In this process, the process of setting the terminal M1-3 to the synchronous mode by the synchronizer P3 can be divided into two processes: a mode setting process A1 and a synchronous process A100 to page transition performed by the asynchronous person P2. .

  First, an outline of the mode setting process A1 will be described. The synchronizer P3 makes a synchronization mode switching request A5 to the terminal M1-3 in order to display the page displayed by the synchronized person P2 on the terminal M1 on hand. The terminal M1 that has been switched to the synchronous mode transmits a mode switching notification A10 to the display management apparatus M10. The display management apparatus M10 that has received the mode switching notification A10 obtains A15 information serving as a reference for selecting a synchronization target from the information source management apparatus M20. The display device M10 selects a synchronization target based on the acquired information, determines a page to be displayed, and notifies the terminal M1-3.

  Next, an overview of the synchronization process A100 will be described. In order to switch the page displayed by the synchronized person, a page transition request A105 is made to the display terminal M1-2. The terminal M1-2 that has received the page transition request A105 transmits a page transition notification A110 to the display management apparatus M10. The M10 display management device M10 that has received the page transition notification A110 sends a page transition request A115 so that the terminal M1-3 handled by the synchronizer P3 is synchronized with the terminal M1-2.

Note that the user IDT 2052 specifies NULL for terminals that are not used.

  FIG. 10 shows a material browsing history table T3000. In the document browsing history table T3000, a record is held using a user ID T3001 that is an ID for uniquely identifying a conference participant as a key. For each record, the display page IDT3003 indicating the page in the displayed document IDT3003, the display start date and time T3004, the display time T3005 indicating the page display period, and the display start date and time required to specify the displayed page The operation mode T3006 of the terminal M1 is held.

  FIG. 11 shows a conference participant table T10000. In the conference participant table T10000, a record is held using a user ID T10001 that is an ID for uniquely identifying a conference participant as a key. For each record, the user name T10002 that shows the name of the participant, the company name T10003 that shows the company to which the participant belongs, the department T10004 that shows the department to which the participant belongs, and the status of the participant in the company Holds a position T10005 indicating.

  Before starting the conference, it is registered in the display management apparatus M10. The display content registrant P4 uploads materials from the display content registration terminal M40 using the material management function F1002 of the display management device M10. The uploaded material is stored in the material table T1000.

  Thereafter, a conference participant comes to the conference room and turns on the power of the terminal M1. When the power is turned on, the terminal M1 issues a download request for data to the display management device M10. The display management apparatus M10 that has received the download request for the material distributes the material according to the flow shown in FIG. First, when a download request is received, a terminal ID, a material ID of a displayed material, a displayed page number, and a material update date and time are acquired from the terminal M1 (S10003). To check the necessity of distribution of the document to the terminal M1 that requested the download, the terminal status table T2000 is searched using the acquired terminal ID as a key, the document IDT2002 is acquired, and the update date T1005 of the document is stored in the document table. Obtained from T1000. If the terminal ID is different or the material has been updated, it is determined that the material needs to be distributed, and the material is distributed to the terminal M1.

  Thus, the same material is stored in all terminals M1 of the conference participants. When the conference begins, the presenter announces, and participants of the conference listen to the presenter while viewing the page that the presenter is explaining. At this time, the presenter may be more concerned about where other participants are watching. For example, during a question-and-answer session after the presentation is over, a person who does not know his or her boss raises his hand and a person who does not know at all asks a question.

  At this time, the conference participant changes the operation mode of his / her terminal M1 to the synchronous mode in order to display the document on his / her terminal M1 in synchronization with the page being browsed by other participants. When the operation mode is switched, the terminal M1 notifies the display management apparatus M10 that the operation mode has been switched. Upon receiving the operation mode switching notification, the display management apparatus M10 receives the operation mode change in the flow shown in FIG. First, it is determined what the operation mode of the terminal M1 is (S10103), and it is registered in the terminal state table T2000. That is, if the mode is the synchronization mode, the synchronization target T2006 is selected from the conference participants (S10150). Since synchronization is not performed in the browsing mode, the secret mode, and the announcement mode, the synchronization target T2006 is registered as none (S10110). If the mode is shared, the presenter is registered in the synchronization target T2006 (S10105). Also, each operation mode T2005 is registered.

  An example in which the attributes of the participants are used as the synchronization target selection process S10150 will be described in detail with reference to FIG. First, the participant who requested the synchronization: the synchronizer P3 is searched from the terminal unique information table T2050 using the terminal ID as a search condition, and the user ID is acquired. Using the user ID of the synchronizer P3 as a search condition, company name T10002, department T10003, and title T10005 are acquired from the conference participant table T10000. Of these attributes, the company name T10002 and the department T10003 as search conditions are used as search conditions, and the conference participant table T10000 is referenced again to acquire candidates for synchronization (S10156). That is, a record in which the company name T10002 and the belonging department T10003 match is searched. Here, it is determined whether or not there is a synchronization target (S10159). When there are a plurality of conference participants, the person whose position T10005 is higher than the synchronous person and who has the lowest position is selected (S10162). It is preferable to add a rank corresponding to the position. As a result, it is possible to view the materials in synchronization with their immediate superiors, assume the contents of the instructions in advance, and be able to decide even more specific when receiving the instructions. If there is no corresponding conference participant, a person whose behavior characteristics are similar is selected (S10165). For example, referring to the material browsing history table T3000, the person with the longest period of displaying the same page in the browsing mode in the past conference is selected. As a result, it is possible to view the materials in synchronization with people who have similar thinking processes and interests.

  As a method for selecting the synchronization target, if the person with the highest job title T10005 is selected, the document can be viewed in synchronization with the chief officer of his / her related department. In addition, if you select the person who has the highest job title in the position T10005 lower than the sync P3, you can view the material in sync with your direct reports, and before the subordinates ask questions during the meeting questions. It is possible to assume the contents of the subordinate's questions and to think in advance how to follow.

  Also, in-house meetings may be commissioned to group companies. In such a case, use the relationship between companies or departments to select the person who has a higher position in the company that is the contractor or the department that is the contractor, so that the document can be synchronized with the person in charge of the contractor. You can see what you are requesting from the contractor.

  In addition, the speech history during the conference may be used as the behavioral characteristics of the conference participants. As an example of the utterance history, there is a utterance date and time acquired using the voice acquisition device added to the terminal M1. By synchronizing with people who have a lot of utterance history, you can view materials in sync with the central person in the conference.

  Next, processing when the synchronized person P2 performs a page operation will be described with reference to FIGS. FIG. 15 shows the processing of the terminal M1. When the page transition request is received from the synchronized person P2, it is confirmed whether or not the designated page exists in the terminal (S1003). If the page exists, the designated page is displayed on the display device H105 of the terminal M1 (S1005), and the display management device M10 is notified that the page has been switched and the page being displayed (S1007).

  When the display management apparatus M10 receives the terminal ID together with the page transition notification from the terminal M1, the display management apparatus M10 moves the data of the corresponding terminal M1 in the terminal state table T2000 to the material browsing history table T3000. At this time, the user ID T2052 acquired by referring to the terminal unique information table T2050 is registered in the user ID T3001, and the difference between the current time and the display start date T2004 is registered as the display time T3005 (S10003). The operation mode is determined (S10005), and the operation mode of the terminal M1 is acquired from the terminal state table T2000 using the acquired terminal ID as a search condition. In the announcement mode or the browsing mode, the terminal state table T2000 is searched according to the search condition with the terminal ID of the terminal M1 that has received the page transition notification as a synchronization target, and a terminal that requires page switching is acquired. For a terminal that requires page switching, a page transition request is issued together with the page number to be displayed.

  In the present embodiment, the configuration includes a plurality of terminals M1 and the display management device M10. However, even if each terminal has the function held by M10 and this function is realized by ad hoc communication between the terminals. Good.

  In Example 1, an internal meeting where the number of people is expected not to increase so much was taken up. In the second embodiment, it is assumed that the number of people is unspecified, such as a lecture at an academic conference. At this time, if the number of participants in the conference increases, it takes time to search for the synchronization target, and it takes time until the page is synchronized, so that the convenience is lost. Therefore, the selection range of the synchronization target is narrowed down. Since conferences are often attended by being seated and it is difficult to recognize the actions of distant people, in this modification, the selection range to be synchronized is filtered based on the location of the conference participants. Hereinafter, only parts that are different from the first embodiment will be described in order to avoid redundant description.

  FIG. 17 is a hardware configuration diagram of the terminal M1. The position of the terminal M1 is regarded as the location of the conference participant, and a position detection device H106 that detects the position of the terminal is added. As the position detection device H106, GPS may be used or an active tag may be used.

  FIG. 18 is a software configuration diagram of the terminal M1. A position notification F105 that detects the position of the terminal M1 and notifies the display management apparatus M10 of the position is added. The position notification F105 may be executed by polling at a certain interval, or may be notified when there is a position acquisition request from the display management apparatus.

  FIG. 19 shows a terminal state table T2000. In order to manage the location of the terminal M1, fields of north latitude T2007 and east longitude T2008 are added.

  FIG. 20 shows a process when the operation mode of the terminal M1 is switched. Before selecting the synchronization target, narrowing down the selection range of the synchronization target S10130 is added.

  FIG. 21 shows details of the process of narrowing down the selection range to be synchronized. In order to narrow down the synchronization targets, the distance between the terminals M1 is calculated from the north latitude T2007 and the east longitude T2008, and conference participants whose distance is equal to or smaller than a certain value are selected as synchronization target candidates (S10136). In conference lectures, the distance is a few tens of meters. Not only the distance but also a direction within a predetermined range may be used as the selection index. It should be noted that only a certain number in order of increasing distance may be selected as synchronization target candidates. Thereby, in a meeting, only the person in the near seat can be selected as a candidate for synchronization.

  In such a lecture meeting, coauthorship relationships and keywords of submitted papers may be used as attribute information of conference participants. If you select a conference participant who has a co-authorship relationship or a conference participant with a similar keyword in the submitted paper as the synchronization target, you can view the material synchronously with the person with similar interest, and the subsequent discussion is active Can be done.

  This is applicable when paying attention to a person who is different from the presenter of the meeting, such as a question-and-answer session in an internal or external meeting.
