Of course, it is also possible to add on the screen after display. The handwritten memo and the sticky memo displayed on the mobile terminal 4 can be freely updated, deleted, moved, and connected to each other by connecting them with a straight line.

  In addition, the instructor or administrator can register in advance the management server 3 with materials that are frequently used in group discussions, such as fishbone diagrams (characteristic factor diagrams) and Venn diagrams. A participant can add a pre-registered fish bone diagram (characteristic factor diagram) or the like to the group discussion document 11 by pressing the template import button 46 shown in FIG. It is. It is added to the last page of the group discussion material 11 and, like the group discussion material 11 before the addition, handwritten memos, sticky memos and the like can be superimposed and entered.

[Save notes to group discussion materials]
Participants may want to write comments or the like on the displayed group discussion material as the group discussion proceeds or is discussed. In such a case, it is possible to input a note or the like on the screen of the mobile terminal 4 that is being used by the participant. The input memo creates memo data 12 as data different from the group discussion material 11, and the portable terminal 4 holds the memo data 12.

  The group discussion material 11 is not newly generated during the group discussion, and the same group discussion material 11 is used from the start to the end. The group discussion material 11 is displayed in a form in which the memo data 12 entered by the participants of each group is sequentially superimposed during the group discussion.

  Here, the participant presses the “SAVE” button 41 on the screen to transmit the memo data 12 held by the portable terminal 4 to the management server 3, and the management server 3 stores the memo data 12. The mobile terminal 4 and the discussion management terminal 5 belonging to the group periodically check the contents of the memo data 12 stored in the management server 3 and refer to the updated memo data 12 when an update occurs. Then, the memo data 12 is redrawn in a form superimposed on the group discussion material 11 of the group. In this way, the same group discussion material 11 can be displayed on the screens of the portable terminals 4 and discussion management terminals 5 of other participants belonging to the same group.

  When the “SAVE” button 41 is not pressed, the memo data 12 is stored at the end of the group discussion, when the portable terminal 4 is turned off, any operation of the user of the portable terminal 4, or the management server 3 or discussion management. It is erased from the portable terminal 4 without being saved by a command from the terminal 5 for the use.

  All the participants belonging to the group can press the “SAVE” button 41, and the memo data 12 for the discussion material information of the group is written and updated one after another by the memo data 12 of a plurality of persons. Become.

  Further, the plurality of memo data 12 stored as the change history may be set so as to be browseable by the portable terminal 4 and the discussion management terminal 5. This is useful for reviewing group discussions.

[Function of terminal for discussion management during group discussion]
FIG. 5A and FIG. 5B are diagrams illustrating the discussion management terminal 5 during a group discussion. The discussion management terminal 5 can simultaneously browse a plurality of group discussion materials 11 created by each group during the group discussion. For example, as shown in FIG. 5 (A), the display unit of the discussion management terminal 5 is divided to display one or a plurality of group discussion materials 11a to 11d, or as shown in FIG. 5 (B). When a single group discussion material 11 is displayed in a large size and the other group discussion materials 11a to 11d are displayed in a small size (for example, tabs, icons, etc.) for browsing, the tab It is preferable that the corresponding group discussion material 11 is expanded by manipulating the icons and the like.

  When the group discussion materials 11a to 11d displayed on the discussion management terminal 5 are updated, the group discussion materials 11a to 11d displayed on the discussion management terminal 5 are also updated as needed. As the discussion proceeds, it is possible to check the state in which writing is added to the group discussion materials 11a to 11d as needed.

  Further, the discussion management terminal 5 has an access right that allows writing to each group discussion material 11a to 11d being created by each group during the group discussion. Therefore, it is possible to guide the progress of the group discussion smoothly by suggesting the direction of the group discussion, such as writing advice during the group discussion, pointing out with a pointer, and pointing out mistakes. it can.

[Change grouping]
In addition, during group discussions, participants can change their own group. During the lecture, the group selection screen 25 shown in FIG. 9 is displayed from the discussion management terminal 5, and the group name to be newly joined can be tapped (clicked) to join the corresponding group. For example, a participant can participate in a group discussion by changing the group A to a group A for the first group discussion, a group C for the second session, and a group B for the third session. Also, a group change button 42 shown in FIG. 4 is pressed to display a list of groups to which the participant can join, and the group can be changed by the participant selecting.

  However, since only the groups registered in advance by the lecturer or administrator in the new lecture information creation screen-new group creation-24e (shown in FIG. 8E) are displayed in the group list, Only movement between permitted groups is possible.

  In addition, when participating in a new group discussion, only the group discussion material 11 can be accessed. For example, the first group discussion during the lecture will participate in the A group and can access only the group discussion material 11a, but the second time, when the C group will participate, only the group discussion material 11c can be accessed. Thus, it becomes impossible to access the group discussion material 11a that was previously accessed.

  Further, when no group discussion is held, all the group discussion materials 11 cannot be accessed.

  When a new group is to be created, the administrator or instructor uses the management server 3 to input a group-new creation screen-24e shown in FIG. 8E and create a new group. I can do it.

[Announcement of group discussion]
In the case of the entire presentation after the group discussion, the participant requests the presenter authority from the lecturer, and the lecturer “permits” the presenter on the presenter authority grant screen 47 on the discussion management terminal 5. This is done by approving the temporary presenter authority to the participant.

  Participants with temporary presenter authority use the presentation terminal 6 in front of all the participants, and use the same discussion data 11 and memo data for the discussion management terminal 5 and all portable terminals 4. 12 can be displayed, an announcement can be made, and the results of the group discussion can be verified. At this time, if a large touch panel is registered as one participant, the screen of the presenter's terminal is displayed on the large display, which is easy for everyone to see.

[Instructions for page feed during presentation]
When the presentation is started, the presenter displays the group discussion material 11 and the memo data 12 displayed on the presentation terminal 6 in accordance with the progress of the presentation in FIG. 4 displayed on the presentation terminal 6. Show page feed button 48
Operate to turn the page. The presentation terminal 6 transmits a “page feed” command to the management server 3 when page feed is performed. The management server 3 receives the command and transfers a “page feed” command to the portable terminal 4 and the discussion management terminal 5. When the portable terminal 4 and the discussion management terminal 5 receive the command, the page of the group discussion material 11 and the memo data 12 are displayed so as to be the page described in the command, and the presentation terminal 6 and the portable terminal 4 The group discussion material 11 and the memo data 12 of the terminal 4 and the discussion management terminal 5 are synchronized and display the same page.

  During the group discussion, the participant can change the operation method to “manual operation”, and thereby the group discussion material 11 displayed on the portable terminal 4 can be changed to an arbitrary page of the participant. When an “page advance” command is received from the presentation terminal 6 during “manual operation”, if an arbitrary page is displayed, the command may be ignored and synchronization may not be performed. If there are a plurality of group discussion materials 11 and memo data 12, other materials can be browsed.

  The portable terminal 4 is provided with a “synchronization” button (not shown), and when pressed, the group discussion material 11 and the memo data 12 of the presentation terminal 6 can be synchronized with the display page. . At this time, the operation method is switched to “automatic operation”. Further, a button such as “forced synchronization” may be provided on the discussion management terminal 5 and the pages of all the mobile terminals 4 may be forcibly synchronized by pressing the button.

In addition, the permission order of the temporary presenter is arbitrarily determined by, for example, the order of application. Therefore, the order in which the group discussion materials 11 are announced is also determined by the presentation order of the temporary presenters.
[End of group discussion]
To end the group discussion, the lecturer and the participant can press the “group discussion end” button (not shown) on the screen of his / her mobile terminal 4 so that the person who has pressed the group discussion can leave the group discussion.
