Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a head-mounted display device, a method and apparatus for adjusting the center of gravity of the head-mounted display device. Background Technology

[0002] With the proliferation of head-mounted displays (HMDs) applied to various fields such as virtual reality, augmented reality, and mixed reality, the pressure on the wearer's head, face, and cervical spine has gradually increased due to the increasing functionality and components of these devices. Many HMDs attempt to reduce facial pressure by placing components (such as batteries) at the back or separating them, or by adding forehead straps or weighted forehead masks to distribute pressure. All of these methods aim to improve comfort by altering the HMD's center of gravity.

[0003] While the above technologies effectively alleviate the pressure of head-mounted displays on the face, their fixed structure limits the applicable scenarios for users. For example, if the battery is placed at the back, users cannot use the device in a lying position. At the same time, the more parts of the device need to be in contact with the head and face, the more easily it is affected by differences in facial features. For example, adding a weight-bearing mask to the forehead or back of the head will affect the fit due to different head shapes, head circumferences, and other characteristics of users, thus affecting the load-bearing capacity of the accessories. Summary of the Invention

[0025] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0026] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] The following description, in conjunction with the accompanying drawings, details the head-mounted display device, the method for adjusting the center of gravity of the head-mounted display device, and the apparatus for doing so, through specific embodiments and application scenarios.

[0028] like Figure 1 As shown, this application embodiment provides a head-mounted display device, including:

[0029] Headset body A;

[0030] Back of the head (C);

[0031] Wearing component B connects the head-mounted display body A and the back pillow C;

[0032] A first accessory D is disposed on the wearing component B, and the first accessory D is movable on the wearing component; wherein, the first accessory D is an accessory other than the display module of the head-mounted display device. Optionally, the first accessory D is a battery.

[0033] Alternatively, the wearing component B may also be referred to as a headband or strap.

[0034] In this embodiment, a relatively heavy battery or other accessories (excluding the visible module) are mounted on the wearable component B, and their position can be freely adjusted. Optionally, the position of the first accessory can be determined by a sensor on the wearable component B.

[0035] It should be noted that the position of the first accessory can be adjusted manually by the user or controlled by the control module of the head-mounted display device; no specific limitation is made here.

[0036] In an optional embodiment of this application, the head-mounted display device further includes:

[0037] The headset is mounted on the wearing component and is movable on the wearing component.

[0038] The headset can be a wireless Bluetooth headset or a wired headset; if the headset is a wired headset, the wired headset cable is hidden inside the wearing component, and the length of the wired headset cable is adjustable.

[0039] For example, the head-mounted display headset is mounted on the wearing component via a locking component, and the locking component can move relative to the wearing component, thereby causing the head-mounted display headset to move.

[0040] In another optional embodiment of this application, the length of the wearing component is adjustable. Since different users have different head circumferences, in order to make the wearing component suitable for different users, the wearing component in this embodiment can achieve length adjustment through a telescopic structure or the like.

[0041] This application provides a head-mounted display device to address the user's needs for comfort and convenience when wearing the device. The first accessory of the head-mounted display device can be moved on the wearing component. By adjusting the position of the first accessory on the wearing component, the center of gravity of the head-mounted display device can be adjusted so that the center of gravity of the head-mounted display device is close to or coincides with the center of gravity of the user's head, thereby achieving the purpose of wearing comfort and improving the user experience.

[0042] To more clearly describe the head-mounted display device provided in the embodiments of this application, the method for adjusting the wearing center of gravity of the head-mounted display device will be described in detail below with reference to the accompanying drawings.

[0043] like Figure 2As shown in the figure, this application provides a method for adjusting the center of gravity of a head-mounted display device, wherein the head-mounted display device is as follows: Figure 1 The head-mounted display device, the method includes:

[0044] Step 201: After the user wears the head-mounted display device through the wearing component, if the distance between the user's head center of gravity and the head-mounted display device's center of gravity is greater than a first threshold, the distance between the user's head center of gravity and the head-mounted display device's center of gravity is less than or equal to the first threshold by moving the position of the first accessory on the wearing component.

[0045] Optionally, the first threshold can be equal to 0, or a value slightly greater than 0, without specific limitations. It should be noted that the closer the comfortable center of gravity of the head-mounted display is to the body's own center of gravity, or the smaller the overall center of gravity shift after wearing the head-mounted display, the greater the wearing comfort.

[0046] As an optional embodiment, step 201 includes:

[0047] After the user wears the head-mounted display device through the wearing component and lights up the head-mounted display body, the head-mounted display body displays a first interface; the content displayed on the first interface includes: the user's head outline, the head center of gravity position mark, the current position of the first accessory, the center of gravity position mark of the head-mounted display device when the first accessory is in the current position, and the area to be moved of the first accessory.

[0048] Control the first accessory to move to the area to be moved; or, respond to the user's movement operation and determine that the first accessory has moved to the area to be moved.

[0049] Specifically, when the first accessory moves into the area to be moved, the distance between the user's head center of gravity and the head-mounted display device's center of gravity is less than or equal to the first threshold.

[0050] like Figure 1 The image shows the content displayed on the first interface, where the center of gravity of the header is marked as... Figure 1 The center of gravity for comfort is located in the center of gravity, and the current position of the first component is... Figure 1 The position D of the accessory at this moment, and the position of the center of gravity of the head-mounted display device when the first accessory is in the current position are marked as follows. Figure 1 At this moment, the center of gravity is in the position of the first component, and the area to be moved is... Figure 1 The accessory can be moved to position D. Users can move the first accessory according to prompts to adjust the center of gravity of the head-mounted display, or the head-mounted display can control the movement of the first accessory to adjust its center of gravity.

[0051] Optionally, when the movement of the first accessory is performed by the user, the first accessory can be mounted on the wearing part by a locking component, and the locking component can move relative to the wearing part, thereby driving the first accessory to move.

[0052] Optionally, when the movement of the first configuration is controlled by the head-mounted display device, the wearing component may be provided with a guide rail and a motor controlled by the control module of the head-mounted display device; the first accessory is disposed on the guide rail and connected to the motor, and the control module drives the roller of the motor to move, thereby moving the first accessory on the guide rail, thereby realizing the position adjustment of the first accessory.

[0053] Optionally, in at least one alternative embodiment of this application, the method further includes:

[0054] The user's head circumference is determined based on the length of the wearing component when the user is wearing the head-mounted display device;

[0055] The position of the user's tragus is determined based on the position of the head-mounted headset and the user's head circumference.

[0056] The position of the user's head center of gravity is determined based on the position of the user's tragus point.

[0057] In one optional embodiment of this application, such as Figure 3 As shown, a literature review reveals that the center of gravity (COM) of the human head is... h The tragus point is located 23mm above and 9mm forward from OC1. For example, the user's head circumference can be measured by the length of the head-mounted display's components, and the position of the headset's headphones can be used to determine the tragus point's location; for instance, the center of the headset headphones can be determined as the tragus point, or the position can be determined by placing the tragus point 2mm above the center of the headset headphones. After obtaining the tragus point position, the user's head center of gravity is determined to be 23mm above and 9mm forward from OC1.

[0058] It should be noted that the specific values ​​mentioned above, such as 2mm, 23mm, 9mm, etc., can be adjusted according to the actual application; whether to increase or decrease them is not specifically limited here.

[0059] In this embodiment, the current center of gravity of the head-mounted display (HMD) is first calculated. Then, the current HMD is calculated by adjusting the position of the first accessory. The adjustment method for the first accessory is displayed on the first interface of the HMD, making the HMD's center of gravity close to or coincide with the user's head center of gravity, thereby achieving comfortable wearing. Furthermore, by calculating the HMD's center of gravity and displaying the adjustment method on the HMD's display interface, this embodiment efficiently guides the user to a comfortable position, improving the user experience.

[0060] To more clearly describe the wearing center of gravity adjustment method provided in the embodiments of this application, an example is given below, such as... Figure 4 As shown:

[0061] 1. Wearing the Headset: After the user puts on the headset and tightens the headband, the headset will calculate the position of the center of gravity based on the tightness of the headband. The center of gravity of the headset changes linearly with the tightness of the headband, so the system can preset the position of the headset's center of gravity corresponding to the headband's tightening position. At this time, the accessories should be in the initial position.

[0062] Center of gravity calculation: According to the torque formula Ma*La=Mb*Lb, Ma represents the torque on side a, La represents the torque from the center of gravity to side a, Mb represents the weight on side b, and Lb represents the torque on side b. For example... Figure 5 As shown, different levels of tightness for the user represent changes in L. Based on the torque formula mentioned above and the already determined weights of the head-mounted display and the backrest, the user's center of gravity position under different levels of tightness can be calculated.

[0063] 2. Booting up and entering the launcher (Android system desktop launcher) interface: After the user turns on the headset, they will enter the system launcher interface.

[0064] 3. At this point, the interface displays the user's current head outline and marks the position of the head's center of gravity;

[0065] 4. At this time, the interface also displays the virtual center of gravity of the head-mounted display, as well as the virtual image of the head-mounted display, the virtual image of the first accessory, and the adjustable accessories;

[0066] 5. At this time, the head-mounted display also shows the movable range of the first configuration based on the user's head center of gravity position. The user can move the first accessory according to the prompts to adjust the center of gravity.

[0067] 6. After the user moves the accessory to adjust the center of gravity, click OK to enter the Video See-Through (VST) settings of the head-mounted display.

[0068] In summary, this embodiment first calculates the current center of gravity of the head-mounted display device, then calculates the current center of gravity of the head-mounted display device by adjusting the position of the first accessory, and displays the adjustment method of the first accessory on the first interface of the head-mounted display body, so that the center of gravity of the head-mounted display device is close to or coincides with the center of gravity of the user's head, thereby achieving the purpose of wearing comfort. Furthermore, this embodiment, by calculating the center of gravity of the head-mounted display device and displaying the adjustment method on the display interface of the head-mounted display body, efficiently guides the user to wear it in a comfortable position, improving the user experience.

[0072] As an optional embodiment, the mobile module includes:

[0074] The movement submodule is used to control the first accessory to move to the area to be moved; or, in response to the user's movement operation, to determine that the first accessory has moved to the area to be moved.

[0075] Wherein, when the first accessory moves into the area to be moved, the distance between the center of gravity of the user's head and the center of gravity of the head-mounted display device is less than or equal to the first threshold.
