In S11, a first interface of a second terminal is projected on a display screen of the first terminal.
In S12, detection is performed on a first operation acting on the first interface.
In S13, in response to the first operation on the first object in the first interface being detected, the first operation on the first object is responded in the first terminal.
In these embodiments of the present disclosure, the first terminal may be a notebook computer, a tablet computer, a television terminal, or the like.
In some embodiments, the first terminal may be a terminal device with a screen larger than that of the second terminal. For example, when the first terminal is a personal computer (PC), the second terminal may be a mobile phone or a tablet computer. In some other embodiments, when the first terminal is a tablet computer or a tablet/PC two-in-one computer, the second terminal may be a mobile phone or a wearable device.
In these embodiments of the present disclosure, a wired connection may be established between the first terminal and the second terminal. The wired connection may include but is not limited to a universal serial bus (USB) connection or a serial port connection. In addition, a wireless connection may also be performed between the first terminal and the second terminal. For example, a wireless connection may be established through Bluetooth communication or near field communication (NFC). The wireless connection may also include a device to device (D2D) wireless connection, a wireless fidelity (Wi-Fi) direct connection, and the like.
For the wireless connection, In some embodiments:
the first terminal may send first broadcast information, and the first broadcast information may carry user account information of the first terminal;
a first connection request fed back by the second terminal based on the user account information may be received; and
a connection with the second terminal may be established according to the first connection request.
In this connection mode, the first broadcast information sent by the first terminal may carry user account information of the first terminal, and the user account information may include, for example, an account name of a user. After receiving the first broadcast information, the second terminal in the same local area network may display the user account information included in the first broadcast information on a display screen of the second terminal. The second terminal may receive a connection confirmation instruction sent by the user based on the user account information and send a first connection request to the first terminal. The first terminal may establish a connection with the second terminal according to the first connection request.
In this connection mode, the first terminal may broadcast a connection signal to establish a direct connection between the first terminal and the second terminal without need of transit through a router, thus reducing information leakage caused by the router transit, and improving the safety of interaction between the first terminal and the second terminal.
For the wireless connection, in some embodiments:
a QR code including login link information is displayed on a display screen of the first terminal;
a second connection request fed back by the second terminal based on the QR code is received; and
a connection with the second terminal is established according to the second connection request.
In this connection mode, the login link information may include device identification information of the first terminal. The second terminal may scan the QR code to parse and obtain the device identification information of the first terminal, and send a second connection request to the first terminal based on the device identification information. The first terminal may establish a connection with the second terminal based on the second connection request. The device identification information may be, for example, a physical address (media access control (MAC) address) of the device.
It is to be noted that in these embodiments of the present disclosure, after the connection is established by code-scanning login for the first time, the second terminal may also upload its own user account information to the first terminal, so that the first terminal may save the user account information. The user account information may include an account name of a user, and may also include a password that matches the account name of the user. Generally, when the second terminal and the first terminal belong to the same user, the second terminal may upload user account information to the first terminal based on the user's permission.
As shown in
When the connection is subsequently established, the first terminal may send second broadcast information. The second broadcast information may carry the MAC address of the first terminal and stored user account information of the second terminal. When the second terminal that receives the second broadcast information determines that the user account information carried in the second broadcast information is consistent with its own user account information, a connection with the first terminal can be established automatically through the MAC address of the first terminal in the second broadcast information. It can be understood that automatic connection establishment based on user account information brings convenience to the screen projection of the first terminal and the second terminal, and a user is not required to manually operate during each screen projection to achieve the connection, thereby improving the use experience.
Based on the connection established with the second terminal, the first terminal may project a first interface of the second terminal on the display screen based on operation S11. It is to be noted that the first interface of the second terminal may be a desktop of the first terminal, a setting interface of the second terminal, or an application interface of an application presently being displayed by the second terminal, which is not limited in these embodiments of the present disclosure. In addition, the layout of the first interface displayed on the display screen of the first terminal may be consistent with the layout in the second terminal.
In some embodiments, the size of the first interface displayed on the display screen of the first terminal may be the same as the size of the second terminal. In some other embodiments, the size of the first interface displayed on the display screen of the first terminal may be scaled appropriately according to the size of the display screen of the first terminal, but the aspect ratio consistent with the display screen of the second terminal may be maintained to reduce the strangeness of a user caused by the change in proportion, thereby improving the use experience.
The first terminal may detect a first operation acting on the first interface in operation S12 based on the displayed first interface of the second terminal. When the second terminal is a device that may be connected to a mouse and a keyboard, such as a notebook computer, the first operation may be a mouse-based click operation or a keyboard-based input operation, or the first operation may also be a voice-based voice control operation, which is not limited in these embodiments of the present disclosure.
In S13, when the first terminal detects the first operation on a first object in the first interface, the first operation on the first object is responded in the first terminal, that is, the second terminal can be controlled in the first terminal.
In these embodiments, the first object may be an icon of an application program on the desktop, a file in an application interface, or a control in a setting interface, which is not limited in these embodiments of the present disclosure.
It can be understood that in these embodiments, a first terminal can receive the sharing of a second terminal, and the second terminal can be controlled. An interactive user operation between the first terminal and the second terminal is simplified, and it is favorable for selecting the first terminal and/or the second terminal which are/is more suitable for a present application scenario based on an operation input by a user to perform corresponding operations, thereby improving the user experience and improving the intelligence of multi-screen interaction. In addition, for example, the first terminal is a computer, and the second terminal is a mobile phone. The shared content may be displayed on a display screen of the computer. Since the display screen is larger than the mobile phone, the visual experience of a user can be improved. In addition, the user-based first operation may be responded in the computer, and the hardware processing capacity in the computer is typically better than that of the mobile phone. Therefore, the response speed of the first operation can be increased, thereby improving the use experience.
In some embodiments, operation S13 includes that:
In response to the first operation of dragging the first object in the first interface out of the first interface being detected, the first object is stored in the first terminal.
In these embodiments, for example, the first interface may be an interface of an audio file list in a mobile phone or a smart speaker with a display screen, and the first object may be one of audio files. For another example, the first interface may be an interface of a picture file list in the mobile phone, and the first object may be an image file.
In these embodiments of the present disclosure, when the first terminal detects the first operation of dragging the first object in the first interface out of the first interface, the second terminal may send the first object to the first terminal, so that the first terminal can store the first object locally. For example, the first operation may be click dragging based on a mouse connected to a computer, or touch dragging of a user on a tablet computer.
It can be understood that in these embodiments, the first terminal may store the first object locally by detecting the first operation of dragging the first object in the first interface out of the first interface, thereby realizing the function of transmitting files from the second terminal to the first terminal. The file transmission function can be completed only by the first terminal detecting the first operation on the display screen of the first terminal, which reduces the number of terminals operated by a user and the number of operations of the user. Moreover, the operation is a simple dragging operation without an additional memory operation of the user, so it has the characteristics of a friendly interaction.
In some embodiments, the display screen may further include one or more second objects displayed outside the first interface.
The screen projection method applied to a first terminal may further include that:
detection is performed on a second operation acting on a region outside the first interface; and
in response to the second operation of dragging the second object into the first interface being detected, the second object is sent to the second terminal.
In these embodiments of the present disclosure, a second object may also be displayed on the display screen of the first terminal. For example, the second object may be a document file on the desktop of the first terminal, or may be a picture file in an image list interface. When the first terminal detects the second operation of dragging the second object into the first interface, the first terminal may send the second object to the second terminal, so that the second terminal can store the second object.
It can be understood that in these embodiments, when the first terminal detects the second operation of dragging the second object outside the first interface into the first interface, the second terminal may send the second object, so that the second object can be saved for use, thereby realizing the function of transmitting files from the first terminal to the second terminal.
In these embodiments of the present disclosure, based on a mutual file transmission function as provided, the intelligence of a screen projection application is further improved, and the use experience is improved.
In some embodiments, the first object may be a file or a program. Operation S13 may include that:
in response to the first operation of opening the first object in the first interface being detected, the first object is opened in the first terminal.
In these embodiments, the first object may be, for example, a word document, a music file or a picture file, or the like, or a music application program in the second terminal. When the first object is a file or a program, the first operation may be an opening operation on the file or the program, namely, the first object can be opened directly in the first terminal.
It is to be noted that in these embodiments of the present disclosure, when the first object is a file and when the first terminal detects an opening operation on the file, the file sent by the second terminal may be received and opened using a tool in the first terminal. For example, the first object may be a word document, and the first terminal may use its own Microsoft office Word tool to open the document. When a corresponding tool is not installed in the first terminal to open the file, the first terminal may automatically download and install the corresponding tool to open the file.
When the first object is a program and when the first terminal detects an opening operation on the program, it can be determined in advance whether the program of the same version as that of the second terminal is installed in the first terminal. When installed, the program installed in the first terminal may be directly opened. For example, the first terminal may be a PC, the second terminal may be a tablet computer, and the program may be a game program. When the program of the same version as that of the second terminal is not installed in the first terminal, the first terminal also can automatically download and install the program and then open the program.
It can be understood that in these embodiments, on one hand, since a user pays more attention to the first terminal when projecting the first interface of the second terminal to the first terminal, there is no need for the user to open a file or a program using the second terminal, thereby providing convenience to the user. On the other hand, since the display screen of the first terminal may be larger than that of the second terminal, the visual experience of the user can be improved. In addition, the hardware processing capacity of the first terminal is better than that of the second terminal. Therefore, the response speed of the first operation can be increased, thereby improving the use experience. Moreover, in these embodiments, when a tool capable of opening a file or a program is not installed in the first terminal, the file or the program may be automatically installed and opened, which has the characteristics of intelligence.
It is to be noted that in these embodiments of the present disclosure, when the first object is opened in the first terminal, the first object may not need to be opened in the second terminal synchronously, thereby saving the power consumption of the second terminal.
In some embodiments, the first object may be a file. The operation of responding to, in response to the first operation on the first object in the first interface being detected, the first operation on the first object in the first terminal may include that:
in response to the first operation of editing the file being detected, the file is opened in the first terminal, and the file is edited; and
the edited file is sent to the second terminal.
In these embodiments, when the first terminal detects the first operation of editing the file, for example, the first terminal detects a modification operation on a word document, or a modification of a Microsoft Office PowerPoint (PPT) file or a modification of a picture file, the first terminal may use a tool to open the file and perform the editing operation. For example, for a picture file, the Photoshop tool may be used to perform the image editing operation. After finishing editing the file, the first terminal may automatically send the edited file to the second terminal.
It can be understood that in these embodiments, the first terminal can not only open the file in the second terminal, but also use its own tools to edit the file, which not only provides convenience to a user, but also enhances the visual experience of the user. The hardware processing capability of the first terminal may be further utilized to increase the response speed of the file editing operation, thereby improving the use experience. In addition, after the first terminal edits the file, there is no need to receive a dragging operation of the user and send the file to the second terminal based on a file dragging operation, but rather the edited file is automatically shared, and the convenience of file return is improved.
In some embodiments, the first object is a link address. Operation S13 may include that:
in response to the first operation acting on the link address in the first interface being detected, the first terminal opens a page connected to the link address according to the link address.
In these embodiments, when the first object is a link address, the link address may be a web address in a WeChat dialog interface, or a web address associated with news title information in a news interface. When the first terminal detects the first operation acting on the link address, such as a click operation, the first terminal may open a page connected to the link address.
It can be understood that in these embodiments, the first terminal is used to open the page connected to the link address, which can not only improve the visual experience of a user, but also further increase the page opening speed, thereby improving the user experience.
In some embodiments, the first object may include an interface added control.
Operation S13 may include that:
in response to the first operation acting on the interface added control being detected, a second interface of the second terminal is projected on the display screen of the first terminal.
In these embodiments, the first interface may further include an interface control.
The interface control may include an interface added control, and may further include an interface close control and the like. The interface control may be hidden from the display screen of the first terminal, and displayed on the display screen based on the user's operation detected by the first terminal. For example, when the first terminal detects a sliding operation of the mouse near a first interface region, the interface control may be displayed. Further, when the first terminal detects the first operation acting on the interface added control, a second interface of the second terminal may be projected on the display screen of the first terminal. The first operation may be, for example, a click operation on the interface added control. It is to be noted that the second interface may also be any interface of the second terminal, for example, a desktop of the second terminal, a Hiboard desktop, or a setting interface.
It can be understood that in these embodiments, when the first terminal detects the first operation acting on the interface added control, a second interface of the second terminal may be projected on the display screen of the first terminal, so that the first terminal may receive multiple shared tasks of the second terminal, which further provides convenience for the first terminal to operate multiple tasks in the second terminal.
In some embodiments, the second interface may include a desktop of the second terminal. The method may further include that:
in response to a third operation of dragging an icon of a target application on the desktop out of the desktop being detected, a third interface of the target application may be projected on the display screen of the first terminal.
In these embodiments, the second interface may be a desktop of the second terminal. When the first terminal detects a third operation of dragging an icon of a target application on the desktop out of the desktop, a third interface of the target application may be projected on the display screen of the first terminal. For example, when the target application is a WeChat application, the third interface may be a chat interface of a WeChat application. For another example, when the target application is a video application, the third interface may be a home page of the video application.
It can be understood that in these embodiments, when the first terminal detects a third operation of dragging an icon of a target application on the desktop to a region outside the desktop, a third interface of the target application may be projected on the display screen of the first terminal. In this way, when the user needs to open a new application during the screen projection process, there is no need to open the target application in the second terminal and then project the interface to the first terminal, but an icon of the target application can be directly dragged in the first terminal. It has the characteristics of intelligence.
It is to be noted that in these embodiments of the present disclosure, when multiple interfaces of the second terminal are displayed on the display screen of the first terminal, operations on any interface may be responded in the first terminal. For example, the display screen of the first terminal may display a picture based on a click operation on a picture in a picture list interface (first interface) of the second terminal, or may display a message received in a WeChat chat interface (third interface) on the display screen of the first terminal.
In some embodiments, the method may further include that:
in response to the first operation of dragging the first object from the first interface to the third interface being detected, a first object copying instruction is sent to the second terminal, the first object copying instruction being configured to instruct the second terminal to copy the first object from the first interface to the third interface; and
in response to a fourth operation of dragging a third object from the third interface to the first interface being detected, a third object copying instruction is sent to the second terminal, the third object copying instruction being configured to instruct the second terminal to copy the third object from the third interface to the first interface.
In these embodiments, different interfaces may interact based on an interaction operation detected by the first terminal. When the first terminal detects the first operation of dragging a first object from the first interface to the third interface, a first object copying instruction may be sent to the second terminal, so that the second terminal may copy the first object from the first interface to the third interface according to the first object copying instruction. When the first terminal detects the fourth operation of dragging a third object from the third interface to the first interface, a third object copying instruction may be sent to the second terminal, so that the second terminal may copy the third object from the third interface to the first interface according to the third object copying instruction.
It can be understood that in these embodiments, the first terminal may control the information interaction between different interfaces, so that the screen projection application of the first terminal is more intelligent, a user does not need to operate on the second terminal when there is an additional information copying need while paying more attention to the first terminal.
In some embodiments, the first interface may include a message prompt interface, and the interface added control may include a message display control.
The operation of projecting, in response to the first operation acting on the interface added control being detected, a second interface of the second terminal on the display screen of the first terminal may include that:
in response to the first operation acting on the message display control in the message prompt interface being detected, a message display interface of the second terminal is projected on the display screen of the first terminal.
In these embodiments, the first interface projected on the first terminal may be a message prompt interface of the second terminal, and there may be a message display control on the message prompt interface. When the first terminal detects the first operation acting on the message display control, for example, a click operation on the message display control detected by the first terminal, the message display interface of the second terminal may be projected on the display screen of the first terminal.
It can be understood that in these embodiments, the first terminal may also project a message prompt interface when the second terminal receives the message. Based on the operation in the first terminal, a user may project the message display interface of the second terminal on the first terminal. There is no need for the user to operate on the second terminal when the second terminal receives a message while paying more attention to the first terminal, which improves the user experience.
In S21, a first interface is projected to a display screen of a first terminal.
In S22, a first operation detected by the first terminal on a first object in the first interface is responded.
In these embodiments of the present disclosure, the second terminal may be a smart phone or other smart devices with a display screen, such as a smart speaker.
As described in the first terminal section, the second terminal may be connected to the first terminal in various ways. Moreover, after the first connection, the second terminal and the first terminal may also be automatically connected based on user account information to improve the user experience.
Based on the connection established with the first terminal, the second terminal may project the first interface to the first terminal based on operation S21. The first interface may be a desktop, a setting interface, or an application interface of an application presently being displayed, which is not limited in these embodiments of the present disclosure.
Based on the projected first interface, the second terminal may respond to the first operation on the first object in the first interface detected by the first terminal in operation S22.
It can be understood that in these embodiments, the second terminal can not only actively share its own first interface, but also respond to the first operation detected by the first terminal on the first object in the first interface. Through cooperation between the second terminal and the first terminal, the multi-screen interaction is more interactive.
In some embodiments, the operation to which a first operation detected by the first terminal for a first object in the first interface is responded may include that:
in response to the first operation being detected by the first terminal to drag the first object in the first interface out of the first interface, the first object is sent to the first terminal.
In these embodiments of the present disclosure, when the first operation is dragging the first object in the first interface out of the first interface, the second terminal may send the first object to the first terminal, so that the first terminal can store the first object locally.
It can be understood that in these embodiments, the first object may be sent to the first terminal based on the first operation of the second terminal responding to the drag, and the function of transmitting files from the second terminal to the first terminal is realized.
In some embodiments, the method may further include that:
a second object sent by the first terminal is received, the second object being sent after the first terminal detects a second operation of dragging a second object outside the first interface into the first interface; and
the second object is saved.
In these embodiments of the present disclosure, the second object may also be displayed on the display screen of the first terminal. For example, the second object may be a document file on the desktop of the first terminal, or may be a picture file in an image list interface. When the first terminal detects that the second object is dragged into the first interface, the first terminal may send the second object to the second terminal, and the second terminal may store the second object based on the received second object.
It can be understood that in these embodiments, the second terminal can not only send out an object, but also receive the second object from the first terminal, thereby realizing the function of receiving a file by the second terminal.
In some embodiments, the first object may be a file. Operation S22 may include that:
an edited file sent by the first terminal is received, the file being a file stored in the second terminal and opened in the first terminal; and
the edited file is saved.
In these embodiments, the first terminal may use a tool in the first terminal to open the file and perform the editing operation. After finishing editing the file, the first terminal may automatically send the edited file to the second terminal. The file may come from the second terminal, for example, a picture file projected by the second terminal on the picture list interface of the first terminal.
It can be understood that in these embodiments, after the first terminal edits the file from the second terminal, the second terminal may receive and save the edited file sent by the first terminal, the file editing operation becomes more convenient due to good hardware processing capability of the first terminal. Based on the automatic transmission of the first terminal, the convenience of file return is improved.
In some embodiments, the first object may be an interface added control. The operation to which a first operation detected by the first terminal for a first object in the first interface is responded may include that:
in response to the first operation being detected by the first terminal to act on the interface added control, a second interface is projected to the display screen of the first terminal.
In these embodiments, the first interface may further include an interface control.
The interface control may include an interface added control, and may further include an interface close control and the like. The interface control may be hidden from the display screen of the first terminal, and displayed on the display screen based on the user's operation detected by the first terminal. For example, when the first terminal detects a sliding operation of a mouse near a first interface region, the interface control may be displayed. Further, when the first operation is a first operation detected by the first terminal and acting on the interface added control, the second terminal may project a second interface to the display screen of the first terminal. It is to be noted that the second interface may also be any interface of the second terminal, for example, a desktop of the second terminal, a Hiboard desktop, or a setting interface.
It can be understood that in these embodiments, when the first operation is the first operation detected by the first terminal and acting on the interface added control, the second terminal may continuously project the second interface, so that the first terminal may receive multiple shared tasks from the second terminal, which further provides convenience for the first terminal to operate multiple tasks in the second terminal.
In some embodiments, the second interface may include a desktop of the second terminal. The method may further include that:
in response to the first operation being a third operation detected by the first terminal for dragging an icon of a target application on the desktop out of the desktop, a third interface of the target application is projected to the display screen of the first terminal.
In these embodiments, the second interface may be a desktop of the second terminal. When the first operation is a third operation detected by the first terminal for dragging an icon of a target application on the desktop to a region outside the desktop, the second terminal may project a third interface of the target application on the display screen of the first terminal. For example, when the target application is a WeChat application, the third interface may be a chat interface of a WeChat application. For another example, when the target application is a video application, the third interface may be a home page of the video application.
It can be understood that in these embodiments, when a user needs to open a new application during a screen projection process, there is no need to open a target application in the second terminal and then project the interface to the first terminal, but the second terminal may open an application in the first terminal according to an icon dragging operation detected by the first terminal. It has the characteristics of intelligence.
In some embodiments, the method may further include that:
a first object copying instruction or a third object copying instruction is received;
the first object copying instruction may be sent after the first terminal detects the first operation of dragging a first object from the first interface to the third interface, and the third object copying instruction may be sent after the first terminal detects a fourth operation of dragging a third object from the third interface to the first interface;
the first object in the first interface is copied to the third interface according to the first object copying instruction; or,
the third object in the third interface is copied to the first interface according to the third object copying instruction.
In these embodiments, different interfaces may interact based on an interaction operation detected by the first terminal. When the first terminal detects the first operation of dragging the first object from the first interface to the third interface, the second terminal may receive a first object copying instruction from the first terminal, and copy the first object from the first interface to the third interface according to the first object copying instruction. Similarly, the second terminal may also copy the third object from the third interface to the first interface according to a received third object copying instruction.
It can be understood that in these embodiments, the second terminal may control the information interaction between different interfaces according to the copying instruction of the first terminal, so that the screen projection application of the first terminal is more intelligent, a user does not need to operate on the second terminal when there is an information copying requirement while paying more attention to the first terminal.
In some embodiments, the first interface may include a message prompt interface, and the interface added control may include a message display control.
The operation of projecting, in response to the first operation being detected by the first terminal to act on the interface added control, a second interface to the display screen of the first terminal may include that:
in response to the first operation being detected by the first terminal to act on the interface display control in the message prompt interface, a message display interface is projected to the display screen of the first terminal.
In these embodiments, the first interface projected on the first terminal may be a message prompt interface of the second terminal, and there may be a message display control on the message prompt interface. When the first operation is a first operation detected by the first terminal and acting on the message display control, the second terminal may project a message display interface to the display screen of the first terminal.
It can be understood that in these embodiments, it is not necessary for a user who is paying more attention to the first terminal to operate on the second terminal when the second terminal receives a message on the premise. The second terminal can directly project the message display interface to the display screen of the first terminal in response to the operation of the first terminal, which improves the user experience.
In some embodiments, the screen projection method applied to a second terminal may further include that:
a screen projection control interface is displayed;
a fifth operation acting on the screen projection control interface is detected; and
in response to the fifth operation on a fourth object in the screen projection control interface being detected, the fifth operation is responded.
In these embodiments, after the second terminal may establish a connection with the first terminal, a screen projection control interface may be displayed on the display screen of the first terminal. The screen projection control interface may include multiple fourth objects, for example, multiple controls, which may enable a user to implement different functions based on the fifth operation on different controls.
It can be understood that in these embodiments, when the second terminal performs a screen projection application, a screen projection control interface may be displayed on the display screen of the second terminal, and user operations on a fourth object on the screen projection control interface may be received, so as to meet the control requirements of customers on the screen projection application. For example, targeted control operations may be performed to respond to different application requirements, so that the user experience can be improved. In addition, the first terminal may only display the screen projection control interface during the screen projection process. For example, when the first object is opened in the first terminal, a file or an application program may be opened, the first object may not need to be opened in the second terminal synchronously, thereby saving the power consumption of the second terminal.
In some embodiments, the fourth object may include a silence setting control.
The operation of responding to the fifth operation when the fifth operation on a fourth object in the screen projection control interface is detected may include that:
in response to the fifth operation on the silence setting control being detected, the second terminal is set as a silent mode.
In these embodiments, the fourth object may be a silence setting control on the screen projection control interface. As shown in
As mentioned above, a message prompt interface may be displayed in the first terminal, and a message display interface may also be opened based on the first operation of the user. It can be understood that in these embodiments, when the second terminal receives the fifth operation of a user on the silence setting control, the second terminal may be set as the silent mode, so that the user can concentrate on the first terminal, and when there is, for example, a notification message, the notification message may be viewed directly on the first terminal, which provides convenience to the user.
In S31, the second terminal projects a first interface on a display screen of the first terminal.
In S32, the first terminal detects a first operation acting on the first interface.
In S33, when the first terminal detects the first operation on a first object in the first interface, the first operation on the first object is responded in the first terminal.
In S34, the second terminal responds to the first operation detected by the first terminal on a first object in the first interface.
It can be understood that in these embodiments of the present disclosure, a first terminal can receive the sharing of a second terminal, and the second terminal can be controlled directly by an operation detected by the first terminal on a first interface displayed by the first terminal. An interactive user operation between the first terminal and the second terminal is simplified, and it is favorable for selecting the first terminal and/or the second terminal which are/is more suitable for a present application scenario based on an operation input by a user to perform corresponding operations, thereby upgrading the user experience and making multi-screen interaction more intelligent.

While this specification contains many specific implementation details, these should not be construed as limitations on the scope of any claims, but rather as descriptions of features specific to particular implementations. Certain features that are described in this specification in the context of separate implementations can also be implemented in combination in a single implementation. Conversely, various features that are described in the context of a single implementation can also be implemented in multiple implementations separately or in any suitable subcombination.
Moreover, although features can be described above as acting in certain combinations and even initially claimed as such, one or more features from a claimed combination can in some cases be excised from the combination, and the claimed combination can be directed to a subcombination or variation of a subcombination.
Similarly, while operations are depicted in the drawings in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results. In certain circumstances, multitasking and parallel processing can be advantageous. Moreover, the separation of various system components in the implementations described above should not be understood as requiring such separation in all implementations, and it should be understood that the described program components and systems can generally be integrated together in a single software product or packaged into multiple software products.
As such, particular implementations of the subject matter have been described. Other implementations are within the scope of the following claims. In some cases, the actions recited in the claims can be performed in a different order and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results.

It should be understood that “a plurality” or “multiple” as referred to herein means two or more. “And/or,” describing the association relationship of the associated objects, indicates that there may be three relationships, for example, A and/or B may indicate that there are three cases where A exists separately, A and B exist at the same time, and B exists separately. The character “/” generally indicates that the contextual objects are in an “or” relationship.
In the present disclosure, it is to be understood that the terms “lower,” “upper,” “under” or “beneath” or “underneath,” “above,” “front,” “back,” “left,” “right,” “top,” “bottom,” “inner,” “outer,” “horizontal,” “vertical,” and other orientation or positional relationships are based on example orientations illustrated in the drawings, and are merely for the convenience of the description of some embodiments, rather than indicating or implying the device or component being constructed and operated in a particular orientation. Therefore, these terms are not to be construed as limiting the scope of the present disclosure.
Moreover, the terms “first” and “second” are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated.
