  Here, the presentation material will be described in more detail with reference to FIG. FIG. 4 is a diagram illustrating an example of pages included in the presentation material. As the presentation material, a file created by presentation software (for example, PowerPoint (trademark)) is used.

  Such presentation material is composed of a plurality of pages. Each page included in the presentation material is composed of a text (also referred to as text information) BT and a comment (also referred to as comment information) CT, as shown in FIG.

  The body text BT is displayed as a page image on the display device 30 or the like in the presentation.

  Further, there is a body BT having a text (character string) TX for specifying a related material file related to the body BT.

  For example, as shown in FIG. 4, the body text BT has “<statistical data 2010.doc>” (text TX1) and “<report material 2010.doc>” (text TX2). The text (character string) TX is electronically recorded in the presentation material.

  The comment CT is composed of one or more comment sentences CS (for example, CS1, CS2, CS3 (see FIG. 4)). As the comment sentence CS, for example, a memorandum of the presenter on the corresponding page and a supplementary explanation sentence that supplementally explains the text BT related to the corresponding page are described. This comment CT is also electronically recorded in the presentation material.

  Some of the comment sentences CS include a character string indicating a visually-permitted user (specifically, “user name (arbitrary):”). This “viewing-permitted user” is a user who can visually recognize the comment sentence CS, in other words, a user who is permitted to visually recognize the comment sentence CS.

  For example, as shown in FIG. 4, a character string “presenter:” is inserted in the comment sentence CS2 at the beginning of the comment sentence CS2 as a visually-permitted user, and “listener:” is shown in the comment sentence CS3. A character string is inserted at the beginning of the comment sentence CS as a visually-permitted user. In such a case, the user who can visually recognize the comment sentence CS2 is limited to “presenter”, and the user who can visually recognize the comment sentence CS3 is limited to “listener”. Note that the visually-permitted user is not inserted in the comment sentence CS1. As described above, the comment sentence CS for which no visually-permitted user is set is treated as a comment sentence CS that can be visually recognized by all users. Therefore, the users who can visually recognize the comment sentence CS1 are “all”.

  Next, the related material file will be described in more detail. The related material file is a file related to the presentation material.

  As the related material file, various types of files such as a Word (trademark) file and an Excel (trademark) file are used.

Further, the presenter, on a desired page in the presentation material data, a character string (for example, the file name is represented by a symbol “<” and a symbol “>”) in which the file name of the “related material file” is expressed in a predetermined format ( (Also referred to as an identifier)). For example, a text string “<statistical data 2010.xls>” and a text string “<report material 2010.doc>” are recorded in the body text BT related to the page shown in FIG. In this manner, the presenter can associate the related material files (“statistical data 2010.xls” and “report material 2010.doc”) with a predetermined page in the presentation material data. As will be described later, the data management device 10 converts a character string according to a predetermined format (here, a character string surrounded by symbols “<” and symbols “>” included in the text BT) into related information. Is identified as a character string, and a file having a file name corresponding to the character string is identified as a related material file.

<1-2. Operation>
<1-2-1. Overview>
5 and 8 to 10 are flowcharts showing the operation of the data management apparatus 10. 6 and 7 are diagrams showing the display screens SA1 and SA2 on the presenter terminal 50, respectively. FIG. 11 is a diagram showing a request data DB transmitted from the listener terminal 70 to the data management apparatus 10. 12 to 16 are diagrams showing the display screens SB0 and SB1 in the listener terminal 70.

  Hereinafter, the operation of the system 100 in this embodiment will be described with reference to these drawings.

  Here, it is assumed that the material registration operation, the attendee data registration operation, and the like in the data management apparatus 10 are first performed by the organizer side user (for example, the presenter PA itself or the organizer side assistant user).

  The material registration operation includes an operation in which the presentation material and the related material file are stored in the storage unit 6 by an operation by the user on the organizer side. For example, the presenter operates the data management device 10 to store the presentation material file in the presentation material storage unit 6d and store the related material file in the related material file storage unit 6a in the data management device.

  The material registration operation also includes an analysis operation by the material analysis unit 25. This analysis operation includes a process of identifying and extracting a related material file related to the presentation material, and extracting the related material file extracted from one of a plurality of pages in the presentation material (in detail, Association processing associated with the body BT) of the page. The analysis operation also includes an operation of extracting a comment related to the presentation material. The material analysis unit 25 stores the text BT related to each page of the presentation material in the text storage unit 6b, and stores the comment CT in the comment storage unit 6c when the comment CT exists.

  FIG. 5 is a flowchart showing a material registration operation (analysis operation) in the data management apparatus 10. Hereinafter, the analysis operation (association processing or the like) will be described in detail with reference to FIG. This analysis operation is executed by the material analysis unit 25.

  First, in step S11, the material analysis unit 25 determines a processing target page that is a target of the material registration operation among a plurality of pages included in the presentation material. As the processing target page, the material analysis unit 25 first determines the first page among the plurality of pages included in the presentation material as the first processing target page.

  Next, the material analysis unit 25 stores the text BT related to the processing target page in the text storage unit 6b, and determines whether or not a comment CT exists in the processing target page (for example, the first page) (step) S12). Here, if it is determined that the comment CT exists, the material analysis unit 25 stores the comment CT in the comment storage unit 6c (step S13), and uses the comment CT as text related information related to the text BT. Associate with BT (step S14).

  Next, the material analysis unit 25 determines whether the text TX (see FIG. 4) for specifying the related material file related to the text BT exists in the text BT (step S15). If it is determined that the text TX exists, the material analysis unit 25 specifies the related material file corresponding to the text TX as the page related file related to the processing target page of the presentation material. Specifically, the material analysis unit 25 specifies related information for a character string (in this case, a character string surrounded by symbols “<” and symbols “>” included in the text BT) according to a predetermined format. The file having the file name corresponding to the character string among the files stored in the related material file storage unit 6a is specified as the page related file related to the processing target page. Then, the material analysis unit 25 associates the page related file with the text BT as related information related to the text BT (step S16).

  In step S17, it is determined whether or not there is an unprocessed page in the presentation material.

  If there is an unprocessed page, the process returns to step S11 again. In step S11, the material analysis unit 25 identifies the next page (second page) as a processing target page, and executes the same analysis processing and the like.

  On the other hand, if the same operation is repeated and it is determined that the analysis processing for all the pages of the presentation material is completed, this routine ends.

  Next, the operation for registering the audience data will be described.

  Also, the registration operation of the audience data includes the registration operation of the user ID and password of each audience. For example, the organizer's user may register the user information (user ID and password) of each listener by operating the data management device 10. In addition, the user information (user registration information) of each listener may be distributed individually to each listener in advance, for example, by mail. Each listener can perform a user authentication operation using the distributed user information.

  After these registration operations are finished, the presentation by the presenter PA is started. In the data management apparatus 10, in response to a request from the presenter terminal 50, the listener terminal 70, etc., processing corresponding to the request is executed.

<1-2-3. Presenter terminal display update operation>
When a predetermined start command is transmitted from the presenter terminal 50 to the data management apparatus 10, the first screen SA1 (FIG. 6) of the presentation material is transmitted to the presenter terminal 50 in response to the start command. The screen SA1 (FIG. 6) is displayed on the display unit of the presenter terminal 50. The data management device 10 detects the start of the presentation by receiving the start command.

  The presenter PA can use the screen SA (SA1, SA2,...) (See FIGS. 6 and 7) displayed on the presenter terminal 50 to advance the presentation while changing the display page.

  The presenter PA can select a desired page of the presentation material as a display target page by an operation described later. On the screen SA (SA1, SA2), the selected thumbnail image MN is surrounded by a thick line to indicate the selection status of the display target page. In addition, an image related to the text BT related to the currently selected page is displayed in the text display area BA in the center of the screen SA. For example, in FIG. 6, the first page of the presentation material is displayed in the text display area BA. In addition, the uppermost thumbnail image (thumbnail image corresponding to the first page) MN is surrounded by a thick line to indicate that the display target page is the first page. Note that an image related to the text BT (BT1, BT2,...) Displayed in the text display area BA is also displayed on the display device 30 via the presenter terminal 50.

  In this embodiment, at the start of the presentation, the data management apparatus 10 automatically selects the text BT1 related to the first page of the presentation material as a display target. Then, the data management device 10 includes the image data of the text BT1 related to the first page, the image data of the comment CT, and the text related to a plurality of pages (for example, the first page to the sixth page) in the vicinity of the first page. For example, thumbnail image data from the text BT1 to the text BT6) is transmitted to the presenter terminal 50. The presenter terminal 50 displays the text display area BA on the display device 30 in the screen SA1.

  FIG. 6 shows a state where the first page of the presentation material is selected in such an initial state. On the screen SA1, the text BT1 related to the first page is displayed in the large text display area BA at the center of the screen, and the comment CT1 of the first page is displayed below the text display area BA. It is displayed in the area CA.

  Thereafter, the presenter PA can change the page to be displayed using the screen SA1 (FIG. 6). Specifically, the second page of the presentation material can be selected as a display target page by pressing a button BN10 ("Next" button) in the screen SA1.

  When the button BN10 is pressed, the presenter terminal 50 transmits a display page update request to the data management apparatus 10 as request data DA. This update request (request data DA) includes page identification information for identifying a display target page. Here, the page identification information is composed of, for example, a page number (for example, “second page”) in the presentation material.

  When receiving the display page update request (request data DA), the data management apparatus 10 executes an update process for updating the display screen in response to the update request.

  Specifically, the data management apparatus 10 determines the image data of the text BT2, the image data of the comment CT2, and a plurality of pages in the vicinity of the second page (here, the first page) of the updated page (here, the second page). To the sixth page) is transmitted to the presenter terminal 50. Note that, as described above, a visually-permitted user is set in each comment sentence CS included in each comment CT. Therefore, the data management apparatus 10 determines that each comment sentence CS included in the comment CT2 is visually recognizable on the presenter terminal 50 before the comment CT2 is transmitted (specifically, “Presenter:” at the beginning). Or a comment sentence CS that does not include a character string indicating a visually-permitted user at the beginning. Then, the data management apparatus 10 transmits only the comment sentence CS determined to be the comment sentence CS visible on the presenter terminal 50 to the presenter terminal 50 as the comment CT2.

  The presenter terminal 50 displays a screen SA2 (FIG. 7) based on the received data. On the screen SA2 in FIG. 7, the received image data are arranged in a predetermined layout. In addition, the screen SA2 shows that the text BT2 related to the second page of the presentation material is selected.

  Thereafter, by repeating the same operation, the presenter PA can advance the presentation while changing the page to be displayed in the text display area BA.

  The presenter PA presses a thumbnail image corresponding to a desired page (specifically, a text BT of the desired page) among a plurality of thumbnail images in the left part of the screen SA, thereby the desired page. Can be determined as the next display target page. Specifically, when a certain thumbnail image (for example, thumbnail image MN5) in the screen SA is selected by a mouse operation, the presenter terminal 50 displays a display request indicating that a page corresponding to the thumbnail image should be displayed. Is transmitted to the data management apparatus 10 as request data DA. Then, when receiving the display request (request data DA), the data management apparatus 10 executes an update process for changing the display screen to the designated screen in response to the display request.

  Each operation as described above is executed by the page display control unit 23 or the like.

  That is, the page display control unit 23 controls the display update operation for outputting the page image of each page of the presentation material to the presenter terminal 50 or the like. Specifically, when the presenter PA operates the presenter terminal 50, a display request for each page image (request for updating the text of each page) (request data DA) is sent from the presenter terminal 50 to the data management device 10. Sent. When receiving the display request (request data DA), the page display control unit 23 of the data management apparatus 10 transmits the data of each page image to the presenter terminal 50 in response to the display request (request data DA). . Then, by transmitting the data to the presenter terminal 50, a desired page is displayed on the display device 30.

<1-2-4. Audience terminal display update operation>
After the start of the presentation, the present system 100 can perform the display update operation of the listener terminal in parallel with the display update operation of the presenter terminal as described above. The display update operation of the listener terminal is realized by communication between each listener terminal 70 and the data management device 10.

  Each audience of the presentation (eg, users UA, UB, UC,...) Uses the audience terminals 70 (auditor terminals 70A, 70B, 70C) to relate to presentation materials for presentation during the presentation. View related information. More specifically, each listener of the presentation visually recognizes the related information using application software (hereinafter also simply referred to as an application) AP installed in each listener terminal 70.

  Specifically, a listener (for example, user UA) who desires to browse (view) related information related to the presentation material activates the application AP and performs user authentication. When the application AP is activated, a user authentication display screen SB0 is displayed as shown in FIG.

  Then, the user UA inputs his / her user information (user ID and password) using the operation input unit 76 of the listener terminal 70 and then inputs an OK (decision) instruction. In response to the input, the listener terminal 70 transmits the input user information (user authentication information) to the data management apparatus 10.

  When the data management apparatus 10 receives the user authentication information from the listener terminal 70, the data management apparatus 10 performs an authentication operation. Specifically, in the data management device 10, the combination of user ID and password (input data) matches the combination of user ID and password (regular data) stored in the data management device 10 in advance. Is determined as “authentication successful”. On the other hand, the data management apparatus 10 determines “authentication failure” when the input data does not match the regular data. Then, the data management device 10 returns an authentication result (authentication success or authentication failure) to the listener terminal 70.

  When the authentication result received from the data management apparatus 10 is authentication failure, the listener terminal 70 displays on the display unit 77 that authentication has failed. On the other hand, when the authentication result is successful, the listener terminal 70 displays the display screen SB1 of the application AP on the display unit 77 (see FIGS. 13 to 16).

  More specifically, as shown in FIG. 13, a display area AD for displaying image data GD (GD1, GD2) is arranged on the right side in the display screen SB1.

  Further, on the upper left side in the display screen SB1, buttons BN1, BN2, and BN3 for selecting the display mode MD1 of the image data GD1 and buttons BN4 and BN5 for selecting the display mode MD2 of the image data GD2 are arranged vertically. Is done.

  The user UA determines the display mode MD1 of the image data GD1 by selecting any one of the buttons BN1, BN2, and BN3 (see FIGS. 13 to 15).

  Specifically, the user UA determines the display mode MD1 to be “text mode” (described later) by selecting the button BN1 (see FIG. 13). In addition, the user UA selects the display mode MD1 as “synchronous mode” (described later) by selecting the button BN2 (see FIG. 14), and selects the display mode MD1 as “asynchronous mode” (described later) by selecting the button BN3. (See FIG. 15). Note that these buttons BN1 to BN3 are exclusively processed, and the user UA can select only one of the buttons BN1 to BN3.

  Further, the user UA selects one of the buttons BN4 and BN5 to determine the display mode MD2 of the image data GD2 (see FIG. 16).

  Specifically, the user UA selects the display mode MD2 as a synchronous mode (described later) by selecting the button BN4, and determines the display mode MD2 as an asynchronous mode (described later) by selecting the button BN5.

  Note that these buttons BN4 and BN5 may function as valid buttons or may not function as invalid buttons depending on the selection of the buttons BN1 to BN3.

  Specifically, during the selection of the button BN1, both the buttons BN4 and BN5 can be selected as valid buttons. However, exclusive processing is performed on the buttons BN4 and BN5 at this time, and the user UA can select one of the buttons BN4 and BN5.

  While the button BN2 is selected, the button BN5 can be selected as a valid button, but the button BN4 cannot be selected as an invalid button (see FIG. 14). At this time, the button BN4 is displayed as a disabled button with a dotted line.

  While the button BN3 is selected, the button BN4 can be selected as a valid button, but the button BN5 cannot be selected as an invalid button (see FIG. 15). At this time, the button BN5 is displayed as a disabled button with a dotted line.

  Here, “text mode”, “synchronous mode”, and “asynchronous mode” will be described.

  The “text mode” is a mode in which an image related to the text BT related to the display target page is displayed as image data GD in the display area AD (see FIG. 13).

  The “synchronous mode” is a mode in which an image related to a related material file related to the display target page is displayed as image data GD in the display area AD (see FIG. 14).

  The “asynchronous mode” is a mode in which an image related to the related material file selected by the listener is displayed as image data GD in the display area AD (see FIG. 15).

  By the way, the user UA also determines the display format DF (one image display format DF1, two image display formats DF2) of the image data GD by selecting the buttons BN1 to BN5. The one-image display format DF1 is a display format in which the image data GD1 is displayed as the image data GD in the display area AD (FIGS. 13 to 15). On the other hand, the two-image display format DF2 is a display format in which the image data GD1 and the image data GD2 are displayed side by side as image data GD in the display area AD (see FIG. 16).

  Specifically, the user UA selects any one of the buttons BN1 to BN3 and decides the display format DF to be “one image display format DF1” by not selecting any of the buttons BN4 and BN5. . In addition, the user UA selects any one of the buttons BN1 to BN3 and selects any one of the buttons BN4 and BN5 to determine the display format DF as “two-image display format DF2”.

  A box BX1 and a box BX2 are arranged on the lower left side in the display screen SB1 of the application AP. A list of thumbnail images of related material files that can be selected in the synchronous mode is displayed in the box BX1. In the box BX2, a list of thumbnail images of related material files that can be selected in the asynchronous mode is displayed.

  Specifically, when the synchronization mode is selected by the user UA, the listener terminal 70 transmits an update request for the box BX1 to the data management apparatus 10.

  In response to the received update request, the data management device 10 generates a thumbnail image of the related material file that can be selected in the synchronous mode, and transmits the thumbnail image to the listener terminal 70.

  Specifically, the display target page acquisition unit 26 acquires a display target page that is a page currently displayed on the display device 30 during the presentation from among a plurality of pages included in the presentation material. Specifically, the display target page acquisition unit 26 acquires the display target page based on the page identification information included in the request data DA. Thereafter, the related information extraction unit 27 relates to the display target page (specifically, the text BT of the display target page) among the plurality of related material files stored in the related material file storage unit 6a. Is extracted as a page-related file. Then, the image data generation unit 29 generates a thumbnail image related to the page-related file (for example, the first page thumbnail image). When the thumbnail image of the page-related file is generated, the communication unit 4 transmits the thumbnail image to the listener terminal 70. Thereafter, the listener terminal 70 displays the received thumbnail image in the box BX1 as shown in FIG.

  In the asynchronous mode, the listener terminal 70 transmits an update request for the box BX2 to the data management apparatus 10.

  Thereafter, in response to the received update request, the data management device 10 generates a thumbnail image of the related material file that can be selected in the asynchronous mode, and transmits the thumbnail image to the listener terminal 70.

  Specifically, in response to the update request, the image data generation unit 29 generates thumbnail images related to all the related material files stored in the related material file storage unit 6a. When the thumbnail image is generated, the communication unit 4 transmits the thumbnail image to the listener terminal 70. Thereafter, the listener terminal 70 displays the received thumbnail image in the box BX2, as shown in FIG.

  The user UA can select thumbnail images to be displayed in the box BX1 and the box BX2 by using the operation input unit 76 of the listener terminal 70.

  Specifically, when a thumbnail image displayed in the boxes BX1 and BX2 is selected by the user UA, the selected thumbnail image is surrounded by a thick line as shown in FIGS.

  In such a display screen SB1, the user UA can select the display format DF, the display mode MD, the related material file in the synchronous mode, and the related material file in the asynchronous mode.

  In addition, when the display screen SB1 is operated by the user UA, the listener terminal 70 generates a request data DB (see FIG. 11) and transmits the request data DB to the data management apparatus 10. The data management device 10 generates display data (specifically, image data GD) on the listener terminal 70 (specifically, the display area AD) based on the request data DB.

  As shown in FIG. 11, the request data DB includes display format information FI, display mode information MI1, MI2, and selected file information SI1, SI2.

  The display format information FI includes identification information (for example, one image display format DF1 or two image display format DF2) for identifying the display format DF.

  The display mode information MI1 includes identification information (for example, a text mode, a synchronous mode, and an asynchronous mode) for identifying the display mode MD1 of the image data GD1. Further, the display mode information MI2 includes identification information (for example, synchronous mode, asynchronous mode) for identifying the display mode MD2 of the image data GD2.

  The selected file information SI1, SI2 includes identification information (for example, file name) for identifying the related material file.

  When the “text mode” is selected as the display mode MD1 in the one-image display format DF1, the data management device 10 is the page being displayed on the display device 30 in the presentation among the plurality of pages included in the presentation material. Specify the display target page. Then, the data management apparatus 10 transmits display data (specifically, image data GD) of the display target page to the listener terminal 70.

  In addition, when “synchronous mode” is selected as the display mode MD1 in the one-image display format DF1, the data management device 10 displays a page that is being displayed on the display device 30 in the presentation among a plurality of pages included in the presentation material. The display target page is specified. Then, the data management device 10 transmits display data (specifically, image data GD) related to the page related file related to the display target page to the listener terminal 70 as related information.

  The data management apparatus 10 also relates to the related material designated by the listener among at least one related material file related to the presentation material when “asynchronous mode” is selected as the display mode MD1 in the one-image display format DF1. Display data (specifically, image data GD) of the specified file that is a file is transmitted to the listener terminal 70 as related information.

  In addition, in the two-image display format DF2, the data management apparatus 10 specifies the display target page when “text mode” is selected as the display mode MD1 and “synchronous mode” is selected as the display mode MD2. The page related information related to the display target page is also specified. Then, the data management apparatus 10 sends the display data (specifically, image data GD1) of the display target page and the display data (specifically, image data GD2) related to the page-related file to the listener terminal 70. Send.

  In addition, in the two-image display format DF2, the data management apparatus 10 specifies a display target page when “text mode” is selected as the display mode MD1 and “asynchronous mode” is selected as the display mode MD2. The specified file which is the related material file specified by the listener is also specified. Then, the data management device 10 transmits the display data (specifically, image data GD1) of the display target page and the display data (specifically, image data GD2) related to the designated file to the listener terminal 70. To do.

  In addition, in the two-image display format DF2, the data management apparatus 10 specifies a page-related file when “synchronous mode” is selected as the display mode MD1 and “asynchronous mode” is selected as the display mode MD2. Also specify the specified file. Then, the data management device 10 transmits display data for the page-related file (specifically, image data GD1) and display data for the specified file (specifically, image data GD2) to the listener terminal 70. To do. The data management apparatus 10 is the same when the “asynchronous mode” is selected as the display mode MD1 and “asynchronous mode” is selected as the display mode MD2 in the two-image display format DF2. The operation shall be performed.

  Below, operation | movement of such a data management apparatus 10 is demonstrated in detail, referring FIGS. 8-10.

  The operation in the data management apparatus 10 is executed at the timing when the request data DA is received from the presenter terminal 50 and at the timing when the request data DB is received from the listener terminal 70. The request data DA and DB are temporarily stored in the data management device 10 and updated when each data is received. Then, the data management apparatus 10 operates based on the request data DA and the request data DB. For example, when the request data DA is received from the presenter terminal 50, the data management apparatus 10 updates the request data DA that has been received and stored before that time. The data management apparatus 10 operates based on the updated request data DA and the request data DB received and stored before that.

  First, in step S21 (FIG. 8), the data management apparatus 10 executes image data GD1 generation processing (described later).

  In step S22, whether or not the display format DF is the two-image display format DF2 is determined based on the request data DB.

  If it is determined in step S22 that the display format DF is not the two-image display format DF2, the process proceeds to step S25. In step S25, the data management apparatus 10 determines that the display format DF is the one-image display format DF1, and transmits the image data GD1 generated by the generation processing of the image data GD1 to the listener terminal 70 as the image data GD.

  If it is determined in step S22 that the display format DF is the two-image display format DF2, the data management device 10 executes a process for generating image data GD2 (described later) (step S23). Then, the data management device 10 transmits to the listener terminal 70 the image data GD obtained by combining the image data GD1 generated by the generation processing of the image data GD1 and the image data GD2 by the generation processing of the image data GD2.

  Next, the generation process (step S21) of the image data GD1 will be described in detail with reference to the flowchart of FIG.

  The image data generation unit 29 specifies the display mode MD1 of the image data GD1 based on the display mode information MI1 of the request data DB (Step S51).

  In step S51, when the display mode MD1 is specified as the “text mode”, the display target page acquisition unit 26 specifies and acquires the display target page that is being displayed on the display device 30 in the presentation. . Specifically, the display target page acquisition unit 26 specifies the display target page based on the page identification information included in the request data DA. Then, the image data generation unit 29 generates an image related to the text BT related to the display target page as the image data GD1 (step S52).

  When the display mode MD1 is specified as “synchronous mode” in step S51, the display target page acquisition unit 26 specifies and acquires the page corresponding to the page image displayed on the display device 30 as the display target page. To do. Then, the related information extraction unit 27 determines whether or not there is a related material file (“page related file”) related to the display target page (specifically, the text BT of the display target page) (step) S53).

  If it is determined that a page related file exists in the display target page, the related information extraction unit 27 extracts a page related file related to the display target page based on the selected file information SI1. When a plurality of related document files (page related files) are related to the display target page, the page related file selected from the plurality of page related files according to an appropriate standard (in this case, in the order of file names) May be extracted. When a plurality of related material files (page related files) are related to the display target page, a page related file designated by the listener is extracted from the plurality of page related files. May be.

  When the page related file is extracted in this way, the image data generating unit 29 generates an image related to the page related file (for example, a page image related to the page related file) as the image data GD1 (step S54).

  On the other hand, when it is determined that there is no related material file related to the display target page (specifically, the text BT of the display target page), the image data generation unit 29 generates a blank paper image as the image data GD1. (Step S55).

  When the display mode MD1 is specified as “asynchronous mode” in step S51, the related information extraction unit 27 selects the user UA from at least one related material file related to the presentation material based on the selected file information SI1. The related material file specified by (listener) is extracted as the specified file. Then, the image data generation unit 29 generates the page image of the designated file as the image data GD1 (Step S56).

  Next, the generation process (step S23) of the image data GD2 will be described in detail with reference to the flowchart of FIG.

  The image data generation unit 29 specifies the display mode MD2 of the image data GD2 based on the display mode information MI2 (Step S71).

  When it is specified in step S71 that the display mode MD2 is the synchronous mode, processes similar to the processes in steps S53, S54 and S55 of FIG. 9 are executed in steps S72, S73 and S74. Image data GD2 is generated.

  If it is determined in step S71 that the display mode MD2 is the asynchronous mode, in step S75, processing similar to that in step S56 in FIG. 9 is executed, and image data GD2 is generated.

  As described above, the data management device 10 transmits the image data GD to the listener terminal 70 as display data on the listener terminal 70 (steps S24 and S25 in FIG. 8).

  When receiving the image data GD, the listener terminal 70 displays the image data GD in the display area AD of the display screen SB1.

  According to the above operation, for example, the user UA (listener) associates a “page related file” that is a related material file related to a display target page (a page being displayed in a presentation) in “synchronous mode”. Information can be visually recognized on the listener terminal 70 (see FIGS. 14 and 16). Further, by using the “synchronous mode” and the “text mode” in combination (see FIG. 16), the listener can view the page to be displayed while viewing the page-related file as related information on the listener terminal 70. It can be viewed with the terminal 70.

  In addition, in the “asynchronous mode”, the listener visually recognizes the “designated file”, which is a related material file designated by the listener among a plurality of related materials related to the presentation material, on the audience terminal 70 as related information. Is possible (see FIG. 15). Furthermore, by using both the “asynchronous mode” and the “text mode”, the listener can view the display target page on the listener terminal 70 while viewing the “specified file” as related information. Yes (see FIG. 17).

  In addition, by using both the “synchronous mode” and the “asynchronous mode” (see FIG. 18), the audience can visually recognize the specified file on the audience terminal 70 while viewing the page-related file on the audience terminal 70. Is possible.

<2. Second Embodiment>
The second embodiment is a modification of the first embodiment. Below, it demonstrates centering on difference with 1st Embodiment.

  In the first embodiment, a related material file related to a display target page is specified and extracted as related information by the related information extraction unit 27, and the related material file is displayed on the listener terminal 70 as related information. Illustrated.

  In the second embodiment, a comment (comment information) CT associated with a display target page is specified and extracted by the related information extraction unit 27 as related information, and the comment CT is displayed on the listener terminal 70 as related information. The embodiment to be illustrated is illustrated.

  20 to 22 are diagrams showing the display screen SB2 of the application AP in the second embodiment.

  On the right side in the display screen SB2 of the application AP, a display area AD is arranged as in the display screen SB1 of the application AP in the first embodiment.

  Further, buttons BN6, BN7, and BN8 for selecting the display mode MD of the image data GD are arranged on the upper left side in the display screen SB2 of the application AP.

  As shown in FIG. 20, the user UA selects one of the buttons BN6, BN7, and BN8 to change the display mode MD into three modes (text mode, comment mode, text / comment mode) ( One of the modes described later).

  Note that these buttons BN6 to BN8 are exclusively processed, and the user UA can select only one of the buttons BN6 to BN8. For example, when the button BN6 is selected, the button BN6 is surrounded by a thick line and is in a selected state (FIG. 20). Here, when the user UA selects a button other than the button BN6 (for example, the button BN7), the selection of the button BN6 is canceled, and the selected button (BN7) is selected by being surrounded by a thick line (FIG. 21). ).

  The user UA can update the image data GD to be displayed in the display area AD by appropriately selecting these buttons BN6 to BN7.

  Specifically, when any one of the buttons BN6 to BN7 is selected, the listener terminal 70 transmits request data DC (not shown) corresponding to the selected button to the data management apparatus 10. . The request data DC includes mode identification information for identifying the display mode MD (text mode, text / comment mode, comment mode).

  When the “text mode” is selected as the display mode MD, the data management device 10 specifies a display target page that is a page currently displayed on the display device 30 in the presentation among a plurality of pages included in the presentation material. . Then, the data management apparatus 10 transmits display data (specifically, image data GD) of the display target page to the listener terminal 70.

  Further, when “text / comment mode” is selected as the display mode MD, the data management device 10 displays a display target that is a page being displayed on the display device 30 in the presentation among a plurality of pages included in the presentation material. Identify the page. In addition, the data management apparatus 10 identifies and extracts comment information associated with the display target page as related information. Then, the data management device 10 transmits the display data of the display target page and the comment information to the listener terminal 70.

  In addition, when “comment mode” is selected as the display mode MD, the data management device 10 specifies the display target page and also extracts the comment information associated with the display target page as related information. To do. Then, the data management apparatus 10 transmits the comment information to the listener terminal 70.

  Below, operation | movement of such a data management apparatus 10 is demonstrated in detail, referring FIG. FIG. 19 is a flowchart showing the operation of the data management apparatus 10 in the second embodiment.

  The operation in the data management apparatus 10 is executed at the timing when the request data DA is received from the presenter terminal 50 and at the timing when the request data DC is received from the listener terminal 70. The request data DA and DC are temporarily stored in the data management device 10 and updated when each data is received.

  First, the display target page acquisition unit 26 specifies and acquires a display target page that is a page being displayed on the display device 30 in the presentation (step S31). Specifically, the display target page acquisition unit 26 specifies the display target page based on the page identification information included in the request data DA.

  Next, the image data generation unit 29 identifies the display mode MD (text mode, text / comment mode, comment mode) based on the request data DC (step S32).

  When the display mode MD is identified as the “text mode”, the image data generation unit 29 generates image data GD related to the text BT related to the display target page (step S33).

  When the display mode MD is identified as the “text / comment mode”, the related information extraction unit 27 relates the comment CT related to the display target page (specifically, the text BT related to the display target page). It identifies and extracts as information (step S34). At this time, the related information extraction unit 27 detects a visually-permitted user set in each comment sentence CS included in the comment CT. Then, the related information extraction unit 27 extracts only the comment text CS that can be viewed on the listener terminal 70 (that is, the comment text CS that can be viewed by the listener) as the comment CT. Thereafter, the image data generation unit 29 generates image data GD obtained by combining the image of the text BT related to the display target page and the image of the comment CT associated with the text BT (step S35).

  When the display mode MD is identified as the “comment mode”, the related information extraction unit 27 is associated with the display target page (specifically, the text BT related to the display target page) in the same manner as in step S34. The comment CT is specified and extracted as related information (step S36). Thereafter, the image data generation unit 29 generates a comment image of the comment CT associated with the text BT related to the display target page as the image data GD.

  Note that when there is no comment CT associated with the display target page (specifically, the text BT related to the display target page) (the comment sentence CS included in the comment CT can be visually recognized by the listener terminal 70). The related information extraction unit 27 cannot extract the comment CT in step S34 and step S36. Therefore, the image data generation unit 29 generates an image of the text BT related to the display target page as the image data GD.

  When the image data GD is generated, the communication unit 4 transmits the image data GD to the listener terminal 70 as display data on the listener terminal 70 (step S38).

  Upon receiving the image data GD, the listener terminal 70 displays the image data GD in the display area AD.

  According to such an operation, when the “text mode” is selected on the listener terminal 70, an image related to the text BT of the display target page is displayed in the display area AD (see FIG. 20).

  When “comment mode” is selected on the listener terminal 70, an image related to the comment CT associated with the display target page is displayed in the display area AD (see FIG. 21). Accordingly, the listener can visually recognize the comment CT associated with the display target page on the listener terminal 70 as related information.

  When the “text / comment mode” is selected on the listener terminal 70, a composite image obtained by combining the image related to the text BT and the image related to the comment CT is displayed in the display area AD (see FIG. 22). Therefore, the audience can visually recognize the comment CT associated with the display target page as related information on the audience terminal 70 while viewing the display target page on the audience terminal 70.

<3. Modified example>
Although the embodiments of the present invention have been described above, the present invention is not limited to the contents described above.

  For example, in the first embodiment, the related material file related to the display target page is specified and extracted by the related information extracting unit 27 as related information, and the related material file is displayed on the listener terminal 70 as related information. The embodiment was illustrated. In the second embodiment, the comment (comment information) CT associated with the display target page is specified and extracted as related information by the related information extraction unit 27, and the comment CT is used as related information. The mode displayed at 70 is illustrated.

  However, the present invention is not limited to these. Specifically, in the system of the first embodiment, “comment information” may also be displayed on the listener terminal 70. More specifically, the related information extraction unit 27 specifies and extracts a related material file related to the display target page, and specifies and extracts a comment (comment information) CT associated with the display target page, Both the related material file and the comment CT may be displayed on the listener terminal 70 as related information.

  This check box CB is used as a check box for selecting whether or not to display an image related to the comment CT associated with the text BT as image data GD1 together with an image related to the text BT of the display target page. The user UA can switch ON (no check) / OFF (check) of the check box CB by a mouse operation or the like.

  For example, as shown in the display screen SB3, the listener selects the “text mode” as the display mode MD1 and the “synchronous mode” as the display mode MD2 in the two-image display format DF2, and checks the check box CB. Turn on.

  When the check box CB is ON, a composite image of an image related to the body text BT of the display target page and an image related to the comment CT is displayed as image data GD1 in the upper area of the display area AD, and an image related to the page related file is displayed as image data. It is displayed in the lower area of the display area AD as GD2. Specifically, a composite image of the image data GD1 and the image data GD2 is generated by the data management device 10 as the image data GD and transmitted to the listener terminal 70. The listener terminal 70 can display a screen as shown in FIG. 23 by using the image data GD transmitted from the data management device 10.

  According to this, the listener visually recognizes the display target page (including the text BT and the comment CT) on the listener terminal 70 and also the related material file related to the display target page as the related information on the listener terminal 70. can do.

  When the check box CB is OFF, the listener terminal 70 receives only the image related to the text BT of the display target page as the image data GD1, and displays the same content as FIG.

  In addition, here, the “synchronous mode” and “comment display” are combined to display the “page related file” and the comment information on the audience terminal 70 as related information. However, the present invention is not limited to this. For example, “asynchronous mode” and “comment display” may be combined to display “specified file” and comment information on the listener terminal 70 as related information.

  Further, in each of the above embodiments, the case where the page related file related to the text BT is specified from the files stored in the related material file storage unit 6a is illustrated, but the present invention is not limited to this.

  For example, a page-related file related to the body text BT is specified from a plurality of files existing in a location different from the related material file storage unit 6a (for example, a predetermined server existing outside the data management apparatus 10). You may do it. The material analysis unit 25 may acquire the specified page related file via the network and store it in the related material file storage unit 6a.

  FIG. 24 is a diagram showing such a modification. In the modified example, the presenter relates to the text BT as a character string surrounded by identifiers “<”, “>” in the text BT of the presentation material as shown in the texts TX3 and TX4 in FIG. Write text information indicating the location of the external file (related information). The text TX3 in FIG. 24 represents the URL of the external device, and the text TX4 in FIG. 24 represents the file name to which the directory structure information in the external computer is added. Then, the material analysis unit 25 specifies the location of the related information (related material file) based on the texts TX3 and TX4, acquires the related information via the network, and stores it in the related material file storage unit 6a. To do. Such a storing operation is preferably executed before the presentation starts, but may be executed during the presentation.

  More specifically, the material analysis unit 25 refers to the text TX4 of the body text BT, identifies a file in a predetermined folder in the external computer (computer name “server”) as a page-related file, and identifies the file on the network. Through the related material file storage unit 6a.

  In addition, the material analysis unit 25 refers to the text TX3 of the body text BT and generates a data file (for example, an HTML file and an image file) for reproducing a web page corresponding to the URL described in the text TX3 as a page-related file. The data file is acquired via the network and stored in the related material file storage unit 6a.

  As described above, the information regarding the storage destination of the external data can be described by directory structure information (external computer address information or the like) and / or web address information (URL information or the like).

  In each of the above embodiments, the data management device 10 generates image data GD related to related information (related material file and / or comment CT), and uses the image data GD as display data for related information. Although the case where it transmits to the terminal 70 was illustrated, it is not limited to this.

  For example, the data management apparatus 10 may transmit the data of the related information (comment CT and / or related material file) itself to the listener terminal 70 as display data. Then, the listener terminal 70 generates image data GD related to the related information to be displayed in the display area AD based on the related information (comment CT and / or related material file) received from the data management device 10. Also good.

  In each of the above embodiments, the data management apparatus 10 uses the symbols “<” and “>” included in the body text BT as identifiers, and specifies related information for a character string surrounded by the identifiers. Although the case where it recognizes as a character string for doing was illustrated, it is not limited to this.

  For example, the data management apparatus 10 uses a predetermined keyword (for example, “reference material:”, “source:” (see FIG. 20), etc.) included in the text BT as an identifier, and follows the identifier (predetermined keyword). The character string may be recognized as a character string for specifying related information.

  Further, the data management device 10 uses the symbol “<” and the symbol “>” included in the body text BT as the first identifier, and sets the predetermined keyword included in the character string enclosed by the first identifier to the first A character string for identifying related information may be used as an identifier of 2. More specifically, the data management device 10 uses the first identifier to extract a character string that includes a character string for specifying related information, and the second character string among the extracted character strings. A character string following the identifier may be recognized as a character string for specifying related information.
