  Next, the operation in this presentation support system will be described with reference to FIGS. Here, the listener terminal registration process, the presentation support process, the page change control process, the related material control process, and the presentation end process are performed in this order.

(Auditor terminal registration process)
First, the listener terminal registration process will be described with reference to FIG. This process is performed before the presentation starts. Here, the slide material file, the related material file, and the audio file used for the presentation are downloaded in advance from the management server 30 to the listener terminal 10. Also, the slide material file and the related material file are downloaded to the explainer terminal 20.

  And the control part 21 of the instructor terminal 20 performs the acquisition process of peripheral terminal information (step S1-1). Specifically, the communication control unit 211 of the control unit 21 transmits a connection request via the wireless communication unit 26. Here, the listener terminal 10 that has received the connection request via the wireless communication unit 16 returns a terminal identifier to the explainer terminal 20.

  Next, the control unit 21 of the explainer terminal 20 executes display processing of peripheral terminal information (step S1-2). Specifically, the communication control unit 211 of the control unit 21 supplies the terminal identifier acquired via the wireless communication unit 26 to the peripheral terminal management unit 212. In this case, the peripheral terminal management unit 212 displays the terminal identifier on the touch panel 23. When there are a plurality of listener terminals 10 around the presenter terminal 20, all terminal identifiers are displayed.

  Next, the control part 21 of the instructor terminal 20 performs the control target terminal designation process (step S1-3). Specifically, the terminal identifier displayed on the touch panel 23 is confirmed, and the listener terminal 10 used for the presentation is selected on the touch panel 23. In this case, the peripheral terminal management unit 212 of the control unit 21 records the specified terminal identifier in the terminal management table 224. Then, the peripheral terminal management unit 212 transmits a pairing request to the listener terminal 10 having the designated terminal identifier via the wireless communication unit 26. The pairing request includes the terminal identifier of the explainer terminal 20.

  The control unit 11 of the listener terminal 10 that has received the pairing request executes an instruction accepting process (step S1-4). Specifically, the communication control means 111 of the control unit 11 stores the terminal identifier of the explainer terminal 20 and performs pairing control that accepts only commands from the explainer terminal 20.

(Presentation support processing)
Next, the presentation support process will be described with reference to FIG. This process is performed during the presentation. In this case, the same slide material file can be opened on the listener terminal 10 and the explainer terminal 20.

  Here, the control unit 21 of the presenter terminal 20 executes a voice acquisition process (step S2-1). Specifically, the presenter utters an instruction to the presenter terminal 20. In this case, the voice recognition unit 213 of the control unit 21 acquires the voice collected by the microphone 24.

  Next, the control part 21 of the instructor terminal 20 performs a speech recognition process (step S2-2). Specifically, the voice recognition means 213 of the control unit 21 converts the acquired voice into text by voice recognition processing. Then, the voice recognition unit 213 supplies the converted text to the instruction conversion unit 214.

  Next, the control part 21 of the instructor terminal 20 performs the conversion process to a command (step S2-3). Specifically, the instruction conversion unit 214 of the control unit 21 searches the command table 223 for the text acquired from the voice recognition unit 213. If the corresponding text is not registered in the command table 223, the processing for this text is terminated. On the other hand, if registered in the command table 223, the instruction conversion unit 214 acquires a command corresponding to the text.

  Next, the control part 21 of the instructor terminal 20 performs a command transmission process (step S2-4). Specifically, the instruction conversion unit 214 of the control unit 21 supplies the acquired command to the communication control unit 211. In this case, the communication control unit 211 acquires the terminal identifier recorded in the terminal management table 224. And the communication control means 211 transmits the instruction | indication including a command with respect to the listener terminal 10 of this terminal identifier via the wireless communication part 26. FIG.

Here, for commands relating to slides, the instruction conversion unit 214 performs display control according to the commands for the slides displayed on the touch panel 23. Thereby, the current page is also displayed on the touch panel 23 of the presenter terminal 20 by synchronizing the touch panel 23 of the presenter terminal 20 and the touch panel 13 of the listener terminal 10. For example, when voice recognition is performed for “next page”, the instruction conversion unit 214 specifies the current page of the currently displayed slide, and specifies the next page as a new current page. The instruction conversion unit 214 generates a command for changing the slide of the listener terminal 10 to the current page.

  The control unit 11 of the listener terminal 10 that has received the instruction executes command reception processing (step S2-5). Specifically, the communication control unit 111 of the control unit 11 takes over the command to the instruction control unit 112. In this case, the instruction control unit 112 takes over the command to the display control unit 113 or the audio output control unit 114 according to the application identifier of the command.

  When the application identifier is “slide”, the control unit 11 of the listener terminal 10 executes display control processing (step S2-6). Specifically, the display control unit 113 of the control unit 11 outputs the slide page of the slide material file 121 in response to the command.

  On the other hand, when the application identifier is “speech”, the control unit 11 of the listener terminal 10 executes speech synthesis output processing (step S2-7). Specifically, the audio output control means 114 of the control unit 11 reproduces the audio file 123 in response to the command.

(Page change control process)
Next, the page change control process will be described with reference to FIG. Here, it is assumed that the voice of “next page” is input at the presenter terminal 20. In this case, the explainer terminal 20 transmits a command for setting the slide to the next page to the listener terminal 10.

  Here, the control unit 11 of the listener terminal 10 executes a command reception process (step S3-1). Specifically, the communication control unit 111 of the control unit 11 takes over the command received from the explainer terminal 20 to the instruction control unit 112. The instruction control unit 112 takes over the command to the display control unit 113.

  Next, the control unit 11 of the listener terminal 10 executes a current page specifying process (step S3-2). Specifically, the display control unit 113 of the control unit 11 specifies the display designation current page included in the command.

  Next, the control unit 11 of the listener terminal 10 executes a current page update process (step S3-3). Specifically, the display control means 113 of the control unit 11 records a possible flag in the browsing control flag data area.

  Next, the control unit 11 of the listener terminal 10 executes current page display processing (step S3-4). Specifically, the display control unit 113 of the control unit 11 outputs the identified slide of the current page to the touch panel 13.

  Next, the control unit 11 of the listener terminal 10 executes display history recording processing (step S3-5). Specifically, the display control means 113 of the control unit 11 additionally records the file name and browsing page of the slide material file 121 in the browsing history file 124 in association with the current time.

Next, processing when the listener wishes to view a slide page different from the current page will be described. In this case, page turning input is performed using the touch panel 13.
In this case, the control unit 11 of the listener terminal 10 executes a page change instruction process (step S3-6). Specifically, the display control unit 113 of the control unit 11 specifies the page change direction (advance and return) according to the touch state (touch position and movement) on the touch panel 13.

  Next, the control unit 11 of the listener terminal 10 executes an acquisition process of the change-destination browsing control information (step S3-7). Specifically, the display control means 113 of the control unit 11 confirms the browsing control flag data area of the slide page in the designated direction.

  Next, the control part 11 of the listener terminal 10 performs the determination process about whether it is a browsing possible page (step S3-8). Specifically, the display control means 113 of the control unit 11 makes a determination based on the possible flag in the browsing control flag data area. When the possible flag is acquired, it is determined as a browsable page. On the other hand, when the possible flag is not recorded, it is determined that the page cannot be viewed.

  When it is determined that the page is not a browsable page (in the case of “NO” in step S3-8), the control unit 11 of the listener terminal 10 executes a browsing impossible process (step S3-9). Specifically, the display control unit 113 of the control unit 11 outputs a message indicating that browsing cannot be performed on the touch panel 13.

When it is determined that the page can be viewed (in the case of “YES” in step S3-8), the control unit 11 of the listener terminal 10 executes a display process of the changed page (step S3-10). Specifically, the display control unit 113 of the control unit 11 outputs the designated slide page to the touch panel 13.
And the control part 11 of the listener terminal 10 performs the recording process of a display history similarly to step S3-5 (step S3-11).

(Related data control processing)
Next, the related document control process will be described with reference to FIG. This process is executed when a new slide page is displayed in the slide material.

  Here, the control unit 11 of the listener terminal 10 executes a current page change detection process (step S4-1). Specifically, the display control unit 113 of the control unit 11 detects a change in the current page based on a command acquired from the explainer terminal 20.

  Next, the control part 11 of the listener terminal 10 performs the specific process of the related material which cannot be browsed (step S4-2). Specifically, the display control means 113 of the control unit 11 identifies a file in which the inability flag is recorded in the browsing control flag data area in the related material file 122 recorded in the data storage unit 12. Note that the viewable file in which the possible flag is recorded in the view control flag data area is maintained as it is.

Then, the following processing is repeated for each identified related material that cannot be browsed.
Here, first, the control unit 11 of the listener terminal 10 executes browsing condition acquisition processing (step S4-3). Specifically, the display control unit 113 of the control unit 11 acquires the viewing conditions of the related material file 122.

  And the control part 11 of the listener terminal 10 performs the determination process about whether browsing conditions are satisfy | filled (step S4-4). For example, when the number of pages of the slide material is set as the viewing condition, the display control unit 113 of the control unit 11 compares the current page with the condition page recorded as the viewing condition. If the current page is equal to or greater than the condition page, it is determined that browsing is possible.

  When it determines with satisfy | filling browsing conditions (in the case of "YES" in step S4-4), the control part 11 of the listener terminal 10 performs a change process so that browsing is possible (step S4-5). Specifically, the display control means 113 of the control unit 11 records a possible flag in the browsing control flag data area of the related material file 122. And the display control means 113 changes the selection button of a related material in the touch panel 13 so that selection is possible.

  On the other hand, if it is determined that the viewing conditions are not satisfied (in the case of “NO” in step S4-4), the processing for this related material is terminated. The above processing is repeated for all related materials that cannot be viewed.

(Presentation end processing)
Next, the presentation end process will be described with reference to FIG. This process is executed when the presentation is finished.

  First, the control unit 21 of the presenter terminal 20 executes a presentation end process (step S5-1). Specifically, the voice recognition unit 213 of the control unit 21 acquires “explanation” and “end” voices, and executes voice recognition processing. In this case, the instruction conversion unit 214 converts the speech-recognized text into a presentation end command and transmits it to the explainer terminal 20.

  The control unit 11 of the listener terminal 10 that has received the presentation end command executes a questionnaire input process (step S5-2). Specifically, the display control unit 113 of the control unit 11 outputs a questionnaire screen to the touch panel 13 using the questionnaire file 125. In this questionnaire screen, when the listener inputs various answers using the touch panel 13, the display control unit 113 records the input content in the questionnaire file 125. When the display control means 113 of the control unit 11 detects the selection of the completion button on the questionnaire screen, it ends the questionnaire input process.

  Next, the control unit 11 of the listener terminal 10 executes a questionnaire registration process (step S5-3).

  (3) In the above embodiment, in the page change control process, the control unit 11 of the listener terminal 10 executes the current page update process (step S3-3). Then, in the page change instruction process (step S3-6), the control unit 11 of the listener terminal 10 obtains the change-destination browsing control information (step S3-7), and determines whether the page is a browsable page. Is executed (step S3-8). Thereby, in a presentation, browsing about the slide which has not been explained yet can be controlled. On the other hand, the already explained slides can be reviewed later.

  (4) In the above embodiment, in the related material control process, the control unit 11 of the listener terminal 10 executes a determination process as to whether or not the viewing condition is satisfied (step S4-4). When it determines with satisfy | filling browsing conditions (in the case of "YES" in step S4-4), the control part 11 of the listener terminal 10 performs a change process so that browsing is possible (step S4-5). Thereby, browsing of the related material regarding the slide which has not been explained in the presentation can be suppressed.

  (5) In the above embodiment, in the presentation end process, the control unit 11 of the listener terminal 10 executes a questionnaire input process (step S5-2). And the control part 11 of the listener terminal 10 performs the registration process of a questionnaire (step S5-3). Thereby, the evaluation information of the listener for the presentation can be acquired.

  (6) In the above embodiment, in the page change control process, the control unit 11 of the listener terminal 10 executes a display history recording process (steps S3-5 and S3-11). Then, in the presentation end process, the control unit 11 of the listener terminal 10 executes a browsing history registration process (step S5-4). As a result, it is possible to confirm which slide the listener was viewing.

  (7) In the above embodiment, in the presentation end process, the control unit 11 of the listener terminal 10 executes a file deletion process (step S5-5). Thereby, even when a plurality of different listeners share the listener terminal 10, unnecessary files can be deleted and information management can be performed accurately.

In addition, you may change the said embodiment into the following aspects.
In the above embodiment, in the presentation end process, the control unit 11 of the listener terminal 10 executes a file deletion process (step S5-5). The timing of deleting the material is not limited to this. For example, the control unit 11 of the listener terminal 10 may calculate the elapsed time from the end of the presentation, and delete the file when the reference time has elapsed.

In the above embodiment, the presenter changes the slide as the presentation progresses. In this case, the slide displayed on the listener terminal 10 is controlled based on an instruction from the explainer terminal 20. Here, the presenter terminal 20 may be able to grasp the slide viewing status on the listener terminal 10. In this case, the browsing status file is recorded in the data storage unit 22. In this browsing status file, a slide page (browsing page) browsed in each terminal is recorded in association with the terminal identifier of each listener terminal 10. In addition, the control unit 21 of the presenter terminal 20 is provided with browsing status management means. The browsing status management process in this browsing status management means will be described with reference to FIG.

  The control unit 21 of the explainer terminal 20 executes a process for collecting current browsing page information (step S6-1). Specifically, the listener terminal 10 transmits browsing status information to the explainer terminal 20 when the slide page is changed. The browsing status information includes the terminal identifier of the listener terminal 10 and data related to the slide page being browsed. In this case, the browsing status management means of the control unit 21 acquires browsing status information from the listener terminal 10 via the wireless communication unit 26.

  Next, the control unit 21 of the presenter terminal 20 executes a browsing status information recording process (step S6-2). Specifically, the browsing status management means of the control unit 21 updates the browsing page associated with the terminal identifier in the browsing status file.

  Next, the control part 21 of the instructor terminal 20 performs the statistical process of a browsing page (step S6-3). Specifically, the browsing status management means of the control unit 21 calculates the number of viewers for each browsing page using the browsing status file.

  Next, the control unit 21 of the explainer terminal 20 executes a browsing page ratio display process (step S6-4). Specifically, the browsing status management unit of the control unit 21 calculates the browsing ratio of each slide page by dividing the number of viewers of each browsing page by the total number of listeners. Then, the browsing status management unit graphs the browsing status ratio for each slide page and outputs the graph to the touch panel 23.

  Next, the control unit 21 of the explainer terminal 20 executes a determination process as to whether there are many views other than the current page (step S6-5). Specifically, the browsing status management means of the control unit 21 specifies the current page displayed on the touch panel 23 of the explainer terminal 20. Next, the browsing status management means compares the browsing page having the highest browsing page ratio with the current page.

Here, when it is determined that there is much browsing other than the current page (in the case of “YES” in step S6-5), the control unit 21 of the explainer terminal 20 executes an alerting process (step S6-6). Specifically, the browsing status management means of the control unit 21 outputs a message on the touch panel 23 indicating that the listener is browsing a page other than the current page. Then, the process returns to step S6-1. On the other hand, when it is determined that there are many current browsing (in the case of “NO” in step S6-5), the control unit 21 of the explainer terminal 20 skips the alerting process (step S6-6), and step S6- Return to 1.
Thus, the presentation can be advanced according to the viewing status of the audience while confirming the viewing status of the audience.

  In the above embodiment, the control unit 11 of the listener terminal 10 executes the current page specifying process (step S3-2). In this case, the display control unit 113 may store the current page. When the “current page” button is selected on the touch panel 13, the display control unit 113 displays the current page of the slide material file 121 on the touch panel 13. Thereby, even when other slide pages are being browsed, it is possible to quickly return to the slide page.

In the above embodiment, the control unit 11 of the listener terminal 10 executes the current page display process (step S3-4). Here, the presenter may be able to set whether or not to force the audience to view the predetermined slide page. For this purpose, a force button used for forcing is displayed on the touch panel 23 of the presenter terminal 20. This page change control process will be described with reference to FIG.

Here, similarly to steps S2-1 and S2-2, the control unit 21 of the explainer terminal 20 executes a voice acquisition process (step S7-1) and a voice recognition process (step S7-2).
Next, the control part 21 of the instructor terminal 20 performs the determination process about whether it is forced (step S7-3). Specifically, the instruction conversion unit 214 of the control unit 21 determines whether or not the forced button displayed on the touch panel 23 has been pressed during the voice recognition process.

  When it determines with forced (in the case of "YES" in step S7-3), the control part 21 of the instructor terminal 20 performs a forced setting process (step S7-4). Specifically, the instruction conversion unit 214 of the control unit 21 sets a forced flag in a command transmitted to the listener terminal 10.

On the other hand, when it determines with it not being forced (in the case of "NO" in step S7-3), the control part 21 of the instructor terminal 20 skips a forced setting process (step S7-4).
And the control part 21 of the instructor terminal 20 performs a command transmission process (step S7-5). In this case, the current page information is included in the command.

  The controller 11 of the listener terminal 10 that has received the command from the explainer terminal 20 executes a command reception process in the same manner as in step S2-5 (step S7-6). Here, assuming that the application identifier is “slide”, the communication control unit 111 takes over the command to the display control unit 113 via the instruction control unit 112.

  Next, the control unit 11 of the listener terminal 10 performs a determination process as to whether or not it is compulsory (step S7-7). Specifically, the display control unit 113 of the control unit 11 determines whether the command received from the explainer terminal 20 includes a forced flag.

  If it is determined that the command is forced due to the inclusion of the forced flag in the command (in the case of “YES” in step S7-7), the control unit 11 of the listener terminal 10 executes a change process to the current page. (Step S7-10). Specifically, the display control means 113 of the control unit 11 changes to the current page specified on the explainer terminal 20.

  On the other hand, if it is determined that the command does not include a compulsory flag and is not compulsory (“NO” in step S7-7), the control unit 11 of the listener terminal 10 performs touch state detection processing. Execute (Step S7-8). Specifically, the display control unit 113 of the control unit 11 starts turning the page to the current page on the touch panel 13. Here, when the listener wishes to continue browsing the displayed slide page, he or she presses a part of the slide page with the finger on the touch panel 13. In this case, the display control unit 113 detects a touch situation on the touch panel 13.

  Next, the control unit 11 of the listener terminal 10 executes a determination process as to whether or not the page is fixed (step S7-9). Specifically, the display control unit 113 of the control unit 11 determines that the page is fixed in a touch state when the display unit 113 is pressed with a finger.

If it is determined that the page is fixed (“YES” in step S7-9), the process returns to the touch state detection process (step S7-8). In this case, the display control unit 113 stops the page change and continues displaying the slide page on the touch panel 13.

  On the other hand, when the finger is released in the touch state on the touch panel 13, the page fixing is released. When it is determined that the page is not fixed in this way (in the case of “NO” in step S7-9), the control unit 11 of the listener terminal 10 executes a process for confirming the change of the browsing page (step S7-9). Specifically, the display control unit 113 of the control unit 11 starts turning the page to the current page on the touch panel 13.

  Thereby, the presenter can force the audience to browse the predetermined slide page. Instead of the forced button, the forced setting process (step S7-4) may be executed when the keywords “attention” and “important” are detected in the voice recognition process.

  In the above embodiment, the control unit 21 of the presenter terminal 20 performs a speech recognition process (Step S2-2) and a command conversion process (Step S2-3). In this case, it is possible to change the command according to the current page of the slide material file. In this case, in the command table 223, a command corresponding to the text is recorded in association with the slide page. Thereby, various operations can be performed according to the slide page being displayed.

  In the above embodiment, the control unit 21 of the explainer terminal 20 executes command transmission processing (step S2-4). The command transmission method is not limited to this. For example, as shown in FIG. 11, the listener terminal 10 is provided with a plurality of layers, a command is transmitted from the explainer terminal 20 to the listener terminal 10 in the first layer, and the listener terminal 10 in the first layer The command may be transferred to the listener terminal 10 in the second hierarchy. In this case, the terminal identifier of the listener terminal 10 to which the command is transferred is stored in each listener terminal 10. Thereby, the burden of the command transmission process in the presenter terminal 20 can be reduced. In this case, redundancy is provided so that the listener terminals 10 in each hierarchy receive commands from a plurality of listener terminals 10 in the upper hierarchy. Thereby, even when a communication trouble occurs in some of the listener terminals 10, the command can be more reliably transferred to the listener terminals 10 in the lower hierarchy.

  -In the said embodiment, the control part 11 of the listener terminal 10 performs a display control process (step S2-6) and a speech synthesis output process (step S2-7). In this case, material display and audio output may be performed in a plurality of languages. In this case, slide material files (121, 221), related material files (122, 222), and audio files 123 in various languages are recorded in the data storage unit (12, 22). Then, language setting is performed in each listener terminal 10. In this case, the control unit 11 of the listener terminal 10 records the set language in the memory. Then, in the display control process (step S2-6) and the speech synthesis output process (step S2-7), a slide material file and an audio file corresponding to the language recorded in the memory are output. Thereby, a use language can be changed according to the user of the listener terminal 10.

  In the above embodiment, the same command is transmitted to all the listener terminals 10. In addition, a predetermined command may be transmitted only to the predetermined listener terminal 10. In this case, a list of the listener terminals 10 recorded in the terminal management file is displayed on the touch panel 23 of the explainer terminal 20. Then, a predetermined command is transmitted to the listener terminal 10 specified in the list. As this command, a command specified on the touch panel 23 or a command specified by voice recognition can be used.

  In the above embodiment, the command for changing the slide to the current page has been described. The command is not limited to this. For example, the opening / closing of the slide material file 121 may be controlled. In this case, when the voice “Open” is acquired together with the file name of the slide material file 121, a command for instructing a process of opening the slide material file 121 is generated. When the voice “Close” is acquired, a command for instructing a command for closing the opened slide material file 121 is generated.

  When a plurality of slide material files are used, the presenter terminal 20 identifies an active slide material file and transmits a command for changing the current page for this slide material. It may be.

  In the above embodiment, the slide material file 121 and the related material file 122 are stored in the data storage unit 12 of the listener terminal 10. In addition, a new file may be distributed to the listener terminal 10 during the presentation. For example, it is assumed that a new version of the slide material file 121 is distributed. In this case, the control unit 11 of the listener terminal 10 detects the open / closed state of the old version slide material file 121. If the old version slide material file 121 is closed, it is replaced with the new version slide material file 121. On the other hand, when the old version slide material file 121 is opened, the control unit 11 of the listener terminal 10 temporarily stores the distributed new version slide material file 121 in the memory. Then, when it is detected that the slide material file 121 is closed, the old version is replaced with the new version.
