Detailed descriptions will be made below respectively.

First Embodiment

In the embodiment, descriptions are made from the point of a sending terminal. A method for interaction between terminals includes that: a keyboard operation message is received; indication information of a corresponding operated key is acquired according to the keyboard operation message; key meaning information corresponding to the indication information is acquired according to a preset keyboard escape table; the indication information and the corresponding key meaning information are displayed in a shared screen; and contents displayed in the shared screen are sent to a target terminal when a sharing request of the target terminal is received.

Referring to FIG. 1, FIG. 1 is a flowchart of a method for interaction between terminals according to a first embodiment of the invention. The method includes the following steps.

Step 101: a keyboard operation message is received.

It may be understood that the keyboard operation message may be triggered to be sent by clicking a key of a keyboard by a user; and before the keyboard operation message is received, it is required to perform presetting operation to enable a terminal to obtain the keyboard operation message at any time.

For example: a global keyboard hook is registered, that is, a keyboard hook is registered, which refers to intercepting and processing a keyboard message in advance by using an Application Programming Interface (API). The global hook is one of system hooks, and when some specified messages are processed by any application program in a system, the hook is called.

Step 102: indication information of a corresponding operated key is acquired according to the keyboard operation message.

That is, the terminal acquires indication information of a corresponding operated key according to the keyboard operation message, wherein the indication information is mainly configured to indicate information about a key currently operated by the user. For example, when the user presses key “F3”, the indication information indicates “F3”, and for another example, when the user simultaneously presses keys “Ctrl” and “N”, the indication information indicates “Ctrl+N”.

Furthermore, after “the keyboard operation message is received” and before “the indication information of the corresponding operated key is acquired according to the keyboard operation message”, the method may further include that:

(1) a window of a currently obtained window focus is determined; and

(2) a terminal application which processes the keyboard operation message is determined according to the window of the currently obtained window focus.

It may be understood that a window is a message receiving entity in a Windows system, and windows may send the keyboard operation message to the window of the currently obtained window focus. Each execution thread may only can configure or acquire a focus of a window created by the current thread, so that mutual influence of application programs may be prevented; and a response delay of a certain application program may not make another application program pause its response to an operation of the user.

For example, when the terminal determines the window of the currently obtained window focus and determines that terminal application “PhotoShop” processes the keyboard operation message according to the window of the currently obtained window focus, the terminal acquires the indication information of the corresponding operated key according to the keyboard operation message on the basis of “PhotoShop”.

Step 103: key meaning information corresponding to the indication information is acquired according to a preset keyboard escape table.

In the above, the keyboard escape table is preset, and it mainly records a corresponding relationship between operated key information and key meaning information; and it may be understood that keyboard escape tables are correspondingly set for each of different terminal applications.

For example, before “the keyboard meaning information corresponding to the indication information is acquired according to the preset keyboard escape table”, the corresponding preset keyboard escape table may also be acquired according to the determined terminal application, and then, the key meaning information corresponding to the indication information is acquired on the basis of the terminal application and the corresponding keyboard escape table.

Step 104: the indication information and the corresponding key meaning information are displayed in a shared screen.

Step 105: contents displayed in the shared screen are sent to a target terminal when a sharing request of the target terminal is received.

In the above, Step 104 and Step 105 may specifically be implemented as follows.

It may be understood that the shared screen is a terminal screen of a sender, and after the indication information and the corresponding key meaning information are acquired, the indication information and the corresponding key meaning information may be displayed in a preset area of the shared screen together, wherein the preset area may be an area on a left lower part or right lower part of the terminal screen of the sender, or may be displayed in a floating window form, or in a semitransparent control form or the like without influence on the query about other contents displayed on the terminal screen.

Furthermore, the contents displayed in the shared screen are sent to the target terminal when the sharing request of the target terminal is received, and are displayed in a terminal screen of the target terminal, wherein a connection may be pre-established between the sender and a receiver (i.e. the target terminal) to enable a user of the receiver to clearly know a practical operation of the user of the sender according to the indication information and the corresponding key meaning information.

From the above, it can be seen that: according to the method for interaction between the terminals provided by the embodiment, indication information of a corresponding operated key is acquired according to a keyboard operation message input by the user, the corresponding key meaning information is acquired according to the preset keyboard escape table, the indication information and the corresponding key meaning information are displayed together, and contents displayed in the shared screen are sent to the target terminal when the sharing request of a receiver (i.e. the target terminal) is received; and in the embodiment of the invention, the sender sends both the information of indicating the operated key and the corresponding key meaning information to the receiver, and compared with an existing manner of only providing limited one-way propagation, such a manner has the advantages that the receiver may clearly and directly know the practical operation of the sender, and propagation effects between the terminals may be improved.

Second Embodiment

According to the method described in the first embodiment, detailed descriptions will be further made with an example.

At first, a sending terminal (such as terminal A) and receiving terminals (such as terminal B1, terminal B2, . . . terminal BN, wherein N represents the number of the receiving terminals) establish network connections (such as remote-education-based network connections), so that the sending terminal may send contents in a shared screen to the receiving terminals, the shared contents including image contents required to be displayed and further including indication information about a key operated by a user of the sending terminal and corresponding key meaning information.

Referring to FIG. 2a, FIG. 2a is a flowchart of a method for interaction between terminals according to a second embodiment of the invention. It may be understood that user A is an operating user of terminal A as shown in FIG. 2a, which is disclosed not as a part of a system where the interaction method is executed but only for facilitating understanding, and the method includes the following steps.

Step 201: terminal A registers a global keyboard hook.

Terminal A pre-registers a keyboard hook, and the keyboard hook refers to intercepting and processing a keyboard message in advantage by using an API. The global keyboard key is one of systems hooks, and when some specified messages are processed by any application program in a system, the hook is called.

It may be understood that a hook is a very important system interface in a Windows system, and it may be adopted to intercept and process a message sent to another application program to realize a function which is difficult to be realized by an ordinary application program. There are many types of hooks, each type of the hooks may intercept and process a corresponding message, and for example, the keyboard hook in the embodiment may intercept a keyboard message.

Step 202: user A triggers to send a keyboard operation message by clicking a key of a keyboard of terminal A.

Step 203: terminal A receives the keyboard operation message sent by user A through the global keyboard hook.

In the above, Step 202 and Step 203 may specifically be implemented as follows.

For example, user A simultaneously presses keys “Ctrl” and “N” through the keyboard to send the keyboard operation message to terminal A, and terminal A may acquire the keyboard operation message by using the global keyboard hook.

Step 204: terminal A determines a window of a currently obtained window focus.

Step 205: terminal A determines a terminal application which processes the keyboard operation message according to the window of the currently obtained window focus.

Step 206: terminal A acquires indication information of the corresponding operated key according to the keyboard operation message on the basis of the terminal application.

In the above, Step 204 and Step 206 may specifically be implemented as follows.

A window is a message receiving entity in a Windows system, and windows may send the keyboard operation message to the window of the currently obtained window focus. Each execution thread may only configure or acquire a focus of a window created by the current thread, so that mutual influence of application programs may be prevented; and a response delay of a certain application program may not make another application program pause its response to an operation of the user.

For example, when the terminal A determines the window of the currently obtained window focus and determines that terminal application “PhotoShop” processes the keyboard operation message according to the window of the currently obtained window focus, the terminal A acquires the indication information of the corresponding operated key according to the keyboard operation message on the basis of “PhotoShop”.

In the above, the indication information is mainly configured to indicate information about the key currently operated by the user. For example, when the user presses key “F3”, the indication information indicates “F3”, and for another example, when the user simultaneously presses keys “Ctrl” and “N”, the indication information indicates “Ctrl+N”.

Step 207: terminal A acquires a preset corresponding keyboard escape table according to the terminal application.

Step 208: terminal A acquires key meaning information corresponding to the indication information according to the preset keyboard escape table.

In the above, Step 207 to Step 208 may specifically be implemented as follows.

The keyboard escape table is preset, and it mainly records a corresponding relationship between operated key information and key meaning information; and it may be understood that keyboard escape tables are correspondingly set for each of different terminal applications.

For example, a preset corresponding keyboard escape table is acquired according to the determined terminal application “PhotoShop”, as shown in Table 1, and then, the key meaning information corresponding to the indication information is acquired on the basis of the terminal application and the corresponding keyboard escape table.

TABLE 1
Key meaning information    Indication information of operated key
Create                     Ctrl + N
Open                       Ctrl + O
Open as                    Alt + Shift + Ctrl + O
Save                       Ctrl + S
Save as                    Shift + Ctrl + S or Alt + Ctrl + S
Print                      Ctrl + P
Exit                       Ctrl + Q
Revoke (or called as Undo) Ctrl + Z
Step forward               Shift + Ctrl + Z
Step backward              Alt + Ctrl + Z
Copy                       Ctrl + C or F3
Paste                      Ctrl + V F4
Free transform             Ctrl + T
Transform again            Shift + Ctrl + T
Color setting              Shift + Ctrl + K

It may be understood that the keyboard escape tables are correspondingly set for each terminal application, which is pre-configured by a developer, and Table 1 is only an example for description and not intended to limit the corresponding relationship between the key meaning information and the indication information of the operated key.

Step 209: terminal A displays the indication information and the corresponding key meaning information in a preset area of the shared screen.

Step 210: terminal A sends contents displayed in the shared screen to a receiving terminal.

In the above, Step 209 and Step 210 may specifically be implemented as follows.

After the indication information and the corresponding key meaning information are acquired, the indication information and the corresponding key meaning information may be displayed in the preset area of the shared screen of terminal A together, wherein the preset area may be an area on a left lower part or right lower part of the terminal screen of the terminal A, or may be displayed in a floating window form, a semitransparent control form or the like without influence on query about other contents displayed on the terminal screen. FIG. 2b is a display diagram of the shared screen.

For example, terminal A displays a curriculum operated by PhotoShop to the receiving terminals (terminal B1, terminal B2, . . . terminal BN) in a remote education manner. Key operation information of terminal A is displayed on the screen by using an existing video function of the shared screen of terminal A (such as a computer of a teacher) at first, and then is sent to a receiving terminal (such as a computer of a student) by using a screen sharing function, so that the student may see a keyboard operation of the teacher. In addition, when the keyboard operation of the teacher is displayed, a shortcut key meaning of the keyboard operation is also displayed. Herein, a key on which the keyboard operation is executed and the meaning are mapped into a “keyboard escape table”.

For another example, during specific implementation, terminal A determines a program (for example, PhotoShop is determined) which processes the keyboard message through the window of the currently obtained window focus, after terminal A acquires the keyboard operation of the teacher. Then, the “keyboard escape table” is queried to obtain its Chinese meaning in combination with the corresponding key, and the Chinese meaning and the key are both displayed in a screen area shared by the teacher.

At this moment, the keyboard shortcut key operation of the teacher is displayed to the student, and as shown in FIG. 2b, the student watches a screenshot demonstrated by the teacher. In a conventional online class, only a change on the screen of the teacher may be seen, but the student is not sure about an operation, which causes the change, of the teacher (such as pressing a key on the keyboard). In such a display method, the operation which is executed by the teacher may be displayed on a left side of a shared interface in real time. For example, referring to Table 1, if the teacher simultaneously presses keys “Ctrl” and “Z” in “PhotoShop”, the student may synchronously see “Ctrl+Z” on the left side of the screen and also see its Chinese meaning “Revoke”.

From the above, according to the method for interaction between terminals provided by the embodiment, indication information of a corresponding operated key is acquired according to a keyboard operation message input by the user, the corresponding key meaning information is acquired according to the preset keyboard escape table, the indication information and the corresponding key meaning information are displayed together, and contents displayed in the shared screen are sent to a target terminal when the sharing request of a receiver (i.e. the target terminal) is received; and in the embodiment of the invention, the sender sends both the information of indicating the operated key and the corresponding key meaning information to the receiver, and compared with an existing manner of only providing limited one-way propagation, such a manner has the advantages that the receiver may clearly and directly know the practical operation of the sender, and propagation effects between the terminals may be improved. For example, during remote network-based education, a receiver may clearly know a practical operation of a sender according to the information of indicating the operated key and the corresponding key meaning information, which are sent by a sender, so that accuracy of a directional teaching operation and teaching real-time performance are improved, and understanding of the user of the receiver is facilitated.

Third Embodiment

It may be understood that the keyboard operation message may be triggered to be sent by clicking a key of a keyboard by a user; and before the keyboard operation message is received, it is required to perform a presetting operation to enable a terminal to obtain the keyboard operation message at any time.

For example: a global keyboard hook is registered, that is, a keyboard hook is registered, which refers to intercepting and processing a keyboard message in advance by using an Application Programming Interface (API). The global keyboard hook is one of system hooks, and when some specified messages are processed by any application program in a system, the hook is called.

The first acquiring module 302 acquires indication information of a corresponding operated key according to the keyboard operation message, wherein the indication information is mainly configured to indicate information about a key currently operated by a user. For example, when the user presses key “F3”, the indication information indicates “F3”, and for another example, when the user simultaneously presses keys “Ctrl” and “N”, the indication information indicates “Ctrl+N”.

The second acquiring module 303 is configured to acquire key meaning information corresponding to the indication information according to a preset keyboard escape table.

In the above, the keyboard escape table is preset, and it mainly records a corresponding relationship between operated key information and key meaning information; and it may be understood that keyboard escape tables are correspondingly set for each of different terminal applications.

For example, before “the keyboard meaning information corresponding to the indication information is acquired according to the preset keyboard escape table”, the corresponding preset keyboard escape table may also be acquired according to the determined terminal application, and then, the key meaning information corresponding to the indication information is acquired on the basis of the terminal application and the corresponding keyboard escape table.

The displaying module 304 is configured to display the indication information and the corresponding key meaning information in a shared screen; and the sharing and sending module 305 is configured to send the contents displayed in the shared screen to a target terminal when a sharing request of the target terminal is received.

It may be understood that the shared screen is a terminal screen of a sender, and after the indication information and the corresponding key meaning information are acquired, the indication information and the corresponding key meaning information may be displayed in a preset area of the shared screen together, wherein the preset area may be an area on a left lower part or right lower part of the terminal screen of the sender, or may be display in a floating window form, a semitransparent control form or the like without influence on query about other contents displayed on the terminal screen.

Furthermore, the contents displayed in the shared screen are sent to the target terminal when the sharing request of the target terminal is received, and are displayed in a terminal screen of the target terminal, wherein a connection may be pre-established between the sender and a receiver (i.e. the target terminal) to enable a user of the receiver to clearly know a practical operation of the user of the sender according to the indication information and the corresponding key meaning information.

From the above, it can be seen that: according to the device for interaction between the terminals provided by the embodiment, the device is integrated in a sending terminal, acquires indication information of a corresponding operated key according to a keyboard operation message input by the user, acquires corresponding key meaning information according to a preset keyboard escape table, displays the indication information and the corresponding key meaning information together, and sends contents displayed in the shared screen to the target terminal when the sharing request of a receiver (i.e. the target terminal) is received; and in the embodiment of the invention, the sender sends both the information of indicating the operated key and the corresponding key meaning information to the receiver, and compared with an existing manner of only providing limited one-way propagation, such a manner has the advantages that the receiver may clearly and directly know the practical operation of the sender, and propagation effects between the terminals may be improved.

Fourth Embodiment

Referring to FIG. 4, FIG. 4 is a structure diagram of a device for interaction between terminals according to an embodiment of the invention, wherein the device for interaction between the terminals includes: a receiving module 401, a first acquiring module 402, a second acquiring module 403, a displaying module 404 and a sharing and sending module 405, wherein functions of each function module in the embodiment may sequentially and correspondingly refer to related descriptions about the receiving module 301, first acquiring module 302, second acquiring module 303, displaying module 304 and sharing and sending module 305 in the third embodiment, and will not be elaborated herein.

It may be understood that a window is a message receiving entity in a Windows system, and windows may send the keyboard operation message to the window of the currently obtained window focus. Each execution thread may only configure or acquire a focus of a window created by the current thread, so that mutual influence of application programs may be prevented; and a response delay of a certain application program may not make another application program pause its response to an operation of the user.

For example, when the determining module 406 determines the window of the currently obtained window focus and determines that terminal application “PhotoShop” processes the keyboard operation message according to the window of the currently obtained window focus, the first acquiring module 402 acquires the indication information of the corresponding operated key according to the keyboard operation message on the basis of “PhotoShop”.

The keyboard escape table is preset, and it mainly records a corresponding relationship between operated key information and key meaning information; and it may be understood that keyboard escape tables are correspondingly set for each of different terminal applications.

For example, the corresponding preset keyboard escape table is acquired according to the determined terminal application “PhotoShop”, and then, the key meaning information corresponding to the indication information is acquired on the basis of the terminal application and the corresponding keyboard escape table.

Alternatively, the device may further include: a registering module 407, configured to register a global keyboard hook; and then the receiving module 401 is configured to receive the keyboard operation message through the global keyboard hook.

That is, the registering module 407 pre-registers the keyboard hook, and the keyboard hook refers to intercepting and processing a keyboard message in advance by using an API. The global keyboard key is one of systems hooks, and when some specified messages are processed by any application program in a system, the hook is called. For example, the keyboard hook in the embodiment may intercept the keyboard message.

The receiving module 401 may further be configured to receive the keyboard operation message triggered to be sent by clicking a key of a keyboard by a user. For example, when user A simultaneously presses keys “Ctrl” and “N” through the keyboard to send the keyboard operation message to terminal A, and terminal A acquires the keyboard operation message by virtue of the global keyboard hook.

After the indication information and the corresponding key meaning information are acquired, the displaying module 404 may further be configured to display the indication information and the corresponding key meaning information in a preset area of the shared screen.

That is, the indication information and the corresponding key meaning information may be displayed in the preset area of the shared screen of terminal A together, wherein the preset area may be an area on a left lower part or right lower part of the terminal screen of the sender, or may be displayed in a floating window form, or a semitransparent control form or the like without influence on query about other contents displayed on the terminal screen.

During specific implementation, each of the abovementioned modules may be implemented as independent entities, and may also be freely combined for implementation as the same entity or a plurality of entities, and specific implementation of each of the abovementioned modules may refer to the abovementioned second method embodiment, and will not be elaborated herein.
