation.

[0141] In some embodiments, the grasping parameters include: grasping duration and grasping area; step 102 includes: determining a grasping area with a grasping duration greater than a preset duration threshold and a grasping area greater than a preset area threshold as a target grasping area.

[0142] In this embodiment, the gripping duration and gripping area of ​​the gripping area are obtained. The gripping area greater than the preset area threshold and the gripping duration greater than the preset duration threshold are determined as the target gripping area. It can be understood that the gripping area with a long gripping duration and a large gripping area is the area that is most likely to be gripped by the user in a lying state, and the gripping operation corresponding to the area is most likely to be an accidental touch operation.

[0143] In some embodiments, the grasping duration can be determined by the following method: mark each grasping area according to the falling time of the operating body corresponding to each grasping area, and determine the label of each grasping area; determine the lifting time of the operating body corresponding to the grasping area corresponding to each label; based on the falling time and the lifting time, determine the grasping duration.

[0144] In this embodiment, the grasping duration is determined by marking each grasping area, determining the hand drop time and lift time of the grasping area corresponding to each label, and determining the grasping duration based on the drop time and lift time. The grasping area can be marked to determine the label based on the hand drop time of each grasping area, or based on the detection time of the grasping area, or based on the maximum value of the touch data corresponding to the grasping area.

[0145] Taking the determination of the label at the time when the hand is put down as an example, for example: three touch areas are formed on the touch screen at T1, T2, and T3 respectively, the touch area at T1 is marked as 1 (ID=1), the touch area at T2 is marked as 2 (ID=2), and the touch area at T3 is marked as 3 (ID=3).

[0146] Taking the determination of the label at the detection time of the grasping area as an example, for example: at time T1, two touch areas are formed on the touch screen at the same time, and the detection direction of the touch screen grasping area is set from left to right and from top to bottom, then the touch area detected first is marked as 1 (ID=1), and the touch area detected later is marked as 2 (ID=2).

[0147] Taking the size of the maximum touch data value to determine the label as an example, for example: at a certain moment, three touch areas are formed on the touch screen, and the maximum touch data values ​​in these three touch areas are obtained respectively. The three obtained touch data maximum values ​​are compared, and the corresponding touch areas are marked as 1, 2, and 3 in order from large to small.

[0148] In some embodiments, adjusting the area of ​​the region to be adjusted includes: extending the region to be adjusted toward a non-preset area of ​​the touch screen. In addition, when the preset area extends to a preset position in the touch screen, the area of ​​the region to be adjusted stops being adjusted.

[0149] In this embodiment, once the target gripping area that satisfies the gripping duration and gripping area is determined, the area of ​​the area to be adjusted corresponding to the target gripping area is increased, that is, the area to be adjusted can be extended toward the non-preset area. In this way, in the area where the non-preset area extends, each touch operation in the area will be detected, and the detected false touch operation will be suppressed (that is, the touch operation will not be responded to), so as to achieve the prevention of false touch for deep grip in the lying state.

[0150] Of course, extending the area to be adjusted toward the non-preset area, that is, increasing part of the area in the preset area (no response to accidental touch operations, response to non-accidental touch operations) toward the non-preset area (response to all operations), this increase is not unlimited. When it increases to the preset position in the touch screen, the adjustment will stop.

[0151] In one embodiment, adjusting the area of ​​the region to be adjusted includes: determining the area of ​​the target gripping region, the area of ​​the region to be adjusted, and a preset first adjustment parameter. Based on the area of ​​the region to be adjusted, the area of ​​the target gripping region, and the first adjustment parameter, adjusting the area of ​​the region to be adjusted.

[0152] In this embodiment, the area of ​​the area to be adjusted after adjustment (S1) is the area of ​​the area to be adjusted before adjustment (S0) and the area of ​​the target grasping area (S touch ) and the first adjustment parameter (K1). The calculation formula is as follows:

[0153] S1=S0+S touch ×K1

[0154] The first adjustment parameter K1 can be used to adjust the device based on the size of the touch screen of the electronic device, the touch performance of the electronic device, the applicable population of the electronic device, etc.

[0155] In one embodiment, adjusting the area of ​​the area to be adjusted further includes: obtaining a moving area in the non-preset area during a grip operation in the preset area moving to a non-preset area of ​​the touch screen; and adjusting the area of ​​the area to be adjusted based on the moving area and a preset second adjustment parameter.

[0156] In this embodiment, when the area to be adjusted is determined based on the target gripping area, when it is detected that the gripping operation in the preset area moves to the non-preset area of ​​the touch screen, the moving area (S move ) and the second adjustment parameter (K2) are used to adjust the area of ​​the area to be adjusted. Specifically, the area (S1) of the area to be adjusted after adjustment is the area (S0) of the area to be adjusted before adjustment and the moving area (S move ) and the second adjustment parameter (K2) multiplied together, and the calculation formula is as follows:

[0157] S1=S0+S move ×K2

[0158] The second adjustment parameter (K2) may be different from or the same as the first adjustment parameter. In addition, the above adjustment operation may be a new adjustment operation or a secondary adjustment of the previous adjustment result.

[0159] Based on the above embodiments, the anti-mistouch method of the present invention selects a target gripping area (i.e., the area that the user is most likely to touch and the area that is most likely to cause a mistouch in a lying state) based on the gripping parameters of the gripping area, determines the area to be adjusted from the preset area based on the target gripping area, and increases the area to be adjusted toward the non-preset area, thereby achieving anti-mistouch when deeply gripping in a lying state.

[0160] Figure 8 FIG. 1 is a schematic diagram of the entire process of preventing accidental touches of a touch screen in a lying position according to an exemplary embodiment. Figure 8 As shown, the steps include:

[0161] In step 801, a lying posture is identified based on acceleration sensor data and gravity sensor data (A+G data);

[0162] In step 802, a grasping operation is identified based on left-right symmetrical edge touch data;

[0163] If the gripping operation is recognized, step 804 is executed; if the gripping operation is not recognized, step 803 is executed;

[0164] In step 803, it is determined whether a corner pressing force distribution parameter (corner ratio) and an edge pressing force distribution parameter (edge ​​ratio) are continuously greater than a preset force distribution threshold;

[0165] If the gripping operation is recognized, step 804 is executed; if the gripping operation is not recognized, the process ends.

[0166] In step 804, the gripping region number of the gripping operation is marked;

[0167] In step 805, the grasping time and the area of ​​the grasping region are counted;

[0168] In step 806, the grasping operation is judged to be a rapid movement;

[0169] If the grasping operation involves rapid movement, the process ends; if the grasping operation does not involve rapid movement, the process proceeds to step 807;

[0170] In step 807, a target grasping area is determined based on the grasping time and the area of ​​the grasping area, a region to be adjusted is determined based on the target grasping area, and the size of the region to be adjusted is adjusted;

[0171] In step 808, it is determined whether the gripping operation further includes a touch action to a non-preset area;

[0172] If there is a touch action to a non-preset area, execute step 809, if not, return to step 806;

[0173] In step 809, the size of the preset area is adjusted for a second time.
