If the guide information has been saved, the guide information display unit 43 proceeds to step S12, and determines whether or not the conference state is resting. If the state of the meeting is resting, the guidance information display unit 43 proceeds to step S13 and determines whether or not the sharing mode is set. If it is a sharing mode, the guidance information display part 43 will progress to step S14 and will display guidance information.

  On the other hand, if the guide information has not been saved in step S11, the conference state is not resting in step S12, or the sharing mode is not in step S13, the conference material display unit 45 proceeds to step S15 and displays the conference material. .

  That is, the participation terminal 13 that has already participated in the conference in which the guide information is registered displays the guide information when the conference state is resting and in the sharing mode. In addition, the participation terminal 13 that has already participated in the conference in which the guide information is registered displays the conference material when the conference state is being held. Even if the conference state is resting, the participating terminal 13 that has already participated in the conference in which the guide information is registered displays the conference material in the personal mode.

  FIG. 10 is a sequence diagram of an example of display processing of conference material and guidance information. FIG. 10 is a sequence diagram illustrating an example of communication between the conference server device 11 and the participation terminal 13 when participating in a conference. After a conference to be held or participated in by a conference presenter or participant is selected, processing of a sequence diagram as shown in FIG. 10 is started.

  The transmission request unit 41 of the participating terminal 13 proceeds to step S21 and requests the conference server apparatus 11 to transmit guidance information. In step S <b> 22, the material transmission unit 33 of the conference server device 11 accepts a guide information transmission request from the participating terminal 13. In step S <b> 23, the material transmission unit 33 transmits guidance information to the participating terminals 13. In step S <b> 24, the guidance information display unit 43 of the participating terminal 13 displays the guidance information acquired from the conference server device 11 because the conference state is resting. The guide information storage unit 42 stores the guide information acquired from the conference server device 11.

The conference material storage unit 44 stores the conference material acquired from the conference server device 11.

  In step S <b> 28, the conference state confirmation unit 46 of the participating terminal 13 confirms the conference state (resting / held) with the conference server device 11. The conference control unit 35 of the conference server device 11 accepts confirmation of the conference status from the participating terminal 13. In step S <b> 30, the conference control unit 35 of the conference server device 11 transmits the conference status to the participating terminal 13. In step S31, the guidance information display unit 43 of the participating terminal 13 displays guidance information when the conference state is resting. Further, the conference material display unit 45 of the participating terminal 13 displays the conference material when the conference state is being held.

  FIG. 11 is a diagram illustrating an example of a relationship between a conference state and requestable operations. FIG. 11 shows operations that can be requested from the participating terminal 13 to the conference server device 11 when the conference state is not held, is being held, or is taking a break.

  When the state of the conference is not held, the participating terminal 13 can make a holding request to the conference server device 11. The participating terminal 13 that has requested to hold an unheld conference becomes a presenter terminal operated by the presenter.

  When the conference state is being held, the participation terminal 13 makes a participation request, an exit request, a break request, a conference end request, a conference progress request, a presentation right acquisition request, and a sharing / personal mode switching request to the conference server device 11. Can do. The break request, the conference end request, and the conference progress request are operations that can be requested from the presenter terminal. When the conference state is resting, the participation terminal 13 can make a participation request, an exit request, a break end request, a conference end request, and a sharing / personal mode switching request to the conference server device 11. The break end request and the conference end request are operations that can be requested from the presenter terminal.

  The conference registered from the registration terminal 10 has a status of “Not held”. A conference whose guidance information is registered and whose conference state is “not held” receives a request for holding from the participation terminal 13, and the conference state is “resting”.

  When there is a participation request from the participation terminal 13 in a conference whose conference state is “breaking”, the conference server device 11 first transmits guidance information. Guidance information is displayed on the participating terminals 13. After transmitting the guide information, the conference server device 11 transmits the conference material.

  If there is a break end request from the presenter terminal in a conference whose conference state is “breaking”, the conference server apparatus 11 changes the conference state to “in progress”. The participating terminal 13 in the sharing mode displays the conference material. The presenter terminal can make a conference progress request for a conference whose conference status is “in progress”.

  FIG. 12 is an image diagram showing an example of the state transition of the conference. In the conference system 1 according to the present embodiment, the conference state transitions as shown in FIG. A meeting whose state is “not held” transitions to the state “resting” when a holding request is received from the participation terminal 13. The conference whose state is “resting” transitions to the state “currently being held” when a break end request is received from the participating terminal 13.

  A meeting whose state is “in progress” transitions to the state “resting” when a break request is received from the participating terminal 13. A conference whose state is “breaking” or “currently being held” transitions to the state “not held” when a conference end request is received from the participation terminal 13. In addition, a meeting whose state is “breaking” or “currently being held” receives a participation request from the participation terminal 13.

  FIG. 13 is an image diagram of an example of a conference screen. Participating terminal 13 accepts a break request or break end request instruction from the presenter from conference screen 1000 as shown in FIG. On the conference screen 1000, guidance information and conference materials are displayed. The presenter of the conference presses the exit button 1001 on the conference screen 1000 to open the exit menu, and issues a break request or a break end request instruction.

  FIG. 14 is an image diagram illustrating an example of instructions for a break start and a break end. When the exit button 1001 is pressed during the break of the conference, an exit menu 1010 is displayed on the conference screen 1000. The exit menu 1010 includes a “break end” menu. The presenter can make a break end request by selecting the “end break” menu from the exit menu 1010. When the “break end” menu is selected from the exit menu 1010, a break end confirmation screen 1011 is displayed on the conference screen 1000. By depressing a “conference start” button included in the break end confirmation screen 1011, the presenter can transition the conference state from resting to holding. The guidance information displayed on the conference screen 1000 is switched to the conference material.

  When the exit button 1001 is pressed during the holding of the conference, an exit menu 1020 is displayed on the conference screen 1000. The exit menu 1020 includes a “break start” menu. The presenter can make a break request by selecting a “break start” menu from the exit menu 1020.

  When the “break start” menu is selected from the exit menu 1020, a break start confirmation screen 1021 is displayed on the conference screen 1000. By depressing a conference break button included in the break start confirmation screen 1021, the presenter can transition the conference state from holding to resting. The conference material displayed on the conference screen 1000 is switched to guidance information.

  Further, by pressing a conference break (countdown) button included in the break start confirmation screen 1021, the presenter can change the conference state from being held to being resting. A countdown designation screen 1022 is displayed on the conference screen 1000. On the countdown designation screen 1022, the end time of the break can be set. Then, by depressing a conference break (countdown) button on the countdown designation screen 1022, the presenter can change the conference state from holding to resting. The conference material displayed on the conference screen 1000 is switched to guidance information. In the guidance information, a clock that counts down to the end time of the break is displayed.

  FIG. 15 is a flowchart of an example of the countdown display process. In step S51, the participation terminal 13 which is the presenter terminal sets the end time of the break from the countdown designation screen 1022 in FIG. In step S <b> 52, the presenter terminal transmits a break end time to the conference server device 11.

  In step S <b> 53, the conference server device 11 calculates the time until the end time of the break and transmits it to each participating terminal 13. In step S54, each participating terminal 13 counts down the time until the end time of the break received from the conference server device 11 on the guidance information as shown in FIG. 16, for example. FIG. 16 is an image diagram of an example of a break screen. A time “5 minutes 25 seconds” until the end time of the break is displayed on the during-break screen 1100 in FIG.

  In step S55, the conference server apparatus 11 notifies each participating terminal 13 of the end of the break at the end time of the break. In step S56, each participating terminal 13 sets the time until the end time of the break displayed on the guidance information as “0 minute 0 second”.

  In the flowchart of FIG. 15, the time of the conference server device 11 is displayed on the countdown designation screen 1022 of FIG. 14 so as not to be affected by the clock deviation of each participating terminal 13. In addition, after the conference server apparatus 11 transmits the time until the end time of the break to each participating terminal 13, each participating terminal 13 individually counts down to the end time of the break. The conference server device 11 adjusts the break end time so as not to shift by notifying each participating terminal 13 of the end of the break at the break end time.

<Summary>
According to the present embodiment, since it is possible to display guidance information other than the conference material to be displayed during the conference at a time such as a break other than during the conference, the conference is being held other than during the conference. It does not give the participants an image as if they were. In other words, the conference system 1 according to the present embodiment can clearly notify the participant that the conference is in a break.

  Further, according to the present embodiment, before the conference material is downloaded from the conference server device 11 to the participation terminal 13, the guide information having a data capacity smaller than that of the conference material is downloaded and displayed. The participating terminal 13 downloads the conference material behind the guidance information, thereby reducing the waiting time for downloading the conference material.

  The present invention is not limited to the specifically disclosed embodiments, and various modifications and changes can be made without departing from the scope of the claims. For example, in the present embodiment, a conference system is shown as an example of a screen sharing system, but the present invention can also be applied to a system for sharing and displaying information such as a seminar system and an education system.

  For example, the conference server device 11 is an example of an information processing device. The participating terminal 13 is an example of a terminal device. The transmission request unit 41 is an example of a data acquisition unit. The guidance information display unit 43 is an example of a first display unit. The meeting material display unit 45 is an example of a second display unit. The conference material is an example of target content. Guidance information is an example of other content. The target content may be an image corresponding to the screen of the participating terminal 13.

  Note that the conference system 1 having the registration terminal 10, the conference server device 11, and the participation terminal 13 is an example, and it goes without saying that there are various system configuration examples depending on applications and purposes.
