[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0021] Currently, two electronic devices can interact with each other. For example, two electronic devices can include a smartphone and headphones, which can then interact via Bluetooth or a wired connection. Method 1: The headphones are wired to the smartphone, with the headphone plug connected to the smartphone's jack. This allows the audio signals from the smartphone to be transmitted to the headphones, and the audio signals are output through the headphones' speakers. Method 2: The headphones are wireless Bluetooth headphones, which connect to the smartphone via Bluetooth.

[0022] For Method 2, the current data transmission and connection establishment process is as follows: 1. Bluetooth broadcast - device discovery; 2. Pairing and binding devices; 3. Establishing a connection; 4. Data communication. Broadcasting is conducted on Bluetooth frame formats via broadcast channels 37, 38, and 39. A single broadcast packet is a maximum of 37 bytes, consisting of a MAC address and N AD structures. If the data is less than 37 bytes, it can be padded. Upon receiving a scan_req, the broadcaster can send a scan_rsp response message on the same channel, which is completed within a specified time. After transmitting a broadcast packet, the advertiser needs to open a radio frequency reception window for a period of time to receive data packets from the observer. During this time, the observer can send connection requests to the advertiser. After the host scans and detects the slave device, it sends a connect_req connection request.

[0023] In wireless communication between smartphones and headphones, the transmission of wireless audio involves communication between the smartphone and both headphones. Regardless of whether the smartphone is held in hand, on a table, or in a pocket, it remains on one side of the user's body. The signal from the headphones on the opposite side of the body is obstructed and attenuated, inevitably leading to a significant decrease in signal strength and a drop in audio bitrate. Using binaural relay, however, consumes bandwidth and cannot completely solve the problem.

[0024] To address the aforementioned problems, the inventors, through long-term research, discovered and proposed the data interaction method, apparatus, electronic device, and storage medium provided in the embodiments of this application. By constructing a data interaction channel between electronic devices based on electric field human body communication technology when the electronic device requiring data interaction is close to the target human body and located on different sides of the target human body, the obstruction of the human body can be reduced, and the data transmission rate can be improved. The specific data interaction method will be described in detail in the subsequent embodiments.

[0025] The following describes the application scenarios that can be used for the data interaction methods provided in the embodiments of this application.

[0026] Please see Figure 1 , Figure 1A schematic diagram illustrating an application scenario that can be used for the data interaction method provided in the embodiments of this application is shown. For example... Figure 1 As shown, it includes a first electronic device 100, which is used to interact with a second electronic device 200. The first electronic device 100 may include a smartphone, tablet, earphones, smart ring, smartwatch, smart glasses, heart rate monitor, wristband, bracelet, etc., and is not limited thereto. Figure 1 Taking a smartphone as an example, the first electronic device 100 may include, but is not limited to, smartphones, tablets, earphones, smart rings, smartwatches, smart glasses, heart rate monitors, wristbands, bracelets, etc. Figure 1 Taking the second electronic device 200 as an example, which is a headset. Figure 1 As shown, the first electronic device 100 can be held in the hand of the user (target human body), and the second electronic device 200 can be worn on the ear of the user (target human body).

[0027] The first electronic device 100 can be used as a signal source for the second electronic device 200. For example, the first electronic device 100 can be used as an audio source, a health data source, etc. for the second electronic device, without limitation.

[0028] Please see Figure 2 , Figure 2 A schematic diagram showing the equivalent capacitance formed between the first electronic device and the target human body is shown. Figure 2 As shown, the first electronic device 100 may include an electrode antenna, which is used to form an equivalent capacitance / electric field with the human body for data transmission based on the equivalent capacitance / electric field. That is, the first electronic device 100 is used to transmit data based on the equivalent capacitance / electric field, and the second electronic device 200 is used to receive data.

[0029] Please see Figure 3 , Figure 3 A schematic diagram illustrating the equivalent capacitance formed between the second electronic device and the target human body is shown. Figure 3As shown, the second electronic device 200 may include a microcontroller unit (MCU) for system logic processing and routine detection, such as headphone insertion detection, opening detection, and touch event judgment; a codec for audio data encoding and decoding; a power amplifier and speaker for outputting sound that can be perceived by the human ear; and Wi-Fi (Wireless-Remote Communication), a human body electric field communication technology. Wi-Fi, in conjunction with electrodes / antennas, is used for data transmission. These electrodes / antennas form an equivalent capacitance with the human body for data transmission. The antenna can share a design with a conventional Bluetooth antenna, which can better save the size of the second electronic device 200. Optionally, the Wi-Fi operating frequency is between 1MHz and 20MHz.

[0030] Please see Figure 4 , Figure 4 A flowchart illustrating a data interaction method according to an embodiment of this application is shown. This method is used to construct a data interaction channel between electronic devices when the electronic device requiring data interaction is close to the target human body and located on different sides of the target human body. This reduces human body obstruction and improves data transmission rate. In a specific embodiment, this data interaction method is applied to, for example... Figure 8 The data interaction device 300 and the first electronic device 100 equipped with the data interaction device 300 are shown. Figure 9 The following will use a first electronic device as an example to illustrate the specific process of this embodiment. Of course, it is understood that the first electronic device used in this embodiment may include smartphones, tablets, wearable electronic devices, etc., and is not limited thereto. In this embodiment, the first electronic device is used for data interaction with the second electronic device. The following will focus on... Figure 4 The process shown will be described in detail. The data interaction method may specifically include the following steps:

[0031] Step S110: Determine the first distance relationship between the first electronic device and the target human body and a first distance threshold, and determine the second distance relationship between the second electronic device and the target human body and a second distance threshold.

[0032] Optionally, the target human body can be a human body that corresponds to the first electronic device and the second electronic device. For example, if the first electronic device and / or the second electronic device are in a wearing state, the human body wearing the first electronic device and / or the second electronic device can be identified as the target human body; if the first electronic device and / or the second electronic device are in a holding state, the human body held by the first electronic device and / or the second electronic device can be identified as the target human body; or, the human body closest to the first electronic device and / or the second electronic device can be identified as the target human body, etc., without limitation.

[0033] In this embodiment, the distance between the first electronic device and the target human body can be determined as a first distance, and the distance relationship between the first distance and a distance threshold can be determined as a first distance relationship. This first distance relationship may include: the first distance is less than the distance threshold, the first distance is equal to the distance threshold, or the first distance is greater than the distance threshold.

[0034] The distance threshold can be the maximum distance within the range of the human body's electric field (the range relative to the surface of the human skin). That is, if the initial distance between the first electronic device and the target human body is less than the distance threshold, it can be considered that the distance between the first electronic device and the target human body meets the effective range for the transmission of the human body's electric field, and an effective human body electric field can be formed between the first electronic device and the target human body. If the initial distance between the first electronic device and the target human body is equal to or greater than the distance threshold, it can be considered that the distance between the first electronic device and the target human body does not meet the effective range for the transmission of the human body's electric field, and an effective human body electric field cannot be formed between the first electronic device and the target human body. Optionally, the distance threshold can include 10cm, 15cm, etc., and is not limited here.

[0035] In some implementations, the first electronic device may include a first distance sensor. Based on this, the first distance sensor of the first electronic device can detect a first distance between the first electronic device and the target human body, and compare the detected first distance with a pre-set and stored distance threshold to determine a first distance relationship between the first distance and the distance threshold.

[0036] In this embodiment, the distance between the second electronic device and the target human body can be determined as a second distance, and the distance relationship between the second distance and a distance threshold can be determined as a second distance relationship. This second distance relationship can include: the second distance is less than the distance threshold, the second distance is equal to the distance threshold, or the second distance is greater than the distance threshold.

[0037] The distance threshold can be the maximum distance within the range of the human body's electric field. That is, if the second distance between the second electronic device and the target human body is less than the distance threshold, it can be considered that the distance between the second electronic device and the target human body meets the effective range for the transmission of the human body's electric field, and an effective human body electric field can be formed between the second electronic device and the target human body. If the second distance between the second electronic device and the target human body is equal to or greater than the first distance threshold, it can be considered that the distance between the second electronic device and the target human body does not meet the effective range for the transmission of the human body's electric field, and an effective human body electric field cannot be formed between the second electronic device and the target human body. Optionally, the distance threshold can include 10cm, 15cm, etc., and is not limited here.

[0038] In some implementations, the second electronic device may include a second distance sensor. Based on this, the second distance sensor of the second electronic device can detect a second distance between the second electronic device and the target human body, and compare the detected second distance with a pre-set and stored distance threshold to determine a second distance relationship between the second distance and the distance threshold.

[0039] As one possible approach, if the second electronic device obtains a second distance relationship with the distance threshold, it can send the second distance relationship to the first electronic device via broadcast or Bluetooth. Accordingly, the first electronic device can obtain the second distance relationship, which is not limited here.

[0040] Step S120: Determine the positional relationship between the first electronic device and the second electronic device and the target human body.

[0041] In this embodiment, the positional relationship between the first electronic device and the second electronic device and the target human body can be determined. This positional relationship can include: the first electronic device and the second electronic device being located on the same side of the target human body, or the first electronic device and the second electronic device being located on different sides of the target human body. Optionally, when the first electronic device and the second electronic device are located on different sides of the target human body, the first electronic device can be located on the left side of the target human body, and the second electronic device can be located on the right side of the target human body; the first electronic device can be located in front of the target human body, and the second electronic device can be located on the left side of the target human body, etc., without limitation.

[0042] It can be understood that if the positional relationship indicates that the first electronic device and the second electronic device are located on the same side of the target human body, it can be assumed that the first electronic device and the second electronic device will not be obstructed by the target human body during the data transmission process via wireless means such as Bluetooth; if the positional relationship indicates that the first electronic device and the second electronic device are located on different sides of the target human body, it can be assumed that the first electronic device and the second electronic device will be obstructed by the target human body during the data transmission process via wireless means such as Bluetooth.

[0043] In some implementations, a first positional relationship between a first electronic device and a target human body can be obtained, and a second positional relationship between a second electronic device and a target human body can be obtained. Based on the first and second positional relationships, the positional relationship between the first electronic device, the second electronic device, and the target human body can be determined.

[0044] As one feasible approach, the first electronic device may determine the first positional relationship with the target human body through ultrasonic positioning technology; through radar positioning technology; through infrared positioning technology; through RFID positioning technology; or through image recognition technology, etc., without limitation.

[0045] As one feasible approach, the second electronic device can determine the second positional relationship with the target human body through ultrasonic positioning technology; through radar positioning technology; through infrared positioning technology; through RFID positioning technology; or through image recognition technology, etc., without limitation.

[0046] In one approach, if the second electronic device obtains a second positional relationship with the target human body, it can send the second positional relationship to the first electronic device via broadcast or Bluetooth. Accordingly, the first electronic device can obtain the second positional relationship, without any limitation.

[0047] Step S130: If it is determined that the first distance is less than a distance threshold based on the first distance relationship, the second distance is less than the distance threshold based on the second distance relationship, and the first electronic device and the second electronic device are located on different sides of the target human body based on the position relationship, then a data interaction channel between the first electronic device and the second electronic device is constructed based on electric field human body communication technology.

[0048] In this embodiment, given the first distance relationship, the second distance relationship, and the positional relationship, it is possible to determine whether the first distance is less than a distance threshold based on the first distance relationship, whether the second distance is less than a distance threshold based on the second distance relationship, and whether the first electronic device and the second electronic device are located on different sides of the target human body based on the positional relationship. Specifically, if the first distance is determined to be less than the distance threshold based on the first distance relationship, it can be determined that an effective human body electric field can be formed between the first electronic device and the target human body; if the second distance is determined to be less than the distance threshold based on the second distance relationship, it can be determined that an effective human body electric field can be formed between the second electronic device and the target human body; if the positional relationship determines whether the first electronic device and the second electronic device are located on different sides of the target human body, it can be determined that data transmission between the first electronic device and the second electronic device via wireless means such as Bluetooth would be obstructed by the target human body. Therefore, a data interaction channel between the first electronic device and the second electronic device can be constructed based on electric field human body communication technology, which can reduce human body obstruction and improve the efficiency of human body data transmission.

[0049] Among them, electric field human body communication technology is a communication technology that uses the human body as a communication channel for signal transmission. This technology establishes an electric field on or inside the human body, coupling signals to the body to achieve signal transmission and exchange. It can be understood that electric field human body communication technology can achieve low-frequency signal transmission. This technology uses low-frequency signals for transmission, typically between tens and hundreds of hertz. The low-frequency signal establishes an electric field on or inside the human body to achieve signal transmission. Electric field human body communication technology can achieve signal enclosure. Because it uses low-frequency signals, the signal propagation distance is short, usually only a few centimeters to a few meters. Therefore, the signal confidentiality is good and it is not easily interfered with or eavesdropped on by external forces. Electric field human body communication technology can achieve high reliability. Because the signal transmission of electric field human body communication technology takes place inside the human body, it is not affected by the external environment, thus possessing high reliability.

[0050] In the case of constructing a data interaction channel between a first electronic device and a second electronic device based on electric field human body communication technology, the first electronic device can modulate the signal to be transmitted and convert it into a signal form suitable for transmission. Then, the first electronic device uses electrodes or sensors to couple the signal to the target human body, establishing an electric field inside the human body. The signal propagates in the electric field inside the target human body. Since the human body itself has certain electrical characteristics such as resistance and capacitance, it can have a certain influence on the electric field. The signal can be transmitted with changes in distance and human posture. The second electronic device can use another set of electrodes or sensors to receive the signal transmitted from inside the target human body, demodulate it, and restore it to the original signal. Afterwards, the second electronic device can further process and apply the received signal, such as playback.

[0051] An embodiment of this application provides a data interaction method that determines a first distance relationship between a first electronic device and a target human body and a first distance threshold, and a second distance relationship between a second electronic device and a target human body and a second distance threshold. It also determines the positional relationship between the first electronic device, the second electronic device, and the target human body. If, based on the first distance relationship, the first distance is determined to be less than the distance threshold; based on the second distance relationship, the second distance is determined to be less than the distance threshold; and based on the positional relationship, the first electronic device and the second electronic device are determined to be located on different sides of the target human body, a data interaction channel between the first electronic device and the second electronic device is constructed based on electric field human body communication technology. Therefore, by constructing a data interaction channel between electronic devices based on electric field human body communication technology when the electronic devices requiring data interaction are close to the target human body and located on different sides of the target human body, human body obstruction can be reduced, and data transmission rate can be improved.

[0052] Please see Figure 5 , Figure 5 A flowchart illustrating a data interaction method according to an embodiment of this application is shown. This method is applied to the aforementioned first electronic device, which is used to interact with a second electronic device. The following will focus on... Figure 5 The process shown will be described in detail. The data interaction method may specifically include the following steps:

[0053] Step S210: Obtain the first state of the first electronic device.

[0054] In this embodiment, the state of the first electronic device can be obtained and the state of the first electronic device can be determined as the first state.

[0055] In some implementations, the first electronic device may include a first pressure sensor, which can be used to detect and obtain the first state of the first electronic device. For example, the first pressure sensor can detect the location where the first electronic device receives a press, and the first state of the first electronic device can be obtained based on the location where the first electronic device receives a press.

[0056] In some implementations, the first electronic device may include a first contact sensor, which can be used to detect and obtain the first state of the first electronic device. For example, the first contact sensor can be used to detect the location where the first electronic device receives a touch, and the first state of the first electronic device can be obtained based on the location where the first electronic device receives a touch.

[0057] In some implementations, the first electronic device may include a first attitude sensor, which can be used to detect and obtain the first state of the first electronic device. For example, the first attitude of the first electronic device can be detected by the first attitude sensor, and the first state of the first electronic device can be obtained based on the first attitude.

[0058] Step S220: If it is determined based on the first state that the first electronic device is in a wearing state or a holding state, then it is determined that the first distance is less than the distance threshold.

[0059] In this embodiment, when the first state of the first electronic device is obtained, it can be determined whether the first electronic device is in a wearing state or a holding state based on the first state. If it is determined that the first electronic device is in a wearing state or a holding state based on the first state, it can be determined that the first distance is less than a distance threshold.

[0060] In some implementations, if the first state of the first electronic device is determined by data detected by the first pressure sensor, then the pressing position detected by the first pressure sensor can be compared with the pressing position when the first electronic device is in a wearing or holding state. If the comparison result indicates that the pressing position matches the pressing position when the first electronic device is in a wearing or holding state, then it can be determined that the first electronic device is in a wearing or holding state, and that the first distance is less than a distance threshold.

[0061] In some implementations, if the first state of the first electronic device is determined by data detected by the first touch sensor, then the touch position detected by the first touch sensor can be compared with the touch position when the first electronic device is in a wearing state or a holding state. If the comparison result indicates that the touch position matches the touch position when the first electronic device is in a wearing state or a holding state, then it can be determined that the first electronic device is in a wearing state or a holding state, and that the first distance is less than a distance threshold.

[0062] In some implementations, if the first state of the first electronic device is determined by data detected by the first attitude sensor, then the attitude data detected by the first attitude sensor can be compared with the attitude data when the first electronic device is in a wearing state or a holding state. If the comparison result indicates that the attitude data matches the attitude data when the first electronic device is in a wearing state or a holding state, then it can be determined that the first electronic device is in a wearing state or a holding state, and that the first distance is less than a distance threshold.

[0063] Step S230: Obtain the second state of the second electronic device.

[0064] In this embodiment, the state of the second electronic device can be obtained and the state of the second electronic device can be determined as the second state.

[0065] In some implementations, the second electronic device may include a second pressure sensor, which can be used to detect and obtain the second state of the second electronic device. For example, the second pressure sensor can detect the location where the second electronic device receives a press, and the second state of the second electronic device can be obtained based on the location where the second electronic device receives a press.

[0066] In some implementations, the second electronic device may include a second contact sensor, which can be used to detect and obtain the second state of the second electronic device. For example, the second contact sensor can detect the location where the second electronic device receives a touch, and the second state of the second electronic device can be obtained based on the location where the second electronic device receives a touch.

[0067] In some implementations, the second electronic device may include a second attitude sensor, which can be used to detect and acquire the second state of the second electronic device. For example, the second attitude of the second electronic device can be detected by the second attitude sensor, and the second state of the second electronic device can be acquired based on the second attitude.

[0068] Step S240: If it is determined based on the second state that the second electronic device is in a wearing state or a holding state, then it is determined that the second distance is less than the distance threshold.

[0069] In this embodiment, when the second state of the second electronic device is obtained, it can be determined whether the second electronic device is in a wearing state or a holding state based on the second state. If it is determined that the second electronic device is in a wearing state or a holding state based on the second state, it can be determined that the second distance is less than a distance threshold.

[0070] In some implementations, if the second state of the second electronic device is determined by data detected by the second pressure sensor, then the pressing position detected by the second pressure sensor can be compared with the pressing position when the second electronic device is in a wearing or holding state. If the comparison result indicates that the pressing position matches the pressing position when the second electronic device is in a wearing or holding state, then it can be determined that the second electronic device is in a wearing or holding state, and that the second distance is less than a distance threshold.

[0071] In some implementations, if the second state of the second electronic device is determined by data detected by the second touch sensor, then the touch position detected by the second touch sensor can be compared with the touch position when the second electronic device is in a wearing or holding state. If the comparison result indicates that the touch position matches the touch position when the second electronic device is in a wearing or holding state, then it can be determined that the second electronic device is in a wearing or holding state, and that the second distance is less than a distance threshold.

[0072] In some implementations, if the second state of the second electronic device is determined by data detected by the second attitude sensor, then the attitude data detected by the second attitude sensor can be compared with the attitude data when the second electronic device is in a wearing state or a holding state. If the comparison result indicates that the attitude data matches the attitude data when the second electronic device is in a wearing state or a holding state, then it can be determined that the second electronic device is in a wearing state or a holding state, and that the second distance is less than a distance threshold.

[0073] Step S250: Determine the positional relationship between the first electronic device and the second electronic device and the target human body.

[0074] Step S260: If it is determined that the first distance is less than a distance threshold based on the first distance relationship, the second distance is less than the distance threshold based on the second distance relationship, and the first electronic device and the second electronic device are located on different sides of the target human body based on the position relationship, then a data interaction channel between the first electronic device and the second electronic device is constructed based on electric field human body communication technology.

[0075] For a detailed description of steps S250-S260, please refer to steps S120-S130, which will not be repeated here.

[0076] The data interaction method provided in one embodiment of this application is compared to... Figure 4 The data interaction method shown in this embodiment also obtains the first state of the first electronic device, and when the first state indicates that the first electronic device is in a wearing state or a holding state, determines that the distance between the first electronic device and the target human body is less than a distance threshold. It also obtains the second state of the second electronic device, and when the second state indicates that the second electronic device is in a wearing state or a holding state, determines that the distance between the second electronic device and the target human body is less than a distance threshold, thereby improving the accuracy of the determined distance relationship.

[0077] Please see Figure 6 , Figure 6A flowchart illustrating a data interaction method according to an embodiment of this application is shown. This method is applied to the aforementioned first electronic device, which is used to interact with a second electronic device. The following will focus on... Figure 6 The process shown will be described in detail. The data interaction method may specifically include the following steps:

[0078] Step S310: Determine the data type corresponding to the data to be transmitted from the first electronic device to the second electronic device.

[0079] In this embodiment, the data type corresponding to the data to be transmitted from the first electronic device to the second electronic device can be determined.

[0080] One approach is to obtain the data format corresponding to the data to be transmitted from the first electronic device to the second electronic device, and based on this data format, determine the data type corresponding to the data to be transmitted from the first electronic device to the second electronic device.

[0081] As another method, the application corresponding to the data to be transmitted from the first electronic device to the second electronic device can be obtained, and the data type corresponding to the data to be transmitted from the first electronic device to the second electronic device can be determined based on the application.

[0082] Step S320: If the data type includes audio type, then determine the first distance relationship between the first distance and the distance threshold, and determine the second distance relationship between the second distance and the distance threshold.

[0083] In this embodiment, after determining the data type of the data to be transmitted from the first electronic device to the second electronic device, it can be determined whether the data type includes audio. If the data type includes audio, a first distance relationship between a first distance and a distance threshold can be determined, and a second distance relationship between a second distance and a distance threshold can be determined. This facilitates the subsequent implementation of a data interaction channel between the first and second electronic devices using electric field human body communication technology, thereby improving the transmission effect of audio data. If the data type does not include audio (e.g., includes health data types), a wireless (e.g., Bluetooth) connection between the first and second electronic devices can be directly established.

[0084] Step S330: Determine the positional relationship between the first electronic device and the second electronic device and the target human body.

[0085] Step S340: If it is determined that the first distance is less than a distance threshold based on the first distance relationship, the second distance is less than the distance threshold based on the second distance relationship, and the first electronic device and the second electronic device are located on different sides of the target human body based on the position relationship, then a data interaction channel between the first electronic device and the second electronic device is constructed based on electric field human body communication technology.

[0086] For a detailed description of steps S330-S340, please refer to steps S120-S130, which will not be repeated here.

[0087] The data interaction method provided in one embodiment of this application is compared to... Figure 4 The data interaction method shown in this embodiment further determines the data type corresponding to the data to be transmitted from the first electronic device to the second electronic device, and constructs a data interaction channel between electronic devices based on electric field human body communication technology when the data type includes audio type, thereby ensuring the transmission rate of audio data.

[0088] Please see Figure 7 , Figure 7 A flowchart illustrating a data interaction method according to an embodiment of this application is shown. This method is applied to the aforementioned first electronic device, which is used to interact with a second electronic device. The following will focus on... Figure 7 The process shown will be described in detail. The data interaction method may specifically include the following steps:

[0089] Step S410: Determine the first distance relationship between the first electronic device and the target human body and the first distance threshold, and determine the second distance relationship between the second electronic device and the target human body and the second distance threshold.

[0090] Step S420: Determine the positional relationship between the first electronic device and the second electronic device and the target human body.

[0091] For a detailed description of steps S410-S420, please refer to steps S110-S120, which will not be repeated here.

[0092] Step S430: If it is determined that the first distance is less than a distance threshold based on the first distance relationship, the second distance is less than the distance threshold based on the second distance relationship, and the first electronic device and the second electronic device are located on different sides of the target human body based on the position relationship, then the current data interaction mode is determined from multiple data interaction modes.

[0093] The electronic device can pre-set and store multiple data interaction modes, each with its own distinct data interaction method. For example, the multiple data interaction modes may include a first data interaction mode, a second data interaction mode, and a third data interaction mode, each with a different data interaction method. Optionally, the first data interaction mode may include a simplified mode, where devices do not need to interact or verify each other's data; the second data interaction mode may include a conventional one-way / two-way communication mode, which typically includes one master device (such as the first electronic device) and one or more slave devices (such as the second electronic device) for data communication in this scenario; the third data interaction mode may include a multi-device simultaneous communication mode, which typically includes two or more master devices (such as the first electronic device) communicating, with no limit on the number of slave devices (such as the second electronic device).

[0094] In this embodiment, when it is determined that the first distance is less than a distance threshold based on the first distance relationship, the second distance is less than a distance threshold based on the second distance relationship, and the first electronic device and the second electronic device are located on different sides of the target human body based on the position relationship, a data interaction mode can be determined as the current data interaction mode from multiple data interaction modes.

[0095] In some implementations, the first electronic device may determine the current data interaction mode from multiple data interaction modes by random selection; the first electronic device may determine the current data interaction mode from multiple data interaction modes by polling; the first electronic device may determine the current data interaction mode from multiple data interaction modes by user selection, etc., without limitation.

[0096] Step S440: Based on the current data interaction mode and the electric field human body communication technology, construct the data interaction channel and perform data interaction through the data interaction channel.

[0097] In this embodiment, when the current data interaction mode is determined from multiple data interaction modes, a data interaction channel between the first electronic device and the second electronic device can be constructed based on the current data interaction mode and the electric field human body communication technology, and data interaction between the first electronic device and the second electronic device can be carried out through the data interaction channel.

[0098] In some implementations, if the current data interaction mode is the first data interaction mode, a data interaction channel between the first electronic device and the second electronic device is constructed based on electric field human body communication technology. The first electronic device is controlled to work in the transmitting state so as to send the first data to the second electronic device working in the receiving state through the data interaction channel.

[0099] If the current data interaction mode is the first data interaction mode, then no pairing process or additional data interaction process is required between the first and second electronic devices, essentially achieving the user experience of a wired connection. This first data interaction mode can be used simultaneously for switching between multiple devices without requiring additional device pairing operations. Furthermore, this first data interaction mode can be applied to music-related applications. Since music-related data can tolerate a certain amount of packet loss during normal use, there is no need for secondary verification of received data integrity, thus allowing for direct and simple application.

[0100] As an implementable approach, in the first data interaction mode, the first data sent by the first electronic device may include a data frame header, data content, and others. The data frame header mainly includes the device information ID / address of the first device, the transmitted signal strength, the data type, and other custom data. The data content includes audio data transmission content, i.e., the specific data. Other information includes definition information such as CRC checksum, data source, and whether a response is required.

[0101] In some implementations, if the current data interaction mode is the second data interaction mode, the first electronic device is controlled to operate in the transmitting state and transmit broadcast frames at a preset period. After transmitting the broadcast frames, it switches from the transmitting state to the receiving state. If a response data is received from the second electronic device based on the monitored broadcast frames, a data interaction channel is established between the first and second electronic devices based on electric field human body communication technology, and data interaction is performed through the data interaction channel. It can be understood that in the second data interaction mode, the data interaction process between the first and second electronic devices is as follows: the first electronic device transmits a broadcast, the second electronic device responds and accesses, and the first and second electronic devices negotiate data transmission.

[0102] As an example, the first electronic device can transmit a broadcast frame that says "I am the master device 01, are there any other devices?" and the second electronic device can return response data that says "There are other devices, I am the slave device 01".

[0103] Optionally, the response data may include basic information of the second electronic device, device type, device purpose, device name ID, device signal quality, etc., which are not limited here.

[0104] As an feasible approach, if the master device does not receive response data from the second electronic device based on the monitored broadcast frame within a preset time period while transmitting broadcast frames according to a preset period, it can stop transmitting broadcast frames to save power consumption of the first electronic device.

[0105] As an feasible approach, if a data interaction channel is constructed between the first electronic device and the second electronic device based on electric field human body communication technology, the first electronic device and the second electronic device can normally send and receive data through the data interaction channel, that is, perform data interaction through the data interaction channel.

[0106] One method of data interaction via a data interaction channel includes: controlling a first electronic device to operate in a transmitting state to send second data to a second electronic device operating in a receiving state via the data interaction channel; and switching from the transmitting state to the receiving state after sending the second data. If feedback information is received from the second electronic device (which has switched from the receiving state to the transmitting state) based on the received second data, the device switches back from the receiving state to the transmitting state to send third data to the second electronic device (which has switched from the transmitting state to the receiving state) via the data interaction channel. It is understood that during this data interaction process, the second electronic device needs to respond to the data sent by the first electronic device; the requirement for a response can be carried within the data sent by the first electronic device.

[0107] Optionally, if no feedback information (acknowledgment) is received from the second electronic device during this process, the first electronic device may repeatedly send the second data until a timeout or number of times the communication is determined to be interrupted or the second electronic device is not present (e.g., the second electronic device is too far away from the body, the first device is too far away from the body, the second device has its data receiving function turned off, the second device is powered off, etc.).

[0108] One method of data interaction via a data interaction channel includes: controlling a first electronic device to operate in a transmitting state to send second data to a second electronic device operating in a receiving state via the data interaction channel; and switching from the transmitting state to the receiving state after sending the second data. Upon receiving the second data, the second device does not return any information and waits for the first electronic device to send the next data. It is understood that during this data interaction process, the second electronic device does not need to respond to the data sent by the first electronic device; the requirement for a response can be carried within the data sent by the first electronic device.

[0109] In some implementations, if the current data interaction mode is the third data interaction mode, the working state of the first electronic device can be detected. This working state includes being in a transmitting state or a receiving state. If it is determined that the first electronic device is in a transmitting state based on the working state, the working state of the second electronic device is determined to be a receiving state. The first electronic device is controlled to work in the transmitting state and transmit broadcast frames at a preset period. After transmitting the broadcast frames, it switches from working in the transmitting state to working in the receiving state. If the response data returned by the second electronic device based on the monitored broadcast frames is received, a data interaction channel between the first electronic device and the second electronic device is constructed based on electric field human body communication technology, and data interaction is performed through this data interaction channel.

[0110] Optionally, in the third data interaction mode, there can be multiple master devices (including the first electronic device), and multiple master devices need to compete for the data interaction channel formed by the target human body to send data. Therefore, in this embodiment, the first electronic device can detect its working status to determine whether it is in the sending state (i.e., successfully compete for the data interaction channel), and in the sending state, it can conduct subsequent data interaction with the second electronic device.

[0111] As an example, the first electronic device can transmit "I am the master device 01, are there any other devices?", and other master devices can return "I am the master device 02, device information is XXX".

[0112] Optionally, after the first electronic device finishes sending data, the channel is idle. In the idle state, other master devices can actively initiate communication processes.

[0113] As one feasible approach, the data sent by the first electronic device can be received by any other master device and second electronic device in a receiving state. The device ID can be specified when the data is sent, so only the device corresponding to the device ID will receive the data and respond, while other devices can remain silent.

[0114] The data interaction method provided in one embodiment of this application is compared to... Figure 4 The data interaction method shown in this embodiment further determines the current data interaction mode from multiple data interaction modes, and constructs a data interaction channel for data interaction based on the current data interaction mode and electric field human body communication technology, thereby adapting to different data interaction modes and improving the diversity of data interaction application scenarios.
