[0041] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0042] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0043] Technologies and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such technologies and equipment should be considered part of the specification.

[0044] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0045] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0046] This application provides a head shell. This head shell is specifically designed for use in testing devices for AR (Augmented Reality) / VR (Virtual Reality) / MR (Mixed Reality) head-mounted displays. Specifically, refer to... Figures 2-5 This testing device also integrates a testing device 5 that simulates a human eye, wherein at least a portion of the device, such as a human-eye-like camera 51, is housed inside the head shell. Through the collaborative operation of the head shell and the testing device 5 that simulates a human eye, the experience scenarios of different wearers when actually wearing a head-mounted display can be simulated, thereby significantly improving the accuracy and realism of the testing device's image analysis.

[0047] Reference Figure 1 The head shell includes: head shell body 1, ear device 2, nose device 3, and base 4.

[0048] The base 4 is provided with a connecting post 41 extending vertically, and the head shell body 1 is detachably mounted on the connecting post 41. The ear device 2 is detachably mounted on the base 4 and located to the side of the head shell body 1. The nose device 3 is detachably mounted on the base 4 and the head shell body 1.

[0049] In the embodiments of this application, reference is made to Figure 1 The head shell mainly includes the head shell body 1, ear device 2, nose device 3, and base 4. The base 4 serves as a supporting component for the head shell, supporting the head shell body 1, ear device 2, and nose device 3. The base 4 also supports the testing equipment 5 described later, which facilitates the assembly and disassembly of the head shell, as well as the assembly and disassembly of the testing equipment containing the head shell.

[0050] Furthermore, the head shell features a modular design, allowing for replacement as needed, thus enhancing its flexibility and scalability. For example, different sizes of the head shell body 1, and / or different sizes of the ear devices 2, and / or different sizes of the nose device 3 can be used to simulate the head structures of different wearers. This head shell is then applied to a testing device that simulates the experience of different wearers when actually wearing a head-mounted display, allowing for the analysis of image quality for different users.

[0051] Specifically, refer to Figure 4 The base 4 serves as the support structure for the head shell, and is provided with connecting posts 41 extending vertically (in the direction of gravity, i.e., from top to bottom or bottom to top). The main function of the connecting posts 41 is to provide stable and reliable support points for fixing the head shell body 1 to it. Exemplarily, the number of connecting posts 41 can be one or more. Placing the head shell body 1 on multiple connecting posts 41 can improve the installation stability of the head shell body 1. (Refer to...) Figure 4 The arrow indicates the vertical direction.

[0052] Reference Figure 1 and Figure 5 The head shell body 1 is detachably mounted on the connecting post 41, making it convenient for operators to replace the head shell body 1. Exemplarily, the detachable connection between the head shell body 1 and the connecting post 41 can be achieved by, but is not limited to, the following methods: screw fixing, snap-fit ​​connection, magnetic connection, or slot connection.

[0053] For example, the overall shape of the head shell body 1 is designed to closely resemble the contour of a real human head to ensure the accuracy and authenticity of the image analysis by the testing device.

[0054] For example, the material of the head shell body 1 can be a lightweight metal such as aluminum alloy, a plastic such as ABS, nylon, foam, or composite material.

[0055] Ear device 2 simulates the appearance of the wearer's ear, for reference Figure 3 The head shell includes two ear devices 2, which are located on the sides of the head shell body 1. The AR / VR / MR head-mounted display can be hung on the head shell to simulate the scenario of the wearer wearing the AR / VR / MR head-mounted display.

[0056] The ear device 2 can be detachably mounted on the base 4 using screws or bolts, clips, or magnetic attachment. Because the ear device 2 is detachable, operators can replace it with different sizes or styles as needed.

[0057] Reference Figures 1-3 and Figure 5The nose device 3 can be detachably mounted on the base 4 and the head shell body 1 by means of embedding or fastener fixation. For example, a part of the nose device 3 can be detachably mounted on the base 4, and another part of the nose device 3 can be detachably mounted on the head shell body 1. For example, the structure of the nose device 3 mounted on the base 4 can be a liner 32.

[0058] For example, the head shell body 1 forms a hollow part corresponding to the installation position of another part of the nose device 3, so that the nose device 3 can abut against the liner 32. This design makes the head shell structure more realistic and conforms to the wearer's head structure.

[0059] Therefore, in this embodiment, the head shell is assembled from four modules: head shell body 1, ear device 2, nose device 3, and base 4, forming a complete and realistic head model. Operators can disassemble or replace modules according to actual needs (the specific structure of the wearer's head) to simulate the experience of different wearers when actually wearing a head-mounted display, thereby improving the universality of the head shell.

[0060] In one specific embodiment, refer to Figure 1 , Figure 2 and Figure 5 The end of the connecting post 41 facing away from the base 4 is provided with a first mating part, and the head shell body 1 is provided with a second mating part inside. The first mating part and the second mating part are connected so that the head shell body 1 is detachably mounted on the connecting post 41.

[0061] In this embodiment, a first mating part is provided at the end of the connecting post 41 away from the base 4 (i.e., the top of the connecting post 41). The shape, size and position of the first mating part match the second mating part. The second mating part and the first mating part work together to securely mount the head shell body 1 on the connecting post 41.

[0062] For example, the first mating part can be one of the protrusions or recesses provided at the end of the connecting post 41, and the second mating part can be another of the protrusions or recesses provided inside the head shell body 1, so that the head shell body 1 and the connecting post 41 are connected by a slot.

[0063] For example, the first mating part can be a first magnetic component, and the second mating part can be a second magnetic component, so that the head shell body 1 and the connecting post 41 are connected by magnetic attraction.

[0064] It should be noted that the structure of the first mating part and the second mating part is not particularly limited in this embodiment, as long as the head shell body 1 can be detachably mounted on the connecting post 41.

[0065] In a preferred embodiment, refer to Figure 4The connecting column 41 is located in the middle region of the base 4.

[0066] In this embodiment, placing the connecting post 41 in the central region of the base 4 ensures the stability of the head shell body 1 on the base 4. Because the connecting post 41 is located at the center of the base 4, it provides uniform support, preventing the head shell body 1 from tilting or wobbling under external forces. Furthermore, the central location allows for a more balanced distribution of the head shell body 1 on the base 4. This helps reduce the risk of deformation or damage to the head shell during long-term use, thereby extending its service life.

[0067] In one specific embodiment, refer to Figures 1-3 The nose device 3 includes a liner 32 and a nose body 31. The liner 32 is embedded in the end face of the base 4 and is at least partially located inside the head shell body 1. Exemplarily, the end face of the base 4 (which is the front end face of the base 4) forms a recess, and the liner 32 is embedded in the recess. The operator can replace the liner 32 with one of different structure or size according to the size or style of the nose body 31.

[0068] The liner 32 serves as a support and fixing structure for the nose body 31, ensuring that the nose body 31 can be stably installed on the head shell body 1. The nose body 31 is detachably mounted on the head shell body 1 using methods such as screws, clips, or magnets, and abuts against the liner 32. The nose body 31 is located at the front end of the head shell body 1, simulating the position and shape of a real nose.

[0069] In one specific embodiment, refer to Figure 4 and Figure 5 The ear device 2 includes an ear module and a connecting component 23. The ear module is disposed on the connecting component 23. The base 4 is provided with a mounting groove 42, and the connecting component 23 is embedded in the mounting groove 42.

[0070] In this embodiment, the ear module is the main part that simulates the appearance of the wearer's ear, and at least part of the ear module is made of a soft material (such as foam, rubber, or silicone). The connecting component 23 is the connection between the ear module and the base 4. The connecting component 23 can be made of a strong and durable material to ensure that the ear module is securely fixed to the base 4. The design of the connecting component 23 may include slots, clips, screws, or other detachable connection structures so that an operator can easily install or remove the ear module.

[0071] Furthermore, a mounting groove 42 is provided on the base 4 to accommodate the connecting component 23, through which the ear device 2 is mounted on the base 4. The shape and size of the mounting groove 42 match those of the connecting component 23 to ensure that the connecting component 23 can be securely embedded within the mounting groove 42. This design not only provides stable support but also prevents the ear device 2 from loosening or falling off during use.

[0072] In a more specific embodiment, refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The ear module includes a first drive module 21, a second drive module 22, and an ear assembly 20. The ear assembly 20 is disposed on the first drive module 21, and the first drive module 21 drives the ear assembly 20 to move vertically. The first drive module 21 is disposed on the second drive module 22 via the connecting component 23, and the second drive module 22 drives the ear assembly 20 to move horizontally.

[0073] In this embodiment, the connecting component 23 connects the first drive module 21 and the second drive module 22 together. At the same time, the connecting component 23 is also responsible for embedding the ear module as a whole into the mounting groove 42 of the base 4, ensuring that the ear device 2 can be firmly fixed on the head shell.

[0074] In addition, refer to Figure 5 To more precisely control the vertical movement of the ear assembly 20, a first scale mark 234 is provided on the connecting component 23. By reading the value on the scale mark, the operator can accurately understand the current position and height information of the ear assembly 20, thereby achieving precise control of the first drive module 21 and the second drive module 22.

[0075] For example, refer to Figure 4 and Figure 5 The connecting component 23 may include a first connecting plate 231, a second connecting plate 232, and a third connecting plate 233. The first connecting plate 231, the second connecting plate 232, and the third connecting plate 233 are integral structural components or connected together by some kind of fastening method.

[0076] The first drive module 21 is directly mounted on the first connecting plate 231, and the first scale mark 234 is mounted on the first connecting plate 231. The second connecting plate 232 is directly mounted on the second drive module 22, and the third connecting plate 233 is used to mount the entire ear device 2 on the base 4.

[0077] The specific structures of the first drive module 21, the second drive module 22, and the ear assembly 20 are described below:

[0078] Reference Figure 4 and Figure 5 The ear assembly 20 includes a first mounting portion 201, a second mounting portion 202, and an ear body 203. The ear body 203 is disposed on the second mounting portion 202. The first mounting portion 201 is mounted on and driven by the first drive module 21, and the first mounting portion 201 drives the ear body 203 to move in the vertical direction.

[0079] Reference Figure 5 The connection between the second mounting part 202 and the first mounting part 201 adopts a detachable design. This design not only facilitates the assembly and disassembly of the ear assembly 20, but also gives the ear device 2 flexibility and adjustability.

[0080] For example, by simply replacing or adjusting the second mounting part 202 and the ear body 203 thereon, it is easy to adapt to the ear shape and size of different wearers, thereby further improving the accuracy and realism of image analysis.

[0081] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The first drive module 21 includes a first drive unit 210 and a first transmission unit 211, with the ear assembly 20 disposed on the first transmission unit 211; the first drive unit 210 drives the first transmission unit 211 to rotate, and the first transmission unit 211 drives the ear assembly 20 to move vertically. Figure 1 and Figure 4 As shown, the vertical direction is indicated.

[0082] Under the coordinated action of the first drive unit 210 and the first transmission unit 211, the first drive module 21 drives the ear assembly 20 to move in the vertical direction.

[0083] The first drive unit 210 serves as the power source for the first drive module 21. The first drive unit 210 can be driven manually or electrically, with the electrical drive employing a motor, hydraulic pressure, or pneumatic drive method.

[0084] The first transmission unit 211 transmits the driving force generated by the first drive unit 210 to the ear assembly 20. To enable vertical movement of the ear assembly 20, the first transmission unit 211 can be designed to rotate about a certain axis. For example, the first transmission unit 211 can specifically be a screw, lead screw, or similar structure.

[0085] In one specific embodiment, refer to Figure 4The first mounting part 201 is disposed on the first transmission part 211, and the ear body 203 is disposed on the first mounting part 201 via the second mounting part 202. When the first transmission part 211 rotates, the first mounting part 201 moves vertically, and the first mounting part 201 drives the ear body 203 to move vertically. This design not only ensures that the ear assembly 20 can accurately simulate the ear position of different wearers, but also makes the headgear more versatile.

[0086] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The second drive module 22 includes a second drive section 220 and a second transmission section 221. The first drive module 21 is disposed on the second transmission section 221. The second drive section 220 drives the second transmission section 221 to rotate, and the second transmission section 221 drives the ear assembly 20 to move horizontally. Figure 1 and Figure 4 This indicates the horizontal direction.

[0087] Under the coordinated action of the second drive unit 220 and the second transmission unit 221, the second drive module 22 drives the ear assembly 20 to move in the horizontal direction.

[0088] The second drive unit 220 serves as the power source for the second drive module 22. The second drive unit 220 can be driven manually or electrically. The electrical drive can be achieved using a motor, hydraulic system, or pneumatic system to ensure efficient and stable power output.

[0089] The second transmission unit 221 transmits the driving force generated by the second drive unit 220 to the first drive module 21. Specifically, the second drive unit 220 directly drives the connecting component 23 to move, thereby the connecting component 23 drives the first drive module 21 and the ear component 20 to move.

[0090] To enable the first drive module 21 to move horizontally, the second transmission unit 221 is designed to rotate about a certain axis. For example, the second transmission unit 221 can be a screw or lead screw, etc. This not only ensures that the ear assembly 20 can accurately simulate the natural position of different wearers' ears, but also provides sufficient stability and reliability to meet the needs of long-term testing.

[0091] In addition, refer to Figure 1 The second drive module 22 also includes a first fixing part 241 and a second fixing part 242 arranged at intervals along the horizontal direction. These two fixing parts specifically provide a stable mounting platform for the second transmission part 221.

[0092] One end of the second transmission unit 221 is fixed to the first fixing part 241, while the other end passes through the second fixing part 242 and is reliably connected to the second drive unit 220. This design not only ensures that the second transmission unit 221 can rotate smoothly, but also guarantees its stability and accuracy during rotation.

[0093] In a further embodiment, referring to Figure 1 The second drive module 22 also includes a connector 243. One end of the connector 243 is connected to the first fixing part 241, and the other end of the connector 243 is connected to the second fixing part 242. A second scale mark 244 is provided on the connector 243.

[0094] This application also provides a testing apparatus. (Refer to...) Figures 2-5 The testing apparatus includes a head shell as described above and a testing device 5 simulating a human eye, at least a portion of which is located inside the head shell.

[0095] In this embodiment, the head shell is applied to the testing device, which can simulate the experience scenarios of different wearers when actually wearing a head-mounted display, analyze the image quality of different wearers wearing the head-mounted display, and improve the accuracy and authenticity of image analysis.

[0096] In one embodiment, refer to Figure 4 and Figure 5 The testing device includes two human-eye-like cameras 51 and a base 52. The two human-eye-like cameras 51 are spaced apart on the base 52, and the base 52 is disposed on the base 4.

[0097] In this embodiment, the testing device mainly consists of two human-eye-like cameras 51 and a base 52. The two human-eye-like cameras 51 are mounted on the base 52, enabling the testing device to perform omnidirectional and multi-angle image analysis of the target image.

[0098] The human-eye-like camera 51, as the core component of the testing device, simulates the wearer's binocular visual system. This camera 51 can acquire images displayed in AR / VR / MR environments, and the testing device analyzes the quality of these images.

[0099] The base 52 is the support structure of the testing equipment, used to fix and support the two human-eye-like cameras 51. The base 4 also serves as a support structure for the testing equipment, used to fix and support the base 52. The base 4 is typically designed to be robust and stable to ensure the stability of the testing equipment during use.

[0100] For example, the connecting post 41 is located in the middle region of the base 4, and the head shell body 1 is detachably mounted on the connecting post 41. The ear device 2 is located in the first region of the base 4, and the testing device 5 simulating the human eye is located in the second region of the base 4. The second region and the first region are located on opposite sides of the middle region, with the first region located behind the middle region and the second region located in front of the middle region, thereby improving the fit between the overall structure of the head shell and the wearer's head structure.

[0101] For example, refer to Figure 4 and Figure 5 The cone-shaped structure shown in front of the human-eye camera 51 represents the field of view of the light emitted from the human-eye camera 51, and is not a physical structure of the test device. As can be seen from the field of view in the figure, there is no structural interference within the test device, and therefore it does not affect the field of view of the human-eye camera 51.

[0102] In one embodiment, refer to Figure 4 and Figure 5 The base 52 is provided with an adjustment component (not shown), which is used to adjust the distance between the two human-eye-like cameras 51 in a first direction, wherein the first direction, the vertical direction and the horizontal direction are perpendicular to each other.

[0103] In this embodiment, this design allows us to adjust the distance between the two human-eye cameras 51 by adjusting the components according to the test requirements (simulating the interpupillary distance between different wearers), so that the test device can simulate the wearing effect of different wearers when actually wearing a head-mounted display.

[0104] For example, based on the movement distance of the two human-eye cameras 51 in the first direction, the area on the head shell body 1 corresponding to the human-eye cameras 51 is a racetrack-shaped through hole.

[0105] It should be noted that the structure of the adjustment component is not limited in this embodiment, as long as it can adjust the distance between the two human eye-like cameras 51 in the first direction.

[0106] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.

[0107] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application. The scope of this application is defined by the appended claims.
