In outdoor activities such as hiking, climbing, and cycling, the wearer can determine the direction of travel through the geomagnetic sensor on the AR glasses 100. In addition, the geomagnetic sensor 31 can also cooperate with the accelerometer, gyroscope and GPS. The geomagnetic sensor 31 can more accurately track the user's posture and motion trajectory.

Specifically, for the head turning action of the wearer, the rotation angle data around the vertical axis (generally the axis when the head is turned left and right) is focused on, and the data collected by the accelerometer and the gyroscope is converted into angle information easy to understand and process by using a data processing algorithm, for example, the original acceleration and angular velocity data is converted into the angle value of the head turning, a threshold value of the head turning angle is determined in advance, when the angle of the head turning of the wearer exceeds the threshold value, the system issues an instruction to control the display module to perform the screen-out operation, and when the head turning angle returns to the normal range, the screen-on operation can be triggered. The threshold value of the head turning angle can be adjusted according to actual test and user experience, for example, the screen-out is triggered when the head turning exceeds 45° or 60°.

[0052] Among them, the installation positions of the accelerometer, the gyroscope, the heart rate sensor, the positioning sensor, the barometer, the ultraviolet sensor, the ambient light sensor, the blood oxygen sensor, the body temperature sensor and the environmental temperature sensor can also be selected according to actual needs. For example, the accelerometer, the gyroscope and the ultraviolet sensor are all installed at the middle position of the frame 10. The positioning sensor is installed at the position close to the temple 20 of the frame 10, the heart rate sensor, the blood oxygen sensor and the barometer are installed at the temple 20, and the ambient light sensor, the body temperature sensor and the environmental temperature sensor are all installed on the frame 10. It can be understood that the sensors among the above sensors that do not produce significant electromagnetic interference to the geomagnetic sensor 31 can be installed at the middle position of the frame 10.
[0053] In the embodiment, as shown in FIG. 1, the AR glasses 100 include a frame 10, a left temple 20, a right temple 20', a display module 30, a data acquisition module 30', a data processing module 30'', a communication module 30''' and a power supply module 30''''. The frame 10 is provided with a left lens 10' and a right lens 10'', and the left temple 20 and the right temple 20' are respectively connected to the left lens 10' and the right lens 10''. Figures 1 to 3As shown, the power module 60 is installed on the temple 20, and the data processing module 40 is installed on the frame 10 close to the temple 20, so that the power module 60 and the data processing module 40 are respectively away from the geomagnetic sensor 31 on the bridge 12, so as to further reduce the electromagnetic interference on the geomagnetic sensor 31. The temple 20 and the frame 10 each have a receiving cavity, and the power module 60 and the data processing module 40 are respectively installed in the corresponding receiving cavities.
[0054] In the embodiment, as shown in Figures 1 to 3 The display module 50 includes a projection unit 51 and an optical unit 52. The projection unit 51 is used to project image light containing motion data information. The optical unit 52 is used to conduct the image light to the human eye, so that the wearer can see the motion data information. The image light of the motion data information includes motion parameters such as the wearer's step count, calories, distance, speed, and altitude, physiological health data such as heart rate, blood oxygen, and body temperature, and environmental information such as ultraviolet intensity and environmental temperature. The projection unit 51 and the optical unit 52 are installed on the lens holder 11. The projection unit 51 is close to the temple 20, so that the projection unit 51 is away from the geomagnetic sensor 31 on the bridge 12, so as to further reduce the electromagnetic interference on the geomagnetic sensor 31.
[0055] In the embodiment, as shown in Figures 1 to 3 The optical unit 52 includes a holographic waveguide, which is used to guide the image light and external light into the human eye. The wearer can normally see the external environment while viewing the motion data information, realizing seamless fusion of virtual images and the real world, improving the clarity and brightness of the display, and reducing interference with the user's vision.
[0056] In the embodiment, as shown in Figures 1 to 3 The AR glasses 100 further include a wearing sensor installed on the temple 20 or the frame 10. The wearing sensor is installed on the lens holder 11 or the temple 20. When the wearing sensor detects that the AR glasses 100 are in contact with the human head, it is judged as a wearing state. When the wearing sensor does not detect contact, it is judged as a non-wearing state. In the non-wearing state, the AR glasses 100 enter a sleep mode to save power. In the wearing state, the AR glasses 100 end the sleep and enter a working state. The wearing sensor not only improves the endurance of the AR glasses 100, but also avoids power waste caused by misoperation.
[0057] In the embodiment, as shown in Figures 1 to 3As shown, the wearing sensor is arranged on the temple 20. On the one hand, the temple 20 is in close contact with the two sides of the human head, and can stably collect the physiological signals of the human body, so as to accurately determine whether the AR glasses are in the wearing state. On the other hand, the position of the temple is relatively concealed. The wearing sensor arranged at this position will not damage the overall appearance of the AR glasses. In addition, since the power module 60 is arranged at the temple position, the wearing sensor can more conveniently obtain power supply, thereby ensuring the continuous and stable work of the wearing sensor. In addition, the wearing sensor is arranged on the temple 20, away from the geomagnetic sensor 31, which can reduce the electromagnetic interference on the geomagnetic sensor 31. The wearing sensor can be a human body proximity sensor, which is used to determine whether it is in contact with the human head to determine the current state as a wearing state or a non-wearing state, thereby realizing the automatic sleep and wake-up functions of the AR glasses 100 and saving power.
[0058] In the embodiment, as shown in The AR glasses 100 further include a communication module, which is installed on the frame 10 or the temple 20 and is used for information transmission with a terminal device. The communication module is installed on the lens holder 11 or the temple 20. The AR glasses 100 can send the collected motion data to the terminal device through the communication module. The APP in the terminal device can acquire, store, analyze, track and display these motion characteristics, thereby providing more comprehensive and in-depth motion analysis and suggestions for the wearer. The AR glasses 100 can also receive instructions from the terminal device, such as the user operating the application program on the terminal device to send instructions to adjust the display brightness of the AR glasses 100, switch the display mode, start a specific function, etc., so that the AR glasses 100 can work according to the user's intention. At the same time, the AR glasses 100 feed back the working state (such as the power, the connection state, etc.) of itself to the terminal device, so that the user can timely understand the status of the AR glasses 100 on the terminal device, so as to perform corresponding operations. In addition, the terminal device can also send device resources (such as map data, music files, etc.) to the AR glasses 100, and use the device resources to enrich the functions of the AR glasses 100, for example, in the AR navigation, the map data is combined to provide more accurate route guidance, and the music in the terminal is played to realize the AR experience of sound and picture synchronization. The terminal device can be a mobile phone, a watch, a tablet computer, etc. In the interaction process between the AR glasses 100 and the terminal device, the transmission mode of the communication module supports wired transmission and wireless transmission, so as to realize the convenient communication between the AR glasses 100 and the terminal device. Preferably, the communication module adopts the wireless transmission mode of the Bluetooth module or the Wi-Fi module, which is convenient for the wearer to use in different scenes. The electronic elements include the communication module.

When technical features in different embodiments are embodied in the same drawing, it can be considered that the drawing discloses a combination of the embodiments involved.

It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the protection scope of the present application.
