Referring to fig. 1, fig. 1 is a schematic structural diagram of a head-mounted device 10 according to an embodiment of the present disclosure.

As shown in fig. 1, a head-mounted device 10 provided in an embodiment of the present application may include: a host 100 and a handle 200. Where host 100 may be worn on the head of a user, it may be used to implement functions such as virtual reality or augmented reality. The handle 200 may establish a communication connection with the host 100 such that a user may interact with the host 100 through the handle 200. Meanwhile, the handle 200 can provide various tactile feedback effects for the user during the interaction process, so as to bring better tactile interaction experience for the user.

The host 100 may be worn on the head of a user and may implement virtual reality or augmented reality functionality in front of the user's eyes. As shown in fig. 1, host 100 may include a wearable cradle 110 and a display mechanism 120. The wearing support 110 may be worn on the head of the user, the display mechanism 120 may be disposed on the wearing support 110, and when the wearing support 110 is worn on the head of the user, the display mechanism 120 may be located in front of the eyes of the user, which may be used to implement a function of virtual reality or augmented reality. In this embodiment, the display mechanism 120 may be used to implement a virtual reality function, and a user may implement human-computer interaction by cooperating with a virtual picture displayed by the display mechanism 120 through the handle 200.

In the embodiment of the present application, all the directional indicators (such as upper, lower, left, right, front, and rear … …) are used only to explain the relative positional relationship between the components, the movement, and the like in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Referring to fig. 2 to 3, fig. 2 is a schematic structural view of the handle 200 in fig. 1, and fig. 3 is a schematic structural view of a partial cross section of the handle 200 in fig. 2 along v-v.

The handle 200 may establish a communication connection with the host 100 through a wired and/or wireless manner such that a user may interact with the host 100 through the handle 200. As shown in fig. 2 to 3, the handle 200 may include: a handle body 210 and a bladder 220. The handle body 210 can be held by a user, and functional components such as a battery, a sensor, and a main board can be mounted in the handle body 210. The bladder 220 may be disposed on an outer surface of the handle body 210, and the bladder 220 may be deformed multiple times under the control of the handle body 210 to generate an acting force to provide tactile feedback to the user. In this embodiment, after the airbag 220 is deformed for a plurality of times under the control of the handle body 210, the haptic feedback effects such as vibration, extrusion, friction, and the like can be generated, so as to improve the diversity of the haptic feedback effects provided when the handle 200 interacts with the user, thereby bringing better haptic interaction experience to the user.

Specifically, the handle body 210 may include: a grip 211 and a pressure portion 212. The grip 211 may be used to be held by a user, so that the user may use the handle 200 while gripping it in his hand. The pressing part 212 may be provided on the holding part 211, which may enable a user to interact with the handle body 210 by being touched or pressed. Meanwhile, since the grip portion 211 and the pressing portion 212 are both in contact with the palm of the user, in order to provide the user with corresponding tactile feedback, the airbag 220 may be disposed on at least one of the grip portion 211 and the pressing portion 212, so that the user can feel a tactile feedback effect caused by deformation of the airbag 220 when contacting the grip portion 211 or the pressing portion 212.

Further, the grip 211 may be mounted with various kinds of functional components required for the handle body 210. As shown in fig. 2 to 3, the grip portion 211 may have a contact surface 2111 and a mounting surface 2112. Among other things, the contact surface 2111 may contact the palm of the user's hand when the user grips the grip portion 211, which may be used to mount the airbag 220 so that the airbag 220 brings tactile feedback to the user. The mounting surface 2112 may be connected to the contact surface 2111, and the contact surface 2111 may be provided around an edge of the mounting surface 2112, which may be used for mounting the hold-down portion 212. Preferably, the shape of the holding portion 211 may also be designed according to human engineering, so that the user can grip the holding portion 211 conveniently, and comfort of the user gripping the holding portion 211 is improved.

The pressing part 212 may be disposed on the contact surface 2111, and the pressing part 212 may realize the interaction of the user with the handle body 210 by being pressed or touched. As shown in fig. 2 to 3, the pressing portion 212 may include: at least one of a key 2121 and a touch pad 2122. The keys 2121 may be disposed on the mounting surface 2112, and the keys 2121 may have a certain moving stroke in a direction perpendicular to the mounting surface 2112, so that the keys 2121 may be pressed to enable a user to interact with the handle body 210. The touch pad 2122 can be disposed in the holding portion 211, and the touch pad 2122 can further form a corresponding touch area 2001 on the mounting surface 2112, so that the touch pad 2122 can enable a user to interact with the handle body 210 by being touched. Alternatively, the pressing part 212 may include other parts capable of contacting with the user, such as a trigger, a rocker, and the like, in addition to the key 2121 and the touch pad 2122.

The air bag 220 may be disposed on at least one of the holding portion 211 and the pressing portion 212, and may be controlled by the handle body 210 to perform multiple cycles of expansion and contraction, so that multiple deformations occur to generate an acting force to provide a tactile feedback to the user. As shown in fig. 2 to 3, the airbag 220 may be provided on a contact surface 2111 of the grip portion 211 so that a user can contact with the airbag 220 when gripping the grip portion 211. At the same time, the bladder 220 preferably covers a substantial area of the contact surface 2111 to increase the area of the bladder 220 that can contact the user, thereby providing a better tactile feedback experience for the user. The air bag 220 may be provided on the button 2121 and the touch pad 2122. For example, the air cell 220 may be provided on a surface of the key 2121 that is pressed by the user, such that the user can contact the air cell 220 when pressing the key 2121, thereby obtaining a corresponding tactile feedback. Similarly, the air bag 220 may also be disposed on the touch area 2001 formed on the mounting surface 2112 by the touchpad 2122, so that the user can contact with the air bag 220 when touching the touch area 2001, thereby obtaining the corresponding tactile feedback.

Specifically, when the airbag 220 is provided on the grip portion 211, the number of airbags 220 may be two, and the two airbags 220 may be a first airbag 221 and a second airbag 222, respectively. As shown in fig. 3, the first airbag 221 and the second airbag 222 may be respectively located at opposite sides of the grip portion 211, and inflation and deflation of the first airbag 221 and the second airbag 222 may be independent. The handle body 210 can respectively and cyclically inflate and deflate the first air bag 221 and the second air bag 222, so that the first air bag 221 and the second air bag 222 cyclically expand and contract to realize multiple deformation of the first air bag 221 and the second air bag 222, and thus, acting force is generated to bring tactile feedback effects such as vibration, extrusion, friction and the like to a user. The terms "first", "second" and "third" in this application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or as implying a number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature.

For example, the handle body 210 may inflate and deflate the first balloon 221 and the second balloon 222 for a plurality of cycles at the same time, so that the first balloon 221 and the second balloon 222 may be inflated and deflated at the same time. When the user grips the grip portion 211, the user can feel a pressing feeling caused by repeated inflation of the first airbag 221 and the second airbag 222. For another example, the handle body 210 inflates the first balloon 221, then inflates the second balloon 222, and when inflating the second balloon 222, the first balloon 221 may be in a deflated and deflated state, so that one of the first balloon 221 and the second balloon 222 may be inflated and the other may be deflated at the same time, thereby biasing the handle body 210. When the user grips the grip 211, the user feels a vibration caused by the first air bag 221 and the second air bag 222 expanding successively.

Alternatively, the first airbag 221 and the second airbag 222 may be divided by a whole airbag 220, and only the first airbag 221 and the second airbag 222 need to maintain the independence of inflation and deflation. Alternatively, only one airbag 220 may be provided, and it may be provided on one side of the grip portion 211. The handle body 210 may also be biased to provide a vibratory tactile feedback effect when the handle body 210 cyclically inflates and deflates the balloon 220. It is understood that besides the aforementioned vibration and squeezing haptic feedback effects, a plurality of different haptic feedback effects can be modulated by adjusting the inflation and deflation time, frequency and amount of inflation and deflation of the air bag 220, which is not illustrated here. It should be noted that the expressions described above with respect to the "airbag", "first airbag", and "second airbag" are merely intended to show a difference in number. In some embodiments, the "balloon" may also be referred to as the "first balloon" or the "second balloon". Similarly, the "first balloon" may also be referred to as the "balloon" or "second balloon", and the "second balloon" may also be referred to as the "balloon" or "first balloon".

Further, the handle 200 may be provided with an air pump 230 for inflating and deflating the air bag 220. As shown in fig. 3, the air pump 230 may be disposed in the holding portion 211, and the air pump 230 may be in communication with the air bag 220 through an air path, and may perform cyclic inflation and deflation on the air bag 220, so that the air bag 220 performs a cycle of multiple inflation and deflation, thereby realizing multiple deformation of the air bag 220. Among them, the air pump 230 may preferably be a piezoceramic air pump to reduce the volume and weight of the air pump 230, thereby facilitating the design of miniaturization and lightweight of the handpiece 200. Of course, the air pump 230 may also be an air pump such as an electric motor, and only the air pump 230 is required to inflate and deflate the airbag 220.

Referring to fig. 4 to 5, fig. 4 is a partial structural view of the airbag 220 in fig. 2, and fig. 5 is another partial structural view of the airbag 220 in fig. 2.

The air bag 220 can be provided with a plurality of sub air bags 223, and the handle body 210 can control the expansion and contraction of the sub air bags 223 through circularly inflating and deflating the sub air bags 223, so that the integral multi-deformation of the air bag 220 is realized. As shown in fig. 4, the sub-air bags 223 can be communicated with each other, so that the handle body 210 can inflate and deflate the sub-air bags 223 at the same time, so as to inflate and deflate the whole air bag 220, and simplify the control process. As shown in fig. 5, the sub-airbags 223 may be independent, and the sub-airbags 223 may be connected to the handle body 210 through independent air paths, so that the handle body 210 may independently control the inflation and deflation of a certain sub-airbag 223, so as to improve the response speed (inflation and deflation speed) of the single sub-airbag 220 as a whole, and realize the local inflation and deflation control of the airbag 220. Optionally, the sub-airbags 223 may also be partially communicated and partially independent, and not limited to being completely communicated or completely independent, and whether the sub-airbags 223 are independent or communicated may be adjusted according to the design requirement of the whole airbag 220, which is not limited in this embodiment. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless explicitly specifically limited otherwise.

Referring to fig. 6 to 8, fig. 6 is a flowchart illustrating a control method according to an embodiment of the present disclosure, fig. 7 is a waveform illustrating a preset driving signal according to an embodiment of the present disclosure, and fig. 8 is another waveform illustrating the preset driving signal according to an embodiment of the present disclosure.

The control method provided by the embodiment of the present application may be used for controlling the handle 200 in the foregoing embodiment, as shown in fig. 6, the control method may specifically include the following steps:

and S10, acquiring a trigger signal.

And S30, determining a preset driving signal according to the trigger signal.

And S50, controlling the air bag to deform for multiple times in response to a preset driving signal.

Specifically, the trigger signal may be obtained by the interaction between the user and the handle 200, or may be obtained by a signal transmitted from the host 100 or an external device to the handle 200. For example, when the user grips the grip portion 211, a detection component (such as a capacitive touch pad or various sensors) disposed in the grip portion 211 can detect the gripping behavior of the user, so that the handle 200 can acquire the corresponding trigger signal. Alternatively, when the user presses the key 2121 or touches the touch area 2001 formed by the touch pad 2122, the handle 200 may obtain the corresponding trigger signal through the pressing or touching action of the user. Alternatively, when the user plays a game through the virtual screen displayed by the host 100 and enters a specific game scene, the host 100 may transmit a signal to the handle 200, so that the handle 200 acquires a corresponding trigger signal according to the signal.

Alternatively, the trigger signal may be generated by the handle 200 itself without interaction with the user, the host 100 or an external device, in addition to the manner of acquiring the trigger signal described above. For example, when the time for a user to use the handle 200 once reaches a preset time, the handle 200 itself may generate a corresponding trigger signal, so that the handle 200 provides tactile feedback to the user to remind the user. Of course, the trigger signal may also be obtained from more usage scenarios, and this embodiment is not listed here.

Further, after the handle 200 acquires the trigger signal, it may determine a preset driving signal corresponding to the trigger signal according to a pre-stored relationship comparison table, and then control inflation and deflation of the airbag 220 in response to the preset driving signal, so that the airbag 220 may expand or contract according to the preset driving signal, and further achieve the purpose that the airbag 220 deforms for many times to generate an acting force to provide tactile feedback for the user. For example, the trigger signal may be classified into the aforementioned first category acquired by the interaction of the user and the handle 200, and the second category acquired by the host 100 or the external device transmitting the signal of the handle 200. The preset driving signal corresponding to the first type of trigger signal may enable the air bag 220 to have a vibratory haptic feedback effect, and the preset driving signal corresponding to the second type of trigger signal may enable the air bag 220 to have a squeezing haptic feedback effect. As such, the handle 200 may have two different haptic feedback effects, thereby giving the user a different haptic feedback experience. It is understood that the foregoing two types of trigger signals are only for illustration, and the trigger signals may be actually not limited to the foregoing two types, and may be divided into more types according to the requirement, so that the handle 200 can provide more tactile feedback effects for the user, which is not listed here.

Further, the preset driving signal may be a PWM (Pulse Width Modulation) signal, and the handle 200 may drive the air pump 230 to operate in response to the waveform of the preset driving signal to control the selection of the inflation and deflation of the air bag 220 and the duration and period of the inflation and deflation, so that the air bag 220 may be deformed (expanded or contracted) multiple times to provide the acting force to provide the tactile feedback to the user. As shown in fig. 7, the waveform of the preset driving signal provided by the embodiment of the present application may be a square wave, and the voltage range may be-15V to 15V. When the voltage of the preset driving signal is in the switching state a, the air pump 230 may be in a working state of inflating the air bag 220. When the voltage of the preset driving signal is in the holding state B of being normally high or low, the air pump 230 may be in a non-operating state where the air bag 220 is not inflated, and at this time, the air bag 220 may be deflated. In the present embodiment, the switching state a may be a state in which the voltage value of the preset driving signal is switched from 15V to-15V or from-15V to 15V in a continuous time. The holding state B may be a state in which the voltage value of the preset drive signal is held at 15V constant high or held at-15V constant low for a continuous time.

With the above arrangement, the handle 200 can control not only inflation and deflation of the air bag 220 in response to the switching state a and the holding state B in the preset drive signal, but also control the inflation and deflation time of the air bag 220 in response to the duration of the switching state a and the holding state B. Meanwhile, one continuous switching state a and holding state B may be a period of the preset driving signal, and the inflation and deflation cycle of the airbag 220 may be implemented by increasing the period number of the preset driving signal in a unit time (e.g., half second, 1 second, or two seconds), so that the airbag 220 performs cyclic inflation and deflation, and then generates vibration of several tens or hundreds of hertz, so as to bring different haptic feedback effects such as vibration, extrusion, friction, and the like to the user.

Alternatively, the driving manner of the air pump 230 may not be limited to the above embodiment. For example, when the preset driving signal is in the switching state a, the air pump 230 may be in a non-operating state. When the preset driving signal is in the hold state B, the air pump 230 may be in an operating state. Alternatively, when the voltage value of the preset driving signal is maintained at 15V for a continuous time, the air pump 230 may be in an operating state. When the voltage value of the preset driving signal is kept at-15V and low for a continuous time, the air pump 230 may be in a non-operating state. That is, the driving of the air pump 230 may be adaptively adjusted according to the variation of the waveform of the preset driving signal. In addition, the voltage range of the preset driving signal may not be limited to-15V to 15V, and the specific voltage range may also be adjusted according to design requirements, which is not limited in this embodiment.

Further, in addition to the above manner, the inflation amount of the air pump 230 to the air bag 220 can be adjusted by adjusting the voltage of the preset driving signal, so as to achieve the purpose of controlling the deformation amount of the air bag 220. As shown in fig. 8, the handle 200 may adjust the voltage range of the preset driving signal according to the preset output voltage, so that the voltage range of the preset driving signal is changed from-15V or 15V, which is constant, to-8V to 8V within a certain time period, so as to reduce the current input to the air pump 230 within the time period, and further reduce the power of the air pump 230, so that the inflation amount of the air bag 220 by the air pump 230 is reduced. Similarly, when the next time period is started, the preset driving voltage range can be changed from-8V to-15V or 15V to increase the current input to the air pump 230, so that the inflation amount of the air pump 230 to the airbag 220 is increased. In this embodiment, the preset output voltage may be bound to the trigger signal in advance through a relation table, so that when the handle 200 determines the preset driving signal through the trigger signal, the preset output voltage is also determined, and the air pump 230 is driven by combining the preset driving signal and the preset output voltage. It is to be understood that the foregoing voltage range of the preset driving signal adjusted according to the preset output voltage is merely an exemplary illustration, and the change of the preset output voltage may not be limited to the foregoing embodiment, which may be adaptively adjusted according to design requirements (as shown in fig. 8), and the embodiment is not listed here.

Through the control method, the handle 200 can determine the preset driving signal and the preset output voltage through the trigger signal, and drive the air pump 230 by combining the waveform of the preset driving signal and the preset output voltage, so that the air bag 220 can be modulated with various different haptic feedback effects, such as vibration, extrusion, friction or various combined touch senses, thereby increasing the diversity of the haptic feedback effects which can be provided by the handle 200 and improving the haptic feedback experience of a user.

Referring to fig. 9 to 10, fig. 9 is a schematic diagram illustrating a structure of a handle 200 according to an embodiment of the present disclosure, and fig. 10 is a circuit diagram illustrating the air pump driver 203 in fig. 9.

As shown in fig. 9, the structure of the handle 200 may include: a processor 201, a power manager 202, an air pump driver 203, an air pump 204 (equivalent to the air pump 230 of the foregoing embodiment), an air bag 205 (equivalent to the air bag 220 of the foregoing embodiment), a wireless communication unit 206, a sensor 207, an input unit 208, and a memory 209. The power manager 202, the air pump driver 203, the wireless communication unit 206, the sensor 207, the input unit 208, and the memory 209 are respectively connected to the processor 201, and the air pump driver 203 is further connected to the power manager 202. The air pump 204 is connected to the air pump driver 203, and the air bag 205 is connected to the air pump 204.

Specifically, the processor 201 may be used to process data information of the handpiece 200. The power manager 202 may have a power source that may be used to provide power to the entire handpiece 200. The air pump driver 203 may be configured to drive the air pump 204 in response to the aforementioned preset drive signal. The air pump 204 can inflate the air bag 205 under the driving of the air pump driver 203, so that the air bag 205 is deformed to generate acting force to provide tactile feedback for the user. Meanwhile, fig. 10 shows an alternative circuit diagram of the air pump driver 203 in the present embodiment. Of course, the circuit design of the air pump driver 203 may also be not limited to that shown in fig. 10. The wireless communication unit 206 may be used to receive and transmit electromagnetic wave signals to implement the wireless communication function of the handpiece 200.
