Description

  The present invention relates to a presentation apparatus, a presentation method, and a program for presenting information useful for supporting the progress of a presentation (presentation).

  Personal computers (PCs) have come to be used for all presentations, such as in-house meetings and meetings, proposal plans for external customers, explanation of new products, and research presentations at academic conferences. Electronic materials used for presentations are divided in some display units such as pages and slides, and stored in advance in a storage device of a PC. The PC operated by the presenter reads out the data of these materials and presents it to the audience through a video output device such as a projector.

  In a remote conference or the like using a computer network, presentation materials are presented on the terminals of each audience (participant of the conference). The information displayed on the presenter terminal and the information displayed on the audience terminal are not necessarily the same. For example, in many presentation software, an explanatory manuscript can be displayed on the presenter terminal together with materials for the audience. There are many practical systems that support the entire presentation by presenting supplementary information at the presenter terminal as well as presenting electronic materials using the audience terminal.

  The quality of presentation depends largely on the skill and proficiency of the presenter, and it is not easy to acquire sufficient skills for effective presentation. What is considered particularly important in the presentation is to provide content (content) based on the level of knowledge and interest of the audience at a density that satisfies the audience. For this reason, presenters must be able to detect whether the audience is seeking more detailed explanations about the content or whether they want more questions and answers. In addition, the content and progress of the presentation must be changed flexibly to deal with such situations. Whether or not you can do these things is particularly likely to vary depending on the skills of the presenter.

  In order to deal with the above problems, a mechanism has been proposed in which each audience member marks an interesting place during a presentation, or a sentence written as a question is conveyed from the audience to the presenter. While listening to the presentation, the audience can access and mark the presentation material provided through the server on the presenter's side from their PC. The presenter can see during the presentation what part of the material has been marked by how much audience.

  There is also known a technique for determining and presenting whether or not the explanation speed is appropriate by obtaining the difference between the location in the material being browsed by the audience and the location in the material being explained by the presenter. It is also possible to count the part that the audience has marked and to show during the presentation which part the audience is interested in.

  Patent Document 1 describes a mechanism for detecting a degree of interest of an audience and advancing a presentation while selecting any appropriate one from a plurality of presentation progress patterns prepared in advance.

  Patent Document 2 describes a mechanism for presenting guide information in accordance with audience expertise. The guide information is presented to the presenter so that the explanation of the content highly similar to the specialty will be brief and the content not so will be explained in detail.

Patent Document 3 describes a mechanism by which an audience can send questions related to presentation materials to a presenter. The presenter can grasp how many questions are coming to which part during the presentation. Thus, presenters can preferentially answer questions that are of high importance or that are of interest to many audiences.

  In the above-described conventional technique, for example, it is possible to estimate how many people are interested in which part of the presentation material and immediately present it to the presenter. However, even if it turns out that this material should be explained in detail, the presentation will not be effective as a whole if the explanation is not made after the explanation of the previous material.

  Many presenters become fully engaged just in preparation and practice once the presentation has started, and even if they know what part of the presentation content they are interested in, It is very difficult to reflect information in ongoing announcements. Also, simply presenting audience response information can confuse presenters, which can lead to bad results.

  Therefore, it is desirable to provide a mechanism for supporting the progress of the presentation by sequentially acquiring the interest information of the audience and presenting in advance to the presenter the places that should be explained mainly.

  A presentation device according to an aspect of the present invention includes a first presentation unit that presents presentation material having a plurality of display units, a providing unit that provides the presentation material to an audience terminal, and the presentation material is in the audience terminal An acquisition unit that acquires context information representing an action of the audience when presented; a first analysis unit that calculates an interest level of each of the plurality of display units by analyzing the context information; and the presentation material And a second analysis unit for obtaining another display unit related to the character string of interest, and for the other display unit. A generation unit for generating progress support information indicating how to display the other display units according to the importance, and assigning importance corresponding to the degree of interest Comprising a second presentation portion for presenting the line support information along with the other display units, the.

  According to the present invention, a presentation device that acquires the interest information of the audience along with the progress of the presentation and supports the progress of the presentation by previously presenting to the presenter a location related to the location that should be explained mainly, Presentation methods and programs can be provided.

  One embodiment of a presentation support system for supporting a presentation using an information device is shown in FIG. Audience interest information for the material being presented is sequentially acquired at the audience terminal 108. This interest information is fed back to the context information acquisition unit 109 of the presenter terminal that can be viewed by the presenter.

  The presenter records the presentation material in advance in the presentation material recording unit 103. When the presenter starts the presentation, the presenter inputs a display unit (page) instruction to be displayed using the presentation material display command input unit 101. It is assumed that the announcement material command input unit 101 can input instructions of at least “display next page”, “display previous page”, and “display specific page”. When the presentation material acquisition unit 102 receives an instruction input from the presentation material command input unit 101, the presentation material acquisition unit 102 acquires the corresponding presentation material page from the presentation material recording unit 103 and causes the presentation material presentation unit 104 to display the page. The presentation material presentation unit 104 corresponds to a display device for an audience, such as a large screen projector. For the presenter, not only the presentation material but also the progress support information acquired by the progress support information acquisition unit 105 is presented together with the presentation material. This information presentation is performed by the progress support information presentation unit 106. The progress support information presentation unit 106 performs various processes on the display contents so that the presenter can easily recognize the progress support information according to the contents of the progress support information.

  The presentation material providing unit 107 provides the audience terminal 108 with information on a page that is currently being presented, a page that has already been displayed, or a page that will be announced in the future. In this embodiment, it is assumed that the audience terminal 108 is connected mainly by a network such as TCP / IP.

  The context information acquisition unit 109 can specify presentation material presentation information of the presenter, communication record between the audience terminal 108 and the presentation material providing unit 107, information that can specify operations performed on the audience terminal 108, that is, context information. To collect. As information specifying the operation performed on the audience terminal 108, for example, who (name, knowledge level (beginner or expert), position (president or VIP or general audience)) acquires which page , How many seconds it is viewed, how many times it is viewed, and what other pages are viewed. If a characterization operation is performed by marking a line or a circle, it indicates what characterization operation was performed on which part in the presentation material.

  As a configuration for collecting context information, a configuration in which the audience terminal 108 sequentially sends operation information, a presentation material providing unit 107 is provided with a browsing function and a characterization function, and an operation of the audience at the audience terminal 108 is presented by a presentation material providing unit. A configuration may be considered in which the information 107 is sent to the context information acquisition unit 109 sequentially (for example, at regular intervals). Particularly in the latter case, in the case of a web-based system example, the presentation material providing unit 107 takes the form of a web application that can view the presentation material, and the audience terminal 108 is merely a web browser.

  The “context information” is information regarding the situation where the place of presentation is placed. Specifically, information representing a history of actions indicating what the presenter or audience has operated by operating the presenter terminal or audience terminal 108 and what has been seen in the presentation material is defined as context information. Therefore, the context information is specifically composed of a set of action records of presenters and audiences.

  The context information is recorded by the context information recording unit 110. Based on the context information, the portion-of-interest analysis unit 111 indicates how much the audience is interested in each display unit among the information specifically included in the presentation material (hereinafter referred to as “degree of interest”). To analyze the information of interest. The progress support information generation unit 112 keeps the description of which part of the pages after the present short from the content of the part of interest information and the relationship information of each part in the presentation material provided by the presentation material structure analysis unit 113. Instead, it generates progress support information that indicates which part should be described in detail, and where it is particularly detailed or where a short description may be omitted, and sends it to the progress support information acquisition unit 105.

  FIG. 2 is a diagram illustrating an example of the presentation material recording table 201 recorded by the presentation material recording unit 103. The presentation material record table 201 records information related to at least one presentation material, and is composed of presentation material information 202, a display unit 203, a scheduled time 204, a title 205, and contents 206.

  The presentation material information 202 records the identification information of the presentation material and the time required for the presentation. Typical identification information is the file name of the presentation material. The required time is the total scheduled time or the presentation time given to the presenter. The display unit 203 is index information that can be specified when the presenter displays this presentation material. Typically, it is the page number of the presentation material.

  The estimated required time 204 is a time estimated to be necessary for explaining the display unit. The typical scheduled time is the time required for the presentation practice performed in advance, or simply the presentation time given to the presenter divided by the number of display units. The title 205 is the title of the display unit and is recorded as text information.

  The content 206 is the display content of the display unit. In this example, only text information is shown, but in many cases, text information accompanied with layout information, animation, audio information for reproduction, and moving image information are included. In the present embodiment, it is necessary to handle text information at a minimum. Further, the display content generally has a hierarchical structure such as a large heading, a medium heading, and a small heading. In the present embodiment, a line starting with “■” is a major heading of the page, a line starting with “◯” is a heading in the page, and a line starting with “·” is a subheading of the page. When the presentation material information is acquired from the presentation material recording unit 103, it is assumed that rule information for discriminating whether the information of these headings is given or not is given to the acquisition side. That is, the acquisition side can distinguish which part is which heading.

  FIG. 3 is a diagram illustrating an example of a data structure of context information recorded by the context information recording unit 110. The user attribute table 301 is an example of a table that describes the position of each audience with respect to the presentation contents, and includes a user ID 302, a role 303, and a knowledge level 304.

  The user ID 302 is an ID for identifying an individual audience. This corresponds to the ID of the audience terminal 108, the participation registration number at the presentation or seminar, and the like. The role 303 and the knowledge level 304 are information indicating the position of the user regarding the presentation. When this information is set, the context information can be classified and handled for each of these attributes. The user ID 302, the role 303, and the knowledge level 304 are directly registered by the audience, or registered by the presenter using past participation information and publicly available information.

  The context information recording table 305 is an example of a table that records presentation material presentation information of the presenter and contents of actions from the audience with respect to the presentation material. The occurrence time 306, user ID 307, operation 308, display unit 309, characterization Consists of objects 310. The occurrence time 306 and the user ID 307 are the time when this entry occurred and the target user. An operation 308 represents an action type. There are at least two actions of “page presentation” and “acquire page”, and preferably an action of “characterizing” is added. A display unit 309 is a display unit to be operated. The characterizing object 310 describes the contents of the characterization when the operation 308 is “characterizing”. For example, the entry 311 describes the information that the user Present_D has underlined the text “company-specific property” on the third page at the time 4 minutes and 1 second after the start of the presentation. Is.

FIG. 4 is a time chart showing examples of actions from a presenter and a typical audience. The information shown in this time chart is actually recorded in the context information recording table 305. However, it should be noted that the example shown in FIG. 4 does not partially match the example of FIG. 3 used to describe the context information recording table 305.
According to FIG. 4, the required time 401 for each scheduled page, the presenter 402, the general person 403 who takes time to understand the contents of the explanation (they tend to follow the presentation material later, and sometimes explain the material already explained). Review 404) Expert 404 who knows the basic contents and wants to grasp only important points (proceeds at a faster pace than the announcement), and basically annotating only the part of interest after the announcement VIP405 You can see an example of the behavior of one presenter and three audiences who take typical actions: (Proceed on the same page as the presentation).

  Here, an explanation will be given by taking as an example the time point when the elapsed time from the start of presentation is 9 minutes and the user is about to enter the sixth page of the explanatory material.

  The scheduled required time 401 corresponds to information recorded in the presentation material storage unit 103 (scheduled time 204). According to the chart of FIG. 4, it can be seen that the presenter 402 took the extra time for about 30 seconds on the 4th page, and omitted the explanation on the 5th page and instead adjusted the bottom of the book.

  A general user (General_User_A) 403 spent a lot of time explaining the third page, viewed the information on the fourth page in half time, moved to the fifth page with the announcement, but still cannot understand Therefore, it turns out that it is in the state which is returning to the 4th page and confirming the contents. The expert user (Expert_User_C) 404 has read the material at his own pace from the start of the presentation, and after checking the contents for the first time on the 6th page, read the 7th page carefully, and immediately after moving to the 8th page I understand that. The VIP user (Present_D) 405 characterizes the “company-specific properties” on the third page while viewing the material at the same timing as the presenter, and begins browsing the fifth page at a timing slightly earlier than the presenter. I understand that.

  FIG. 5 is a flowchart showing the processing contents of the part-of-interest analysis unit 111. The part-of-interest analysis unit 111 checks the content of the context information recording unit 110 at regular time intervals, and starts analysis processing when the content has changed. Alternatively, the context information recording unit 110 may be provided with a mechanism generally called an event-driven type, that is, a mechanism that prompts the interested part analysis unit 111 to perform an operation when some information is written in the context information recording unit 110. In any case, in this embodiment, the part-of-interest analysis unit 111 performs an analysis process whenever there is a change in context information.

  When the part-of-interest analysis unit 111 starts the analysis processing, three items of presentation material information 201, context information 305, and target time are passed as input information (step 501). Although the target time can be omitted, in this case, all context information that can be acquired at the start of the processing is set as the processing target.

  The simplest method of analyzing the part of interest is for each display unit, which audience refers to that display unit over how long and how many times (if any part is characterized, where is the string Or the like, and the degree of interest of each audience for each display unit is output as a vector expression (steps 502 to 507).

  For example, the user (general person) 403 shown in FIG. 4 browses the display unit 4 for about 2 minutes and 20 seconds, and the number of times of browsing is two. It is not characterized. The case where the total interest level for this page is expressed by a scalar value will be described.

  The part-of-interest analysis unit 111 calculates, for example, a degree of interest derived from browsing time as ((browsing time−scheduled required time) / scheduled required time), a degree of interest derived from the number of browsing times (2-3 times: +1 point, 3 More than once: a value such as +2 points), a value calculated by a predetermined function, and a degree of interest derived from characterization (underline: +1 point, wavy line: +2 points, box drawing that covers the whole heading: a value such as +3 points) The total value calculated by a predetermined function is used.

In the above example, the estimated required time is used. However, when information indicating the time actually used by the presenter can be acquired, the time information may be calculated instead of the estimated required time. For users who switch display units according to the presenter's pace, more accurate context information can be obtained by this method.
The portion-of-interest analysis unit 111 uses the value of the degree of interest calculated as described above, and includes four attributes (user information, display unit, degree of interest, and portion that can be determined that the user is most interested). Generate an interest vector.

A portion (interesting portion) that can be determined to have the most interest is the target character string if it has been characterized. Although not characterized, if the degree of interest is high in view of the viewing time or the number of times of viewing, the page itself is set as the “interested portion”. Hereinafter, this is sometimes simply referred to as “topic”. According to the above processing, the interest level vector generated by the interested portion analysis unit 111 from the context information 403 of the general person (General_User_A) is
(General_User_A, display unit 1, +0.0, none),
(General_User_A, display unit 2, +0.0, none),
(General_User_A, display unit 3, +0.2 (viewing time), entire page),
(General_User_A, display unit 4, +1.0 (view count), entire page),
(General_User_A, display unit 5, -0.5 (viewing time), entire page)
It becomes a variation. Similarly, the interest level vectors of the experts 404 and VIP 405 are as follows.

(Expert_User_C, display unit 1, -0.5 (viewing time), none),
(Expert_User_C, display unit 2, -0.5 (viewing time), none),
(Expert_User_C, display unit 3, -0.5 (viewing time), entire page),
(Expert_User_C, display unit 4, -0.5 (viewing time), entire page),
(Expert_User_C, display unit 5, -0.7 (viewing time), entire page),
(Expert_User_C, display unit 6, -0.3 (viewing time), entire page),
(Expert_User_C, display unit 7, +0.3 (viewing time), entire page),
(Expert_User_C, display unit 1, -0.5 (viewing time), none),
(Expert_User_C, display unit 2, -0.5 (viewing time), none),
(President_D, display unit 1, +0.0, none),
(President_D, display unit 2, +0.0, none),
(President_D, display unit 3, +0.3 (browsing time) +2 (characteristic: wavy line), “proprietary property”),
(Present_D, display unit 4, +0.0, none)
There are several variations of the interest level calculation method, such as ignoring pages that have very little browsing time simply as meaning movement, and setting an upper threshold for losing consciousness if they are extremely long. It is done. In addition, regarding the topic, in an environment in which the presenter's pointing information and the description time for each headline can be acquired as context information, it may be possible to specify a topic that is interested in, for example, in the headline unit instead of the entire page.

  FIG. 6 is a flowchart showing the processing contents of the presentation material structure analysis unit 113. The presentation material structure analysis unit 113 analyzes the relationship between the display units or the headings of the presentation material, and extracts another part that is structurally related to the part when the degree of interest of the part is high.

  The presentation material information 201 and the interest level vector information (generated at step 506) are passed as input information when the presentation material structure analysis unit 113 starts operating (step 601). Based on these pieces of information, processing is sequentially performed for each interest level vector of each display unit (steps 602 and 603).

  First, using a topic attribute of the interest level vector (characterized character string, part or all of a page, etc.), it is determined what character string is specifically interested (step 604). Such a character string is called an interest character string. If there is a character string that is characterized, the character string itself is set as a character string of interest (step 605). When the topic attribute is the entire page or a part thereof, a characteristic character string is obtained from the title and each heading of the page, and these are used as the interest character string. Here, the “characteristic” character string is, for example, a character string with a small number of appearances across all pages. There are a method for obtaining by a perfect match and a method for obtaining by dividing into morphemes and that the number of appearances of each morpheme is less than a certain number.

  For example, consider obtaining a character string of interest for display unit 7 (see FIG. 2 and the like). When the “bidirectional link”, which is the middle heading, is divided into morphemes, it is divided into “bidirectional (general noun)” + “link (variable connection noun)”. In all the presentation materials, there are 2 places where “Bidirectional” is included and 3 places where “Link” is included. Therefore, the “bidirectional link” has a sufficiently small number of appearances compared to other “users” and “tags”, and can be said to be a character string characteristic of this page.

  In the display unit 7, the “data structure”, which is a large heading, has the same characteristics, but the medium heading over the large heading and the subheading over the medium heading give the features with finer granularity in content. Can be caught. For such creation, various algorithm variations and fine tuning methods can be considered depending on the production of the presentation material. Here, as a simple example, a method in which all of the big heading, middle heading, and small heading are candidates for the character string of interest is given (step 606).

When the character string of interest is determined, a title or heading including the character string of interest is searched for including other display units. A structural relationship is determined for the found character string in the order of display units (step 607). For example, when the display unit including “bidirectional link” is in the subheadings of page 5 and page 8, the structural relationship is
Page 5: Subheading (“bidirectional link”) → Page 7: Middle heading (“bidirectional link”) → Page 8: Subheading (“bidirectional link”)
It becomes. When multiple character strings of interest appear on the same page, the relationship is defined in the order of appearance.

  FIG. 7 illustrates the processing result of the presentation material structure analysis unit 113. The presentation material information will be described using display units 3 (701) to 8 (707).

  The interest level vectors used in the description are three (X (708), Y (709), and Z (710)). X (708) belongs to the user Present_D, and indicates that the display unit 3 is interested in the “company-specific property” (the wavy line is drawn). Y (709) and Z (710) are those of user Expert_User_C. Y (709) indicates that the display unit 4 has advanced in a very short time, that is, it is sparse, and Z (710) indicates that it has taken time with respect to the display unit 7, that is, it is interested. Yes. However, Expert_User_C does not characterize materials.

  First, obtaining a structural relationship using the interest degree vector X will be described. The topic of the interest vector X is “company-specific properties”, and the similar parts to this word are the title (712) and main heading (713) of page 4, the main heading (714) of page 6, and the page 9 Seen in the heading (715). “Similar” may be an exact match or may be the same if the distance is short, using a scale generally known as the edit distance. For example, “company-specific property” and “company property” are editing distance 2 and “company-specific property” is editing distance 1. When these are determined in the page order and the order of appearance, they are expressed as 711 → 712 → 713 → 714 → 715.

  Next, the structural relationship is obtained using the interest level vector Y. Although the topic of the interest level vector Y is none (the whole page), the interest character string of the page 4 is calculated, and the explanation will be made assuming that it becomes “company-specific property”. The parts similar to the character string of interest are the title (712), the main heading (713), the heading in page 6 (714), and the heading in page 9 (715). When it is determined, 712 → 713 → 714 → 715.

  Next, the structural relationship is obtained using the interest level vector Z (710). Although the topic of the interest level vector Z is the entire page, the interest character string of the page 7 is calculated, and the explanation will be made assuming that there are two “Web-Service API” (716) and “Bidirectional link” (717). . For the “Web-Service API”, the portion similar to the character string of interest is the heading in page 7 (716) → the page 9 subheading (720), and the “bidirectional link” is the page 5 subheading (718). → heading in page 7 (717) → heading in page 8 (719). The presentation material structure analysis unit 113 outputs structural relationship information representing these structural relationships to the progress support information generation unit 112 (step 608).

  FIG. 8 is a flowchart showing the processing contents of the progress support information generating unit 112. The progress support information generation unit 112 receives presentation material information, interest vector information, and structure relation information as inputs and operates (step 801). First, importance is assigned to structurally related display units from the interest level vector information and the structure relation information (step 802). The importance level represents a degree that should be emphasized in explaining. There are various ways of giving importance, but here, the interest level of the interest level vector is simply given to all the display units connected by the structural relationship. For example, taking the interest level vector Z (710) in FIG. 7 as an example, the interest level with respect to the display unit 7 is 1, and the structural relationship is page 5 → page 7, page 7 → page 8, page 7 → page 9. is there. If the interest level 1 is assigned to these related pages as the importance level, page 5: importance level 1, page 7: importance level 2, page 8: importance level 1, page 9: importance level 1 are obtained. The importance may be treated as a vector by adding the attribute of the original character string of interest. In this way, the interest string A has an importance level of 1, the interest string B has an importance level of 2, and the entire page has an importance level of 3, but the interest string B is more important. it can.

  Next, the explanation amount for each topic is calculated from the consumption time so far, and the importance of the display unit is corrected (step 803). In other words, topics that have already been fully explained should not be treated as important, even if they are highly important. Conversely, for important topics that have not taken much time for the sake of explanation, more time is taken when they appear again. In the simplest case, the value of the explanation amount is defined as ((actual explanation time-scheduled required time) / scheduled required time), and this is calculated for the page where the interest degree vector giving importance to the page has a structural relationship. Subtract from the importance of the next page. For example, if a page written as “company-specific property” is spoken more than planned, the importance of the place where the same topic appears next becomes low.

  Next, the explanation time of the unexplained part is calculated according to the importance assigned to each page, and there is a difference in the importance in the page, that is, there is a difference in the importance of headings and character strings If so, ask for topics that focus on the explanation. This is also a request for a topic that is not explained with great emphasis (step 804). Simply, the remaining time is proportionally allocated to the importance for each page. In this case, the range of increase / decrease with respect to the planned required time may be limited in consideration of the planned required time. A specific example of this part is shown in FIG.

  Finally, the progress support information generation unit 112 sends, as an output, progress support information indicating which part is to be described in detail and how much time should be used to the progress support information presenting unit 106 (step 805). The content of the progress support information may be rich according to the information presentation function. For example, as a result, the information indicating that the importance is high and the allocation time is long but the explanation amount correction is greatly received is sent as a part of the progress support information, so that the progress support information presenting unit 106 can be used. Give feedback to the presenter. The interest level vector information given as an input to the progress support information generation unit 112 may be input separately for each user role. As a result, it is possible to generate progress support information for each role. For example, if VIP is important, progress support information that is centered on the part desired by VIP, or progress according to the wishes of experts, triggers discussions. Can be obtained and sent to the progress support information presenting unit 106.

  FIG. 9 illustrates the processing result of the progress support information generation unit 112. A page (901) is taken on the horizontal axis, the interest level vector and its structural relation information are described above, and the importance, explanation amount, and explanation amount correction that the progress support information generation unit 112 obtains are described below. The vector contents and the structural relationship (with interest character string) of the interest level vectors X (708), Y (709), and Z (710) are shown as horizontal bars (902, 903, and 904). Of the horizontal bar, pages surrounded by a thick line indicate units of interest vector display, and pages surrounded by a thin line indicate pages having a structural relationship with the display unit. The character string in the page is a character string of interest. There may be a plurality of interest character strings. Dotted lines are pages that have no direct structural relationship.

  The importance of each page is determined according to step 802. That is, the pages 3, 4, 6, and 9 that are structurally related to the interest level vector X having the interest level 2 have two importance levels (for "company-specific properties") and the interest level having the interest level -1. Pages 4, 6 and 9 that are structurally related to the vector Y have importance −1 (for “company-specific properties”), and pages 5, 7, and 8 that are structurally related to the interest level vector Z having the interest level 1. , 9 is assigned importance +1 for each character string of interest. The importance regarding the same character string of interest can be treated as being subtracted.

  Next, the explanation amount (906) of each page is obtained according to step 803. If the presenter explained page 3 of the planned 2 minutes in 3 minutes and page 5 of the planned 2 minutes in 1 minute, the explanation amount of page 3 is (190 seconds-120 seconds) / 120 seconds = +0.5, The explanation amount of page 5 is (60 seconds−120 seconds) / 120 seconds = −0.5.

  Next, the importance of each page is corrected based on the calculated explanation amount (907). The interest character string of the page 3 is “company-specific property” from the interest level vector X, and the page in which this interest character string appears next is 4. The interest character string of page 5 is “bidirectional link” from the interest level vector Z, and the page in which this interest character string appears next is seven. Therefore, the importance of page 4 is set to -0.5, and the importance of page 7 is set to +0.5 (908).

  As described above, the importance of each page and the importance for each character string of interest are obtained. Based on this value, the remaining time of 7 minutes is allocated to unexplained pages 6-9. The importance levels of the pages are +1, +2.5, +1, and +2, respectively. The simplest is to allocate time according to the importance ratio. That is, (7 / 5.5 × 1), (7 / 5.5 × 2.5), (7 / 5.5 × 1), (7 / 5.5 × 2) = (1.3 [min ], (3.2 [min]), (1.3 [min]), (2.5 [min]). Further, for example, for page 9, for example, “Web Service API” and “company-specific properties” are in conflict, and other topics are not particularly important. For example, “Web Service API” : “Characteristic peculiar to the company”: other = 1 = 1: 1: 1.

There are various methods of time allocation, and allocation may be performed in consideration of a ratio with a scheduled required time and an information amount of a display unit, for example, the number of characters and the number of headings.
FIG. 10 is a screen example of the progress support information presentation unit 106. An example of presentation materials (pages 3 (1001), 4 (1002), and 6 (1003)) presented to the audience terminal 108 through the audience presentation material providing unit 107 is on the left side, and the progress support information presentation unit 106 is used. Examples of presentation materials presented to the presenter (page 3 (1004), page 4 (1005), page 5 (1006)) are shown on the right. In this example, three types of progress support information of user roles (VIP, specialty) and general are generated and presented. Next to the title, place the progress support information on how to proceed with the entire page (1007, 1010, 1012). If the importance is high in the page and the explanation should be done carefully, emphasize the character string of interest and target the side. Roles and reference information are arranged (1009, 1011). In addition, the interest character string whose importance is high but whose importance has been reduced as a result of the explanation amount correction is presented as reference information (1013). On the other hand, for parts that are less important than other parts and for which the explanation time should be set elsewhere, the heading below the interest string (that is, the interest string of the middle headline is less important). For example, a cancellation line is drawn for the subheading, and the target roll and reference information are arranged on the side (1008). For reference information, display information is determined by static rules, for example, a characteristic action, for example, a part where the characterization has been performed is “slowly”, and a part that is structurally important is “detailed”.

  FIG. 11 shows an example of a screen of the progress support information presentation unit 106. This is a graph for bird's-eye view of not only the currently displayed page but also the entire future progress by displaying it in the page corner together with the progress support information of FIG. The horizontal axis takes time, and the color bars that abstract the entire audience and the progress support information for each roll are arranged vertically (1101, 1102, 1103). A color bar delimiter (1106) is a display unit, and a dark portion has a high importance and a light portion has a low importance. The character string of interest in the page may be written or popped up on this part. An up arrow (1104) is a page that a main audience belonging to the role is currently browsing. If there are a plurality of distribution peaks, a plurality of arrows may be arranged. The height of the mountain can be expressed by color intensity. The central axis (1105) represents the location currently being described. By referring to this figure, the presenter should be able to do what kind of pace allocation in the future in order to explain which layer is interested in which side of the presentation, for example, for VIPs. You can have a panoramic view.

  According to the embodiment described above, the presenter can grasp the interest level of the audience during the presentation, and can obtain a guide on how to adjust the presentation content. As a result, the contents of the explanation are more easily matched to the audience's interest, and the degree of understanding and favorable feeling of the audience is greatly improved. It is also easy to adjust the time distribution of explanations (for example, to shorten the time by omitting unimportant explanations) in order to secure more discussion time.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
