Wherein, the number of antennas in each device in the figure is only a schematic example, which is not limited in this application. The antenna in the earphone box sends a Bluetooth signal, and the Bluetooth signal is transmitted in the air. For the earphone, after the Bluetooth signal is transmitted through the air, it can be seen as a plane wave.

Referring to Figure 3b, take two antennas in the headset: antenna 1 and antenna 2 as an example. Specifically, there may be a time difference Δt between the time when the antenna 1 and the antenna 2 receive the Bluetooth signal. It can be understood that after the antenna 1 receives the Bluetooth signal and is separated by Δt, the antenna 2 receives the Bluetooth signal. Based on the following formula, the earphone can calculate the angle between it and the earphone box.

d×cosθ=c×Δt (1)

Among them, θ is the angle between the earphone box and the earphone. d is the distance between antenna 1 and antenna 2, and c is the propagation speed of the Bluetooth signal in the air.

(2) AOD calculation method

Fig. 4 shows the specific process of adopting the AOD calculation method. Referring to Fig. 4a, the earphone includes one antenna, and the earphone box includes multiple antennas. Wherein, the number of antennas in each device in the figure is only a schematic example, which is not limited in this application. Each antenna in the earphone box sends a Bluetooth signal, and the Bluetooth signal is transmitted in the air. For the earphone, after the Bluetooth signal is transmitted through the air, it can be regarded as a plane wave.

Referring to Fig. 4b, two antennas in the earphone box: antenna 1 and antenna 2 are taken as an example. Specifically, the antenna 1 and the antenna 2 send Bluetooth signals, and the antenna of the headset receives the Bluetooth signal sent by the antenna 1, and receives the Bluetooth signal sent by the antenna 2 after a distance of Δt. The earphone can calculate the angle between the earphone and the earphone box based on formula (1). Optionally, the earphone can obtain the distance d between the antenna 1 and the antenna 2 before or during the detection. For example, the Bluetooth signal sent by the headset box may include the distance d between the antenna 1 and the antenna 2.

Optionally, in this application, in order to reduce the device pressure of the headset, the headset may send the parameters required for calculation to other terminals, such as a mobile phone, so as to calculate the included angle through the mobile phone. In an example, in the calculation method based on AOA, the headset can send the distance d and Δt between antenna 1 and antenna 2 in the headset to the mobile phone, so that the mobile phone can calculate based on formula (1) and the acquired parameters The angle between the earphone and the earphone box. In another example, in the AOD-based calculation method, the headset can send Δt to the mobile phone, where the mobile phone will also obtain the distance d between the antenna 1 and the antenna 2 in the headset box from the headset box side, and based on the formula ( 1) Calculate the angle between the earphone and the earphone box with the acquired parameters.

It should be noted that, in this application, a Bluetooth signal is taken as an example for description. In other embodiments, other wireless signals, such as wifi signals, can also be used as sources for locating wearable devices. The specific implementation is the same as The Bluetooth signals are the same, so this application will not repeat them one by one.

Several specific embodiments are used below to describe in detail the technical solutions of the foregoing method embodiments.

scene one

Referring to FIG. 5, it exemplarily shows a schematic diagram of an application scenario, which includes a computer, a TV, a headset box, and a headset. The earphone box can be placed anywhere in the room where the computer and the TV are located. The technical solution of the present application will be described in detail below with reference to FIG. 5. In conjunction with FIG. 5, FIG. 6 is a schematic flowchart of a method for positioning a wearable device in an embodiment of this application. In FIG. 6:

Step 101: Connect the earphone to the computer, and determine the first initial angle between the earphone and the earphone box.

Specifically, in this embodiment, as shown in FIG. 7a, the user wears a headset, and the user's head (specifically, the face) faces the computer (specifically, the computer screen), and controls the headset to connect to the computer. The connection between the headset and the computer can refer to the existing technology, which is not limited in this application.

After the headset is successfully connected to the computer, the Bluetooth signal sent by the headset box can be received. Optionally, in this application, the earphone box may send a Bluetooth signal after receiving the trigger signal sent by the earphone, or after the earphone box receives the trigger signal sent by other devices such as mobile phones, to reduce the power consumption of the earphone box . In an example, the trigger signal can be controlled and triggered by the user. For example, the user can control the computer to make the computer send the trigger signal to the earphone box. In another example, after the headset is successfully connected to the computer, the trigger signal can be triggered to be sent to the headset box.

Specifically, after the headset receives the Bluetooth signal sent by the headset box, it can calculate the angle between the headset and the headset box based on the AOA calculation method, AOD calculation method or other calculation methods described above. For specific calculation methods, please refer to Above, I won’t go into details here. Referring to Figure 7a, in this embodiment, the angle between the user’s right earphone and the earphone box is taken as the angle between the pair of earphones and the earphone box. For example, when the user faces the computer, the angle between the earphone and the earphone box is The included angle between is θ1, and in this embodiment, θ1 is 30°.

In this embodiment, after the headset obtains θ1, the included angle is determined as the first initial included angle when connecting to the computer, and the corresponding relationship between the connection event 1 and the included angle is recorded. Specifically, connection event 1 means that the headset is connected to the computer, and the corresponding included angle is θ1 (30°). Exemplarily, when the headset records a connection event, the connection event may be marked with the identification information of the computer. The identification information may be the IP address information of the computer or the device name of the computer, etc., which is not limited by this application.

It should be noted that the connection described in this application, such as the connection of a headset to a computer, refers to a wireless communication connection between the headset and the computer, that is, the headset and the computer can exchange signaling or data through a wireless link after being connected. It should be further noted that the included angle between the earphone and the earphone box in this embodiment refers to the included angle between the earphone worn on the user's right ear and the earphone box.

Step 102: Connect the earphone to the TV, and determine the second initial angle between the earphone and the earphone box.

Specifically, in this embodiment, as shown in FIG. 7b, the user wears earphones, and the user's head (specifically, the face) faces the TV (specifically, the TV screen), and controls the earphone to connect to the TV. The connection mode of the earphone and the TV can refer to the existing technology, which is not limited in this application.

After the headset is successfully connected to the TV, the Bluetooth signal sent by the headset box can be received. The earphone can obtain the included angle θ2 between the earphone and the earphone box based on the received Bluetooth signal. Illustratively, in this embodiment, θ2 is 120°.

In this embodiment, after the headset obtains θ2, the included angle is determined as the second initial included angle when the TV is connected, and the corresponding relationship between the connection event 2 and the included angle is recorded. Specifically, connection event 2 refers to the connection of the headset to the TV, and the corresponding included angle is θ2 (120°). Exemplarily, when the headset records a connection event, the connection event may be marked with the identification information of the TV, and the identification information may be the IP address information of the TV or the device name of the TV, etc., which is not limited in this application.

Step 103: The earphone obtains the angle between the earphone and the earphone box, determines the corresponding connection event, and connects to the corresponding device.

Specifically, in this embodiment, the earphone can monitor the angle between the earphone and the earphone box in real time. For example, if the headset is currently connected to the computer screen, that is, the user is currently facing the computer, and then the user wants to connect to the TV through the headset to receive TV audio, the user can turn his head to the TV screen, that is, as shown in Figure 7b, the headset detects the headset The included angle between the earphone box and the earphone box is 120°. The earphone can match the locally recorded connection event and the associated relationship between the included angle based on the included angle, and when the included angle is 120°, the corresponding connection event is Connection event 2, that is, the headset is connected to the TV. The headset can be disconnected from the computer, and can be connected to the TV based on the stored connection parameters, and receive audio data sent by the TV.

Similarly, if the user turns his head to the computer, after the headset detects that the included angle between the headset and the headset box is 30°, the headset can match the included angle with the correlation between the locally recorded connection event and the included angle , And when the included angle is 30°, the corresponding connection event is connection event 1, that is, the headset is connected to the computer. The headset can be disconnected from the TV, and can be connected to the computer based on the stored connection parameters, and receive audio data sent by the computer.

In a possible implementation manner, an included angle range may be set in the earphone, and the included angle range allows the included angle between the earphone and the earphone box to be confirmed as conforming to a certain initial included angle when the included angle is within the range. The setting of the included angle range can be set according to actual parameters, which is not limited in this application. Exemplarily, in this embodiment, the included angle range can be set to 30°, that is, when the included angle between the earphone and the earphone box is between 0° and 60°, it can be regarded as the difference between the earphone and the earphone box. The angle between the two is consistent with the first initial angle, that is, the headset can be connected to the computer. When the angle between the earphone and the earphone box is between 90° and 150°, it can be considered that the angle between the earphone and the earphone box meets the second initial angle, that is, the earphone can be connected to the TV.

In a possible implementation, if the included angle between the earphone and the earphone box exceeds the range of a certain initial included angle, but has not yet met the range of other initial included angles, in one example, the earphone can still remain with the currently connected device Connect until it connects to the next device. For example, the headset is currently connected to the computer. During the user's rotation, the headset obtains an angle of 80° between the headset and the headset box, which has exceeded the range of the first initial angle (0° to 60°) , But it has not yet met the range of the second initial angle (90° to 150°), the headset can remain connected to the computer, and after meeting the range of the second initial angle, disconnect from the computer and connect to the TV . In another example, if the included angle between the earphone and the earphone box does not meet any initial included angle range within the first preset time period, the earphone can be disconnected from the currently connected device. It should be noted that the purpose of setting the first preset duration is to prevent the headset from being repeatedly connected to the same device in a short time. For example, the first preset duration can be 1 minute, and the preset duration can be set according to actual needs. This application is not limited.

In another possible implementation manner, a second preset duration may be set in the earphone, and the preset duration is used to prevent the ping-pong effect. For example, in this embodiment, after the earphone detects that the included angle between the earphone and the earphone box satisfies the range of the first initial included angle, if the included angle between the earphone and the earphone box still satisfies the first initial angle within the second preset time period, In the range of an initial angle, the headset is connected to the computer. It should be noted that the second preset duration can be set according to actual needs, for example, it can be set to 3s, which is not limited in this application.

In another possible implementation manner, if the position of the earphone box moves, the user can reset the correspondence between the connection event recorded in the earphone and the included angle, that is to say, recycle step 101 and step 101. 102.

Optionally, in this application, the sequence between step 101 and step 102 can be replaced, which is not limited in this application.

It should be noted that in this scenario, only the connection between the headset and two devices is used as an example. In fact, the headset can be connected to multiple devices, and the corresponding relationship between the connection event and the included angle is recorded, so as to achieve Automatic connection of the headset and the device.

In a possible implementation manner, the technical solution of the present application can also be used to correct the relative position of the positioning device in space.

Referring to FIG. 8, it exemplarily shows a schematic diagram of an application scenario, and the application scenario includes smart glasses and a glasses case. The glasses case can be placed at any position in the room where the smart glasses are located. The technical solution of the present application will be described in detail below with reference to FIG. 8.

Specifically, the user wears smart glasses, and after the smart glasses detect that they are successfully worn, they can obtain the orientation of the smart glasses in space based on their built-in compass and other devices, which specifically refers to the spatial orientation the user faces after wearing the smart glasses. However, due to the inaccuracy of the spatial orientation, for example, smart glasses can only judge the orientation of the spatial orientation in eight directions: east, south, west, north, southeast, northeast, southwest, and northwest. For scenes that require accurate orientation, for example, a user wears smart glasses to enjoy paintings in an art gallery. The smart glasses can be positioned through the spatial direction to determine the content and introduction of the corresponding paintings to be displayed. In this scenario, it is necessary to further correct the spatial orientation of the smart glasses in order to accurately position the smart glasses in the space.

Exemplarily, as shown in FIG. 8, the smart glasses can acquire the included angle between the smart glasses and the glasses case, and the method for acquiring the included angle can be referred to the above, and will not be repeated here. The smart glasses can determine the relative direction of the smart glasses in space by combining the acquired spatial orientation of the smart glasses. For example, the smart glasses obtain the northeast direction of the space they are facing through the compass, and the user sets the glasses case in the north wind direction. Based on the angle between the glasses case and the smart glasses, the smart glasses can determine that they are currently in space. The relative direction is 30° north east. Applied to the scene of an art museum, smart glasses can preset the specific spatial orientation of each painting and the corresponding content, introduction and other information. When the smart glasses obtain the direction they are facing 30° north east, that is to say, the user When the current painting faces 30° north east, the content and introduction of the painting corresponding to that orientation can be displayed.

In summary, in this application, users can use devices that are readily available, such as earphone boxes and/or glasses boxes as beacon sources, to locate earphones and/or smart glasses and other wearable devices to obtain wearables The orientation of the device. Optionally, in this application, any device such as an earphone box and/or a glasses box is used as a beacon source, which has the advantages of good mobility and convenience compared with the fixed beacon source in the prior art.

Exemplarily, referring to FIG. 12, the mobile phone may display the accurate position of the earphone on the screen of the mobile phone after acquiring the accurate position information of the earphone. The user can find the headset based on the exact location displayed by the mobile phone.

It should be noted that, in this embodiment, the accurate position of the earphone can also be understood as the relative position between the earphone and the mobile phone. Exemplarily, as shown in FIG. 12, the mobile phone can convert the acquired accurate position information of the headset into the display mode in FIG. 12 based on the compass. The display mode in FIG. 12 is only a schematic example, and this application will not make this limited.
