  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram of a presentation support apparatus according to the first embodiment. In the first embodiment, the present page is calculated based on whether the current page of the material currently presented at the meeting has already been shown to the current participant, and the presenter is supported. Present information. As shown in FIG. 1, the presentation support apparatus according to the first embodiment includes a shared screen output unit 1, a presenter screen output unit 2, a page feed detection unit 3, a difference information generation unit 4, and a presentation information input unit 5. A presentation information recording unit 6 and an explanation level calculating unit 7.

  The present embodiment can be implemented as a program that causes a computer to function as a presentation support apparatus having the above components. In this case, the program according to the present embodiment is stored in a program storage device in the computer. The program storage device is composed of, for example, a nonvolatile semiconductor storage device or a magnetic disk device. The above program is read into a random access memory (RAM) under the control of a CPU (not shown) and executed by the CPU, whereby the computer can function as a presentation support apparatus. Note that an operating system that manages various computer resources and provides a graphical user interface (GUI) or the like is also installed in this computer.

  The shared screen output unit 1 generates and outputs a screen for presenting the contents of the presentation to a plurality of users. The screen output by the shared screen output unit 1 is presented to the participants participating in the presentation by being projected onto the screen by a projector device (not shown), for example.

  The presenter screen output unit 2 presents the content of the presentation and the support information generated by the explanation level calculation unit 7 to the user (presenter) who is executing the presentation. The presentation method and the presented user interface will be described in detail later.

  The page turning detection unit 3 detects the page turning from the user's page turning operation during the presentation, and measures the time taken to explain each page. As the page turning operation, for example, an input device such as a keyboard or a mouse (not shown) detects, for example, pressing of an Enter key or a cursor key, clicking of a mouse button, or the like.

  The difference information generation unit 4 detects which pages are copied and what corrections and corrections are made when a user creates a new material by reusing an existing presentation material. Difference information between the original material page and the newly created new material page is generated. The difference information generation method and the difference information format will be described in detail later.

  When the presentation information registration button is pressed from the presentation menu screen shown in FIG. 2, the presentation information input unit 5 displays a user interface as shown in FIG. 3, for example, and uses it for presentation as information related to the presentation performed by the user. The material and presentation attribute information are input and registered in the presentation information recording unit 6. Participant information is included in this attribute information.

  The presentation information recording unit 6 records material and attribute information input by the presentation information input unit 5, presentation progress information measured by the page turning detection unit 3, or difference information generated by the difference information generation unit 4. I do. An example of each recorded information is shown in FIGS. Details of each information will be described later.

  The explanation level calculation unit 7 calculates how much the page currently being explained during the presentation is to be explained, generates support information based on the page, and passes it to the presenter screen output unit 2. Calculation of the degree of explanation is based on whether the same / similar page has already been shown to the same participant based on the information recorded in the presentation information recording unit 6, in particular, the difference information with the participant information of the past presentation To calculate. The detailed calculation method will be described in detail later.

  Specific processing contents in the presentation support apparatus according to the first embodiment configured as described above will be described. FIG. 12 shows an outline of processing in the first embodiment.

  First, processing for registering materials used by a user in a presentation prior to a presentation in the apparatus will be described. FIG. 13 is a float chart showing the flow of registration of presentation materials.

  First, in step S1301, a menu screen is displayed. An example of the displayed menu is shown in FIG. In FIG. 2, when the [Presentation Information Registration] button is pressed, the process proceeds to a registration process and proceeds to Step S1302. In step S1302, a registration screen for registering presentation materials is displayed. An example of the displayed interface is shown in FIG.

  In step S1303, input waits until the user presses a button on the user interface. As shown in FIG. 3, the presentation name, the date and time when the presentation is performed, and the participants of the presentation are input as the attribute information of the presentation. In addition, the file name of the material used in the presentation is input.

  When the user presses a button on the user interface, the process proceeds to step S1304. It is determined whether the pressed button is a registration button. If No (ie, if the cancel button is pressed), the input information is discarded and the process is terminated.

  If Yes, the process advances to step S1305 to record the input information in the presentation information recording unit 6 and the process is terminated. An example of recorded information is shown in FIGS.

  FIG. 8 shows an example of presentation information recorded in the presentation information recording unit 6. As shown in FIG. 8, the presentation ID automatically assigned to identify each data, the input presentation name, the date and time, and the participants are recorded. In addition, a material ID that refers to the material corresponding to the material information that stores the registered material is recorded. FIG. 9 shows an example of material information recorded in the presentation information recording unit 6. As shown in FIG. 9, the material ID automatically assigned to identify each data, the file name of the input material, and the data of the file body are recorded as binary data.

  Next, a description will be given of a process for measuring the time taken for the presentation of each page of the material when the presentation is performed using the presentation material registered by the user. FIG. 14 is a float chart showing the flow of processing during presentation execution.

First, in step S1401, a menu screen is displayed. An example of the displayed menu is shown in FIG. In FIG. 2, when the “presentation execution” button is pressed, the process proceeds to an execution process, and the process proceeds to step S1402.

  In step S1402, a list of presentations registered is displayed, and a selection screen for allowing the user to select which presentation to execute is displayed. An example of the selection screen is shown in FIG. As shown in FIG. 4, the presentation name and date and time are displayed as registered presentation information. The user selects a presentation to be executed from a list of registered presentations. By comparing the current date and time with the scheduled execution date and time of the registered presentation, the corresponding presentation information may be automatically selected. After selecting, press the “execute” button to move to the next step.

  In step S1403, a timer built in the page feed detection unit 3 is initialized, and time measurement is started.

  In step S1404, the current page is output to the shared screen output unit 1 and the presenter screen output unit 2. The screens output to both output units are basically the same, but if the support information is presented by the explanation level calculation unit 7, the screens may be different. Details will be described later.

  In step S1405, the process waits until the user performs a page turning operation. When a page turning operation is detected by the page turning detection unit 3, the process proceeds to the next step.

  In step S1406, the page number of the previous page and the time measured by the timer are recorded in the presentation information recording unit 6. An example of the recorded progress information is shown in FIG. As shown in the figure, a target presentation ID that refers to information of a presentation that is currently being executed, a page number, and a time taken to explain the page are recorded.

  In step S1407, it is determined whether the last page has been completed, that is, whether the presentation has been completed. If the determination is No, that is, there are pages to be announced, the process returns to step S1403 and continues. If the determination is Yes, the process ends.

  Next, a flow of processing for creating a new material by reusing an already registered material and generating difference information between the material of the reuse source and the newly created material will be described. FIG. 15 is a float chart showing the flow of processing for creating a new material by reuse.

  First, in step S1501, a menu screen is displayed. An example of the displayed menu is shown in FIG. In FIG. 2, when the “view presentation information” button is pressed, the process proceeds to step S1502.

  In step S1502, a list of presentation information currently registered is displayed. An example of the displayed screen is shown in FIG. As shown in the figure, the presentation name and date and time are displayed as registered presentation information. The user selects a presentation for which detailed information is to be viewed and presses a “detailed browsing” button to move to the next step.

  A screen for displaying detailed information regarding the presentation selected in step S1503 is displayed. FIG. 6 shows an example of a detailed information display screen. As shown in the figure, the presentation name, date and time, participants, and the file name of the used material are displayed as the detailed information of the presentation.

  In step S1504, it is determined whether the “reuse” button has been pressed. If the determination is No, that is, if the “cancel” button is pressed, the process returns to step S1502 and the list screen is displayed again. If the determination is yes, go to the next step.

  A screen for selecting a page to be reused in the material selected in step S1505 is displayed. FIG. 7 shows an example of the page selection screen. As shown in the figure, each page of the selected material is displayed as a thumbnail, and the user selects a page to be reused using an input device such as a mouse. Multiple pages can be selected for pages to be reused.

  In step S1506, it is determined whether the “New” button has been pressed on the page selection screen. If the determination is No, that is, if the “cancel” button is pressed, the process returns to step S1502 and the list screen is displayed again. If the determination is yes, go to the next step.

  In step S1507, the page selected on the page selection screen is duplicated to create a new material file, and a corresponding external application is started to edit the material. The user operates the started external application to correct the duplicated page or add a new page to complete a new document. When the user completes the material, saves the file, and terminates the external application, the process proceeds to the next step.

  In step S1508, the information of the newly created material is stored in the presentation information recording unit 6 with respect to the material ID, file name, and data as shown in FIG.

  In step S1509, the difference information generation unit 4 compares the reuse source page with the page created by copying / modifying the page, generates the difference information, and sends it to the presentation information recording unit 6. Store. An example of the recorded difference information is shown in FIG. An outline of the difference information generation method is shown in FIG. As illustrated in FIG. 16, a page that is reused and a page created based on the page are regarded as images, and a newly added / deleted region is detected by detecting a difference between the two images. A rectangle including the detected area is calculated, and the x / y coordinate and the width w / height h of the rectangle are stored as difference information in the presentation information recording unit 6 as shown in FIG. When there is no difference at all, that is, when the page is simply duplicated, the data of the difference rectangle portion is empty. When the difference information is generated and stored, the process ends.

  Next, a description will be given of the flow of processing for calculating the degree of explanation of the page during the presentation using the material created by reuse and presenting the support information based on the calculation.

  First, the presentation of the material created by reuse is registered as described above with reference to FIG. Also, the registered presentation is executed as described above with reference to FIG. However, in the case of presentation of materials created by reuse here, a flow for presenting support information is executed instead of steps S1403 and S1404 in FIG. A flow chart of the process of presenting support information is shown in FIG.

  Following step S1403 in FIG. 14, step S1701 is executed. In step S1701, it is determined whether the current page of the material being used in the presentation is a page created by reusing a page of another material. Specifically, if there is data that matches the new material ID and the new material page in which the current material ID and the current page number are the difference information (FIG. 11) in the presentation information storage unit, the current page is determined as a reuse page. . If the determination is No, the process proceeds to step S1704. If the determination is Yes, the process proceeds to step S1702.

  In step S1702, it is determined whether the current page reuse source page has already been presented to the current participant. Specifically, in the previous step, the original material ID is extracted from the difference information, the data that used the material is extracted from the presentation information (Fig. 8), the participants in the presentation that used the material and the participation in the current presentation It is determined whether the participants match, that is, whether all the current participants are included in the past participants. Here, the past participant information refers to the participant information of FIG. If the determination is No, the process proceeds to step S1704. On the other hand, if the determination is yes, the process proceeds to step S1703.

  In step S1703, it is determined whether there is difference information between the current page and the reuse source page. Specifically, it is determined whether there is data in the difference rectangle in the difference information extracted in step S1701. If the determination is yes, the process proceeds to step S1705, and if the determination is no, the process proceeds to step S1706.

  In step S1704, the current page is not a reuse page, or is a reuse page, but the current participant has never presented a reuse source page, so the current page should be explained normally. Set the degree to Normal.

  In step S1705, the reuse source page of the current page has been presented to the current participant, but since a difference is included, only the difference portion should be explained, so the degree of explanation is set to Low.

  In step S1706, the page that is exactly the same as the current page has been presented to the current participant, so that the explanation of the page can be skipped, and the degree of explanation is set to Skip.

  In step S1707, the support information is displayed together with the document page according to the calculated degree of explanation. Details of the display will be described later with reference to FIGS. 18, 19, and 20.

  This completes the explanation-level calculation process, and step S1405 in FIG. 14 is executed following step S1707.

  Next, a screen display example displayed on the shared screen and the presenter screen in step S1707 of the float chart in FIG. 17 will be described.

  FIG. 18 shows an example in which materials and support information are output on the presenter screen according to the calculated degree of explanation. As shown in FIG. 5A, the presenter screen is composed of a material display area for displaying the current page of the material and a support information display area for displaying support information corresponding to the degree of explanation. As for the page whose degree of explanation is determined to be Normal, only the current page is displayed in the material display area as shown in FIG. In order to explain the difference part for the page whose explanation level is determined to be Low, the document display part highlights and highlights the difference rectangle part as shown in (b) in the figure, and only the difference part is provided as support information. Is displayed, and as a reason for this, a message is displayed to the current participant that other than the difference portion has already been explained. Also, the date and time at that time may be displayed to indicate when the presentation (conference) was explained. A page whose explanation level is determined to be Skip is displayed in the material display section darkly as shown in (c) in the figure, and a message that the explanation is omitted because the current page has already been explained to the participant as support information. Also, the date and time at that time may be displayed to indicate when the presentation (conference) was explained.

  FIG. 19 shows a display example on the shared screen. In the shared screen, basically, the current page is displayed in its original state as shown in FIG. 5A, and the support information is displayed only to the presenter. However, in the case of a page that contains difference information, for example, as in the example in Fig. 7 (b), the difference rectangle is highlighted so that the participant can understand which part is the difference. In this state, the page may be displayed on the full screen.

  In addition, in the float chart FIG. 17, it is determined only whether the current page has been presented to the previous participant of the current presentation. For example, it is determined whether or not the current page has been presented to some people. For example, as shown in the example of FIG. 20, it is possible to display who is shown as support information and who is not shown.

  According to the first embodiment described above, by accumulating information on the presentation performed by the user, and by accumulating difference information when the user creates a new material by reusing the existing material, While the user is performing a presentation, support information is presented based on whether the current page is a reusable slide, whether it has already been explained to the current participant, and whether the current page contains differential information. Therefore, the user can execute an efficient presentation based on the information.

  In the first embodiment, participant information is manually input as presentation attribute information. For example, a wireless tag held by each participant is automatically read by a tag reader installed in the conference room. Participant information may be acquired. In addition, it has been described that the creation of a new material by executing a presentation or reusing an existing material is performed on the screen shown in FIGS. 2 to 7, but it is directly performed on a general file management application on the operating system. The corresponding application may be activated by performing an operation. At this time, the difference information may be created based on a user operation on the application, for example, file copy, page copy, character input, figure insertion, or the like.

  FIG. 21 is a block diagram of a presentation support apparatus according to the second embodiment. In the second embodiment, the presentation level of the current page is calculated based on the amount of questions and answers and the presentation time when presenting the same material in the past at conference presentations and lecture presentations. Make a presentation. In the presentation support device according to the present embodiment, a voice input unit 8, a question and answer extraction unit 9, and an additional explanation candidate extraction unit 10 are added to the presentation support device according to the first embodiment described above.

  Except for the additional functions of the voice input unit 8, the question and answer extraction unit 9, the additional explanation candidate extraction unit 10, and the explanation degree calculation unit 7, they are the same as those in the first embodiment. In FIG. 21, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  The voice input unit (conversion unit) 8 inputs a voice during a question-and-answer session in a presentation using, for example, a microphone, recognizes the input voice, and converts it into text.

  The question and answer extraction unit 9 extracts the question part from the participant and the response part of the presenter corresponding to the question part from the text converted by the voice input unit 8. As an extraction method, for example, a sentence end expression used in a typical question sentence, for example, "...?", "... What do you think?", "Please explain ..." A sentence in which the expression is used is defined in advance, and the sentence is searched and regarded as a question part. Extraction is performed by regarding a sentence that continues to the extracted question part as a response part. The extracted question and answer information is recorded in the presentation information recording unit 6. An example of recorded information is shown in FIG. Details will be described later.

  The additional explanation candidate extraction unit 10 extracts items to be added to the currently explained page during the presentation, generates support information based on the items, and passes them to the presenter screen output unit 2. The extraction method extracts information that has been questioned about the page in the past based on information recorded in the presentation information recording unit 6, particularly progress information and question-and-answer information, and presents it as support information. Details will be described later.

  In addition to the function in the first embodiment, the explanation degree calculation unit 7 has a function of calculating the degree of explanation based on the question and answer information recorded in the presentation information record in the second embodiment. The calculation method will be described in detail later.

  Specific processing contents in the presentation support apparatus according to the second embodiment configured as described above will be described. FIG. 23 shows an outline of processing in the second embodiment.

  Since the flow of registering presentation materials is the same as that in the first embodiment, description thereof is omitted. However, regarding the participant information when registering the material, the participant part shall be registered as blank in a presentation in which a large number of unspecified participants such as academic societies and lectures participate.

  Similarly, the flow of the presentation execution is the same as that in the first embodiment, and a description thereof will be omitted.

  Next, the process of extracting the question and answer portion from the voice and recording the information at the question and answer time after the presentation ends will be described. FIG. 24 is a float chart showing the flow of processing for generating question and answer information.

  In step S2401, voices in question and response from the presenter are input, and voice recognition is performed to convert the voice into text.

  In step S2402, a question part and a response part are extracted from the converted text.

  Step S2403 is executed in parallel with steps S2401 and S2402, and the page designated by the presenter selecting the corresponding material page according to the questions from the participants is displayed on the shared screen.

  In step S2404, the question and answer information is recorded in the presentation recording unit. As shown in FIG. 22, the recorded information includes a presentation ID that refers to information on a presentation that is currently being executed, a page number designated and displayed by the presenter, and extracted questions and responses.

  In step S2405, it is determined whether the question and answer time has ended. If No, the process returns to the beginning of the flow and the process is repeated. If the determination is Yes, the process ends.

  Next, a description will be given of the flow of processing for calculating the degree of explanation of a page and presenting support information based on the calculation of the degree of explanation of the page in a scene where the same material is presented in another place.

  First, a presentation using the same material is registered as described with reference to FIG. 13 in the description of the first embodiment. Also, the registered presentation is executed as described above with reference to FIG. However, in the case of a presentation using the same material here, a flow for presenting support information is executed instead of steps S1403 and S1404 in FIG. The flow of the process of presenting support information is shown in the float chart FIG.

  First, in step S2501, the presentation information data that first used the material used in the presentation that is currently being executed is extracted from the information recording section, and the progress information that refers to the presentation ID is used for the presentation after the current page. The actual measurement time is calculated and substituted into the variable T.

  In step S2502, the remaining time of the current presentation is substituted into variable t.

  In step S2503, it is determined whether the remaining time t is equal to or greater than the actual measurement time T, that is, whether the remaining time is actually larger than the time taken for the explanation after the current page and there is a time margin. If the determination is Yes, that is, if there is time, the process proceeds to step S2504. If the determination is No, that is, if there is no time margin, the process proceeds to step S2505.

  In step S2504, it is determined whether the question and answer information for the current page exists in the information recording unit. That is, it is determined whether there has been a question and answer for the current page in past presentations performed using the same material. Specifically, data that refers to the document ID corresponding to the current document is extracted from the presentation information, data that refers to the presentation ID of the extracted presentation information is calculated from the question and answer information, and the current data is included in the calculated data. Determine whether the page is included. If the determination is No, the process proceeds to step S2506, and if the determination is Yes, the process proceeds to step S2507.

  In step S2505, the explanation level is set to Low because there is not enough time to explain the remaining pages as usual.

  In step S2506, although there is time for presentation, there has been no question about the current page so far, so that the explanation can be given as usual, and the degree of explanation is set to Normal.

  In step S2507, since there is time for the presentation and there has been a question about the current page, the explanation level is set to High so that additional explanation should be given.

  In step S2508, as a matter to be described in the additional explanation, a question and answer so far for the page is extracted from the presentation recording unit.

  In step S2509, the support information is displayed together with the document page according to the calculated degree of explanation. Details of the display will be described later in detail with reference to FIG.

  This completes the explanation-level calculation process, and step S1405 in FIG. 14 is executed following step S2509.

Next, a screen display example displayed on the presenter screen in step S2509 of the float chart in FIG. 25 will be described.

  FIG. 26 shows an example in which materials and support information are output on the presenter screen according to the calculated degree of explanation. As shown in (a) and (c) of the figure, the presenter screen has a material display area that displays the current page of the material, a support information display area that displays support information according to the degree of explanation, and an additional explanation. It is composed of an additional explanation candidate display section that displays candidate items to be displayed. As for the page whose degree of explanation is determined to be Normal, only the current page is displayed in the material display area as shown in FIG. For pages for which the degree of explanation is determined to be Low, as shown in (b) in the figure, since the time has been reduced, the fact that explanation is given earlier than usual is displayed as support information. As for the page whose degree of explanation was judged as High, there was a question about the page in the previous presentations, so in order to add explanation about it as well, as shown in FIG. The fact that the explanation for the question is sufficiently performed is displayed as support information, and the additional explanation candidate display unit displays the contents of the question so far. By referring to this question, the presenter can grasp the matters to be added and explained.

  According to the second embodiment of the present invention described above, whether or not there was a question about the current page by accumulating the questions and answers when the same material was presented in the past in a conference presentation or lecture presentation, The support information is presented based on whether or not the presentation time is available, and candidates to be additionally explained are presented, so that the user can perform an efficient presentation based on the information.
