Description

Information processing method and related device and equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to an information processing method, and a related apparatus and device.

Background

The 'one-touch transmission' technology means that pairing is rapidly realized between two devices through simple 'touch-touch' operation, wireless connection is established, and then functions of efficient information mutual transmission and the like can be completed. Wherein the "bump-and-bump" operation to enable pairing mainly depends on the bluetooth identity of the device stored in the NFC tag of the device.

The 'one-touch transmission' implementation is commonly performed among devices which are configured with the NFC tag during production, and for devices which are not configured with the NFC tag, if a user wants to implement the 'one-touch transmission' function, the user is required to manually configure the NFC tag for the device. However, at present, the implementation process of manually configuring the NFC tag for the device is very complex (for example, steps of acquiring a bluetooth identifier of the device, converting the bluetooth identifier into a two-dimensional code form, burning the bluetooth identifier into a blank NFC tag through a professional burning application program, and the like), so that a non-professional person is difficult to perform. Therefore, how to simplify the configuration of the NFC tag and enable the "one-touch-transmission" technology to be universally implemented between devices is a technical problem to be solved at present.

Detailed Description

The terminology used in the following embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used in the specification of the present application and the appended claims, the singular forms "a", "an", "the" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the listed items.

First, terms and concepts related to the embodiments of the present application will be described.

(1) Near field communication

Near Field Communication (NFC) is integrated and evolved from a non-contact Radio Frequency Identification (RFID) and an interconnection technology, and an induction card reader, an induction card and a point-to-point function are combined on a single chip, so that identification and data exchange can be performed with compatible equipment in a short distance.

The short-distance interaction of the NFC greatly simplifies the whole authentication and identification process, so that the electronic devices can access each other more directly, safely and clearly. Through NFC, a plurality of devices such as computers, digital cameras, mobile phones and PDAs can be conveniently and rapidly connected in a wireless mode, and data exchange and service are achieved. For example, when an NFC chip is placed in a mobile phone, the mobile phone can realize electronic payment and read information of other NFC devices and tags.

NFC enabled devices may exchange data in an active communication mode or a passive communication mode. Next, a structure of an NFC communication system provided in an embodiment of the present application is described.

Referring to fig. 1A, an NFC communication system may include an initiator device and a target device. As shown in fig. 1A, the initiator generates a radio frequency field to initiate communication conforming to the corresponding protocol specification, the target device actively communicates, which means that both the initiator and the target device generate a magnetic field to transmit data, and the target device passively communicates, which means that the target device transmits data in a load modulation scheme, only the initiator generates the radio frequency field. In a passive state, the NFC initiator provides a radio frequency field in the whole communication process, and sends out the request data at an agreed transmission speed, the target device is in the radio frequency field, and after receiving the request data, the target device returns reply data corresponding to the request data at the same transmission speed by using the radio frequency field generated by the initiator. In a passive communication state, the target device can utilize the function to reduce energy consumption and prolong the service life of the device. The initiating device generally includes a processing unit, an RF module, a control unit, and an antenna. The initiating device may be a reader, a cell phone, etc. The target device may be a chip and antenna with certain computing and memory capabilities. The target device may be an NFC tag, a cell phone, etc. The initiating device and the target device adopt wireless transmission, the devices of the two parties can normally work only when being close to each other, and the two parties of communication mainly adopt an inductive coupling mode to transmit radio frequency signals.

(2) Bluetooth (R) device

Bluetooth is a radio technology that can support short-range communication between devices.

Please refer to fig. 1B, which is a flowchart illustrating a bluetooth connection establishment process according to an embodiment of the present disclosure. As shown in fig. 1B, before the slave device establishes a connection with the master device, the slave device needs to broadcast first, that is, the slave device opens the radio frequency module and continuously sends a broadcast signal to the outside, where t is a broadcast interval time; the method comprises the steps that the main device is in a scanning state, at the moment, the main device opens a radio frequency scanning window, and when a broadcast radio frequency channel and a main device scanning radio frequency channel are in the same channel, the main device scans a broadcast signal sent by the slave device; the master device sends a connection request to the slave device, the slave device responds to the master device after receiving the connection request, and the master device indicates that the Bluetooth connection is successfully established after receiving response information of the slave device aiming at the connection request.

(3) Bluetooth connection based on NFC

The Bluetooth technology based on NFC is to acquire a Bluetooth identifier for establishing Bluetooth connection through NFC communication, and then the Bluetooth identifier is quickly paired to establish the Bluetooth connection. If the electronic device A and the electronic device B are both Bluetooth devices with NFC functions, the electronic device A is close to the electronic device B, and the Bluetooth identification of the electronic device B is acquired in an NFC communication mode, so that Bluetooth pairing is completed with the electronic device B, and Bluetooth connection is achieved.

The embodiment of the application provides an information processing method, after terminal equipment (such as a computer, a television and the like) and accessories (such as a mouse, a remote controller and the like) with an NFC function are paired, the accessories record information such as a Bluetooth identifier of the terminal equipment on an NFC label of the terminal equipment, and electronic equipment can be connected with the terminal equipment by acquiring the information such as the Bluetooth identifier of the terminal equipment through approaching or touching the accessories, so that the functions of one touch transmission, multi-screen cooperation, data sharing and the like are realized.

The following first presents an architecture diagram of a system according to an embodiment of the present application.

Please refer to fig. 2, which is a block diagram illustrating an architecture of an information processing system according to an embodiment of the present disclosure. As shown in fig. 2, the information processing system may include a first electronic device 100, a second electronic device 200, and a third electronic device 300. Wherein:

the first electronic device 100 and the second electronic device 200 can establish a connection through the third electronic device 300, thereby implementing functions such as multi-screen cooperation, one touch transmission, and the like. The third electronic device 300 serves as an accessory of the first electronic device 100, such as a mouse serving as an accessory of a computer, a remote controller serving as an accessory of a television, and the like.

Specifically, the method comprises the following steps: first, the first electronic device 100 and the third electronic device 300 establish a connection, which may be a wireless connection (e.g., a bluetooth connection) or a wired connection (e.g., through a data line). Based on the connection, the third electronic device 300 acquires the first identifier of the first electronic device 100, where the first identifier includes the bluetooth address of the first electronic device 100, and stores the acquired first identifier in its own NFC tag. Then, the second electronic device 200 obtains the first identifier of the first electronic device 100 by approaching or touching the third electronic device 300.

After acquiring the first identifier of the first electronic device 100, the second electronic device 200 may send a connection request to the first electronic device 100, so as to establish a connection. In some embodiments, the first electronic device 100 establishes a bluetooth connection with the second electronic device 200. In some embodiments, in order to improve the information transmission quality, the first electronic device 100 and the second electronic device 200 may further establish a WLAN connection, a WiFi connection, and the like through a bluetooth connection.

After the first electronic device 100 and the second electronic device 200 are connected, the two devices can achieve functions of multi-screen cooperation, one touch transmission, information sharing, and the like.

In some embodiments, the second electronic device 200 may send a user-selected file (e.g., a file of the type picture, text, audio, video, etc.) to the first electronic device 100 based on the connection. Thus, as seen from the user, the file can be successfully transmitted by only bringing the second electronic device 200 close to or into contact with the third electronic device 300.

In some embodiments, second electronic device 200 may send its user interface to first electronic device 100 based on the connection, with first electronic device 100 displaying the user interface within its collaboration window. Then, the user may manipulate the application on the user interface on the collaboration window, and the first electronic device 100 sends manipulation information to the second electronic device 200 through the connection, so that the second electronic device 200 responds to the manipulation information and performs a corresponding operation. That is, the user can cooperatively operate the second electronic device 200 on the first electronic device 100. For example, the operation is performed on a collaboration window displayed by the first electronic device 100: if the "gallery" is opened and the "picture a" in the "gallery" is deleted, the same operation will be performed in the second electronic device 200: and opening the gallery and deleting the picture A in the gallery.

In some embodiments, the second electronic device 200 may transmit the content copied by the second electronic device to the first electronic device based on the connection. After receiving the content copied by the second electronic device, the first electronic device 100 may paste the content copied by the second electronic device on the currently displayed user interface. In this way, as seen from the user, the first electronic device 100 can automatically attach the content copied on the second electronic device by only bringing the second electronic device 200 close to or touching the third electronic device 300.

In some embodiments, the third electronic device 300 may store the identities of multiple devices in its NFC tag. As shown in fig. 2, the architecture diagram of the system may further include a fourth electronic device 400, the fourth electronic device 400 being an extended screen of the first electronic device 100.

In some embodiments, the third electronic device 300 may obtain the first identifier and the first indication information from the first electronic device 100, and further store a corresponding relationship between the first identifier and the first indication information in its NFC tag. The first indication information may be a bluetooth name of the first electronic device 100, or a device identifier of the first electronic device 100, or a first preset character, such as "0". The third electronic device 300 may acquire the second identifier and the second indication information from the fourth electronic device 400, so that the NFC tag stores the correspondence between the second identifier and the second indication information. Wherein the second identifier includes a bluetooth address of the fourth electronic device 400, and the second indication information may be a bluetooth name of the fourth electronic device 400, or a device identifier of the fourth electronic device 400, or a second preset character, such as "1".

In this embodiment, the third electronic device 300 is paired with the first electronic device 100. The first electronic device 100 may periodically detect the position where the focus of the third electronic device 300 is located. When detecting that the focus of the third electronic device 300 is on the display screen of the first electronic device, the first electronic device 100 sends first indication information to the third electronic device 300, the third electronic device 300 receives the first indication information, and responds to the first indication information based on the corresponding relationship between the stored first indication information and the first identifier, so as to transmit the first identifier in the NFC communication process; when it is detected that the focus of the third electronic device 300 is not on the display screen of the first electronic device 100, that is, the focus of the third electronic device 300 is located on the display screen of the fourth electronic device 400, the first electronic device 100 sends second indication information to the third electronic device 300, the third electronic device 300 receives the second indication information, responds to the second indication information based on the correspondence between the stored second indication information and the second identifier, and transmits the second identifier in the NFC communication process. For example, when the first indication information is "0", the second indication information is "1", and the third electronic device 300 receives "0", the first identifier is transmitted in the NFC communication process; when the third electronic device 300 receives "1", the second identifier is transmitted in the NFC communication process. The first indication information may also be a device identifier of the first electronic device 100, the second indication information may be a device identifier of the fourth electronic device 400, and when the third electronic device 300 receives the device identifier of the first electronic device 100, the first identifier may be transmitted in the NFC communication process based on the stored correspondence between the device identifier of the first electronic device 100 and the first identifier; when the third electronic device 300 receives the device identifier of the fourth electronic device 400, the second identifier may be transmitted in the NFC communication process based on the stored correspondence between the device identifier of the fourth electronic device 400 and the second identifier. For example, the first indication information may also be a bluetooth name of the first electronic device 100, and the second indication information may also be a bluetooth name of the fourth electronic device 400.

In some embodiments, when the first electronic device 100 detects that the focus of the third electronic device 300 is not on the display screen thereof and the duration is greater than the preset threshold, the first electronic device 100 sends the second indication information to the third electronic device 400. The preset threshold is not a fixed value, for example, the preset threshold is 1s, 3s, and the like.

In some embodiments, the fourth electronic device 400 may also periodically detect the location at which the focus of the third electronic device 300 is located. When the fourth electronic device 400 detects that the focus of the third electronic device 300 is on the display screen of the fourth electronic device 400, the fourth electronic device 400 may transmit first information that the third electronic device 300 is focused on the fourth electronic device 400 to the first electronic device 100. In response to the first information, the first electronic device 100 transmits second indication information to the third electronic device 300. Alternatively, when the fourth electronic device 400 detects that the focus of the third electronic device 300 is on the display screen of the fourth electronic device 400, the fourth electronic device 400 may directly transmit the second indication information to the third electronic device 300.

When the third electronic device 300 receives the first indication information, the third electronic device 100 transmits the first identifier in the NFC communication process. When the third electronic device 300 receives the second indication information, the third electronic device 300 transmits the second identifier in the NFC communication process.

For example, the third electronic device 300 may further store the first identifier when acquiring the first identifier of the first electronic device 100. When the second identifier of the fourth electronic device 400 is acquired, the third electronic device 300 may store the second identifier of the fourth electronic device 400.

When the second electronic device 200 approaches or touches the third electronic device 300, the identifier of the electronic device may be acquired through NFC communication, and a connection may be established with the electronic device corresponding to the identifier through the acquired identifier. That is, if the second electronic device 200 acquires the first identifier, the second electronic device 200 establishes a connection with the first electronic device 100; if the second electronic device 200 acquires the second identifier, the second electronic device 200 and the fourth electronic device 400 establish a connection. It should be noted that, if the second electronic device 200 and the first electronic device 100 have already established a connection before the second electronic device 200 acquires the first identifier of the first electronic device 100, after the second electronic device 200 acquires the first identifier, the second electronic device 200 does not need to establish a connection with the first electronic device 100 again.

In some embodiments, the first electronic device 100 may connect two or more electronic devices as an extended screen. When the third electronic device acquires the identifier of the electronic device, the corresponding relationship between the identifier of the electronic device and the indication information may be stored in the NFC tag. The indication information may be a bluetooth name of the electronic device, or a device identifier of the electronic device, or a preset character, etc. The example in which the first electronic device 100 can connect two or more electronic devices as the extended screen is similar to the example in which the first electronic device 100 connects the fourth electronic device 400 as the extended screen, and details thereof are not repeated here.

It should be understood that the first electronic device 100 and the fourth electronic device 400 are electronic devices having a bluetooth function, such as a notebook, a tablet, a smart tv, etc.; the second electronic device 200 is an electronic device having a bluetooth function and an NFC function, such as a mobile phone, a smart watch, and the like; the third electronic device 300 is an electronic device having an NFC function and a bluetooth function, such as a mouse, a remote controller, a stylus pen, a keyboard, a handle, and the like.

As shown in fig. 8, when a first connection is established between a first electronic device and a second electronic device, the first electronic device displays a window 801 through a display, where the window 801 specifically includes: a display area 8010, a "allow" control 8011, and a "reject" control 8012. The display area 8010 is configured to output first pairing information to a user, where the first pairing information is used to prompt the user to which electronic device the first electronic device is to be connected, and as shown in fig. 8, the pairing information is "whether to allow the second electronic device to connect to the computer (the first electronic device)". The second electronic device displays a window 802 through a display, where the window 802 specifically includes: a display area 8020, a "cancel" control 8021, and a "connect" control 8022. The display area 8020 is configured to output second pairing information to the user, where the second pairing information is used to prompt the user to which device the second electronic device is to be connected, as shown in fig. 8, and the second pairing information is "after connection, you can operate the mobile phone on the computer and share data between the devices. "

When the first electronic device acquires a user operation on the "allow" control 8011 and the second electronic device acquires a user operation on the "connect" control 8022, the first electronic device and the second electronic device establish connection for the first time. Otherwise, the first electronic device and the second electronic device fail to establish the second connection for the first time.

When the first electronic device and the second electronic device establish the second connection again, the second electronic device can establish the second connection with the first electronic device again by the method described in the steps S106-S108 only by touching the second electronic device to the third electronic device by the user to obtain the first identifier, and the first identifier includes the bluetooth address of the first electronic device, and the user does not need to confirm the first electronic device and the second electronic device again.

In some embodiments, the first data is a first user interface displayed by the second electronic device.

The icon of any application program included in the fixed application program column 923 can also be used to cause the second electronic device to launch an application corresponding to the icon in response to a user operation, such as a touch operation.

In some implementations, before step S106 (the second electronic device approaches or touches the third electronic device), the second electronic device receives a first operation, and the first operation is used to select the first data to be shared. When the second electronic device displays the interface 92, a first operation of the user is received, for example, the first operation may be: the user clicks the "multi-screen collaboration" control. The second electronic device determines the first data as an interface 92 (first user interface) currently displayed by the second electronic device.

As shown in fig. 9, the first electronic device displays a collaboration window 901, and displays an interface 91 through the collaboration window, where the displayed content of the interface 91 is the same as the first user interface.

In this implementation, it should be noted that before the second electronic device approaches or touches the third electronic device, in one case, the second connection established between the first electronic device and the second electronic device through step S108 is not disconnected, and then the second electronic device touches or approaches the third electronic device, and directly sends the first data (the first user interface) to the first electronic device without establishing the second connection with the first electronic device again; in another case, the second connection established between the first electronic device and the second electronic device is already disconnected (if the first electronic device and the second electronic device do not share information within a set time, and the first electronic device and the second electronic device automatically disconnect the established second connection), the second electronic device approaches or touches a third electronic device, a first identifier is obtained, the first identifier includes a bluetooth address of the first electronic device, the second electronic device and the first electronic device reestablish the second connection, and then the first data is sent to the first electronic device. For the implementation of establishing the second connection between the second electronic device and the first electronic device, reference may be made to the description in steps S106 to S108, and details are not described here again.

In some implementations, after step S108 (the second electronic device establishes the second connection with the first electronic device using the first identifier), the second electronic device receives a first operation of the user, and the first operation may be: the user clicks the "multi-screen collaboration" control. The second electronic device determines the first data as an interface 92 (first user interface) currently displayed by the second electronic device. Further, the second electronic device receives a second operation of the user, where the second operation may be an operation that the user may initiate a sharing task on the second electronic device, for example, clicking a "sharing" control. Furthermore, the second electronic device transmits the first data to the first electronic device based on the connection between the first electronic device and the second electronic device. As shown in fig. 9, the first electronic device displays a collaboration window 901, and displays an interface 91 through the collaboration window, where the displayed content of the interface 91 is the same as the first user interface.

In some embodiments, the first electronic device detects a target operation of sharing the target file with the first application program (e.g., a user drags an identifier of the target file stored in the first electronic device onto an icon of the first application program in the collaboration window, or a user's finger clicks a drag operation of a left mouse button on the identifier of the target file, and the target operation is finished when the user's finger leaves the left mouse button, or a user's finger presses a touch screen to drag the identifier of the target file, and the target operation is finished when the user's finger leaves the touch screen, and the target operation may be other types of user operations, which are not limited herein), and in response to the target operation, sends the target file and the identifier of the first application program to the second electronic device, so that the second electronic device searches for the first application program through the identifier of the first application program, and opening the target file through the first application program.

The format of the target file may be a text, picture, audio, video, link, etc. type file. The first application program may include social application programs (e.g., WeChat, QQ, microblog, etc.), editorial application programs (e.g., WPS, memo, etc.), audio and video application programs (e.g., Internet cloud music, QQ music, etc.), and the like.

When the first electronic device detects a target operation that acts on the logo of "picture 1" (which drags the logo of "picture 1" to the logo of "memo" in the collaboration window 1002 as shown in fig. 10A), the first electronic device transmits the logos of "picture 1" and "memo" to the second electronic device through the established second connection. After receiving the identifications of the "picture 1" and the "memo", the second electronic device finds the application program "memo" through the identification of the "memo", and further detects whether the "memo" can open the "picture 1", and since the "memo" can open the file in the picture format, the "picture 1" is opened by the "memo" and displayed on the second electronic device, as shown in fig. 10B, the second electronic device automatically creates a new note in the "memo", and displays the new note through a display screen, as shown in the fig. 31, the interface 31 includes: a return control 40, a previous operation control 41, a next operation control 42, a save control 43, a title area 44, a content display area 45, and an edit area 46 (including a list control, an edit control, a picture control, a voice control, a handwriting control, and the like). The second electronic device automatically inserts "picture 1" into the content display area 45. The user may continue to edit or save the note, e.g., when the second electronic device detects that the user clicks on the return control 40, the second electronic device may display the user interface that is previous to the current user interface; when the second electronic device detects that the user has clicked on the save control 43, the second electronic device can save the contents of the current title area 44 and the contents of the content display area 45. The second electronic device sends the interface 31 to the first electronic device, the first electronic device updates the interface 20 to be the interface 21, and the interface 21 includes the same content as the interface 31.

In one possible implementation, as shown in fig. 10C, the user may open a memo in the collaboration window 1002, as shown in the interface 22, the memo includes a plurality of notes, and the user drags the identification of the file "picture 1" to a designated note (here, "note 1 xxxxx") by a target operation and releases the target operation. The first electronic device may send the "picture 1", the identifier of the memo and the identifier of the designated note to the second electronic device, and the second electronic device finds the memo on the second electronic device through the identifier of the memo and the identifier of the designated note, opens the designated note in the memo, and inserts the "picture 1" into the designated note, as shown in an interface 31 in fig. 10D. The second electronic device sends the interface 31 to the first electronic device, so that the interface displayed by the collaboration window 1002 is updated to the interface 23 by the interface 22, and the first electronic device opens "picture 1" in the memo specified by the note "note 1 xxxxx" through the collaboration window 1002.

Example (b):

please refer to fig. 13, which is a flowchart illustrating another information processing method according to an embodiment of the present application. The information processing method may be collectively executed by the respective electronic devices in the architecture diagram of the system shown in fig. 2 described above. As shown in fig. 13, the information processing method may include some or all of the following steps.

S402: the first electronic device and the third electronic device establish a first connection.

The specific implementation of step S402 can refer to step S102 described above, and is not described here again.

S404: and the fourth electronic equipment establishes a third connection with the third electronic equipment.

The implementation of step S404 is similar to that of step S202, and is not described here again.

S406: the third electronic device obtains a first identifier and first indication information of the first electronic device through the first connection, wherein the first indication information comprises one or more of a device identifier, a Bluetooth name and a first preset character of the first electronic device.

S408: the third electronic device stores the corresponding relation between the first identification and the first indication information.

In some possible implementations, the third electronic device may obtain a correspondence between the first identifier and the first indication information, and store the correspondence between the first identifier and the first indication information in the NFC tag.

S410: and the third electronic equipment acquires a second identifier and second indication information of the fourth electronic equipment through a third connection, wherein the second identifier comprises a Bluetooth address of the fourth electronic equipment, and the second indication information comprises one or more of an equipment identifier, a Bluetooth name and a second preset character of the fourth electronic equipment.

S412: the third electronic device stores the corresponding relation between the second identification and the second indication information.

In some possible implementations, the third electronic device may obtain a correspondence between the second identifier and the second indication information, and store the correspondence between the second identifier and the second indication information in the NFC tag.

It should be understood that, in the information processing method, since the NFC tag is used to store the corresponding relationship between the first identifier and the first indication information and the corresponding relationship between the second identifier and the second indication information, the storage space of the NFC tag can store at least two corresponding relationships between the identifiers and the indication information.

In the foregoing step S408 and step S412, the third electronic device stores the corresponding relationship between the first identifier and the first indication information, and the corresponding relationship between the second identifier and the second indication information in the NFC tag, in a possible implementation manner: the first connection is established between the first electronic device and the third electronic device, the third electronic device acquires the first identifier and the first indication information, and then the third electronic device stores the corresponding relation between the first identifier and the first indication information into the NFC label when the third electronic device detects that the current remaining storage space of the NFC label is larger than a first threshold value and the corresponding relation between the first identifier and the first indication information does not exist in the NFC label. Otherwise, the third electronic device outputs prompt information of writing failure of the NFC label.

It should be understood that the first threshold is not a fixed value, and the setting of the first threshold is related to the size of the space for storing the identification and indication information in practical application.

It should be understood that the implementation manner of writing the corresponding relationship between the second identifier and the second indication information into the NFC tag is similar to that of writing the corresponding relationship between the first identifier and the first indication information into the NFC tag, and is not described herein again.

It should be understood that, the implementation manner of writing the first identifier and the first indication information, and the second identifier and the second indication information into the NFC tag in the foregoing embodiment is not limited, and other implementation manners may also be included, and are not limited herein.

S414: when the first electronic device determines that the focus of the third electronic device is on the first electronic device, the first electronic device sends first indication information to the third electronic device; or, when the first electronic device determines that the focus of the third electronic device is not on the first electronic device, the first electronic device sends the second indication information to the third electronic device.

Please refer to fig. 14, which is a schematic diagram illustrating an embodiment of an information processing method according to the present application. Preferably, the first electronic device is a computer, and the fourth electronic device is a tablet. As shown in fig. 14, in some implementations, the first electronic device and the fourth electronic device may be brought online by third party software (e.g., "XDisplay") and a data line 161. Furthermore, the user can perform "Window + p" switching to "extended" mode on the first electronic device, so that the fourth electronic device serves as an extended screen of the first electronic device. The first identifier and the first indication information, the second identifier and the second indication information may be written into the NFC tag of the third electronic device by the method described in the above steps S402-S412. Preferably, the third electronic device is a mouse having an NFC function and a bluetooth function.

In one possible implementation, the pairing of the third electronic device and the first electronic device is completed. The first electronic device may periodically detect a location of a focus of the third electronic device. When the focus of the three electronic devices is detected to be on a display screen of the first electronic device, the first electronic device sends first indication information to the third electronic device, the third electronic device receives the first indication information, and the first indication information is responded based on the corresponding relation between the stored first indication information and the first identification, and the first identification is transmitted in the NFC communication process; when the fact that the focus of the third electronic device is not located on the display screen of the first electronic device is detected, namely the focus of the third electronic device is located on the display screen of the fourth electronic device, the first electronic device sends second indication information to the third electronic device, the third electronic device receives the second indication information, the second indication information is responded based on the corresponding relation between the stored second indication information and the second identification, and the second identification is transmitted in the NFC communication process. For example, when the first indication information is "0", the second indication information is "1", and the third electronic device receives "0", the first identifier is transmitted in the NFC communication process; and when the third electronic equipment receives the '1', transmitting the second identifier in the NFC communication process. The first indication information may also be a device identifier of the first electronic device, the second indication information may be a device identifier of the fourth electronic device, and when the third electronic device receives the device identifier of the first electronic device, the first identifier may be transmitted in the NFC communication process based on the stored correspondence between the device identifier of the first electronic device and the first identifier; when the third electronic device receives the device identifier of the fourth electronic device, the second identifier may be transmitted in the NFC communication process based on the stored correspondence between the device identifier of the fourth electronic device and the second identifier. For example, the first indication information may also be a bluetooth name of the first electronic device, and the second indication information may also be a bluetooth name of the fourth electronic device.

In some embodiments, when the first electronic device detects that the focus of the third electronic device is not on the display screen of the first electronic device and the duration of the focus is greater than a preset threshold, the first electronic device sends second indication information to the third electronic device. The preset threshold is not a fixed value, for example, the preset threshold is 1s, 3s, and the like.

In some embodiments, the fourth electronic device may also periodically detect the location at which the focus of the third electronic device is located. When the fourth electronic device detects that the focus of the third electronic device is on the display screen of the fourth electronic device, the fourth electronic device may send first information that the third electronic device focuses on the fourth electronic device to the first electronic device. In response to the first information, the first electronic device sends second indication information to the third electronic device. Alternatively, when the fourth electronic device detects that the focus of the third electronic device is on the display screen of the fourth electronic device, the fourth electronic device may directly send the second indication information to the third electronic device.

And when the third electronic equipment receives the first indication information, the third electronic equipment transmits the first identifier in the NFC communication process. And when the third electronic equipment receives the second indication information, the third electronic equipment transmits a second identifier in the NFC communication process.

In some embodiments, the first electronic device 100 may connect two or more electronic devices as an extended screen. When the third electronic device acquires the identifier of the electronic device, the corresponding relationship between the identifier of the electronic device and the indication information may be stored in the NFC tag. The indication information may be a bluetooth name of the electronic device, or a device identifier of the electronic device, or a preset character, etc. The example that the first electronic device 100 can be connected to two or more electronic devices as the extended screen is similar to the example that the first electronic device 100 is connected to the fourth electronic device 400 as the extended screen, and the description thereof is omitted here.

In the information processing method, on which electronic device the focus of the third electronic device appears, the second electronic device can establish connection with the electronic device. If the focus of the third electronic equipment is on the first electronic equipment, the second electronic equipment establishes connection with the first electronic equipment; when the focus of the third electronic device is on the fourth electronic device, the second electronic device establishes connection with the fourth electronic device. By implementing the method, the user only needs to simply operate, the second electronic equipment can be switched between the plurality of electronic equipment to establish connection, interconnection and intercommunication between the second electronic equipment and the plurality of electronic equipment are realized, and information sharing and interaction are more convenient and faster.
