  However, these techniques have the following problems. First, with the technique described in Patent Document 1, it is impossible to change the display order of contents to be displayed and browse the contents. Further, in the techniques described in Patent Documents 2 and 3, since a document to be selected in advance is uniquely associated as data, it is not possible to call a document that is not associated. Therefore, even if these techniques are used, it is not possible to flexibly change the browsing method such as the content browsing order and content display according to the situation.

  The present invention has been made in view of the above problems. That is, an object of the present invention is to provide an information processing apparatus that flexibly changes the browsing order of content and outputs content suitable for explanation. Moreover, it aims at providing the method.

  An information processing apparatus according to the present invention has the following configuration. That is, an input means for inputting an electronic document in which the browsing order of contents constituting the electronic document is determined in advance, a recognition means for recognizing at least one real object, and a content related to the real object recognized by the recognition means Priority determining means for changing the browsing order and determining to browse the content; and output means for outputting the content based on the determination by the determining means.

  According to the present invention, it is possible to give priority to content appropriate for an explanation target and flexibly change the browsing order of the content.

  Hereinafter, embodiments (embodiments) for carrying out the present invention will be described with reference to the drawings.

(First embodiment)
In the present embodiment, a new browsing order of each page constituting an electronic document is created using a real object as a key. In the following description, a diagram, a table, a sentence, or a group of them constituting each page of an electronic document is referred to as content. In addition, in order to simplify the description, in this embodiment, it is assumed that the electronic document is a group of slides used in the presentation, and there is only one content in one slide. That is, unless there is a special explanation, content = slide.

  FIG. 1 is a schematic diagram showing an example of a scene having a problem to which the first embodiment of the present invention is applied. Here, it is assumed that two users are facing a business negotiation. In this scene, the user 101 explains the product A 104 placed on the table 103 to the user 102. User 101 is an explainer and user 102 is a viewer. In addition, the user 101 performs an explanation using a slide 106 projected on the table 103 by the projector 105 with camera. Here, let us consider a case where there is a request from the user 102 to hear about the product G107 different from the product A104. At this time, the user 101 searches for slides that can explain the product G107 from the explanation slide data prepared in advance. This slide, that is, one electronic document collected in the order in which the contents are explained, is called a scenario.

  FIG. 2 is a schematic diagram illustrating an example of data held by the user 101 in the first embodiment of the present invention. Multiple explanation scenarios are available. Here, a scenario that can make a transition from the current slide 201, that is, a collection of slides is shown. Among these slides, the slide 203 included in the scenario 202 can explain the product G 107 desired by the user 102. Therefore, the user 101 selects the scenario 202 as a new one to be used for explanation, and manually advances the page to the slide 203. However, the slide 203 is not on the next page of the current slide 201, and exists far behind. Therefore, it takes time and effort for the user 101 to manually advance the page until the slide 203 is displayed.

  FIG. 3 is a schematic diagram showing a processing result in the first embodiment of the present invention. When the product G107 is placed on the table 103, the product G107 is recognized by the projector with camera 105. A new scenario is created using the recognized product G107 as a key. In the scenario 301 created here, a slide 303 including an outline of the target product G is displayed next to the current slide 302. In addition, it is possible to prepare a slide 304 including detailed information on the product G as a slide to be used thereafter.

  Next, an apparatus for realizing this embodiment will be described in detail.

  FIG. 4 is a schematic diagram illustrating an example of a schematic configuration of the information processing apparatus according to the present embodiment. The information processing apparatus according to the present embodiment includes a CPU 401, an input device 402, an output device 403, an imaging device 404, a storage device 405, a RAM 406, a ROM 407, and a BUS 408 that connects them. The CPU 401 controls the information processing apparatus by executing a control program stored in the storage device 405. As the storage device 405, a hard disk, a flash memory, or the like can be used. The input device 402 inputs electronic data to be output through the output device 403. The output device 403 projects electronic data. The imaging device 404 images a real object that is a key for executing processing. The storage device 405 stores electronic data input from the input device 402. The RAM 406 temporarily stores various data from each component. The ROM 407 stores a control program such as a processing program.

  In the present embodiment, processing corresponding to each step of the flowchart described later is realized by software using the CPU 401, but part or all of the processing may be realized by hardware such as an electronic circuit. .

  FIG. 5 is a configuration diagram showing a functional configuration in the present embodiment. The electronic document input unit 501 receives input of electronic document data that the user wants to display. In the real object recognizing unit 502, the imaging apparatus 404 captures and recognizes a real object for requesting creation of a new browsing order of the content corresponding to the slide in the examples of FIGS. The browsing method change request unit 503 generates a browsing method change request in response to the real object recognized by the real object recognition unit 502. In the browsing method determination unit 504, the browsing history of the real object recognized by the real object recognition unit 502 and the content until a browsing method change request is generated from the browsing method change request unit 503 (browsing information including operation information) The order of browsing for new content is determined based on this. Even when the browsing method change request unit 503 does not explicitly issue a change request, the browsing method determination unit 504 browses new content when the real object recognition unit 502 recognizes the real object to be explained. The order may be determined. The electronic document output unit 505 displays content in accordance with the new content browsing order created by the browsing method determination unit 504. In the present embodiment, the projection is performed on the table surface by the output device 403.

  Next, processing of the information processing apparatus according to the present embodiment will be described with reference to the flowchart shown in FIG. First, in step S <b> 601, a scenario of an electronic document registered in advance in the storage device 405 by the user 101 using the input device 402 is output through the output device 403. Here, there may be a plurality of scenarios of electronic documents registered in the storage device 405 as shown in FIG. Therefore, when a plurality of items are registered, one of them is selected by the user 101 in step S601, and the selected electronic document is displayed. In step S602, the imaging device 404 captures an image on the table 103, and detects whether a new real object has been added. If it is detected that the object has been added, the process advances to step S603 to recognize what the object is. This is performed using a known general object recognition technique or the like. The feature of the captured real object image may be compared with the pre-registered image feature, and the real object may be recognized using the pre-registered image attribute information. In step S604, a slide to be displayed is determined and determined, that is, display control is performed using the recognized real object and the browsing history of the content browsed so far as a key. This is realized, for example, by performing sequence pattern mining using information as a key. In other words, the slides browsed so far are treated as series data, and when key information is input for this data, what is best to come next is mined.

  The process for determining the next slide to be displayed in step S604 will be described in detail. FIG. 7 is a schematic diagram illustrating an example of a determination processing method of the content browsing method determination unit in step S604. Here, the scenario 701 is the display order of the electronic document that is input and displayed first. In this description, it is assumed that during the description of the slide 702 for explaining the outline of the product C, a product G different from the product described in the slide 703 is placed and it is requested to explain the product G. Then, first, when the product G is placed, a slide related to the product G is searched. This is performed, for example, in such a way as to extract what was used when explaining the product G in the explanation history before this explanation. Moreover, you may extract the thing in which the image of the goods G is contained, and the thing in which the goods G are contained as tag information of a slide. At this time, the target is not limited to the same document, but the slides in all held electronic documents are targeted. Here, the slide extracted as a target may be a collection of a plurality of slides. In addition, when a plurality of contents are included in one slide, each of these contents is targeted. The change candidates for the slide 703 extracted in this way are represented as a tree structure 704. Next, the flow of explanation so far is regarded as series data, and the transition probability (frequency) for each slide that is a candidate for change is calculated from this data. In this method, the appropriateness of the frequency of each transition pattern is derived from the slide usage history etc. in advance by using sequence pattern mining, and then used. A number drawn in the vicinity of each candidate of the tree structure 704 is the probability (frequency). As a result, the transition is made to the one with the highest probability (frequency). Here, in the case of the tree structure 704, the slide 705 is selected because the transition probability (frequency) to the slide 705 for explaining the outline of the product G is the highest. The transition candidate slides may be displayed in the order of transition probability, and the user may be selected from them. Further, a threshold value of transition probability may be set, and if there is no candidate that exceeds the threshold value, an error may be returned and the process may not be performed.

  As a result of the mining, the next slide to be displayed is changed from the original, and the slide is displayed on the table 103 in step S605. After the display is completed, the process moves to step S606, and it is determined whether or not the operation is finished. For this determination, various methods such as inputting an end command to the apparatus, removing a real object from the table, and turning off the apparatus can be considered. If it is determined that the process has ended, the process ends. If it is determined that the process has not ended, the process returns to step S601. Further, when a new object is not detected in step S602, the process proceeds to this step, and it is determined whether or not the operation is finished.

  In this case, FIG. 8 shows an example of a data processing method actually performed in the electronic document data. Specifically, slide rearrangement 801, addition 802, deletion 803, and replacement 804 are performed. Each process will be described in detail.

  Rearrangement 801 is performed when a desired slide is included in the currently used scenario. For example, in FIG. 8, the slide 805 that was to be displayed fifth before the change is rearranged with priority given to the third. In the case of the example shown in FIG. 7, this rearrangement process is performed when the overview page of the product G is included in the currently used scenario, and then the original slide is returned.

  Next, addition 802 is performed when a corresponding slide is extracted from another scenario and added when there is no desired slide in the currently used scenario. For example, in FIG. 8, slide A806 that was not in the original scenario is added to the third display order. With the priority given to the slide A806, the display order of the slides that were originally the third and subsequent ones are shifted backward one by one. In the case of the example shown in FIG. 7, this additional process is performed when the overview page of the product G is included in another scenario that is not currently used and then the original slide is returned.

  The deletion 803 is performed when a desired slide is included in the currently used scenario and it is not necessary to touch another slide in the scenario. For example, in FIG. 8, the slide 807 that was to be displayed third in the original scenario is deleted. Prioritize other slides. In the case of the example in FIG. 7, this deletion process is performed when it is determined that the overview page of the product G is included in the scenario being used and there is no interest other than the product G from the operation history so far. Is done. This determination of whether or not there is interest is performed by applying the calculation of the transition probability (frequency) of the transition pattern by the above-described sequence pattern mining. For example, in this case, the transition probability (frequency) to the third slide is calculated from the operation history up to the second displayed slide, and whether or not the probability (frequency) is equal to or less than a threshold value. The operation history used at this time is sent from the input device 402 to the storage device 405 and saved every time various operations are performed. This operation history information is called to the CPU 401 that performs processing in response to a change request from the browsing method change request unit 503 or the real object recognition unit 502 detecting an object. As another example of this deletion 803, when the scenario is changed, the process returns to the original slide, that is, this processing is performed when there is not enough time to explain the slide when processing with the rearrangement pattern. This is prepared as one of a plurality of scenario creation results, and can be selected when the user determines that the time runs out, or the timer is set and processing is performed based on the remaining time. Conceivable.

  Finally, the replacement 804 is performed when there is no desired slide in the currently used scenario and it is not necessary to touch at least some of the slides in the current scenario. Specifically, a process of extracting a corresponding slide from another scenario and replacing it with a slide of the original scenario is performed. For example, in FIG. 8, the slide 808 that is displayed third and the slide 809 that is displayed fourth in the original scenario are replaced with the priority slide A810 and slide B811, respectively. In the case of the example in FIG. 7, the process as described above is performed when the overview page of the product G is included in another scenario that is not currently used, and then the original slide is not returned.

  In this way, as a scenario different from the original data, a scenario 706 is created in which the product C outline is the same as before the transition and is changed thereafter. After the transition, it may be moved to the slide arranged behind the originally transitioned slide, or the next transition slide may be selected by series pattern mining in the same manner as the above processing. In this embodiment, a projector with a camera in which an imaging device and an output device are integrated is used. However, the projector is not necessarily integrated. For example, a digital camera may be prepared as the imaging device and a display may be separately prepared as the output device.

  According to the present embodiment, a new content display scenario can be created using the real object acquired by the imaging device 404 and the browsing history of the content as keys. This makes it possible to easily select content that is not in a scenario that has been used in advance or that takes time to switch.

(Second Embodiment)
In the present embodiment, content in a scenario created using a real object as a key is displayed in the vicinity of the real object.

  In the following description of the second embodiment, description of the same contents as those of the first embodiment will be omitted, and parts different from the contents of the first embodiment will be described. The configuration of the information processing apparatus according to the present embodiment is the same as that of the first embodiment.

  As in the first embodiment, consider the scene of FIG. In this scene, as in the first embodiment, a new scenario is created using a real object as a key. When displaying a slide included in this scenario, if it can be emphasized that it is related to a real object, it will be easy to understand that a new scenario has been created from the real object. Therefore, by applying this embodiment, it is possible to clearly indicate that they are related.

  FIG. 9 shows the processing result of this embodiment. When this embodiment is applied, for example, a slide 902 displayed by a new scenario such as a scene 901 is displayed in the vicinity of a real object 903 that has become a key for scenario creation. In addition, when there are a plurality of contents in a slide, each of these contents is a search target. Therefore, for example, a sentence 905 that is one of the contents being slid like a scene 904 may be displayed and displayed in the vicinity of the real object 906 that is a key for scenario creation.

  The above processing is performed as follows. In step S604 of FIG. 6, the slide to be displayed is determined, and at the same time, the display position is determined using the browsing method determination unit 504. In this case, the display position of the slide is determined based on the position of the real object recognized by the real object recognition unit 502 as a place adjacent to the position or within a predetermined threshold. Note that the threshold value may be determined manually by the user, or may be determined based on the display area, the actual object, or the size of the slide. In addition, if a slide is displayed that is not related to the actual object where the scenario is progressing, it is displayed away from the vicinity of the actual object, for example, the position displayed before the actual object is placed. You may do it.

  According to the present embodiment, the content in the new display scenario created using the real object acquired by the imaging device 404 and the browsing history of the content as keys can be displayed in the vicinity of the real object. Thereby, it becomes possible to emphasize and display that the content and the real object are related.

(Third embodiment)
In the present embodiment, second content different from the first content being described is displayed in the vicinity of a real object related to the content.

  In the following description of the third embodiment, description of the same contents as those of the first and second embodiments will be omitted, and parts different from the contents of the first and second embodiments will be described. The configuration of the information processing apparatus according to the present embodiment is the same as that of the first embodiment.

  As in the first embodiment, consider the scene of FIG. In this scene, as in the first embodiment, a new scenario is created using a real object as a key. At this time, the actual object that was originally used for the description may be placed for reference, and the description may be made using a new scenario while touching the contents. Therefore, by applying this embodiment, it is possible to display a slide different from the slide being described.

  FIG. 10 shows the processing result of this embodiment. When this embodiment is applied, when a slide 1002 displayed by a new scenario such as the scene 1001 is described, a slide 1003 including information to be compared is displayed in the vicinity of the related real object A1004. Will come to be.

  The above processing is performed as follows. First, in step S603 of FIG. 6, the real object recognition unit 502 recognizes that the real object A1004 originally used for the description is placed in addition to the real object D1005 which is a key for scenario creation. In step S604, the slide to be displayed is determined, and at the same time, the display position of the slide 1003 that was originally displayed is also determined using the browsing method determination unit 504. This is based on the position of the real object A 1004 recognized by the real object recognizing unit 502 as a reference, and the display position of the slide is determined to be a location adjacent to the position or within a predetermined threshold. Note that the threshold value may be determined manually by the user, or may be determined based on the display area, the actual object, or the size of the slide. In addition, if a slide is displayed that is not related to the actual object where the scenario is progressing, it is displayed away from the vicinity of the actual object, for example, the position displayed before the actual object is placed. You may do it. At this time, since the slide 1003 is sub information to the last, the display size is displayed smaller than the slide 1002 used for explanation. Also, if the actual object that was originally described is placed, the related slide is not necessarily displayed. For example, only the slide that the user wants to keep is displayed. Good. Furthermore, since it is only necessary to display a related slide, for example, an outline of the real object A1004 or a slide related to a plurality of real objects may be displayed, which is different from the original slide and a part thereof. .

  According to the present embodiment, the second content different from the first content being described is displayed in the vicinity of the second real object that is acquired by the imaging device 404 and is different from the first real object being described. can do. As a result, the first content can be described with reference to the second content.

(Fourth embodiment)
In the present embodiment, a new content browsing order is created by using the context of the scene, which can be read from the content of a story exchanged in a scene using the device, the operation content of the device, or the like. In the following description, this context or intention is called a context.

  In the following description of the fourth embodiment, description of the same contents as those of the first to third embodiments will be omitted, and parts different from the contents of the first to third embodiments will be described. The configuration of the information processing apparatus according to the present embodiment is the same as that of the first embodiment.

  FIG. 11 is a schematic diagram showing an example of a scene having a problem to which the fourth embodiment of the present invention is applied. As an outline, as in FIG. 1, it is assumed that two users are facing a business negotiation. In this scene, the user 1101 is explaining the product A 1104 placed on the table 1103 to the user 1102. Further, the user 1101 performs an explanation using a slide 1106 projected on the table 1103 by the projector with camera 1105. Here, consider a case where there is a request from the user 1102 to hear about a product D1107 different from the product A1104. At this time, the user 1101 searches for slides that can explain the product D1107 from the explanation slide data prepared in advance. Here, in the negotiation, in addition to the slide browsing history, a plurality of types of information 1108 such as the content spoken and the location designated by the user are generated. Therefore, a more accurate scenario can be created by extracting the context 1109 of “price negotiation” in the scene shown in FIG. It becomes like this.

  FIG. 12 is a schematic diagram showing a processing result in the fourth embodiment of the present invention. Here, the electronic document input unit 1201 to the electronic document output unit 1205 are the same as the electronic document input unit 501 to the electronic document output unit 505 in FIG. In this embodiment, a context extraction unit 1206 is added to extract the context of the place where the apparatus is used. This is to extract the context of the field from various data obtained from the field where the present apparatus is used.

  Next, processing of the information processing apparatus according to the present embodiment will be described with reference to a flowchart shown in FIG. In the flowchart, steps S1301 to S1303 are the same as steps S601 to S603 in FIG. 6, and steps S1305 to S1307 are the same as steps S604 to S606. Therefore, here, step S1304 which is an added portion and step S1305 which is affected by the addition will be described.

  In step S1304, the context extraction unit 1206 is used to extract the context of the place where the apparatus is used. Using the extracted context, the recognized real object, and the browsing history of the slides browsed so far as keys, the estimation of the slide to be displayed in step S1305, that is, the display control is performed. The control itself is realized by performing sequence pattern mining using information as a key, as in step S604. FIG. 14 shows a schematic diagram of the processing result. In the scene of FIG. 11, since price negotiation is extracted as a context, for example, a scenario 1402 including a slide 1401 on which a price comparison table of a product A 1104 and a product D 1107 is placed is created.

  According to the present embodiment, it is possible to create a new content display scenario using the actual object and content browsing history acquired by the imaging device 404 and the context of the place where the device is used as keys. This makes it possible to easily select content that is not in a scenario that has been used in advance or that takes time to switch.

(Fifth embodiment)
In the present embodiment, a new content browsing order is created using a plurality of real objects as keys.

  In the following description of the fifth embodiment, description of the same contents as those of the first to fourth embodiments will be omitted, and parts different from the contents of the first to fourth embodiments will be described.

  FIG. 15 is a schematic diagram showing an example of a scene having a problem to which the fourth embodiment of the present invention is applied. As an outline, as in FIGS. 1 and 11, it is assumed that two users are facing a business negotiation. In this scene, consider a case where the user 1502 places two real objects, a product E1504 and a product F1505, which are different from the product A1503, on the table surface and requests to hear about the product E1504 and the product F1505. At this time, the user 1501 searches for slides that can explain the product E1504 and the product F1505 from the explanation slide data prepared in advance.

  The basic processing flow and processing contents are the same as in the first embodiment, and when using a context, they are the same as in the fourth embodiment. However, in the present embodiment, since a plurality of real objects are placed simultaneously, there are a plurality of real objects recognized by the real object recognition unit 502. At the same time, there are a plurality of pieces of real object information used by the browsing method determination unit 504. FIG. 16 shows a schematic diagram of a new scenario created in this way. Here, a scenario 1601 is generated in which a description slide 1603 of the product F is displayed next to the description slide 1602 of the product E.

  According to the present embodiment, a new display scenario of content can be created using a plurality of real objects acquired by the imaging device 404 and the browsing history of the content as keys. This makes it possible to easily select content that is not in a scenario that has been used in advance or that takes time to switch.

(Other embodiments)
Other embodiments include the following.

  Up to this point, the first to fifth embodiments have been described as being handled independently, but it is also possible to implement a combination of these. For example, a new scenario can be created using the context according to the fourth embodiment, and the content in the scenario can be displayed in the vicinity of the real object by implementing the second embodiment.

  As described above, more appropriate presentation information corresponding to the progress of the event can be selected and presented at a timing that does not interfere with the user.

  The present invention can also be realized by executing the following processing.
