Description

Technical Field

[0001] This invention relates to the field of smart wearable device technology, specifically to an AR glasses with adaptive wearing adjustment and anti-dizziness display functions. Background Technology

[0002] Currently available augmented reality (AR) glasses generally suffer from the following two prominent problems during prolonged wear:

[0003] I. Wearing discomfort and insufficient stability

[0004] Most existing AR glasses use fixed or manually adjustable frame structures, which cannot dynamically adjust the clamping force according to the user's head shape, skin condition (such as slippage due to sweat), or wearing habits. During exercise, sweating, or prolonged use, the glasses are prone to loosening, slipping, or even falling off, which affects the stability of the displayed image and exacerbates visual fatigue and dizziness.

[0005] Second, the displayed image is out of sync with the user's attention, which can easily cause dizziness.

[0006] Current AR glasses typically employ a full-field, equal-resolution display strategy for rendering virtual images, failing to adequately consider the user's real-time gaze point, eye movements, and head posture changes. When users rapidly turn their heads or shift their gaze, the visual delay or misalignment between the virtual image and the real scene significantly enhances the conflict between the vestibular and visual systems, leading to discomfort symptoms such as dizziness and nausea.

[0007] To address the above issues, some existing products have attempted to adopt the following technical solutions:

[0008] Regarding fit and adjustment: Some AR glasses incorporate flexible materials (such as silicone pads) or manual adjustment mechanisms (such as extendable temples) in the temples or nose pads to improve fit. However, these solutions are still passively adaptive and cannot actively adjust the clamping force based on real-time wearing conditions (such as decreased friction due to humidity changes), resulting in limited adjustment accuracy and response speed.

[0009] Regarding anti-vertigo measures: Some products alleviate dizziness by increasing display refresh rate or reducing image latency, but they do not incorporate a mechanism for fusion and prediction of user gaze point and head movement, nor do they perform dynamic differentiated rendering of the display area. Therefore, visual conflict issues remain significant in fast-moving or complex visual environments.

[0010] In summary, existing AR glasses still have significant shortcomings in terms of adaptive adjustment and visual comfort optimization. There is an urgent need for an AR glasses structure that can integrate skin condition perception, gaze point recognition, and head movement prediction to achieve dynamic and personalized wearing and display control. Summary of the Invention

[0011] To address the above problems, the present invention provides AR glasses with adaptive wearing adjustment and anti-dizziness display functions.

[0012] To achieve the above objectives, the present invention provides the following technical solution: an AR glasses with adaptive wearing adjustment and anti-dizziness display functions, comprising a frame body, an optical display module, a posture sensing module, and a control unit. The frame body includes a front frame, temples disposed at both ends of the front frame, and two temples rotatably mounted on the two temples. It also includes: a humidity sensing layer embedded in the inner surface of the two temples and the nose pad contact surface of the front frame; a micro-drive unit embedded inside the two temples near the rotatable connection position; an optical display module installed in the front frame; a posture sensing module fixed inside the front frame or temples; and a control unit installed inside the temples. The humidity sensing layer is composed of a flexible substrate and multiple humidity sensing units embedded within the flexible substrate, used to collect spatial distribution data of humidity in the skin contact area. The micro-drive unit adjusts the rotation angle between the temples and temples. The posture sensing module collects the user's head movement data. The control unit is electrically connected to the humidity sensing layer, the micro-drive unit, the optical display module, and the posture sensing module.

[0013] Preferably, the miniature drive unit includes a drive element and a positioning component for fixing the position between the temple and the foot. The drive element includes a rotating column fixed to the end of the temple, a rotating rod rotatably passing through a rotating slot at the end of the rotating column, a driven gear fixedly sleeved on the body of the rotating rod, a drive gear disposed inside the temple and driven by a motor and meshing with the driven gear, and two rotating rings mounted on the end of the foot and symmetrically arranged about the rotating rod. When the foot is sleeved on both ends of the rotating rod by the two rotating rings, the two rotating rings are mounted on both ends of the rotating rod by mounting bolts.

[0014] Preferably, the positioning component includes a positioning rod that is movably inserted into the rotating slot and perpendicular to the length direction of the rotating column, a limiting rod that is movably inserted into the telescopic slot at one end of the positioning rod, a limiting spring that is inserted into the telescopic slot and connected at both ends to the bottom wall of the telescopic slot and the end of the limiting rod, and two electromagnets disposed on the bottom wall of the telescopic slot and the end of the limiting rod. When the limiting spring is in the normal extended state, the end of the limiting rod abuts against the side of the rotating rod.

[0015] Preferably, the control unit is configured as follows:

[0016] (a) Receive humidity spatial distribution data, calculate humidity gradient change rate, and determine the wearing loosening trend when the humidity gradient change rate exceeds the first threshold. Drive the element to adjust the opening angle between the temple and the temple so that the clamping force is restored to the set range.

[0017] (b) Receive eye movement data and head movement data, and use a filtering fusion method to generate the predicted position of the gaze point at the Nth frame in the future, where the value of N is determined by the degree of dispersion of the humidity spatial distribution data;

[0018] (c) Generate a dynamic field mask based on the predicted position of the gaze point, display a virtual image with a first rendering parameter within a first angular range around the predicted position of the gaze point, and display a virtual image with a second rendering parameter outside the first angular range. The clarity of the first rendering parameter is higher than that of the second rendering parameter. The size of the first angular range is positively correlated with the dispersion of the humidity spatial distribution data.

[0019] Preferably, the optical display module includes a waveguide lens, a microdisplay, and an eye-tracking sensor, which is used to collect the user's eye movement data.

[0020] Preferably, the inner surface of the optical waveguide lens is provided with an anti-reflection coating, which is composed of alternating stacked titanium dioxide layers and silicon dioxide layers, and at least covers the light coupling area of ​​the optical waveguide lens.

[0021] Preferably, the miniature drive unit also includes an angle sensor installed at the rotating connection position of the temple and the foot of the mirror. The angle sensor is electrically connected to the control unit and is used to detect the opening angle of the temple and the foot of the mirror in real time. The control unit uses the output value of the angle sensor as feedback to perform closed-loop control of the drive element.

[0022] Preferably, the control unit further includes a wireless communication module for establishing a data connection with an external computing device, sending the features of head movement data and humidity spatial distribution data to the external computing device, and receiving the predicted gaze point position returned by the external computing device.

[0023] The beneficial effects of this invention are:

[0024] 1. By arranging a humidity sensing layer on the inner side of the temples and the nose pads, the humidity spatial distribution data of the skin contact area is collected in real time. The control unit judges the trend of loosening of the glasses and drives the micro drive unit to adjust the opening angle between the temples and the temples, so as to achieve adaptive clamping force adjustment that becomes more stable the longer you wear them. This effectively prevents slippage caused by sweating or head movement and significantly improves the comfort and stability of wearing them for a long time.

[0025] 2. Combining the eye-tracking unit and the posture sensing module, the control unit uses a filtering fusion method to predict the user's gaze point position at the Nth frame in the future, and generates a dynamic visual field mask accordingly. Virtual images are rendered in high definition only within a first angular range around the predicted gaze point position, while the outer regions are rendered in low resolution or with blurred detail. This differentiated rendering strategy significantly reduces the conflict between the visual and vestibular systems, effectively suppressing dizziness caused by visual misalignment or delay.

[0026] 3. The control unit dynamically adjusts the frame number N for gaze point prediction and the first angle range of the high-definition display area based on the dispersion of humidity spatial distribution data. When humidity distribution is uneven or changes drastically, the system automatically expands the effective field of view and shortens the prediction time window, improving the tracking and stability of the displayed content and further enhancing the anti-dizziness effect.

[0032] To make the technical means, creative features, achieved objectives, and effects of this invention readily understandable, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0033] Example 1: Reference Figures 1-3 The AR glasses shown include an adaptive wearing adjustment and anti-dizziness display function, comprising a frame body, an optical display module, a posture sensing module 5 and a control unit, with a dynamic image rendering unit 3 set on the frame.

[0034] The main body of the eyeglass frame includes a front frame, temples 8 located at both ends of the front frame, and two fovea 9 rotatably mounted on the two temples 8. A humidity sensing layer is embedded in the inner surface of the two temples 8 and the nose pad contact surface of the front frame. This humidity sensing layer consists of a flexible substrate and multiple capacitive humidity sensing units (using humidity sensors 1) embedded within the flexible substrate, used to collect spatial distribution data of humidity in the skin contact area. The capacitive humidity sensing units are arranged in an array, capable of detecting local humidity gradient changes.

[0035] A micro-drive unit is embedded inside each temple 8, near the position where it rotates with the temple 9. The micro-drive unit is used to adjust the rotation angle between the temple 8 and the temple 9. The attitude sensing module 5 is fixed inside the front frame or temple 8, preferably a six-axis inertial measurement unit (IMU), for collecting the user's head motion data (including three-axis angular velocity and three-axis acceleration). The control unit is installed inside the temple 8 and is electrically connected to the humidity sensing layer, the micro-drive unit, the optical display module, and the attitude sensing module 5. An audio unit 6 is embedded on the side of the temple 9.

[0036] like Figures 1-3 As shown, the micro-drive unit includes a drive element and a positioning component. Specifically, a rotating column 10 is fixed to the end of the temple 8, and a rotating slot 13 is formed at the end of the rotating column 10. A rotating rod 14 is rotatably inserted into the rotating slot 13, and a driven gear 15 is fixedly sleeved on the body of the rotating rod 14. A micro motor is installed inside the temple 8, and a drive gear 16 that meshes with the driven gear 15 is fixed on the output shaft of the motor. Two symmetrically arranged rotating rings 11 are provided at the end of the temple 9. The two rotating rings 11 are respectively sleeved on both ends of the rotating rod 14 and fixed to the rotating rod 14 by mounting bolts 12. When the drive gear 16 drives the driven gear 15 to rotate, the rotating rod 14 rotates relative to the rotating column 10, thereby causing the temple 9 to open or close relative to the temple 8, realizing dynamic adjustment of the temple clamping force.

[0037] To further improve the stability and safety of the adjustment, the positioning components include a positioning rod 17, a limiting rod 18, a limiting spring, and two electromagnets. The positioning rod 17 is movably inserted into the rotating slot 13 and is perpendicular to the length direction of the rotating column 10. A telescopic groove is formed at the end of the positioning rod 17, and one end of the limiting rod 18 is movably inserted into this telescopic groove. The limiting spring is inserted into the telescopic groove, with its two ends connected to the bottom wall of the telescopic groove and the end of the limiting rod 18, respectively. The two electromagnets are respectively located on the bottom wall of the telescopic groove and the end of the limiting rod 18. In the initial state, the limiting spring is in its normal extended state, and the end of the limiting rod 18 abuts against the side of the rotating rod 14, forming a friction limit to prevent the rotating rod 14 from rotating accidentally. When the angle needs to be actively adjusted, the control unit energizes the two electromagnets, causing them to attract each other and overcome the force of the limit spring to retract the limit rod 18 into the telescopic groove, thus releasing the limit on the rotating rod 14. After the adjustment is completed, the power supply to the electromagnets is disconnected, and the limit rod 18 pops out again and abuts against the side of the rotating rod 14.

[0038] The optical display module includes a waveguide lens 4, a microdisplay, and an eye-tracking sensor. The eye-tracking sensor is preferably an infrared interferometer with a sampling frequency of at least 240Hz and an accuracy of 0.1°, used to collect the user's eye movement data (including gaze direction, saccade speed, pupil position, etc.). An anti-reflective coating is provided on the inner surface of the waveguide lens 4. This anti-reflective coating consists of alternating layers of titanium dioxide and silicon dioxide, covering at least the light coupling area of ​​the waveguide lens 4 to improve light coupling efficiency and reduce the power consumption of the microdisplay.

[0039] The control unit is configured to perform the following steps:

[0040] Step (a) Adaptive Wearing Adjustment: The control unit receives humidity spatial distribution data from the humidity sensing layer and calculates the humidity gradient change rate (i.e., the maximum difference in humidity change per unit area). When the humidity gradient change rate exceeds a preset first threshold (e.g., 0.15% RH / mm), it is determined that the wearer is becoming loose (usually due to decreased friction caused by sweating behind the ears or nose pads). At this time, the control unit activates the drive motor in the micro-drive unit, and the drive gear 16 drives the driven gear 15 to rotate, reducing the opening angle of the temple 9 relative to the temple 8 by 0.5° to 3°, thereby increasing the clamping force of the temple on the user's head until the humidity gradient change rate returns to the normal range. This closed-loop adjustment process can be performed in real time, achieving adaptive wearing that becomes more stable the more you wear it.

[0041] Step (b) Gaze Prediction: The control unit receives eye movement data from the eye-tracking sensor and head movement data from the posture sensing module 5 in real time. An extended Kalman filter (EKF) or complementary filter fusion method is used to predict the gaze position at the Nth frame (e.g., the 3rd frame, approximately 20ms later). The value of N is determined by the dispersion of the humidity spatial distribution data. The dispersion can be represented by the variance or range of the humidity data. When the humidity distribution is extremely uneven (e.g., the variance is higher than the second threshold), it indicates that the user may be in a state of vigorous movement or frequent head turning. In this case, N is taken as a smaller value (e.g., 1-2 frames) to improve the prediction response speed; when the humidity distribution is uniform, N is taken as a larger value (e.g., 4-5 frames) to reduce the computational load.

[0042] Step (c) Dynamic Field of View Mask: Based on the predicted gaze point location, the control unit generates a dynamic field of view mask. Within a first angular range (e.g., ±5°) around the predicted gaze point location, a virtual image is displayed with first rendering parameters, which are full resolution (1080p or higher), high frame rate (≥60Hz), high brightness, and high contrast. Outside the first angular range, a virtual image is displayed with second rendering parameters, which are reduced resolution (e.g., reduced to 720p), reduced frame rate (e.g., 30Hz or lower), and edge blurring. The size of the first angular range is positively correlated with the dispersion of the humidity spatial distribution data: when the humidity dispersion is high (user activity is intense), the first angular range is expanded to, for example, ±8° to ensure that key information within the user's field of view is not lost; when the humidity dispersion is low (user is relatively stationary), the first angular range can be reduced to ±3° to further reduce peripheral visual interference.

[0043] By employing the aforementioned differentiated rendering strategies, the visual and vestibular system conflicts caused by full-view high-definition rendering are significantly reduced, effectively suppressing dizziness.

[0044] Example 2: Regarding how to optimize the closed-loop control accuracy of the micro drive unit 2 in Example 1 above, this example provides the following solution.

[0045] This embodiment further optimizes the closed-loop control accuracy of the micro-drive unit 2 based on embodiment 1. The micro-drive unit 2 also includes an angle sensor installed at the rotational connection point between the temple 8 and the temple 9. The angle sensor is electrically connected to the control unit and is used to detect the opening angle between the temple 8 and the temple 9 in real time. The control unit uses the output value of the angle sensor as feedback to perform PID closed-loop control on the drive element (drive motor), ensuring that the adjusted angle error is controlled within ±0.1°, avoiding over-clamping or under-adjustment.

[0046] Example 3

[0047] This embodiment adds wireless communication functionality to Embodiment 1 or 2. The control unit also includes a Bluetooth or Wi-Fi wireless communication module. This module is used to establish a data connection with an external computing device (e.g., a smartphone, tablet, or edge computing gateway). The control unit sends the characteristics of head motion data (e.g., angular velocity sequence, acceleration sequence) and the characteristics of humidity spatial distribution data (e.g., humidity mean, variance, gradient direction) to the external computing device. The external computing device uses its NPU or GPU to run a pre-trained neural network model, performs complex calculations such as gaze point prediction, and returns the predicted gaze point position to the control unit of the AR glasses. This method reduces the computing power and power consumption of the AR glasses themselves, making it suitable for wearable devices with sensitive battery life.

[0048] It is understandable that the micro-drive unit is not limited to gear transmission; it can also employ micro-lead screws, shape memory alloys (SMA), or piezoelectric ceramics. The humidity sensing layer can also be replaced with a resistive humidity sensor array or a capacitive-resistive hybrid array. Parameters such as the first threshold, second threshold, N value, and first angle range can all be adjusted online according to the user's wearing habits through a self-learning algorithm.

[0049] Example 4

[0050] This embodiment further improves the rear end connection structure of the frame body based on embodiments 1, 2, or 3 described above. Please refer to... Figure 1 The two temples 9 of the frame body are each provided with an elastic headband connection structure 7 at their rear ends (i.e., the ends away from the temples 8). The elastic headband connection structure 7 includes an elastic headband, an adjustable sliding buckle, and a fixing ring or hook;

[0051] Elastic headband: Made of wide, flat elastic braided strips or silicone-coated elastic bands, it is used to provide auxiliary fixation around the back of the user's head.

[0052] Adjustable sliding buckle: Located inside or outside the rear end of each temple 9, it connects to one end of the elastic headband. The adjustable sliding buckle includes a ratchet or slider adjustment mechanism with at least three positions, allowing users to manually adjust the effective length of the elastic headband according to their head circumference, thus achieving multi-position head circumference adaptation.

[0053] Fixing loop or hook: The other end of the elastic headband can be detachably connected to the back of the other temple via a fixing loop or hook, making it easy for users to put on and take off the glasses.

[0054] Each of the two temples 9 has a receiving groove at its rear end, into which an adjustable sliding buckle is installed. One end of the elastic headband passes through the through hole of the adjustable sliding buckle and is fixed to the ratchet rack or slider inside the buckle. The other end goes around the back of the user's head and is connected to the opposite temple via a hook. When the user presses or flips the release button of the adjustable sliding buckle, the elastic headband can be pulled out in the direction of increasing head circumference or pulled back in the direction of decreasing head circumference. After releasing the button, the ratchet or friction plate automatically locks in place, maintaining the current length.

[0055] When the control unit performs adaptive adjustment, the micro-drive unit primarily adjusts the rotation angle between the temples 8 and 9, thereby changing the clamping force of the temples on the area in front of the ear. The elastic headband connection structure, independent of this dynamic adjustment, provides passive auxiliary fixation force to the back of the head, forming a dual fixation system of "front clamp, back pull." This structure is particularly suitable for sports activities or situations involving large head rotations. Even if the clamping force of the temples temporarily decreases due to sweating, the elastic headband still prevents the glasses from slipping forward, significantly improving wearing stability.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
