Description

Technical Field

[0001] This application relates to the field of head-mounted smart devices, and more particularly to a smart device. Background Technology

[0002] The application of head-mounted smart devices is becoming increasingly widespread. For example, AR (Augmented Reality) glasses can provide users with many convenient functions. When users interact with AR glasses, smart devices can detect the user's eye movement state, so that users can interact with head-mounted smart devices naturally and efficiently using eye movements. Users can select or control virtual objects simply by looking at them.

[0003] Specifically, smart devices can output light signals to the user's eyes through optical components and generate detection signals representing eye movement status based on the light signals reflected by the eyes. However, due to the large size and small installation space of existing optical components, not only is the overall size of the head-mounted smart device large, but the optical components cannot be well fixed in the smart device. The poor installation stability of the optical components causes the light signals output by the optical components to have large angular deviations during shaking, affecting the accuracy of eye movement detection and resulting in a poor wearing experience for the user.

[0030] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] Currently, eye-tracking technology has broad application prospects in smart devices, particularly in eye health monitoring and AR spatial eye-tracking interaction, demonstrating significant potential. By monitoring the user's gaze direction and gaze target, eye tracking not only enhances the user experience but also provides crucial eye health data support. In eye health monitoring, eye tracking can monitor eye movement patterns, blink frequency, and eye movement trajectories in real time, helping users identify eye health problems such as dry eye and eye strain, providing daily eye health monitoring. In AR spatial eye-tracking interaction, users can select or manipulate virtual objects simply by looking at them, achieving a more natural and efficient interactive experience. This approach improves the convenience and user engagement of AR applications, showing broad application prospects in fields such as gaming, education, healthcare, and industrial design. In conclusion, eye-tracking technology brings revolutionary functional improvements and eye health management support to smart devices (especially smart glasses), driving the development and popularization of AR technology.

[0032] In related technologies, eye-tracking technology primarily relies on low-power infrared sensing to determine the eye's gaze position. To achieve accuracy in eye-tracking recognition, both the transmitter (Tx end) and receiver (Rx end) need to be controlled within a reasonable field of view (FOV). If the transmitter's FOV is too large, the light will be excessively diffused, resulting in high illumination power consumption. If the receiver's FOV is too large, the receiver's accuracy will be compromised, reducing sensing sensitivity. If the FOVs of the Tx and Rx ends are too small, the illumination and sensing range will be too limited, failing to adapt to different eyewear positions and the diversity of wearers. Therefore, controlling the FOV angle of the Tx and Rx ends is a crucial parameter in eye-tracking. To achieve stable FOV angle control, the optical components of both the transmitter (Tx end) and receiver (Rx end) on the smart device need to be stably and precisely installed and fixed.

[0033] like Figure 1 As shown, related technologies design and control the divergence angle of the Tx or Rx end by encapsulating a convex lens within the cavity of the wearable bracket. However, on the one hand, this encapsulation method results in a large overall thickness of the smart device due to the large thickness of the convex lens itself, with the height between the circuit board and the product casing reaching 2-4mm, making the smart device bulky. On the other hand, since the convex lens is directly encapsulated on the light output module and light receiving module, the installation accuracy and stability depend on the control of the encapsulation process. The convex lens cannot be properly fixed inside the smart device, causing a large angular deviation in the light signal of the smart device during use, affecting the accuracy of eye movement detection, and thus resulting in a poor user experience.

[0034] To address the aforementioned issues, this application provides a smart device designed to improve the stability of optical component installation, enhance the accuracy of eye movement detection, and thereby improve the user's wearable experience.

[0035] In this application embodiment, the smart device can be a head-mounted smart device such as smart glasses or a smart helmet. Taking smart glasses as an example, smart glasses refer to AR (Augmented Reality) glasses, XR (Extender Reality) glasses, and MR (Mixed Reality) glasses. It can also be other glasses that include waveguide lenses and optical lenses. All of the above glasses can use the smart device provided in this application embodiment, and no specific limitation is made here.

[0036] The following introduction uses smart glasses as an example of a smart device.

[0037] like Figures 2-6 As shown, the smart device 100 includes at least a wearable bracket 10, a substrate 20, a light output module 30, a light receiving module 40, and an optical component 50. The wearable bracket 10 has a cavity 11. In some embodiments, the wearable bracket 10 is formed from the housing of the smart device 100, and the wearable bracket 10 forms the cavity 11. The substrate 20 is housed within the cavity 11 and fixedly disposed therein, for housing the light output module 30 and the light receiving module 40. The substrate 20 can be a single, integral plate for housing the light output module 30 and the light receiving module 40, or it can be separate plates for housing the light output module 30 and the light receiving module 40 respectively. The light output module 30 is disposed on the substrate 20 and housed in the cavity 11. The light output module 30 is configured to output emitted light signals to a target area of ​​the wearer's eyes. The light receiving module 40 is disposed on the substrate 20 and housed in the cavity 11. The light receiving module 40 is configured to receive reflected light signals formed by the reflected emitted light signals from the eyes. The target area refers to the region corresponding to the wearer's eyes, such as the area of ​​the wearer's eyeball's movement. Since the eyeball can generally move in horizontal and vertical directions, its movement area mainly refers to the area formed by the eyeball rotating to the maximum extent in all directions through the contraction and coordination of the extraocular muscles. The target area is generally the area of ​​the eyeball exposed outside the eyelids when the wearer's eyes are open.

[0038] Preferably, this application utilizes infrared sensing intensity to detect the direction of the gaze point, the distance to the gaze point, and eye activities such as blinking. To achieve good detection results, sensitivity and power consumption control are crucial. The core principle of eye tracking is to accurately locate the gaze point by utilizing the differences in infrared light reflection from different eye structures when the eye is illuminated. The sclera, iris, and pupil have different reflective abilities to infrared light. The sclera has strong reflective ability; the iris generally reflects less infrared light than the sclera; the pupil reflects less infrared light than both the iris and sclera, resulting in a dark area at the center of the pupil under infrared light illumination. Preferably, the target area includes at least the sclera of the wearer's eye.

[0039] In some embodiments, the mounting bracket 60 is connected to the substrate 20; in some embodiments, the mounting bracket 60 is connected to the wearable bracket 10; in some embodiments, the mounting bracket 60 may be connected to both the substrate 20 and the wearable bracket 10.

[0040] The optical component 50 is housed in the cavity 11 and spaced apart from the wearable bracket 10. In some embodiments, the optical component 50 is disposed on the light output path of the light output module 30 via a mounting bracket 60 and is configured to adapt the coverage area of ​​the emitted light signal to the target area; in some embodiments, the optical component 50 is disposed on the light receiving path of the light receiving module 40 via a mounting bracket 60 and is configured to gather the reflected light signal.

[0041] Understandably, compared to the method in related technologies of encapsulating convex lenses in the cavity of wearable brackets using thick encapsulation structures such as colloids, this application fixes the optical component 50 in the cavity 11 using the mounting bracket 60, making the installation of the optical component 50 convenient and stable. Even during shaking, the output light signal will not have a large angular deviation. This not only improves the stability of the optical component 50, but also, because the mounting bracket 60 is thin and stable, it can effectively reduce the design thickness of the cavity 11, thereby reducing the overall thickness of the smart device 100. This makes the smart device 100 lighter and more portable, improves the accuracy of eye movement detection, and thus improves the user's wearing experience.

[0042] Specifically, the light output module 30 needs to emit infrared light of a certain energy to illuminate the human eye, and the light receiving module 40 then receives the infrared light reflected from the human eye. The smart device 100 processes the reflected light intensity signal to determine the information of the human eye's gaze point. To achieve more accurate and sensitive eye-tracking sensing, the field of view of the light receiving module 40 needs to be precisely controlled. A field of view that is too large will cause the light intensity signal to be dispersed, making it impossible to obtain more sensitive sensing data. A field of view that is too small will result in poor fit of the user's glasses, and the eyes may not be illuminated at all under different wearing positions, resulting in no eye-tracking data being generated. Furthermore, to achieve the goal of all-weather eye-tracking detection, the light emitted by the light output module 30 needs to be better utilized. An excessively large field of view will cause the illumination of many useless surrounding lighting areas, resulting in wasted power consumption; an excessively small field of view will result in poor fit of the user's glasses, and may also result in the inability to collect user eye-tracking data under different wearing positions.

[0043] Therefore, given the importance of the field of view of the light output module 30 and the light receiving module 40, it is necessary to configure the optical component 50 to control the field of view, so as to control the field of view of the light output module 30 and the light receiving module 40 within the optimal range, so that the light signal can be fully utilized, without wasting power consumption, and meeting the requirements of the detection range.

[0044] In some embodiments, the optical component 50 is located on the light output path of the light output module 30 and is configured to adapt the coverage area of ​​the emitted light signal to the target area; in some embodiments, the optical component 50 is located on the light receiving path of the light receiving module 40 and is configured to gather the reflected light signal.

[0045] Specifically, the coverage area of ​​the emitted optical signal is determined by the field of view of the emitted optical signal. It can be understood that the range of the field of view corresponding to the emitted optical signal is the coverage area of ​​the emitted optical signal. For the coverage area of ​​the emitted optical signal to be compatible with the target area, the range of the field of view corresponding to the emitted optical signal must be at least greater than or equal to the range of the target area, and the range of the field of view must be controlled to not be significantly larger than the target area, thus avoiding wasted power consumption.

[0046] For example, such as Figure 4 As shown, the optical component 50 is mounted on the light output path of the light output module 30 via the mounting bracket 60. At this time, the optical component 50 is configured to adapt the coverage area of ​​the emitted light signal to the target area.

[0047] For example, such as Figure 5 As shown, the optical component 50 is mounted on the light receiving path of the light receiving module 40 via the mounting bracket 60, and the optical component 50 is configured to gather and reflect light signals.

[0048] For example, such as Figure 6As shown, the first optical component 51 is mounted on the light output path of the light output module 30 via the first mounting bracket 61, and the second optical component 52 is mounted on the light receiving path of the light receiving module 40 via the second mounting bracket 62. At this time, the first optical component 51 on the light output path is configured to adapt the coverage area of ​​the emitted light signal to the target area, and the second optical component 52 on the light receiving path is configured to gather the reflected light signal.

[0049] It should be noted that the optical component 50 can be mounted on either the light output path or the light receiving path via the mounting bracket 60. For example, if the optical component 50 is mounted on the light output path via the mounting bracket 60, the optical component 50 may not be mounted on the light receiving path, or any type of optical component 50 may be mounted on it. Furthermore, the optical components 50 on the light output path and the light receiving path can be any combination of the following embodiments.

[0050] The optical component 50 of this application is set in the light output path or light receiving path by the mounting bracket 60. That is, the mounting bracket 60 fixes the optical component 50 in the cavity 11. This makes the light signal output by the optical component 50 not have a large angular deviation even during shaking. This not only improves the stability of the optical component 50, but also enables precise control of the field of view, ensuring that the light signal can be fully utilized and that no power consumption is wasted.

[0051] In some embodiments, the optical component 50 includes a first optical component 51 located in the light output path and configured to adapt the coverage area of ​​the emitted light signal to the target area; in some embodiments, the optical component 50 includes a second optical component 52 located in the light receiving path and configured to gather the reflected light signal.

[0052] For example, the optical component 50 may include only the first optical component 51, which is disposed on the light output path via the mounting bracket 60; or it may include only the second optical component 52, which is disposed on the light receiving path via the mounting bracket 60; or it may include both the first optical component 51 and the second optical component 52, which are disposed on the light output path and the light receiving path respectively via the mounting bracket 60. No specific limitation is made here.

[0053] In some embodiments, the coverage area when the emitted light signal is emitted is larger than the target area, and the first optical component 51 is configured as a light-concentrating device; or, the coverage area when the emitted light signal is emitted is smaller than the target area, and the first optical component 51 is configured as a light-diffusing device.

[0054] The area covered by the emitted light signal is the field of view range corresponding to the emitted light signal.

[0055] For example, if the light output module 30 is a divergent light source, the coverage area of ​​the emitted light signal output by the divergent light source is generally larger than the target area. This indicates that the field of view is large and the emitted light signal is relatively divergent, resulting in illuminating many useless surrounding lighting areas, thus wasting power. Therefore, the first optical component 51 is configured as a focusing device to concentrate the emitted light signal.

[0056] For example, if the light output module 30 is a concentrated light source, the coverage area of ​​the emitted light signal output by the concentrated light source is generally smaller than the target area. This indicates that the field of view is small and the emitted light signal is more concentrated, which may lead to poor user fit. Under different wearing positions, it is easy to fail to collect user eye movement data. Therefore, the first optical component 51 is configured as a light diffusion device to diffuse the emitted light signal.

[0057] It should be noted that concentrated light sources include light sources that emit light signals that converge toward the center, as well as parallel light sources that emit light signals with a smaller illumination range and concentrated energy; no specific limitation is made here.

[0058] In some embodiments, the mounting bracket 60 includes a first mounting bracket 61, through which the first optical component 51 is disposed on the light output path; in some embodiments, the mounting bracket 60 includes a second mounting bracket 62, through which the second optical component 52 is disposed on the light receiving path.

[0059] For example, the first mounting bracket 61 is connected to the substrate 20 or the wearable bracket 10, and the first optical component 51 is disposed on the light output path through the first mounting bracket 61.

[0060] For example, the second mounting bracket 62 is connected to the substrate 20 or the wearable bracket 10, and the second optical component 52 is disposed on the light receiving path via the second mounting bracket 62.

[0061] Preferably, both the first mounting bracket 61 and the second mounting bracket 62 are connected to the substrate 20 or the wearable bracket 10, and the first optical component 51 is disposed on the light output path via the first mounting bracket 61, while the second optical component 52 is disposed on the light receiving path via the second mounting bracket 62. This allows the optical component 50 to be fixedly mounted within the cavity 11, ensuring that the light signal output by the optical component 50 does not exhibit significant angular deviation even during shaking, thereby improving the stability of the optical component 50 and the accuracy of eye movement detection.

[0062] For example, the first mounting bracket 61 and the second mounting bracket 62, as positioning components, can be connected to the substrate 20 or the wearable bracket 10 via contacts, annular positioning portions, strip-shaped positioning portions, wavy positioning portions, or positioning portions of any regular or irregular shape. For example, the first mounting bracket 61 and the second mounting bracket 62 can also be provided with multiple alignment contacts, which can be symmetrically arranged around the light output module 30 or the light receiving module 40. For example, the multiple alignment contacts can be arranged in an annular shape around the light output module 30 or the light receiving module 40, or in a rectangular shape around the light output module 30 or the light receiving module 40. This allows the first mounting bracket 61 and the second mounting bracket 62 to not only support the first optical component 51 and the second optical component 52, but also to seal the light output module 30 and the light receiving module 40, thereby protecting the light output module 30 and the light receiving module 40.

[0063] In some embodiments, the optical component 50 is a planar optical device, which includes a planar focusing device or a planar light diffusing device located on the light output path; in some embodiments, the planar optical device includes a planar focusing device located on the light receiving path. Configuring the optical component 50 as a planar optical device effectively reduces the design thickness of the cavity 11, thereby reducing the overall thickness of the smart device 100, making the smart device 100 lighter and more portable. Furthermore, the smart device 100 can utilize the small size of the optical component 50 to place the light output module 30, the light receiving module 40, and the optical component 50 in the head regions at both ends of the smart device 100, without occupying the volume of the main frame. This greatly enhances the product's aesthetics while also providing eye-tracking functionality in a suitable position, improving the user's wearing experience.

[0064] Unlike traditional curved optical elements (such as ordinary thick lenses, prisms, and mirrors), the planar optical device of this application refers to an optical device with a micrometer-scale lens or micro / nano structure that achieves the same optical function such as light focusing or light diffusion. Micro / nano structures refer to structures with a thickness no greater than the micrometer or nanometer scale. Planar optical devices are optical devices with a thickness smaller than traditional curved optical elements (such as ordinary lenses, prisms, and mirrors), and can be considered as a plane (or approximately a plane) overall. In some embodiments, the planar optical device can precisely control the phase, amplitude, polarization, or propagation direction of light by designing and fabricating subwavelength-scale micro / nano structures on a planar substrate.

[0065] For example, if the light output module 30 is a divergent light source, the first optical component 51 can be a planar focusing device, which may include a superlens or a microlens array; if the light output module 30 is a focused light source, the first optical component 51 can be a planar light diffusing device, which may include a superlens, a microlens array, or a diffuser. For example, the second optical component 52 is generally a planar focusing device, which may include a superlens or a microlens array.

[0066] It should be noted that a planar focusing device refers to an optical device whose optical structure thickness is smaller than that of a traditional curved optical element when achieving the same focusing effect, and the whole device can be regarded as a plane (or approximately a plane). A planar light diffusing device refers to an optical device whose optical structure thickness is smaller than that of a traditional curved optical element when achieving the same light diffusing effect, and the whole device can be regarded as a plane (or approximately a plane). Depending on different internal structures, different arrays of superlenses or microlenses can achieve focusing or light diffusing. The planar focusing device defined in this application includes arrays of superlenses or microlenses, or optical devices with similar structures that achieve similar focusing functions. A superlens refers to a planar optical device based on metasurface technology, which achieves precise control of the incident light wavefront by designing an array of artificial nanostructures at the subwavelength scale, thereby replacing the focusing or imaging function of traditional curved lenses. A microlens array (MLA) is an optical device in which miniature curved lens units are densely arranged on a planar substrate. Each unit independently controls the light through the principle of geometric refraction, achieving functions such as multifocal imaging, beam homogenization, or light field modulation. A diffuser is an optical thin film or flat panel device that scatters incident light through physical or optical microstructures, thereby converting a directional beam into uniformly diffused light. The diffuser in this application can include diffusers of different thicknesses; generally, thinner diffusers are diffuser films. Exemplary diffusers can include diffractive optical diffusers, refractive optical diffusers, and microstructured optical diffusers, etc.

[0067] For example, the light output module 30 can use a vertical cavity surface-emitting laser (VCSEL), which can increase the photoelectric conversion efficiency (PCE) to about twice that of LED lighting, thereby reducing the overall power consumption of the smart device 100 and enabling all-weather standby for infrared detection.

[0068] In some embodiments, the optical component 50 located on the light output path is configured to make the emitted light signal output uniform.

[0069] For example, the first optical component 51 is also configured to emit a uniform light signal. This allows the emitted light signal output by the light output module 30 to be uniformly emitted toward the target area of ​​the wearer's eye, thereby improving the sensitivity and accuracy of eye movement detection.

[0070] In some embodiments, the wearable bracket 10 includes a first light-transmitting portion located on the light output path and a second light-transmitting portion located on the light receiving path. The first light-transmitting portion is configured to transmit emitted light signals, and the second light-transmitting portion is configured to transmit reflected light signals.

[0071] For example, the first light-transmitting part located on the light output path is used to transmit the emitted light signal so that the emitted light signal can be transmitted to the target area, and the second light-transmitting part located on the light receiving path is used to transmit the reflected light signal so that the reflected light signal can be received by the light receiving module 40.

[0072] like Figure 7 As shown, in some embodiments, light receiving modules 40 corresponding to the left and right eyes are respectively provided on both sides of the smart device 100. In some embodiments, the light receiving module 40 on one side includes at least a first light receiving module 41 and a second light receiving module 42, which are disposed on opposite sides of the light output module 30 in the height direction of the smart device 100; wherein, the first light receiving module 41 is configured to receive reflected light signals within a first light receiving range, and the second light receiving module 42 is configured to receive reflected light signals within a second light receiving range, and the first light receiving range and the second light receiving range do not overlap at least partially.

[0073] For example, by placing the first light receiving module 41 and the second light receiving module 42 on opposite sides of the light output module 30 in the height direction of the smart device 100, the first light receiving module 41, the second light receiving module 42, and the light output module 30 are arranged vertically. Since most users' left-right orientation when wearing smart glasses is relatively symmetrical, in the vertical direction, because the positions of each user's ears and nose may be different, the height of the smart glasses worn by each user will vary. The vertical arrangement provided in this embodiment allows the first light receiving module 41 and the second light receiving module 42 to cover as many positions as possible of different users wearing smart glasses in the vertical direction, thereby further improving the range and accuracy of eye-tracking recognition.

[0074] like Figure 2 and Figure 3 As shown, in some embodiments, the wearable bracket 10 includes a frame member 12 and a temple member 13. Temple connecting portions are provided on opposite sides of the frame member 12, and the temple member 13 is connected to the frame member 12 through the temple connecting portions; wherein, the temple connecting portion forms a cavity 11.

[0075] For example, the frame member 12 can be used to mount the lens module. Temple connecting portions are provided on opposite sides of the frame member 12, through which the temple member 13 can be mounted on the frame member 12, thereby achieving the connection between the temple member 13 and the frame member 12. The temple connecting portion forms a cavity 11, and the substrate 20, the light output module 30, and the light receiving module 40 are all housed within the cavity 11.

[0076] In some embodiments, the smart device 100 further includes a controller, which is configured to receive a detection signal generated by the light receiving module 40 based on the reflected light signal, and determine the eye movement state of the wearer's eyes based on the detection signal.

[0077] The detection signal can be an electrical signal generated from the reflected light signal.

[0078] For example, the smart device 100 also includes a controller that can control the light output module 30 to output emitted light signals to the target area of ​​the wearer's eyes, and then control the light receiving module 40 to receive detection signals generated based on the emitted light signals reflected back from the eyes, and accurately determine the wearer's eye movement state based on the detection signals, so that the smart device 100 can interact with the user through the collected eye movement state.

[0079] In some embodiments, the smart device 100 further includes a temperature sensing module connected to a controller. The temperature sensing module is used to sense the temperature of the smart device 100 and output a corresponding temperature signal. The controller is also configured to determine a first compensated eye movement state of the eye based on the detection signal and the temperature signal. In some embodiments, the smart device 100 further includes an ambient light sensing module connected to the controller. The ambient light sensing module is used to sense the ambient light of the smart device 100 and output a corresponding ambient light signal. The controller is also configured to determine a second compensated eye movement state of the eye based on the detection signal and the ambient light signal.

[0080] The temperature sensing module can be a sensor used to collect the temperature of the smart device 100, and the ambient light sensing module can be a sensor used to collect the ambient light intensity. The first compensated eye-tracking state can be the compensated eye-tracking state after eliminating the influence of temperature factors, and the second compensated eye-tracking state can be the compensated eye-tracking state after eliminating the influence of ambient light factors.

[0081] For example, the temperature sensing module can collect the temperature of the smart device 100 and output the corresponding temperature signal. The controller can determine the first compensated eye movement state of the eye based on the detection signal and the temperature signal. Thus, the ambient temperature of the smart device 100 can be sensed by using a temperature sensor (such as a thermistor), so as to compensate for the difference caused by temperature changes in the eye movement algorithm, thereby eliminating the influence of temperature factors and generating the corresponding first compensated eye movement state.

[0082] For example, the ambient light sensing module can collect the ambient light of the smart device 100 and output the corresponding ambient light signal. The controller can determine the second compensated eye movement state of the eye based on the detection signal and the ambient light signal. Thus, the ambient light sensor can be used to sense the spectrum of the ambient light where the smart device 100 is located, thereby compensating for the differences caused by changes in ambient light in the eye movement algorithm. This can eliminate the influence of infrared light in the environment where the ambient light is located and generate the corresponding second compensated eye movement state.
