[0020] Detailed Implementation

[0021] This application aims to provide a Bluetooth communication method and an implementation of a wearable / mobile electronic device (which can be worn or used by a user), capable of simultaneously supporting audio / voice playback mode and walkie-talkie mode. The wearable / mobile electronic device can automatically switch from the audio / voice playback mode to the walkie-talkie mode and back again, enabling it to intelligently provide multiple operations and functions of both the audio / voice playback mode and the walkie-talkie mode to multiple users in different situations.

[0022] Please refer to the matching instructions. Figure 1 and Figure 2 . Figure 1 This is a simplified block diagram of a wearable / mobile electronic device 100 and a mobile phone device 110 according to an embodiment of this application. Figure 2 This is a schematic diagram illustrating the mode switching operation when the wearable electronic device 100 is used to implement two earphone devices, for example, one earphone device 100R for the user's right ear and one earphone device 100L for the user's left ear, according to an embodiment of this application. Each earphone device 100R and 100L includes the same circuit elements as the wearable electronic device 100, and these earphone devices can support the function and operation of true wireless stereo.

[0023] exist Figure 1The wearable / mobile electronic device 100 is, for example, an earphone / earbud device used as a user's left / right ear (but not limited) and simultaneously having Bluetooth communication capabilities, capable of communicating with a mobile phone device 110. The earphone device 100 successfully pairs with the mobile phone device 110 via Bluetooth communication. The earphone device 100 includes a processing circuit 101, such as a microcontroller (MCU), a communication circuit 102 supporting Bluetooth communication capabilities, a memory 103 (used to store or record unique information in the database INFO1 used in the walkie-talkie mode), a voice output unit 104 (e.g., a speaker), and a voice input unit 105 (e.g., a microphone unit). For example, the information database INFO1 recorded by the wearable electronic device 100 may contain one or more Medium Access Control (MAC) addresses, device identification (ID), name information (which may include multiple device names and / or multiple user names), and / or other unique information of one or more other different wearable electronic devices belonging to the same walkie-talkie group in which the wearable electronic device 100 also belongs. These other different wearable electronic devices may or may not be paired with the mobile phone device 110. The information of multiple device names and / or multiple user names recorded in the information database INFO1 can be used to indicate multiple different walkie-talkie groups and the name information of multiple members in each walkie-talkie group, enabling a user operating and using the wearable electronic device 100 to know who can hear their voice or speech. Several operations related to the information database INFO1 are described in later paragraphs.

[0024] The mobile device 110 includes a communication unit 115, a processing unit 120, and an interface unit 125. The communication unit 115 is used to relay or transmit multiple signals via multiple Bluetooth communications to communicate with the wearable electronic devices 100L and 100R respectively. The processing unit 120 is used to control the communication unit 115. The processing unit 120 is, for example, a digital processor or a central processing unit (CPU) implemented using multiple hardware components, multiple firmware components, multiple software components, or a combination of multiple hardware, firmware, and software components. The communication unit 115 may include a portion of multiple communication circuits that support the Bluetooth communication standard, the IEEE 802.11 family of standards, and / or wired broadband or mobile communication standards. In practice, the communication unit 115 may be a single integrated circuit supporting the Bluetooth communication standard, the IEEE 802.11 family of standards, and / or wired broadband or mobile communication standards. Alternatively, the communication unit 115 may also include multiple integrated circuits supporting multiple different communication standards; this is not a limitation of this application. Furthermore, the interface unit 125 is a user interface that can be operated by a user to launch or execute one or more mobile / software applications running on and executed by the processing unit 120.

[0025] The headset device 100 includes an audio playback mode and a walkie-talkie mode. The processing circuit 101 can determine the distance between the headset device 100 itself and at least one wearable electronic device, wherein the at least one wearable electronic device is, for example, one or more different headset devices that have also been successfully paired with the mobile phone device 110. The headset device 100 can determine whether the determined distance is greater than a specific distance threshold TH to determine whether to switch between the audio playback mode and the walkie-talkie mode. For example, in... Figure 2 The earphone device 100R can detect the signal power of a Bluetooth signal sent from another earphone device 100L to determine whether the distance between the two earphone devices 100R and 100L is greater than a specific distance threshold TH.

[0026] In practice, the processing circuit 101 can control the communication circuit 102 to detect, in real time or periodically, the signal power (e.g., RF power level) of the Bluetooth radio frequency signal transmitted from at least one other headset device (e.g., a headset device paired with the mobile phone device 110), and then calculate or estimate the distance between the headset devices based on the detected signal power magnitude. Alternatively, in other embodiments, the processing circuit 101 can also use a Bluetooth direction finding operation to detect the angle of arrival / angle of departure of the Bluetooth signal transmitted from one or more different headset devices paired with the mobile phone device 110 to determine or calculate the distance. Furthermore, in other embodiments, the processing circuit 101 can also use connection signal information carried by the Bluetooth signal transmitted from the one or more different headset devices to determine or calculate the distance.

[0027] Furthermore, the specific distance threshold TH is, for example, equal to three meters (but not limited to). In one embodiment, the specific distance threshold TH can be different values ​​and can be determined by multiple different users.

[0028] The processing circuit 101 compares the determined / calculated distance with a specific distance threshold TH to determine whether to switch modes. If the distance is less than the specific distance threshold TH, the processing circuit 101 determines whether the headphone device 100 and one or more headphone devices are being used by the same user / person to listen to music or by multiple different users / persons nearby to share and listen to music. Based on this, the processing circuit 101 determines whether the headphone device 100 is in the audio playback mode or remains in the audio playback mode. Please refer again. Figure 2 ,exist Figure 2 In the embodiment on the left, if the calculated distance is less than the specific distance threshold TH, the headphone devices 100R and 100L (both implemented by the wearable electronic device 100) will decide to maintain the audio playback mode. In this mode, the mobile phone device 110 will send one or more mono or stereo audio packet streams to the headphone devices 100L and 100R, and the communication circuits 102 in the headphone devices 100L and 100R can respectively receive the one or more audio packet streams sent by the mobile phone device 110. In another embodiment, if a headphone device, such as headphone device 100L (but not limited to), acts as a slave device, then the headphone device can receive an audio packet stream sent from the mobile phone device 110 and relayed by headphone device 100R (as the master device). Figure 2In the embodiment on the left, the processing circuits 101 in the headphone devices 100L and 100R are able to control the corresponding multiple voice output units 104 (i.e. multiple speakers) to play audio / sound / music in the left and right channels respectively to the same user UA based on one or more received audio packet streams sent from the corresponding multiple communication circuits 1024.

[0029] When the distance exceeds a specific distance threshold TH, the processing circuit 101 determines that the wearable electronic device 100 and one or more other electronic devices are being used by different users / people and that these different users / people are not close together. Based on this, it decides to control the wearable electronic device 100 to enter the walkie-talkie mode to initiate a walkie-talkie conversation between one or more people. For example, in... Figure 2 In the embodiment on the right, when the distance between the two earpiece devices 100R and 100L is greater than the specific distance threshold TH, the processing circuits 101 of the wearable electronic devices 100 (which respectively implement the two earpiece devices 100R and 100L) will decide to enter the walkie-talkie mode. In this case, the processing circuits 101 in the two earpiece devices 100R and 100L will determine that the two earpiece devices 100R and 100L are worn by different users (UA and UB), and accordingly control the earpiece devices 100R and 100L respectively. L enters the walkie-talkie mode to conduct multiple group voice communications between the different users UA and UB. The processing circuits 101 can automatically and / or simultaneously control the headsets 100R and 100L to enter the walkie-talkie mode once the distance becomes greater than the specific distance threshold TH. Once the distance becomes less than the specific distance threshold TH, the processing circuits 101 can automatically and / or simultaneously control the headsets 100R and 100L to switch back from the walkie-talkie mode to the audio playback mode.

[0030] Furthermore, in one embodiment, when the detected distance exceeds the specific distance threshold TH, the group voice communication in the walkie-talkie mode can also be triggered by an earpiece device, and subsequently allowed or accepted by one or more other earpiece devices to establish the group voice communication. For example, in Figure 2In this context, the headset devices 100R and 100L can also agree with each other to decide whether to enter the walkie-talkie mode, instead of automatically switching to it directly. For example, when the detected distance is greater than the distance threshold TH, the processing circuit 101 of one headset device (e.g., 100R) can control the voice output unit 104 to play a voice message to the user UA to check whether the user UA wants to enter the walkie-talkie mode. For example, the user UA can issue a voice control command, tap, or click the headset device 100R to indicate approval or rejection of the played voice message. For example, the voice input unit 105 can be used to receive the voice control command. If the user UA approves the walkie-talkie mode, the processing circuit 101 in the headset device 100R will control the communication circuit 102 to generate a request signal (the request signal is used to request to enter the walkie-talkie mode). If the headset devices are also paired, the request signal will be sent from the headset device 100R to the headset device 100L via direct Bluetooth communication. Or, if the headset devices are not paired, the request signal will be sent from the headset device 100R to the headset device 100L via the mobile phone device 110.

[0031] When the request signal from the headset 100R is received, the processing circuit 101 in the headset 100L controls the corresponding voice output unit 104 to play a voice message of the request signal to the user UB. This allows the user UB to accept or reject the request by issuing a voice control command or tapping or pressing the headset 100L. If the request signal is accepted by the user UB, the processing circuit 101 in the headset 100L controls the corresponding communication circuit 102 to generate a response signal. If the headsets are paired, the response signal is sent from the headset 100L to the headset 100R via direct Bluetooth communication. If the headsets are not paired, the response signal is sent from the headset 100L to the headset 100R via the mobile phone device 110. If the response signal indicates that the user UB accepts the walkie-talkie mode, then the headset devices 100R and 100L can enter the walkie-talkie mode, enabling the user UA and UB to use the headset devices 100R and 100L respectively for group voice communication. The voice data (e.g., one or more voice packets) of the group voice communication can be relayed through the mobile phone device 110, or it can be transmitted directly between the headset devices 100R and 100L. For example, if the direct transmission of voice data between the two wearable electronic devices (i.e., headset devices 100R and 100L) fails, the voice data of the walkie-talkie conversation can also be transmitted through the mobile phone device instead.

[0032] In other words, when a headset device implemented by the wearable electronic device 100 detects that the distance between the headset device and one or more other headset devices is greater than the specific distance threshold, the headset device can automatically enter the walkie-talkie mode or play a voice assistance message to a user, allowing the user to choose whether to enter the walkie-talkie mode. Thus, even when the distance between the headset devices 100R and 100L is large, the headset devices 100R and 100L implemented by the wearable electronic device 100 can still provide the user UA and UB with the flexible choice to stay in the audio playback mode without entering the walkie-talkie mode.

[0033] When the headset devices 100R and 100L are both in the walkie-talkie mode, the processing circuit 101 in each headset device 100R and 100L can control the corresponding communication circuit to generate and transmit a voice packet signal in response to the voice or sound of the user UA / UB. The voice or sound can be sensed, received and encapsulated by multiple corresponding voice input units 105 to generate multiple voice packet signals. For the mobile device 110, the processing unit 120 controls the communication unit 115 to forward and relay the voice packet signal sent from the headset device, for example 100R, to the headset device, for example 100L. When the voice packet signal relayed from the mobile device 110 is received, the processing circuits 101 in each headset device 100R and 100L can control multiple corresponding voice output units 104 to play the voice or sound of the user to the current user. In practice, the voice packet signal can be played using the telephone mode of the mobile device 110 to automatically and directly interrupt one or more operations currently being performed by the headset device, for example 100L. That is, when the headset device 100L is in walkie-talkie mode, the operation on the headset device 100L can be automatically interrupted and replaced by playing the voice packet signal from the headset device 100R.

[0034] It should be noted that, in Group information In an embodiment, when the user UA operates the headset devices 100R and 100L in audio playback mode (i.e., the distance between the two headset devices is less than a specific distance threshold TH, specifically less than a minimum threshold less than TH), the headset devices 100R and 100L can be classified by the user UA into the same voice communication group. Therefore, the headset devices 100R and 100L will exchange and share their Media Access Control Addresses (MAC addresses), the MAC address of the mobile device 110, and other unique information. For example, the information in the database INFO1 recorded in each of the headset devices 100R and 100L can be represented by the following table:

[0035] Address of member device Address of mobile phone Name information ADDR L A ADDR 110 N L ADDR R ADDR 110 N R Figure 3

[0036] In the table above, the walkie-talkie group 'A', for example, includes two member devices (e.g., two headset devices 100L and 100R) with MAC addresses ADDR_L and ADDR_R, the mobile phone device 110 with MAC address ADDR_110 (the same MAC address), and different name information (e.g., N_L and N_R representing the left and right ears respectively). It should be noted that the information database INFO1 may not be used; that is, the information database INFO1 may be optional in the above embodiments. However, this is not a limitation of this application.

[0037] In another embodiment, more than two headsets paired with a single mobile device can also be used by more than two different users / people to conduct voice communication in a voice group in the walkie-talkie mode, or to realize different group calls or conversations in different voice groups. Figure 1 This is an example schematic diagram of multiple earphone devices paired with a single mobile phone device according to an embodiment of this application. Each of these earphone devices 100_1, 100_2, 100_3, 100_4, and 100_5 is used by users U1, U2, U3, U4, and U5 respectively, and is powered by... Figure 3 The wearable electronic device 100 is implemented in the above, and the operation and circuit elements of the wearable electronic device 100 are the same as those of the headphone devices 100_1, 100_2, 100_3, 100_4 and 100_5.

[0038] like Group informationAs shown, within the signal transmission / reception range of the mobile device 110, for example, when each of the headset devices 100_1, 100_3, and 100_5 is paired with the mobile device 110 before entering the walkie-talkie mode, users U1, U3, and U5 wearing the headset devices 100_1, 100_3, and 100_5 can agree to manually operate the mobile device 110 through at least one user to use and manipulate the user interface 125 to classify their headset devices 100_1, 100_3, and 100_5 into the same voice communication group (e.g., classified as a first voice group). When the headset devices 100_1, 100_3, and 100_5 are classified into the same voice communication group, such as the first voice group, the mobile device 110 will send unique information of multiple other different headset devices in the first voice group to each headset device (i.e., each member) in the first voice group. For example, the processing unit 120 may, in practice, classify the MAC addresses of the headset devices 100_1, 100_3, and 100_5 into a first walkie-talkie group, transmit the MAC addresses of the headset devices 100_1 and 100_3 to the headset device 100_5, transmit the MAC addresses of the headset devices 100_1 and 100_5 to the headset device 100_3, and transmit the MAC addresses of the headset devices 100_3 and 100_5 to the headset device 100_1, such that the information database INFO1 recorded in the headset device 100_5 contains the MAC addresses of the headset devices 100_1 and 100_3, the information database INFO1 recorded in the headset device 100_3 contains the MAC addresses of the headset devices 100_1 and 100_5, and similarly, the information database INFO1 recorded in the headset device 100_1 contains the MAC addresses of the headset devices 100_3 and 100_5.

[0039] In detail, the database INFO1 in each of these headphone devices 100_1, 100_3, and 100_5 can be represented, for example, by the following table:

[0040] Address of member device Address of mobile phone Name information ADDR 1 A1 ADDR 110 ADDR 3 N_1 ADDR 110 ADDR 5 N_3 ADDR 110 Group information N_5

[0041] In the table above, the walkie-talkie group 'A1' for example includes three member devices (e.g., headset devices 100_1, 100_3, and 100_5) with MAC addresses ADDR_1, ADDR_3, and ADDR_5, and the same MAC address ADDR_110 for the mobile phone device 110, as well as different name information, such as N_1, N_3, and N_5 representing different users U1, U3, and U5 respectively.

[0042] Similarly, for a second voice group different from the first voice group, users U2 and U4 wearing the headset devices 100_2 and 100_4 respectively can also agree to manually operate the mobile phone device 110 to use and operate the user interface to classify their headset devices 100_2 and 100_4 into the same voice communication group, such as the second voice group, before entering the walkie-talkie mode and when each of the headset devices 100_2 and 100_4 is paired with the mobile phone device 110. When headset devices 100_2 and 100_4 are classified into the same voice communication group, such as the second voice group, the mobile phone device 110 sends unique information of one or more other different headset devices in the second voice group to each headset device (i.e., each member device) in the second voice group. For example, the processing unit 120 actually classifies the MAC addresses of headset devices 100_2 and 100_4 into a second walkie-talkie group, transmits the MAC address of headset device 100_2 to headset device 100_4, and transmits the MAC address of headset device 100_4 to headset device 100_4. 100_2, such that the information database INFO1 recorded in the headset device 100_2 contains the MAC address of the headset device 100_4, and the information database INFO1 recorded in the headset device 100_4 contains the MAC address of the headset device 100_2, so that even if other electronic devices are also within the signal transmission / reception range of the mobile phone device 110 and are also paired with the mobile phone device 110 via Bluetooth communication, as long as these other electronic devices do not belong to the same voice group, the aforementioned information database INFO1 will not contain the MAC addresses of these other electronic devices.

[0043] For example, the database INFO1 in each of these headphone devices 100_2 and 100_4 can be represented by the following table:

[0044] Address of member device Address of mobile phone Name information ADDR 2 A2 ADDR 110 ADDR 4 N_2 ADDR 110 Figure 3 N_4

[0045] In the table above, the walkie-talkie group 'A2' includes, for example, two devices with MAC addresses ADDR_2 and ADDR_4 (e.g., headset devices 100_2 and 100_4), the same MAC address ADDR_110 for mobile phone device 110, and different name information, such as the names N_2 and N_4 representing different users U2 and U4, respectively.

[0046] For example, when headsets 100_1, 100_3, and 100_5 are in walkie-talkie mode, a voice packet signal sent from headset 100_1 carries the MAC address ADDR_1 of headset 100_1. Headset 100_3, for instance, can receive this voice packet signal, and then the processing circuit 120 in headset 100_3 can compare the MAC address ADDR_1 in the voice packet signal with the recorded information database INFO1 to determine whether to play the voice / sound of the voice packet signal to user U3. Since the MAC address ADDR_1 can be found in the recorded information database INFO1 of headset 100_3, headset 100_3 can play the voice or sound of the voice packet signal to user U3. The operation of headset 100_5 is similar and will not be repeated here. Since the MAC address ADDR_1 cannot be found in the information database INFO1 of the headset devices 100_2 and 100_4, after comparing the multiple MAC addresses carried in the voice packet signals with the recorded information database INFO1, the headset devices 100_2 and 100_4 will decide to discard the voice packet signals generated by the headset devices 100_1, 100_3 and 100_5 and will not play the corresponding voice or sound to the users U2 and U4. Therefore, through the above method, dialogue between different voice groups can be realized in the walkie-talkie mode.

[0047] Furthermore, in some embodiments, if Group information The headset device 100_1 is classified into the second voice group mentioned above. The information database INFO1 for the headset device 100_1 can then be represented by the following table:

[0048] Address of member device Address of mobile device Name information ADDR 1 A1 ADDR 110 ADDR 3 N_1 ADDR 110 ADDR 5 N_3 ADDR 110 ADDR 1 N_5 A2 ADDR 110 ADDR 2 N_1 ADDR 110 ADDR 4 N_2 ADDR 110 Figure 4 N_4

[0049] Furthermore, in one embodiment, the walkie-talkie mode can support the transmission of multiple voice packet signals from multiple different mobile devices via the Bluetooth communication standard. Figure 4 This is an example diagram illustrating how multiple users / people in the same voice group communicate with each other by using two mobile devices to forward or relay multiple voice packet signals in walkie-talkie mode, according to an embodiment of this application. Each of these headset devices 100A_1, 100A_2, 100B_1, 100B_2, and 100B_3 includes the same circuit elements (not shown) of the wearable electronic device 100. Figure 4 (Simplified illustration) Each mobile device 110A and 110B includes the same circuit elements as mobile device 110 (not shown). Figure 4(Simplified illustration) Each headset device 100A_1, 100A_2, 100B_1, 100B_2 and 100B_3 can detect whether the distance between itself and any of the headset devices is greater than a specific distance threshold in order to determine whether to enter the walkie-talkie mode.

[0050] like Group information As shown, the group settings for the walkie-talkie mode can be configured before the wearable electronic devices 100A_1, 100A_2, 100B_1, 100B_2, and 100B_3 (i.e., the headset devices) enter the walkie-talkie mode. For example, the devices of users UA1, UA2, UB1, UB2, and UB3 can be classified into the same voice group. In practice, at least one of these users can be used to activate the single-processor running on the mobile devices 110A and 110B. A specific application software executed by Yuan 120 exchanges and shares the MAC addresses of the headset devices, the MAC addresses of the mobile devices, and / or other corresponding information (such as the name information of the corresponding headset devices 100A_1, 100A_2, 100B_1, 100B_2, and 100B_3). The information database INFO1 recorded in each of the headset devices 100A_1, 100A_2, 100B_1, 100B_2, and 100B_3 can be represented in the following table:

[0051]

[0052]

[0053] In this table, the walkie-talkie group 'A3', for example, includes five member devices (e.g., headset devices 100A_1, 100A_2, 100B_1, 100B_2, and 100B_3) with MAC addresses ADDR_UA1, ADDR_UA2, ADDR_UB1, ADDR_UB2, and ADDR_UB3, two mobile phone devices 110A and 110B with two different MAC addresses ADDR_110A and ADDR_110B, and different name information (e.g., N_UA1, N_UA2, N_UB1, N_UB2, and N_UB3).

[0054] For example, when the headset devices 100A_1, 100A_2, 100B_1, 100B_2, and 100B_3 are in the walkie-talkie mode, a voice packet signal sent from the headset device 100A_1 will carry walkie-talkie group information such as "A3", the MAC address of the headset device 100A_1 ADDR_UA1, and / or the destination address of one or more mobile devices, wherein the information includes, for example, the MAC addresses of mobile devices 110A and 110B ADDR_110A and ADDR_110B.

[0055] When the voice packet signal is received from headset device 100A_1, the processing unit 120 in mobile device 110A controls its communication unit 115 to broadcast the voice packet signal to multiple headset devices within its signal range and re-encode the voice packet signal to relay and forward the voice packet signal from mobile device 110A to mobile device 110B via Bluetooth communication based on the destination address information of one or more mobile devices (i.e., ADDR_110A and ADDR_110B). Then, after receiving the voice packet signal from mobile device 110A, mobile device 110B broadcasts the voice packet signal to headset devices within its signal range. In this case, headset device 100A_2 can receive the voice packet signal and play one or more voice messages related to user UA1 to user UA2, allowing user UA2 to be aware of the voice communication of walkie-talkie group "A3" in walkie-talkie mode. In addition, the headset devices 100B_1, 100B_2 and 100B_3 can also receive the voice packet signal and play one or more voice messages related to user UA1 to users UB1, UB2 and UB3 respectively.

[0056] In another embodiment, for example, the devices of users UA1 and UB2 can be further classified into another voice group. The information database INFO1 recorded in the headset device 100A_1 can be represented by the following table:

[0057] Address of member device Address of mobile device Name information ADDR UA1 A3 ADDR 110A N UA1 ADDR UA2 ADDR 110A N UA2 ADDR UB1 ADDR 110B N UB1 ADDR UB2 ADDR 110B N UB2 ADDR UB3 ADDR 110B N UB3 ADDR UA1 A4 ADDR 110A N UA1 ADDR UB2 ADDR 110B N UB2 Figure 5

[0058] In the table above, in addition to the walkie-talkie group 'A3', there is also a walkie-talkie group 'A4'. For example, walkie-talkie group 'A4' includes two member devices (e.g., headset devices 100A_1 and 100B_2) with MAC addresses ADDR_UA1 and ADDR_UB2, two mobile phone devices 110A and 110B with different MAC addresses ADDR_110A and ADDR_110B, and different name information such as N_UA1 and N_UB2. When the voice packet signal of walkie-talkie group 'A4' sent from the headset device 100A_1 is received, the mobile phone device 110A will not broadcast the voice packet signal to other headset devices within its signal range. Instead, based on the destination address information of one or more mobile phone devices received, i.e., ADDR_110B, it will relay and forward the voice packet signal from mobile phone device 110A to mobile phone device 110B via Bluetooth communication. Then, after receiving the voice packet signal from mobile phone device 110A, the mobile phone device... 110B will broadcast the voice packet signal to the headset devices within its signal range. In this case, headset device 100B_2 can receive the voice packet signal and play one or more voice messages about user UA1 to user UB2, so that user UB2 can know about the voice communication of the walkie-talkie group "A4" in the walkie-talkie mode. However, since other headset devices 100B_1 and 100B_3 are not in the walkie-talkie group "A4", these headset devices 100B_1 and 100B_3 will not receive the voice packet signal.

[0059] In another embodiment, one or more voice packet signals in walkie-talkie mode can be relayed or relayed by one or more mobile devices in a multi-hop network via one or more Bluetooth communication connections. Figure 5 This is an example illustration illustrating how multiple users / persons belonging to the same group can communicate with each other in walkie-talkie mode by using more than two mobile devices to forward or relay multiple voice packet signals in the same mode, according to an embodiment of this application. Figure 4As shown, the mobile devices 100A, 100B, 100C, and 100D are located in a Bluetooth multi-hop network. Each of the headset devices 100A_1, 100A_2, 100B_1, 100B_2, 100C_1, 100D_1, 100D_2, and 100D_3 includes the same circuit elements as headset device 100, provides the same functions and operations, and is able to detect whether the distance between itself and any other headset device is greater than a specific distance threshold to determine whether to enter the walkie-talkie mode. For example, headset device 100A_1 is outside the signal range of headset devices 100D_1, 100D_2, and 100D_3; however, this is not a limitation of this application.

[0060] For example, the headsets 100A_1, 100A_2, 100D_1, 100D_2, and 100D_3 used by users UA1, UA2, UD1, UD2, and UD3, respectively, are classified into the same voice groups based on unique information of these devices, such as MAC addresses, and multiple corresponding MAC addresses (but not limited to) of mobile devices 110A and 110D, using specific application software. Multiple voice packets in this walkie-talkie mode can be relayed by mobile devices 110B and 110C through multiple intermediate Bluetooth communication connections. These signals record the destination address in the multi-hop network (i.e., the MAC addresses of mobile devices 100A and 100D), and therefore can be correctly transmitted between mobile devices 110B and 110C. Additionally, for example, the headset devices 100B_1, 100B_2, and 100C_1 used by users UB1, UB2, and UC1 respectively, will be classified into another voice group based on their unique information, such as MAC addresses, and the MAC addresses (but not limited to) of the corresponding mobile devices 110B and 110C, using a specific application software. Multiple voice packets in this walkie-talkie mode can then be transmitted between mobile devices 110B and 110C. These signals record the destination address in the multi-hop network (i.e., the MAC addresses of mobile devices 100B and 100C), thus ensuring correct transmission between mobile devices 100B and 100C without being transmitted to mobile devices 100A and 100D. The operation of relaying or forwarding a voice packet signal based on the MAC address of the mobile phone at the destination device is similar to... Figure 6 The operation of the embodiments will not be repeated here to simplify the description.

[0061] In one embodiment, the multiple voice packets of the walkie-talkie mode can be transmitted via a specific wireless communication standard different from the Bluetooth communication standard, wherein the specific wireless communication standard may refer to a wireless local area network (WLAN) or a wireless broadband communication standard (but is not limited thereto). Figure 6 This is an example illustration illustrating how multiple users / persons corresponding to the same voice group, according to an embodiment of this application, can communicate with each other in the walkie-talkie mode by using a station with a different wireless communication standard to forward or relay multiple voice packet signals of the same walkie-talkie mode. Figure 3 As shown, mobile devices 110A, 110B, 110C, and 110D can wirelessly connect to one or more base stations 130 in a wireless communication system based on communication through a wireless local area network system or a wireless broadband system. Mobile devices 110A, 110B, 110C, and 110D can connect to each other via Internet communication and through one or more base stations 130. Each of these headset devices 100A_1, 100B_1, 100B_2, 100C_1, 100C_2, 100C_3, 100B_4, 100B_5, 100C_6, 100B_7, 100B_8, 100B_9, 100B_1, 100B_1, 100C_1, 100B_2, 100C_1, 100B_2, 100C_3, 100B_4, 100B_5, 100B_6, 100B_7, 100B_8, 100B_9, 100B_1, 100B_1, 100B_2, 100C_1, 100B_2, 100B_3, 100B_4, 100B_5, 100B_6, 100B_7, 100B_8, 100B_9, 100B_1, 100B_2, 100B_1, 100B_2, 100B_3, 100B_4, 100B_5, 100B_6, 100B_7, 100B_8, 100B_9, 100B_1, 10 Both 2 and 100D_1 contain the same circuit elements as headset device 100, provide the same functions and operations, and are able to detect whether the distance between themselves and any headset device is greater than a specific distance threshold to determine whether to enter the walkie-talkie mode. For example, headset device 100A_1 is outside the signal range of headset devices 100B1_1, 100B_2, 100C_1, 100C_2, and 100D_1. However, this is not a limitation of this application.

[0062] For example, the headset devices 100A_1, 100B_1, 100B_2, 100C_1, 100C_2, and 100D_1 used by users UA1, UB1, UB2, UC1, UC2, and UD1, respectively, are classified into the same voice groups based on their unique information, such as MAC addresses (but not limited to), and by using a specific application. Multiple voice packets in this walkie-talkie mode can be relayed through base station 130. For example, the multiple voice packets in this walkie-talkie mode of Bluetooth communication can be transmitted between one or more mobile devices. The data packet signal (carrying the content of the voice packet) can be transmitted through the base station 130 using the wireless local area network system or wireless broadband system. In one embodiment, initially, the transmission of multiple voice packet signals in the walkie-talkie mode can be carried out by direct transmission between the headset devices. If the direct transmission fails, the transmission can be attempted by multiple Bluetooth communications between multiple mobile devices in a Bluetooth multi-hop network. If the Bluetooth communication between the mobile devices also fails, the multiple voice packet signals can be transmitted and relayed by communication based on the Internet.

[0063] The operation of recording information in the information database INFO1 of each headset device 100A_1, 100B_1, 100B_2, 100C_1, 100C_2, and 100D_1 is similar to the aforementioned operation and will not be repeated. Furthermore, in other embodiments, headset devices (e.g., 100A_1, 100B_1, and 100B_2) corresponding to a subset of users such as UA1, UB1, and UB2 can be classified into one voice group, while headset devices (e.g., 100C_1, 100C_2, and 100D_1) corresponding to another subset of users such as UC1, UC2, and UD1 can be classified into another different voice group. Multiple voice packet signals from different voice groups can be relayed or relayed through the base station 130 respectively.

[0064] Furthermore, in other embodiments, the wearable electronic device 100 worn by a user, such as an earphone / earpiece device (but not limited to), can also be used to determine whether a user / person (corresponding to the wearable electronic device 100 itself) has come into contact with one or more different people (corresponding to one or more other different wearable electronic devices). In embodiments, the definition of a person coming into contact with one or more other people may include at least one of the following events: the person has physical contact with at least one different person; the person enters the personal / proxemics space of at least one different person but does not have physical contact with the at least one different person; the person talks or converses with at least one different person within a short distance but does not have physical contact with the at least one different person; the person makes eye contact with at least one different person within a short distance but does not talk or converse; the person faces at least one different person within a short distance; and so on.

[0065] To determine whether a person has come into contact with one or more other different people, the wearable electronic device 100 (or processing circuit 101) can detect the distance between the wearable electronic device 100 and one or more other wearable electronic devices used or carried by one or more other different people, compare the detected distance with a specific distance threshold, and if the detected distance is less than or becomes less than the specific distance threshold, the wearable electronic device 100 can determine that the person has come into contact with one or more other different people; conversely, if the detected distance is greater than or becomes greater than the specific distance threshold, the wearable electronic device 100 will determine that the person has not come into contact with one or more other different people. In this way, the wearable electronic device 100 can also determine whether it is adjacent to one or more other wearable electronic devices. The specific distance threshold is, for example, equal to 1 meter, 1.5 meters, 2 meters, or 3 meters (but not limited). If it has been determined that a different wearable electronic device is adjacent to the wearable electronic device 100, the wearable electronic device 100 can determine that another person using or carrying the different wearable electronic device may be within the personal space of the person using the wearable electronic device 100. In this case, the wearable electronic device 100 will determine that the person using the wearable electronic device 100 may have come into contact with another person using / carrying the different wearable electronic device.

[0066] In other embodiments, to determine whether a person using the wearable electronic device 100 is in contact with another person using / carrying a different wearable electronic device, the wearable electronic device 100 may also employ the Bluetooth direction finding capability to determine whether the person / user using the wearable electronic device 100 is facing the face of one or more different people using / carrying one or more different wearable electronic devices. In practice, the wearable electronic device 100 can calculate the head rotation angle of the person using the wearable electronic device 100 and can also calculate the angle of arrival or departure angle of one or more signals from one or more different wearable electronic devices, and thereby determine whether the person / user using the wearable electronic device 100 is facing the face of one or more other people based on the head rotation angle and the angle of arrival or departure angle. Furthermore, in other embodiments, the wearable electronic device 100 and the one or more different wearable electronic devices can respectively calculate the head rotation angle of the corresponding person / user of these devices, and then exchange or share the head rotation angle information with each other in real time or periodically to determine whether the person or user corresponding to these devices is face-to-face. If it is determined that the person / user using device 100 is facing the face of one or more other users within a short range, the wearable electronic device 100 can determine that the person / user using device 100 has had conversation / dialogue and / or eye contact with one or more other people in a personal space, thereby determining that the person / user using device 100 has made contact with one or more other people. It should be noted that the wearable electronic device can also use the distance detection operation between two wearable electronic devices to accurately or precisely detect and determine whether the person / user using device 100 has had conversation / dialogue and / or eye contact with one or more other people within a specific distance range, and this type of embodiment variation is not a limitation of this application.

[0067] Furthermore, to calculate the total contact time, in practice, the wearable electronic device 100 can calculate or determine the total contact time by setting a start time when the detected distance becomes less than the specific distance threshold and an end time when the detected distance becomes greater than the specific distance threshold. In one embodiment, the wearable electronic device 100 can also calculate the total contact time using the Bluetooth direction finding capability. For example, the start point of the total contact time may correspond to the time when the people / users are becoming face-to-face and the end point of the total contact time may correspond to the time when the people / users are becoming no longer face-to-face, and this type of embodiment variation is not a limitation of this application.

[0068] After determining that the person using the wearable electronic device 100 has come into contact with one or more different people carrying or using one or more other different devices, the wearable electronic device 100 can record the unique information of the one or more different wearable electronic devices (e.g., device identification ID) and / or the total contact time corresponding to the one or more different wearable electronic devices in the memory 103 as contact information. This contact information can be transmitted via Bluetooth communication to and stored in the memory of the mobile phone device 110 used by the person / user. Such contact information is used to generate or form the person's contact history.

[0069] For example, in Figure 4 In this context, the headset device 100_1 uses distance detection and / or Bluetooth direction finding capabilities to determine that the person using the headset device 100_1 has made contact with another person using the headset device 100_2. Therefore, the unique information of the headset device 100_2 and / or the corresponding total contact time are stored in the headset device 100_1 as contact information, and this contact information can also be transmitted and stored in the mobile phone device 110. It should be noted that unique information of other headset devices (e.g., device 100_3 used by a user / person U3 who has not made contact with person U1) will not be stored in the headset device 100_1 as contact information.

[0070] Furthermore, in one embodiment, the contact information may additionally include unique information about a user / person corresponding to different wearable electronic devices and / or unique information about a different type of electronic device (e.g., a mobile phone or smartphone) corresponding to those different wearable electronic devices. For example, in Figure 7 If the headset device 100A_2 used by user UA2 determines that user UA2 has contacted user UB1 using headset device 100B_1, then headset device 100A_2 will send a request to the different wearable electronic device (i.e., headset device 100B_1) to request a response with unique information related to user UB1 and / or a response with unique information from a different type of electronic device (e.g., mobile phone device 110B) corresponding to the different wearable electronic device 100B_1. If the aforementioned unique information can be exchanged or shared, headset device 100A_2 will store the unique information in memory 103 as contact information after receiving it. The aforementioned unique information can also be transmitted from headset device 100A_2 to mobile phone device 110A, so that user UA2 using mobile phone device 110A can also know his / her contact history.

[0071] Therefore, if a person / user using the mobile device 110 is identified as a suspected or confirmed case in the future, the aforementioned contact history can be provided and disclosed to the hospital or relevant government departments. Based on the complete contact history information recorded and generated by the wearable electronic device, it is easy to determine who is more likely to be infected by the user / person using the wearable electronic device, so as to identify and prevent the spread of the disease early.

[0072] Compared to previous technologies, this wearable electronic device can accurately determine whether a person has spoken / conversed with others and / or made eye contact, and / or whether a person has entered another person's personal space (i.e., whether they have been very close to another person), based on precise distance detection and Bluetooth direction finding, thus determining whether that person has been in contact with other people. In this way, because traditional location tracking systems, such as Wi-Fi systems, can only provide a certain level of tracking accuracy, with a range of approximately 3 to 5 meters, the performance of this application's technology in detecting contact history is significantly improved compared to traditional technologies.

[0073] Furthermore, the wearable electronic device 100 may also use distance detection and / or Bluetooth direction finding capabilities to calculate and collect a travel history of the person / user using the wearable electronic device 100 itself. In related embodiments, the travel history includes at least one of the activity route and activity time of the person / user using the wearable electronic device 100 itself. Figure 7 This is an example illustration illustrating how the Bluetooth direction finding capability of a wearable electronic device 100 is used to generate and obtain the travel history of a person / user using the wearable electronic device 100, according to an embodiment of this application. Figure 7 As shown, multiple Bluetooth locator stations with Bluetooth communication capabilities (referred to as 'A1', 'A2', 'A3' through 'A10', but not limited to this) are set up in one location (e.g., Figure 7 Different locations within a tourist factory (but not limited to). In one embodiment, a visitor (denoted as 'Δ'), for example, a user / person using or carrying the wearable electronic device 100, enters the tourist factory to experience its history, personally experience the assembly line and manufacturing process up close, and enjoy shopping and dining opportunities, where R2 represents a walking route of visitor 'Δ', while other visitors / persons are represented by different symbols ''.

[0074] The wearable electronic device 100 or mobile phone device 110 can generate an estimate of a head rotation angle by detecting and calculating the aforementioned rotation angle information in real time. This estimate can indicate whether the person / user is facing the camera directly.​ The diagram shows one or more Bluetooth locator stations. For example, the visitor 'Δ' passes through different locations set up by these different Bluetooth locator stations ('A1', 'A2', 'A3' to 'A10'). For instance, the visitor 'Δ' might be located at or arrive at the location set up by Bluetooth locator station 'A1' at 2 PM. In this case, the wearable electronic device 100 can use distance detection and / or Bluetooth direction finding capabilities to detect the distance between the wearable electronic device 100 and Bluetooth locator station 'A1' and / or detect whether the visitor 'Δ' becomes facing Bluetooth locator station 'A1' to determine whether that location is a contact area for the visitor 'Δ'. For example, when the detected distance is less than a specific distance threshold, such as 1 meter, 1.5 meters, or 2 meters (but not limited to), and / or when the visitor 'Δ' becomes facing the Bluetooth locator station 'A1', the wearable electronic device 100 can determine that the corresponding location is the visitor 'Δ's contact area. Then, if the location is determined to be a contact area, the wearable electronic device 100 can store the corresponding location information, arrival time, total stay / contact time, and departure time in its own memory. The travel information stored in the memory can then be provided and transmitted in real-time and / or periodically to the mobile device 110 used by the visitor 'Δ' to generate and display a travel history record for the visitor 'Δ', so that if a suspected or confirmed case has entered the tourist factory, the visitor 'Δ' can know, based on their travel history record, whether they have ever been to the contact area / location of the suspected or confirmed case.

[0075] Furthermore, the Bluetooth locator station 'A1' can also use distance detection and / or Bluetooth direction finding capabilities to detect the distance between the wearable electronic device 100 and the Bluetooth locator station 'A1' and / or detect whether the visitor 'Δ' becomes facing the Bluetooth locator station 'A1', in order to determine and record information about the person, wearable electronic device, and / or mobile device who has been to or visited this place / location. For example, when the same method is used to determine that this place / location is a contact area of ​​the visitor 'Δ', the Bluetooth locator station 'A1' can record the unique information of the visitor 'Δ', the unique information of the wearable electronic device 100, and / or the unique information of the mobile device 110. Furthermore, the Bluetooth locator station 'A1' can also record the visitor 'Δ's corresponding arrival time, total stay / contact time, and departure time.

[0076] Similarly, for each different Bluetooth locator station 'A2', 'A3' to 'A10', the wearable electronic device 100 can determine whether the corresponding location of each Bluetooth locator station is a contact area of ​​the visitor 'Δ', and when it is determined that the location is a contact area of ​​the visitor 'Δ', it can store the corresponding information of the location (e.g., location information, arrival time, total stay / contact time and / or departure time). Each Bluetooth locator station can also determine whether its location is a contact area of ​​the visitor 'Δ', and can also record and store the corresponding information, such as the unique information of the visitor 'Δ', the unique information of the wearable electronic device 100 and / or the unique information of the mobile device 110, the corresponding arrival time of the visitor 'Δ', the total stay / contact time and / or departure time, etc.

[0077] If visitor 'Δ' is identified as a suspected or confirmed case in the future, the travel information of visitor 'Δ' recorded or stored in one or more Bluetooth locator stations that they have come into contact with or passed by can provide the travel history for visitor 'Δ'. This travel history can then be provided to and disclosed to hospitals or relevant government departments, making it easier to identify who is more likely to be infected, so as to identify and prevent the spread of the disease early.
