A screen sharing apparatus according to an embodiment of the present invention will be described below with reference to the drawings.
A screen sharing device 10 according to the present embodiment shown in FIG. 1 is a device that enables screen sharing in online communication between a plurality of terminals, and constitutes part of the functions of the online communication system 1 .
Online communication here means video on networks represented by systems such as Zoom (registered trademark), teams (registered trademark), skype (registered trademark), WebEx (registered trademark), bellFace (registered trademark), etc. Calls are also called video chats, video conferences, and the like.

In the following description, it is assumed that the online communication system 1 equipped with the screen sharing device 10 according to the present embodiment is used in a business meeting between an operator and a customer. Here, an operator and a customer use an operator terminal 2 and a customer terminal 3, respectively, and the operator terminal 2 serves as a host for online communication with the customer terminal 3. FIG.

In addition, regarding screen sharing in online communication, a screen on a predetermined terminal that is designated as an object to be shared between terminals may be referred to as a screen to be shared. Also, a screen displayed on a terminal other than the predetermined terminal, which is generated based on the shared screen and displays the same content as the shared screen, may be referred to as a shared screen.

●Functional Configuration The online communication system 1 is configured to be able to communicate with the operator terminal 2 and the customer terminal 3 via a network NW such as the Internet.

The online communication system 1 includes an arithmetic unit such as a CPU (Central Processing Unit), a computer program executed by the CPU, internal memories such as RAM (Random Access Memory) and ROM (Read Only Memory), and the like. The screen sharing device 10 implemented in the online communication system 1 and realizing one function thereof includes a terminal information acquisition unit 11, a synchronization processing unit 12, a display control unit 13, an authority setting unit 14, a detection processing unit 15, a reflection A functional block composed of a processing unit 16 and a dialog generation unit 17 is configured.
The online communication system 1 also includes a communication processing unit 18, and the screen sharing device 10 requires the communication processing unit 18 to execute the functions in order to realize the functions.

Online communication by the online communication system 1 is realized, for example, through a session conforming to the WebSocket standard, but this does not deny the use of communication standards other than WebSocket, such as HTTP and WebRTC. Instead, it is possible to establish a session between the operator terminal 2 and the customer terminal 3 that conforms to these standards. The online communication system 1 also appropriately includes a STUN server, a TURN server, a signaling server, and the like as resources for realizing online communication.

The terminal information acquisition unit 11 acquires terminal information from the operator terminal 2 and the customer terminal 3 .
In the terminal information, at least, as information related to the screen configuration necessary for controlling the display control unit described later, information related to the aspect ratio of the display provided in each terminal, browser program version information and rendering mode information of each terminal etc. are included. However, in addition to this, terminal information includes devices such as webcams and microphones that each terminal has, drivers that control these devices and the OS, information related to application programs, etc., which are required by the terminal for online communication and screen sharing. where appropriate.

Upon receiving a screen sharing instruction from the operator terminal 2, the synchronization processing unit 12 synchronously displays the shared screen displayed on the operator terminal 2 on the customer terminal 3 as a shared screen.
In screen sharing, the operator can designate a screen to be shared in units of application programs, displays, and windows on the operator terminal 2 and allow the customer terminal 3 to share the screen.
In response to this, the synchronization processing unit 12 generates a display area for displaying the shared screen displayed on the operator terminal 2 within the screen of the customer terminal 3 . Then, data obtained by streaming the shared screen displayed on the operator terminal 2 is displayed in the display area.

The display control unit 13 displays the screen to be shared on the screen of the operator terminal 2 according to the screen configuration of the customer terminal 3 .
The display control unit 13 displays the screen to be shared on the screen of the operator terminal 2 at a ratio corresponding to the aspect ratio of the customer terminal 3, for example. That is, by referring to the aspect ratios of the screens of the operator terminal 2 and the customer terminal 3 acquired by the terminal information acquisition unit 11, the screen to be shared is converted into the aspect ratio of the screen of the customer terminal 3 and displayed on the operator terminal 2. display. As a result, when the operation authority is transferred to the customer terminal 3, the operation performed by the customer while viewing the shared screen is accurately reflected on the shared screen. In addition, since the operator can view the shared screen in the same way as the shared screen viewed by the customer, the operator can communicate while being aware of how the customer views the shared screen.
Further, when the display control unit 13 displays the screen to be shared on the screen of the operator terminal 2, the browser type of the customer terminal 3, the switching of the rendering mode of the operator terminal 1, and the like may be taken into account. As a result, regardless of differences in the browsers installed in the operator terminal 2 and the customer terminal 3, or the devices (smartphones, so-called personal computers, etc.) that constitute the operator terminal 2 and the customer terminal 3, the other side of the operator terminal 2 can accurately display the screen to be shared.

The authority setting unit 14 transfers the operation authority of the shared screen on the operator terminal 2 to the customer terminal 3 .
Here, after screen sharing is started in response to a request from the operator terminal 2, the operation authority remains with the operator terminal 2 until the operation authority is transferred. On the other hand, the operator can use the operator terminal 2 to transmit to the screen sharing apparatus 10 a command to transfer the operation authority of the screen to be shared from the operator terminal 2 to the customer terminal 3 . In response to this, the screen sharing device 10 transfers the operation authority of the shared screen on the operator terminal 2 to the customer terminal 3 . As a result, the function of the reflection processing unit 16 is activated, and the customer's operation performed while viewing the shared screen on the customer terminal 3 is reflected on the shared screen.
In this embodiment, when the operation authority is transferred from the operator terminal 2 to the customer terminal 3 side, the operator's operation on the shared screen is invalidated. Operator actions may be treated as valid as long as they do not conflict.

The detection processing unit 15 detects the customer's operation performed on the customer terminal 3 in a state where the operation authority for the shared screen is transferred to the customer terminal 3, and acquires operation information related to the detected operation.

The customer's operation here is, for example, an operation of a pointing device such as a mouse, and includes movement of a pointing position indicated by a cursor, scrolling of a page, and pressing down by a click operation at a predetermined position. The operation information related to these operations is composed of coordinate information before and after movement of the designated position in the coordinate system set on the customer terminal 3, scroll amount, commands according to pressing, and the like.
The result of the operation is embodied on the shared screen by the reflection processing unit 16, which will be described later.

The detection processing unit 15 also detects a state of waiting for input of text in the text input field in the shared screen in a state where the operation authority of the shared screen has been transferred to the customer terminal 3 . That is, when a text input field is provided in the screen to be shared, and as a result of the customer specifying the text input field, the detection processing unit 15 waits for text input. Detect as a state.

The reflection processing unit 16 reflects the operation executed on the customer terminal 3 to which the operation authority has been transferred on the shared screen of the operator terminal 2 . That is, based on the operation information detected and acquired by the detection processing unit 15, the reflection processing unit 16 reproduces the operation corresponding to the operation information on the shared screen.

The reflection processing unit 16 also receives text input by the customer from a text input dialog (to be described later) when the operation authority is delegated to the customer terminal 3, and inputs the text in the text input field in the shared screen. Let

When the detection processing unit 15 detects that the text entry standby state in the text entry field in the shared screen is detected, the dialog generation part 17 generates an input dialog for entering text in the text entry field in the shared screen. A dialog is generated on the customer terminal 3.
The input dialog includes, for example, a text acceptance field for accepting text input, and a confirm button for confirming the content of the text received from the text acceptance field.
Until the confirmation button is pressed, the customer can edit or convert the text entered in the text reception field as appropriate, and the customer enters the text after editing or conversion in the text reception field into the text input field. It can be the content to be done.
In addition, if text has already been entered in the text input field in the shared screen, when creating the input dialog, it is possible to insert the text that has already been entered in the text input field for the text reception field. good. This allows the customer to edit the text already entered in the text input field and fix the content.

The communication processing unit 18 performs data transmission/reception processing with the operator terminal 2 or the customer terminal 3 via the network NW such as the Internet.

Some of the functions provided by the screen sharing apparatus 10 described above may overlap with functions for realizing online communication, and are not necessarily provided as functions specific to screen sharing.

The operator terminal 2 is a first terminal used by an operator, and is implemented by a smart device such as a so-called personal computer, tablet terminal, or smart phone.
The operator terminal 2 includes at least input/output means for inputting/outputting information such as a display, a mouse, a keyboard, or a touch panel display. Prepare. This web browser is, for example, Google Chrome (registered trademark), Microsoft Edge (registered trademark), Mozilla Firefox (registered trademark), Opera (registered trademark), or the like.

The customer terminal 3 is a second terminal used by the customer, and like the operator terminal 2 is implemented by a smart device such as a so-called personal computer, tablet terminal, or smart phone.
The customer terminal 3 also has input/output means such as a display, a mouse, a keyboard, etc. for inputting/outputting information, and also has a Web browser as a communication processing unit for transmitting/receiving data via the network NW.

In this embodiment, online communication and screen sharing in the online communication are realized by a browser program without installing dedicated software in the operator terminal 2 or the customer terminal 3 . However, even when online communication is executed by dedicated software, screen sharing by the screen sharing apparatus 10 according to the present embodiment can be realized on the online communication.

In addition to the functional units described above, the operator terminal 2 and the customer terminal 3 are appropriately equipped with cameras, microphones, speakers, etc. for executing online communication via video and audio. Accordingly, it has functional units for processing video data and audio data.

●Processing Flow Next, an example of the flow of processing executed by the online communication system 1 will be described with reference to FIGS. 2 to 4. FIG.
First, the online communication between the operator terminal 2 and the customer terminal 3 will be described with reference to FIG.
A session is established between the operator terminal 2 and the customer terminal 3, and online communication starts (S101). Although the mode of establishing a session is not particularly limited, for example, a predetermined URL is issued in response to a request from one of the operator terminal 2 and the customer terminal 3, and the other terminal that has accessed the URL is recognized. to establish a session.

When the screen sharing apparatus 10 receives a screen sharing start request from the operator terminal 2 (S102), the terminal information acquisition unit 11 acquires terminal information including information related to the screen configuration of the customer terminal 3 from the customer terminal 3. (S103).
When requesting the start of screen sharing, the operator designates the screen to be shared in units of application programs, displays, and windows.
Further, in the present embodiment, the terminal information is acquired at the timing of receiving the screen sharing start request, but the terminal information may be acquired at the timing of establishing an online communication session or the like.

In response to the screen sharing start request, the synchronization processing unit 12 generates a predetermined display area on the customer terminal 3, and displays the shared screen displayed on the operator terminal 2 in the predetermined display area. is synchronously displayed as (S104).

Also, at this time, the display control unit 13 converts the screen to be shared on the operator terminal 2 into one corresponding to the screen configuration of the customer terminal 3 .
Specifically, the display control unit 13 refers to the aspect ratio of the screens of the operator terminal 2 and the customer terminal 3 acquired by the terminal information acquisition unit 11, the version of the browser, etc., and selects the shared screen of the customer terminal 3. It is displayed on the operator terminal 2 after being converted according to the aspect ratio of the screen and the version of the browser.

At the start of screen sharing, the operator terminal 2 that requested the screen sharing has the authority to operate the screen to be shared, and the operator conducts business negotiations with the customer while operating the screen to be shared.
Then, when the customer wants the customer to operate the screen to be shared, the operator presses a predetermined menu button or the like to request the screen sharing apparatus 10 to transfer the operation authority (S105).
The screen sharing apparatus 10, which receives the operation authority transfer request from the operator terminal 2, causes the authority setting unit 14 to transfer the operation authority of the shared screen to the customer terminal 3 (S106).

As shown in FIG. 3, when the operation authority is transferred from the operator terminal 2 to the customer terminal 3, the detection processing unit 15 detects the operation performed by the customer on the customer terminal 3 while referring to the shared screen. , the operation information related to the detected operation is acquired (S107).

In response, the reflection processing unit 16 reflects the operation executed on the customer terminal 3 to which the operation authority has been transferred on the shared screen of the operator terminal 2 (S108).
Here, for example, if the operation executed on the customer terminal 3 is a movement of the designated position by the pointing device, the movement of the designated position corresponding to this is reproduced on the shared screen, and if it is pressed at the predetermined designated position, For example, pressing is reproduced at a corresponding predetermined designated position on the shared screen.

On the other hand, in the case where a text input field is provided in the shared screen, when the text input field is specified as a result of reflecting the customer's operation on the shared screen, the detection processing unit 15 puts the text input standby state into a state. It is detected (S109). In response to this, the dialog generation unit 17 generates a text input dialog on the customer terminal 3 (S110).

When the customer enters text into the text entry dialog and the text is sent to the screen sharing device 10 (S111), the reflection processing unit 16 instructs the operator terminal 2 to enter the text into the text entry field. (S112). In response to this, on the operator terminal 2, the text received from the customer is entered in the text entry field.

As described above, while the operation authority for the shared screen is being transferred to the customer terminal 3 (S113), the customer's operation is reflected on the shared screen.

The delegation of the operational authority may be canceled from either the operator terminal 2 or the customer terminal 3. When the delegation of the operational authority is canceled in response to an instruction from either terminal, the operational authority is canceled. Return to the operator terminal 2 (S114).

Even when the operation authority is returned to the operator terminal 2, the screen sharing state is maintained as shown in FIG. 4, and the operator continues this state as necessary (S115).
The screen sharing is ended by the operator who started the screen sharing operation (S116), and when the operator terminal 2 or the customer terminal 3 instructs to end the session (S117), the session ends accordingly (S118). ).

●GUI
An example of screens displayed on the operator terminal 2 and the customer terminal 3 and their transitions in the online communication performed according to the above flow will be described with reference to FIGS. 5 to 8. FIG.

FIG. 5 shows examples of screens of the operator terminal 2 and the customer terminal 3 when the screen sharing function is executed. Here, FIG. 5A shows a shared screen G2 displayed on the operator terminal 2. FIG. On the other hand, FIG. 5B shows a shared screen G3 displayed on the customer terminal 3. As shown in FIG.

The example of FIG. 5 shows a case where the operator shares a web page on the Internet. More specifically, the web page that constitutes the shared screen G2 is a page for web search, and includes a text input field G21 in which search text can be input, and a web page based on the text input in the text input field G21. An execution button G22 is provided for accepting a search execution request. On the other hand, the shared screen G3 also displays a text input field G31 corresponding to the text input field G21 and an execute button G32 corresponding to the execute button G22, but the shared screen G3 is generated based on the shared screen G2. However, it is not possible to directly input data into the text input field G31 or press the execution button G32 on the shared screen G3.

In addition, the shared screen G2 displays a cursor G20 indicating the pointing position of the pointing device of the operator terminal 2, and the shared screen G3 displays a corresponding cursor G30.

Here, for example, when the operator operates the pointing device to move the cursor G20 on the shared screen G2, the customer can confirm how the cursor G30 similarly moves on the shared screen G3.

Further, when the operation authority is transferred from the operator terminal 2 to the customer terminal 3, the customer can operate the shared screen G2 from the customer terminal 3. As a result, while referring to the shared screen G3, the customer can perform operations such as moving the cursor G20 in the shared screen G2 as if moving the cursor G30.

FIG. 6 shows a state in which the text input field G21 is specified on the web page in the shared screen G2 by the customer's operation when the operation authority is transferred from the operator terminal 2 to the customer terminal 3.
As shown in FIG. 6A, when the text input field G21 in the shared screen G2 is specified by the customer's operation, the detection processing unit 15 detects a text input waiting state. In response to this, the dialog generator 17 generates a text input dialog G33 on the customer terminal 3 as shown in FIG. 6(b). The input dialog G33 is preferably displayed near the text input field G31 displayed in the shared screen G3.

The text input dialog G33 includes a text reception field G331 for receiving text input from the customer terminal 3, and a text reception field G331 for confirming the content of the text received by the text reception field G331, and entering the text input field G31 in the shared screen G2. A confirmation button G332 for requesting text input and a cancel button G333 for canceling the input are provided.

FIG. 7(b) shows a state in which the customer has entered text into the text reception field G331 using the keyboard (including the virtual keyboard displayed on the touch panel display) provided in the customer terminal 3, or the like. As shown in FIG. 7A, when the customer has just entered the text into the text entry field G331, the text has not yet been reflected in the text entry field G21.
The customer who has finished entering the text in the text entry field G331 can press the confirmation button G332, thereby requesting the screen sharing device 10 to enter the text in the text entry field G21.

Here, the customer can edit the text entered in the text reception column G331 until the confirmation button G332 is pressed. Therefore, the customer can input the converted text into the text input field G21 by appropriately converting the input text into Chinese characters or the like and pressing the confirm button G332.
FIG. 8A shows a state in which the text received from the text reception field G331 is reflected in the text input field G21. Unlike the text that is reflected in the text input field G21 each time the text is input in the text reception field G331, the text can be edited in the text reception field G331 and then reflected in the text input field G21. Therefore, it is also possible to input kanji characters.

As shown in the screen transition from FIG. 7(b) to FIG. 8(b), in this embodiment, when the enter button G332 in the input dialog G33 is pressed, the input dialog G33 is closed, but not limited to this, a button for closing the input dialog G33 is separately provided, and text is accepted from the input dialog G33 until an operation to close the input dialog G33 is performed, and the confirmation button G332 is pressed. The text may be input in the text input field G21 in response to the request.

According to the screen sharing apparatus 10 according to the present embodiment described above, in screen sharing among a plurality of terminals, it is possible to operate a screen to be shared even from the side of the customer terminal 3 that shares the screen. As a result, instead of the operator, it is possible to have the customer input information such as a password and personal information that only the customer knows into the shared screen. It is also possible to ask the customer to confirm the contract or the like displayed on the web by the customer's operation.

In addition, since the screen to be shared and the screen to be shared are adjusted according to the aspect ratio, browser program, etc., the operations performed by the customer while viewing the shared screen on the customer terminal 3 are appropriately reflected on the screen to be shared. .
In addition, since the customer can enter the text edited appropriately by the customer in the text entry field in the shared screen, it is possible to enter appropriate and diverse texts.

In the present embodiment described above, it is assumed that an operator and a customer are negotiating business. , the screen sharing device 10 according to the present embodiment can be applied.

In addition, the display control unit 13 converts the screen to be shared on the operator terminal 2 into one corresponding to the screen configuration of the customer terminal 3 and displays it on the screen of the operator terminal 2. It is also possible to convert the shared screen on 3 into one corresponding to the screen configuration of the operator terminal 2 and display it on the screen of the customer terminal 3 .

Also, the number of terminals that perform screen sharing is not particularly limited, and the present invention can be applied among three or more terminals. When screen sharing is performed between three or more terminals in this way, in transferring the operation authority of the screen to be shared, the terminal requesting the transfer of the operation authority specifies the terminal to which the operation authority is transferred. It should be
