Description

Technical Field

[0001] This utility model relates to the field of AR glasses technology, and in particular to an AR glasses testing device. Background Technology

[0002] With the continuous development of information technology, augmented reality (AR) technology has received much attention in recent years. Augmented reality is a technology that cleverly integrates virtual information with the real world. It simulates and applies computer-generated virtual information to the real world, with the two types of information complementing each other, thereby "enhancing" the real world.

[0003] As the mainstream display technology for AR glasses, the performance of optical waveguides significantly impacts the user experience. When ambient light passes through the diffraction grating of a diffractive waveguide, some wavelengths of ambient light will pass through the grating and enter the wearer's field of vision, causing the user to perceive rainbow-colored stripes. The appearance of rainbow stripes can affect the user's field of vision, and may even cause dizziness and eye strain, thus greatly reducing the user's wearing experience.

[0004] In related technologies, a jig is used to fix the diffractive waveguide, and a camera with a lens simulates the human eye to take a picture. The location of the rainbow pattern in the image is then observed, and the brightness of the rainbow pattern in the photo is measured. In reality, different users have different facial features and head shapes. When testing rainbow patterns, related technologies cannot humanely adjust the test conditions to the conditions under which the user actually wears AR glasses. Therefore, it is often difficult to evaluate the user's real experience of rainbow patterns after wearing AR glasses. If manual observation and evaluation are used, the labor cost is high, and it is impossible to record the rainbow pattern image in real time. Utility Model Content

[0005] In view of this, the present invention proposes an AR glasses testing device, which aims to solve at least one of the aforementioned technical problems. The AR glasses testing device can simulate the conditions under which a user wears AR glasses, and achieve a rainbow pattern test effect that is closer to the user's real experience.

[0006] The AR glasses testing device proposed in this utility model is used to support and test AR glasses under test. The AR glasses testing device includes: a head model body, including at least a face portion, wherein the eye area on the face is a hollow area, and the waveguide lens of the AR glasses is aligned with the hollow area; a nose model body, used to support the nose support of the AR glasses, the nose model body is connected to the face, and the highest point of the part of the nose model body that contacts the nose support is a first bearing point; an ear model body, used to support the temples of the AR glasses, the ear model body is connected to the side of the head model body, and the highest point of the part of the ear model body that contacts the temples is a second bearing point, and the first bearing point and the second bearing point are separated by a first preset distance along a first direction; and an image acquisition component, used to acquire an image formed by the light coupling area of ​​the AR glasses, the image acquisition component including a light-collecting side, the light-collecting side being aligned with the light coupling area of ​​the AR glasses.

[0007] As can be seen from the above technical solution, the AR glasses testing device proposed in this utility model, by placing the AR glasses on the AR glasses testing device and making the nose support contact the nose phantom and the temples contact the ear phantom, achieves a relatively stable position for the AR glasses. Simultaneously, the optical waveguide lens is aligned with the hollowed-out area, facilitating light to reach the optical waveguide lens and then couple out to the light-collecting side, allowing the image acquisition component to capture images. This facilitates recording the position and characteristics of the rainbow pattern, and also facilitates subsequent detection and analysis. Since the first bearing point and the second bearing point in this application have a first preset distance along the first direction, this first preset distance can simulate the height difference between the human ear and nose. This makes the way the AR glasses are fixed during the rainbow pattern testing process more closely resembles the conditions under which a user wears AR glasses, achieving a rainbow pattern test result that more closely resembles the user's real experience. This utility model eliminates the need for subjective human evaluation, reducing labor costs and enabling timely acquisition of images with rainbow patterns, resulting in more objective recording of the rainbow patterns.

[0008] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit the disclosure of the embodiments of this utility model. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0013] Where there is no conflict, the following embodiments and features can be combined with each other.

[0014] AR glasses are head-mounted devices. When ambient light passes through a diffraction grating, some wavelengths of ambient light will enter the wearer's eye area, causing the user to observe rainbow-colored stripes, or rainbow patterns. To detect rainbow patterns in AR glasses, the glasses need to be fixed in place, and light needs to be incident on the waveguide lens 71 of the AR glasses. By observing whether rainbow patterns exist at the eye area corresponding to the light coupling region, and by analyzing parameters such as the position, brightness, and area of ​​the rainbow patterns when they are present, the impact of rainbow patterns on the display performance of the AR glasses can be determined. This provides a basis for optimizing the structure of the diffraction grating of the diffraction waveguide.

[0015] In related technologies, during testing, light sources are placed at different pitch and azimuth angles, and a fixture is used to fix the diffractive waveguide. A camera with a lens simulates the human eye taking pictures and then observes the location of the rainbow pattern in the image. At the same time, the brightness of the rainbow pattern in the photo is measured. Although these fixtures can support and adjust the angle of AR glasses, they cannot accurately simulate the actual wearing conditions of AR glasses by users. Therefore, it is often difficult to evaluate the real experience of users feeling the rainbow pattern after wearing AR glasses.

[0016] Furthermore, if the rainbow pattern is observed and evaluated manually after the fixture is fixed, the labor cost is high and the rainbow pattern image cannot be recorded in real time.

[0017] In view of this, the present invention proposes an AR glasses testing device 100.

[0018] like Figure 1 and Figure 2 As shown, the AR glasses testing device 100 proposed in this utility model is used to support and test the AR glasses 700 to be tested. The AR glasses testing device 100 includes: a head model body 10, a nose model body 20, an ear model body 30, and an image acquisition component 40.

[0019] Combination Figure 1 and Figure 3As shown, the head model body 10 includes at least a face 11, with the eyes on the face 11 being a cutout area 111. When the AR glasses 700 is placed in the AR glasses testing device 100, the waveguide lens 71 of the AR glasses 700 is aligned with the cutout area 111. The face 11 here can be understood as the front of the head, showing one side of the facial features. This face 11 is a single, rigid unit, which can be used to connect with the ear mold 30 and the nose mold 20, and can also be used to add different hairstyles or hair accessories. The face 11 should have the contour features of the user's face; the face 11 can also simulate different face shapes for different designs. The shape of the cutout area 111 is not limited and can be any shape, but it must ensure that the area corresponding to the eyes of the head model body 10 does not block the light propagating there, so that light can propagate from the waveguide lens 71 of the AR glasses 700 to the image acquisition component 40. In this application, different hairstyles can be added to the upper part of the head model body 10 to simulate the user's occlusion of the overhead light source, thus more closely resembling the real experience of the user wearing AR glasses 700.

[0020] Combination Figure 3 , Figure 5 and Figure 6 As shown, the nose phantom 20 is used to support the nose support 72 of the AR glasses 700. The nose phantom 20 is connected to the face 11, as shown. Figure 5 and Figure 6 As shown, the highest point of the part where the nose phantom 20 contacts the nose support 72 is the first bearing point 22. The nose phantom 20 is used to simulate the user's nose. Nose phantoms 20 with different nose shapes are manufactured so as to simulate the influence of different nose shapes of the user on the position of the optical waveguide lens 71 of the AR glasses 700 relative to the human eye.

[0021] like Figure 1 and Figure 2 As shown, the ear mold body 30 is used to support, for example, Figure 3 The temples 73 and earmolds 30 of the AR glasses 700 shown are connected to the side of the headmold body 10. Please refer to [the image / reference]. Figure 5 and Figure 6 As shown, the highest point of the part where the earmold body 30 contacts the temple 73 is the second bearing point 32, and there is a first preset distance between the first bearing point 22 and the second bearing point 32 along a first direction. Exemplarily, the first direction is approximately consistent with the direction of gravity when the headmold body 10 is aligned along the direction of gravity. Exemplarily, the first direction is as follows: Figure 1 , Figure 2 , Figure 5 and Figure 6 The first direction is shown. At this time, the ear mold 30 and the nose mold 20 have a certain height difference in the first direction.

[0022] Furthermore, such as Figure 1 and Figure 2 As shown, the image acquisition component 40 is used to acquire images formed by the light output area of ​​the AR glasses 700. The image acquisition component 40 includes a light-collecting side 41, which is aligned with the light output area of ​​the AR glasses 700. It is understood that the light-collecting side 41 can collect light and image it, thereby facilitating the subsequent image formation by the image acquisition component 40. The image acquisition component 40 in this application is used to simulate the human eye's ability to collect light and form images, thus eliminating the need for human observation.

[0023] As can be seen from the above, the AR glasses testing device 100 proposed in this utility model fixes the AR glasses 700 in a relatively stable position by placing the AR glasses 700 on the AR glasses testing device 100, making the nose support 72 contact the nose mold 20, and making the temples 73 contact the ear mold 30. At the same time, the optical waveguide lens 71 is aligned with the hollow area 111, so that after the light shines on the optical waveguide lens 71, it is coupled out to the light-collecting side 41 through the optical waveguide lens 71, which facilitates the image acquisition component 40 to acquire the image, thereby facilitating the recording of the position and characteristics of the rainbow pattern with the image, and also facilitating subsequent detection and analysis.

[0024] Since the AR glasses testing device 100 of this application has a first preset distance between the first bearing point 22 and the second bearing point 32 along the first direction, the first preset distance can simulate the height difference between the human ear and nose. When the AR glasses 700 is fixed, it naturally forms a certain tilt angle due to the aforementioned height difference, especially relative to the light-receiving side 41. As a result, the position of the AR glasses 700 on the AR glasses testing device 100 of this application is closer to the specific wearing situation when the user wears the AR glasses 700. Therefore, in the process of testing rainbow patterns, the way the AR glasses 700 is fixed is closer to the conditions under which the user wears the AR glasses 700, thereby achieving the effect of the rainbow pattern test results being closer to the user's real experience.

[0025] In this invention, there is no need to rely on subjective evaluation by human eyes, reducing labor costs and enabling timely acquisition and more objective recording of images with rainbow patterns.

[0026] In some embodiments, in order to better simulate the position of the human eye relative to the waveguide lens 71 when the user is wearing AR glasses 700 and viewing a rainbow pattern, and to better simulate the state of the rainbow pattern viewed by the user while wearing AR glasses 700, the light-collecting side 41 is arranged in the eye box area of ​​AR glasses 700, such as the geometric center of the eye box, or the light-collecting side 41 is arranged in the optimal viewing position of the human eye relative to the waveguide lens 71 when wearing AR glasses 700, so that the light-collecting side 41 can simulate the state of light collection when the human eye is actually wearing AR glasses 700.

[0027] In some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the earmold body 30 includes at least one fixing part 31, which is detachably connected to the temple 73, so that the temple 73 can be easily fixed and removed, and the temple 73 can be prevented from moving when it is fixed.

[0028] In some embodiments, such as Figure 4 As shown, the fixing part 31 includes a slot 311, and the temple 73 engages with the slot 311. The slot 311 has a certain opening, facilitating the insertion of the temple 73 into the slot 311 or the removal of the temple 73 from the slot 311, making operation convenient. For example, in a specific embodiment, the slot 311 has openings in both the direction from the nose mold 20 to the face 11 and in the length extension direction of the ear mold 30, allowing the temple 73 to naturally position itself along its length when inserted into the slot 311.

[0029] In other embodiments, the fixing part 31 includes a socket (not shown), and the temple 73 is inserted into the socket. The socket has multiple walls around it, and the length direction of the socket is consistent with the extension direction of the temple 73. This allows the temple 73 to be inserted into the socket along its own length direction, and the insertion action of the temple 73 stops after the nose support 72 contacts the nose mold 20.

[0030] In some other embodiments, the fixing part 31 includes a protrusion (not shown in the figure), and the temple 73 is supported and cooperated with the protrusion. The protrusion can protrude upward along the first direction, or it can be a protrusion with a certain curvature that simulates the curvature of the human ear. Thus, after the temple 73 contacts the earmold 30, it has a larger contact area, and the contact is more natural, the fit is better, and it is closer to the real state of the temple 73 being worn on the human ear.

[0031] In some embodiments of this utility model, such as Figure 4 As shown, the fixing part 31 includes multiple parts, which are spaced apart along a first direction. The temple 73 is connected to different fixing parts 31 to form multiple different second bearing points 32. The multiple different second bearing points 32 are located in the same earmold 30, and the first preset distance between the different second bearing points 32 and the first bearing point 22 is different. In these embodiments, by supporting the temple 73 on different fixing parts 31, the rainbow pattern that can be observed on the waveguide lens 71 due to the different height differences of the nose and ear of different users can be simulated.

[0032] For example, in some specific embodiments, such as Figure 4As shown, the multiple fixing parts 31 are multiple slots 311. The slots 311 have the same orientation, but each has a certain height difference along the first direction, so that different temples 73 can be inserted into different slots 311 to form different second bearing points 32.

[0033] In some embodiments of this utility model, such as Figure 3 As shown, the earmold 30 includes a first earmold 301 and a second earmold 302, which are respectively connected to both sides of the headmold body 10. The distance between the first earmold 301 and the second earmold 302 and the line connecting the two second bearing points 32 formed by the two temples 73 and the first bearing point 22 is the same. That is, the first earmold 301 and the second earmold 302 are symmetrically arranged with respect to the nose mold 20, and the AR glasses testing device 100 of this application can be fixed to both temples 73 at the same time. Of course, in these embodiments, AR glasses 700 with only one temple 73 can also be supported. Specifically, one temple 73 is in contact with one of the earmolds 30 of this application, while the nose support 72 is in contact with the nose mold 20, thereby achieving a wearing effect similar to that of the AR glasses 700 of this type. In these embodiments, the two second bearing points 32 are located on both sides of the headmold body 10, that is, on the two earmolds 30 respectively.

[0034] In other embodiments of this application, such as Figure 3 As shown, the earmold body 30 includes a first earmold body 301 and a second earmold body 302, which are respectively connected to both sides of the head mold body 10; Figure 5 As shown, the first earmold 301 and the second earmold 302 are respectively connected to the two second bearing points 32 formed by the two temples 73, and the first bearing point 22 are at the same first preset distance. Therefore, the first earmold 301 and the second earmold 302 of this application have the same height difference relative to the nose mold 20 in the first direction, so that the AR glasses 700 can maintain balance and not tilt during the test. In a specific embodiment, the first earmold 301 and the second earmold 302 have the same structure and are symmetrically arranged on the head mold body 10 with respect to the nose mold 20.

[0035] In other embodiments of this application, the earmold 30 includes a first earmold 301 and a second earmold 302, which are respectively connected to both sides of the headmold body 10. The distances between the first earmold 301 and the second earmold 302 and the lines connecting the two second bearing points 32 formed by the two temples 73 and the first bearing point 22 are the same. Simultaneously, the first earmold 301 and the second earmold 302 are respectively connected to the first predetermined distances between the two second bearing points 32 formed by the two temples 73 and the first bearing point 22. These embodiments combine the effects of the aforementioned two types of embodiments, and will not be elaborated upon here.

[0036] In some embodiments of this application, such as Figure 5 As shown, the nose support 72 is a curved connecting part 721. The connecting part 721 is arranged corresponding to the hollow area 111 and the nose mold body 20. In other words, the connecting part 721 is located between the two optical waveguide lenses 71 of the AR glasses 700. The highest point of the connecting part 721 in contact with the nose mold body 20 is the first bearing point 22. At this time, the curved portion of the connecting part 721 fits more closely to the nose mold 20, and the center of the connecting part 721 is located on the symmetrical midline of the entire AR glasses 700. When the connecting part 721 directly contacts the nose mold 20, the highest point along the first direction can be formed in the contact area between the two, which is the first bearing point 22. A plane is drawn along the first and second directions with the first bearing point 22 as the center, and the second bearing point 32 is translated along the third direction to point A on the plane. The third direction is orthogonal to the first and second directions. The first bearing point 22 is translated along the second direction to point B directly below point A. Then the distance between A and B is the first preset distance, which facilitates the quantitative measurement of the first preset distance between the nose mold 20 and the ear mold 30 in the first direction. In a specific embodiment, such as Figure 3 As shown, the connecting part 721 here can refer to the middle part of the frame 74, and the connecting part 721 connects to the frame parts on both sides respectively.

[0037] In some embodiments of this utility model, such as Figure 6As shown, the nose support 72 consists of two nose pads 722, which are respectively supported on both sides of the nose mold 20. The two nose pads 722 contact the nose mold 20 and respectively form two first bearing points 22. The first preset distance between the two first bearing points 22 and the second bearing point 32 is the same. The direct contact between the two nose pads 722 and the nose mold 20 increases the contact area between the nose mold 20 and the nose support 72, thus simulating the actual wearing situation of the AR glasses 700 when the user's nose is in direct contact with the nose pads 722. The first preset distance between the two first bearing points 22 and the second bearing point 32 is the same, meaning the entire nose support 72 is stably positioned on the nose mold 20. When the central axis of the nose mold 20 is parallel to the direction of gravity, the line connecting the geometric centers of the two nose pads 722 is perpendicular to the direction of gravity. When the central axis of the nose mold 20 is parallel to a first direction, the line connecting the geometric centers of the two nose pads 722 is perpendicular to the first direction. In these embodiments, the connecting portion 721 of the aforementioned embodiments may also be present, but the connecting portion 721 does not contact the nose mold body 20. During quantitative measurement, a plane is drawn with the line connecting the two first bearing points 22 intersecting the first direction, and the second bearing point 32 is translated along a third direction (not shown) to point C on the plane. The third direction is orthogonal to the first and second directions. The first bearing point 22 is translated along the second direction to directly below point C, forming point D. The distance between C and D is then the first preset distance. At this time, the first preset distance between the two first bearing points 22 and the second bearing point 32 is equal.

[0038] In some embodiments of this invention, the image acquisition component 40 is selected from a luminance meter 42, a camera, and a mobile phone. These types of image acquisition components 40 can all acquire light from the light-coupled area and form an image, thus enabling timely recording of images with rainbow patterns as needed. The luminance meter 42 can capture images with varying brightness levels and further analyze the different brightness levels of the display area to determine the location of the rainbow patterns and their impact on the display effect. Both the camera and the mobile phone can directly capture color photographs, allowing for a direct visual observation of the location and size of the rainbow patterns.

[0039] In some embodiments, such as Figure 1 and Figure 2As shown, the image acquisition component 40 employs a luminance meter 42 or a camera. The AR glasses 700 have two optical waveguide lenses 71. The centers of the light-coupled areas of the two optical waveguide lenses 71 are at a second preset distance along a second direction. The light-collecting side of the luminance meter 42 or camera can move the second preset distance to acquire images formed by the two light-coupled areas respectively. The second direction forms an angle with the first direction. For example, the second direction here refers to the extension direction of the line connecting the geometric centers of the two eye-box areas corresponding to the design of the AR glasses 700, while the second preset distance refers to the distance between the geometric centers of the two eye-box areas. That is, the light-collecting side 41 of the luminance meter 42 or camera in this application measures the images at the geometric centers of the two eye-box areas respectively, thereby simulating the user's viewing experience of the rainbow pattern of the AR glasses 700 through both eyes. For example, the second direction here is perpendicular to the first direction. In this application, by adjusting the second preset distance, the real state of users with different interpupillary distances wearing the AR glasses 700 can be simulated. Furthermore, by adjusting the height of the light-collecting side 41 relative to the top of the nose phantom 20, the real state of users with different interpupillary heights wearing the AR glasses 700 can be simulated.

[0040] In other embodiments, the image acquisition component 40 uses two mobile phones. The centers of the light-collecting sides 41 of the two mobile phones are at a second preset distance along a second direction. The two mobile phones can simultaneously acquire images formed by the light-coupled areas of the two optical waveguide lenses 71. The second direction forms an angle with the first direction. The mobile phones are small and can be moved flexibly, so they can be placed at the geometric center of the two eye box areas corresponding to the two optical waveguide lenses 71. This position can also be understood as the eye point position, which facilitates simultaneous capture of images of the light-coupled areas of the AR glasses 700. This allows for real-time observation of the rainbow pattern appearing on the AR glasses 700 at the same moment, thus more closely resembling the real state of the rainbow pattern seen by the human eye when wearing the AR glasses 700. In these embodiments, the mobile phones can be fixed by setting a clamp, and the center of the camera lens of the mobile phone is located at the geometric center of the eye box area, thereby simulating the fixed position of the human eye relative to the optical waveguide lenses 71. This makes the rainbow pattern displayed in the image captured by the mobile phone more closely resemble the real rainbow pattern seen by the user when wearing the AR glasses 700.

[0041] In some embodiments of this utility model, the AR glasses testing device 100 further includes a light source 50, which is used to emit light to the optical waveguide lens 71 of the AR glasses 700, so that the light propagates onto the optical waveguide lens 71 and forms normal propagation or forms rainbow patterns.

[0042] In a further embodiment, the light source 50 here is natural light, that is, ambient light, such as light emitted by a lamp or screen in a living environment, or in a sunlight environment.

[0043] In other embodiments, the light source 50 is an artificial light source with an adjustable emission angle. The brightness of the artificial light source is adjustable and easy to control. The artificial light source 50 allows the entire AR glasses testing device 100 to be tested at night and makes the lighting conditions during testing more stable, thereby obtaining more quantitative test results. For example, the light source 50 can be a laser, emitting parallel light rays towards the optical waveguide lens 71; or, for example, the light source 50 can be a point light source, a strip light source, or a surface light source, specifically an LED array. By adjusting the emission angle, the display effect of the optical waveguide lens 71 under different directions and angles of light can be obtained, thereby capturing images with different rainbow patterns, more closely resembling the rainbow pattern observed by a user wearing AR glasses 700 when the angle relative to the light source 50 is constantly changed.

[0044] In some embodiments of this utility model, such as Figure 7 As shown, the AR glasses testing device 100 also includes a detection component 60, which is used to detect the features of rainbow patterns in the image acquired by the image acquisition component 40. The detection component 60 can use some algorithms to quantitatively evaluate the parameters of the rainbow patterns in the image, such as obtaining parameter information such as the brightness, area, and image region position of different rainbow patterns, thereby further optimizing the design of the AR glasses 700 through these parameters.

[0045] In this application, the head shape, hairstyle, etc., of the user group to be simulated can be determined, and a corresponding head model body 10 can be made; the nose bridge shape of the user group to be simulated can be determined, and a corresponding nose model body 20 can be made; the height difference between the nose and ears of the user group to be simulated when wearing AR glasses 700 can be determined, and a fixing part 31 of the ear model body 30 can be made, which can simulate the effect of users wearing glasses with different ear positions. By adjusting the position of the luminance meter 42, the actual position of the human eye when users with different interpupillary distances and pupil heights wear glasses can be simulated.

[0046] In this application, the specific testing method when using the AR glasses testing device 100 is as follows: design each fixture according to the user model to be tested, place the AR glasses 700, adjust the luminance meter 42, place the fixture under the lighting conditions to be simulated, take a picture using the luminance meter 42, and then obtain a rainbow pattern image that closely approximates the subjective experience of the corresponding user model under these conditions.

[0047] In this application, a specific model was used, combined with replaceable parts of the model, to accurately test the rainbow effect of AR glasses 700 under specified ambient light conditions and user head shape, which is closest to the subjective feeling of humans.

[0048] In addition, the AR glasses testing device 100 of this application has a certain degree of compatibility, and can compare and test the rainbow effect of various AR glasses 700 under the same standard; it can also simulate the testing of rainbow patterns by users with different face shapes and facial features under different ambient light conditions.

[0049] In summary, the AR glasses testing device 100 of the present invention can effectively support the AR glasses 700, test the rainbow pattern of the AR glasses 700, and accurately simulate the rainbow pattern seen by the user when actually wearing the AR glasses 700. This enhances the human-centered design of the AR glasses 700, and the excellent rainbow pattern control makes the wearing experience of the AR glasses 700 closer to that of ordinary glasses, thereby increasing user satisfaction with the improved AR glasses 700.
