The storage unit 303 may be provided outside the server 30 and connected to the server 30 via the communication network 20.

  Hereinafter, a specific configuration of the electronic conference system 100 will be described, mainly focusing on the presenter terminal 10a and the participant terminal 10b.

  FIG. 3 is a functional block diagram showing a specific configuration of the participant terminal 10b. The participant terminal 10b includes a presenter operation reception unit 11, a participant operation acquisition unit 12, an operation type determination unit 13, a synchronization determination unit 14, and a display control unit 15. These elements are realized by the CPU 101 executing a program stored in the memory 102 (see FIG. 2).

After transmitting the program and the material data, the server 30 mainly functions as a repeater for performing information communication between the presenter terminal 10a and the participant terminals 10b, 10c, and 10d. The operation terminal 10 on which the program has been downloaded or recorded functions as an information processing device. The computer from which the program has been downloaded may be the operation terminal 10 or the server 30.

  Each function corresponding to the above program will be described.

  The presenter operation receiving unit 11 receives, from the presenter terminal 10a, information indicating the content of the presenter's operation on the presenter terminal 10a (hereinafter, presenter operation information) (second operation content). The presenter operation information includes, for example, operations such as displaying a new material, writing to the material with a pen tool (handwriting tool), picking up (selecting) a posted comment, switching the material page, inputting and moving a mouse pointer, and voice input. This is information indicating the content.

  Here, a specific example of the processing content in the presenter terminal 10a will be described. FIG. 5 shows an example of display contents displayed on the display screen of the presenter terminal 10a.

  For example, when the presenter operates a mouse or the like (input unit 105) on the presenter terminal 10a to read materials stored in the media DB 31 (operation for displaying new materials on the material screen), The presenter terminal 10a notifies (transmits), via the communication unit 104, presenter operation information indicating the above-described operation content including information indicating the material storage destination URL or the material ID to the participant terminal 10b.

  Further, for example, when the presenter operates the mouse on the presenter terminal 10a to input a mouse pointer on the document screen (see FIG. 5) displayed on the display unit 106, the presenter terminal 10a The participant terminal 10b is notified of the presenter operation information indicating the operation contents including the information indicating the position (coordinates) of the mouse pointer, the ID of the input material, the page number, and the like via the unit 104. Note that the presenter terminal 10a may sequentially transmit presenter operation information at regular intervals (for example, every 50 msec).

  Further, for example, when the presenter operates the pen tool on the presenter terminal 10a to write characters and the like on the material screen (see FIG. 5) displayed on the display unit 106, the presenter terminal 10a The participant terminal 10b is notified of the presenter operation information indicating the operation contents including the information indicating the written position (coordinate), the ID of the written material, the page number, and the like via the unit 104.

  For example, when the presenter operates the mouse on the presenter terminal 10a to switch the page of the material screen (see FIG. 5) displayed on the display unit 106, the presenter terminal 10a Via 104, presenter operation information indicating the operation content including the information indicating the ID of the displayed material and the designated page number is notified to the participant terminal 10b.

  In this manner, the presenter terminal 10a notifies each participant terminal 10b, 10c, 10d of information indicating the content based on the presenter's operation.

  The participant operation acquisition unit 12 acquires information (hereinafter, referred to as participant operation information) (first operation content) indicating the content operated by the participant on the participant terminal 10b. The participant operation information is the same as the presenter operation information. For example, the operation contents such as display of a material, writing to the material with a pen tool, creation of a posted comment, page switching of the material, input and movement of a mouse pointer, voice input, etc. This is the information to be shown.

  The operation type determination unit 13 determines an operation type (presenter operation type) based on the presenter operation information received by the presenter operation reception unit 11 from the presenter terminal 10a. Further, the operation type determination unit 13 determines the operation type (participant operation type) based on the participant operation information acquired by the participant operation acquisition unit 12 at the own terminal (participant terminal 10b). The operation type is obtained by classifying the operation contents of the presenter and the participants by type. The operation type is set in advance, and is stored in the storage unit 103 as, for example, an operation type table. The operation contents registered in the operation type table change important operation contents for the presenter and the participant, for example, display contents (synchronous contents) displayed on the participant terminal 10b in synchronization with the presenter terminal 10a. The operation to be performed. Specifically, when the first page of the material A displayed on the presenter terminal 10a is synchronously displayed on the participant terminal 10b, by switching to the second page, the participant terminal 10b The mouse pointer is input to the first page when the operation of changing the display content of the message or when the first page of the material A displayed on the terminal 10a for the presenter is synchronously displayed on the terminal 10b for the participant. This means an operation or the like for changing the display content of the participant terminal 10b.

  Note that, in the participant terminal 10b, the synchronization content may be displayed on the entire display screen, or the synchronization content may be displayed on a part of the display screen. Further, the entire display screen of the presenter terminal 10a may be synchronized, or a part of the display screen may be synchronized. For this reason, for example, even when the mouse pointer operated by the presenter on the presenter terminal 10a moves synchronously on the participant terminal 10b (synchronous state), the mouse pointer for the participant terminal 10b is separately provided. (For example, outside the synchronized display screen). In the synchronized display screen, both the mouse pointer in the synchronized state operated by the presenter and the mouse pointer for the participant terminal 10b operated by the participant may be displayed. The input operation of the mouse pointer in the presenter terminal 10a is included in the operation of changing the display content of the participant terminal 10b.

  FIG. 6 shows an example of the operation type table. In the operation type table shown in FIG. 6, five operation types of "material display", "pen", "pickup", "page switching", and "pointer" are set in accordance with the operation content. For example, the operation type determination unit 13 refers to the operation type table and specifies the operation type corresponding to the content of the operation performed by the presenter. Further, the operation type determination unit 13 specifies the operation type corresponding to the content of the operation by the participant with reference to the operation type table. If there is no operation type corresponding to the operation content, the operation type determination unit 13 determines that there is no operation type. Further, the operation content registered in the operation type table is not limited to the content of FIG. For example, the operation content and operation type registered in the operation type table may be different for the presenter and the participant. In this case, the presenter's operation type table and the participant's operation type table may be provided separately.

  The synchronization determining unit 14 determines whether the participant terminal 10b is to be synchronized with the presenter terminal 10a or is to be asynchronous based on the determination result of the operation type determining unit 13. Specifically, when the content of the operation performed by the presenter corresponds to a predetermined operation type (see FIG. 6), the synchronization determination unit 14 determines “synchronization”. When the operation content of the participant corresponds to the predetermined operation type (see FIG. 6), the synchronization determination unit 14 determines that the operation is “asynchronous”. When the content of the operation by the presenter or the content of the operation by the participant is “no operation type”, the synchronization determination unit 14 determines that the content is “asynchronous”.

  The display control unit 15 controls the display content of the display screen of the participant terminal 10b based on the determination result of the synchronization determination unit 14. Specifically, when the synchronization determination unit 14 determines that the synchronization is “synchronous”, the display control unit 15 reflects and displays the display content according to the content of the operation performed by the presenter on the participant terminal 10b. For example, when the presenter displays a new material A on the presenter terminal 10a, the synchronization determination unit 14 determines that the data is “synchronous”, and the display control unit 15 displays the material on the display unit 106 of the participant terminal 10b. A is displayed. Further, for example, when the presenter switches the display page of the material A from the first page to the second page on the presenter terminal 10a, the synchronization determination unit 14 determines that the display is “synchronous”, and the display control unit 15 The display page of the material A displayed on the display unit 106 of the user terminal 10b is switched from the first page to the second page. Similarly, when a character is written with the pen tool, a posted comment is picked up, or the presenter moves the mouse pointer, the display control unit 15 reflects these operation contents on the participant terminal 10b.

  On the other hand, when the synchronization determination unit 14 determines “asynchronous”, the display control unit 15 sets the participant terminal 10b to an asynchronous state (asynchronous mode) with respect to the presenter terminal 10a, and The operation content is reflected on the participant terminal 10b. For example, when the material A is displayed on the participant's terminal 10b in synchronization with the presenter's terminal 10a, and when the participant selects another material B, the synchronization determination unit 14 determines “asynchronous”. The display control unit 15 makes the participant terminal 10b asynchronous with the presenter terminal 10a, changes the display content of the participant terminal 10b, and displays the material B on the display unit 106. Further, for example, when the third page of the document A is displayed on the participant terminal 10b in synchronization with the presenter terminal 10a, the participant performs an operation of switching to the previous page (fourth page). In this case, the synchronization determination unit 14 determines “asynchronous”, and the display control unit 15 puts the participant terminal 10b into an asynchronous state with respect to the presenter terminal 10a, and is displayed on the display unit 106 of the participant terminal 10b. The displayed page of the material A is switched from the third page to the fourth page (change). Similarly, when a character is written with the pen tool, a posted comment is created, or a participant moves the mouse pointer, the display control unit 15 causes the participant terminal 10b to be asynchronous with the presenter terminal 10a. State, and these operation contents are reflected on the participant terminal 10b.

  As described above, the display control unit 15 functions as a synchronization canceling unit that cancels the synchronous state (switches to the asynchronous state) by the participant performing a preset operation on the participant terminal 10b. In the released state (asynchronous state), the presenter performs a preset operation on the presenter's terminal 10a, thereby functioning as a re-synchronization unit that returns to the synchronized state (cancels the asynchronous state) again.

  Next, the flow of processing in the electronic conference system 100 will be described. 7 and 8 are operation flowcharts of the electronic conference system 100. Here, as an example, the presenter P makes a presentation on the material A in the electronic conference using the terminal 10a for the presenter, and the participant S participates in the electronic conference using the terminal 10b for the participant, Description will be made assuming a case where the electronic conference proceeds while P and the participant S perform desired operations. Note that the electronic conference system 100 includes one presenter terminal and a plurality of participant terminals interconnected via the communication network 20. Here, one presenter terminal is used. The following description focuses on the terminal 10a and one participant terminal 10b.

  First, the presenter P selects a file of the material A stored in the storage unit 103 (FIG. 2) on the presenter terminal 10a. Thereby, the content of the material A is displayed on the display unit 106 of the presenter terminal 10a (S101). For example, the first page (first page) of the material A is displayed. In addition, the presenter terminal 10a transmits presenter operation information indicating the operation content of the presenter P (here, display of new material A) including information of the material A (for example, the ID and the page number of the material A). Notify the participant terminal 10b.

  Next, the presenter operation receiving unit 11 of the participant terminal 10b receives the presenter operation information from the presenter terminal 10a (S201). Here, the presenter operation receiving unit 11 receives the operation content including the ID of the material A (“display new material A”).

  Next, the operation type determination unit 13 of the participant terminal 10b determines the operation type based on the presenter operation information (S202). Here, the operation type determination unit 13 refers to the operation type table shown in FIG. 6 and specifies the operation type (“material display”) corresponding to the operation content (“display new material A”).

  Next, the synchronization determination unit 14 of the participant terminal 10b determines whether the participant terminal 10b is synchronous or asynchronous based on the determination result of the operation type determination unit 13 (S203). Here, since “material display” is specified as the operation type, the synchronization determination unit 14 determines “synchronization”.

  Next, the display control unit 15 of the participant terminal 10b controls the display content of the display screen on the participant terminal 10b based on the determination result of the synchronization determination unit 14 (S204). Here, since the synchronization determination unit 14 determines “synchronous”, the display control unit 15 reads out the material A stored in the media DB 31 and displays the first material A on the display unit 106 of the participant terminal 10b. Display the page.

  In the processes of S201 to S204, the presenter's terminal 10a and the participant's terminal 10b enter a synchronized state (synchronous mode), and the same contents are displayed.

  Subsequently, the participant S performs a desired operation on the participant terminal 10b. Here, it is assumed that the participant S switches the display page (first page) of the material A displayed on the display screen to the second page (S205).

  Then, the participant operation acquisition unit 12 of the participant terminal 10b acquires the participant operation information indicating the content operated by the participant S. Here, the participant terminal 10b acquires the participant operation information indicating the operation content of the participant S (here, the page switching of the material A) including the information of the material A (for example, the ID of the material A). (S206).

  Next, the operation type determination unit 13 of the participant terminal 10b determines the operation type based on the participant operation information (S207). Here, the operation type determination unit 13 specifies the operation type (“page switching”) corresponding to the operation content (“page switching of the material A”) with reference to the operation type table shown in FIG.

  Next, the synchronization determination unit 14 of the participant terminal 10b determines whether the participant terminal 10b is synchronous or asynchronous based on the determination result of the operation type determination unit 13 (S208). Here, since “page switching” is specified as the operation type, the synchronization determination unit 14 determines “asynchronous”.

  Next, the display control unit 15 of the participant terminal 10b controls the display screen of the participant terminal 10b based on the determination result of the synchronization determination unit 14 (S209). Here, since the synchronization determination unit 14 determines “asynchronous”, even if the first page of the material A is displayed on the display unit 106 of the presenter terminal 10a, the display control unit 15 The display content of the display unit 106 of the terminal 10b is changed to display the second page of the material A.

  In the processing of S205 to S209, the participant terminal 10b enters an asynchronous state (asynchronous mode), and different contents are displayed on the presenter terminal 10a and the participant terminal 10b.

  Subsequently, the presenter P performs a desired operation on the presenter terminal 10a. Here, it is assumed that the presenter P has written characters on the first page of the material A displayed on the display unit 106 using the pen tool (S102 in FIG. 8).

  Then, the terminal 10a for the presenter operates the presenter P (including the information indicating the position (coordinate) of the written character, the ID of the written material A and the page number) (here, the material A by the pen tool). To the participant terminal 10b.

  Next, the presenter operation receiving unit 11 of the participant terminal 10b receives the presenter operation information from the presenter terminal 10a (S210).

  Next, the operation type determination unit 13 of the participant terminal 10b determines the operation type based on the presenter operation information (S211). Here, the operation type determination unit 13 refers to the operation type table shown in FIG. 6 and specifies the operation type (“pen”) corresponding to the operation content (“writing to material A by pen tool”).

  Next, the synchronization determination unit 14 of the participant terminal 10b determines whether the participant terminal 10b is synchronous or asynchronous based on the determination result of the operation type determination unit 13 (S212). Here, since “pen” is specified as the operation type, the synchronization determination unit 14 determines “synchronization”.

  Next, the display control unit 15 of the participant terminal 10b controls the display content of the display screen on the participant terminal 10b based on the determination result of the synchronization determination unit 14 (S213). Here, since the synchronization is determined to be “synchronous” by the synchronization determination unit 14, the display control unit 15 changes the display content of the display unit 106 of the participant terminal 10b to change the first content of the material A in which the characters are written. Display the page.

  In the processing of S210 to S213, the participant terminal 10b is again in the synchronized state (synchronous mode), and the same contents are displayed on the presenter terminal 10a and the participant terminal 10b.

  As described above, in the electronic conference system 100, synchronous / asynchronous is automatically switched according to the desired operation of the presenter and the participant, and the display content of the participant terminal 10b is changed.

  Next, a method of recording a conference in the electronic conference system 100 will be described. FIG. 9 is a functional block diagram illustrating the configuration of the server 30 and the operation terminal 10. FIG. 9 illustrates the participant terminal 10b as an example. The participant terminal 10b further includes an operation information transmitting / receiving unit 41, a minutes information receiving unit 42, and a minutes playing unit 43 in the configuration shown in FIG. Although not shown, the presenter terminal 10a also includes an operation information transmitting / receiving unit 41, a minutes information receiving unit 42, and a minutes playing unit 43.

  The operation terminal 10 transmits operation information (presenter operation information and participant operation information) indicating the contents operated by the user (presenter and participant) during the meeting, to material information indicating the material displayed on the operation terminal 10. And the time information indicating the operated time and the terminal information for identifying the operated terminal, and transmitting the information to the server 30. For example, the operation information transmitting / receiving unit 41 of the participant terminal 10b associates the participant operation information acquired by the participant operation acquisition unit 12 with the material information (for example, page information), the time information, and the terminal information, and Send to The operation information transmitting / receiving unit 41 functions as material information receiving means for receiving material information indicating information of the material to be displayed, and as operation information receiving means for receiving operation information indicating the content operated by the user at each of the plurality of operation terminals 10. . Similarly, in the presenter terminal 10a, the operation information transmitting / receiving unit associates the presenter operation information acquired by the presenter operation acquisition unit with the material information (for example, page information), the time information, and the terminal information, and sends the information to the server 30. Send.

  The server 30 includes an operation information transmission / reception unit 32 and an operation information management unit 33. These elements are realized by the CPU 301 executing a program stored in the memory 302 (see FIG. 2). The storage unit 303 includes a file DB 35 for storing material data and an operation information DB 36 for storing operation information received from the presenter terminal 10a and the participant terminal 10b.

  The operation information transmitting / receiving unit 32 receives the operation information transmitted from the presenter terminal 10a and the participant terminal 10b. For example, the operation information transmitting / receiving unit 32 sequentially receives operation information transmitted from the operation terminal 10 during a conference in a time-series manner.

  The operation information management unit 33 (information recording unit) stores the operation information received by the operation information transmission / reception unit 32 in the operation information management table of the operation information DB 36. FIG. 10 is a diagram illustrating an example of the operation information management table. The example of FIG. 10 illustrates a case where the conference is started at “2015/03/18 10: 00: 00: 00”. For example, the management number “1” indicates that the presenter sets the page of the material on the presenter terminal “000001 (master)” at the time “2015/03/18 10:00:41” (40 seconds after the start of the conference). It shows operation information when the number is switched from the first page to the second page. For example, the management number “3” is written by the participant using the pen at the participant terminal “000005 (slave)” on the second page of the material at the time “2015/03/18 10:01:15”. Indicates the operation information when the operation is performed. In the data item of the operation information management table, information of a material to be operated, for example, information indicating a name of a material written with a pen, a location (coordinate) of the written material, and the like are registered. As described above, in the operation information management table, the operation information performed by the presenter and the participant during the conference is recorded in association with the information of the material that is synchronously displayed. The time information may be real time, or may be the elapsed time from the start of the conference, but more preferably includes the real time and the elapsed time from the start of the conference. . By including the real time and the elapsed time, it is possible to distinguish, for example, a user who has participated in the conference later and made a speech, and a user who has participated in the conference from the beginning, and has an effect of preventing tampering. You can also. Further, according to this configuration, at the time of playing back the minutes, it is possible to play back as if all the users had participated in the meeting from the beginning, including the user who joined later in the meeting, and to play back the meeting later. The minutes of only the users who have participated in the conference from the beginning, excluding the participating users, can be reproduced. The operation information management unit 33 associates a series of information (minutes information) recorded in the operation information management table with the materials used for the conference.

  The operation information transmitting / receiving unit 32 transmits information (minutes information) of the operation information management table registered by the operation information management unit 33 to the operation terminal 10. For example, the operation information transmitting and receiving unit 32 transmits the minutes information shown in FIG. 10 in which a series of operations (events) performed during the conference is registered after the conference ends, to the presenter terminal 10a and the participant terminal. 10b.

  The minutes information receiving unit 42 of the participant terminal 10b receives the minutes information transmitted from the server 30 and stores the minutes information in the minutes DB 37.

  The minutes playing unit 43 plays back the minutes of the past in accordance with a user operation (reproduction request). Specifically, the minutes reproducing unit 43 reads out the materials used in the target conference from the media DB 31 and causes the display unit 106 to display the materials. Next, the minutes reproducing unit 43 reflects the display contents according to the operation contents based on the time information of the minutes information. For example, when the minutes playback unit 43 receives a minutes playback instruction from the user, the minutes playback unit 43 displays the first page of the material A, and then displays the second page of the material A 40 seconds after the reception of the playback instruction. (Management number "1" in FIG. 10). Next, the minutes playback unit 43 plays back the audio data (management number "2" in FIG. 10). Next, the minutes reproducing unit 43 draws a character or a figure input by a pen at a predetermined position (coordinates) on the second page of the material A (management number "3" in FIG. 10). In this way, the past conference is reproduced.

  The operation information transmission / reception unit 32 of the server 30 transmits the minutes information to the user's operation terminal 10 sequentially based on the time information when receiving the minutes reproduction instruction from the user. 43 may be sequentially reproduced based on the received minutes information.

  In the conference system 100 according to the present embodiment, the information on the materials used in the conference and the information on the operation performed by the user are recorded (managed) not as integrated moving image information but as mutually different information. . Then, at the time of reproduction, information on operations performed in the conference is reflected in the materials used in the conference based on time information.

  According to the above configuration, since the operation information is recorded separately from the material, the data amount of the minutes can be reduced as compared with the case where the meeting is recorded as moving image information, and the efficient recording of the minutes of the meeting can be achieved. Records can be realized.

  Also, in the conference system 100, the user can perform a desired operation during the reproduction of the minutes. Specifically, as shown in the processing of S205 to S209 in FIG. 7, in the asynchronous mode, it is possible to reflect the operation content different from the content performed in the conference. For example, when the user switches from the second page to the third page while the content indicated by the management number “3” in FIG. 10 is being played, the display control unit 15 displays the third page. Thereafter, when the time of “pickup” indicated by the management number “4” is reached, the minutes reproducing unit 43 returns the material to the second page and displays the picked up comment in a predetermined place. As described above, the user can perform a desired operation at the time of playing back the minutes as well as the operation during the meeting, so that the degree of freedom of the user operation at the time of playing back can be increased.

  Here, operation information performed during playback of the minutes may be included in the minutes information (FIG. 10). Specifically, for example, when writing with the “pen” is performed on the operation terminal “local” performed during minutes playback, the operation information transmitting / receiving unit 41 of the operation terminal “local” transmits the operation information to the server 30. Send to When the operation information transmitting / receiving unit 32 of the server 30 receives the operation information from the operation terminal “local”, the operation information management unit 33 of the server 30 records the operation information in the operation information management table of the operation information DB 36. FIG. 11 shows the updated operation information management table. In FIG. 11, new operation information (management number “2”) is added.

  According to the above configuration, when the minutes are reproduced after the operation information management table of FIG. 11 is generated, the minutes reflecting the added operation information are reproduced. That is, the contents of the past conference can be dynamically managed.

  The electronic conference system 100 is not limited to the above configuration, and various configurations can be adopted. Hereinafter, the electronic conference system 100 according to the modified example will be described focusing on differences from the above configuration. In the electronic conference system 100 according to the following modified example, description of elements having the same functions as those of the electronic conference system 100 will be omitted.

  In the electronic conference system 100 according to the first modification, when the participant operation obtaining unit 12 obtains the operation content (participant operation information) by the participant, the display is performed without determining the operation type corresponding to the operation content. The control unit 15 may cause the participant terminal 10b to be in an asynchronous state (asynchronous mode) with respect to the presenter terminal 10a, and to cause the participant terminal 10b to display a display content according to the operation content. When the presenter operation receiving unit 11 receives the content of the operation by the presenter (presenter operation information), the operation type corresponding to the operation content is determined, and the display control unit 15 controls the participant terminal 10b. Along with the presenter terminal 10a being in a synchronized state (synchronous mode), display contents corresponding to the operation content corresponding to the operation type may be displayed on the participant terminal 10b.

  According to the electronic conference system 100 according to Modification 1, the presenter performs an important operation (operation corresponding to the operation type), for example, an operation of changing the display content displayed on the presenter terminal 10a. When the above operation is not performed, the display content corresponding to the desired operation of the participant terminal is displayed on the participant terminal 10b. 10b is displayed.

  In the electronic conference system 100 according to the second modification, when the presenter operation receiving unit 11 receives the operation content (presenter operation information) by the presenter, the display control is performed without determining the operation type corresponding to the operation content. The unit 15 may cause the participant terminal 10b to be in a synchronized state (synchronous mode) with the presenter terminal 10a, and may cause the participant terminal 10b to display a display content according to the operation content. Then, when the participant operation acquisition unit 12 acquires the operation content (participant operation information) by the participant, the operation type corresponding to the operation content is determined, and the display control unit 15 controls the participant terminal 10b. In addition to the asynchronous state (asynchronous mode) with respect to the presenter terminal 10a, the display content corresponding to the operation content corresponding to the operation type may be displayed on the participant terminal 10b.

  According to the electronic conference system 100 according to the second modification, a more important operation (operation corresponding to the operation type) by the participant, for example, the display content displayed on the participant terminal 10b in synchronization with the presenter terminal 10a Is changed only when the operation of changing the is performed, the display content corresponding to the operation is displayed on the participant's terminal 10b, and while the above operation is not performed, according to the desired operation of the presenter, The displayed content is displayed on the participant terminal 10b. Note that the electronic conference system 100 according to Modification 2 may be configured to automatically shift to the synchronized state when the display content according to the operation content of the participant is displayed on the participant terminal 10b.

  In the electronic conference system 100 according to the third modification, the display content according to the operation content of the participant is displayed on the participant terminal 10b while maintaining the synchronized state of the presenter terminal 10a and the participant terminal 10b. Is also good. For example, when the presenter's terminal 10a and the participant's terminal 10b are in a synchronized state and the first page of the material A is displayed on the respective display screens, when the participant switches to the second page, display control is performed. The unit 15 divides the display screen into a first screen for the synchronous mode and a second screen for the asynchronous mode, displays the first page on the first screen corresponding to the synchronous mode, and displays the first page on the second screen. The second page is displayed according to the asynchronous mode. In this case, the size of the first screen may be smaller than that of the second screen. Further, the first screen and the second screen may be displayed side by side, or the other screen may be displayed superimposed on one screen. Further, in the above example, when the participant performs an operation of selecting (clicking) the first screen, the display control unit 15 cancels the asynchronous mode on the second screen and changes the first screen to the full screen display. You may switch.

  According to the electronic conference system 100 according to Modification 3, the participant displays the content corresponding to the desired operation on the participant terminal 10b while checking the same content as the display content of the presenter terminal 10a. be able to.

  In the electronic conference system 100 according to Modification 4, when the participant terminal 10b is in the asynchronous state, the asynchronous state may be maintained based on the instruction of the participant. For example, when the participant selects the asynchronous button on the display screen with the mouse pointer, the participant terminal 10b maintains the asynchronous state. Further, for example, while the participant is touching the display screen with a finger, the participant terminal 10b may be configured to maintain the asynchronous state.

  Further, in the electronic conference system 100 according to the fourth modification, when the presenter's operation content corresponds to an operation type related to an important operation among a plurality of operation types while maintaining the asynchronous state, the forced It is also possible to cancel the asynchronous state and shift to the synchronous state. Important operations include, for example, displaying a new material, writing to the material, and the like.

  FIG. 12 is a functional block diagram showing a specific configuration of the participant terminal 10b in the electronic conference system 100 according to the fifth modification. In the electronic conference system 100 according to Modification 5, the participant terminal 10b further includes a priority of the operation type corresponding to the presenter operation information (priority for presenter) and an operation type corresponding to the participant operation information. Priority (participant priority) is obtained and compared by the priority comparison unit 16. The priority indicates the importance of the operation content of the presenter or the participant. For example, as shown in FIG. 13, “material display” has the highest priority, and thereafter, “pen”, “pickup”, “page” The priority decreases in the order of “switch” and “pointer”. The priority is set in advance in the operation type table shown in FIG. Note that the presenter priority and the participant priority may be the same as shown in FIG. 13 or may be different as shown in FIG.

  When the period in which the presenter operation receiving unit 11 receives the presenter operation information and the period in which the participant operation obtaining unit 12 obtains the participant operation information overlap, the priority comparing unit 16 compares the respective priorities. Compare.

  FIG. 15 is an operation flowchart of the electronic conference system 100 according to the fifth modification. First, in the participant terminal 10b, the presenter operation receiving unit 11 receives presenter operation information from the presenter terminal 10a (S11), and the participant operation obtaining unit 12 obtains participant operation information (S12). . Next, the operation type determination unit 13 specifies each operation type corresponding to the presenter operation information and the participant operation information (S13). Next, the priority comparison unit 16 acquires the respective priorities (priority for the presenter and priority for the participant) corresponding to the respective operation types (S14), and the priority for the presenter is obtained for the participant. It is determined whether the priority is higher than the priority (S15). If the presenter priority is higher than the participant priority (YES in S15), the display control unit 15 displays the display content according to the presenter's operation on the display screen of the participant terminal 10b. (S16). On the other hand, if the participant priority is higher than the presenter priority (NO in S15), the display control unit 15 displays the display content according to the participant's operation content on the display screen of the participant terminal 10b. (S17). After the processing of S16 and S17, the above processing is repeated until the electronic conference ends (S18).

  As described above, in the electronic conference system 100 according to Modification Example 5, the display control unit 15 displays the display content according to the operation information corresponding to the operation type having the higher priority among the presenter operation information and the participant operation information. Is displayed on the display screen of the participant terminal 10b. For example, when the presenter moves the mouse pointer on the material screen (see FIG. 5) displayed on the presenter terminal 10a, the participant displays the material screen (FIG. 5) displayed on the participant terminal 10b. When the page is switched, the participant's priority (“2”) is higher than the presenter's priority (“1”). "Page switching" is reflected on the participant terminal 10b without reflecting on the participant terminal 10b.

  The electronic conference system 100 according to Modification 5 is not limited to the above configuration. For example, the priority comparison unit 16 may compare the presenter priority with a preset predetermined priority. When the presenter priority is equal to or lower than the predetermined priority, the display control unit 15 does not reflect the display content corresponding to the presenter operation information corresponding to the presenter priority on the participant terminal 10b. It may be configured.

  In the electronic conference system 100 according to the fifth modification, while the display content corresponding to the operation information having the higher priority is displayed on the participant terminal 10b, the display content corresponding to the other operation information is not received. Alternatively, after the display content corresponding to the operation information having the higher priority is displayed on the participant terminal 10b, the display content corresponding to the other operation information may be accepted. For example, while writing to the material by the pen tool is being performed in the participant terminal 10b (asynchronous state), the content of the operation by the presenter (for example, display of a new material) is not accepted, and the presenter writes to the material. May be displayed on the participant's terminal 10b at the end of the process.

  The information on the priority can be used at the time of playing back the minutes. FIG. 16 is a functional block diagram showing the configuration of the server 30 and the operation terminal 10. The participant terminal 10b further includes an operation information transmitting / receiving unit 41, a minutes information receiving unit 42, and a minutes playing unit 43 in the configuration shown in FIG. For example, during playback of past minutes in accordance with a user operation (playback request), when writing to a material by a “pen” is about to be played back, or during playback (management number “3” in FIG. 10), the user Has performed the page switching operation, the priority of “pen” is higher than “page switching”, so the minutes playback unit 43 does not reflect the operation of “page switching”, but displays the material by “pen”. Play writing. Further, when the minutes of the comment are being reproduced, when the pickup of the comment by “pickup” is about to be reproduced or during the reproduction (control number “4” in FIG. 10), when the user performs the display operation of the new material, Since the priority of “material display” is higher than that of “pickup”, the minutes reproducing unit 43 executes an operation different from the contents of the minutes by reflecting the operation of “material display”.

  Note that the priority information may not be used during the meeting but may be used only when the minutes are reproduced. In this case, the minutes playback unit 43 plays back the operation information having the higher priority among the plurality of pieces of operation information having the same operation time among the operation information received by the operation information transmission / reception unit 32 of the server 30. In this case, the priority comparison unit 16 determines the priority of the operation information based on, for example, a priority determination table illustrated in FIG. In the priority determination table shown in the figure, the priority is set in accordance with the type of the operated terminal (presenter terminal “master”, participant terminal “slave”, “own terminal”) and the operation type. You. As shown in FIG. 18, the operation type of the current terminal used by the user who instructed the reproduction request may be included in the priority determination table.

  In the electronic conference system 100 according to Modification 6, the participant operation acquisition unit 12 acquires the participant operation information from the participant terminal 10b, which is its own terminal, and receives the participant information from the other participant terminals 10c and 10d. Operation information may be acquired. That is, the participant operation acquisition unit 12 may be configured to acquire operation information from terminals other than the own terminal. In the above configuration, for example, when the operation content in the participant operation information received from the participant terminal 10c corresponds to a predetermined operation type, the operation content may be reflected on the participant terminal 10b. . According to the above configuration, for example, when a comment is posted on the participant terminal 10c, the posted comment is displayed on the participant terminal 10b.

  By the way, in the electronic conference system 100 according to each of the above-described embodiments, the synchronization determination unit 14 may be omitted. An electronic conference system 100 that does not include the synchronization determination unit 14 will be described below as a seventh modification.

  In the electronic conference system 100 according to Modification 7, the display control unit 15 may control the display content of the display screen of the participant terminal 10b based on the determination result of the operation type determination unit 13. Specifically, when the content of the operation performed by the presenter corresponds to a predetermined operation type (see FIG. 6), the display control unit 15 reflects the display content corresponding to the operation content on the participant terminal 10b. It may be displayed.

  For example, the content of the presenter's operation (for example, display of a mouse pointer or writing with a pen tool) is reflected on the participant's terminal 10b, and the content of the participant's operation is displayed with the mouse pointer or the pen tool (within the same page). In the case of writing, the operation content of the participant may be reflected on the participant terminal 10b. That is, both the content of the presenter's operation and the content of the participant's operation may be reflected on the participant terminal 10b. Therefore, it is possible to set an intermediate state (semi-synchronous state) between the synchronous state and the asynchronous state, which reflects the content of the presenter's operation and the content of the participant's operation at the same time. As described above, the display control unit 15 can realize the semi-synchronous mode regardless of the synchronous mode / asynchronous mode. That is, the display control unit 15 can also change the display content displayed on the participant terminal 10b to display content according to both the presenter's operation content and the participant's operation content.

  When the electronic conference system 100 includes the synchronization determination unit 14, for example, the system shown in Modification 8 below can be configured using the determination result of the synchronization determination unit 14.

  FIG. 19 is a functional block diagram illustrating a specific configuration of the electronic conference system 100 according to the eighth modification. In the electronic conference system 100 according to Modification 8, the participant terminal 10b further includes a synchronization information notification unit 17, and the presenter terminal 10a further includes a synchronization information acquisition unit 21 and a display control unit 22. I have.

  The synchronization information notifying unit 17 of the participant terminal 10b transmits synchronization information indicating whether or not the participant terminal 10b is synchronized with the presenter terminal 10a, and the display contents of the display screen when not synchronized. The synchronization information including the information is transmitted to the presenter terminal 10a.

  The synchronization information obtaining unit 21 of the presenter terminal 10a obtains the synchronization information from the participant terminal 10b. Note that the synchronization information acquisition unit 21 acquires the synchronization information from all the participant terminals included in the electronic conference system 100.

  The display control unit 22 of the presenter terminal 10a controls the display content of the display screen of the presenter terminal 10a based on the synchronization information acquired by the synchronization information acquisition unit 21. For example, the display control unit 22 calculates the total number (synchronization number) of the participant terminals in the synchronized state among all the participant terminals, and displays the number of synchronizations on the display screen of the presenter terminal 10a. The display control unit 22 calculates the ratio (synchronization rate) of the number of participant terminals in a synchronized state to the number of all participant terminals, and displays the synchronization rate on the display screen of the presenter terminal 10a. It may be displayed. In addition, the display control unit 22 may display (for example, thumbnail display) the display contents displayed on the display screen of the participant terminal 10b in the asynchronous state side by side on the display screen of the presenter terminal 10a. .

  In the electronic conference system 100 according to Modification 9, in the electronic conference system 100 according to Modification 8, the participant terminal 10b does not include the participant operation acquisition unit 12 and the operation type determination unit 13. FIG. 20 is a functional block diagram showing a specific configuration of the electronic conference system 100 according to the ninth modification. The presenter terminal 10a has the same configuration as that shown in FIG. As the participant terminal 10b, a known operation terminal that performs synchronous display can be applied. According to the above configuration, as in the case of Modification 8, the display rate of the presenter terminal 10a displays the synchronization rate and the display content of the asynchronous participant terminal 10b. Therefore, the presenter can grasp the degree of interest of the participant in the content of his presentation.

  Note that a program for implementing the electronic conference system 100 according to the ninth modification includes a presenter terminal on at least a part of the display screen of the participant terminal 10b (first operation terminal) in a plurality of operation terminals. A participant terminal 10b in a synchronized state with respect to the number of all participant terminals 10b, which is a program capable of displaying at least a part of the display contents of the 10a (second operation terminal) in a synchronized state. Can be a program for causing a computer to function as display control means for displaying the ratio (synchronization rate) of the number on the display screen of the presenter terminal 10a. Further, the display control means may display the display content of the participant terminal 10b in an asynchronous state on the display screen of the presenter terminal 10a.

  FIG. 21 is a functional block diagram illustrating a specific configuration of the electronic conference system 100 according to the tenth modification. In the electronic conference system 100 according to the tenth modification, the participant terminal 10b further includes a participation mode receiving unit 44 in the configuration shown in FIG.

  The participation mode receiving unit 44 receives a participation mode selected by a participant participating in the conference. Specifically, when a participant joins in the middle of a conference, the first participant mode in which a participant joins a conference that progresses in real time from the time of participation, and the proceedings from the start of the conference until the real-time conference progresses The user selects one of the second participation modes for participating in a real-time conference after playing the recording at high speed. When the participant selects the first participation mode, a synchronous display or the like is performed in real time from the time of participation. When the participant selects the second participation mode, the minutes reproducing unit 43 reproduces the minutes from the start of the conference to catch up with the progress of the real-time conference at a high speed. When catching up with the progress of the real-time conference, synchronous display and the like are performed in real time.

  The elements described in the embodiment and the modifications of the electronic conference system 100 described above are used in an information processing apparatus network-connected to the operation terminal 10 (presenter terminal 10a, participant terminals 10b, 10c, and 10d). The program may be realized by executing a program by a CPU. The information processing device may be, for example, the server 30 illustrated in FIG. In this case, in the information processing apparatus, the participant operation acquisition unit 12 acquires the participant operation information from each participant terminal, and the operation type determination unit 13 specifies the operation type corresponding to each participant terminal, The synchronization determination unit 14 determines synchronization and non-synchronization corresponding to each participant terminal. The display control unit 15 controls the display content of the display screen of each participant terminal based on the determination result of the synchronization determination unit 14.

  In addition, the above-described embodiment and each modified example are examples, and each form can be combined.

  Further, the network configuration of the electronic conference system 100 is not limited to the configuration shown in FIG. For example, as shown in FIG. 22, a configuration (star type) in which the operation terminals 10 are mutually connected via the participant terminal 10b may be used. Further, as shown in FIG. 23, a configuration (P2P (Peer to Peer) type) in which participant terminals 10b, 10c, and 10d are connected with the presenter terminal 10a as a starting point may be used.

  Further, in the network configuration shown in FIG. 4, the connection from each operation terminal 10 to the server 30 may be established by the user launching a web browser and specifying a common URL (server). An application started on the operation terminal 10 may automatically connect to the server 30 according to a preset address. The connection between each operation terminal 10 and the server 30 may be connected by a Web Socket, or each operation terminal 10 may connect to the server 30 at regular intervals (polling) to simulate the operation terminal. Information may be exchanged between the ten.

  Note that the mutual transition (switching) between the synchronous state and the asynchronous state in the electronic conference system 100 is performed when the initial setting (default) of the operation terminal 10 is the asynchronous state and the asynchronous state is released and the state is shifted to the synchronous state. If the initial state is a synchronous state, the synchronous state is released and the state is shifted to an asynchronous state.

  In the above description, an electronic conference system has been described as an example of the information processing system.
