Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0075] The following is in conjunction with the appendix Figures 1a to 11 As shown, the wearable device provided in this application will be described in detail through specific embodiments and application scenarios.

[0076] like Figures 2a to 2c , Figures 7a to 7cAs shown in the embodiment of this application, the wearable device includes: a device body 10, a detection module, and a control module. The device body 10 is provided with multiple antennas 20, for example, three antennas 20. The multiple antennas 20 can be spaced apart and can be of the same or different types. The detection module can be located on the device body 10 or in other locations, depending on the specific circumstances. The detection module can be used to detect the relative position and / or attitude of the device body 10 and the reference object 60 at a first moment, and to obtain the relative position and / or attitude of the device body 10 and the reference object 60 at a second moment based on the relative position and / or attitude of the device body 10 and the reference object 60 at the first moment, where the first moment is prior to the second moment. The detection module can obtain the relative position and / or attitude of the device body 10 and the reference object 60 at the first moment based on the relative position and / or attitude of the device body 10 and the reference object 60 at the first moment, as well as the relative motion parameters of the device body 10 and the reference object 60. The motion parameters may include at least one of linear velocity, angular velocity, linear acceleration and angular acceleration. The relative position and / or attitude of the device body 10 and the reference object 60 at the second moment can be predicted by combining the relative rotational speed or at least one of angular velocity, angular velocity acceleration, linear velocity and linear velocity acceleration of the device body 10 and the reference object 60.

[0077] The detection module can be used to detect the relative position and / or attitude of the device body 10 and the reference object 60 at the current moment, and to predict the relative position and / or attitude of the device body 10 and the reference object 60 at the next moment based on the relative position and / or attitude of the device body 10 and the reference object 60 at the current moment. The current moment is before the next moment. The detection module can predict the relative position and / or attitude of the device body 10 and the reference object 60 at the next moment based on the relative position and / or attitude of the device body 10 and the reference object 60 at the current moment. The detection module can obtain the relative position and / or attitude of the device body 10 and the reference object 60 at the next moment based on the current relative position and / or attitude of the device body 10 and the reference object 60, as well as the relative motion parameters of the device body 10 and the reference object 60. The motion parameters can include at least one of linear velocity, angular velocity, linear acceleration, and angular acceleration. The relative rotational speed or at least one of angular velocity, angular velocity acceleration, linear velocity, and linear velocity acceleration of the device body 10 and the reference object 60 can be combined to predict the relative position and / or attitude of the device body 10 and the reference object 60 at the next moment. The detection module can predict the relative position and / or attitude of the device body 10 and the reference object 60 at the next moment. The control module can be used to control the antenna 20, which is close to or radiates towards the reference object, to transmit and receive signals based on the relative position and / or attitude of the device body 10 and the reference object at the second moment. The wearable device can include smart glasses, and the device body 10 can be smart glasses. Multiple antennas 20 can be set on the smart glasses, and the antennas 20 can be set on the frame of the smart glasses. The reference point can be a router or a base station, and the device communicating with the wearable device can be a single router or multiple routers or base stations.

[0078] The reference object can be a router. Multiple antennas 20 on the main body 10 can communicate with the router. When the relative position and / or attitude of the main body 10 and the reference object changes, the antennas on the main body 10 that are close to the router or whose radiation direction is towards the router can be controlled to transmit and receive signals. Communication with the router is achieved through the antennas on the main body 10 that are close to the router or whose radiation direction is towards the router, thus ensuring communication quality and reducing the impact of changes in the relative position and / or attitude of the main body 10 and the reference object on communication quality.

[0079] Wearable devices can be smart glasses, such as Figures 1a to 3bAs shown, the main body 10 of the device may include a glasses body 11 and a wearable part 12. An antenna 20 may be disposed on the glasses body 11 and the wearable part 12. The glasses body 11 may have two glasses displays or lenses. The glasses body 11 is connected to the wearable part 12, which may include a headband to facilitate wearing the glasses. The wearable part can be worn on a person's head so that the lenses of the smart glasses correspond to the person's eyes. The wearable part 12 may include a supporting headband 121, on which the antenna 20 may be disposed. The supporting headband 121 may have a U-shaped structure. The glasses body 11 may be connected to both ends of the supporting headband 121 for easy wearing. A connecting headband 122 may be disposed between the supporting headband 121 and the glasses body 11. The antenna 20 may be disposed on the connecting headband 122. One end of the connecting headband 122 may be connected to the supporting headband 121, and the other end of the connecting headband 122 may be connected to the glasses body 11 to ensure stability during wearing. The headband 121 can be made of a non-elastic material, such as metal or plastic. It possesses sufficient structural strength for stable wear. The connecting headband 121 can be elastic, preventing the wearing part from easily slipping off. The wearing part 12 can be elastic, enhancing comfort and facilitating easy on and off. The wearing part 12 can be a flexible structure, including woven straps, rubber bands, etc., and can be bent to reduce its space requirements during storage. A battery compartment 13 can be installed on the smart glasses, housing batteries. The battery compartment 13 can be located on the main body of the glasses or the wearing part.

[0080] During use, the reference point can be the router. Due to the movement of the wearable device, the relative position and / or orientation of the device and the reference point may change. The user's body or other surrounding objects may obstruct the antenna, and the radiation direction of some antennas may deviate from the target direction. The relative position and / or orientation of the device and the reference point at a second moment can be predicted based on the first moment's relative position and / or orientation. By controlling the antennas that are close to or radiating towards the reference point based on the second moment's relative position and / or orientation, the antennas that are close to or radiating towards the target direction can transmit and receive signals, improving the communication quality between the device's antennas and related devices and reducing the impact of changes in the relative position and / or orientation of the device and the reference point on antenna performance. Antennas for communication with external devices in different directions can be preset based on the coverage of the radiation patterns of multiple antennas in the smart glasses. Based on the relative position and orientation between the smart glasses and the router, during user movement or exercise, the antenna with the optimal radiation pattern in the signal transmission direction between the smart glasses and the router can always be used to communicate with the router, ensuring the communication quality between the smart glasses and the router.

[0081] In some embodiments, at least two antennas 20 have different radiation directions. For example, the device body 10 is provided with three antennas 20, two of which have different radiation directions. The device body 10 is provided with multiple antennas 20, each with a different radiation direction. Changes in the relative position and / or attitude of the device body and a reference object allow antennas closer to or with radiation directions towards the target to transmit and receive signals, improving the communication quality between the antennas of the device body and related devices.

[0082] In the embodiments of this application, the device body 10 has a first positioning antenna. The detection module can be used to detect the relative position and / or attitude of the device body 10 and the reference object 60 at the initial moment based on the signal of the first positioning antenna. The initial moment is before the first moment. The first positioning antenna may include an antenna 20. The first positioning antenna may be composed entirely of multiple antennas 20. For example, the first positioning antenna may be composed of at least three antennas 20. The first positioning antenna may also be composed of antennas 20 and other positioning antennas. The first positioning antenna may also not include antennas 20.

[0083] The detection module is used to obtain the relative position and / or attitude of the device body 10 and the reference object 60 at a first moment based on the initial relative position and / or attitude of the device body 10 and the reference object 60, as well as the relative motion parameters of the device body 10 and the reference object 60. The motion parameters include at least one of linear velocity, angular velocity, linear acceleration, and angular acceleration. For example, the detection module can obtain the relative position and / or attitude of the device body 10 and the reference object 60 at a first moment based on the initial relative position and / or attitude of the device body 10 and the reference object 60, as well as the relative motion parameters of the device body 10 and the reference object 60. The motion parameters may include linear velocity, angular velocity, linear acceleration, and angular acceleration. By obtaining the velocity and acceleration, the relative position and / or attitude of the device body 10 and the reference object 60 at the first moment can be obtained, and the corresponding antenna on the device body 10 can be controlled to transmit and receive signals, reducing the impact of changes in the relative position and / or attitude of the device body 10 and the reference object on the communication quality.

[0084] In embodiments of this application, the detection module is used to obtain the relative position and / or attitude of the device body 10 and the reference object 60 at a second moment based on the relative position and / or attitude of the device body 10 and the reference object 60 at a first moment and the relative motion parameters of the device body 10 and the reference object 60. The motion parameters include at least one of linear velocity, angular velocity, linear acceleration, and angular acceleration. For example, the detection module can obtain the relative position and / or attitude of the device body 10 and the reference object 60 at a second moment based on the relative position and / or attitude of the device body 10 and the reference object 60 at a first moment and the relative motion parameters of the device body 10 and the reference object 60. The motion parameters may include linear velocity, angular velocity, linear acceleration, and angular acceleration. By using velocity and acceleration, the relative position and / or attitude of the device body 10 and the reference object 60 at a second moment can be obtained, and the corresponding antenna on the device body 10 can be controlled to transmit and receive signals, reducing the impact of changes in the relative position and / or attitude of the device body 10 and the reference object on communication quality.

[0085] The relative position and / or attitude between the main body 10 and the reference object 60 can be confirmed using three antennas. The relative position and / or attitude between the main body 10 and the reference object 60 can be determined by ranging and angle measurement. The electromagnetic wave transmission distance can be calculated based on the time difference between the transmitted and reflected signals from the antennas, thus achieving ranging. Angle measurement can be achieved using the phase method based on the antenna signals; one antenna can be shared, and a minimum of three antennas are required to complete angle measurement. During the detection process, the measured real-time linear acceleration / angular acceleration a(t) can be integrated over time to obtain the real-time velocity v(t). Integrating the real-time linear velocity / angular velocity over time yields the real-time position P(t) and motion trajectory. Superimposing the real-time motion trajectory with the initial relative position and / or attitude yields the real-time relative position and / or attitude. When the superimposed real-time relative position and / or attitude moves to the critical point for switching the antenna position and / or attitude, if the motion trend does not slow down or even reverses, the antenna can be switched; if the motion trend slows down or even reverses, the antenna does not need to be switched. The corresponding antenna on the main body 10 can be controlled to transmit and receive signals as needed, thereby reducing the impact of changes in the relative position and / or attitude of the main body 10 and the reference object on communication quality.

[0086] The main body of the device 10 can be smart glasses, and the reference object can be a router. The explanation will be based on displacement in the horizontal plane. Figure 11As shown, when the smart glasses are initially located at position A, the angle φA between the smart glasses and the router is 270°. After moving by a displacement S to position C, the angle φC between the smart glasses and the router is 315°. During this movement, the angle between the smart glasses and the router changes, and the antenna can be switched as needed. When the smart glasses are initially located at position B, the angle φB between the smart glasses and the router is 0°. After moving by a displacement S to position D, the angle φD between the smart glasses and the router is 0°. During this movement, the angle between the smart glasses and the router does not change, so there is no need to switch the antenna. Due to the increased distance, the beamwidth of the radiation pattern can be adjusted as needed. Similarly, if the smart glasses rotate 45° counterclockwise at position C, the 45° angle change caused by the displacement cancels out, and the angle between the smart glasses and the router does not actually change, so there is no need to switch the antenna. If the smart glasses rotate 45° counterclockwise at position D, the angle between the smart glasses and the router changes, and the antenna can be switched as needed. When the initial positions are at positions A and B respectively, the angle changes are different after the same displacement. Therefore, the initial position and / or attitude can be determined. By superimposing the motion trajectory detected and calculated by the detection module on the initial position and / or attitude, the real-time relative position and / or attitude can be obtained, thus determining the position and / or attitude of the router and the smart glasses.

[0087] In the embodiments of this application, such as Figures 3a to 3b As shown, the multiple antennas include a first antenna 201 and a second antenna 202. The number of first antennas 201 and second antennas 202 can be one or more, and the radiation directions of the first antennas 201 and second antennas 202 are different. Figure 3a As shown, a first antenna 201 can be installed on one side of the glasses body 11, and a second antenna 202 can be installed on the other side of the glasses body 11. The second antenna 202 can also be installed on the wearable part 12, such as on the supporting headband 121 or the connecting headband 122. Figure 3b As shown, a second antenna 202 can be installed on the headband 122. The specific locations of the first antenna 201 and the second antenna 202 can be reasonably selected according to the actual situation, as long as the radiation directions of the first antenna 201 and the second antenna 202 are different.

[0088] The control module is used to control the first antenna 201, which is directed towards or radiates towards the reference object 60, to transmit and receive signals when the relative position of the device body 10 and the reference object is in a first position at a first moment; the control module is also used to control the second antenna 202, which is directed towards or radiates towards the reference object 60, to transmit and receive signals when the relative position of the device body 10 and the reference object is in a second position at a second moment, where the first position and the second position are different. For example, if the reference object is a router, when the relative position of the device body 10 and the reference object is in the first position at a first moment, the radiation direction of the first antenna 201 can be towards the router, and there are no obstacles obstructing the connection between the first antenna 201 and the router. When the relative position of the device body 10 and the reference object is in the first position at a first moment, the control module controls the first antenna 201 to transmit and receive signals, resulting in better communication quality between the first antenna 201 and the router. The first position is different from the second position. When the relative position of the device body 10 and the reference object is in the second position at the second moment, the first antenna 201 is blocked by an obstacle, and the radiation direction of the second antenna 202 can be directed towards the router. When there is no obstacle between the second antenna 202 and the router, the control module is used to control the second antenna 202 to transmit and receive signals when the relative position of the device body 10 and the reference object is in the second position at the second moment. At this time, the communication quality between the second antenna 202 and the router is better.

[0089] In some embodiments, such as Figures 3a to 3b As shown, multiple antennas include a first antenna 201 and a second antenna 202. The first antenna 201 and the second antenna 202 have different radiation directions. The control module is used to control the first antenna 201, which is close to or has its radiation direction facing the reference object 60, to transmit and receive signals when the relative attitude between the device body 10 and the reference object is in a first attitude at a first moment. The control module is also used to control the second antenna 202, which is close to or has its radiation direction facing the reference object 60, to transmit and receive signals when the relative attitude between the device body 10 and the reference object is in a second attitude at a second moment. The first attitude is different from the second attitude. The relative attitude between the device body 10 and the reference object can include the relative angle between the device body 10 and the reference object, such as specific parts of the device body 10 facing or away from the reference object, or the device body 10 being in different rotation states, top-down states, or bottom-up states, resulting in different situations for specific parts of the device body 10 relative to the reference object.

[0090] For example, the reference point can be a router. When the relative position of the device body 10 and the reference point is in a first-moment orientation, the radiation direction of the first antenna 201 can be towards the router, and the radiation direction of the second antenna 202 can be away from the router. The control module controls the first antenna 201 to transmit and receive signals when the relative position of the device body 10 and the reference point is in the first-moment orientation. At this time, the communication quality between the first antenna 201 and the router is relatively good. When the relative position of the device body 10 and the reference point is in a second-moment orientation, the radiation direction of the first antenna 201 can be away from the router, and the radiation direction of the second antenna 202 can be towards the router. The control module controls the second antenna 202 to transmit and receive signals when the relative position of the device body 10 and the reference point is in the second-moment orientation. At this time, the communication quality between the second antenna 202 and the router is relatively good.

[0091] Optionally, such as Figure 8 As shown, the wearable device also includes a control handle 30, which communicates with the device body 10 and can be wirelessly connected. The control handle 30 has multiple third antennas, which can be spaced apart. For example, the control handle 30 can be elongated, with third antennas at both ends. The control module controls the third antennas on the control handle 30 to transmit and receive signals based on the relative position and / or orientation of the control handle 30 and the device body 10, either close to or radiating towards the device body 10. When the relative position and / or orientation of the control handle 30 and the device body 10 are different, the different third antennas will have different relative positions and / or orientations relative to the device body 10. The control module can control the third antennas close to or radiating towards the device body 10 to transmit and receive signals based on the relative position and / or orientation of the control handle 30 and the device body 10, thereby improving communication between the control handle 30 and the device body 10.

[0092] Optionally, a position detector can be installed on the control handle 30. The position detector detects the relative position between the control handle 30 and the device body 10. The position detector may include a ranging radar, an accelerometer, an electronic compass, etc. By detecting the relative position between the control handle 30 and the device body 10, different antennas can be controlled to transmit and receive signals based on the relative position, enabling better communication between the antenna and the router. Optionally, an attitude detector can be installed on the control handle 30. The attitude detector detects the relative attitude between the control handle 30 and the device body 10. The attitude detector may include a gyroscope, an electronic compass, etc. By detecting the relative attitude between the control handle 30 and the device body 10, different antennas can be controlled to transmit and receive signals based on the relative attitude, enabling better communication between the antenna and the router. The relative motion trajectory between the control handle 30 and the device body 10 can be detected by sensors, and the relative position and / or attitude between the control handle 30 and the device body 10 at the current and next moment during user operation can be calculated and predicted.

[0093] Optionally, the control module is used to control the third antenna on the control handle 30 that is close to or radiates towards the device body 10 to transmit and receive signals. For example, the control handle 30 can be elongated, and each end of the control handle 30 can be equipped with a third antenna. When one end of the control handle 30 is facing or close to the device body 10, the control module can control the third antenna on that end to transmit and receive signals; when the other end of the control handle 30 is facing or close to the device body 10, the control module can control the third antenna on that other end to transmit and receive signals, so that the control handle 30 and the device body 10 can communicate well through the third antenna. Depending on the relative position and / or attitude of the control handle 30 and the device body 10, the third antenna with the best communication effect on the control handle 30 can always be used for communication during user movement or motion, ensuring the communication quality between the smart glasses and the control handle 30.

[0094] In some embodiments, a detection module may be disposed on the control handle 30, or it may be disposed at other locations, the specific location of which can be selected according to actual conditions. The detection module can be used to detect the relative position and / or attitude of the control handle 30 and the device body 10 at a third moment, and can be used to obtain the relative position and / or attitude of the control handle 30 and the device body 10 at a fourth moment based on the relative position and / or attitude of the control handle 30 and the device body 10 at the third moment, wherein the third moment is prior to the fourth moment. The detection module can obtain the relative position and / or attitude of the control handle 30 and the device body 10 at a fourth moment based on the relative position and / or attitude of the control handle 30 and the device body 10 at the third moment and the relative motion parameters of the control handle 30 and the device body 10. The motion parameters may include at least one of linear velocity, angular velocity, linear acceleration, and angular acceleration. The control module can be used to control the third antenna on the control handle 30 to transmit and receive signals in the direction of proximity or radiation toward the device body 10 according to the relative position and / or attitude of the control handle 30 and the device body 10 at the fourth moment. The third antenna with the best communication quality on the control handle 30 can be used for communication to ensure the communication quality between the control handle 30 and the device body 10.

[0095] The detection module can be used to detect the relative position and / or attitude of the control handle 30 and the device body 10 at the current moment, and can be used to predict the relative position and / or attitude of the control handle 30 and the device body 10 at the next moment based on the relative position and / or attitude of the control handle 30 and the device body 10 at the current moment, where the current moment is before the next moment. The detection module obtains the relative position and / or attitude of the control handle 30 and the device body 10 at the next moment based on the relative position and / or attitude of the control handle 30 and the device body 10 at the current moment and the relative motion parameters of the control handle 30 and the device body 10. The motion parameters may include at least one of linear velocity, angular velocity, linear acceleration and angular acceleration. The relative position and / or attitude of the control handle 30 and the device body 10 at the next moment can be predicted by combining at least one of the relative rotational speed, angular velocity acceleration, linear velocity and linear velocity acceleration of the control handle 30 and the device body 10. The detection module predicts the relative position and / or attitude of the control handle 30 and the device body 10 at the next moment. The control module can be used to control the third antenna on the control handle 30 to transmit and receive signals in the direction of proximity or radiation toward the device body 10 according to the relative position and / or attitude of the control handle 30 and the device body 10 at the next moment. The third antenna with the best communication quality on the control handle 30 can be used for communication to ensure the communication quality between the control handle 30 and the device body 10.

[0096] In some embodiments, the control handle 30 has a second positioning antenna, and the detection module is used to detect the relative position and / or attitude of the control handle 30 and the device body 10 at the start time according to the signal of the second positioning antenna. The start time is before the third time. The second positioning antenna may include a third antenna. The second positioning antenna may be composed entirely of multiple third antennas. For example, the second positioning antenna may be composed of at least three third antennas. The second positioning antenna may also be composed of a third antenna and other positioning antennas. The second positioning antenna may also not include a third antenna.

[0097] The detection module is used to obtain the relative position and / or attitude of the control handle 30 and the device body 10 at a third moment based on the relative position and / or attitude of the control handle 30 and the device body 10 at the initial moment, as well as the relative motion parameters of the control handle 30 and the device body 10. The motion parameters may include at least one of linear velocity, angular velocity, linear acceleration, and angular acceleration. For example, the motion parameters may include linear velocity, angular velocity, linear acceleration, and angular acceleration. When the relative position and / or attitude of the control handle 30 and the device body 10 changes, the third antenna, which is close to the device body 10 or whose radiation direction is towards the device body 10, can be controlled to transmit and receive signals, so as to enable better communication between the control handle 30 and the device body 10.

[0098] In the embodiments of this application, the detection module is used to obtain the relative position and / or attitude of the control handle 30 and the device body 10 at a fourth moment based on the relative position and / or attitude of the control handle 30 and the device body 10 at a third moment and the relative motion parameters of the control handle 30 and the device body 10. The motion parameters include at least one of linear velocity, angular velocity, linear acceleration, and angular acceleration. For example, the motion parameters may include linear velocity, angular velocity, linear acceleration, and angular acceleration. When the relative position and / or attitude of the control handle 30 and the device body 10 changes, the third antenna, which is close to the device body 10 or whose radiation direction is towards the device body 10, can be controlled to transmit and receive signals, so that the control handle 30 and the device body 10 can communicate better. The method for obtaining the relative position and / or attitude of the control handle 30 and the device body 10 can be the same as the method for obtaining the relative position and / or attitude of the device body 10 and the reference object 60 described above.

[0099] In embodiments of this application, the plurality of third antennas may include a fourth antenna and a fifth antenna, wherein the fourth antenna and the fifth antenna have different radiation directions on the control handle 30. The control module is used to control the fourth antenna, which is close to or has its radiation direction directed toward the device body 10, to transmit and receive signals when the relative position of the control handle 30 and the device body 10 at a third moment is in a third position; the control module is also used to control the fifth antenna, which is close to or has its radiation direction directed toward the device body 10, to transmit and receive signals when the relative position of the control handle 30 and the device body 10 at a fourth moment is in a fourth position, wherein the third position and the fourth position are different.

[0100] For example, the control handle 30 can be elongated, with a fourth antenna at one end and a fifth antenna at the other. When the relative position of the control handle 30 and the device body 10 is in the third position at a third moment, with one end of the control handle 30 facing or close to the device body 10, the control module can control the fourth antenna at one end of the control handle 30 to transmit and receive signals, enabling better communication between the control handle 30 and the device body 10 via the fourth antenna. Similarly, when the relative position of the control handle 30 and the device body 10 is in the fourth position at a fourth moment, with the other end of the control handle 30 facing or close to the device body 10, the control module can control the fifth antenna at the other end of the control handle 30 to transmit and receive signals, again enabling better communication between the control handle 30 and the device body 10 via the fifth antenna. During user movement or motion, the third antenna on the control handle 30, which provides the best communication performance, can always be used for communication based on the relative position of the control handle 30 and the device body 10, ensuring the communication quality between the control handle 30 and the device body 10.

[0101] Optionally, the multiple third antennas may include a fourth antenna and a fifth antenna, wherein the fourth antenna and the fifth antenna have different radiation directions on the control handle 30. The control module is used to control the fourth antenna, which is close to or has its radiation direction toward the device body 10, to transmit and receive signals when the relative attitude between the control handle 30 and the device body 10 is in a third attitude; the control module is also used to control the fifth antenna, which is close to or has its radiation direction toward the device body 10, to transmit and receive signals when the relative attitude between the control handle 30 and the device body 10 is in a fourth attitude, wherein the third attitude and the fourth attitude are different.

[0102] For example, one end of the control handle 30 is equipped with a fourth antenna, and the other end is equipped with a fifth antenna. When the relative attitude between the control handle 30 and the device body 10 is in the third position, with one end of the control handle 30 facing or close to the device body 10, the control module can control the fourth antenna located at one end of the control handle 30 to transmit and receive signals, enabling better communication between the control handle 30 and the device body 10 via the fourth antenna. Similarly, when the relative attitude between the control handle 30 and the device body 10 is in the fourth position, with the other end of the control handle 30 facing or close to the device body 10, the control module can control the fifth antenna located at the other end of the control handle 30 to transmit and receive signals, also enabling better communication between the control handle 30 and the device body 10 via the fifth antenna. During user movement or motion, the third antenna with the best communication performance on the control handle 30 can always be used for communication based on the relative attitude between the control handle 30 and the device body 10, ensuring the communication quality between the control handle 30 and the device body 10. In some embodiments, the control module is used to control and adjust the phase difference between at least two of the multiple antennas according to the relative position and / or attitude of the device body 10 and the reference object at a second moment, which can change the radiation direction of the antennas and make the radiation direction of the antennas face the router so that the antennas can communicate better with the router.

[0103] Optionally, such as Figure 9 As shown, at least one antenna 20 includes multiple antenna elements 24, each with a different radiation direction. The control module controls the antenna elements 24 to transmit or receive signals based on their relative position and / or attitude relative to the reference object at a second moment. The antenna 20 can be an array antenna. By controlling the transmission and reception of signals by different antenna elements 24, one or more antenna elements 24 can form an array antenna, allowing the array antenna to have different radiation directions. This allows the antenna to radiate towards the router, enabling better communication between the antenna and the router. Figure 9 In the diagram, antenna element 24 in region d1 can form an array antenna, and c1 represents the radiation pattern of the array antenna formed by antenna element 24 in region d1. Antenna element 24 in region d2 can form an array antenna, and c2 represents the radiation pattern of the array antenna formed by antenna element 24 in region d2. The radiation patterns of array antennas formed by different antenna elements 24 are different, and different antenna elements 24 can be selected according to actual needs to realize the transmission and reception of signals.

[0104] The antenna of the smart glasses can be an array antenna composed of antenna elements 24. When the smart glasses detect changes in their position and attitude relative to the router, causing a change in the angle between the smart glasses and the router, the maximum radiation direction and beamwidth of the array antenna can be adjusted by adjusting the phase of the array elements or reselecting the antenna elements that make up the array antenna, thereby achieving array antenna pattern reconstruction or array switching. Based on the relative position and / or attitude between the smart glasses and the router, during user movement or motion, the maximum radiation direction of the array antenna on the smart glasses can be adjusted by adjusting the phase of the antenna elements or reselecting the antenna elements that make up the array antenna, ensuring that the maximum radiation direction of the array antenna on the smart glasses always points towards the router. The beamwidth of the array antenna can be adjusted according to the distance between the smart glasses and the router to ensure communication quality between the smart glasses and the router.

[0105] Optionally, such as Figure 1d As shown, the detection module may include a position detector 40, which is used to detect the relative position of the device body 10 and a reference object. The position detector 40 may include a ranging radar, an accelerometer, an electronic compass, etc. By detecting the relative position of the device body 10 and the reference object, different antennas can be controlled to transmit and receive signals based on the relative position of the device body 10 and the reference object, enabling better communication between the antenna and the router. Optionally, as... Figure 1d As shown, the detection module may include an attitude detector 50, which is used to detect the relative attitude of the device body 10 and a reference object. The attitude detector 50 may include a gyroscope, an accelerometer, an electronic compass, etc. The attitude detector 50 can detect the relative attitude of the device body 10 and the reference object, so as to control different antennas to transmit and receive signals according to the relative attitude of the device body 10 and the reference object, enabling better communication between the antenna and the router. The number of position detectors 40 and attitude detectors 50 can be one or more. The position detectors 40 and attitude detectors 50 can be located at any position within the glasses body 11, such as on the circuit board, the shell of the glasses body 11, the headband, the battery compartment, etc. By detecting the movement trend of the device body 10 through the position detectors 40 and attitude detectors 50, combined with the initial relative position and attitude, the relative position and attitude between the smart glasses and the external device at the current and next moment can be calculated. Based on the obtained relative position and angle information at the current and next moment, the appropriate antenna can be selected in advance to communicate with the external device.

[0106] In some embodiments of this application, the detection module may include a processing module. The position detector 40 in the detection module can detect the relative position of the device body 10 and the reference object 60 at a first moment. The processing module in the detection module can obtain the relative position of the device body 10 and the reference object 60 at a second moment based on the relative position of the device body 10 and the reference object 60 at the first moment. Based on the relative position of the device body 10 and the reference object 60 at the first moment, the processing module in the detection module can combine the linear velocity and acceleration of the device body 10 to predict the relative position of the device body 10 and the reference object 60 at the second moment, thus obtaining the relative position of the device body 10 and the reference object 60 at the second moment. The attitude detector 50 in the detection module can detect the relative attitude of the device body 10 and the reference object 60 at the first moment. The processing module in the detection module can obtain the relative attitude of the device body 10 and the reference object 60 at the second moment based on the relative attitude of the device body 10 and the reference object 60 at the first moment. Based on the relative attitude of the device body 10 and the reference object 60 at the first moment, the processing module in the detection module can combine the angular velocity and acceleration of the angular velocity of the device body 10 to predict the relative attitude of the device body 10 and the reference object 60 at the second moment, and obtain the relative attitude of the device body 10 and the reference object 60 at the second moment.

[0107] In some other embodiments of this application, the detection module may include a processing module. The position detector 40 in the detection module can detect the relative position of the control handle 30 and the device body 10 at a third moment. The processing module in the detection module can obtain the relative position of the control handle 30 and the device body 10 at a fourth moment based on the relative position of the control handle 30 and the device body 10 at the third moment. Based on the relative position of the control handle 30 and the device body 10 at the third moment, the processing module in the detection module can combine the linear velocity and acceleration of the control handle 30 to predict the relative position of the control handle 30 and the device body 10 at the fourth moment, thus obtaining the relative position of the control handle 30 and the device body 10 at the fourth moment. The attitude detector 50 in the detection module can detect the relative attitude of the control handle 30 and the device body 10 at the third moment. The processing module in the detection module can obtain the relative attitude of the control handle 30 and the device body 10 at the fourth moment based on the relative attitude of the control handle 30 and the device body 10 at the third moment. Based on the relative position of the control handle 30 and the device body 10 at the third moment, the processing module in the detection module can combine the angular velocity and acceleration of the control handle 30 to predict the relative attitude of the control handle 30 and the device body 10 at the fourth moment, and obtain the relative attitude of the control handle 30 and the device body 10 at the fourth moment.

[0108] Optionally, the wearable device may include smart glasses, and the reference object may include a router. The relative position and / or attitude of the smart glasses and the router control the corresponding antennas to transmit and receive signals, thereby improving the communication quality between the smart glasses and the router. The wearable device may include watches, bracelets, glasses, clothing, belts, shoes, and other wearable devices, while the reference object may include base stations, routers, transceivers, mobile phones, tablets, computers, power supplies, and other reference objects.

[0109] Antenna 20 may include a Bluetooth (BT) antenna, a WiFi antenna, or a multi-band millimeter-wave (mmW) antenna, or other functional antennas such as ultra-wideband (UWB) antennas. Antennas with different functions can be combined; for example, Bluetooth and WiFi antennas can be time-division multiplexed, or multiple functions can be implemented on the same antenna or array using a multi-band antenna. The antenna used to determine the initial relative position of the device body 10 with a reference object can be an antenna used for data communication between the smart glasses and the router, or other antennas used for positioning such as multi-band millimeter-wave ranging radar or ultra-wideband antennas. The number of antennas, their layout, radiation pattern shape, and the location of antenna switching can be adjusted according to actual conditions. For multiple-input multiple-output (MIMO) systems, one or more antennas or arrays with the best directivity in the direction pointing towards the router can be used simultaneously as communication antennas.

[0110] In the embodiments of this application, the device body 10 is provided with multiple antennas, for example, the device body 10 is provided with three antennas, and the multiple antennas can be arranged at intervals. The device body 10 may be provided with antenna 21 (ANT2), antenna 22 (ANT1), and antenna 23 (ANT3). The control module can be used to control the corresponding antenna 20 to transmit and receive signals according to the relative position and / or attitude of the device body 10 and the reference object at a second moment. The device body 10 can be smart glasses. The front view and top view of the antenna radiation patterns of antenna 22, antenna 21, and antenna 23 can be as follows. Figure 4a and Figure 4b As shown in the diagram. a1 represents the radiation pattern of antenna 21, a2 represents the radiation pattern of antenna 22, and a3 represents the radiation pattern of antenna 23. The antenna radiation pattern of antenna 22 points to the lower left of the user's head, the antenna radiation pattern of antenna 21 points to the lower right of the user's head, and the antenna radiation pattern of antenna 23 points to the top of the user's head.

[0111] Smart glasses can be equipped with sensors such as accelerometers and gyroscopes to detect linear velocity, linear acceleration, angular velocity, or rotational speed and angular acceleration. During user movement, the smart glasses record the acceleration data detected by the accelerometer and the angular velocity detected by the gyroscope. Acceleration integration allows for the calculation of the smart glasses' trajectory and their current and next relative positions with the router. Angular velocity integration yields the current and next attitude of the smart glasses.

[0112] The wearable device is smart glasses. After the smart glasses are powered on, ANT1, ANT2, and ANT3 are used to determine the relative position between the router and the smart glasses, establishing a relative coordinate system. Since the router's position is relatively fixed, the router's position is used as the origin of the coordinate system for explanation: the projection of the line connecting the router and the smart glasses onto the horizontal plane is set as the X-axis, the vertical axis passing through the router is set as the Z-axis, and the axis passing through the router and perpendicular to the XoZ plane is set as the Y-axis.

[0113] like Figure 5 As shown, taking the initial position of the smart glasses at point P0 as an example, the router 60 is located below the front of the user's head. At this time, the angle θ0 between the smart glasses and the router 60 can be calculated based on the horizontal and vertical distances between the smart glasses and the router 60 detected when the device is powered on, and θ < 90°, φ0 = 90°. The smart glasses can choose ANT1 to communicate with the router.

[0114] like Figure 5 As shown, the process of the smart glasses first moving left from P0 and then moving down to Pi:

[0115] During horizontal movement: the angle φ first increases from 90°, while the angle θ remains unchanged. The smart glasses can switch from ANT1 to ANT2 and select ANT2 to communicate with the router.

[0116] During the downward movement: the φ angle remains unchanged while the θ angle continues to increase. When the θ angle = 90° and there is a continuous downward movement trend, the smart glasses switch from ANT2 to ANT3, and can choose ANT3 to communicate with the router.

[0117] like Figure 6a As shown, when the tilt angle of the smart glasses changes, the angular velocity detected by the gyroscope can be used to correct the angle between the smart glasses and the router. For example, when the user is at position Pi looking up or down, the angle θ(θ+δθi) decreases when looking up. When θ = 90° and the user continues to tilt their head up, the smart glasses will actively select ANT2 to communicate with the router; when the user is looking down, θ increases, and the user will always use ANT3 to communicate with the router.

[0118] like Figure 6bAs shown, when the azimuth angle of the smart glasses changes, for example, when the user rotates their head at position Pi, the angle φ (φ-δφi) increases when rotating counterclockwise and decreases when rotating clockwise. If θ>90°, the smart glasses can always use the ANT3 antenna to communicate with the router; if θ≤90°, the smart glasses can then select either ANT1 or ANT2 as the antenna for communication with the router based on the actual angle of φ, and can switch between different antennas for communication as needed.

[0119] Based on the pre-tested radiation patterns of ANT1, ANT2, and ANT3 antennas, the optimal communication angles between each antenna and the router can be preset, allowing for the selection of the most suitable antenna at different angles. For example, when θ ≤ 90°, 0° < φ ≤ 90°, or 270° < φ ≤ 360°, the ANT1 antenna can be used to communicate with the router; when θ ≤ 90°, 90° < φ ≤ 270°, the ANT2 antenna can be used; and when θ > 90°, the ANT3 antenna can be used.

[0120] An accelerometer and a gyroscope can be integrated into the control handle 30 that accompanies the smart glasses to detect the movement trajectory and attitude of the control handle 30. The smart glasses integrate two antennas 20 for communication with the control handle 30. Antenna 20 (ANT4) can be mounted on the main body 11 of the glasses, for example, in the middle of the main body 11, or antenna 20 (ANT5) can be mounted on the support headband 121 of the wearing area. The positions and radiation patterns of ANT4 and ANT5 are shown below.
