[0018] The present application is further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0019] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The present application describes a head-mounted device. The head-mounted device may be an augmented reality or virtual reality device, such as augmented reality or virtual reality glasses. Of course, the head-mounted device may also be other devices that need to be worn on the head, such as devices that have other functions such as lighting or video recording and can be worn on the head, which will not be described in detail here. The following is a detailed description of the head-mounted device being augmented reality or virtual reality glasses as an example.

[0021] In the example of augmented reality or virtual reality glasses, the head-mounted device can be configured to pass data to and receive data from an external processing device via a signal connection, and the signal connection can be a wired connection, a wireless connection, or a combination thereof. However, in other cases, the head-mounted device can be used as a standalone device, that is, data processing is performed on the head-mounted device itself. The signal connection can be configured to carry any kind of data, such as image data (e.g., still images and / or full motion video, including 2D and 3D images), audio, multimedia, voice, and / or any other type of data. The external processing device can be, for example, a game console, a personal computer, a tablet computer, a smart phone, or other type of processing device. The signal connection can be, for example, a universal serial bus (USB) connection, a Wi-Fi connection, a Bluetooth or Bluetooth low energy (BLE) connection, an Ethernet connection, a cable connection, a DSL connection, a cellular connection (e.g., 3G, LTE / 4G or 5G), etc., or a combination thereof. Additionally, the external processing device may communicate with one or more other external processing devices via a network, which may be or include, for example, a local area network (LAN), a wide area network (WAN), an intranet, a metropolitan area network (MAN), the global Internet, or a combination thereof.

[0022] The head mounted device may include a display assembly, optical devices, sensors, and processors. In the example of augmented reality or virtual reality glasses, the display assembly is designed to, for example, implement the functions of virtual reality glasses by projecting light into the user's eyes, for example, by projecting light into the user's eyes and overlaying images on the user's view of their real world environment to implement the functions of augmented reality glasses. The head mounted device may also include an ambient light sensor, and may also include an electronic circuit system to control at least some of the above components and perform associated data processing functions. The electronic circuit system may include, for example, one or more processors and one or more memories.

[0023] See also Figure 1 , Figure 1 It is a schematic diagram of the structure of the head mounted device 10 provided in an embodiment of the present application.

[0024] like Figure 1 As shown, the head mounted device 10 provided in the embodiment of the present application may include: a host 100 and a handle 200. Among them, the host 100 can be worn on the user's head, and it can be used to realize functions such as virtual reality or augmented reality. The handle 200 can establish a communication connection with the host 100, so that the user can interact with the host 100 through the handle 200. At the same time, the handle 200 can also provide the user with a variety of tactile feedback effects during the interaction process, so as to bring the user a better tactile interaction experience.

[0025] The host 100 can be worn on the user's head and can realize the functions of virtual reality or augmented reality in front of the user's eyes. Figure 1 As shown, the host 100 may include a wearing bracket 110 and a display mechanism 120. The wearing bracket 110 may be worn on the user's head, and the display mechanism 120 may be arranged on the wearing bracket 110, and when the wearing bracket 110 is worn on the user's head, the display mechanism 120 may be located in front of the user's eyes, which may be used to realize the function of virtual reality or augmented reality. In this embodiment, the display mechanism 120 may be used to realize the function of virtual reality, and the user may realize human-computer interaction by cooperating with the virtual screen displayed by the handle 200 and the display mechanism 120.

[0026] All directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0027] See also Figures 2 to 3 , Figure 2 yes Figure 1 A schematic structural diagram of the middle handle 200, Figure 3 yes Figure 2 Schematic diagram of the partial cross-sectional structure of the middle handle 200 along V-V.

[0028] The handle 200 can establish a communication connection with the host 100 in a wired and / or wireless manner, so that the user can interact with the host 100 through the handle 200. Figures 2 to 3 As shown, the handle 200 may include: a handle body 210 and an airbag 220. The handle body 210 may be held by a user, and functional components such as a battery, a sensor, and a mainboard may be mounted in the handle body 210. The airbag 220 may be disposed on the outer surface of the handle body 210, and the airbag 220 may be deformed multiple times under the control of the handle body 210 to generate a force to provide tactile feedback to the user. In this embodiment, the airbag 220 may generate tactile feedback effects such as vibration, extrusion, and friction after multiple deformations under the control of the handle body 210, so as to increase the diversity of tactile feedback effects that can be provided when the handle 200 interacts with the user, thereby providing the user with a better tactile interaction experience.

[0029] Specifically, the handle body 210 may include: a gripping portion 211 and a touch-and-press portion 212. The gripping portion 211 may be used to be held by the user, so that the user can hold the handle 200 in his hand for use. The touch-and-press portion 212 may be provided on the gripping portion 211, and the touch-and-press portion 212 may be touched or pressed to enable the user to interact with the handle body 210. At the same time, since both the gripping portion 211 and the touch-and-press portion 212 may contact the palm of the user, in order to provide the user with corresponding tactile feedback, the airbag 220 may be provided on at least one of the gripping portion 211 and the touch-and-press portion 212, so that the user can feel the tactile feedback effect brought about by the deformation of the airbag 220 when in contact with the gripping portion 211 or the touch-and-press portion 212.

[0030] Furthermore, the grip portion 211 may be equipped with various functional components required by the handle body 210. Figures 2 to 3 As shown, the grip portion 211 may have a contact surface 2111 and a mounting surface 2112. The contact surface 2111 may contact the palm of the user when the user grasps the grip portion 211, and may be used to install the airbag 220 so that the airbag 220 provides tactile feedback to the user. The mounting surface 2112 may be connected to the contact surface 2111, and the contact surface 2111 may be arranged around the edge of the mounting surface 2112, and may be used to install the touch-pressing portion 212. Preferably, the shape of the grip portion 211 may also conform to ergonomic design, so that the user can grasp the grip portion 211 and improve the comfort of the user grasping the grip portion 211.

[0031] The touch-pressing portion 212 may be disposed on the contact surface 2111, and the touch-pressing portion 212 may be pressed or touched to enable the user to interact with the handle body 210. Figures 2 to 3As shown, the touch-pressing portion 212 may include at least one of a button 2121 and a touch pad 2122. The button 2121 may be disposed on the mounting surface 2112, and the button 2121 may have a certain movable stroke in a direction perpendicular to the mounting surface 2112, so that the button 2121 can realize the interaction between the user and the handle body 210 by being pressed. The touch pad 2122 may be disposed in the grip portion 211, and the touch pad 2122 may also form a corresponding touch area 2001 on the mounting surface 2112, so that the touch pad 2122 can realize the interaction between the user and the handle body 210 by being touched. Optionally, in addition to the button 2121 and the touch pad 2122, the touch-pressing portion 212 may also include other components that can contact with the user, such as a trigger and a rocker.

[0032] The airbag 220 may be disposed on at least one of the grip portion 211 and the contact and pressure portion 212, and may undergo multiple cycles of expansion and contraction under the control of the handle body 210, thereby causing multiple deformations to generate forces to provide tactile feedback to the user. Figures 2 to 3 As shown, the airbag 220 can be arranged on the contact surface 2111 of the grip 211, so that the user can contact the airbag 220 when grasping the grip 211. At the same time, the airbag 220 preferably covers most of the contact surface 2111 to increase the area where the airbag 220 can contact the user, thereby providing the user with a better tactile feedback experience. The airbag 220 can also be arranged on the button 2121 and the touch pad 2122. For example, the airbag 220 can be arranged on the surface of the button 2121 pressed by the user, so that the user can contact the airbag 220 when pressing the button 2121, thereby obtaining corresponding tactile feedback. Similarly, the airbag 220 can also be arranged on the touch area 2001 formed by the touch pad 2122 on the mounting surface 2112, so that the user can also contact the airbag 220 when touching the touch area 2001, thereby obtaining corresponding tactile feedback.

[0033] Specifically, when the airbag 220 is disposed on the grip portion 211, the number of the airbags 220 may be two, and the two airbags 220 may be a first airbag 221 and a second airbag 222. Figure 3As shown, the first airbag 221 and the second airbag 222 can be located on opposite sides of the grip portion 211, and the first airbag 221 and the second airbag 222 can be charged and discharged independently. The handle body 210 can charge and discharge the first airbag 221 and the second airbag 222 cyclically, so that the first airbag 221 and the second airbag 222 are expanded and contracted in a cycle, so as to achieve multiple deformations of the first airbag 221 and the second airbag 222, thereby generating a force to bring tactile feedback effects such as vibration, squeezing and friction to the user. The terms "first", "second" and "third" in this application are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined as "first", "second" and "third" can explicitly or implicitly include at least one of the features.

[0034] For example, the handle body 210 can simultaneously inflate and deflate the first airbag 221 and the second airbag 222 for multiple cycles, so that the first airbag 221 and the second airbag 222 can expand and contract at the same time. When the user grasps the grip portion 211, the user can feel the squeezing feeling caused by the repeated expansion of the first airbag 221 and the second airbag 222. For another example, the handle body 210 first inflates the first airbag 221, and then inflates the second airbag 222, and when the second airbag 222 is inflated, the first airbag 221 can be in a state of deflation and contraction, so that the first airbag 221 and the second airbag 222 can expand and contract at the same time, thereby causing the handle body 210 to be offset. When the user grasps the grip portion 211, the user can feel the vibration feeling caused by the offset of the handle body 210 caused by the expansion of the first airbag 221 and the second airbag 222 one after another.

[0035] Optionally, the first airbag 221 and the second airbag 222 may also be formed by dividing a whole airbag 220, and it is only necessary that the first airbag 221 and the second airbag 222 can maintain the independence of inflation and deflation. Optionally, there may be only one airbag 220, which may be arranged on one side of the grip 211. When the handle body 210 cyclically inflates and deflates the airbag 220, the handle body 210 may also be biased to achieve a tactile feedback effect of vibration. It is understood that in addition to the aforementioned tactile feedback effects of vibration and compression, a variety of different tactile feedback effects may be modulated by adjusting the time, frequency and amount of inflation and deflation of the airbag 220, and this embodiment will not be illustrated one by one here. In addition, it should be noted that the aforementioned expressions of "airbag", "first airbag" and "second airbag" are only to reflect the difference in quantity. In some embodiments, "airbag" may also be referred to as "first airbag" or "second airbag". Similarly, the "first airbag" may also be referred to as the "airbag" or the "second airbag", and the "second airbag" may also be referred to as the "airbag" or the "first airbag".

[0036] Furthermore, in order to inflate and deflate the airbag 220, the handle 200 may also be provided with an air pump 230. Figure 3 As shown, the air pump 230 can be arranged in the grip portion 211, and the air pump 230 can be connected to the airbag 220 through an air path, and can cyclically inflate and deflate the airbag 220, so that the airbag 220 undergoes multiple cycles of expansion and contraction, thereby achieving multiple deformations of the airbag 220. Among them, the air pump 230 can preferably be a piezoelectric ceramic air pump to reduce the volume and weight of the air pump 230, thereby facilitating the miniaturization and lightweight design of the handle 200. Of course, the air pump 230 can also adopt other air pumps such as motor-type air pumps, as long as the air pump 230 can inflate and deflate the airbag 220.

[0037] See also Figures 4 to 5 , Figure 4 yes Figure 2 A partial structural diagram of the middle airbag 220, Figure 5 yes Figure 2 Another partial structural diagram of the middle airbag 220.

[0038] The airbag 220 may have a plurality of sub-airbags 223, and the handle body 210 may control the expansion and contraction of the sub-airbags 223 by cyclically inflating and deflating the sub-airbags 223, thereby achieving multiple deformations of the entire airbag 220. Figure 4 As shown, the multiple sub-airbags 223 can be connected, so that the handle body 210 can inflate and deflate the multiple sub-airbags 223 at the same time, so as to inflate and deflate the airbag 220 as a whole, simplifying the control process. Figure 5As shown, the multiple sub-airbags 223 can also be independent, and the multiple sub-airbags 223 can be connected to the handle body 210 through independent air paths, so that the handle body 210 can independently control the inflation and deflation of a certain sub-airbag 223, so as to improve the overall response speed (inflation and deflation speed) of a single sub-airbag 220, and can realize the local inflation and deflation control of the airbag 220. Optionally, the multiple sub-airbags 223 can also be partially connected and partially independent, but not limited to being fully connected or fully independent, and whether the multiple sub-airbags 223 are independent or connected can be adjusted according to the overall design requirements of the airbag 220, which is not limited in this embodiment. In the description of this application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0039] See also Figures 6 to 8 , Figure 6 is a flow chart of a control method provided in an embodiment of the present application, Figure 7 is a waveform diagram of a preset driving signal provided in an embodiment of the present application, Figure 8 is another waveform diagram of the preset driving signal provided in an embodiment of the present application.

[0040] The control method provided in the embodiment of the present application can be used to control the handle 200 in the aforementioned embodiment, such as Figure 6 As shown, the control method may specifically include the following steps:

[0041] S10, obtaining a trigger signal.

[0042] S30, determining a preset driving signal according to the trigger signal.

[0043] S50, controlling the airbag to deform multiple times in response to a preset driving signal.

[0044] Specifically, the trigger signal can be obtained by the interaction between the user and the handle 200, or by the signal transmitted to the handle 200 by the host 100 or an external device. For example, when the user grasps the grip 211, the detection component (such as a capacitive touch panel or various sensors, etc.) provided in the grip 211 can detect the user's grasping behavior, so that the handle 200 can obtain the corresponding trigger signal. Alternatively, when the user presses the button 2121 or touches the touch area 2001 formed by the touch panel 2122, the handle 200 can obtain the corresponding trigger signal through the user's pressing or touching behavior. 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 can transmit a signal to the handle 200 so that the handle 200 obtains the corresponding trigger signal according to the signal.

[0045] Optionally, in addition to the above-mentioned method of obtaining the trigger signal, the trigger signal can also be generated by the handle 200 itself, without the need for interaction with the user, the host 100 or an external device. For example, when the user uses the handle 200 for a preset time, the handle 200 itself can generate a corresponding trigger signal, so that the handle 200 provides tactile feedback to the user to achieve the purpose of reminding the user. Of course, the trigger signal can also be obtained from more usage scenarios, which are not listed one by one in this embodiment.

[0046] Further, when the handle 200 obtains the trigger signal, it can determine the preset drive signal corresponding to the trigger signal according to the pre-stored relationship comparison table, and then control the inflation and deflation of the airbag 220 in response to the preset drive signal, so that the airbag 220 can expand or contract according to the preset drive signal, thereby achieving the purpose of multiple deformations of the airbag 220 to generate force to provide tactile feedback to the user. For example, the trigger signal can be divided into the first category obtained by the interaction between the user and the handle 200, and the second category obtained by the host 100 or an external device transmitting the signal of the handle 200. Among them, the preset drive signal corresponding to the first type of trigger signal can make the airbag 220 have a vibration tactile feedback effect, and the preset drive signal corresponding to the second type of trigger signal can make the airbag 220 have a squeezing tactile feedback effect. In this way, the handle 200 can have two different tactile feedback effects, thereby bringing different tactile feedback experiences to the user. It is understandable that the above two types of trigger signals are only for illustration purposes, and the trigger signals are actually not limited to the above two types. They can be divided into more categories according to needs, so that the handle 200 can provide more tactile feedback effects for the user, which are not listed one by one in this embodiment.

[0047] Furthermore, the preset driving signal may be a PWM (Pulse Width Modulation) signal, and the handle 200 may drive the air pump 230 to work in response to the waveform of the preset driving signal to control the selection of inflation and deflation of the airbag 220 and the duration and cycle of inflation and deflation, so that the airbag 220 may be deformed (expanded or contracted) multiple times to provide a force to provide tactile feedback to the user. Figure 7As shown, the waveform of the preset drive signal provided in the embodiment of the present application can be a square wave, and the voltage range can be -15V to 15V. Wherein, when the voltage of the preset drive signal is in the switching state A, the air pump 230 can be in a working state of inflating the airbag 220. When the voltage of the preset drive signal is in the normally high or normally low holding state B, the air pump 230 can be in a non-working state of not inflating the airbag 220, and the airbag 220 can be deflated at this time. In the present embodiment, the switching state A refers to the state in which the voltage value of the preset drive signal is switched from 15V to -15V or from -15V to 15V in a continuous time. The holding state B refers to the state in which the voltage value of the preset drive signal is kept at 15V normally high or kept at -15V normally low in a continuous time.

[0048] Through the above settings, the handle 200 can not only control the inflation and deflation of the airbag 220 in response to the switching state A and the holding state B in the preset driving signal, but also control the inflation and deflation time of the airbag 220 in response to the duration of the switching state A and the holding state B. At the same time, a continuous switching state A and holding state B can be a cycle of the preset driving signal. By increasing the number of cycles of the preset driving signal within a unit time (such as half a second, 1 second or two seconds), the inflation and deflation cycle of the airbag 220 can be realized, so that the airbag 220 is cyclically expanded and contracted, and then tens or hundreds of hertz of vibration are generated, so as to bring different tactile feedback effects such as vibration, squeezing and friction to the user.

[0049] Optionally, the driving mode of the air pump 230 may also not be limited to the above-mentioned embodiments. For example, when the preset drive signal is in the switching state A, the air pump 230 may be in a non-operating state. When the preset drive signal is in the holding state B, the air pump 230 may be in a working state. Alternatively, when the voltage value of the preset drive signal remains 15V normally high for a continuous time, the air pump 230 may be in a working state. When the voltage value of the preset drive signal remains -15V normally low for a continuous time, the air pump 230 may be in a non-operating state. That is, the drive of the air pump 230 may be adaptively adjusted according to the change of the waveform of the preset drive signal. In addition, the voltage range of the preset drive signal may also be not limited to -15V to 15V, and its specific voltage range may also be adjusted according to design requirements, which is not limited in the present embodiment.

[0050] Furthermore, in addition to the above-mentioned method, the inflation amount of the airbag 220 by the air pump 230 can be adjusted by adjusting the voltage of the preset driving signal, thereby achieving the purpose of controlling the deformation amount of the airbag 220. Figure 8As shown, the handle 200 can 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 changes from a constant -15V or 15V to -8V to 8V in a certain time period, so as to reduce the current input to the air pump 230 in the time period, thereby reducing the power of the air pump 230, so that the air pump 230 reduces the amount of air inflated to the airbag 220. Similarly, when entering the next time period, the range of the preset driving voltage can be changed from -8V to 8V to -15V or 15V to increase the current input to the air pump 230, so that the air pump 230 increases the amount of air inflated to the airbag 220. In this embodiment, the preset output voltage can be pre-bound with the trigger signal through a relationship comparison table, so that when the handle 200 determines the preset driving signal through the trigger signal, it also determines the preset output voltage, and then drives the air pump 230 in combination with the preset driving signal and the preset output voltage. It is understandable that the aforementioned adjustment of the voltage range of the preset driving signal according to the preset output voltage is only an exemplary description, and the change of the preset output voltage is not limited to the aforementioned embodiment, and it can be adaptively adjusted according to design requirements (such as Figure 8 ), and this embodiment is not listed here one by one.

[0051] Through the above-mentioned 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 in combination with the waveform of the preset driving signal and the preset output voltage, so that the airbag 220 can be modulated to produce a variety of different tactile feedback effects, such as vibration, squeezing, friction or a combination of multiple tactile effects, thereby increasing the diversity of tactile feedback effects that the handle 200 can provide and enhancing the user's tactile feedback experience.

The air pump 204 is connected to the air pump driver 203, and the air bag 205 is connected to the air pump 204.

[0054] Specifically, the processor 201 can be used to process data information of the handle 200. The power manager 202 can have a power supply, which can be used to provide power to the entire handle 200. The air pump driver 203 can be used to drive the air pump 204 in response to the aforementioned preset drive signal. The air pump 204 can inflate the airbag 205 under the drive of the air pump driver 203, so that the airbag 205 is deformed to generate a force to provide tactile feedback to the user. At the same time, Fig.10 The circuit diagram of the air pump driver 203 in this embodiment is shown. Of course, the circuit design of the air pump driver 203 may not be limited to Fig.10 As shown. The wireless communication unit 206 can be used to receive and transmit electromagnetic wave signals to realize the wireless communication function of the handle 200. The sensor 207 may include an infrared sensor, a laser sensor, an inertial measurement sensor, etc., for detecting the user's proximity information, distance information, acceleration gyro information, and movement direction. The input unit 208 may include input devices such as the button 2121, the touch pad 2122, the joystick, and the trigger in the aforementioned embodiment, which can realize the interaction between the user and the handle 200. The memory 209 is used to store data instruction information (such as the control method in the aforementioned embodiment).

[0055] The handle 200 provided in the embodiment of the present application is provided with an airbag 220 on at least one of the gripping portion 211 and the touch-pressure portion 212 of the handle body 210, and the airbag 220 can be deformed multiple times under the control of the handle body 210, so that the handle 200 can use the force generated by the airbag 220 during the multiple deformation processes to provide the user with tactile feedback such as vibration, squeezing and friction, so as to improve the diversity of tactile feedback effects that can be provided when the handle 200 interacts with the user, thereby bringing the user a better tactile interaction experience.
