Description

Technical Field

[0001] The present application relates to the field of smart terminal technology, and in particular to a touch detection method and related equipment. Background Art

[0002] The touchpad is an important medium for users to interact with electronic devices such as laptops and tablets. Users can simulate the functions of a mouse by clicking, pressing, and sliding the touchpad with their fingers. However, when using electronic devices, users are prone to accidentally touching the touchpad, which in turn leads to incorrect operations. For example, to facilitate user input operations, the touchpad is usually located near the keyboard and at a relatively close distance. Therefore, due to the relative position relationship between the keyboard and the touchpad, when the user's fingers touch the keyboard, the palm or the side of the finger often touches the touchpad, causing accidental touches on the touchpad, thereby affecting the user's experience. Summary of the Invention

[0003] In view of the above, it is necessary to provide a touch detection method and related equipment to solve the technical problem that users easily touch the touchpad by mistake.

[0004] In a first aspect, the present application provides a touch detection method, which includes: in response to a user's touch operation on a touch pad, collecting a touch area generated by the touch operation on the touch pad; calculating a current direction angle corresponding to the touch operation based on the touch area; calculating a difference between the current direction angle and a historical direction angle corresponding to at least one historical touch operation to obtain at least one first direction angle difference; if the at least one first direction angle difference is less than or equal to a first threshold, executing a corresponding preset function based on the touch operation.

[0005] Through the above technical solution, the corresponding preset function can be executed based on the touch operation only when the direction angle corresponding to the current touch operation is slightly different from the direction angle of the previous touch operation, effectively preventing accidental touches and avoiding erroneous operations.

[0006] In one possible implementation, calculating the current direction angle corresponding to the touch operation based on the touch area includes: determining a minimum rectangular frame that includes the touch area; determining two opposite endpoints of the minimum rectangular frame as reference points; determining the vertical distance and lateral distance between the two reference points; and calculating the current direction angle corresponding to the touch operation based on the vertical distance and lateral distance between the two reference points. This technical solution allows for accurate calculation of the direction angle of the touch operation.

[0007] In one possible implementation, determining the minimum rectangular frame encompassing the touch area includes: determining the upper, lower, left, and right endpoints of the touch area; determining a first straight line passing through the upper endpoint and parallel to the horizontal edge of the touchpad; determining a second straight line passing through the lower endpoint and parallel to the horizontal edge of the touchpad; determining a third straight line passing through the left endpoint and perpendicular to the horizontal edge of the touchpad; and determining a fourth straight line passing through the right endpoint and perpendicular to the horizontal edge of the touchpad; and determining the rectangular frame enclosed by the first, second, third, and fourth straight lines as the minimum rectangular frame encompassing the touch area. Through the above technical solution, the rectangular frame corresponding to the touch operation can be accurately determined, improving the accuracy of directional angle calculation.

[0008] In a possible implementation, determining the two opposite endpoints of the minimum rectangular frame as reference points includes: respectively calculating the distances between the two endpoints below the minimum rectangular frame and the lower endpoint of the touch area; if the distance between the lower left endpoint of the minimum rectangular frame and the lower endpoint of the touch area is less than or equal to the distance between the lower right endpoint of the minimum rectangular frame and the lower endpoint of the touch area, determining the lower left endpoint of the minimum rectangular frame as the first reference point, and determining the endpoint on the minimum rectangular frame opposite to the first reference point as the second reference point; or if the distance between the lower left endpoint of the minimum rectangular frame and the lower endpoint of the touch area is greater than the distance between the lower right endpoint of the minimum rectangular frame and the lower endpoint of the touch area, determining the lower right endpoint of the minimum rectangular frame as the first reference point, and determining the endpoint on the minimum rectangular frame opposite to the first reference point as the second reference point. Through the above technical solution, the reference point for calculating the direction angle of the touch operation can be accurately determined.

[0009] In a possible implementation, the calculation of the current direction angle corresponding to the touch operation based on the vertical distance and horizontal distance between the two reference points includes: if the second reference point is on the left side of the first reference point, based on the vertical distance and horizontal distance between the two reference points, calculating the angle between the line connecting the two reference points and the horizontal side length of the minimum rectangular frame; adding 90 degrees to the angle between the line connecting the two reference points and the horizontal side length of the minimum rectangular frame to obtain the current direction angle corresponding to the touch operation; or if the second reference point is on the right side of the first reference point, based on the vertical distance and horizontal distance between the two reference points, calculating the angle between the line connecting the two reference points and the horizontal side length of the minimum rectangular frame; determining the angle between the line connecting the two reference points and the horizontal side length of the minimum rectangular frame as the current direction angle corresponding to the touch operation. Through the above technical solution, the direction angle corresponding to the touch operation can be accurately calculated based on the relative position between the first reference point and the second reference point.

[0010] In one possible implementation, the method further includes: if there is only one touch area, calculating the difference between the current direction angle and the historical direction angle corresponding to the at least one historical touch operation to obtain the at least one first direction angle difference; and if the at least one first direction angle difference is less than or equal to a first threshold, executing a preset function corresponding to the touch operation. This technical solution allows, when there is only one touch area, to determine whether the current touch operation is a false touch based on the difference in direction angles between consecutive touch operations, thereby effectively preventing false touches.

[0011] In one possible implementation, the method further includes: if there are multiple touch areas, calculating the difference between each two current direction angles to obtain at least one second direction angle difference; if the at least one second direction angle difference is less than or equal to a second threshold, executing a preset function corresponding to the touch operation; or if any second direction angle difference is greater than the second threshold, not executing the preset function corresponding to the touch operation. With the above technical solution, when there are multiple touch areas, it is possible to determine whether the current touch operation is a false touch based on the differences between the direction angles corresponding to the multiple touch areas, thereby effectively avoiding false touches.

[0012] In one possible implementation, in response to a user's touch operation on the touchpad, collecting a touch area on the touchpad generated by the touch operation includes: detecting the user's touch operation on the touchpad, collecting touch position information of the touch operation; and determining a touch area on the touchpad generated by the touch operation based on the touch position information. With the above technical solution, the touch area on the touchpad generated by the touch operation can be accurately determined.

[0013] In one possible implementation, collecting the touch position information of the touch operation includes: the sensing layer reporting the sensing channel and driving channel where the sensed capacitance changes to a touch driver module; the touch driver module obtaining the horizontal coordinate of the touch position based on the sensing channel where the sensed capacitance changes, and obtaining the vertical coordinate of the touch position based on the driving channel where the sensed capacitance changes. Through the above technical solution, the coordinate information of the touch position can be accurately determined.

[0014] In one possible implementation, collecting the touch position information of the touch operation includes: the sensing layer reporting the changed sensing capacitance's sensing channel and driving channel, as well as the changed sensing capacitance, to a touch driver module; if the changed sensing capacitance is greater than or equal to a preset sensing capacitance threshold, the touch driver module obtaining the horizontal coordinate of the touch position based on the sensing channel where the changed sensing capacitance is located, and obtaining the vertical coordinate of the touch position based on the driving channel where the changed sensing capacitance is located. Through the above technical solution, the coordinate information of the touch position can be accurately determined.

[0015] In one possible implementation, determining the touch area on the touchpad generated by the touch operation based on the touch position information includes determining an area formed by the coordinates of multiple touch positions of the touch operation as the touch area on the touchpad generated by the touch operation. Through the above technical solution, the touch area on the touchpad generated by the touch operation can be accurately determined.

[0016] In one possible implementation, executing a corresponding preset function based on a touch operation includes: determining the coordinates of the center of gravity of the touch area using a barycenter algorithm based on the coordinates of multiple touch positions within the touch area, and using the barycenter coordinates as the reporting point information generated by the touch operation; and executing the preset function corresponding to the touch operation based on the reporting point information. With the above technical solution, when it is determined that the touch operation is not an accidental touch, the reporting point corresponding to the touch operation can be accurately determined, thereby executing the corresponding preset function based on the reporting point.

[0017] In one possible implementation, the method further includes: if the at least one first directional angle difference is greater than a first threshold, not executing a preset function corresponding to the touch operation. This technical solution can effectively prevent accidental touches by not executing the preset function corresponding to the touch operation when the directional angles corresponding to multiple touch operations differ significantly.

[0018] In a second aspect, the present application provides an electronic device, comprising a memory and a processor: wherein the memory is used to store program instructions; the processor is used to read and execute the program instructions stored in the memory, and when the program instructions are executed by the processor, the electronic device performs the above-mentioned touch detection method.

[0019] In a third aspect, the present application provides a chip coupled to a memory in an electronic device, wherein the chip is used to control the electronic device to execute the above-mentioned touch detection method.

[0020] In a fourth aspect, the present application provides a computer storage medium storing program instructions. When the program instructions are executed on an electronic device, the electronic device executes the above-mentioned touch detection method.

[0021] In addition, the technical effects brought about by the second to fourth aspects can be found in the descriptions of the methods of each design in the above method section, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] In the absence of conflict, the following embodiments and features thereof may be combined with each other.

[0047] The touchpad is an important medium for users to interact with electronic devices such as laptops and tablets. Users can simulate the functions of a mouse by clicking, pressing, sliding, and other operations on the touchpad with their fingers. However, when using electronic devices, users are prone to accidentally touching the touchpad, which in turn causes erroneous operations, thus affecting the user's experience. For example, in order to facilitate user input operations, the touchpad is usually set near the keyboard and at a close distance. In this way, due to the relative position relationship between the keyboard and the touchpad, when the user's fingers touch the keyboard, the palm or the side of the finger often touches the touchpad, causing an accidental touch of the touchpad. For another example, when the user is moving an electronic device, the finger is also likely to touch the touchpad, causing an accidental touch of the touchpad.

[0048] In order to avoid erroneous operation caused by accidentally touching the touch panel, the embodiment of the present application provides a touch detection method. In order to better understand the touch detection method provided by the embodiment of the present application, the following is combined with Figure 1A 、 Figure 1B 、 Figure 1C 、 Figure 1D The application scenario of the touch detection method of the embodiment of the present application is described.

[0049] See Figure 1A As shown, the touchpad of the laptop is set below the keyboard. When the user is typing on the laptop, based on the user's operating habits, the fingers are usually located in the keyboard area of ​​the laptop, and some fingers or palms may touch the touchpad, forming the following on the touchpad: Figure 1B The touch area shown. When the user is typing, as the palm moves irregularly, the position of the touch area formed on the touchpad is also irregular.

[0050] See Figure 1C As shown, when the user moves the laptop computer while it is open and closed, based on the user's operating habits, the four fingers other than the thumb and the palm support the bottom of the laptop computer, and the thumb presses the touchpad, forming a mark on the touchpad. Figure 1D The touch area shown.

[0051] See Figure 2 The figure shows the software architecture of an electronic device provided in an embodiment of the present application. A layered architecture divides software into several layers, each with distinct roles and divisions of labor. Layers communicate with each other via software interfaces. For example, the operating system of an electronic device is divided into four layers: application layer 101, framework layer 102, kernel layer 103, and hardware layer 104, from top to bottom.

[0052] The application layer can include a series of application packages. For example, an application package can include camera, gallery, calendar, map, navigation, WLAN, Bluetooth, music, video, short message and other applications.

[0053] The framework layer provides an application programming interface (API) and programming framework for applications in the application layer. The application framework layer includes some predefined functions. For example, the application framework layer may include a window manager, content provider, view system, resource manager, notification manager, etc.

[0054] The window manager manages window applications. It can obtain the display size, determine whether a status bar exists, lock the screen, and take screenshots. The content provider stores and retrieves data and makes it accessible to applications. This data can include video, images, audio, incoming and outgoing calls, browsing history and bookmarks, and the phone book. The view system includes visual controls, such as those for displaying text and images. The view system can be used to build applications. A display interface can consist of one or more views. For example, a display interface containing a text notification icon can include a view for displaying text and a view for displaying images. The resource manager provides applications with various resources, such as localized strings, icons, images, layout files, and video files. The notification manager enables applications to display notifications in the status bar. These messages can be displayed briefly and then disappear automatically, requiring no user interaction. For example, the notification manager is used to notify users of download completions and message reminders. The notification manager can also display notifications in the system's top status bar as icons or scrolling text, such as notifications from background applications, or as dialog windows. For example, a text message may be displayed in the status bar, a prompt sound may be emitted, the electronic device may vibrate, an indicator light may flash, etc.

[0055] The application and framework layers run in a virtual machine. The virtual machine executes Java files from the application and framework layers as binary files. The virtual machine manages object lifecycles, stack management, thread management, security and exception management, and garbage collection.

[0056] The kernel layer is the layer between hardware and software. The kernel layer includes at least display driver, camera driver, audio driver, and sensor driver.

[0057] The kernel layer is the core of an electronic device's operating system. It is the first layer of software expansion based on the hardware, providing the most basic operating system functions and forming the foundation of the operating system. It manages the system's processes, memory, device drivers, files, and network systems, and determines the system's performance and stability. For example, the kernel can determine when an application can operate on a certain piece of hardware.

[0058] The kernel layer includes programs closely related to the hardware, such as interrupt handlers and device drivers. It also includes basic, common, and high-frequency modules, such as the clock management module and the process scheduling module, as well as key data structures. The kernel layer can be installed in the processor or stored in internal memory.

[0059] The hardware layer includes the hardware of electronic devices, such as keyboards, touchpads, displays and other input and output devices.

[0060] See Figure 3 FIG. 1 is a flow chart of a touch detection method provided in an embodiment of the present application. The method is applied to an electronic device and includes:

[0061] S101 , in response to a touch operation performed by a user on a touch panel, collecting a touch area generated by the touch operation on the touch panel.

[0062] In one embodiment of the present application, in response to a user's touch operation on the touch panel, a detailed process of collecting the touch area generated by the touch operation on the touch panel is as follows: Figure 4 As shown, specifically including:

[0063] S1011 , detecting a user's touch operation on the touchpad, and collecting touch position information of the touch operation.

[0064] like Figure 2 As shown, the hardware layer 104 includes a touch panel 196, and the core layer 103 includes a touch driver module 1031. Figure 5 FIG. 1 is a schematic diagram of the structure of a touch panel provided in an embodiment of the present application. In one embodiment of the present application, the touch panel 196 includes a touch layer 201 and a sensing layer 202. The touch layer 201 is used for user touch, and the sensing layer 202 includes a plurality of sensing channels 203 and a plurality of driving channels 204. The plurality of sensing channels 203 and the plurality of driving channels 2044 are intersectingly distributed. The sensing channels 203 are provided with a plurality of sensing electrodes, and the driving channels 204 are provided with a plurality of driving electrodes. For example, see Figure 6 As shown, the sensing layer 202 includes 14 sensing channels 203 and 14 driving channels 204 .

[0065] In one embodiment of the present application, a touch operation is an operation in which a user touches a touchpad with a hand (e.g., a finger or palm). Detecting the user's touch operation on the touchpad and collecting touch position information of the touch operation includes: detecting the user's touch operation on the touchpad in real time through the sensing layer 202, and collecting touch position information of the touch operation in response to the touch operation when the touch operation is detected. The sensing layer 202 detects the user's touch operation on the touchpad at a preset sampling rate, and the sampling rate is the number of times the sensing layer collects touch signals per second. Optionally, the preset sampling rate is 120 Hz.

[0066] In one embodiment of the present application, the touch position information of the touch operation is the coordinate information of the touch position. The user can perform a touch operation on the touchpad with his hand, for example, the touch operation can be a click, a slide, etc. When the touchpad does not receive a touch operation, the sensing capacitance on the sensing channel and the driving channel is zero or a fixed value. When the touchpad receives a touch operation, since the user's hand is a conductor, it can generate a sensing capacitance with the sensing electrode on the sensing channel and the driving electrode on the driving channel, causing the sensing capacitance on the sensing channel and the driving channel to change.

[0067] Specifically, collecting touch position information of a touch operation includes: when a user's hand (finger or palm) touches the touchpad, the touchpad generates a change in induced capacitance at the intersection of the sensing channel and the drive channel where the hand touches the touchpad, the sensing layer reports the sensing channel and the drive channel where the induced capacitance change is located to the touch drive module, the touch drive module obtains the X-axis (horizontal axis) coordinate of the touch position based on the sensing channel where the induced capacitance change is located, and obtains the Y-axis (vertical axis) coordinate of the touch position based on the drive channel where the induced capacitance change is located. In this way, the touch drive module determines the touch position information of the touch operation by obtaining the X-axis coordinate and Y-axis coordinate of the touch position. The X-axis coordinate and the Y-axis coordinate are coordinates on a coordinate system established with the edge of the touchpad as the coordinate axis. In one example, the X-axis coordinate value is the number of the sensing channel, and the Y-axis coordinate value is the number of the drive channel.

[0068] In one embodiment of the present application, if the sensing channel is arranged along the horizontal direction of the touch pad and the driving channel is arranged along the vertical direction of the touch pad, the sensing channel obtains the X-axis coordinate of the touch position and the driving channel obtains the Y-axis coordinate of the touch position. In another embodiment of the present application, if the sensing channel is arranged along the vertical direction of the touch pad and the driving channel is arranged along the horizontal direction of the touch pad, the sensing channel obtains the Y-axis coordinate of the touch position and the driving channel obtains the X-axis coordinate of the touch position.

[0069] In another embodiment of the present application, collecting touch position information of a touch operation includes coordinate information of the touch position and induced capacitance. Collecting the reporting information generated by the touch operation includes: when the user's hand (finger or palm) touches the touchpad, the touchpad generates an induced capacitance change at the intersection of the sensing channel and the driving channel where the hand touches, the sensing layer reports the changed induced capacitance and the sensing channel and driving channel where the changed induced capacitance is located to the touch driver module, the touch driver module determines whether the changed induced capacitance is greater than or equal to a preset induced capacitance threshold, if the changed induced capacitance is greater than or equal to the preset induced capacitance threshold, the touch driver module obtains the X-axis coordinate of the touch position based on the sensing channel where the changed induced capacitance is located, and obtains the Y-axis coordinate of the touch position based on the driving channel where the changed induced capacitance is located. In this way, the touch driver module determines the coordinate information of the touch position based on the obtained X-axis coordinate and Y-axis coordinate of the touch position, and uses the changed induced capacitance as the induced capacitance of the touch position, thereby determining the touch position information of the touch operation. Optionally, the preset induced capacitance threshold is 200. In other embodiments, the preset sensing capacitance threshold can also be set to other values ​​according to requirements. The sensing capacitance is on the order of magnitude of the sensing capacitance, and is determined by converting the analog touch signal generated by the sensing layer based on the touch operation into a digital touch signal.

[0070] like Figure 6 As shown, 14 sensing channels and 14 driving channels are intersected to form multiple intersection areas. When the touch panel receives a touch operation from a user, the sensing layer generates a change in induced capacitance in the intersection area of ​​the sensing channels and the driving channels. The number in each intersection area represents the changed induced capacitance, and the unit of the induced capacitance is pico-farad. For example, the induced capacitance of the intersection area between the first sensing channel and the first driving channel is 44, which is less than a preset induced capacitance threshold of 200. The induced capacitance of the intersection area between the eighth sensing channel and the eighth driving channel is 756, which is greater than the preset induced capacitance threshold of 200. Therefore, the intersection area between the eighth sensing channel and the eighth driving channel is a touch position corresponding to the touch operation. The coordinates of the touch position are determined as (8, 8) based on the numbers of the sensing channels and the driving channels.

[0071] S1012: Determine a touch area generated by the touch operation on the touch panel based on the touch position information of the touch operation.

[0072] In one embodiment of the present application, determining a touch area generated by a touch operation on the touch panel based on touch position information of the touch operation includes: determining an area formed by coordinates of multiple touch positions of the touch operation as the touch area generated by the touch operation on the touch panel.

[0073] It can be understood that the intersection area where the induced capacitance after the change is greater than or equal to the preset induced capacitance threshold corresponds to a touch position, which is actually a touch point. The area formed by all touch points is the touch area generated by the touch operation on the touch panel. For example, see Figure 7 As shown, the dotted box area in the figure is an area formed by multiple touch points corresponding to multiple intersecting areas with an inductive capacitance greater than 200, that is, a touch area generated by a touch operation on the touch panel.

[0074] S102: Calculate a current direction angle corresponding to the touch operation based on the touch area.

[0075] In one embodiment of the present application, the detailed process of calculating the current direction angle corresponding to the touch operation based on the touch area is as follows: Figure 8 As shown, specifically including:

[0076] S1021: Determine the minimum rectangular frame that includes the touch area.

[0077] In one embodiment of the present application, determining the minimum rectangular frame including the touch area includes: determining the upper endpoint, lower endpoint, left endpoint, and right endpoint of the touch area, determining a first straight line passing through the upper endpoint and parallel to the horizontal edge of the touchpad, determining a second straight line passing through the lower endpoint and parallel to the horizontal edge of the touchpad, determining a third straight line passing through the left endpoint and perpendicular to the horizontal edge of the touchpad, determining a fourth straight line passing through the right endpoint and perpendicular to the horizontal edge of the touchpad, and determining a rectangular frame formed by the first straight line, the second straight line, the third straight line, and the fourth straight line as the minimum rectangular frame including the touch area.

[0078] In one embodiment of the present application, based on Figure 6 The numbering of the sensing channels and the driving channels shown in the figure, and determining the upper, lower, left, and right endpoints of the touch area include: determining the touch position with the smallest vertical coordinate in the touch area as the upper endpoint, determining the touch position with the largest vertical coordinate in the touch area as the upper endpoint, determining the touch position with the smallest horizontal coordinate in the touch area as the left endpoint, and determining the touch position with the largest horizontal coordinate in the touch area as the right endpoint. In other embodiments, the method for determining the upper, lower, left, and right endpoints of the touch area can be adaptively changed based on other numbering settings of the sensing channels and the driving channels.

[0079] For example, Figure 7As shown, a first straight line L1 passing through the upper endpoint a0 of the touch area and parallel to the horizontal edge of the touch panel is determined, a second straight line L2 passing through the lower endpoint b0 and parallel to the horizontal edge of the touch panel is determined, a third straight line L3 passing through the left endpoint c0 and perpendicular to the horizontal edge of the touch panel is determined, and a fourth straight line L4 passing through the right endpoint d0 and perpendicular to the horizontal edge of the touch panel is determined. A rectangular frame X formed by the first straight line L1, the second straight line L2, the third straight line L3, and the fourth straight line L4 is determined as the minimum rectangular frame including the touch area.

[0080] S1022: Determine two opposite endpoints of the minimum rectangular frame as reference points.

[0081] In one embodiment of the present application, determining the two opposite endpoints of the minimum rectangular box as reference points includes: respectively calculating the distances between the two endpoints below the minimum rectangular box and the lower endpoint of the touch area; if the distance between the lower left endpoint of the minimum rectangular box and the lower endpoint of the touch area is less than or equal to the distance between the lower right endpoint of the minimum rectangular box and the lower endpoint of the touch area, the lower left endpoint of the minimum rectangular box is determined as the first reference point, and the endpoint on the minimum rectangular box opposite to the first reference point is determined as the second reference point; if the distance between the lower left endpoint of the minimum rectangular box and the lower endpoint of the touch area is greater than the distance between the lower right endpoint of the minimum rectangular box and the lower endpoint of the touch area, the lower right endpoint of the minimum rectangular box is determined as the first reference point, and the endpoint on the minimum rectangular box opposite to the first reference point is determined as the second reference point.

[0082] In one embodiment of the present application, the coordinates of the lower left endpoint of the minimum rectangular frame are (the horizontal coordinate of the left endpoint, the vertical coordinate of the lower endpoint), and the coordinates of the lower right endpoint of the minimum rectangular frame are (the horizontal coordinate of the right endpoint, the vertical coordinate of the lower endpoint). The distances between the two endpoints below the minimum rectangular frame and the lower endpoint of the touch area can be calculated using the distance calculation formula between two points in the coordinate system.

[0083] For example, Figure 7 As shown, the distance between the endpoint A1 at the lower left of the minimum rectangular frame and the lower endpoint b0 of the touch area is smaller than the distance between the endpoint C1 at the lower right of the minimum rectangular frame and the lower endpoint b0 of the touch area. Therefore, the endpoint A1 at the lower left of the minimum rectangular frame is determined as the first reference point, and the endpoint B1 on the minimum rectangular frame opposite to the first reference point is determined as the second reference point.

[0084] S1023: Determine the vertical distance and horizontal distance between the two reference points.

[0085] In one embodiment of the present application, determining the vertical distance and the lateral distance between two reference points includes: determining the number of intersection areas between the sensing channels and the driving channels between the two reference points in a direction perpendicular to the lateral length of the touch panel as the vertical distance between the two reference points, and determining the number of intersection areas between the sensing channels and the driving channels between the two reference points in a direction parallel to the lateral length of the touch panel as the lateral distance between the two reference points.

[0086] See Figure 9 As shown, the two reference points are endpoints A1 and B1 of the rectangular frame X. The vertical distance between endpoints A1 and B1 is H, i.e., the longitudinal length of the rectangular frame X. The lateral distance between endpoints A1 and B1 is L, i.e., the lateral length of the rectangular frame X. The number of intersections between the sensing channels and the driving channels between endpoints A1 and B1 perpendicular to the lateral length of the touchpad is 4, so the vertical distance H between endpoints A1 and B1 is 4. The number of intersections between the sensing channels and the driving channels between endpoints A1 and B1 parallel to the lateral length of the touchpad is 5, so the lateral distance H between endpoints A1 and B1 is 5.

[0087] S1024: Calculate a current direction angle corresponding to the touch operation based on the vertical distance and the horizontal distance between the two reference points.

[0088] In one embodiment of the present application, calculating the current direction angle corresponding to the touch operation based on the vertical distance and the horizontal distance between the two reference points includes: calculating the current direction angle corresponding to the touch operation based on the vertical distance and the horizontal distance between the two reference points and the trigonometric function relationship.

[0089] Specifically, the relative position between the second reference point and the first reference point is determined. If the second reference point is to the right of the first reference point, the angle between the line connecting the two reference points and the horizontal side length of the minimum rectangular frame is calculated based on the vertical distance and the horizontal distance between the two reference points and the inverse tangent function, and the angle between the line connecting the two reference points and the horizontal side length of the minimum rectangular frame is determined as the current direction angle corresponding to the touch operation, that is, the current direction angle corresponding to the touch operation α=arctan(H / L); if the second reference point is to the left of the first reference point, the angle between the line connecting the two reference points and the horizontal side length of the minimum rectangular frame is calculated based on the vertical distance and the horizontal distance between the two reference points and the inverse tangent function, and the angle between the line connecting the two reference points and the horizontal side length of the minimum rectangular frame is added by 90 degrees as the current direction angle corresponding to the touch operation, that is, the current direction angle corresponding to the touch operation α=arctan(H / L)+90°; if the second reference point is directly above the first reference point, the current direction angle corresponding to the touch operation is determined to be 90 degrees. It can be understood that when the touch area corresponding to the touch operation is a line segment perpendicular to the horizontal edge of the touch panel, that is, when the touch area corresponding to the touch operation has only an upper endpoint and a lower endpoint, the second reference point is directly above the first reference point.

[0090] S103: Calculate a difference between the current direction angle and a historical direction angle corresponding to at least one historical touch operation to obtain at least a first direction angle difference.

[0091] In one embodiment of the present application, the historical touch operation and the current touch operation are continuous touch operations, and the continuous touch operation is the operation during which the user's hand continues to contact the touchpad. If the user's hand stops contacting the touchpad, the continuous touch operation is terminated. At this time, if the user's hand contacts the touchpad again to perform a touch operation, the touch operation before the touch operation cannot be used as a historical touch operation for the touch operation. The historical touch operation includes at least one continuous touch operation before the current touch operation. For example, if the sampling rate of the touch operation is 120Hz, the historical touch operation may include a touch operation 8ms before the current touch operation and a touch operation 16ms before the current touch operation. The historical direction angle corresponding to the historical touch operation is also calculated based on steps S1021-S1024. The current direction angle is subtracted from the historical direction angle corresponding to at least one historical touch operation to obtain the difference between the current direction angle and the at least one historical direction angle. The absolute value of the difference between the current direction angle and the at least one historical direction angle is determined as at least one first direction angle difference.

[0092] For example, the second reference point is to the right of the first reference point, the vertical distance between the two reference points is 4, and the horizontal distance is 5, then the current direction angle α0 = arctan (4 / 5) = 38.7°, the historical touch operation is 1, the historical direction angle α1 corresponding to the historical touch operation is 41.2°, and the difference between the current direction angle α0 and the historical direction angle α1 corresponding to the historical touch operation is -2.5°, then the first direction angle difference corresponding to the historical touch operation is 2.5°, that is, the first direction angle difference is 2.5°.

[0093] S104: If at least one first direction angle difference is less than or equal to a first threshold, executing a corresponding preset function based on the touch operation.

[0094] In one embodiment of the present application, at least one first direction angle difference is compared with a first threshold. If the at least one first direction angle difference is less than or equal to the first threshold, it indicates that the direction of the touch operation has not changed suddenly, the touch operation is not an accidental touch, and the corresponding function is executed based on the touch operation. Optionally, the first threshold is 5 degrees. In other embodiments, the first threshold can also be set to other values ​​as needed.

[0095] In one embodiment of the present application, executing a corresponding preset function based on a touch operation includes: the touch driver module determines the reporting point information generated by the touch operation based on the touch area, and executes the preset function corresponding to the touch operation based on the reporting point information. For example, the reporting point information is reported to the application layer, and the application controls the movement of the cursor of the electronic device based on the reporting point information. Specifically, the touch driver module determines the reporting point information generated by the touch operation based on the touch area, including: the touch driver module determines the center of gravity coordinates of the touch area based on the coordinates of multiple touch positions within the touch area using a center of gravity algorithm, and confirms the center of gravity coordinates of the touch area as the reporting point information generated by the touch operation.

[0096] See Figure 10 FIG. 1 is a flow chart of a touch detection method provided by another embodiment of the present application. The method is applied to an electronic device and includes:

[0097] S201 : In response to a touch operation performed by a user on a touch panel, a touch area generated by the touch operation on the touch panel is collected.

[0098] S202: Calculate a current direction angle corresponding to the touch operation based on the touch area.

[0099] S203 , calculating a difference between the current direction angle and a historical direction angle corresponding to at least one historical touch operation to obtain at least a first direction angle difference.

[0100] S204: If at least one first direction angle difference is less than or equal to a first threshold, execute a preset function corresponding to the touch operation.

[0101] S205: If at least one first direction angle difference is greater than a first threshold, the preset function corresponding to the touch operation is not executed.

[0102] For example, the first threshold is set to 5°, the second reference point is to the right of the first reference point, the vertical distance between the two reference points is 4, and the horizontal distance is 5, then the current direction angle α0 = arctan (4 / 5) = 38.7°, the historical touch operation is one, the historical direction angle α1 corresponding to the historical touch operation is 31.5°, the difference between the current direction angle α0 and the historical direction angle α1 corresponding to the historical touch operation is 7.2°, then the direction angle difference corresponding to the historical touch operation is 7.2°, that is, the first direction angle difference is 7.2°, which is greater than the first threshold, indicating that the direction of the touch operation has suddenly changed, and the current touch operation is determined to be a false touch. The preset function corresponding to the touch operation is not executed to prevent false touch.

[0103] The specific implementation of steps S201-S204 is the same as that of steps S101-S104, and will not be repeated here.

[0104] See Figure 11 FIG. 1 is a flow chart of a touch detection method provided by another embodiment of the present application. The method is applied to an electronic device and includes:

[0105] S301 : In response to a touch operation performed by a user on a touch panel, a touch area generated by the touch operation on the touch panel is collected.

[0106] S302: Calculate a current direction angle corresponding to the touch operation based on the touch area.

[0107] S303: If there is only one touch area, calculate the difference between the current direction angle and the historical direction angle corresponding to at least one historical touch operation to obtain at least a first direction angle difference.

[0108] In another embodiment of the present application, it is determined whether there are multiple touch areas. If there are not multiple touch areas, that is, there is only one touch area, the same method as steps S1021-S1024 is used to calculate a current direction angle corresponding to the touch operation.

[0109] S304: If at least one first direction angle difference is less than or equal to a first threshold, execute a preset function corresponding to the touch operation.

[0110] S305: If at least one first direction angle difference is greater than a first threshold, the preset function corresponding to the touch operation is not executed.

[0111] S306 : If there are multiple touch areas, calculate the difference between every two current direction angles to obtain at least one second direction angle difference.

[0112] In another embodiment of the present application, if there are multiple touch areas, in step S302, the same method as steps S1021-S1024 can be used to calculate multiple current direction angles corresponding to the touch operation based on each touch area, and the multiple current direction angles are subtracted from each other, and the absolute value of the difference after subtraction is determined to obtain at least one second direction angle difference.

[0113] See Figure 12 As shown, for example, there are 2 touch areas, in the minimum rectangular frame X corresponding to the first touch area, the second reference point is on the right side of the first reference point, the vertical distance between the two reference points is 4, and the lateral distance is 5, then the first current direction angle α0 = arctan (4 / 5) = 38.7°, in the minimum rectangular frame Y corresponding to the second touch area, the second reference point is on the left side of the first reference point, the vertical distance between the two reference points is 5, and the lateral distance is 4, then the second current direction angle α0 = arctan (5 / 4) + 90° = 141.3°, the difference between the first current direction angle and the second direction angle is -102.6°, then the second direction angle difference is 102.6°.

[0114] S307: If at least one second direction angle difference is less than or equal to a second threshold, execute a preset function corresponding to the touch operation.

[0115] In another embodiment of the present application, at least one second direction angle difference is compared with a second threshold to determine whether the at least one second direction angle difference is less than or equal to the second threshold. If the at least one second direction angle difference is less than or equal to the second threshold, it indicates that the multiple touch directions are consistent, the touch operation is not an accidental touch, and the preset function corresponding to the touch operation is executed. Optionally, the second threshold is 10 degrees. In other embodiments, the second threshold can also be set to other values ​​as needed.

[0116] In another embodiment of the present application, executing a corresponding preset function based on a touch operation includes: a touch driving module determines the reporting point information generated by the touch operation based on multiple touch areas, and reports the reporting point information to the application layer, and controls the electronic device to execute the preset function based on the reporting point information through the application.

[0117] S308: If any second direction angle difference is greater than a second threshold, the preset function corresponding to the touch operation is not executed.

[0118] According to the above example, when the number of touch areas is 2, a second direction angle difference is 102.6°, which is greater than the second threshold value of 10°. Therefore, it means that the touch directions of multiple fingers are inconsistent, and the current touch operation is determined to be a false touch, and the preset function corresponding to the touch operation is not executed.

[0119] See Figure 13 FIG2 is a schematic diagram of a touch panel module according to an embodiment of the present invention. The touch panel 196 includes, but is not limited to, a touch detection module 205, an algorithm execution module 206, a power supply module 207, a storage module 208, a logic control module 209, a touch panel driver module 210, and a key response module 211.

[0120] In one embodiment of the present application, the touch detection module 205 is used to detect finger touch information. The touch detection module 205 can be a capacitance detection chip, which can include the above-mentioned sensing layer. The algorithm running module 206 is used to run the entire algorithm processing flow, for example Figure 3 、 4 , 8, 10, 11, 15-17. The power module 206 is used to manage the power supply of the touchpad and switch between working and sleeping modes. The storage module 208 is used to store code programs, data and other related information. The logic control module 209 is used to control the working mode of the touchpad and the communication process with the electronic device (laptop or tablet). The working mode of the touchpad may include turning on and off. The touchpad driver module 210 is used to drive the touchpad 196, and the key response module 211 is used to detect the user's key operation on the touchpad 196.

[0121] Touchpads support single-touch and multi-finger gestures. With single-touch gestures, the user's finger direction doesn't change suddenly. With multi-finger gestures, the directions of all fingers are typically consistent. Based on this, the touchpad uses capacitive sensing to obtain information about the finger's touch frame and calculates the finger frame's orientation angle α. This consistent orientation angle prevents accidental touches.

[0122] See Figure 14A As shown in the figure, taking a single-point operation as an example, a user's single finger touches the touchpad and slides to the lower right. The difference between the direction angles corresponding to the two adjacent touch operations is small. Therefore, by calculating the difference between the direction angles corresponding to the two adjacent touch operations, it can be determined whether the touch operation is an accidental operation, thereby realizing the touchpad's anti-accidental touch protection. Figure 14B As shown, taking the case of two fingers performing a touch operation at the same time as an example, according to the user's usage habits, when two fingers perform a touch operation at the same time, the difference between the direction angles corresponding to the touch operations generated by different fingers is small. Therefore, by calculating the difference between the direction angles corresponding to different touch operations, it is possible to determine whether the touch operation is an erroneous operation, thereby realizing the prevention of false touches on the touchpad.

[0123] In one embodiment of the present application, the principle of detecting a single finger frame to prevent accidental touches is as follows: When a user operates a single finger on the touchpad, the finger does not suddenly change direction due to the continuity and continuity of human operation. When the touchpad detects a finger frame, the frame's direction angle α is compared with the direction of the historical frame (the previous frame or frames). If the direction difference is greater than a certain threshold, it is considered abnormal and the point notification is suppressed, thus preventing accidental touch notifications.

[0124] See Figure 15 FIG. 1 is a flowchart of a process for detecting a single finger frame and preventing accidental touches according to an embodiment of the present application, specifically including:

[0125] S401: A single finger frame is detected, where the finger frame is a type of touch area mentioned above.

[0126] S402: Calculate the frame direction angle α, where the frame direction angle is the direction angle of the finger touch operation.

[0127] S403: Calculate the historical frame direction angle α', where the historical frame direction angle is the direction angle of the historical finger touch operation.

[0128] At step S404, it is determined whether the difference between the frame orientation angle α and the historical frame orientation angle α' is greater than a first threshold. If the difference between the frame orientation angle α and the historical frame orientation angle α' is greater than the first threshold, the process proceeds to step S405. If the difference between the frame orientation angle α and the historical frame orientation angle α' is less than or equal to the first threshold, the process proceeds to step S406.

[0129] S405, suppressing the current finger frame from reporting the point.

[0130] S406: Do not suppress the current finger frame reporting point.

[0131] In one embodiment of the present application, the principle of detecting a multi-finger frame to prevent accidental touches is as follows: the touchpad supports multi-finger same-direction operations, such as two-finger swipe up, swipe down to turn pages, three-finger swipe down to return to the desktop, etc. For this multi-finger operation function, the directions of the multiple fingers are consistent, and there is no scenario where the directions of the fingers are greatly different. When the touchpad detects a multi-finger frame, the direction angles α1, α2, ..., α of each finger frame are calculated. i The direction angles of each two finger frames are compared and judged. If they are in different directions (the direction difference is greater than a certain threshold), it is considered abnormal and the reporting point is suppressed.

[0132] See Figure 16 FIG. 1 is a flowchart of a process for detecting a multi-finger frame and preventing accidental touches according to an embodiment of the present application, specifically including:

[0133] S501: Detect a multi-finger frame.

[0134] S502, calculate the direction angles α1, α2, ..., α of each frame i .

[0135] S503: Compare the direction angles of each frame pairwise.

[0136] S504: Determine whether the difference between the orientation angles of any two boxes is greater than a second threshold. If the difference between the orientation angles of any two boxes is greater than the second threshold, the process proceeds to S505; if the difference between the orientation angles of any two boxes is greater than the second threshold, the process proceeds to S506.

[0137] S505: Suppress the current finger frame from reporting points.

[0138] S506: Do not suppress the current finger frame reporting point.

[0139] In one embodiment of the present application, a method for calculating the orientation angle of a finger frame is as follows: the orientation angle of the frame is calculated using the relative position A of the finger frame's boundary, the distance between point B, and trigonometric functions. Specifically, the touchpad detects the frame information, counts the intersection of the four boundaries of the frame, and the position information of the upper, lower, left, and right boundaries with the four borders; finds the bottommost point A and point B on the diagonal line, with the vertical distance between point B and point A recorded as H and the horizontal distance recorded as L; when point B is to the right of point A, the orientation angle α = arctan(H / L); otherwise, when point B is to the left of point A, the orientation angle α = arctan(H / L) + 90°; when point B is directly above point A, the orientation angle α is 90°.

[0140] See Figure 17 FIG. 1 is a flow chart of a method for calculating a finger frame direction angle according to an embodiment of the present application, which specifically includes:

[0141] S601: Detect a finger frame.

[0142] S602: Count the boundaries of the box, i.e., the top, bottom, left, and right boundary positions. The top, bottom, left, and right boundary positions are the upper endpoint, lower endpoint, left endpoint, and right endpoint of the above text, respectively.

[0143] S603, counting the intersection points of the four bounding boxes.

[0144] S604, determining the bottom point A and the diagonal point B.

[0145] S605: Determine whether point B is on the right side of point A. If point B is on the right side of point A, the process proceeds to S606; if point B is not on the right side of point A, the process proceeds to S607.

[0146] S606, calculating the frame direction angle α=arctan(H / L).

[0147] S607, calculate the frame direction angle α = arctan (H / L) + 90. Then the direction angle calculation ends.

[0148] The embodiment of the present application utilizes the characteristics that the direction of the touchpad will not change suddenly when the user performs a single-point operation; the direction is consistent when performing a multi-finger gesture operation, and utilizes the directionality of the finger frame on the touchpad to optimize the problem of false touches and improve the user experience of the touchpad.
