Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] The electronic device may be a portable electronic device that also includes other functions such as a personal digital assistant and / or a music player function, such as a mobile phone, a tablet computer, a wearable electronic device with wireless communication function (such as a smart watch, smart glasses, a smart helmet), a vehicle-mounted device, etc. Exemplary embodiments of portable electronic devices include but are not limited to portable electronic devices equipped with an IOS system, an Android system, a Microsoft system, or other operating systems. The above-mentioned portable electronic device may also be other portable electronic devices, such as a laptop computer (Laptop), etc. It should also be understood that in some other embodiments, the above-mentioned electronic device may also be the electronic device in the solution of this application.

[0031] To better understand this application, please refer to Figure 1 , Figure 1 : This is a flow chart of a touch area calculation method provided in an embodiment of the present application:

[0032] Specifically, if Figure 1 As shown:

[0033] S101. Expand a first touch area and a second touch area to obtain a touch area to be measured, wherein the first touch area is used to represent the area covered by a touch operation in a vertical direction, the second touch area is used to represent the area covered by the touch operation in a horizontal direction, and the touch area to be measured includes at least one node to be measured.

[0034] In a possible example, before determining the touch area to be measured, press touch difference data is collected.

[0035] The press touch difference data includes a node difference of at least one node in the frame data at the current moment, and the node difference is used to represent a node change amount of each of the nodes.

[0036] For example, touch-press difference data refers to the change in the touch signal detected and recorded when a user presses on the touch screen of an electronic device. When a user presses on the touch screen, the touch sensor captures the touch signal and converts it into digital data. This data can represent information such as the location, force, and speed of the touch. Touch-press difference data refers to the change in the value, i.e., the difference, obtained by comparing this data at the current moment with the touch state at a previous moment. The touch-press difference data corresponding to each moment corresponds to a frame of data, and each frame of data contains the node difference generated by the user's touch operation at the current moment for each node in at least one node.

[0037] For example, see Figure 2A and Figure 2B , Figure 2A A schematic diagram of a scenario in which a user touches a touch screen of an electronic device provided in this application solution. Figure 2B A schematic diagram of frame data corresponding to the current moment provided by the present application solution.

[0038] Specifically, the user performs a touch operation on the electronic device display screen through a finger, and controls the area covered by the current touch operation with different strengths.

[0039] For example, Figure 2A In the application scenario shown, the user selects a target translation sentence by pressing and touching the touch screen of the electronic device. For example, the current user's touch operation target is to select "Good morning" and the target is to translate it into English.

[0040] Furthermore, the electronic device sensor detects the user's touch operation and collects the frame data corresponding to the touch operation at the current moment, such as Figure 2B As shown in Figure 2. Among them, the node is the smallest unit in the touch unit, that is, Figure 2B Each small square shown.

[0041] For example, Figure 2A Take the scenario as an example, Figure 2B The image shows the current moment's touch difference data for the entire electronic device's touchscreen. The darker areas represent the interpolated touch data corresponding to the user's touch on the target area (i.e., the area containing the word "Good Morning"). The lighter areas represent areas not touched by the user.

[0042] For example, by analyzing the touch-press difference data, the following information can be obtained:

[0043] Position change: The change in touch position can be measured as the difference in touch coordinates. This can help determine the direction and distance the user's finger or stylus has moved on the screen.

[0044] Force changes: Changes in the intensity of the touch signal can reflect changes in the user's pressure. Larger differences may indicate that the user applied more force, while smaller differences may indicate a slight adjustment in the pressure.

[0045] Speed ​​change: The speed at which a touch signal changes can reveal how quickly the user is pressing. Large differences may indicate a fast swipe or drag, while smaller differences may indicate slow or subtle movements.

[0046] Furthermore, a first touch area and a second touch area are determined based on the press touch difference data, wherein the first touch area is used to characterize the area covered by the touch operation in the vertical direction, and the second touch area is used to characterize the area covered by the touch operation in the horizontal direction, and the area is composed of one or more nodes.

[0047] For example, Figure 2A As shown in the figure, when the user's finger touches the touch screen, the touch screen will detect an area value, which reflects the size of the touch area. In actual touch scenarios, when the finger touches the touch screen, it will generate a vertical force, that is, a downward force, and a pressing force along the horizontal axis of the contact surface between the finger and the display screen. These correspond to different touch areas. The electronic device will detect the area value based on the acquired information. Figure 2B The touch pressure difference data shown is used to determine the first touch area and the second touch area.

[0048] Among them, the first touch area is used to characterize the main touch area: it refers to the contact area between the finger and the touch screen in the vertical direction, that is, the height of the touch area. It indicates the actual touch area size of the finger on the screen. In most cases, the touch screen device will use the main touch area as an input signal to interpret the user's instructions or operations. The second touch area is used to characterize the touch area in the horizontal direction: it refers to the size of the contact area between the finger and the touch screen in the horizontal (horizontal) direction, that is, the width of the touch area. This concept is mainly used to describe the size of the horizontal range when the finger slides or touches the screen. It can be used to detect the sliding speed, direction, and horizontal gesture operations of the finger.

[0049] The first touch area and the second touch area are respectively represented by at least one node.

[0050] For example, when a user's finger contacts the touchscreen, the edge of the finger also exerts pressure on the touchscreen. Due to the smaller contact area, the change in node difference is less noticeable. However, this pressed area still falls within the current pressed touch area. Therefore, the electronic device performs a horizontal and vertical expansion process based on the first and second touch areas determined in step S102 to obtain a new pressed touch area, i.e., the touch area to be tested.

[0051] The touch pressing area to be tested includes at least one node to be tested, and the nodes to be tested include but are not limited to nodes corresponding to the first touch area and the second touch area and nodes after edge expansion processing. Each node to be tested corresponds to a node difference, such as Figure 2B The value in each grid shown is the node difference corresponding to the node represented by the current grid.

[0052] S102: Determine the node to be measured that is greater than a preset threshold as a target node, wherein the target node includes one or more nodes.

[0053] For example, the electronic device determines at least one target node based on the magnitude relationship between the node difference of each node to be measured and a preset threshold. In the present application, the preset threshold can be 30 for comparison. In actual scenarios, different preset thresholds can be determined based on actual usage habits.

[0054] For example, if there is a node to be measured that is greater than a preset threshold, the current node is determined to be a valid node for calculation, that is, the node is determined to be the target node. If the node to be measured is less than or equal to the preset threshold, it indicates that there may be an accidental touch or invalid touch in the current area, and the node is not included in the calculation scope.

[0055] Exemplarily, each node to be tested that is greater than a preset threshold is determined as a target node.

[0056] S103. Determine a first effective touch area corresponding to the current moment based on the at least one target node and the area maximum value, wherein the area maximum value is used to represent the farthest distance between the touch point and the channel where the controller of the touch screen is located when the user performs the touch operation on the touch screen.

[0057] Illustratively, in the solution of the present application, the maximum value of the region is used as a standard reference, and the first effective touch area corresponding to the current moment is determined by comparing the target node with the maximum value of the region.

[0058] It is important to note that the specific design and technology of touch screens may vary, so the maximum distance between the touch point and the controller may vary. Manufacturers usually provide relevant parameters of the touch screen in the product specifications so that users can understand the performance and limitations of the device.

[0059] S104: Acquire a second effective touch area and a third effective touch area respectively corresponding to two historical moments adjacent to the current moment.

[0060] S105: Determine a target effective touch area according to the first effective touch area, the second effective touch area, and the third effective touch area.

[0061] For example, the second and third effective touch areas are both calculated using the process described in steps S101-S105 above. Since the area values ​​obtained through steps S101-S105 are unstable and subject to jitter, it is considered to smooth the historical area values ​​to obtain a more accurate target effective touch area. That is, the electronic device obtains historical effective touch area data at adjacent moments, smooths them according to the corresponding smoothing coefficients at different moments, and then accumulates them to obtain the final target effective touch area.

[0062] As can be seen, the embodiment of the present application discloses a touch area calculation method. The electronic device performs edge expansion processing on the first touch area and the second touch area to obtain the touch area to be measured; determines at least one target node based on the node difference corresponding to each node to be measured and a preset threshold; determines the first effective touch area corresponding to the current moment based on the at least one target node and the maximum value of the area; obtains the second effective touch area and the third effective touch area corresponding to two moments adjacent to the current moment; and determines the target effective touch area based on the first effective touch area, the second effective touch area, and the third effective touch area. In this way, the actual effective area value can be obtained by calculating the pressed touch difference data in a specific manner, thereby improving the accuracy of touch area calculation.

[0063] In a possible example, the edge expansion processing includes longitudinal edge expansion processing and transverse edge expansion processing; the edge expansion processing of the first touch area and the second touch area to obtain the touch area to be tested may include the following steps: setting the edge expansion node value; performing the longitudinal edge expansion processing according to the edge expansion node value and the first touch area to obtain the first area to be tested; performing the transverse edge expansion processing according to the edge expansion node and the second touch area to obtain the second area to be tested; combining the first area to be tested and the second area to be tested to obtain the touch area to be tested.

[0064] For example, a touch screen device has a predefined touch-sensitive area where the user needs to place a finger or stylus to perform a touch operation. However, in some cases, the user may accidentally touch or inadvertently perform a touch operation on the edge area, which may result in unexpected responses or operational difficulties.

[0065] For example, to address this issue, the present application employs a touch area expansion process. Specifically, an additional inactive area is added around the touch-sensitive area and treated as part of the effective touch area. When a user touches the edge of the touch-sensitive area, the system maps the touch to the effective touch area and performs the corresponding response or operation.

[0066] Exemplarily, in the present application, the above-mentioned expansion node value is preset to 1, and the edge expansion processing is performed along the horizontal and vertical directions respectively with the expansion node value being 1. The edge of the current first touch area is expanded by one node along the vertical direction, and the edge of the second touch area is expanded by one node along the horizontal direction, to obtain a new touch area, namely the touch area to be tested.

[0067] As can be seen, in the embodiments of the present application, by expanding the touch area, the occurrence of false touches can be reduced, a larger touchable area can be provided, and thus the user experience can be improved. This edge expansion processing technology is commonly used in modern smartphones, tablets, and other touch screen devices to enhance the accuracy and reliability of operations.

[0068] In one possible example, the touch screen is divided into at least one area, and the area is used for sensor detection and positioning of the user's press; before determining the first effective touch area corresponding to the current moment based on the target node and the area maximum value, the above method also includes the following steps: obtaining sensor data of the electronic device; determining the signal strength value corresponding to each of the areas based on the sensor data, wherein the signal strength value is used to characterize the touch intensity of the user; and determining the maximum signal strength value as the area maximum value.

[0069] For example, in sensor technology, the touch screen of an electronic device can be divided into at least one region or channel for detecting and locating user presses. The regional maximum value indicates the channel or region with the strongest touch intensity or regional value among all channels or regions. The single-channel distance indicates the distance between the user's press location and the channel or region.

[0070] It can be seen that in the embodiment of the present application, the electronic device can obtain sensor data and determine the maximum value of the area based on the sensor data, thereby using the maximum value of the area as a standard to calculate the target effective touch area.

[0071] In one possible example, the method may further include the following steps: performing cumulative calculation based on the node difference corresponding to each target node in the at least one target node to obtain a first cumulative value; determining the area value corresponding to the current moment based on the ratio between the first cumulative value and the regional maximum value; and determining the first effective touch area based on the area value corresponding to the current moment and a first smoothing coefficient.

[0072] Exemplarily, the electronic device determines at least one target node in step S102 and accumulates the node difference corresponding to each target node to obtain a corresponding accumulated sum, namely, a first accumulated value.

[0073] Furthermore, the area value corresponding to the current moment is determined based on the ratio of the first accumulated value to the regional maximum value. At this point, the area value is used to determine the true effective touch range of the touch area. The main significance of this effective range is that the effective press distance is defined as the regional maximum value, and the ratio of other nodes to the regional maximum value is used to determine the true size of the distance occupied by other nodes.

[0074] Furthermore, a first effective touch area is determined according to the product of the area value corresponding to the current moment and the first smoothing coefficient.

[0075] As can be seen, through the method proposed in this example, the electronic device uses the maximum area value as the effective touch pressure of the standard single-channel distance, and then compares the cumulative sum of the node differences of the target node with it to determine the true value of the distance occupied by other nodes. Furthermore, smoothing is performed based on the product of the true value and its coefficient to obtain the first effective touch area.

[0076] In one possible example, the method may further include the following steps: determining the first effective touch area corresponding to the current moment based on the target node and the area maximum value: determining the area maximum value as the standard value; respectively calculating the ratio between the node difference corresponding to each target node and the standard value, wherein the ratio is used to characterize the effective pressing range of the area corresponding to each target node to the area corresponding to the standard value; and obtaining the first effective touch area based on the cumulative sum of the first smoothing coefficient and the ratio corresponding to each target node.

[0077] For example, by using the regional maximum as a criterion, a valid press by the user can be identified as a touch operation within the single channel distance corresponding to the regional maximum. If the user presses too far from the channel or region corresponding to the regional maximum, the system may consider it an invalid press.

[0078] For example, determining the ratio of the node difference value corresponding to each node to the standard value can help eliminate some erroneous operations or abnormal situations, ensuring that only presses within a range close to the regional maximum value are considered valid touch operations. This helps improve the accuracy and reliability of touch location in touchscreen devices.

[0079] For example, if the channel distance where the regional maximum value is located is N, and the ratio of another node to the regional maximum value is 0.5, it means that the effective pressing range of this node is also half of the channel area. Based on this principle, the effective pressing ranges of all nodes in the area are accumulated to obtain the final touch area.

[0080] It can be seen that through the method proposed in this example, the area maximum value is used as the effective press of the standard single-channel distance, and the ratio of the node difference corresponding to each node to the area maximum value is determined respectively, that is, the distance between the area where each node is located and the area corresponding to the area maximum value, so as to determine the actual effective pressing area ratio of each node, and then multiply the actual effective pressing area of ​​each target node and its corresponding coefficient to obtain the first effective touch area.

[0081] In a possible example, before determining the target effective touch area based on the first effective touch area, the second effective touch area and the third effective touch area, the above method may further include the following steps: setting the first smoothing coefficient, the second smoothing coefficient and the third smoothing coefficient corresponding to the first effective touch area, the second effective touch area and the third effective touch area respectively.

[0082] For example, the smoothing coefficient corresponding to different moments is an empirical value obtained by statistically analyzing the ratio of the calculated value to the actual physical value. Multiple statistical data and user usage data can be used to obtain a more accurate smoothing coefficient.

[0083] It can be seen that in the embodiment of the present application, the electronic device determines the smoothing coefficients corresponding to the effective touch areas calculated at historical moments based on relevant data during the actual use of the electronic device, and can more accurately determine the impact of the effective touch areas calculated at historical moments on the effective touch area at the current moment, thereby being more conducive to the accuracy of the calculation of the target effective touch area corresponding to the current moment.

[0084] In one possible example, the target effective touch area value is determined based on the first effective touch area, the second effective touch area and the third effective touch area. The method may also include the following steps: calculating the first touch area value based on the first effective touch area and the first smoothing coefficient; calculating the second touch area value based on the second effective touch area and the second smoothing coefficient; calculating the third touch area value based on the third effective touch area and the third smoothing coefficient; and obtaining the target effective touch area based on the first touch area value, the second touch area value and the third touch area value.

[0085] For example, in the present application, the calculation formula for the final target effective touch area is:

[0086] TouchMajor ＝ (curTouchMajor*SMOOTH_CUR_COOR_RATIO+lastTouchMajor*

[0087] SMOOTH_LAST_COOR_RATIO+lastLastRxTouchMajor*SMOOTH_LLAST_COOR_RATIO) / SMOOTH_BASE_COOR_RATIO.

[0088] TouchMajor represents the target effective touch area; curTouchMajor represents the current touch area, also known as the first effective touch area; lastTouchMajor and lastLastRxTouchMajor represent the effective touch areas corresponding to the two historical moments adjacent to the current moment. SMOOTH_CUR_COOR_RATIO, SMOOTH_LAST_COOR_RATIO, and SMOOTH_LLAST_COOR_RATIO represent the first, second, and third smoothing coefficients, respectively; and SMOOTH_BASE_COOR_RATIO represents the cumulative sum of these three smoothing coefficients.

[0089] It can be seen that in the embodiment of the present application, the electronic device improves the accuracy of touch area calculation by integrating the effective touch area at historical moments into the actual effective area value obtained by calculating the press touch difference data in a specific manner.

[0090] The above mainly introduces the solution of the embodiment of the present application from the perspective of the execution process of the method side. It is understandable that, in order to realize the above functions, the electronic device includes a hardware structure and / or software module corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the units and algorithm steps of each example described in the embodiment provided herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in a hardware or computer software driven hardware manner depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of this application.

[0091] The embodiment of the present application can divide the functional units of the electronic device according to the above method example. For example, each functional unit can be divided according to each function, or two or more functions can be integrated into one processing unit. The above integrated unit can be implemented in the form of hardware or in the form of software functional units. It should be noted that the division of units in the embodiment of the present application is schematic and is only a logical function division. There may be other division methods in actual implementation.

[0092] and Figure 1 For details, please refer to Figure 3 , Figure 3 FIG. 1 is a structural diagram of a touch area calculation device provided in an embodiment of the present application. Figure 3 As shown, the touch area calculation device 300 includes: a processing unit 301, a determination unit 302 and an acquisition unit 303, wherein:

[0093] The processing unit 301 is configured to perform edge expansion processing on the first touch area and the second touch area to obtain a touch area to be measured, wherein the first touch area is used to represent the area covered by the touch operation in the vertical direction, the second touch area is used to represent the area covered by the touch operation in the horizontal direction, and the touch area to be measured includes at least one node to be measured;

[0095] The determining unit 302 is further configured to determine a first effective touch area corresponding to the current moment based on the target node and the area maximum value, wherein the area maximum value is used to represent the maximum distance between the touch point and the channel where the controller of the touch screen is located when the user performs the touch operation on the touch screen;

[0096] The acquiring unit 303 is configured to acquire a second effective touch area and a third effective touch area respectively corresponding to two historical moments adjacent to the current moment;

[0097] The determining unit 302 is further configured to determine a target effective touch area according to the first effective touch area, the second effective touch area, and the third effective touch area.

[0098] As can be seen, the embodiment of the present application discloses a touch area calculation device. The electronic device uses a processing unit to perform edge expansion processing based on the first touch area and the second touch area to obtain a touch area to be measured; the determination unit determines at least one target node based on the node difference corresponding to each node to be measured and a preset threshold; the determination unit determines the first effective touch area corresponding to the current moment based on the at least one target node and the maximum value of the area; the acquisition unit obtains the second effective touch area and the third effective touch area corresponding to two adjacent moments of the current moment; the determination unit determines the target effective touch area based on the first effective touch area, the second effective touch area, and the third effective touch area. In this way, the actual effective area value can be obtained by calculating the pressed touch difference data in a specific manner, thereby improving the accuracy of the touch area calculation.
