Before describing the technical solution of the embodiment of the present application, an application scenario of the embodiment of the present application is first described with reference to the drawings. Referring to fig. 1, a schematic view of an application scenario provided in the embodiment of the present application is shown. The application scene comprises an earphone box and earphones.

In the present application, only the earphone box is used as a beacon source, and the earphone is used as a positioning device. Illustratively, the earphone box is an earphone box with a charging function, or an active device, and has a wireless communication capability.

In conjunction with the above schematic application scenario shown in fig. 1, a specific embodiment of the present application is described below:

specifically, in the present application, the earphone box serves as a beacon source and can send out a bluetooth signal, and it can also be understood that the earphone box sends bluetooth broadcast data (or a bluetooth broadcast packet). The wearable device, such as an earphone, can receive the bluetooth signal that the earphone box sent, and respond to the bluetooth signal received, calculate the contained angle between earphone and the earphone box. The specific calculation method will be explained in the following examples.

In a possible implementation manner, the included angle between the earphone and the earphone box may refer to an included angle on a horizontal plane parallel to the ground plane, and as shown in fig. 2a, an exemplary included angle between the earphone and the earphone box is shown in a schematic diagram. Referring to fig. 2b, when the earphone is rotated to the left position in the figure, the angle between the earphone and the earphone box is θ 1, for example, 30 °, and when the earphone is rotated to the right position in the figure, the angle between the earphone and the earphone box is θ 2, for example, 160 °.

In another possible implementation manner, the included angle between the earphone and the earphone box may refer to an included angle on a horizontal plane perpendicular to the ground plane.

In yet another possible implementation manner, the included angle between the earphone and the earphone box may also refer to an included angle in a three-dimensional space, that is, the included angle includes an included angle on a horizontal plane parallel to the ground plane and an included angle on a horizontal plane perpendicular to the ground plane.

In the present application, only the included angle on the horizontal plane parallel to the ground plane is taken as an example for explanation, and the present application does not limit the included angle.

In a possible implementation manner, if the earphones (which refer to two earphone components in a pair of earphones) are respectively worn on two ears of the user, for example, after the earphones detect that wearing is successful, an included angle between any one earphone component in the pair of earphones and the earphone box may be used as an included angle between the earphones and the earphone box.

Optionally, in this application, the distance between the earphone and the earphone box may be further calculated based on the intensity of the received bluetooth signal, and the relative position between the earphone and the earphone box may be determined by combining the acquired included angle between the earphone and the earphone box.

Optionally, in this application, the headset may further locate a current position of the headset based on a received Global Positioning System (GPS) signal, which may also be referred to as an absolute position, and perform accurate positioning based on the received GPS signal, a distance and an included angle between the headset and the headset case. The details will be described in the following examples.

In a possible implementation manner, the earphone in the present application may include one antenna, the earphone box may include two or more antennas, each antenna in the earphone box may be used to send out a bluetooth signal, and the bluetooth signal is in the form of a plane wave in the air, so that there is a time difference between the bluetooth signals sent out by different antennas in the earphone box and the antennas in the earphone. The earphone can obtain an included Angle between the earphone antenna and the earphone box antenna based on an Angle of Departure (AOD) calculation mode, wherein the included Angle between the earphone box antenna and each antenna in the earphone is equal.

In another possible implementation manner, the earphone may include two or more antennas, the earphone box may include one antenna, the antenna in the earphone box sends out a bluetooth signal, the signal is in the form of a plane wave in the air, and there is a time difference between the bluetooth signal sent out by the antenna in the earphone box and any two antennas in the earphone. The earphone can obtain an included angle between an earphone antenna and an earphone box antenna based on an angle of Arrival (AOA) calculation mode, wherein the included angle between each antenna in the earphone and the earphone box antenna is equal.

In another possible implementation manner, the earphone and the earphone box may include a plurality of antennas, and the earphone may adopt an AOA calculation manner or an AOD calculation manner to obtain an included angle between any antenna in the earphone and any antenna in the earphone box, that is, an included angle between the earphone and the earphone box.

It should be noted that, in the present application, if a plurality of antennas exist in an earphone box or an earphone, distances between any two antennas between the plurality of antennas may be the same or different, and the present application is not limited.

It should be further noted that, in the present application, an included angle obtained by the earphone antenna is equal to an included angle between the earphone and the earphone box.

It should be further noted that, in the present application, only the calculation manner of AOA and AOD is used for illustration, in other embodiments, other calculation manners may also be used to calculate an included angle between the earphone and the earphone box, for example, a Time of Arrival (TOA), which is not limited in the present application.

Referring to fig. 3b, taking two antennas, antenna 1 and antenna 2, as an example, in the headset, specifically, there may be a time difference △ t between the time points of receiving the bluetooth signal between antenna 1 and antenna 2, it can be understood that antenna 2 receives the bluetooth signal after antenna 1 receives the bluetooth signal and is separated by △ t.

Wherein, theta is the included angle between the earphone box and the earphone. d is the distance between the antenna 1 and the antenna 2, and c is the propagation speed of the Bluetooth signal in the air.

(II) AOD calculation mode

Referring to fig. 4a, the earphone includes one antenna, and the earphone case includes a plurality of antennas, as shown in fig. 4a, which illustrates a specific process of using the AOD calculation method. The number of antennas in each device in the drawing is only a schematic example, and the application is not limited. Each antenna in the earphone box sends bluetooth signal, and bluetooth signal transmits in the air, and for the earphone, bluetooth signal can regard as the plane wave after the air transmission.

Referring to fig. 4b, taking two antennas, antenna 1 and antenna 2, in the earphone box as an example, specifically, antenna 1 and antenna 2 transmit bluetooth signals, the antenna of the earphone receives the bluetooth signals transmitted by antenna 1 and receives the bluetooth signals transmitted by antenna 2 after △ t is separated, the earphone can calculate an included angle between the earphone and the earphone box based on formula (1).

Optionally, in this application, in order to reduce the device pressure of the headset, the headset may send parameters required for calculation to another terminal, such as a mobile phone, so as to calculate the included angle through the mobile phone. In an AOA-based calculation method, in one example, the headset may send the distance d between the antenna 1 and the antenna 2 in the headset and Δ t to the mobile phone, so that the mobile phone calculates an included angle between the headset and the headset box based on the formula (1) and the obtained parameters. In another example, in the AOD-based calculation mode, the headset may send Δ t to the mobile phone, where the mobile phone may further obtain the distance d between the antenna 1 and the antenna 2 in the headset box from the headset box side, and calculate the included angle between the headset and the headset box based on the formula (1) and the obtained parameters.

It should be noted that, in the present application, a bluetooth signal is taken as an example for description, in other embodiments, other wireless signals, for example, wifi signals and the like, may also be used as an information source for positioning the wearable device, and a specific implementation manner thereof is the same as that of the bluetooth signal, which is not described in detail herein.

The technical solutions of the above method embodiments are described in detail below using several specific examples.

Scene one

Referring to fig. 5, a schematic diagram of an application scenario including a computer, a television, an earphone box and a headphone is exemplarily shown. The earphone box can be placed at any position of the room where the computer and the television are located, and the technical scheme of the application is described in detail below with reference to fig. 5. With reference to fig. 5, as shown in fig. 6, a schematic flow chart of a positioning method of a wearable device in an embodiment of the present application is shown, in fig. 6:

step 101, connecting an earphone with a computer, and determining a first initial included angle between the earphone and an earphone box.

Specifically, in the present embodiment, as shown in fig. 7a, the user carries the headset, and the head (specifically, the face) of the user faces the computer (specifically, the computer screen), and controls the headset to connect to the computer. The connection mode of the earphone and the computer can refer to the prior art, and the application is not limited.

After the earphone is successfully connected with the computer, the Bluetooth signal sent by the earphone box can be received. Optionally, in this application, the earphone box may send the bluetooth signal after receiving the trigger signal sent by the earphone, or after receiving the trigger signal sent by other devices such as a mobile phone, so as to reduce power consumption of the earphone box. In one example, the trigger signal may be triggered by user control, e.g., a user may control a computer to cause the computer to send the trigger signal to an earphone box. In another example, after the earphone is successfully connected with the computer, the earphone box can be triggered to send the trigger signal.

Specifically, after the earphone receives the bluetooth signal sent by the earphone box, the included angle between the earphone and the earphone box can be calculated based on the AOA calculation mode, the AOD calculation mode or other calculation modes described above, and the specific calculation mode can refer to the above, which is not repeated herein. Referring to fig. 7a, in the present embodiment, an angle between the earphone and the earphone box of the right ear of the user is taken as an angle between the earphone and the earphone box, and illustratively, when the user faces the computer, the angle between the earphone and the earphone box is θ 1, and in the present embodiment, θ 1 is 30 °.

In this embodiment, after the earphone acquires θ 1, the included angle is determined as a first initial included angle when the earphone is connected to a computer, and a corresponding relationship between the connection event 1 and the included angle is recorded. Specifically, the connection event 1 means that the earphone is connected to the computer, and the corresponding included angle is θ 1(30 °). For example, when the headset records a connection event, the connection event may be marked by identification information of the computer, where the identification information may be IP address information of the computer or a device name of the computer, and the application is not limited in this application.

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

And 102, connecting the earphone with the television, and determining a second initial included angle between the earphone and the earphone box.

Specifically, in this embodiment, as shown in fig. 7b, the user carries the headset, and the head (specifically, the face) of the user faces the television (specifically, the television screen), and controls the headset to connect to the television. The connection mode of the earphone and the television can refer to the prior art, and the application is not limited.

After the earphone is successfully connected with the television, the Bluetooth signal sent by the earphone box can be received. The earphone can obtain an included angle θ 2 between the earphone and the earphone box based on the received bluetooth signal, and in this embodiment, θ 2 is 120 ° for example.

In this embodiment, after the earphone acquires θ 2, the included angle is determined as a second initial included angle when the earphone is connected to the television, and a corresponding relationship between the connection event 2 and the included angle is recorded. Specifically, the connection event 2 means that the earphone is connected to the television, and the corresponding included angle is θ 2(120 °). For example, when the headset records a connection event, the connection event may be marked by identification information of the television, where the identification information may be IP address information of the television or a device name of the television, and the application is not limited in this application.

And 103, acquiring an included angle between the earphone and the earphone box by the earphone, determining a corresponding connection event, and connecting the corresponding equipment.

Specifically, in this embodiment, the earphone can monitor the included angle between the earphone and the earphone box in real time. For example, if the earphone 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 television through the earphone to receive the audio of the television, the user may turn the head to the television screen, that is, as shown in fig. 7b, the earphone detects that the included angle between the earphone and the earphone box is 120 °, the earphone may be matched based on the association relationship between the included angle and the locally recorded connection event, and when the matched included angle is 120 °, the corresponding connection event is connection event 2, that is, the earphone is connected to the television. The earphone can be disconnected from the computer, can be connected with the television based on the stored connection parameters, and receives audio data sent by the television.

Similarly, if the user turns the head to the computer, after the earphone detects that the included angle between the earphone and the earphone box is 30 degrees, the earphone can be matched based on the associated relationship between the included angle and the connection event and the included angle recorded locally, and when the included angle is matched to be 30 degrees, the corresponding connection event is a connection event 1, that is, the earphone is connected with the computer. The earphone can be disconnected with the television, can be connected with the computer based on the stored connection parameters, and receives audio data sent by the computer.

In one possible implementation, an angle range may be provided in the earphone, which allows the angle between the earphone and the earphone box to be determined to meet a certain initial angle when the angle is within the range. The setting of the included angle range can be set according to actual parameters, and the method is not limited in the application. For example, in this embodiment, the included angle range may be set to 30 °, that is, when the included angle between the earphone and the earphone box is between 0 ° and 60 °, the included angle between the earphone and the earphone box may be considered to be consistent with the first initial included angle, that is, the earphone may be connected to the computer. When the included angle between the earphone and the earphone box is 90-150 degrees, the included angle between the earphone and the earphone box can be considered to accord with the second initial included angle, and the earphone can be connected with a television.

In one possible implementation, if the angle between the headset and the headset case exceeds a certain initial angle range, but does not yet satisfy other initial angle ranges, the headset may remain connected to the currently connected device until the next device is connected, in one example. For example, when the earphone is currently connected to the computer, the user obtains that the included angle between the earphone and the earphone box is 80 ° which exceeds the range of the first initial included angle (0 ° to 60 °), but does not satisfy the range of the second initial included angle (90 ° to 150 °), the earphone can be connected to the computer, and after the range of the second initial included angle is satisfied, the connection with the computer is disconnected, and the television is connected. In another example, if the included angle between the earphone and the earphone box does not satisfy any range of the initial included angle within the first preset time period, the earphone may be disconnected from the currently connected device. It should be noted that the purpose of setting the first preset time period is to avoid repeated connection between the earphone and the same device in a short time, for example, the first preset time period may be 1 minute, and the preset time period may be set according to actual needs, which is not limited in this application.

In another possible implementation manner, a second preset duration may be set in the earphone, and the preset duration is used for preventing 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 range of the first initial included angle within the second preset time period, the earphone is connected to the computer. It should be noted that the second preset time period may be set according to an actual requirement, for example, may be set to 3s, and the application is not limited in this application.

In yet another possible implementation manner, if the position of the earphone box is moved, the user may reset the corresponding relationship between the connection event and the included angle recorded in the earphone, that is, re-loop the

steps

101 and 102.

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

It should be noted that, in this scenario, only the connection between the earphone and the two devices is illustrated, and actually, the earphone may be connected to a plurality of devices, and the corresponding relationship between the connection event and the included angle is recorded, so that the automatic connection between the earphone and the devices is realized.

In a possible implementation manner, the technical scheme of the application can also be used for correcting the relative position of the positioning equipment in the space.

Referring to fig. 8, a schematic diagram of an application scenario including smart glasses and glasses cases is exemplarily shown. The glasses case can be placed at any position in a room where the intelligent glasses are located, and the technical scheme of the application is described in detail with reference to fig. 8.

Specifically, the user wears the intelligent glasses, and after the intelligent glasses detect that wearing is successful, the orientation of the intelligent glasses in the space can be acquired based on devices such as a compass arranged in the intelligent glasses, specifically, the spatial orientation towards which the user wears the intelligent glasses. However, due to the inaccuracy of the spatial orientation, for example, the smart glasses can only judge that the smart glasses are oriented to the east, south, west, north, southeast, northeast, southwest, and northwest, which are eight directions. For scenes in which the direction needs to be accurately positioned, for example, a user wears intelligent glasses to enjoy paintings in an art gallery, and the intelligent glasses can be positioned through the spatial direction to determine the content, introduction and the like of the corresponding paintings needing to be displayed. In this scenario, the spatial orientation where the smart glasses are located needs to be further corrected to accurately correct the orientation of the smart glasses in space.

For example, as shown in fig. 8, the smart glasses may obtain an included angle between the smart glasses and the glasses case, and the obtaining manner of the included angle may refer to the above, and is not described herein again. The smart glasses may determine the relative orientation of the smart glasses in space in conjunction with the acquired spatial orientation in which they are oriented. For example, the smart glasses acquire that the space direction in which the smart glasses are oriented is the northeast direction through the compass, and after the user sets the glasses case in the north-positive wind direction, based on the included angle between the glasses case and the smart glasses, the smart glasses may determine that the current relative direction in the space is 30 ° northeast. When the intelligent glasses are applied to scenes of art museums, the specific spatial directions of the paintings and the corresponding contents, introduction and other information can be preset by the intelligent glasses, and when the direction towards which the intelligent glasses are obtained is 30 degrees north-east, namely, when the user faces the paintings in the direction 30 degrees north-east, the contents and introduction of the paintings corresponding to the directions can be displayed.

In summary, in the present application, a user may locate wearable devices such as earphones and/or smart glasses by using a device that can be obtained at any time, for example, the earphone box and/or the glasses box, as a beacon source, so as to obtain the orientation of the wearable devices. Optionally, in the present 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.

Scene two

Referring to fig. 9, a schematic diagram of an application scenario is exemplarily shown, referring to fig. 9, in which a handset and a headset are included, wherein the handset and the headset are in different rooms. The following describes in detail a specific application of the technical solution of the present application in an object finding scene with reference to fig. 9. With reference to fig. 9, as shown in fig. 10, a schematic flowchart of a positioning method of a wearable device in an embodiment of the present application is shown, in fig. 10:

step 201, the mobile phone sends a bluetooth signal.

Step 202, the mobile phone detects whether accurate position information returned by the earphone is received.

Specifically, in this embodiment, the accurate position information refers to position information including a distance between the earphone and the mobile phone and an included angle between the earphone and the mobile phone, that is, the accurate position information includes distance information and direction information.

For example, in this embodiment, since the earphone and the mobile phone are located in different rooms, and because the earphone is shielded by an obstacle, the earphone cannot receive the bluetooth signal sent by the mobile phone, that is, the earphone cannot acquire the parameters required for calculating the included angle and the distance, so that accurate position information cannot be returned to the mobile phone, and the mobile phone does not detect the accurate position information returned by the earphone, and step 203 is executed.

Step 203, the mobile phone acquires the GPS location information of the headset.

The mode of acquiring the GPS location information of the headset by the mobile phone may refer to the prior art, and is not described in detail in this application.

Specifically, in this embodiment, after the mobile phone acquires the GPS location information of the headset, the location of the headset, specifically, the location located by the GPS, may be displayed on the screen. It should be noted that the GPS position fix indicates an approximate position, which has an error with the actual position of the headset, for example, the error may be 3 m.

For example, in this embodiment, the mobile phone may indicate the location of the headset to the user through the display screen after acquiring the GPS location information of the headset, as shown in fig. 11, for example, the mobile phone may store a schematic plan view of the residence of the user, and after acquiring the GPS location of the headset, display the room where the headset is located on the screen.

The user can hold the mobile phone to enter a room where the earphone is located.

And step 204, the earphone responds to the received Bluetooth signal sent by the mobile phone to acquire the accurate position information of the earphone.

For example, after the mobile phone and the headset are in the same room, the headset may receive a bluetooth signal sent by the mobile phone, and calculate accurate position information of the headset based on the received bluetooth signal, which may also be understood as relative position information between the headset and the headset, where the accurate position information includes a distance between the headset and the mobile phone and an included angle between the headset and the mobile phone.

Specifically, after the earphone receives the bluetooth signal, the distance between the earphone and the mobile phone can be calculated based on the signal intensity of the received bluetooth signal. The specific calculation method can refer to the prior art, and the application is not limited.

In this embodiment, the earphone may further calculate an included angle θ between the earphone and the mobile phone based on the received bluetooth signal, and the specific calculation manner is as described above and is not described herein again.

Illustratively, in the present application, the distance from the earphone to the mobile phone is 2m, and an included angle between the earphone and the mobile phone is 30 °.

In step 205, the mobile phone obtains accurate position information of the headset.

And step 206, displaying the accurate position information of the earphone by the mobile phone.

Specifically, in this embodiment, after the earphone acquires the distance and the included angle between the earphone and the mobile phone, the parameters may be sent to the mobile phone, that is, the accurate position information is sent to the mobile phone.

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

It should be noted that, in the present embodiment, the accurate position of the headset may also be understood as a relative position between the headset and the mobile phone. For example, as shown in fig. 12, the mobile phone may convert the acquired accurate position information of the headset into the display manner in fig. 12 based on a compass, and the display manner in fig. 12 is only an illustrative example, and the application is not limited thereto.

It should be further noted that in the present embodiment, two earphone components of a pair of earphones are taken together, and a relative position between one of the earphones and the mobile phone is taken as an example of a relative position between the pair of earphones and the mobile phone.
