[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] The embodiments of this application can be applied to electronic devices. This application does not limit the product form of the electronic device, which may include but is not limited to smartphones, tablets, wearable devices, personal computers (PCs), netbooks, etc., and can be selected according to application requirements.

[0042] Figure 1 This is a flowchart of a device connection method disclosed in an embodiment of this application. Figure 1 The method shown is applied to a first device; in this application, the first device can be understood as a device that assumes the role of a master device in a wireless ad hoc network containing at least two devices. See also Figure 1 As shown, the device connection method may include:

[0043] Step 101: In response to the first sensor detecting a first device interconnection trigger operation, the first device sends a broadcast message, the broadcast message carrying first feature data, the first feature data being determined using the first sensor data.

[0044] In this embodiment, the device interconnection function is activated by a first device interconnection triggering operation, which is determined by a first sensor on the first device. After the first sensor detects the first device interconnection triggering operation, first feature data can be generated based on the first sensor data. The first device interconnection triggering operation is not fixed; it can be tapping the first device (within the detection range of the first sensor) two or three times, swiping the palm to the left, swiping the palm to the right, etc. The first sensor can be an existing sensor on the first device; that is, this application does not require a dedicated sensor and can reuse conventionally configured sensors in electronic devices. The first sensor can be any of the following: an ALS (Ambient Light Sensor), an image sensor, a TOF (Time-of-Flight) sensor, or any sensor capable of detecting hand gestures.

[0045] The first feature data is a "connection code" for interconnection between different devices. That is, when different devices (second devices) determine that the first feature data matches the feature data they generate after activating the device interconnection function, they will confirm that the first device is the interconnection object they need to connect to to realize a wireless self-organizing network.

[0046] In practical applications, the system has a pre-set mapping relationship between the first device interconnection trigger operation and the device interconnection function, and also has pre-set characteristics of the sensor data corresponding to the first device interconnection trigger operation. Therefore, when the user performs the first device interconnection trigger operation near the first sensor of the first device, the system detects sensor data that matches the characteristics corresponding to the first device interconnection trigger operation and determines to start the device interconnection function.

[0047] After confirming the activation of the device interconnection function, the first device, acting as the master device, sends a broadcast message carrying first characteristic data, waiting for the second device that needs to interconnect with it to listen to the broadcast message and send a connection request to it.

[0048] Step 102: Receive a connection request sent by the second device and establish a communication connection with the second device. The connection request is a request sent by the second device to the first device after successfully verifying the first feature data after detecting the second device interconnection trigger operation based on the second sensor. The verification of the first feature data includes matching the second feature data determined based on the second sensor data with the first feature data.

[0049] When the device interconnection function is activated, the second device can listen for broadcast messages in the environment. If a broadcast message is detected and the first feature data carried in it is verified, the second device will determine that the first device is the target device it needs to connect to. Based on the relevant data of the first device identifier carried in the broadcast message, the second device will send a connection request to the first device. After the first device receives the connection request and agrees, the first device and the second device will establish a communication connection.

[0050] It should be noted that the second device also needs to receive a trigger operation to start the device interconnection function. This is referred to as the second device interconnection trigger operation in this article. After the second sensor of the second device detects the second device interconnection trigger operation, it will also determine a second feature data based on the second sensor data and verify whether the first feature data and the second feature data match. Only if they match will a connection request be sent to the first device. If the match fails, the received broadcast message will not be responded to.

[0051] For example, a user taps three times on a laptop (first device) and then taps three times on a mobile phone (second device). After detecting the "three taps" action, the laptop activates the device interconnection function, synchronously generating first feature data and broadcasting a message. After detecting the "three taps" action, the mobile phone activates the device interconnection function, synchronously generating second feature data. If it hears the broadcast message from the laptop, it will also match and verify the first feature data in the broadcast data with its own generated second feature data. If the verification determines that the two feature data are the same or similar, the mobile phone will determine that it needs to establish a connection with the laptop, and therefore sends a connection request to the laptop. After receiving the connection request from the mobile phone, the laptop agrees to the request and establishes a connection with the mobile phone.

[0052] Figure 2 The timing diagram for establishing a connection between the first device and the second device disclosed in the embodiments of this application can be combined with... Figure 2 Understand the implementation of the solution in this application. The connection between the first device and the second device can be established based on Wi-Fi Direct technology, also known as Wi-Fi Direct connection technology.

[0053] In the implementation of the device connection method described in this embodiment, the user does not need to perform registration or login operations, and the user does not need to participate in connection verification during the connection establishment process between the two devices. The user only needs to perform a simple gesture operation on the first device and / or the second device. The whole implementation process is simple and efficient, and can meet the user's need for rapid interconnection in various scenarios.

[0054] In one implementation, the device connection method may include other content besides the steps described in the aforementioned embodiments, which involves the processing and determination of device roles. Figure 3For the device role processing flow disclosed in the embodiments of this application, please refer to [link / reference]. Figure 3 The device connection method may further include:

[0055] Step 301: If no connection request is received within the first time period after the broadcast message is sent, stop sending the broadcast message, and within the second time period after stopping sending the broadcast message, listen for broadcast messages from the second device only as the second device, and proceed to step 302 or step 303.

[0056] As those skilled in the art know, in the process of establishing an interconnection between devices, there are master devices and slave devices (or secondary devices), and the functions of different device roles differ. Master devices and slave devices differ in terms of control, resource performance, and communication modes. Generally speaking, the master device has bus control, actively initiates communication requests and dominates the data transmission process, usually has strong processing capabilities, can actively initiate communication requests, and obtain control through the bus arbitration mechanism. Slave devices usually passively respond to the requests of the master device and complete data transmission or specific operations according to instructions. In the embodiments of this application, the first device role can be understood as the master device, and the second device role can be understood as the slave device.

[0057] It is understandable that the device interconnection triggering operation on the first device side and the second device side can be the same, that is, the first device interconnection triggering operation and the second device interconnection triggering operation are the same, such as "tap three times" in the previous example. After the device confirms that it has received the device interconnection triggering operation, it will send a broadcast message as the first device by default, and can listen for broadcast messages sent by other devices as the second device.

[0058] If no connection request is received within the first time period after the broadcast message is sent, a device role conflict may occur. This means that because both the first and second devices are broadcasting and listening simultaneously, signal disturbances may occur, preventing either device from recognizing or listening to the other's broadcast message. Therefore, to avoid this conflict, a backoff algorithm can be used. Specifically, if the first device does not receive a connection request within the first time period after the broadcast message, it closes its first device role (i.e., master device role), stops sending broadcast messages, and for the second time period after stopping broadcast messages, it listens only for broadcast messages from the second device (i.e., slave device role).

[0059] The second duration is the sum of a base time and a random value. The first duration and the base time can be several seconds, and their specific values ​​are not fixed. Since neither the first nor the second device receives a connection request within the first duration, they will both switch to the second device role, only listening for broadcast requests from other devices. To prevent both devices from switching to the second device role simultaneously and for the same duration, thus preventing the interconnection operation from being completed, the second duration for each device is the sum of a base time and a random value. Because the second duration contains a random value, the second duration of the first and second devices will generally not be the same. This ensures that the times when the two devices start broadcasting again after the second duration will be staggered, guaranteeing that only one device broadcasts a message during a given period, while the other device only listens, allowing the other device to receive the broadcast message.

[0060] Step 302: If a broadcast message from the second device is detected within the second time period, send a connection request to the second device in the role of the second device.

[0061] If the first device detects a broadcast message from the second device within the second time period, it will act as a slave device and send a connection request to the first device after verifying the second feature data carried in the broadcast message based on the first feature data.

[0062] Step 303: If no broadcast message from the second device is detected within the second time period, restart the broadcast message as the first device.

[0063] If the first device does not receive a broadcast message from the second device within the second time period, it will resume its role as the first device, i.e., the master device, and start broadcasting messages again, while waiting for connection requests from other devices.

[0064] The solution described in this embodiment can avoid the problem of the first device and the second device being triggered to enable the device interconnection function at the same time. Due to the role conflict problem that may exist due to the simultaneous broadcasting and listening of devices, the solution implements role avoidance processing so that only one device broadcasts at a certain time, and the other device can listen to the broadcast message, thereby realizing the interconnection of the two devices.

[0065] In one implementation, the first device interconnection trigger operation includes M setting actions, and the second device interconnection trigger operation includes N setting actions, where M and N are both positive integers not less than 2, and M and N are different.

[0066] The previous embodiments described the same implementation of the first device interconnection trigger operation and the second device interconnection trigger operation. This embodiment, however, describes a different implementation of the first and second device interconnection trigger operations. The set action can be a tapping action on the device (or sensor area). Both the first and second device interconnection trigger operations can be tapping actions, but the number of taps differs. For example, the first device interconnection trigger operation involves two consecutive taps, while the second device interconnection trigger operation involves three consecutive taps.

[0067] In the implementation, different device roles can be pre-configured for different tap counts. For example, M taps indicate that the current device is enabling the device interconnection function as the first device, and N taps indicate that the current device is enabling the device interconnection function as a slave device. When the first sensor detects M taps, the first device, as the master device, generates first feature data and sends a broadcast message. When the second sensor detects N taps, the second device, as the slave device, generates second feature data and listens for broadcast messages from other devices.

[0068] In other implementations, the first device interconnection operation and the second device interconnection trigger operation contain the same number of set actions, but may have different directions. Therefore, the first device interconnection operation includes set actions in a first direction, and the second device interconnection trigger operation includes set actions in a second direction, with the first and second directions being opposite or opposite. For example, the first device interconnection operation is a hand swipe from left to right, and the second device interconnection operation is a hand swipe from right to left. Alternatively, the implementation can be pre-configured so that the set actions in the first direction correspond to the master device role, and the set actions in the second direction correspond to the slave device role.

[0069] Of course, in practical applications, there are also scenarios where multiple devices need to be interconnected. Therefore, receiving connection requests sent by the second device in the aforementioned embodiments may include: receiving multiple connection requests sent by multiple second devices; and establishing communication connections between the first device and the multiple second devices acting as the second device, respectively, based on the multiple connection requests.

[0070] In scenarios where multiple devices need to be interconnected, it is necessary to determine which device is the master device. When triggering device interconnection, the corresponding master device triggering operation can be performed on the device that needs to act as the master device. For example, if a hand moves from left to right, this device (corresponding to the first device) will start sending broadcast messages. In addition, the corresponding slave device triggering operation needs to be performed on the other interconnected devices. For example, if a hand moves from right to left, these devices (corresponding to the second devices) will start listening for broadcast messages. After listening to the broadcast message of the first device, each second device verifies the first feature data. If the verification confirms that the broadcast message was sent by the master device (first device), it will send a connection request to that device. The first device receives the connection requests from each second device in turn and establishes connections with each second device in the order in which the connection requests are received.

[0071] Based on the above implementation scheme, in scenarios that require interconnection of multiple devices, it can quickly and conveniently realize one-to-many (one master device and multiple slave devices) device interconnection without the need for the master device and multiple devices to scan and identify separately. Only a gesture action needs to be performed on each device, making the interconnection process efficient and easy to operate.

[0072] In one implementation, the first sensor can be a light sensor, such as an ALS sensor, which can detect changes in nearby light. Correspondingly, the first feature data obtained based on the first sensor data can characterize the light change waveform. In applications, the waveform can be processed and filtered to monitor whether it conforms to a set pattern, such as whether it exhibits three identical darkening patterns (when the sensor is blocked by a hand). If it does, the waveform is identified as the user's action of tapping three times.

[0073] The second sensor on the second device side can also be a light sensor, which will also detect light change data. The second feature data obtained based on the second sensor data can characterize the light change waveform. The verification of the first feature data by the second device includes determining whether the light change waveform characterized by the first feature data is the same as the light change waveform characterized by the second feature data.

[0074] In other implementations, the first sensor and the second sensor can be different types of sensors. The first sensor is used to obtain the user's gestures through a first sensing technology, and the second sensor is used to obtain the user's gestures through a second sensing technology. The working principles of the first sensing technology and the second sensing technology for detecting gestures are different.

[0075] For example, when the first device is in normal working condition, its image sensor can detect and collect the user's gestures, that is, collect the first device interconnection trigger operation; when the second device is in low power mode, its image sensor is in sleep or standby mode, and it can collect the user's gestures through the TOF sensor, that is, collect the second device interconnection trigger operation.

[0076] In this implementation, device interconnection trigger operations can be detected by different types of sensors on different devices, as long as there are sensors on the device that can detect the set trigger operation. This further expands the application scenarios and scope of the solution, meeting the device interconnection needs in multiple scenarios.

[0077] Figure 4 This is a flowchart of another device connection method disclosed in an embodiment of this application. Figure 4 The method shown is applied to the second device, see [link / reference]. Figure 4 As shown, the device connection method applied to the second device may include:

[0078] Step 401: In response to the second sensor detecting a second device interconnection trigger operation, determine second feature data based on the second sensor data.

[0079] In this text, the second device is a slave device in the interconnected devices. When a user wants to interconnect the devices, in addition to inputting a first device interconnection trigger operation on the first device side, a second device interconnection trigger operation is also input on the second device side. The second sensor on the second device detects the second device interconnection trigger operation and then determines the second feature data based on the second sensor data. The second sensor can be a light sensor, image sensor, TOF sensor, or other sensor capable of detecting gestures. The second sensor data is sensor data that can characterize the features of specific gestures, such as light change waveforms, light spatial position variation characteristics, target object posture, and target object movement patterns.

[0080] Step 402: Receive a broadcast message sent by the first device, the broadcast message carrying first feature data, the first feature data being determined using first sensor data.

[0081] After detecting the interconnection trigger operation, the second device can broadcast messages as a master device and / or listen to broadcast messages as a slave device. In this embodiment, the second device, as a slave device, can listen to the broadcast messages sent by the first device and parse them to obtain the first feature data carried therein.

[0082] Step 403: Verify whether the first feature data and the second feature data match.

[0083] After obtaining the first feature data and the second feature data, the second device will control the matching verification of the two. The matching verification is used to determine whether the first feature data and the second feature data are the same or correspond to each other, that is, to determine whether the device interconnection trigger operations received by the two devices are the same or correspond to each other.

[0084] Step 404: If a match is found, send a connection request to the first device.

[0085] If the verification confirms that the first characteristic data and the second characteristic data are the same or correspond, then the first device is determined to be the device requiring interconnection. Based on the first device identifier in the broadcast message, a connection request is sent to the second device. Upon receiving the connection request from the second device, the first device agrees to the request, thus establishing a communication connection with the second device. After a successful connection, the first and second devices can perform network transmission functions.

[0086] In the implementation of the device connection method described in this embodiment, the user does not need to perform registration or login operations, and the user does not need to participate in connection verification during the connection establishment process between the two devices. The user only needs to perform a simple gesture operation on the first device and / or the second device. The whole implementation process is simple and efficient, and can meet the user's need for rapid interconnection in various scenarios.

[0087] In one implementation, the first feature data includes a timestamp, which represents the time when the broadcast message was generated. The verification of whether the first feature data and the second feature data match includes: determining whether the first feature data and the second feature data meet a matching condition; determining whether the time difference between the time indicated by the timestamp and the current time exceeds a set time; if the first feature data and the second feature data meet the matching condition and the time difference does not exceed the set time, the verification is deemed successful.

[0088] In this implementation, in addition to verifying the feature data, it is also necessary to verify the time difference between the timestamp and the current time. This is because when a user performs a device interconnection operation, the devices to be interconnected typically receive the trigger operation sequentially, with minimal time intervals. Therefore, this implementation only verifies and matches broadcast messages within a set time frame. For example, when a second device detects a Wi-Fi Direct device (i.e., after detecting a broadcast message sent by the first device), it can verify the device's first feature data. Devices matching the feature data and whose broadcast time differs from the current time by less than 15 seconds are identified as potential connection devices, request a connection, and wait for the connection to complete. This implementation avoids interference from expired broadcast messages in the current device interconnection process.

[0089] In other implementations, the first device interconnection trigger operation may be the same as or different from the second device interconnection trigger operation. If the first device interconnection trigger operation is the same as the second device interconnection trigger operation, both the first device and the second device send broadcast messages and listen for the presence of devices to be connected, such as the device interconnection trigger operation of both the first device and the second device being "tap the device three times". If the first device interconnection trigger operation is different from the second device interconnection trigger operation, the first device sends broadcast messages and listens for the presence of devices to be connected, while the second device only listens for the presence of devices to be connected, such as the first device interconnection trigger operation of the first device being "tap the device twice", and the second device interconnection trigger operation of the second device being "tap the device three times".

[0090] For the foregoing method embodiments, in order to simplify the description, they are all described as a series of actions. However, those skilled in the art should understand that this application is not limited to the described order of actions, because according to this application, some steps can be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily essential to this application.

[0091] The methods described in the above-disclosed embodiments of this application are detailed in terms of their specific implementation methods. These methods can be implemented using various types of devices. Therefore, this application also discloses a device, and specific embodiments are given below for detailed explanation.

[0094] A connection control module is used to receive a connection request sent by a second device and establish a communication connection with the second device. The connection request is a request sent by the second device to the first device after successfully verifying the first feature data following the detection of the second device interconnection trigger operation based on the second sensor. The verification of the first feature data includes matching the second feature data determined based on the second sensor data with the first feature data.

[0095] This application also discloses a device connection apparatus, applied to a second device, which may include:

[0100] In the device interconnection implementation of the above-mentioned device connection device, the user does not need to perform operations such as registration and login, and the user does not need to participate in connection verification during the connection establishment process between the two devices. The user only needs to perform a simple gesture operation on the first device and / or the second device.

[0108] Specifically, if the electronic device is a device with the role of a second device, it executes program instructions to achieve the following:
