Description

Technical Field

[0001] This application belongs to the field of electronic device technology, specifically relating to a smart pair of glasses. Background Technology

[0002] As users increasingly demand the best user experience, their requirements for the performance of wearable devices such as smart glasses are also rising, leading to a proliferation of functionalities in smart glasses. For example, smart glasses can be equipped with eye-tracking cameras to achieve eye tracking, gaze detection, and iris recognition, further enhancing the ease of use and user experience.

[0003] In existing technologies, during the eye detection process using an eye-tracking camera, supplemental lighting is typically required to improve the detection results in the eye area. Current supplemental lighting solutions usually involve directly illuminating the eye area with a light source, which obstructs the view of the eye and affects the user experience. Moreover, since the light directly illuminating the eye area is usually at an angle, the light utilization rate is low and the image quality is poor. Utility Model Content

[0004] This application aims to provide a smart glasses solution to address the problems of low light utilization efficiency and poor image quality in existing smart glasses.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0007] An eyeglass frame, the eyeglass frame including a frame and temples connected to the frame;

[0008] A lens, wherein the lens is disposed on the lens frame and the lens is provided with a reflective portion;

[0009] The light source is disposed on the lens frame and is used to project supplementary light onto the reflective part so that the supplementary light is reflected by the reflective part and then directed toward the human eye inside the lens.

[0010] Optionally, the reflective portion includes at least one of a reflective coating and a reflective lens.

[0011] Optionally, the lens includes a first region and a second region disposed outside the first region, visible light from the outer side of the lens passes through the first region and is directed toward the human eye, and the human eye from the inner side of the lens is opposite to the first region.

[0013] Optionally, the reflective portion is disposed in the first region, and the reflective portion is used to reflect the supplementary light and allow the visible light to pass through.

[0017] Optionally, the camera's shooting direction is towards the reflective part, which receives light from the human eye and reflects the light back to the camera. The camera then obtains an image of the human eye based on the light reflected by the reflective part.

[0018] Optionally, the frame is provided with a nose pad, and the light source is connected to the nose pad or the temple.

[0019] Optionally, the light source (12) is an infrared light source.

[0020] In this embodiment, the lens is provided with a reflective portion, which can reflect the supplementary light emitted by the light source to the human eye within the lens, thereby assisting in image formation. This avoids the light source directly obstructing the human eye, improving the user experience of the smart glasses. Furthermore, the reflection by the reflective portion extends the path of the supplementary light and adjusts the angle at which it illuminates the human eye, resulting in more uniform illumination, improved image quality, increased light efficiency, and reduced overall power consumption of the smart glasses.

[0030] 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.

[0031] 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: a glasses 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 reflective part 110; and a light source 12, which is disposed on the frame 100 and can be used to project supplementary light onto the reflective part 110, so that the supplementary light is reflected by the reflective part 110 and then directed toward the human eye 20 inside the lens 11.

[0032] In this embodiment, the lens 11 is provided with a reflective portion 110, which can reflect the supplementary light emitted by the light source 12 to the human eye 20 within the lens 11, thereby assisting in imaging the human eye 20. This avoids the light source 12 directly obstructing the human eye 20 when it is directly projected onto it, improving the user experience of the smart glasses. Furthermore, the reflection by the reflective portion 110 extends the path of the supplementary light and adjusts the angle at which it illuminates the human eye 20, resulting in more uniform illumination, improved imaging quality, increased light efficiency, and reduced overall power consumption of the smart glasses.

[0033] 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.

[0034] Specifically, the lens 11 of the smart glasses may include at least one of aspherical lenses, spherical lenses, and Fresnel lenses.

[0035] Generally, aspherical lenses are flatter, thinner, and provide a more realistic view than spherical lenses. Most smart glasses use aspherical lenses to more accurately reproduce the world we see without localized distortion. Spherical lenses, on the other hand, produce slight distortion of objects at the edges of the field of vision. This is the most important difference between the two.

[0036] Fresnel lenses, also known as threaded lenses, have the same curvature (the rate of rotation of the tangent angle about the arc length at a point on a curve, defined by differentiation, indicating the degree to which the curve deviates from a straight line; mathematically, it represents the degree of curvature of the curve at a point. The greater the curvature, the greater the curvature of the curve) as ordinary lenses, but their surface is engraved with threads of varying sizes. Current smart glasses typically use Fresnel lenses, which are thinner and lighter. Lenses with more threads produce a clearer image, affecting curvature and light focusing, while lenses with fewer threads affect sharpness.

[0037] 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.

[0038] In this embodiment, a reflective portion 110 may be provided on the lens 11, which can be used to reflect supplementary lighting light. Specifically, the light source 12 can emit supplementary lighting light to the reflective portion 110, which can be either infrared light or white light. After the light source 12 projects the supplementary lighting light onto the reflective portion 110, the reflective portion 110 can reflect the supplementary lighting light to the human eye 20 behind the lens 11, thereby providing supplementary lighting to the user's eye area. This facilitates obtaining higher quality images of the human eye 20 when photographing it.

[0039] In practical applications, since the supplementary light emitted by the light source 12 needs to be reflected by the reflector 110 before it can be projected onto the user's eye 20, the light source 12 can prevent direct illumination of the eye 20, ensuring the safety of the eye 20. Furthermore, the reflection of the supplementary light by the reflector 110 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 reflector 110 increases the optical path length of the supplementary light from the light source 12 to the eye 20, thus lowering the design requirements of the lighting system.

[0040] In some alternative embodiments of this application, such as Figure 1 and Figure 2As 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 light source 12 can be connected to the nose pad 102. The supplementary light emitted from the light source 12 on the nose pad 102 can be projected onto the reflective part 110 on the lens 11 and reflected by the reflective part 110 to the human eye 20 to provide supplementary lighting for the human eye area. Figure 2 As shown, the light source 12 can be connected to the temple 101. The supplementary light emitted from the light source 12 on the temple 101 can be projected onto the reflective part 110 on the lens 11 and reflected by the reflective part 110 to the human eye 20 to provide supplementary light to the human eye area.

[0041] It should be noted that, in specific applications, those skilled in the art can place the light source 12 on the frame 100 or the temple 101 according to actual needs. In this embodiment, the position of the light source 12 on the eyeglass frame 10 is not specifically limited.

[0042] Optionally, the light source 12 is an infrared light source, and correspondingly, the supplementary light emitted by the light source 12 can be infrared light. Compared with visible light such as white light supplementary light, infrared light has the characteristics of being safe, concealed, and free of light pollution, making it less likely to expose the location of the light source 12, and is more suitable for scenarios where the smart glasses require concealed light source 12. Moreover, compared with white light sources, infrared light sources have lower power consumption and longer battery life.

[0043] In this embodiment, the smart glasses may further include a camera connected to the frame 100, which can be used to acquire images of the user's eyes 20. In specific applications, by acquiring real-time images of the user's eyes while the user wears the smart glasses, eye tracking can be achieved to enable various functions. For example, in the field of ophthalmology, eye tracking allows for rapid and comprehensive vision checks, improving efficiency and convenience. Furthermore, in VR applications, eye tracking technology enables seamless interaction and a more natural user experience. Users can switch applications by moving their eyes or zoom in / out of virtual interfaces with gestures, greatly enhancing ease of use and naturalness.

[0044] In specific applications, the camera is connected to the eyeglass frame 10 by means of adhesive, snap-fit, or fastener connection. This embodiment does not specifically limit the connection method of the camera on the frame 100. Furthermore, the camera can be connected to the frame 100 or the temple 101 of the eyeglass frame 10. This embodiment does not specifically limit the connection position of the camera on the eyeglass frame 10.

[0045] Optionally, the camera's shooting direction is towards the reflector 110. The reflector 110 can receive light from the human eye 20 and reflect the light back to the camera. The camera can then obtain an image of the human eye 20 based on the light reflected by the reflector 110. In specific applications, the light from the human eye 20 can include both visible light from the outside world and the supplementary lighting emitted from the light source 12 and reflected by the reflector 110. The supplementary lighting 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.

[0046] Optionally, the reflective portion 110 may include at least one of a reflective coating and a reflective lens. When the reflective portion 110 is a reflective coating, it can be directly applied to the lens 11 by spraying or deposition, offering flexible layout options and occupying less space. When the reflective portion 110 is a reflective lens 11, 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 11 to the lens 11.

[0047] 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 be arranged around the first region, but for some irregularly shaped lenses 11, the second region may also be arranged parallel to the first region. This application embodiment does not specifically limit the relative positions of the first region and the second region.

[0048] In some optional embodiments of this application, the 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 reflective portion 110 in the second region can prevent the 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.

[0049] In practical applications, since the obstruction of the user's line of sight by the reflective part 110 in the second area is negligible, the requirements for the structure and connection method of the reflective part 110 itself are relatively low. That is, the reflective part 110 can be selected from either a reflective coating or a reflective lens according to actual needs, and the selection method of the reflective part 110 is quite flexible.

[0050] In some alternative embodiments of this application, the reflective portion 110 is disposed in the first region. The reflective portion 110 can reflect the supplementary light and allow the visible light to pass through. That is, the reflective portion 110 can both allow the visible light to pass through, avoiding obstruction of the user's line of sight, and reflect the supplementary light emitted by the light source 12 to the user's eye 20 position, improving the brightness uniformity at the eye 20 position. For example, when the light emitted by the light source 12 is infrared light, the reflective portion 110 disposed in the first region needs to both allow the visible light to pass through and reflect the infrared light.

[0051] Specifically, when the reflective part 110 is disposed in the first region, the reflective part 110 may include a reflective coating disposed in the first region. By setting the material and thickness of the reflective coating, the reflective coating can have the characteristic of both transmitting visible light and reflecting supplementary light.

[0052] Of course, when the reflective part 110 is disposed in the first region, the 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 reflective part 110 can be further improved.

[0053] For example, the reflective coating may include at least one of an aluminum coating and a silver coating. In this embodiment of the application, the specific material of the reflective coating is not limited.

[0054] In summary, the smart glasses described in this application embodiment may include at least the following advantages:

[0055] In this embodiment, the lens is provided with a reflective portion, which can reflect the supplementary light emitted by the light source to the human eye within the lens, thereby assisting in image formation. This avoids the light source directly obstructing the human eye, improving the user experience of the smart glasses. Furthermore, the reflection by the reflective portion extends the path of the supplementary light and adjusts the angle at which it illuminates the human eye, resulting in more uniform illumination, improved image quality, increased light efficiency, and reduced overall power consumption of the smart glasses.
