[0002] Currently, for large-size intelligent interactive tablets (for example, intelligent interactive tablets with a size of more than 40 inches), the adjustment of machine core parameters (such as brightness, volume, power on / off, etc.) is mainly carried out in two ways: The first is the hardware method, where multiple mechanical physical buttons are set on the surface of the machine shell for individual adjustment. This method of setting multiple mechanical physical buttons on the surface of the machine shell weakens the overall appearance of the machine and reduces the overall dust and water resistance performance of the machine; and for parameters that need to be continuously adjusted, the adjustment efficiency of the mechanical physical button method is relatively low. The second is the software method, where multiple-level menus are set for step-by-step adjustment in multiple modes. This method of using step-by-step adjustment menus results in a long interaction chain, reducing the efficiency of interaction operations and affecting the interaction experience; and the lack of tactile feedback in existing virtual buttons on the touch screen leads to problems such as accidental triggering. Summary of the Invention

[0025] For the convenience of understanding the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is expressed as "fixed to" another element, it can be directly on the other element, or there can be one or more intermediate elements therebetween.

In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0026] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not used to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0027] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] Currently, for large-size intelligent interaction flat panels (for example, intelligent interaction flat panels over 40 inches), the adjustment of machine core parameters (such as brightness, volume, power on / off, etc.) is mainly through two methods: The first is the hardware method, where multiple mechanical physical buttons are set on the surface of the machine shell for individual adjustment one by one. The second is the software method, where multiple-level menus are set for step-by-step adjustment of multiple modes.

[0029] For the first hardware method, although specific parameters can be adjusted intuitively and conveniently, since multiple mechanical physical buttons are set on the surface of the machine shell, the integrity of the machine appearance is weakened, and the overall dustproof and waterproof performance of the machine is also reduced; and for parameters that need to be continuously adjusted, such as volume and brightness, the adjustment efficiency of the mechanical physical button method is relatively low; and the physical mechanical buttons also have the defect that they cannot be redefined.

[0030] For the second software method, although it solves the defect that physical mechanical buttons cannot be redefined, the step-by-step adjustment menu makes the interaction chain longer, reducing the efficiency of interaction operations and affecting the interaction experience. For example, taking volume adjustment as an example, the user needs to perform the following steps to complete the volume adjustment to level seven: First step, the user needs to click on the identification arrow on the surface of the machine shell to bring up the software menu interface; Second step, find the volume adjustment icon from the icons in the brought-up software menu interface to bring up the volume adjustment interface; Third step, adjust the volume on the slider in the volume adjustment interface. That is, the user needs three operations through the software menu and needs to find the volume adjustment icon among multiple icons on the software menu interface to reach the volume adjustment interface. Moreover, in the software method, if the buttons on the machine (such as the power button) are also set as virtual buttons in the software method, although the definability of the buttons is improved, due to the lack of tactile feedback similar to physical mechanical buttons in the virtual buttons on the touch screen, problems such as accidental triggering are caused.

[0031] Therefore, in view of the above technical problems found in the research and development process, the embodiment of the present application provides a virtual button interaction method for an intelligent interaction tablet. By setting a virtual button area in the intelligent interaction tablet and obtaining the pressing force applied to the virtual button area when the virtual button area is touched, the whole intelligent interaction tablet has no mechanical physical buttons, optimizing the appearance of the intelligent interaction tablet, increasing the overall appearance integrity of the intelligent interaction tablet, and improving the overall dustproof and waterproof performance of the intelligent interaction tablet; By judging rules according to the pressing force and preset touch gestures, it can accurately identify various different touch gesture operations including double-click, single-click, slide, or heavy press, etc. performed by the user in the virtual button area of the intelligent interaction tablet, making the function operations used frequently more intuitive and efficient, and realizing the adjustment of the parameters of the intelligent interaction tablet more conveniently, intuitively, and efficiently; By generating vibrations according to the touch gesture operations and providing tactile feedback matching the touch gesture operations, it can enable the user's touch gesture operations to obtain confirmatory feedback information, reducing the accidental operation rate. Thus, integrating touch gesture interaction into the common operations of the intelligent interaction tablet makes the user's operations more efficient; and adding the tactile feedback effect improves the user experience. Thereby, it can solve the problems that the mechanical physical buttons of the existing intelligent interaction tablet affect the overall appearance integrity of the intelligent interaction tablet, reduce the overall dustproof and waterproof performance of the intelligent interaction tablet, and the lack of tactile feedback in the virtual buttons on the touch screen leads to accidental triggering.

[0032] To facilitate the understanding of the above inventive concept of the present invention, the following will further elaborate on the above inventive concept of the present invention in conjunction with the accompanying drawings and specific embodiments.

[0033] In one embodiment, as Figure 1 shown, the present invention provides a virtual button interaction method for an intelligent interaction tablet, including:

[0034] S1. Obtain the pressing force applied to the virtual button area on the intelligent interactive tablet when the virtual button area is touched;

[0035] S2. Identify the touch gesture operation according to the pressing force and the preset touch gesture judgment rule;

[0036] S3. Generate vibration according to the touch gesture operation and provide haptic feedback matching the touch gesture operation.

[0037] In this embodiment, by providing a virtual button interaction method for an intelligent interactive tablet, it includes obtaining the pressing force applied to the virtual button area on the intelligent interactive tablet when the virtual button area is touched; identifying the touch gesture operation according to the pressing force and the preset touch gesture judgment rule; generating vibration according to the touch gesture operation and providing haptic feedback matching the touch gesture operation. Thus, by obtaining the pressing force applied to the virtual button area on the intelligent interactive tablet when the virtual button area is touched, the pressing force for pressing the virtual button area set in the intelligent interactive tablet can be obtained, and by setting the virtual button area in the intelligent interactive tablet, there are no mechanical physical buttons on the whole intelligent interactive tablet, optimizing the appearance of the intelligent interactive tablet, increasing the appearance integrity of the whole intelligent interactive tablet, and improving the overall dustproof and waterproof performance of the intelligent interactive tablet; by according to the pressing force and the preset touch gesture judgment rule, the touch gesture operation when the user touches the virtual button area can be accurately identified, which can make the adjustment of the parameters of the intelligent interactive tablet more convenient, intuitive and efficient; by generating vibration according to the touch gesture operation and providing haptic feedback matching the touch gesture operation, the user's touch gesture operation can obtain confirmatory feedback information, reducing the misoperation rate. Thus, integrating touch gesture interaction into the common operations of the intelligent interactive tablet makes the user's operation more efficient; and adding the haptic feedback effect improves the user experience. Thus, it can solve the problems that the mechanical physical buttons of the existing intelligent interactive tablet affect the appearance integrity of the intelligent interactive tablet, reduce the overall dustproof and waterproof performance of the intelligent interactive tablet, and the virtual buttons in the touch screen lack haptic feedback, resulting in mis-triggering.

[0038] In one embodiment, in step S1, obtain the pressing force applied to the virtual button area on the intelligent interactive tablet when the virtual button area is touched.

[0039] Specifically, the intelligent interactive flat panel as a whole does not have mechanical physical buttons. A virtual button area is set on the frame of the intelligent interactive flat panel. The virtual button area can be touched and can generate tactile feedback driven by vibration generated from a driver. Function identifiers of specific virtual buttons are screen-printed on the virtual button area, without opening slots on the outer shell structure of the intelligent interactive flat panel to set mechanical physical buttons. Therefore, compared with the hardware method of setting multiple mechanical physical buttons on the outer surface of the intelligent interactive flat panel, the intelligent interactive flat panel as a whole does not have mechanical physical buttons, optimizing the appearance of the intelligent interactive flat panel, increasing the appearance integrity of the intelligent interactive flat panel as a whole, and improving the overall dust and water resistance performance of the intelligent interactive flat panel.

[0040] When a user performs a touch gesture operation on the virtual button area of the intelligent interactive flat panel, a touch detection module set below the virtual button area can detect and obtain the pressing force applied to the touch screen. Specifically, one end of the touch detection module is coupled to the virtual button area, and the other end of the touch detection module is electrically connected to a processor. When the touch detection module works, it outputs the pressure value of the pressing force to the processor, and the processor processes the pressing force.

[0041] For example, the touch detection module can include a pressure sensor or a vibration sensor. The pressure sensor can include a resistive strain pressure sensor or a piezoelectric ceramic pressure sensor.

[0042] In one embodiment, in step S2, according to the pressing force and a preset touch gesture judgment rule, the touch gesture operation is identified.

[0043] When a user performs a touch gesture operation on the virtual button area of the intelligent interactive flat panel, a touch detection module coupled below the virtual button area can detect and obtain the pressing force applied to the touch screen. The touch detection module outputs the pressure value of the pressing force to a processor electrically connected to it, and the processor processes the pressing force.

[0044] The processor compares the pressure value of the pressing force with a preset pressure threshold and, in combination with a preset touch gesture judgment rule, identifies the touch gesture operation related to the pressing force. Among them, the preset pressure threshold includes a first pressure threshold and a second pressure threshold, and the first pressure threshold is lower than the second pressure threshold.

[0045] Specifically, if the pressure value of the pressing force exceeds the first pressure threshold and is lower than the second pressure threshold, and the change in finger position is lower than the first position threshold, then the touch gesture operation is identified as a light touch.

[0046] If two consecutive touches are both identified as light touches, and the time between the two light touches is less than the first time threshold, then the touch gesture operation is further identified as a double click.

[0047] If two consecutive touches are both recognized as tap gestures in the touch gesture operation, and the time between the two taps is greater than the first time threshold, then it is further recognized that the touch gesture operation is a single click.

[0048] If the pressure value of the pressing force exceeds the first pressure threshold and is lower than the second pressure threshold, and the change in finger position is higher than the first position threshold, then the touch gesture operation is recognized as a user swipe.

[0049] If the pressure value of the pressing force exceeds the second pressure threshold, then the touch gesture operation is recognized as a hard press.

[0050] In this embodiment, by combining the comparison result of the pressure value of the pressing force with the preset pressure thresholds (the first pressure threshold and the second pressure threshold), and then combining the comparison result of the change in finger position with the first position threshold, it is possible to accurately recognize various different touch gesture operations including double click, single click, swipe, or hard press, etc. performed by the user in the virtual button area of the intelligent interaction tablet. Compared with the software method, the multiple touch gesture operation interactions can make the frequently used function operations more intuitive and efficient, and make the adjustment of the parameters of the intelligent interaction tablet more convenient, intuitive, and efficient.

[0051] In one embodiment, in step S3, vibrations are generated according to the touch gesture operation to provide haptic feedback matching the touch gesture operation.

[0052] When the user performs a touch gesture operation in the virtual button area of the intelligent interaction tablet, the touch detection module coupled below the virtual button area can detect and obtain the pressing force applied to the virtual button area. The touch detection module outputs the pressure value of the pressing force to the processor electrically connected to it, and the processor processes the pressing force. The processor compares the pressure value of the pressing force with the preset pressure threshold, and combines the preset touch gesture judgment rule to recognize the touch gesture operation when the user performs a touch operation in the virtual button area of the intelligent interaction tablet, and sends a vibration control signal to the driver to generate vibrations according to the recognized touch gesture operation, providing haptic feedback matching the touch gesture operation.

[0053] Therefore, the vibration is generated by a driver which is used to generate vibration according to the vibration control signal of a processor and provide haptic feedback matching the touch gesture operation. Specifically, one end of the driver is coupled to the virtual key area, and the other end of the driver is electrically connected to a processor. The driver is used to generate vibration according to the vibration control signal of the processor, drive the virtual key area to generate vibration, so as to generate a haptic feedback effect and enhance the user experience. Since the touch gesture operations identified by the processor according to the pressing force and the preset touch gesture judgment rules include various different touch gesture operations such as double-click, single-click, slide, or heavy press, etc., the driver can also be correspondingly set with multiple vibration modes, and generate different vibration amplitudes and vibration frequencies according to the control instructions output by the processing module to respectively correspond to various different touch gesture operations, which can be specifically set according to actual needs.

[0054] For example, the driver may include a Linear Resonant Actuator (LRA), or may include a voice coil motor, or may include a piezoelectric ceramic actuator. Among them, the piezoelectric ceramic actuator may include a single-layer piezoelectric ceramic actuator to reduce the voltage of the drive electrical signal; or may include a multi-layer piezoelectric ceramic actuator to further reduce the voltage of the drive electrical signal.

[0055] In this embodiment, by generating vibration according to the vibration control signal of the processor through the driver and providing haptic feedback matching the touch gesture operation, compared with the software method, the user's touch gesture operation can obtain confirmatory feedback information, and the misoperation rate can be reduced.

[0056] In one embodiment, as Figure 2 shown, the virtual key interaction method of the intelligent interactive flat panel further includes: S4. According to the identified touch gesture operation, call out the preset function corresponding to the touch gesture operation to implement the interaction operation.

[0057] The intelligent interactive flat panel has preset various preset functions corresponding to touch gesture operations in the system. When the processor identifies the touch gesture operation when the user performs a touch operation in the virtual key area of the intelligent interactive flat panel, the processor will call out the preset function corresponding to the touch gesture operation from the touch screen system, so as to implement the interaction operation and make the adjustment of the parameters of the intelligent interactive flat panel more convenient, intuitive and efficient.

[0058] For example, taking the large-size intelligent interactive flat panel as an example, a virtual key area is set on the border of the large-size intelligent interactive flat panel, and the following preset functions can be realized in the virtual key area of the large-size intelligent interactive flat panel: power switch, eye protection mode, setting mode, volume down, volume up, screen recording mode.

[0059] Since the touch gesture operations recognized by the processor according to the pressing force and the preset touch gesture judgment rules include various different touch gesture operations such as double - click, single - click, swipe, or heavy press, correspondingly, the system of this large - size intelligent interactive tablet pre - sets the preset functions corresponding to the above various touch gesture operations. For example:

[0060] The touch gesture operations of single - click / heavy press can enable the eye - protection mode, the setting mode, and the screen recording mode.

[0061] The touch gesture operation of heavy press can enable the power switch, thus avoiding accidental touch.

[0062] The touch gesture operation of swiping can enable volume increase or volume decrease. Specifically, it can be adjusted by swiping the finger up and down in the virtual key area. When the finger swipes up in the virtual key area, volume increase is enabled; when the finger swipes down in the virtual key area, volume decrease is enabled.

[0063] The touch gesture operation of double - click can be used to define more interactive operations. For example: double - click can achieve screenshot taking, and double - click can return to the home page.

[0064] In this embodiment, according to the recognized touch gesture operation, the preset function corresponding to the touch gesture operation can be called up, the interactive operation can be realized, and the adjustment of the parameters of the intelligent interactive tablet can be made more convenient, intuitive, and efficient, thereby improving the interactive efficiency of the whole intelligent interactive tablet; and for the power - on / off function, only the touch gesture operation of heavy press can enable it, thus avoiding accidental touch. Compared with the hardware method, for the adjustment of continuous parameters, such as volume adjustment and brightness adjustment, the touch gesture operation of swiping is more convenient and efficient.

[0065] Based on the same concept, in one embodiment, as Figure 3 shown, the present invention also provides an intelligent interactive tablet 900, including: a touch detection module 904, a processor 901, and a driver 905. The processor 901 is electrically connected to the touch detection module 904 and the driver 905 respectively; wherein:

[0066] The touch detection module 904 is used to obtain the pressing force applied to the virtual key area on the intelligent interactive tablet when the virtual key area is touched, and transmit it to the processor 901;

[0067] The processor 901 is used to recognize the touch gesture operation according to the pressing force and the preset touch gesture judgment rules, and send a vibration control signal to the driver 905;

[0068] The driver 905 is used to generate vibration according to the vibration control signal of the processor 901 and provide a tactile feedback matching the touch gesture operation.

[0069] For example, the touch detection module 904 can be a pressure sensor or can include a vibration sensor. The pressure sensor can include a resistive strain pressure sensor or can include a piezoelectric ceramic pressure sensor.

[0070] The driver 905 can include a Linear Resonant Actuator (LRA), can also include a voice coil motor, or can include a piezoelectric ceramic actuator. Among them, the piezoelectric ceramic actuator can include a single-layer piezoelectric ceramic actuator to reduce the voltage of the driving electrical signal; or can include a multi-layer piezoelectric ceramic actuator to further reduce the voltage of the driving electrical signal.

[0071] In this embodiment, by providing an intelligent interactive tablet, including a touch detection module, a processor, and a driver, the processor is electrically connected to the touch detection module and the driver respectively; wherein: the touch detection module is used to obtain the pressing force applied to the virtual button area on the intelligent interactive tablet when the virtual button area is touched, and transmit it to the processor; the processor is used to identify the touch gesture operation according to the pressing force and the preset touch gesture judgment rule, and send a vibration control signal to the driver; the driver is used to generate vibration according to the vibration control signal of the processor to provide haptic feedback matching the touch gesture operation. Thus, by obtaining the pressing force applied to the virtual button area on the intelligent interactive tablet when the virtual button area is touched, the pressing force of pressing the virtual button area set in the intelligent interactive tablet can be obtained, and a virtual button area is set in the intelligent interactive tablet, so that the whole intelligent interactive tablet has no mechanical physical buttons, optimizing the appearance of the intelligent interactive tablet, increasing the overall appearance integrity of the intelligent interactive tablet, and improving the overall dust and waterproof performance of the intelligent interactive tablet; by according to the pressing force and the preset touch gesture judgment rule, the touch gesture operation when the user touches the virtual button area can be accurately identified, making the adjustment of the parameters of the intelligent interactive tablet more convenient, intuitive, and efficient; by generating vibration according to the touch gesture operation to provide haptic feedback matching the touch gesture operation, the user's touch gesture operation can obtain confirmatory feedback information, reducing the misoperation rate. Thus, the touch gesture interaction is integrated into the common operations of the intelligent interactive tablet, making the user's operation more efficient; and adding the haptic feedback effect to enhance the user experience. Thus, the problems that the mechanical physical buttons of the existing intelligent interactive tablet affect the overall appearance integrity of the intelligent interactive tablet, reduce the overall dust and waterproof performance of the intelligent interactive tablet, and the virtual buttons in the touch screen lack haptic feedback leading to mis-triggering can be solved.
