[Outline of this embodiment]
In this embodiment, in such an electronic conference system, the master terminal 10 transmits operation information (hereinafter referred to as “master operation information”) at the master terminal 10 to the slave terminal 30 via the server 50, It is assumed that the screens of the plurality of slave terminals 30 (hereinafter referred to as “slave screens”) are synchronized with the screen of the master terminal 10 (hereinafter referred to as “master screen”). In this specification, “synchronizing” the slave screen with the master screen means that the content displayed on the slave screen is the same as the content displayed on the master screen.

  However, in the present embodiment, the slave terminal 30 can perform not only the synchronized state in which the slave screen is synchronized with the master screen, but also an asynchronous state in which the synchronized state is released or a certain amount of operation while remaining in the synchronized state. Possible semi-synchronized states are possible. Among these, the asynchronous state refers to a state in which operations such as page movement, text writing, and graphic drawing can be performed at the slave terminal 30 and the synchronous state is not set by the master operation information. The semi-synchronized state refers to a state where the slave terminal 30 can perform operations such as page movement, text writing, and graphic drawing, but may be in a synchronized state depending on master operation information.

  Under this assumption, in the present embodiment, as a basic example, the slave terminal 30 includes state information indicating whether the slave terminals 30 are in a synchronous state, an asynchronous state, or a semi-synchronous state, The server 50 is notified of the operation information (hereinafter referred to as “slave operation information”). Then, the master terminal 10 displays the status information notified to the server 50, or constructs and displays a slave screen using the slave operation information notified to the server 50. Here, the synchronous state is an example of the first state in which the display content of the first display device is reflected in the display content of the second display device, and the asynchronous state is the display content of the first display device. Is an example of the second state that is not reflected in the display content of the second display device and is not reflected. In the semi-synchronized state, the display content of the first display device is the same as that of the second display device. It is an example of the 3rd state which is not reflected in display content but may be reflected.

  FIG. 3 is a diagram showing a display screen 210 which is a first screen example for displaying a slave screen on the master terminal 10. The display screen 210 includes a master screen operation area 211 for operating the master screen, and a master screen operation icon display area 212 for displaying icons used for performing operations on the master screen. Further, it includes a slave screen display area 213 for displaying a slave screen and a slave screen forcible operation icon display area 214 for displaying an icon used for performing a forced operation on the slave screen. Further, a status information display area 215 for displaying status information of each slave terminal 30 is included. Here, the state information may be represented by characters, figures, symbols, etc., which are examples of signs. In this display screen 210, when it is desired to refer to the screen of a certain slave terminal 30, the slave terminal 30 is selected using the slave operation information notified to the server 50 by selecting the slave terminal 30 in the status information display area 215. Are constructed and displayed in the slave screen display area 213. For example, in the figure, since slave terminal # 3 is selected as shown by being surrounded by a thick line, the screen of slave terminal # 3 is displayed in slave screen display area 213.

  3 includes a master screen operation area 211, a master screen operation icon display area 212, a slave screen display area 213, a slave screen forced operation icon display area 214, and a status information display area 215. However, this is not a limitation. The master terminal 10 receives only status information, and the display screen 210 may include only the status information display area 215 in addition to the master screen operation area 211 and the master screen operation icon display area 212. That is, the master terminal 10 may not receive the slave operation information, and the display screen 210 may not include the slave screen display area 213 and the slave screen forced operation icon display area 214.

FIG. 4 is a diagram showing a display screen 220 as a second screen example for displaying a slave screen on the master terminal 10. The display screen 220 includes divided display areas 221 _{1 to} 221 ₂₀ for displaying a slave screen. For example, the divided display areas 221 _N, it is preferable to display the screen of the slave terminal #N. One of the divided display areas 221 _{1 to} 221 ₂₀ is used for displaying the screen of the master terminal 10, and the remaining 19 are used for displaying the screen of the slave terminal 30. Also good.

  Moreover, in this Embodiment, you may instruct | indicate the master terminal 10 to change the state of a certain slave terminal 30 as a 1st modification. For example, when the master confirms that there is a slave terminal 30 that is not in synchronization in the status information display area 215 shown in FIG. 3, the part corresponding to the slave terminal 30 is selected in the status information display area 215. Thus, it is conceivable to perform forced synchronization to force the slave terminal 30 into a synchronized state.

  Furthermore, in the present embodiment, as a second modification, the master terminal 10 may display the displayed slave screen on all other slave terminals 30. This is because the master may want to share the contents displayed on the screen of a slave terminal 30 among the plurality of slave terminals 30 among all the slave terminals 30. Here, the slave terminal 30 on which the content to be shared is displayed on the screen may be specified by selecting a portion corresponding to the slave terminal 30 on the status information display area 215 shown in FIG. 3, for example.

  Furthermore, in the present embodiment, as a third modification, the master terminal 10 may display a screen that will be displayed on the slave terminal 30 by an operation on the master terminal 10. This responds to a request that the master wants to confirm what screen is actually displayed on the slave terminal 30 by his operation. However, this screen is not shown in FIGS.

[Functional configuration of electronic conference system]
FIG. 5 is a block diagram showing an example of the functional configuration of each device constituting the electronic conference system according to the present embodiment. As illustrated, the electronic conference system in the present embodiment includes a master terminal 10, a slave terminal 30, and a server 50. As described above, there may be two or more slave terminals 30, but only one is shown here.

  First, a functional configuration example of the master terminal 10 will be described. As illustrated, the master terminal 10 includes a transmission unit 21, a reception unit 22, an operation reception unit 23, a display control unit 24, and a screen construction unit 25.

  The transmission unit 21 transmits the material ID to the server 50 when displaying the material on the master screen. Further, when an operation is performed on the material displayed on the master screen, master operation information indicating the content of the operation is transmitted to the server 50. Further, when an operation for instructing a change in the state of a certain slave terminal 30 is performed, an instruction to change the state of the slave terminal 30 is transmitted to the server 50. This state change instruction includes information on the slave terminal 30 whose state is to be changed and state change information indicating the contents of the state change. Among these, as status change information, forcible synchronization information indicating forced synchronization and forced operation information indicating the content of forced operation that is an operation forcibly performed on the material displayed on the slave screen are conceivable. Here, the forced operation may be an operation of moving to a specific page, or may be a fine operation such as writing with a pen tool. Furthermore, when an operation for instructing sharing of a screen of a certain slave terminal is performed, the slave operation information of the slave terminal, not the master operation information, is extracted from the screen construction unit 25 and transmitted to the server 50. In the present embodiment, master operation information is used as an example of the first operation information, and the transmission unit 21 is provided as an example of a transmission unit that transmits the first operation information. Further, as an example of the third operation information, slave operation information of a slave terminal displaying a screen to be shared is used.

  The receiving unit 22 receives the material from the server 50 when displaying the material on the master screen. Further, after the document is displayed on the slave screen, the server information indicating the slave terminal 30, the status information indicating the status of the slave terminal 30, and the slave operation information indicating the content of the operation at the slave terminal 30 are stored in the server. Receive from 50. Among these, the terminal information is information for identifying the slave terminal 30. As such information, a terminal number is exemplified, but information on a user who operates the slave terminal 30 may be used. The state information is information indicating, for example, whether the slave terminal 30 is in a synchronous state, an asynchronous state, or a semi-synchronous state. Alternatively, it may be further subdivided so that it is operating in a fully synchronized state or a semi-synchronized state, operating in an asynchronous state, or in an asynchronous state but no operation. Slave operation information is used to reproduce the slave screen, such as the document ID of the displayed document, the page number of the displayed document, and the coordinate information of characters and figures when the document page is drawn with a pen tool. Information. At that time, the receiving unit 22 also passes this slave operation information to the screen construction unit 25. In the present embodiment, slave operation information is used as an example of the second operation information, and the receiving unit 22 is provided as an example of a receiving unit that receives the second operation information.

  The operation accepting unit 23 accepts an operation for designating the material ID when displaying the material on the master screen. Further, after the material is displayed on the master screen, an operation for the material is accepted. At that time, the operation receiving unit 23 also passes master operation information indicating the contents of this operation to the screen construction unit 25. When a list of terminal information and status information of the slave terminal 30 is displayed, an operation for selecting the slave terminal 30 from the list is accepted. Furthermore, an operation for instructing a change in the state of a certain slave terminal 30 is accepted. Furthermore, an operation for instructing sharing of the screen of a certain slave terminal is accepted.

  The display control unit 24 controls the display device 15 to display the material when displaying the material on the master screen. Further, when the receiving unit 22 receives terminal information, status information, and slave operation information from the server 50, the display device 15 is controlled to display a list of terminal information and status information. At this time, if the received slave operation information is the same as the transmitted master operation information, the display control unit 24 determines that the slave terminal 30 is in a synchronized state, and the received slave operation information includes the transmitted master operation information and the master operation information. If they are different, it may be determined that the slave terminal 30 is in an asynchronous state. When information on any slave terminal 30 is selected from the list, the screen construction unit 25 displays the screen of the slave terminal 30 constructed using the slave operation information. The device 15 is controlled. At that time, the slave screen may not be displayed in the case of complete synchronization or complete asynchronous. Further, when an operation is performed on the material displayed on the master screen, the screen construction unit 25 does not display the slave screen constructed using the slave operation information, but the screen construction unit 25 displays the master screen. The display device 15 is controlled to display a slave screen constructed using the operation information. At this time, the slave screen may be displayed by the same method as that displayed on the slave terminal 30. In the present embodiment, state information or a slave screen representing the state of the slave terminal 30 is used as an example of notification information, and a display control unit 24 is provided as an example of a control unit that controls to display the notification information. ing.

  When information for any slave terminal 30 is selected from the list of terminal information and status information, the screen construction unit 25 displays the slave screen based on the master screen and the slave operation information of the slave terminal 30. To construct. At that time, in the case of complete synchronization or complete asynchronous, it is not necessary to construct a slave screen. When an operation is performed on the material displayed on the master screen, a slave screen is constructed based on the master screen and the master operation information.

  Next, a functional configuration example of the slave terminal 30 will be described. As illustrated, the slave terminal 30 includes a transmission unit 41, a reception unit 42, an operation reception unit 43, and a display control unit 44.

  After the document is displayed on the slave screen, the transmission unit 41 includes terminal information indicating the slave terminal 30, state information indicating the state of the slave terminal 30, slave operation information indicating the content of the operation at the slave terminal 30, and Is transmitted to the server 50. Since terminal information, status information, and slave operation information have already been described, description thereof will be omitted here.

  The receiving unit 42 receives the material from the server 50 when the material is displayed on the master screen. Further, when an operation is performed on the material displayed on the master screen, master operation information indicating the content of the operation is received from the server 50. Further, when an operation for instructing a change in the state of a certain slave terminal 30 is performed, an instruction to change the state of the slave terminal 30 is received from the server 50. Since this state change instruction has already been described, description thereof is omitted here. Furthermore, when an operation for instructing the screen sharing of a certain slave terminal is performed, the slave operation information of the slave terminal is received from the server 50 instead of the master operation information.

  The operation receiving unit 43 receives an operation on the material after the material is displayed on the slave screen. Also, a state information change operation for changing state information indicating whether it is in a synchronous state, an asynchronous state, or a semi-synchronous state is accepted. Here, the state information changing operation may be performed, for example, by pressing a button corresponding to a synchronous state, an asynchronous state, or a semi-synchronous state. Alternatively, the default is the synchronous state, the synchronous state is maintained by performing no operation, the asynchronous state is changed by pressing the button for changing to the asynchronous state, and operations on the material displayed on the slave screen are performed. It may be changed to a semi-synchronized state. In this sense, it can be said that the state information is determined using the second operation information.

  The display control unit 44 controls the display device 35 to display the material when the material is displayed on the master screen. Further, when an operation is performed on the material displayed on the master screen, the slave screen is synchronized with the master screen by reflecting the master operation information on the material displayed on the slave screen. Further, when an operation for instructing the change of the own state is performed, the own state is changed. For example, when the receiving unit 42 receives the forced operation information for the material displayed on the slave screen, the screen reflecting the operation content indicated by the forced operation information on the slave screen is displayed. In addition, after displaying the warning screen that warns about reflecting the operation content indicated by the forced operation information on the slave screen, the screen reflecting the operation content indicated by the forced operation information on the slave screen may be displayed. It is also possible to just display a warning screen or the like. In the present embodiment, the display control unit 44 is provided as an example of reflecting means for reflecting the display content of the first display device to the display content of the second display device.

  Next, a functional configuration example of the server 50 will be described. As illustrated, the server 50 includes a transmission unit 61, a reception unit 62, a material storage unit 65, and a material management unit 66.

  The transmission unit 61 transmits the material to the master terminal 10 when displaying the material on the master screen. After the material is displayed on the slave screen, the terminal information indicating the slave terminal 30, the state information indicating the state of the slave terminal 30, and the slave operation information indicating the content of the operation at the slave terminal 30 are stored in the master. Transmit to the terminal 10. Since terminal information, status information, and slave operation information have already been described, description thereof will be omitted here.

  In addition, the transmission unit 61 transmits the material to the slave terminal 30 when displaying the material on the slave screen. Further, when an operation is performed on the material displayed on the master screen, master operation information indicating the content of the operation is transmitted to the slave terminal 30. Further, when an operation for instructing a change in the state of a certain slave terminal 30 is performed, an instruction to change the state of the slave terminal 30 is transmitted to the slave terminal 30. Since this state change instruction has already been described, description thereof is omitted here. Furthermore, when an operation for instructing the screen sharing of a certain slave terminal is performed, the slave operation information of the slave terminal is transmitted to the slave terminal 30 instead of the master operation information.

  The receiving unit 62 receives the material ID from the master terminal 10 when displaying the material on the master screen. Further, when an operation is performed on the material displayed on the master screen, master operation information indicating the content of the operation is received from the master terminal 10. Further, when an operation for instructing a change in the state of a certain slave terminal 30 is performed, an instruction to change the state of the slave terminal 30 is received from the master terminal 10. Since this state change instruction has already been described, description thereof is omitted here. Furthermore, when an operation for instructing the screen sharing of a certain slave terminal is performed, the slave operation information of the slave terminal is received from the master terminal 10 instead of the master operation information.

  In addition, after the document is displayed on the slave screen, the receiving unit 62 displays the terminal information indicating the slave terminal 30, the state information indicating the state of the slave terminal 30, and the slave indicating the content of the operation at the slave terminal 30. Operation information is received from the slave terminal 30.

  As shown in the figure, when the master terminal 10 performs a forced operation on the slave terminal 30, first, the operation receiving unit 23 receives a forced operation on the material on the slave screen displayed on the master terminal 10 (step 121). Here, for example, the slave terminal 30 having the slave screen displayed in the slave screen display area 213 of FIG. 3 is forcibly operated using the icon displayed in the slave screen forced operation icon display area 214 of FIG. Are subject to forced operation. When the forced operation is accepted in step 121, the transmission unit 21 transmits forced operation information indicating the content of the forced operation to the slave terminal 30 that is the target of the forced operation (step 122).

  Thereby, in the slave terminal 30, the receiving part 42 receives forced operation information from the master terminal 10 (step 321). Then, the display control unit 44 controls the display device 35 so as to display the content of the forced operation indicated by the forced operation information on the material on the slave screen (step 322).

  When the master terminal 10 instructs the slave terminal 30 to share the screen of another slave terminal, first, the operation reception unit 23 selects the slave terminal displaying the screen to be shared. Accept (step 123). This may be performed, for example, by selecting a slave terminal displaying a screen to be shared from the list shown in the state information display area 215 of FIG. When the selection of the slave terminal is accepted in step 123, the transmission unit 21 transmits the slave operation information of the slave terminal that has already been received by the reception unit 22 and stored in the screen construction unit 25 to the slave terminal 30 (step). 124).

  Thereby, in the slave terminal 30, the receiving part 42 receives slave operation information from the master terminal 10 (step 323). Then, the display control unit 44 controls the display device 35 so as to display the content of the operation indicated by the slave operation information on the material on the slave screen (step 324).
