Description

Technical Field

[0001] This disclosure relates to the field of communications, and more particularly to a method, apparatus, electronic device, and storage medium for preventing accidental touches. Background Technology

[0002] With the widespread use of touchscreens in electronic devices, user interaction with these devices has become increasingly convenient. To further enhance the user's visual experience and the aesthetics of electronic devices, full-screen designs have become popular. However, as screen ratios increase and bezels become narrower, accidental touches are more likely to occur when using these devices.

[0003] To prevent accidental touches at the edges from affecting usability, a common method is to add a dead zone to the edge area. Any touch signals generated within the dead zone are invalid, thus preventing accidental touches. However, this method renders normal touch operations in the edge area ineffective, impacting the user experience. Summary of the Invention

[0092] The accidental touch prevention method disclosed herein detects grasping operations within a preset area when the electronic device is determined to be in a target posture based on sensing parameters and is being gripped. In the target posture, there is a preset angle between the extension direction of the touchscreen and the direction of gravity of the electronic device; that is, when the electronic device is in a reclining position, grasping operations within the preset area are detected. A target grasping area is determined based on the grasping parameters corresponding to the grasping area of ​​the grasping operation. An area to be adjusted is then determined from the preset area based on the target grasping area, and its area is adjusted. This disclosure assumes that grasping operations in a reclining position are accidental touches; therefore, by determining the area to be adjusted from the preset area based on the grasping parameters and adjusting the area, the edge touch performance of the touchscreen is improved, enhancing the touch experience for users in a reclining position.

[0105] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0106] In this specification, unless otherwise expressly stated, the terms "first" and "second" are used only to describe and distinguish the constituent elements, and should not be construed as indicating order. Unless otherwise expressly stated, the terms "connection," "fixing," etc., should be understood in a broad sense, including but not limited to "connecting" or "fixing" directly, indirectly, or detachably.

[0107] Figure 1 This is a flowchart illustrating an accidental touch prevention method according to an exemplary embodiment. 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 gripping operation is detected within a preset area of ​​the touchscreen; wherein, in the target posture, the angle between the orientation of the touchscreen of the electronic device and the direction of gravity of the electronic device is within a preset angle range; the gripping operation corresponds to at least two gripping areas.

[0109] In this embodiment, the electronic device is a device with a touchscreen that is prone to accidental touches during use, such as a mobile phone, tablet, smartwatch, smart wearable device, etc. When the electronic device is in a target posture, that is, the angle between the orientation of the touchscreen (i.e., the orientation of the display surface of the touchscreen) and the direction of gravity of the electronic device is within a preset angle range, which is 0-90 degrees, the user's usage state of the electronic device is a lying posture. It can be understood that regardless of whether the user is lying flat or lying on their side, the touchscreen of the electronic device is always facing the user at a certain angle when using the electronic device. Therefore, by judging the angle between the orientation of the touchscreen and the direction of gravity, it can be determined whether the user is in a lying posture.

[0110] When an electronic device is in a target posture and being grasped, the grasping operation within a preset area on the touchscreen is detected. Accidental touches within the preset area are identified as invalid touches, while non-accidental touches are identified as valid touches. For invalid touches, the processor in the electronic device will not respond to the touch data; for valid touches, the processor will respond and process the touch data. Outside the preset area, all touch operations are identified as valid touches. Therefore, by detecting and suppressing touch operations within the preset area of ​​the touchscreen, the accidental touch prevention performance of the touchscreen can be effectively improved.

[0111] Preset areas are typically set in locations on a touchscreen where accidental touches are likely to occur, such as the edges of the touchscreen or the bottom corners. The shape, size, and location of the preset areas can be adjusted according to the size of the electronic device, the user group, and the application scenario.

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

[0113] In this embodiment, the gripping operation of the electronic device corresponds to at least two gripping areas. The target gripping area can be determined based on one or more gripping parameters such as the area of ​​the gripping area, the shape of the gripping area, the gripping duration of the gripping area, and the position of the gripping area. The target gripping area can be understood as the area that is most likely to be gripped in a lying position and the area where the gripping operation is most likely to be a mis-touch operation.

[0114] It's important to note that regardless of whether it's a capacitive, resistive, or other type of touchscreen, the display module of any electronic device contains multiple sensors arranged in an array. This array of sensors can be seen as dividing the touchscreen into multiple touch units, enabling the detection of touch operations at various locations on the touchscreen and the output of touch data. A single touch operation by a user's hand involves multiple touch units, and the multiple sensors corresponding to these touch units can detect and output touch data. Based on the coordinates of this touch data on the touchscreen, the touch area of ​​this operation can be determined. In other words, the gripping area and its parameters can be determined based on the touch data from the gripping operation.

[0115] In step 103, an area to be adjusted is determined from the preset area, and the area of ​​the area to be adjusted is adjusted; wherein, the area to be adjusted includes at least the target gripping area; if the gripping operation performed on the preset area is a mis-touch operation, the touch data of the gripping operation is not responded to.

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

[0117] Of course, there may be only one target grasping region determined based on the grasping parameters of the grasping region, and there may also be only one region to be adjusted; or there may be multiple target grasping regions determined, and there may also be multiple regions to be adjusted.

[0118] In this embodiment, the non-response operation to the touch data of the grasping operation may be to not report the touch data of the grasping operation, or to not respond to or execute the touch event corresponding to the touch data of the grasping operation.

[0119] In some embodiments, the method for preventing accidental touches further includes: acquiring the 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 accelerometer can detect the acceleration and tilt angle (up, down, left, right) during the movement of the electronic device, while the gravity sensor can detect the motion state and tilt angle relative to the horizontal plane. Therefore, based on the sensing parameters of the accelerometer and / or gravity sensor, it can be determined whether the electronic device is in a target posture. Specifically, in a lying posture, the current user state of the electronic device can be determined by inputting the accelerometer and gravity sensor parameters into a trained state recognition model. The state recognition model can be any combination of one or more of the following: convolutional neural network, support vector machine, long short-term memory network, recurrent neural network, etc.

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

[0122] In step 1011, if a touch operation exists within a preset area, the 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 where the touch operation is performed; wherein, the preset area is multiple and located on two opposite sides of the touch screen.

[0124] In this embodiment, the display module of the electronic device contains multiple sensors arranged in an array. These sensors can be seen as dividing the touchscreen into multiple touch units. Each sensor detects the touch operation of its corresponding touch unit, obtaining touch data. Based on the coordinates of the touch data on the touchscreen, the touch area corresponding to the touch operation can be determined.

[0125] Furthermore, since most gripping operations in a lying position occur at the edges of the touchscreen and are mostly accidental touches, touch data can be calculated to determine the pressure applied and its distribution trend. Based on the pressure applied or its distribution trend, it can be determined whether an operation is a gripping action. Alternatively, it can be determined based on the location, shape, distribution trend, and duration of the touch area.

[0126] Since most gripping operations occur at the edges of the touchscreen, preset areas can be set on opposite sides of the touchscreen. For example, a preset area can be set on the left edge of the touchscreen, and a preset area can be set on the right edge. Of course, the shape and area of ​​the left preset area can be the same as or different from those of the right preset area.

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

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

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

[0130] In this embodiment, as Figure 5 As shown, a gripping operation will create at least two closely spaced touch areas within a preset area (edge ​​area) on either side of the touchscreen. Therefore, taking the preset areas located on the left and right sides of the touchscreen as examples, if there are at least two touch areas in the preset area on the left side, and the distance between the two touch areas is less than a preset distance threshold, the touch operation corresponding to that touch area is a gripping operation; or, if there are at least two touch areas in the preset area on the right side, and the distance between the two touch areas is less than a preset distance threshold, the touch operation corresponding to that 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; and determining that the touch operation is a gripping operation when the pressure distribution parameter is continuously greater than a preset force distribution threshold within a preset time period.

[0132] In this embodiment, the pressure applied to the touch area during a gripping operation in a lying position is not uniform, and most of the pressure is concentrated at the edges of the touchscreen. Therefore, in a gripping operation, the center of pressure is biased towards the edges of the touchscreen and lasts for a longer period, meaning the pressure is consistently higher at the edges and lower in the non-edge areas. Conversely, in a non-gripping operation, the center of pressure is generally in the non-edge areas and lasts for a shorter period, meaning the pressure is higher in the non-edge areas and lower at the edges for a short time. Therefore, whether a touch operation is a gripping operation can be determined by whether the pressure distribution parameters consistently exceed a preset force distribution threshold within a preset duration.

[0133] Specifically, the pressure distribution parameters include: corner pressure distribution parameters and / or edge pressure distribution parameters;

[0134] If the coordinates corresponding to the maximum value in the sensor touch data are the top corner position of the touch screen, determine the first sum value among the sensor touch data in the first L-shaped area containing the maximum value, and the second sum value among the sensor touch data in the second L-shaped area adjacent to the first L-shaped area, and determine the corner pressure distribution parameter based on the ratio between the first sum value and the second sum value; and / or;

[0135] If the coordinates corresponding to the maximum value are non-vertical corner positions of the touchscreen, determine the third sum value between at least one sensor touch data in the direction of the line where the maximum value is located; and the fourth sum value between at least one sensor touch data in the direction of the line adjacent to the line where the maximum value is located, and determine the edge pressure 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 parameter is based on the position of the coordinates corresponding to the maximum value in the sensor touch data on the touchscreen, thus determining the specific calculation method for the pressure distribution parameter. It can be understood that electronic devices typically have multiple sensors arranged in an array within their display modules. These arrayed sensors can be seen as dividing the touchscreen into multiple touch units. Each sensor detects the touch operation of its corresponding touch unit, obtaining touch data. Therefore, each touch data point has corresponding coordinates on the touchscreen. The maximum value in the touch data represents the position of maximum pressure, i.e., the center of gravity of the touch operation.

[0137] by Figure 6 For example, when the coordinates of the maximum value are at the top corner of the touchscreen, it means that the center of gravity of the touch operation is at the top corner. At this time, the first L-shaped area containing the maximum value (1148) is calculated (e.g.: Figure 6The sum of touch data for the dot matrix pattern area (142+514+962+1148+905+148) is used to obtain the first sum value. Then, the second L-shaped area adjacent to the first L-shaped area (e.g., ...) is calculated. Figure 7 The sum of touch data within the square grid pattern area (64+247+50) is used to obtain the second sum. The ratio of the first sum to the second sum is then used to determine the corner pressure distribution parameters.

[0138] by Figure 7 For example, when the coordinates of the maximum value are at a non-vertical corner position of the touchscreen, if the touch data is distributed in a column direction, then the sum of the touch data in the straight line direction of the column containing the maximum value is calculated (e.g.: Figure 7 (Midpoint pattern area), obtain the third sum (422+1139+1111+292), then calculate the sum of touch data in the line direction adjacent to the column line direction where the maximum value is located (e.g.: Figure 7 The fourth sum (335+255) is obtained from the square grid pattern area. Of course, if the touch data is distributed in a row direction, the calculation is based on the row straight line direction.

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

[0140] In this embodiment, when it is determined that the touch operation is 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 at the edge decreases rapidly, or the area with touch data at the edge increases rapidly, etc., it can be determined that the sliding operation may be a full-screen gesture operation rather than a gripping operation.

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

[0142] In this embodiment, the gripping duration and gripping area of ​​the gripping region are obtained. The gripping area greater than a preset area threshold and the gripping duration greater than a preset duration threshold are determined as the target gripping region. It is understood that gripping regions with long gripping durations and large gripping areas are most easily gripped by users in a lying position, and the gripping operations corresponding to these regions are most likely to be accidental touches.

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

[0144] In this embodiment, the grip duration is determined by marking each gripping area and determining the hand's drop-down and lift-up times for each marked area. The grip duration is then determined based on these drop-down and lift-up times. The gripping areas can be marked based on the hand's drop-down time, the detection time of the gripping area, or the maximum value of the touch data corresponding to the gripping area.

[0145] Taking the determination of the label at the moment the hand is put down as an example, for instance: if three touch areas are formed on the touch screen in sequence at times T1, T2, and T3, then the touch area at time T1 is labeled as 1 (ID=1), the touch area at time T2 is labeled as 2 (ID=2), and the touch area at time T3 is labeled as 3 (ID=3).

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

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

[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 touchscreen. Furthermore, when the preset area extends to a preset position on the touchscreen, the adjustment of the area to be adjusted is stopped.

[0149] In this embodiment, once a target gripping area that meets the gripping duration and gripping area requirements is determined, the area of ​​the region to be adjusted corresponding to the target gripping area is increased, that is, the region to be adjusted can be extended towards a non-preset area. In this way, in the area extended from the non-preset area, every subsequent touch operation in that area will be detected, and the detected accidental touch operations will be suppressed (i.e., no response to touch operations), so as to achieve the prevention of accidental touches for deep gripping in a lying position.

[0150] Of course, extending the area to be adjusted toward a non-preset area means increasing a portion of the preset area (no response to accidental touches, response to non-accidental touches) toward a non-preset area (response to all operations). This increase is not unlimited; the adjustment will stop when the area reaches a preset position on the touchscreen.

[0151] In one embodiment, adjusting the area of ​​the region to be adjusted includes: determining the area of ​​the target grasping 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 grasping region, and the first adjustment parameter, the area of ​​the region to be adjusted is then adjusted.

[0152] In this embodiment, the area of ​​the region to be adjusted after adjustment (S1) is the sum of the area of ​​the region to be adjusted before adjustment (S0) and the area of ​​the target grasping area (S). touch The product of the first adjustment parameter (K1) and the first adjustment parameter (K2) is summed. The calculation formula is as follows:

[0153] S1 = S0 + S touch ×K1

[0154] The first adjustment parameter K1 can be adjusted automatically based on factors such as the size of the electronic device's touchscreen, the electronic device's touch performance, and the target audience of the electronic device.

[0155] In one embodiment, adjusting the area of ​​the region to be adjusted further includes: during the process of moving from a gripping operation within a preset area to a non-preset area of ​​the touchscreen, obtaining the moving area in the non-preset area; and adjusting the area of ​​the region 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, and a gripping operation within the preset area is detected moving towards a non-preset area of ​​the touchscreen, the adjustment is based on the moving area (S). move The area to be adjusted is determined by the second adjustment parameter (K2). Specifically, the area (S1) of the area to be adjusted after adjustment is the sum of the area (S0) of the area to be adjusted before adjustment and the area moved (S). move The sum of the product of the first parameter (K) and the second adjustment parameter (K2) is calculated using the following formula:

[0157] S1 = S0 + S move ×K2

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

[0159] Based on the above embodiments, the method for preventing accidental touches disclosed herein selects a target gripping area (i.e., the area most likely to be touched and the area most likely to cause accidental touches when the user is lying down) based on the gripping parameters of the gripping area, determines an area to be adjusted from a preset area based on the target gripping area, and increases the area to be adjusted to a non-preset area, thereby achieving the prevention of accidental touches when deeply gripping in a lying down position.

[0160] Figure 8 This is a schematic diagram illustrating the entire process of preventing accidental touches on a touchscreen in a lying position, according to an exemplary embodiment. Figure 8 As shown, the steps include:

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

[0162] In step 802, the grasping operation is recognized based on the left and right symmetrical edge touch data;

[0163] If a grasping operation is detected, proceed to step 804; if a grasping operation is not detected, proceed to step 803.

[0164] In step 803, it is determined whether the corner ratio and edge ratio of the pressure distribution parameters are continuously greater than the preset force distribution threshold.

[0165] If a grasping operation is detected, proceed to step 804; otherwise, the process ends.

[0166] In step 804, the gripping area of ​​the gripping operation is labeled;

[0167] In step 805, the gripping time and area of ​​the gripping region are calculated.

[0168] In step 806, the grasping operation is quickly moved for judgment;

[0169] If the grasping operation involves rapid movement, then the process ends; otherwise, proceed to step 807.

[0170] In step 807, a target gripping area is determined based on the gripping time and the area of ​​the gripping area, an area to be adjusted is determined based on the target gripping area, and the size of the area to be adjusted is adjusted.

[0171] In step 808, the grasping operation is subject to a further touch action towards a non-preset area;

[0172] If there is a touch action to a non-preset area, proceed to step 809; otherwise, return to step 806.

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