[0031] This application provides a smart glasses embodiment, which may include at least one of virtual reality (VR) glasses, augmented reality (AR) glasses, and mixed reality (MR) glasses. This application embodiment uses XR glasses as an example for illustration; other types of smart glasses can be described by analogy.

[0032] Reference Figure 1 The diagram shows a structural schematic of a smart glasses according to an embodiment of this application. Figure 2 This diagram illustrates the structure of another type of smart glasses described in an embodiment of this application. Figure 1 and Figure 2 As shown, the smart glasses may specifically include: an eyeglass frame 10, which may include a frame 100 and temples 101 connected to the frame 100; a lens 11, which is disposed on the frame 100 and has a first reflective part 110; and a camera 12, which shoots toward the first reflective part 110. The first reflective part 110 can be used to receive light from the human eye 20 and reflect the light to the camera 12. The camera 12 can be used to obtain an image of the human eye 20 based on the light reflected by the first reflective part 110.

[0033] In this embodiment, the lens 11 is provided with a first reflective part 110, which can receive light from the human eye 20 and reflect it to the camera 12. The camera 12 can then obtain an image of the human eye 20 based on the light reflected by the first reflective part 110. By using the first reflective part 110, the light propagation path from the human eye 20 to the camera 12 can be changed, allowing the camera 12 to achieve forward imaging of the human eye 20 without placing it directly in front of the user's eye 20. This avoids obstructing the user's eye 20 by placing the camera directly in front of it, thus improving the user experience of the smart glasses.

[0034] In practical applications, while a user wears the smart glasses, eye tracking can be achieved by acquiring real-time images of the user's eyes to enable various functions. For example, in AR applications, eye-tracking technology can achieve seamless interaction and a more natural user experience. For instance, users can switch applications by moving their eyes, greatly improving ease of use and naturalness.

[0035] In specific applications, the camera 12 can be connected to the eyeglass frame 10 by means of adhesive, snap-fit, or fastener connection. This application embodiment does not specifically limit the connection method of the camera 12 on the eyeglass frame 10. Moreover, the camera 12 can be connected to the nose pad 102 in the eyeglass frame 10, or it can be connected to the temple 101 of the eyeglass frame 10. This application embodiment does not specifically limit the connection position of the camera 12 on the eyeglass frame 10.

[0036] In practical applications, the eyeglass frame 10 can serve as the structural foundation of the smart glasses, supporting the lenses 11 and various electronic components. Specifically, the eyeglass frame 10 may include a frame 100 and temples 101 connected to the frame 100. The frame 100 is mainly used to mount the lenses 11, while the temples 101 can be placed on the user's ears to support the frame 100. Typically, the frame 100 and temples 101 can be made of materials with a certain strength, such as metal or plastic, to reliably support the lenses 11 and various electronic components.

[0037] Specifically, the lens 11 of the smart glasses may include at least one of aspherical lenses, spherical lenses, and Fresnel lenses.

[0038] In specific applications, those skilled in the art may select at least one of aspherical lenses, spherical lenses, and Fresnel lenses for the lens 11 in the embodiments of this application as needed. The embodiments of this application do not specifically limit this.

[0039] In this embodiment, a first reflective part 110 may be provided on the lens 11. The first reflective part 110 can be used to receive light from the human eye 20 and reflect the light to the camera 12. The camera 12 can be used to obtain an image of the human eye 20 based on the light reflected by the first reflective part 110. Even without placing the camera 12 directly in front of or near the human eye 20, the camera 12 can still receive light from the human eye 20 in a forward direction, achieving forward imaging of the user's human eye 20, which is beneficial for obtaining a high-quality human eye image. This avoids the camera 12 obstructing the human eye 20 and affecting the user's vision, thus improving the user experience of the smart glasses.

[0040] In some alternative embodiments of this application, such asFigure 1 and Figure 2 As shown, a nose pad 102 is provided on the frame 100. The nose pad 102 can be used to support the frame 100, distribute pressure, and ensure wearing stability and comfort. As a key component in the smart glasses that comes into contact with the bridge of the nose, the nose pad 102 is scientifically designed to help the lenses 11 maintain their optical position while adapting to different bridge of the nose structures. Figure 1 As shown, the camera 12 can be connected to the nose pad 102. Light from the user's eye 20 can be reflected by the first reflector 110 and projected onto the camera 12 on the nose pad 102, so that the camera 12 can obtain an image of the user's eye 20. Figure 2 As shown, the camera 12 can be connected to the temple 101. Light from the user's eye 20 can be reflected by the first reflector 110 and projected onto the camera 12 on the temple 101 so that the camera 12 can obtain the image of the user's eye 20.

[0041] It should be noted that, in specific applications, those skilled in the art can place the camera 12 on the frame 100, temple 101, or nose pad 102 according to actual needs. This application embodiment does not specifically limit the position of the camera 12 on the eyeglass frame 10.

[0042] Optionally, a second reflective portion may also be provided on the lens 11. The smart glasses further include a light source disposed on the eyeglass frame 10. The light source can project supplementary light onto the second reflective portion, so that the supplementary light is reflected by the second reflective portion and then directed towards the human eye 20 inside the lens 11. In specific applications, the light from the human eye 20 can include both visible light from the outside environment and the supplementary light emitted from the light source and reflected by the second reflective portion. The supplementary light can be used to compensate for the light in the shadow areas of the human eye 20, thereby improving the quality of the human eye image obtained by the camera.

[0043] In practical applications, since the supplementary light emitted by the light source needs to be reflected by the second reflector before it can be projected onto the user's eye 20, the light source can prevent direct illumination of the eye 20, ensuring the safety of the eye 20. Furthermore, the reflection of the supplementary light by the second reflector allows the supplementary light to shine more directly onto the eye 20, ensuring uniform illumination and low power consumption. In addition, the reflection by the second reflector increases the optical path length of the supplementary light from the light source to the eye 20, thus lowering the design requirements of the lighting system.

[0044] It should be noted that the light reflected by the first reflector 110 can be visible light from the ambient light, so the image of the human eye 20 obtained by the camera 12 is a visible light image. When the visible light in the ambient light is insufficient, a light source 12 can be provided in the smart eye, and a second reflector can be provided to supplement the light by reflecting the supplementary light emitted by the light source 12.

[0045] Optionally, the light source is an infrared light source, and correspondingly, the supplementary light emitted by the light source can be infrared light. Compared to visible light and other visible light sources, infrared light is safer, more concealed, and produces no light pollution, making it less likely to expose the location of the light source, and thus more suitable for scenarios where the smart glasses require concealed light sources. Moreover, compared to visible light sources, infrared light sources have lower power consumption and longer battery life.

[0046] It should be noted that the first reflective part 110 and the second reflective part can usually be two independent reflective structures. However, in certain specific situations, the second reflective part and the first reflective part 110 can also be shared. This application embodiment does not limit this.

[0047] Optionally, the first reflective portion 110 may include at least one of a reflective coating and a reflective lens. When the first reflective portion 110 is a reflective coating, it can be directly applied to the lens 11 by spraying or deposition, offering flexible layout options. Furthermore, the first reflective portion 110 occupies less space. When the first reflective portion 110 is a reflective lens, it can be connected to the lens 11 of the smart glasses via bonding, snap-fitting, or other connection methods. This application embodiment does not specifically limit the connection method of the reflective lens on the lens 11.

[0048] In specific applications, the lens 11 may include a first region and a second region disposed outside the first region. Visible light from the outer side of the lens 11 can pass through the first region and be projected onto the human eye 20, while the human eye 20 on the inner side of the lens 11 is opposite to the first region. Typically, the first region may be located at the center of the lens 11. When the user wears the smart glasses, the first region may be positioned opposite the user's human eye 20, allowing external visible light to be directly projected onto the user's human eye 20 through the first region on the lens 11. The region on the lens 11 other than the first region may be the second region. When the user wears the smart glasses, the second region may be offset from the user's human eye 20. Typically, the second region may surround the first region, but for some irregularly shaped lenses 11, the second region may also be disposed parallel to the first region, i.e., the second region may be disposed on one side of the outer periphery of the first region, for example, on the side near the temple 101 or the side near the nose pad 102. This application embodiment does not specifically limit the relative positions of the first region and the second region.

[0049] In some optional embodiments of this application, the first reflective portion 110 is disposed in the second region. Since the second region can be offset from the user's eye 20 when the user is wearing the smart glasses, disposing of the first reflective portion 110 in the second region can prevent the first reflective portion 110 from affecting the passage of visible light and obstructing the user's line of sight, thereby improving the user's visual experience.

[0050] In practical applications, since the obstruction of the user's line of sight by the first reflective part 110 in the second area is negligible, the requirements for the structure and connection method of the first reflective part 110 are relatively low. That is, the first reflective part 110 can be selected from either a reflective coating or a reflective lens according to actual needs, and the reflective coating can be an aluminum coating or a silver coating, etc. The selection method of the first reflective part 110 is quite flexible.

[0051] Optionally, the second reflective part can also be disposed in the second area to avoid obstructing the user's line of sight, thereby improving the user's visual experience.

[0052] In some alternative embodiments of this application, the first reflective portion 110 may also be disposed in the first region. The first reflective portion 110 can be used to reflect the supplementary light and allow the visible light to pass through. That is, the first reflective portion 110 can allow the visible light to pass through, avoiding obstruction of the user's line of sight. At the same time, it can also reflect the supplementary light from the human eye 20 and reflect it to the camera 12 to improve the imaging quality of the camera 12 for the human eye. Specifically, the frequency band of the supplementary light may be different from that of the visible light. For example, the supplementary light may be infrared light with a different frequency band than the visible light.

[0053] Specifically, when the first reflective portion 110 is disposed in the first region, the first reflective portion 110 may include a reflective coating disposed in the first region. The reflective coating may be a transparent conductive oxide (TCO) based coating (e.g., an antimony-doped tin oxide (ATO) sol-gel coating), a metal / resin composite structure coating (e.g., a resin-coated aluminum sheet coating), etc. By setting the material and thickness of the reflective coating, the reflective coating can possess the characteristic of both transmitting visible light and reflecting supplementary light.

[0054] Of course, when the first reflective part 110 is disposed in the first region, the first reflective part 110 can be a reflective coating directly disposed on the lens 11, or it can be implemented by disposing the reflective coating on a transparent carrier. By disposing the reflective coating on the transparent carrier and then connecting the transparent carrier to a suitable position in the first region, the layout flexibility of the first reflective part 110 can be further improved.

[0055] For example, the first reflective coating 110 and the second reflective coating may include an aluminum coating, a silver coating, a transparent conductive oxide (TCO) based coating (e.g., an antimony-doped tin oxide (ATO) sol-gel coating), a metal / resin composite structure coating (e.g., a resin-coated aluminum sheet coating), etc. The specific material of the reflective coating is not limited in the embodiments of this application.

[0056] In summary, the smart glasses described in this application embodiment may include at least the following advantages:

[0057] In this embodiment, the lens is provided with a first reflective portion, which can receive light from the human eye and reflect it to the camera. The camera can then obtain an image of the human eye based on the light reflected by the first reflective portion. By using the first reflective portion, the light propagation path from the human eye to the camera can be altered, allowing for forward imaging of the eye without placing the camera directly in front of it. This avoids obstructing the user's eye by placing the camera directly in front of it, thus improving the user experience of the smart glasses.
