[0029] The embodiments of the present application provide a tactile feedback method, apparatus, terminal device and storage medium for timely responding to a user's pressing operation on a side button, providing tactile feedback and reducing the probability of erroneous operation.

[0030] In order to make the technical personnel in the technical field better understand the scheme of the present application, the technical scheme in the embodiment of the present application will be described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, not all of the embodiments. Based on the embodiments in the present application, they should all fall within the scope of protection of the present application.

[0031] The side buttons on current terminal devices (such as mobile phones) have the disadvantage of single function and users cannot customize the side button functions according to different application scenarios; moreover, after users operate the side buttons, they cannot obtain timely and realistic tactile feedback, which increases the probability of misoperation.

[0032] In the embodiment of the present application, the terminal device can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self driving, a wireless terminal device in remote medical, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, or a wireless terminal device in a smart home, etc.

[0033] As an example but not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable devices may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also powerful functions achieved through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-sized, and fully or partially independent of smartphones, such as smart watches or smart glasses, as well as devices that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various types of smart bracelets and smart jewelry for vital sign monitoring.

[0034] The technical solution of the present application is further described below by way of embodiments. Figure 1 As shown, it is a schematic diagram of an embodiment of a tactile feedback method in an embodiment of the present application, which may include:

[0035] 101. In response to a user pressing a side button of a terminal device, generate pressing data.

[0036] Optionally, the pressing data includes at least one of pressing intensity, pressing times and pressing duration.

[0037] Optionally, the generating of pressing data in response to the user pressing the side button may include: generating pressing data in response to the user pressing the side button through a pressure sensor; or generating pressing data in response to the user pressing the side button through a piezoelectric ceramic device.

[0038] 102. Determine a current vibration waveform corresponding to a current application scenario of the terminal device and the pressure data, where different application scenarios and different pressure data correspond to different vibration waveforms.

[0039] Optionally, the terminal device may detect a current application scenario, which may be a scenario corresponding to an application program currently running in the foreground of the terminal device.

[0040] Exemplarily, the current application scenario may include but is not limited to a camera scenario and a game scenario.

[0041] Optionally, determining a current vibration waveform corresponding to the current application scenario of the terminal device and the pressing data may include but is not limited to the following implementations:

[0042] (1) selecting a current vibration waveform mapping table corresponding to a current application scenario of a terminal device from a first preset vibration waveform database, wherein the first preset vibration waveform database includes vibration waveform mapping tables corresponding to different application scenarios, and each vibration waveform mapping table includes a mapping relationship between different pressure data and different vibration waveforms; and determining a corresponding current vibration waveform in the current vibration waveform mapping table according to the current pressure data.

[0043] (2) Selecting the current vibration waveform corresponding to the current application scenario of the terminal device from the second preset vibration waveform database, wherein the second preset vibration waveform database includes vibration waveforms corresponding to the reference pressing data range under different application scenarios; obtaining the current vibration waveform according to the current pressing data and the reference pressing data range, and the vibration waveform corresponding to the reference pressing data. It is understandable that, according to whether the current pressing data is within the pressing data reference range, it is determined whether to adjust the vibration waveform corresponding to the reference pressing data range, and finally the current vibration waveform is obtained.

[0044] Optionally, if the current press data is within the reference press data range, the vibration waveform corresponding to the reference press data range is used as the current vibration waveform corresponding to the current press data; if the current press data is lower than the lower limit of the reference press data range, the amplitude of the vibration waveform corresponding to the reference press data range can be reduced to reduce the vibration provided by the tactile feedback, and the current vibration waveform corresponding to the current press data is obtained; if the current press data is lower than the upper limit of the reference press data range, the amplitude of the vibration waveform corresponding to the reference press data range can be increased to increase the vibration provided by the tactile feedback, and the current vibration waveform corresponding to the current press data is obtained.

[0045] Optionally, the first preset vibration waveform database and the second preset vibration waveform database are vibration waveform databases saved before the terminal device leaves the factory.

[0046] It is understandable that for the simulated side buttons in different application scenarios, the vibration waveform of the tactile feedback can be customized before the terminal device leaves the factory. Before leaving the factory, the terminal equipment manufacturer collects the simulation effects of different physical side buttons in various application scenarios, including but not limited to the vibration waveform of the tactile feedback of the physical side buttons, such as the amplitude, frequency, feedback duration and other factors of the vibration waveform; then optimizes and debugs according to the specific hardware solution of this terminal device, so that the vibration waveform finally felt by the user has the same or similar characteristics as the tactile feedback effect of the physical side button that the manufacturer hopes to simulate, and stores these vibration waveforms in the vibration waveform database as a preset vibration waveform database, and binds them to the corresponding application scenarios. After leaving the factory, when the user chooses to turn on the smart side button and selects the side button function mapping for a certain application scenario, the corresponding vibration waveform is searched through the preset vibration waveform database, and then played according to the vibration waveform to achieve the effect of simulating the corresponding side button touch.

[0047] 103. Perform tactile feedback on the pressing operation according to the current vibration waveform.

[0048] Optionally, when a pressure sensor is used to generate pressing data in response to a user pressing a side button, providing tactile feedback for the pressing operation based on a current vibration waveform may include: providing tactile feedback for the pressing operation based on the current vibration waveform through a linear vibration motor or an electromagnetic coil.

[0049] Optionally, when a piezoelectric ceramic device is used to generate pressing data in response to a user pressing a side button, providing tactile feedback for the pressing operation based on a current vibration waveform may include: providing tactile feedback for the pressing operation based on the current vibration waveform through the piezoelectric ceramic device.

[0050] It is understandable that in the hardware implementation of the side button, different vibration waveforms can be used to autonomously call for tactile feedback of the pressing operation, which may include but are not limited to the following solutions:

[0051] (1) A pressure sensor is used to collect the pressure applied to the side buttons by the user, and a linear resonant actuator (LRA) is used to provide tactile feedback vibration.

[0052] (2) Piezoelectric ceramic devices are used to simultaneously collect the user's pressing force on the side buttons and provide tactile feedback vibration.

[0053] (3) A pressure sensor is used to collect the pressure applied by the user to the side buttons, and a customized electromagnetic coil is used to provide tactile feedback vibration.

[0054] Optionally, the implementation principle of the pressure sensor includes, but is not limited to: resistive, capacitive, piezoelectric, ultrasonic and other implementation methods.

[0055] The common feature of the above-mentioned implementation methods is that the user's pressing force on the side buttons can be collected, so as to set different vibration waveforms according to the comparison between the pressing force and different thresholds. Optionally, the vibration waveform for tactile feedback can also be customized according to the application scenario and other factors, so as to achieve the refinement and simulation of tactile feedback and realize the diversification of button functions. For example: the user's pressing time on the side buttons can also be collected, and different vibration waveforms can be set by comparing with the time threshold; the number of presses can also be collected, combined with the pressing force, and / or the pressing time, to set different vibration waveforms.

[0056] The vibration waveform is triggered by the user's pressing operation on the side button. As long as the pressing force corresponding to the pressing operation can match any of the preset multiple pressure thresholds, it will match the vibration waveform corresponding to the preset vibration waveform database to provide a tactile feedback to the user at the side button. When the pressing force matches different pressure thresholds, the feedback strength of the vibration waveform is different, allowing the user to perceive their pressing force through tactile feedback.

[0057] Optionally, the pressing data includes the pressing force; and the performing tactile feedback on the pressing operation according to the current vibration waveform may include but is not limited to the following implementations:

[0058] (1) When the pressing force is less than a first threshold, tactile feedback is provided to the pressing operation according to a first vibration waveform; that is, the first vibration waveform is output so that the user can feel the vibration corresponding to the first vibration waveform.

[0059] (2) When the pressing force is greater than or equal to the first threshold and less than a second threshold, tactile feedback is provided to the pressing operation according to the second vibration waveform; that is, the second vibration waveform is output so that the user can feel the vibration corresponding to the second vibration waveform.

[0060] (3) when the pressing force is greater than or equal to the second threshold, performing tactile feedback on the pressing operation according to the third vibration waveform; that is, outputting the third vibration waveform so that the user can feel the vibration corresponding to the third vibration waveform;

[0061] Among them, the amplitude of the first vibration waveform is smaller than the amplitude of the second vibration waveform, and the amplitude of the second vibration waveform is smaller than the amplitude of the third vibration waveform. Therefore, the vibration corresponding to the first vibration waveform perceived by the user (also called light touch vibration) is smaller than the vibration corresponding to the second vibration waveform (also called light pressure vibration), and the vibration corresponding to the second vibration waveform perceived by the user is smaller than the vibration corresponding to the third vibration waveform (also called heavy pressure vibration).

[0062] Optionally, the pressing data includes the pressing force and the pressing duration; and the performing of tactile feedback on the pressing operation according to the current vibration waveform may include but is not limited to the following implementations:

[0063] (1) When the pressing force is less than the first threshold and the pressing duration is less than the duration threshold, tactile feedback is provided to the pressing operation according to the first vibration waveform; that is, the first vibration waveform is output so that the user can feel the vibration corresponding to the first vibration waveform.

[0064] (2) When the pressing force is greater than or equal to the first threshold and less than the second threshold, and the pressing duration is greater than the duration threshold, tactile feedback is provided for the pressing operation according to the second vibration waveform; that is, the second vibration waveform is output so that the user can feel the vibration corresponding to the second vibration waveform.

[0065] (3) when the pressing force is greater than or equal to the second threshold and the pressing duration is greater than the duration threshold, performing tactile feedback on the pressing operation according to the third vibration waveform; that is, outputting the third vibration waveform so that the user can feel the vibration corresponding to the third vibration waveform;

[0066] Among them, the amplitude of the first vibration waveform is smaller than the amplitude of the second vibration waveform, and the amplitude of the second vibration waveform is smaller than the amplitude of the third vibration waveform. Therefore, the vibration corresponding to the first vibration waveform perceived by the user (also called light touch vibration) is smaller than the vibration corresponding to the second vibration waveform (also called light pressure vibration), and the vibration corresponding to the second vibration waveform perceived by the user is smaller than the vibration corresponding to the third vibration waveform (also called heavy pressure vibration).

[0067] Optionally, the pressing data includes the pressing force and the number of pressing times; and the performing tactile feedback on the pressing operation according to the current vibration waveform may include but is not limited to the following implementations:

[0068] (1) When the pressing force is less than a first threshold, tactile feedback is provided for the pressing operation according to the first vibration waveform and the number of pressing times; if the number of pressing times is once, the first vibration waveform is output once; if the number of pressing times is twice, the first vibration waveform is output twice, and so on, the first vibration waveform is output, so that the user can feel the vibration corresponding to the first vibration waveform.

[0069] (2) When the pressing force is greater than or equal to the first threshold and less than the second threshold, tactile feedback is provided for the pressing operation according to the second vibration waveform and the number of pressing times; if the number of pressing times is once, the second vibration waveform is output once; if the number of pressing times is twice, the second vibration waveform is output twice, and so on, the second vibration waveform is output, so that the user can feel the vibration corresponding to the second vibration waveform.

[0070] (3) when the pressing force is greater than or equal to the second threshold, performing tactile feedback on the pressing operation according to the third vibration waveform and the number of pressings; if the number of pressings is once, outputting the third vibration waveform once; if the number of pressings is twice, outputting the third vibration waveform twice, and so on, outputting the third vibration waveform, so that the user can feel the vibration corresponding to the third vibration waveform;

[0071] Among them, the amplitude of the first vibration waveform is smaller than the amplitude of the second vibration waveform, and the amplitude of the second vibration waveform is smaller than the amplitude of the third vibration waveform. Therefore, the vibration corresponding to the first vibration waveform perceived by the user (also called light touch vibration) is smaller than the vibration corresponding to the second vibration waveform (also called light pressure vibration), and the vibration corresponding to the second vibration waveform perceived by the user is smaller than the vibration corresponding to the third vibration waveform (also called heavy pressure vibration).

[0072] Optionally, the pressing data includes the pressing force, pressing duration, and number of pressing times; and the performing of tactile feedback on the pressing operation according to the current vibration waveform may include but is not limited to the following implementations:

[0073] (1) When the pressing force is less than the first threshold and the pressing duration is less than the duration threshold, tactile feedback is provided for the pressing operation according to the first vibration waveform and the number of pressing times; if the number of pressing times is once, the first vibration waveform is output once; if the number of pressing times is twice, the first vibration waveform is output twice, and so on, the first vibration waveform is output, so that the user can feel the vibration corresponding to the first vibration waveform.

[0074] (2) When the pressing force is greater than or equal to the first threshold and less than the second threshold, and the pressing duration is greater than the duration threshold, tactile feedback is provided for the pressing operation according to the second vibration waveform and the number of presses; if the number of presses is once, the second vibration waveform is output once; if the number of presses is twice, the second vibration waveform is output twice, and so on, the second vibration waveform is output, so that the user can feel the vibration corresponding to the second vibration waveform.

[0075] (3) when the pressing force is greater than or equal to the second threshold value, and the pressing duration is greater than the duration threshold value, performing tactile feedback on the pressing operation according to the third vibration waveform and the number of pressing times; if the number of pressing times is once, outputting the third vibration waveform once; if the number of pressing times is twice, outputting the third vibration waveform twice, and so on, outputting the third vibration waveform, so that the user can feel the vibration corresponding to the third vibration waveform;

[0076] Among them, the amplitude of the first vibration waveform is smaller than the amplitude of the second vibration waveform, and the amplitude of the second vibration waveform is smaller than the amplitude of the third vibration waveform. Therefore, the vibration corresponding to the first vibration waveform perceived by the user (also called light touch vibration) is smaller than the vibration corresponding to the second vibration waveform (also called light pressure vibration), and the vibration corresponding to the second vibration waveform perceived by the user is smaller than the vibration corresponding to the third vibration waveform (also called heavy pressure vibration).

[0077] In the embodiment of the present application, in response to the user's pressing operation on the side button of the terminal device, press data is generated; the current vibration waveform corresponding to the current application scenario of the terminal device and the press data is determined, and different application scenarios and different press data correspond to different vibration waveforms; tactile feedback is given to the press operation according to the current vibration waveform. It is used to timely respond to the user's pressing operation on the side button, generate press data, and give tactile feedback to the press operation according to the current application scenario and press data of the terminal device, so as to reduce the probability of misoperation.

[0078] like Figure 2 As shown, it is a schematic diagram of another embodiment of the tactile feedback method in the embodiment of the present application, which may include:

[0079] 201. In response to a user's setting operation on a side button function in a target application scenario, the side button function is set to a function corresponding to the target application scenario.

[0080] Optionally, the target application scenario is a camera scene, and the side button function is a function corresponding to the camera scene; the target application scenario is a game scene, and the side button function is a function corresponding to the game scene.

[0081] For example, Figure 3A As shown in FIG. 1 , a schematic diagram of the smart side button setting interface in an embodiment of the present application is shown. Figure 3B , which is a schematic diagram of a user's operation of setting the side button function in a target application scenario in an embodiment of the present application. Figure 3A As shown in the figure, in the smart side button setting interface, the function menu corresponding to the volume up button, volume down button, and power button can be expanded in response to the user's opening operation. Figure 3B As shown, users can set the functions of the volume up key, volume down key, and power key according to their actual needs.

[0082] For the volume up key, the general function is to increase the volume; in the camera scene, the corresponding functions include: enlarged preview, increase brightness, increase saturation, increase color temperature, increase hue, and other custom functions; in the game scene, such as Peace Elite scene, the corresponding functions include scope magnification +, other custom touch screen area functions, etc.; in the game scene, such as King of Glory scene, the corresponding functions include the first trick, other custom touch screen area functions, etc.

[0083] For the volume down button, the general function is to reduce the volume; in the camera scene, the corresponding functions include: reducing the preview, reducing the brightness, reducing the saturation, reducing the color temperature, reducing the hue, and other custom functions; in the game scene, such as the Peace Elite scene, the corresponding functions include the scope magnification, other custom touch screen area functions, etc.; in the game scene, such as the King of Glory scene, the corresponding functions include the second trick, other custom touch screen area functions, etc.

[0084] For the power button, the function is the power button; in the camera scene, the corresponding functions are: shutter button (half press to focus / long press to take a photo), start and stop recording, switch between front and rear cameras, switch between standard / professional mode; in the game scene, such as Peace Elite scene, the corresponding functions include shooting, other functions of the custom touch screen area, etc.; in the game scene, such as King of Glory scene, the corresponding functions include big moves, other functions of the custom touch screen area, etc.

[0085] It should be noted that the functions set by the user for the volume up key, volume down key and power key are corresponding. For example, in the camera scene, the function set for the volume up key is to enlarge the preview, and the function set for the volume down key is to reduce the preview.

[0086] 202. In response to a user pressing a side button of a terminal device, generate pressing data.

[0087] 203 . Determine a current vibration waveform corresponding to a current application scenario of the terminal device and the pressure data, where different application scenarios and different pressure data correspond to different vibration waveforms.

[0088] 204. Perform tactile feedback on the pressing operation according to the current vibration waveform.

[0089] It should be noted that the description of steps 202-204 can be referred to Figure 1 101-103 in the illustrated embodiment will not be described in detail here.

[0090] 205. Respond to the user's pressing operation on the side button and execute a corresponding function.

[0091] Optionally, the method may further include: when the current application scenario includes at least two application scenarios, determining, through a preset side button function priority mapping table, that the side button function is the side button function corresponding to the first application scenario, and the first application scenario is the application scenario with the highest priority among the at least two application scenarios.

[0092] Optionally, selecting the current vibration waveform mapping table corresponding to the current application scenario from a preset vibration waveform database may include: selecting a first vibration waveform mapping table corresponding to the first application scenario from a preset vibration waveform database.

[0093] Optionally, the preset side button function priority mapping table is prioritized according to user habits, convenience of user operation, or order of higher importance.

[0094] It is understandable that, considering the conflicts in the side button functions in some application scenarios, such as the scenario where an incoming call occurs when the user is using the camera, the volume button function needs to be restored to the volume adjustment function, rather than continuing to be mapped to the function corresponding to the camera application scenario. Therefore, it is necessary to formulate a side button function priority mapping table. For each concurrent application scenario, sort them in the order of user habits / convenience for user operation / higher importance, and map and output the side button functions accordingly. As in the above example, when the incoming call pop-up window floats above the camera application interface, the mobile phone system uses the application stack list to determine the application that is focused by the user and is floating on other applications. At this time, the volume button function needs to be restored to the volume adjustment function.

[0095] Optionally, the side button includes a volume up button, a volume down button, or a power button. When the current application scenario includes a camera scenario, responding to a user pressing the side button to execute a corresponding function may include:

[0096] In response to the user pressing the volume up key, executing a corresponding zoom preview function, brightness increase function, saturation increase function, color temperature increase function, or hue increase function; or,

[0097] In response to the user pressing the volume down key, executing a corresponding zoom out preview function, brightness reduction function, saturation reduction function, color temperature reduction function, or hue reduction function; or,

[0098] In response to the user pressing the power button, the corresponding focus function, photo taking function, start / stop video recording function, front and rear lens switching function, or photo mode switching function is executed.

[0099] Optionally, the side button includes a volume up button, a volume down button, or a power button. When the current application scenario includes a game scenario, responding to the user's pressing operation on the side button to execute a corresponding function may include:

[0100] In response to the user pressing the volume up key, executing the corresponding first trick function, or increasing the magnification of the scope; or,

[0101] In response to the user pressing the volume down button, executing the corresponding second trick function, or reducing the magnification of the scope; or,

[0102] In response to the user pressing the power button, a corresponding ultimate function or a shooting function is executed.

[0103] Optionally, assuming that in response to the user pressing the volume up key, a corresponding zoom preview function is executed, the current vibration waveform changes from the first vibration waveform to the second vibration waveform to the third vibration waveform, and the zoom preview coefficient in the zoom preview operation command becomes larger and larger.

[0104] Assume that in response to the user pressing the volume up key, the corresponding brightness increase function is executed, the current vibration waveform changes from the first vibration waveform to the second vibration waveform to the third vibration waveform, and the brightness increase coefficient in the brightness increase operation command becomes larger and larger.

[0105] Assume that in response to the user pressing the volume up key, the corresponding saturation increase function is executed, the current vibration waveform changes from the first vibration waveform to the second vibration waveform to the third vibration waveform, and the saturation increase coefficient in the saturation increase operation command becomes larger and larger.

[0106] Assume that in response to the user pressing the volume up key, the corresponding color temperature increase function is executed, the current vibration waveform changes from the first vibration waveform to the second vibration waveform to the third vibration waveform, and the color temperature increase coefficient in the color temperature increase operation command becomes larger and larger.

[0107] Assume that in response to the user pressing the volume up key, the corresponding tone increase function is executed, the current vibration waveform changes from the first vibration waveform to the second vibration waveform to the third vibration waveform, and the tone increase coefficient in the tone increase operation command becomes larger and larger.

[0108] Assume that in response to the user pressing the volume down key, the corresponding zoom-out preview function is executed, the current vibration waveform changes from the first vibration waveform to the second vibration waveform to the third vibration waveform, and the zoom-out preview coefficient in the zoom-out preview operation command becomes larger and larger.

[0109] Assume that in response to the user pressing the volume down key, the corresponding brightness reduction function is executed, the current vibration waveform changes from the first vibration waveform to the second vibration waveform to the third vibration waveform, and the brightness reduction coefficient in the brightness reduction operation command becomes larger and larger.

[0110] Assume that in response to the user pressing the volume down key, the corresponding saturation reduction function is executed, the current vibration waveform changes from the first vibration waveform to the second vibration waveform to the third vibration waveform, and the saturation reduction coefficient in the saturation reduction operation command becomes larger and larger.

[0111] Assume that in response to the user pressing the volume down key, the corresponding color temperature reduction function is executed, the current vibration waveform changes from the first vibration waveform to the second vibration waveform to the third vibration waveform, and the color temperature reduction coefficient in the color temperature reduction operation command becomes larger and larger.

[0112] Assume that in response to the user pressing the volume down key, the corresponding tone reduction function is executed, and the current vibration waveform changes from the first vibration waveform to the second vibration waveform to the third vibration waveform, and the tone reduction coefficient in the tone reduction operation command becomes larger and larger.

[0113] It should be noted that the timing of steps 202 - 204 and the timing of step 205 are not limited.

[0114] The current side buttons mainly include up and down volume buttons and a power button, which can only realize the functions of volume increase and decrease and screen on / off when pressed. In this application, users can customize the functions of the side buttons in a specific application scenario through the user interface (UI) provided by the terminal device system, and bind the side buttons with the customized functions, so as to realize the functional differences of the side buttons in different application scenarios; because the hardware solution uses a pressure sensor, it can subdivide events such as light touch / light pressure / heavy pressure / double click according to the scene, thereby triggering different side button functions.

[0115] For example: in the photo application scenario, the functions corresponding to these three buttons cannot provide any useful help for the camera scenario; in this application, users can customize the up and down volume buttons through the UI interface to simulate the zoom button function of the camera to zoom in / out; the power button simulates the shutter button of the camera to achieve the functions of half-pressing to focus and full-pressing to take pictures. For example: in the scenario where the mobile phone is running a game, the up and down volume buttons and the power button can also be mapped to game function buttons at different positions on the screen to achieve the function of quickly triggering in-game moves / events.

[0154] The memory 620 can be used to store software programs and modules.

Optionally, the touch panel 631 may include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into contact coordinates, and then sends it to the processor 680, and can receive and execute commands sent by the processor 680.
