Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of communication, and particularly relates to a method and device for preventing mistaken touch, an electronic device and a storage medium. BACKGROUND

[0002] With the wide application of touch screens in electronic devices, the interaction operation of users on the electronic devices becomes more and more convenient. In order to further improve the visual experience of users and the value of the electronic devices, the design of full screen is popularized, and with the increasing screen ratio, the edge of the electronic device is getting narrower, which leads to mistaken touch when using the electronic device.

[0003] In order to prevent the influence of edge mistaken touch on use, the commonly used method for preventing mistaken touch is to increase a dead zone in the edge area, and any touch signal generated in the dead zone is invalid, so as to prevent mistaken touch.

[0109] The example embodiments will be described in detail below with reference to the attached drawings. In the following description, the same numbers are used to designate the same elements, unless otherwise indicated. The embodiments described in the example embodiments below do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure, as detailed in the appended claims.

[0110] In the specification, unless explicitly stated otherwise, the terms "first" and "second" are used only to describe in order to distinguish the constituent elements, and should not be construed as representing the order. Unless explicitly stated otherwise, the terms "connection", "fixing", and the like should be construed in a broad sense, including but not limited to "connection", "fixing", and the like directly, indirectly, detachably, and the like.

[0111] Figure 1 is a schematic diagram of a false touch prevention method according to an example embodiment Figure One , as shown in the figure, the method mainly includes the following steps: Figure 1

[0112] ​In step 101, in response to a touch input of an input area displayed in the touch screen, a preset area of the touch screen is adjusted; wherein the input area is used for text response to the received touch input, and the input area at least partially overlaps the preset area.

[0113] In this embodiment, the electronic device is a device with a touch screen and prone to false touch during use, such as a mobile phone, a tablet, a smart watch, a smart wearable device, etc. For example, the input area in the touch screen can be a virtual keyboard area or a handwriting input area, etc. which can respond to the input information of the user in text. The preset area in the touch screen is an area previously defined in the touch screen, and the electronic device will detect the touch operation in this area to determine whether the touch operation is a false touch operation. For the false touch operation in the preset area, the processor in the electronic device does not respond to the false touch operation (i.e. does not report the touch data of the false touch operation or does not execute the touch event corresponding to the false touch operation). For the non-false touch operation in the preset area, the processor in the electronic device will respond to the non-false touch operation.

[0114] Corresponding to the preset area, all touch operations in the non-preset area of the touch screen are directly responded by the electronic device without detection.

[0115] Therefore, the preset area is generally set at a position in the touch screen where false touch operation is prone to occur, such as the edge position of the touch screen, the corner position at the bottom of the touch screen, etc. The shape, size and position of the preset area can be adjusted and set according to the size of the electronic device, the user group, the application scenario, etc.

[0116] Since the input area can be a virtual keyboard area or a handwriting input area, etc. which can respond to the input information of the user in text, and the preset area is generally set at a position in the touch screen where false touch operation is prone to occur, therefore, the input area and the preset area will have some overlapping areas, and then based on the virtual keyboard input or handwriting input in the preset area, the preset area can be adjusted when the typing function of the electronic device is turned on (such as virtual keyboard typing input in a game interface, handwriting input in a chat interface, typing when watching a video and sending a barrage, etc.).

[0117] Specifically, the embodiment can determine the area prone to false touch and the typing state prone to false touch during typing based on the input state of the touch input, the position of the touch area of the touch input, the touch duration of the touch input, the area of the touch area of the touch input, etc. and adjust the size, shape, position, etc. of the preset area based on this.

[0118] In step 102, in the case that the first touch operation is detected in the input area and the first touch operation acts on the adjusted preset area, a false touch detection strategy corresponding to the touch input is used to perform false touch detection on the first touch operation, and a false touch detection result is obtained.

[0119] In this embodiment, the false touch detection on the first touch operation is actually false touch detection on the typing input operation acting on the preset area in the typing input process, so as to prevent false touch input in the edge area in the typing process. In the false touch detection, different touch inputs can correspond to different false touch detection strategies. Specifically, the corresponding false touch detection strategy can be determined based on the manner of the touch input (virtual keyboard input, handwriting input), the input state of the touch input (single-hand input, double-hand input), the size of the display area receiving the touch input, the touch duration of the touch input, the area of the touch region of the touch input, etc. For example, the false touch detection strategy corresponding to the virtual keyboard (9-key keyboard, 26-key keyboard) input is different from the false touch detection strategy corresponding to the handwriting input, the false touch detection strategy corresponding to the single-hand input is different from the false touch detection strategy corresponding to the double-hand input, the false touch detection strategy of the touch region located in the middle position of the preset area is different from the false touch detection strategy of the touch region located in the edge or corner position, and so on.

[0120] In step 103, when the false touch detection result meets the preset false touch judgment condition, the first touch operation is not responded.

[0121] In this embodiment, after the preset area is adjusted and the first touch operation is detected acting on the adjusted preset area, false touch detection is performed on the first touch operation, and the false touch detection result is obtained to determine whether the first touch operation is a valid operation (normal touch operation) or an invalid operation (false touch operation). The invalid operation is not responded, and the valid operation is responded. For example, in this embodiment, the non-response operation of the first touch operation can be that the touch data of the first touch operation is not reported, or the first touch operation corresponding touch event is not responded or executed.

[0122] When the first touch operation acts on the touch screen, since the touch screen is divided into a preset area and a non-preset area, there are three cases. The first case is that the first touch operation acts on the preset area and the non-preset area; the second case is that the first touch operation only acts on the preset area; and the third case is that the first touch operation only acts on the non-preset area.

[0123] The anti-mistouch method of the present disclosure can detect mistouch for touch operations in the preset area and determine whether to respond, and any touch operation in the non-pre-set area is considered as a normal touch operation and a touch response is performed. Therefore, the present embodiment can use a mistouch detection strategy corresponding to the touch input to detect mistouch for touch operations in the preset area in the first and second cases. In this way, the calculation amount of touch operations can be reduced, and mistouch operations can be effectively and accurately identified when typing, improving the typing touch performance of the touch screen and improving the user typing experience.

[0124] In some embodiments, the anti-mistouch method further comprises: obtaining touch data corresponding to the touch input, and determining the input state of the touch input based on the touch data; and / or obtaining acceleration sensor parameters and gravity sensor parameters of the electronic device, and inputting the acceleration sensor parameters and the gravity sensor parameters into the trained state recognition model to obtain the input state of the touch input.

[0125] In the present embodiment, the detection method of the input state of the touch input is divided into two types, and one or both can be used according to the application scenario of the anti-mistouch method, the electronic device applied, the user group faced by the electronic device, the requirements for the detection result (such as accuracy, reliability, speed), and other factors.

[0126] When detecting the input state according to the touch data of the touch input, the input state can be determined according to the position of the touch area corresponding to the touch data, the number of touch areas, the shape of the touch area, the tilt direction of the touch area, and other parameters.

[0127] It can be understood that when it is a single-hand input state (left hand or right hand), the touch area is mostly located on the left or right side of the touch screen, the number of touch areas corresponding to a touch operation is mostly one, the shape of the touch area is mostly similar to the shape of the thumb, and the tilt direction of the electronic device is mostly tilted to one side when typing with the left hand or the right hand. When it is a double-hand input state, the touch area mostly exists on the left and right sides of the touch screen at the same time, the number of touch areas corresponding to a touch operation can be multiple, the shape of the touch area includes the shape of other fingers in addition to the shape of the thumb, and the tilt direction of the electronic device generally exists in tilting to the left and tilting to the right at the same time, or keeping balance.

[0128] In the input state detection of the touch input based on the acceleration sensor and the gravity sensor, the parameters of the two sensors are obtained, and the input state can be obtained by inputting the parameters of the two sensors into the trained state recognition model. The tilt angle of the electronic device is different when typing with one hand and typing with two hands, and the acceleration sensor can detect the tilt angle of the electronic device up, down, left and right, and the gravity sensor can detect the motion state of the electronic device and the tilt angle relative to the horizontal plane. Therefore, the input state can be accurately measured based on the parameters of the two sensors. The state recognition model can be any one or a combination of more than one of a convolutional neural network, a support vector machine, a long short-term memory network, and a recurrent neural network.

[0129] Further, determining the input state based on the touch data includes: determining a touch area corresponding to the touch input based on the touch data corresponding to the touch input; performing ellipse fitting on the touch area to determine an ellipse area and ellipse parameters corresponding to the ellipse area; and determining the input state based on the ellipse parameters; wherein the ellipse parameters include the number of the ellipse areas.

[0130] In this embodiment, whether it is a capacitive touch screen, a resistive touch screen, or other types of touch screens, there will be a plurality of sensors arranged in an array in the display module of the electronic device. The plurality of sensors arranged in an array can be regarded as dividing the touch screen into a plurality of touch units to detect touch operations at each position of the touch screen and output touch data.

[0131] A touch operation of a user's hand involves a plurality of touch units, and a plurality of sensors corresponding to the plurality of touch units can detect and output touch data. Based on the coordinates of the touch data on the touch screen, the touch area of the touch operation can be determined. Since the shape of the finger is similar to an ellipse, the touch area is fitted with an ellipse to determine an ellipse area and ellipse parameters. The ellipse parameters can include the number of the ellipse areas, the tilt direction of the ellipse area, the area of the ellipse area, and the like. Based on the ellipse parameters, the input state of the touch input (single-hand input state, double-hand input state) can be determined. Further, based on the ellipse parameters, it can be determined whether to type with the left hand or the right hand, or even based on the ellipse parameters, the finger corresponding to the touch operation can be determined. When the thumb is touched, the area of the touch area is relatively large, and when the other fingers are touched, the area of the touch area is relatively small. Based on the finger corresponding to the touch operation, the size of the preset area can be adjusted to achieve accurate detection and further improve the accuracy of the false touch detection.

[0132] Further, based on the ellipse parameters, the input state of the touch input is determined, including: in the case that the number of the ellipse areas is greater than one, determining that the input state of the touch input is a double-hand input state; and in the case that the number of the ellipse areas is equal to one, determining that the input state of the touch input is a single-hand input state.

[0133] Specifically, in order to reduce the amount of calculation and improve the detection efficiency, it can be determined whether single-hand typing or double-hand typing is based on the number of elliptical regions.

[0134] In an embodiment, step 101 comprises: adjusting the preset region to the edge region of one side where the touch input is performed, when the input state of the touch input is a single-hand input state; adjusting the preset region to the edge region of both sides where the touch input is performed, when the input state of the touch input is a double-hand input state; wherein the size of the preset region in the single-hand input state is greater than the size of each preset region in the double-hand input state.

[0135] In the embodiment, the possibility and region of the touch input in different input states to generate a false touch are different. In the single-hand input state (left-hand input or right-hand input), the preset region is adjusted to the left edge region or the right edge region of the touch screen. In the double-hand input state, the preset region is adjusted to the left edge region and the right edge region. For example, when the user performs double-hand typing in a game interface, it is a double-hand input state, and a false touch is not likely to occur at this time. Therefore, the preset region can be a small-area fan shape and is arranged at the bottom corner position of both sides of the electronic device. For another example, when the user performs single-hand typing in a chat interface, it is a single-hand input state, and a false touch is likely to occur at this time. Therefore, the preset region can be a large-area rectangular shape and is arranged at the bottom corner position and the middle position of the edge of one side of the electronic device.

[0136] In addition, when the preset region is arranged, the size and shape of the electronic device can also be considered. For example, when the electronic device is a small device, the touch screen thereof is small, and the preset region can be arranged at the edge of the touch screen. When the electronic device is a large device, the preset region can be arranged at some positions of the edge of the touch screen according to the user experience and use habit.

[0137] It should be noted that adjusting the preset region of the touch screen can be understood as adjusting and changing the position, shape, and size of the preset region of the touch screen provided with the preset region, or can be understood as arranging a preset region with a certain shape and a certain size at a certain position of the touch screen of the electronic device without the preset region.

[0138] Specifically, when it is a single-hand input state, the preset region is adjusted to the left edge region, taking left-hand typing as an example. Specifically, as shown in FIG. 2, the preset region is adjusted to the left edge region of the touch screen. Figure 2 、 Figure 3 、 Figure 4As shown, the preset area can be the bottom left corner area, or the preset area can include the bottom left corner area and the middle left edge area, or the preset area can include the entire left side of the touchscreen. Of course, when typing with your right hand, the adjustment of the preset area is similar to that when typing with your left hand.

[0139] like Figure 5 , Figure 6 As shown, when typing with both hands, the possibility of accidental touches is relatively small. Therefore, a preset area can be set including a left corner area and a right corner area. The area of ​​the left corner area when typing with both hands is smaller than the area of ​​the left corner area when typing with the left hand, and the area of ​​the right corner area when typing with both hands is smaller than the area of ​​the right corner area when typing with the right hand. To further improve the accuracy of accidental touch detection, the shape of the preset area can also be set to a fan shape or other shapes.

[0140] The positions and shapes of the preset areas mentioned above are for illustrative purposes only. When making specific settings, you can also consider the application scenarios of the accidental touch detection method, the size of the electronic device, the users of the electronic device, and so on.

[0141] In some embodiments, step 102 includes: when the touch input state is a single-handed input state or a two-handed input state, determining the current pressure distribution parameter based on the touch data corresponding to the first touch operation; wherein the pressure parameter is used to characterize the pressure distribution trend of the first touch operation. Step 103 includes: when the current pressure distribution parameter is greater than a preset force distribution threshold, not responding to the first touch operation.

[0142] In this embodiment, accidental touch detection includes calculating pressure distribution parameters when in single-handed or two-handed input mode. It is understood that when a finger performs a touch operation on a touchscreen, the pressure across the entire touch area is not uniform. In the case of an accidental touch, the center of pressure is biased towards the edge of the touchscreen, meaning the pressure is greater at the edges and less in the non-edge areas. In the case of a normal touch operation, the center of pressure is generally not at the edge of the touchscreen, meaning the pressure is greater in the non-edge areas and less in the edge areas. Therefore, by determining whether the pressure distribution parameters are greater than a preset force distribution threshold, it can be determined whether the first touch operation is an accidental touch, and based on this, whether to respond to the first touch operation.

[0143] Furthermore, based on the touch data corresponding to the first touch operation, the current pressure distribution parameters are determined, including: when the touch input state is a single-handed input state, the touch area when the first touch operation is applied to a preset area is one, and there is no touch operation in the non-preset area of ​​the touch screen, the current pressure distribution parameters are determined based on the touch data corresponding to the first touch operation.

[0144] Specifically, when the input state is the single-hand input state, the first touch operation only acts on the preset area, and the number of touch areas in the preset area is one, the calculation of the pressing force distribution parameter is performed.

[0145] In an embodiment, the step 102 comprises: in the case that the input state of the touch input is the single-hand input state, determining the area of the finger touch area and the area of the palm touch area based on the touch data corresponding to the first touch operation; and the step 103 comprises: in the case that the area of the finger touch area is less than the area of the palm touch area, not responding to the first touch operation.

[0146] In the embodiment, the false touch detection comprises: in the single-hand typing, calculating the area of the finger touch area and the area of the palm touch area. It can be understood that, in the single-hand typing, if it is a false touch operation, the area of the finger touch area will be less than the area of the palm touch area; if it is a normal touch operation, the area of the finger touch area will certainly be greater than the area of the palm touch area. In the double-hand typing, the palm is generally not easy to produce a false touch operation, therefore, in the double-hand typing, the calculation of the area of the finger touch area and the area of the palm touch area is not performed.

[0147] Further, the determination of the area of the finger touch area and the area of the palm touch area based on the touch data corresponding to the first touch operation comprises: in the case that the first touch operation simultaneously acts on the preset area and the non-pre-set area of the touch screen, or in the case that the number of touch areas when the first touch operation acts on the preset area is multiple and there is no touch operation in the non-pre-set area of the touch screen, the area of the finger touch area and the area of the palm touch area are determined based on the sensor touch data corresponding to the first touch operation.

[0148] Based on the above embodiments, it can be summarized that, when the input state is the single-hand input state, the contents of the false touch detection in different touch situations are different, it can be determined whether it is a false touch by only calculating the pressing force distribution parameter, or it can be determined whether it is a false touch by calculating the pressing force distribution parameter, the area of the finger touch area and the area of the palm touch area. When the input state is the double-hand input state, it can be determined whether it is a false touch by only calculating the pressing force distribution parameter.

[0149] Specifically, when being the single-hand input state, (1) when the first touch operation acts on both the preset region and the non-preset region, the press intensity distribution parameter of the touch data in the preset region is calculated, and the area of the finger touch region and the area of the palm touch region of the touch data in the preset region and the non-preset region are calculated; (2) when the first touch operation acts on one touch region in the preset region, and there is no touch operation in the non-preset region, the press intensity distribution of the touch data in the preset region is calculated; (3) when the first touch operation acts on multiple touch regions in the preset region, and there is no touch operation in the non-preset region, the press intensity distribution parameter, the area of the finger touch region and the area of the palm touch region of the touch data in the preset region are calculated.

[0150] That is, the calculation of the press intensity distribution parameter is only based on the sensor touch data in the preset region, while the calculation of the area of the finger touch region and the area of the palm touch region may be based only on the touch data in the preset region, or may need to use the touch data in both the preset region and the non-preset region.

[0151] Specifically, the press intensity distribution parameter includes: a corner press intensity distribution parameter and / or an edge press intensity distribution parameter.

[0152] If the coordinate corresponding to the maximum value in the touch data is the top corner position of the touch screen, the first sum of the touch data in the first L-shaped region containing the maximum value and the second sum of the touch data in the second L-shaped region adjacent to the first L-shaped region are determined, and the corner press intensity distribution parameter is determined based on the ratio between the first sum and the second sum; and / or;

[0153] If the coordinate corresponding to the maximum value is a non-top corner position of the touch screen, the third sum of at least one touch data in the direction of the straight line where the maximum value is located and the fourth sum of at least one touch data in the direction of the straight line adjacent to the straight line where the maximum value is located are determined, and the edge press intensity distribution parameter is determined based on the ratio between the third sum and the fourth sum.

[0154] In this embodiment, the calculation of the press intensity distribution parameter determines the specific calculation method of the press intensity distribution parameter according to the position of the coordinate corresponding to the maximum value in the touch data on the touch screen. It can be understood that there are multiple sensors arranged in an array in the display module of the electronic device, and 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 a corresponding coordinate in the touch screen. The maximum value in the touch data is the position with the maximum press intensity, i.e., the center of gravity of the touch operation.

[0155] For example, when the first touch operation acts on one touch region in the preset region, and there is no touch operation in the non-preset region, the press intensity distribution of the touch data in the preset region is calculated. Figure 7For 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 7 The 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.

[0156] by Figure 8 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 8 (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 8 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.

[0157] Furthermore, the methods for determining the finger touch area and palm touch area differ depending on the type of typing touch operation. Specifically, when the first touch operation simultaneously acts on a preset area and a non-preset area of ​​the touchscreen, the area containing the touch data corresponding to the first touch operation within the preset area is designated as the palm touch area; the area containing the touch data corresponding to the first touch operation within the non-preset area is designated as the finger touch area.

[0158] When the number of touch areas is multiple when the first touch operation is applied to the preset area, and there is no touch operation in the non-preset area of ​​the touch screen, multiple touch areas are determined based on the touch data and coordinates of the touch data corresponding to the first touch operation; curve fitting is performed on each touch area to obtain elliptical areas and non-elliptical areas; the elliptical areas are determined as finger touch areas, and the non-elliptical areas are determined as palm touch areas.

[0159] In this embodiment, when it is a one-handed input state, and the first touch operation is applied to both the preset area and the non-preset area, the hand operation is similar to Figure 2 As shown, it is assumed that the touch data applied to areas other than the preset area is the finger, and the touch data applied to the preset area is the palm. Therefore, the area where the sensor touch data is located within the preset area is taken as the palm touch area, and the area where the sensor touch data is located outside the preset area is taken as the finger touch area.

[0160] When the first touch operation only acts on the preset area and the number of touch areas in the preset area is multiple, the hand operation is similar to Figure 3 As shown, the multiple touch areas need to be identified to determine the finger touch area and the palm touch area. Specifically, the shapes of the multiple touch areas are identified by curve fitting, and when the touch area can be fitted as an elliptical area, the touch area is determined as a finger touch area. When the touch area is fitted as a non-elliptical area, the touch area is determined as a palm touch area.

[0161] Based on the above embodiments, the anti-mistouch method of the present disclosure determines the setting adjustment strategy of the preset area based on the input state of the touch input. In the case where the first touch operation acts on the preset area, the specific operation of the mistouch detection is determined according to the input state of the touch input, whether the first touch operation acts on the non-pre-set area, and the number of touch areas in the preset area. The entire method can reduce the amount of touch data calculation while achieving high accuracy in mistouch detection for various typing touch conditions under various input states of touch input.
