[0048] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a Wi-Fi interface). The memory 1005 may be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory. The memory 1005 may optionally also be a storage device independent of the aforementioned processor 1001.

[0052] Those skilled in the art will understand that Figure 1The terminal device structure shown in the figure does not constitute a limitation on the terminal device, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0053] like Figure 1 As shown, the memory 1005 as a computer storage medium may include an operating system, a network communication module, a user interface module, and a control program for the wearable device.

[0054] exist Figure 1 In the terminal shown, the network interface 1004 is mainly used to connect to the background server and communicate data with the background server; the user interface 1003 is mainly used to connect to the client and communicate data with the client; and the processor 1001 can be used to call the control program of the wearable device stored in the memory 1005 to implement various embodiments of the control method of the wearable device of the present invention.

[0055] Based on the above-mentioned terminal device, various embodiments of the control method of the wearable device of the present invention are proposed. In various embodiments of the motion monitoring method of the wireless headset of the present invention, the control method of the wearable device of the present invention is applied to the process of monitoring the motion of the headset wearer based on the wireless headset.

[0056] Please refer to Figure 2 , Figure 2 This is a flow chart of a first embodiment of a control method for a wearable device according to the present invention. In the first embodiment of the control method for a wearable device according to the present invention, the control method for a wearable device according to the present invention is applied to a first wearable device in an environment where multiple wearable devices coexist. The control method for a wearable device according to the present invention includes:

[0057] Step S10: When a preset wake-up voice is recognized from the voice information collected from the environment, the sound source of the voice information is localized to obtain the sound source information of the voice information;

[0058] In this embodiment, in an environment where multiple wearable devices exist at the same time, each wearable device acts as the first wearable device to collect voice information in the current environment, and detects whether the preset wake-up voice is recognized in the collected voice information. When the wake-up voice is recognized in the voice information, the sound source positioning operation is immediately performed on the voice information to obtain the sound source information of the voice information in the current environment.

[0059] For example, Figure 4As shown in the schematic diagram of the application scenario, in this embodiment, it is assumed that there are four users A, B, C, and D in the room, all wearing smart wearable devices, and the smart wearable device worn by user A is specifically a TWS headset. Then, when user B needs to connect to the TWS headset worn by user A through the headset he is wearing to interact, user B sends a voice message of "connecting to user A". In this way, the TWS headset worn by user A acts as the first wearable device to collect voice information in the current indoor environment, and recognizes the wake-up voice of "user A" from the voice information sent by user B, confirms that the wake-up is successful, and immediately starts to synchronize the sound features of the voice information collected by the microphones of its left and right earphones to perform TDOA (a method of positioning using time difference) sound source recognition operation to obtain the sound source information of the voice information sent by user B.

[0060] In addition, in some feasible embodiments, before the above step S10, the control method of the wearable device of the present invention may further include:

[0061] Step A: Setting the preset wake-up voice based on the unique identifier of the first wearable device, wherein the unique identifier includes at least one of a Bluetooth name, a device name, and a custom name.

[0062] In this embodiment, during the startup process, the first wearable device can set its own unique identifier: Bluetooth name, device name and / or custom name as the wake-up voice for waking itself up to connect and interact with other wearable devices by interacting with the user through voice.

[0063] In addition, the first wearable device can also be set up by the user through the associated mobile phone App to confirm that the Bluetooth name, device name and / or custom name are set as the wake-up voice for waking itself up to connect and interact with other wearable devices.

[0064] It should be understood that based on the different design requirements of actual applications, in different feasible implementation methods, the wearable device's own Bluetooth name, device name and user-set custom name may of course be different. Based on this, the control method of the wearable device of the present invention is not limited to the specific content of the wearable device's own Bluetooth name, device name and / or custom name, as long as each name can serve as a unique identifier of the wearable device for the wearable device to determine whether it has been awakened.

[0065] Furthermore, in some feasible embodiments, the control method of the wearable device of the present invention further includes:

[0066] Step B: collecting the voice information in the environment and determining that the wake-up voice is recognized from the voice information when detecting that the unique identifier exists in the text information corresponding to the voice information.

[0067] In this embodiment, after the above-mentioned first wearable device collects voice information sent by the wearer of other wearable devices from the current environment, it immediately performs voice content recognition on the voice information to obtain text information corresponding to the voice information, and thereby detects whether there is text content in the text information that is the same as its own unique identifier: Bluetooth name, device name and / or custom name, and when the existence is detected, determines that the unique identifier exists in the text information corresponding to the voice information, and further determines that a wake-up voice for waking itself up to connect and interact with other devices is currently recognized from the voice information.

[0068] In addition, in some feasible embodiments, the first wearable device is configured with an array microphone, and the sound source information of the voice information obtained by performing a sound source localization operation on the collected voice information by the first wearable device includes: a sound source azimuth angle.

[0069] The step of “localizing the sound source of the voice information to obtain the sound source information of the voice information” in the above-mentioned step S10 may include:

[0070] Step S101: Acquiring the arrival time difference of the voice information through the array microphone;

[0071] In this embodiment, after the first wearable device determines that the wake-up voice has been recognized from the collected voice information, it immediately performs a TDOA sound source recognition operation to obtain the sound source information of the voice information. In other words, the first wearable device synchronizes the sound features of the collected voice information through its own array microphones, thereby determining the time difference between the voice information reaching any two microphones in the array microphones.

[0072] Step S102: performing calculation based on the arrival time difference to determine the sound source azimuth angle of the voice information.

[0073] In this embodiment, after determining the time difference between the voice information reaching any two microphones in the array microphone configured by itself, the above-mentioned first wearable device calculates the distance difference based on the speed of the voice information propagating in the air and the time difference, and then infers the sound source azimuth angle of the voice information in the current environment relative to the first wearable device.

[0074] In addition, as a feasible implementation method, the first wearable device can also perform a sound source localization operation on the collected voice information based on beamforming and high-resolution spectrum estimation to identify the sound source azimuth angle of the voice information.

[0075] Step S20: locating the broadcast signal source of each second wearable device in the environment to obtain the broadcast signal source information of each second wearable device;

[0076] In this embodiment, after the above-mentioned first wearable device performs a sound source positioning operation on the collected voice information to identify the sound source information of the voice information, it further performs a broadcast signal source positioning operation on all second wearable devices that broadcast Bluetooth signals in the current environment to identify the broadcast signal source information of each second wearable device.

[0077] For example, Figure 4 In the application scenario shown, it is assumed that there are four users A, B, C, and D in the room, all wearing smart wearable devices. The smart wearable device worn by user A is specifically a TWS headset, and each of the smart wearable devices broadcasts Bluetooth signals in the current indoor environment. In this way, when user B needs to connect and interact with the TWS headset worn by user A through the headset he wears, and user B sends a voice message of "connecting with user A", the TWS headset worn by user A acts as the first wearable device to collect voice information in the current indoor environment, and performs the sound source positioning operation of the voice information of "connecting with user A" to confirm the sound source azimuth angle of user B relative to himself in the current indoor environment.

[0078] In addition, at the same time or after the TWS headset worn by user A starts to perform the sound source positioning operation on the voice information "connected to user A", the three smart wearable devices worn by users B, C and D are all regarded as second wearable devices, and the broadcast signal source positioning operation is started for the Bluetooth signals broadcast by each second wearable device to obtain the broadcast signal source information of each second wearable device. That is, the TWS headset worn by user A is used as the first wearable device to scan the radio frequency information of the second wearable device b worn by user B, the second wearable device c worn by user C, and the second wearable device d worn by user D through the left and right earphones and calculate the angle of each radio frequency information. Then, the TWS headset summarizes the calculated angles into the main earphone for position averaging and calibration, and obtains the broadcast signal source information of the second wearable device b: L1_1, R1_1, the broadcast signal source information of the second wearable device c: L2_1, R2_1, and the broadcast signal source information of the second wearable device d: L3_1, R3_1.

[0079] In addition, in some feasible embodiments, the above-mentioned first wearable device is configured with an array antenna, and the first wearable device performs broadcast signal source positioning operations on each of the above-mentioned second wearable devices respectively, and the obtained broadcast signal source information of each second wearable device includes: broadcast signal azimuth angle.

[0080] The above-mentioned step S20: locating the broadcast signal source of each second wearable device in the environment to obtain the broadcast signal source information of each second wearable device may include:

[0081] Step S201: receiving a broadcast signal from each of the second wearable devices through the array antenna;

[0082] Step S202: Calculating the phase difference of each broadcast signal in sequence based on different array elements in the array antenna;

[0083] Step S203: calling a preset signal angle estimation algorithm to perform calculation based on each of the phase differences to determine the broadcast signal azimuth angle of each of the second wearable devices.

[0084] It should be noted that, in this embodiment, the preset signal angle estimation algorithm is an algorithm for calculating the azimuth angle between the signal transmission source and the device where the array antenna is located based on the phase difference and the signal wavelength. For example, the signal angle estimation algorithm may be specifically:

[0085]

[0086] Where θ is the azimuth angle, λ is the wavelength of the broadcast signal, △Φ is the phase difference, and d is the relative distance between two elements in the array antenna.

[0087] In this embodiment, if Figure 3 The principle of broadcast signal source positioning shown in the figure is that the first wearable device uses its own array antenna to scan the broadcast signals output by each of the above-mentioned second wearable devices in a radio frequency manner. Therefore, the first wearable device can use the array antenna to perform IQ sampling to determine the phase difference caused by the different distances between the broadcast signals of each second wearable device and any two elements in the array antenna. Finally, the first wearable device further calculates the azimuth angle of the broadcast signal of each of the above-mentioned second wearable devices using the above-mentioned signal angle estimation algorithm.

[0088] Step S30: If the sound source information matches the target signal source information in each of the broadcast signal source information, a communication link is created between the target wearable device corresponding to the target signal source, and interactive control with the target wearable device is performed through the communication link.

[0089] In this embodiment, after the above-mentioned first wearable device further performs a broadcast signal source positioning operation on each second wearable device to identify the broadcast signal source information of each second wearable device relative to itself, the first wearable device matches the sound source information corresponding to the above-mentioned voice information with each broadcast signal source information one by one. Therefore, when the sound source information matches a target signal source among each broadcast signal source information, the first wearable device immediately connects to the target wearable device corresponding to the target signal source among each second wearable device, and establishes a communication link with the target wearable device, thereby further performing interactive control with the target wearable device through the communication link.

[0090] In some feasible embodiments, the first wearable device includes a master device and a slave device. Based on this, after the step S20 of locating the broadcast signal source of each second wearable device in the environment to obtain the broadcast signal source information of each second wearable device, the control method of the wearable device of the present invention may further include:

[0091] Step C: Aggregating the broadcast signal source information of each of the master devices for calibration processing to obtain the final angle value of each of the second wearable devices, wherein the broadcast signal source information of each of the master devices and / or the slave devices is obtained by locating the broadcast signal source;

[0092] Step D: Detecting whether there is a target angle value that matches the sound source information among the final angle values;

[0093] Step E: If it exists, the broadcast signal source information corresponding to the target angle value is determined as the target signal source information that matches the sound source information.

[0094] In this embodiment, after the above-mentioned first wearable device performs a broadcast signal source positioning operation on each second wearable device through the master device and / or the slave device to identify the broadcast signal source information of each second wearable device relative to itself, the above-mentioned first wearable device further aggregates the broadcast signal source information of each second wearable device to the master device for calibration processing, thereby obtaining the final angle value of each second wearable device. Afterwards, the first wearable device matches the sound source information corresponding to the above-mentioned voice information with each final angle value one by one, so that when the sound source information matches a target angle value among each final angle value, it is confirmed that the broadcast signal source corresponding to the target angle value among each broadcast signal source is the target signal source that matches the sound source information.

[0095] For example, Figure 4In the application scenario shown, the main earphone of the TWS earphone worn by user A uses data fusion to aggregate the broadcast signal source information L1_1, R1_1 of the second wearable device b (worn by user B), the broadcast signal source information L2_1, R2_1 of the second wearable device c (worn by user C), and the broadcast signal source information L3_1, R3_1 of the second wearable device d (worn by user D) obtained by performing the process shown in the above steps S201 to S203 on its own main earphone and / or the slave earphone to the main earphone for angle calibration calculation to obtain the final angle values ​​between the TWS earphone of user A and the second wearable device b, the second wearable device c, and the second wearable device d: T1, T2, and T3. Then, the TWS headset worn by user A will compare the sound source azimuth angle of user B relative to himself in the current indoor environment, who has performed the sound source positioning operation for the above voice information, with T1, T2 and T3 respectively, so as to detect the target angle value T1 among T1, T2 and T3 that matches the sound source azimuth angle. Then, the TWS headset worn by user A determines that the broadcast signal source information of the second wearable device b corresponding to the target angle value T1 in the above-mentioned broadcast signal source information is the target signal source that matches the sound source azimuth angle.

[0096] Furthermore, in some feasible embodiments, the step of "creating a communication link between the target wearable device corresponding to the target signal source and performing interactive control with the target wearable device through the communication link" in the above step S30 may include:

[0097] Step S301: establishing a Bluetooth connection between the target wearable device corresponding to the target signal source in each of the second wearable devices;

[0098] Step S302: establishing a communication link with the target wearable device via the Bluetooth connection;

[0099] Step S303: Outputting a preset voice prompt via the communication link to perform interactive control with the target wearable device.

[0100] In this embodiment, when the above-mentioned first wearable device determines that the above-mentioned sound source information matches the target signal source among the various broadcast signal source information, it immediately establishes a Bluetooth connection with the target wearable device corresponding to the target signal source among the various second wearable devices. Thereafter, based on the Bluetooth connection, it further creates a Bluetooth communication link between itself and the target wearable device, thereby further outputting voice prompts for itself and the respective wearers of the target wearable device through the communication link, so that the wearer can perform interactive control based on the function list supported by both itself and the target wearable device.

[0101] For example, Figure 5 In the application scenario shown, after the TWS headset worn by user A determines that the second wearable device b worn by user B is the target wearable device, it analyzes the service type supported by the second wearable device b through its own main headset to establish a Bluetooth connection with the second wearable device b. After that, the TWS headset further creates an LE Audio link with the second wearable device based on the Bluetooth connection (a lower power communication link in Bluetooth 5.2 technology, using the new LC3 encoding, capable of transmitting multiple stream audio and supporting broadcast functions). Furthermore, the TWS headset worn by user A can play the supported function list (such as synchronized equalizer parameters, etc.) with the second wearable device b worn by user B through the LE audio link, and user A can directly perform corresponding functional interactions according to the voice prompts output by the TWS headset through voice broadcast. Among them, the second wearable device b worn by user B transmits the voice prompts including the function information of the second wearable device b to the TWS headset through the LE audio link, and the TWS headset outputs it to user A through voice broadcast. Similarly, user B can also perform corresponding functional interactions according to the voice prompts output by the second wearable device b through voice broadcast.

[0102] Thus, in this embodiment, in an environment with multiple wearable devices, each wearable device acts as a first wearable device to collect voice information in the current environment and detect whether a preset wake-up voice is recognized in the collected voice information. Upon recognizing the wake-up voice in the voice information, the first wearable device immediately performs a sound source localization operation on the voice information to obtain the sound source information of the voice information in the current environment. The first wearable device then further performs a broadcast signal source localization operation on all second wearable devices in the current environment that are broadcasting Bluetooth signals to identify the broadcast signal source information of each second wearable device. Finally, the first wearable device matches the sound source information corresponding to the voice information with each broadcast signal source information one by one. When the sound source information matches a target signal source in each broadcast signal source information, the first wearable device immediately connects to the target wearable device corresponding to the target signal source among the second wearable devices and establishes a communication link with the target wearable device, thereby further performing interactive control with the target wearable device via the communication link.

[0103] Compared to traditional methods where users add and control wearable devices via remote controls or mobile phone apps, this invention uses voice to wake up the first wearable device to trigger connection preparation. It then performs sound source localization to locate the user who issued the voice call, locates the broadcast signal source to search for the locations of other second wearable devices, directly connects to the target wearable device with a matching location, and establishes a communication link for interactive control between the two devices. This allows users to quickly and flexibly connect and interactively control different wearable devices using voice, greatly simplifying user operations and effectively improving the efficiency and experience of user interaction with wearable devices.

[0104] In addition, an embodiment of the present invention further provides a control device for a wearable device, and the control device for a wearable device of the present invention is applied to a first wearable device.
