  The processing of the information display device 1 has been described above.

  Hereinafter, each part is explained in full detail.

[About the estimation unit 11 and the first extraction unit 12]
FIG. 6 is an explanatory diagram of processing of the estimation unit 11 and the first extraction unit 12. The estimation unit 11 uses, for example, a sensor (for example, an acceleration sensor, a gyro sensor, an electronic compass, etc.) installed in the information display device 1 or the exhibition room 101, and the position Pt and the direction of the information display device 1 in the exhibition room 101. By measuring the direction Vt in which the information display device 1 faces and the direction Ut that determines the rotation angle of the information display device 1, the shooting direction of a camera (not shown) in the exhibition room is estimated.

  The first extraction unit 12 obtains the area 102 displayed on the display unit 18 based on the position and orientation of the information display device 1. The first extraction unit 12 extracts position information and attribute information of one or a plurality of exhibits included in the region 102 displayed on the display unit 18 from the first storage unit 51. At this time, a coordinate system 80 of (x, y, z) is defined in the exhibition room 101.

  Therefore, the position Pt and the orientations Vt and Ut of the information display device 1 obtained by the estimation unit 11 and the position Pe of the exhibit stored in the first storage unit 51 are represented by coordinates on the coordinate system 80.

  Note that the area 102 displayed on the display unit 18 is an area within a quadrangular pyramid indicated by a broken line in FIG. 6. The square pyramid is determined by the angle of view of a camera (not shown).

  FIG. 7 is a conceptual diagram showing the region 102. The fact that an exhibit is included in the area 102 means that the position information of the exhibit stored in the first storage unit 51 is included in the square pyramid. In the example of FIG. 7, the exhibits at positions Pe <b> 1 and Pe <b> 2 are included in the area 102, and the exhibits at positions Pe <b> 3, position Pe <b> 4, and position Pe <b> 5 are not included in the area 102.

  The first extraction unit 12 uses the position information and attribute information (for example, related object ID, keyword, commentary, genre, etc.) of the extracted exhibits (for example, the exhibits 501 and 502) to display the exhibits. The attribute information of other exhibits related to the item may be extracted from the first storage unit 51.

  Note that the first extraction unit 12 may be able to extract the location information and attribute information of the exhibit from the first storage unit 51 in accordance with the designation from the user 100. In this case, the first extraction unit 12 uses the search keyword designated by the user 100, the genre selected by the user 100, or the like from the first storage unit 51 by touch input, keypad input, voice input, or the like. Position information and attribute information are extracted.

[About the first calculator 13]
The first calculation unit 13 uses the position Pt, the orientations Vt and Ut, and the position information of one or more extracted exhibits (for example, the exhibits 501 and the exhibits 502) to display an image of the exhibit (for example, , The display position in the display coordinate system of the images 301 and 302) is calculated.

[About the second extraction unit 14]
The second extraction unit 14 includes position information and attribute information (for example, related object ID, keyword, commentary, genre, etc.) of the exhibits (for example, the exhibit 501 and the exhibit 502) extracted by the first extraction unit 12. The related information of the exhibit is extracted from the second storage unit 52 by using.

  For example, the second extraction unit 14 extracts a keyword or a word such as a proper noun included in the explanation from the attribute information of the exhibit 501 and stores the extracted word in the second storage unit 52 using the word. Related information may be extracted. Further, the second extraction unit 14 uses the extracted related information (for example, related object ID, keyword, commentary, genre, etc.) to send other related information related to the related information from the second storage unit 52. Further extraction may be performed.

[About Second Calculation Unit 16]
The second calculation unit 16 is based on the display position of the images (for example, the images 301 and 302) of the extracted exhibits (for example, the exhibits 501 and 502) on the display unit 18 and the related information on the exhibits. Thus, the display position of the related information of the exhibit to be displayed on the display unit 18 as a video (for example, video 401, 402, 403) is calculated. FIG. 8 is a flowchart showing the processing of the second calculation unit 16.

  The second calculation unit 16 selects an image of an exhibit (main exhibit) to be processed from one or a plurality of exhibits captured by a camera (not shown) and displayed on the display unit 18. (S201). For example, the distance from the center of the display unit 18 to the images of the plurality of exhibits displayed on the display unit 18 is obtained, and the image of the exhibit having the shortest distance (for example, the image 301 of the exhibit 501) is obtained. It may be selected as the video of the main exhibit.

  The second calculation unit 16 selects one video of an exhibit (sub-exhibit) that is also the target of processing from among a plurality of exhibits displayed on the display unit 18 other than the main exhibit. (S202). For example, the distance from the center of the display unit 18 to the images of a plurality of exhibits displayed on the display unit 18 is obtained, and the image of the exhibit having the longest distance (for example, the image 302 of the exhibit 502) is obtained. It may be selected as an image of the sub-exhibition.

  The second calculation unit 16 selects attribute information extracted from the first storage unit 51 for the main exhibit (for example, the exhibit 501) and the sub-exhibit (for example, the exhibit 502) (S203). For example, attribute information such as production age may be selected for an exhibit and price may be selected for a product. The attribute information itself does not necessarily have to be a numerical value. When attribute information that is not a numerical value is selected, the second calculation unit 16 may calculate a relevance level that expresses the degree of relevance between the genres to which the main exhibit and the subexhibit belong as a numerical value. For example, the technique described in Patent Document 2 may be used.

  The second calculation unit 16 defines an attribute coordinate axis 90 that passes through the attribute information of the main exhibit and the attribute information of the secondary exhibit (S204). FIG. 9 is an example of the attribute coordinate axis 90. For example, when the production age is used as the attribute information, the second calculation unit 16 sets the attribute coordinate axis 90 as the axis of the age. That is, the age is internally divided between the attribute information 201 of the main exhibit and the attribute value 401 of the sub exhibit, and the positive side of the attribute value 201 of the main exhibit and the negative side of the attribute value 401 of the sub exhibit are Divide the age.

  When there is one exhibit displayed on the display unit 18, the attribute coordinate axis 90 may be defined in a predetermined direction from the exhibit 501.

  As shown in FIG. 9A, the second calculation unit 16 uses the same type of attribute information about the related information as shown in FIG. 9A for the plurality of related information (601, 602) extracted by the second extraction unit 14. Arrange on the coordinate axis 90.

  The second calculation unit 16 determines the ratio of the distance from the related information (601, 602) on the attribute coordinate axis 90 to the main exhibit (exhibit 501) or the subexhibit (exhibit 502) from the related information on the display unit 18. The display position of the related information on the display unit 18 is calculated so as to be equal to the ratio of the distance to the main exhibit (exhibit 501) or sub-exhibit (exhibit 502) (S205).

  Here, when the attribute information 201 of the main exhibit and the attribute information 401 of the sub exhibit are the same, the second calculation unit 16 cannot determine the attribute coordinate axis 90. In this case, the second calculation unit 16 may select a different exhibit displayed on the display unit 18 as a sub-exhibit.

  Further, the second calculation unit 16 does not determine only one attribute information 401 of the sub-exhibit, but instead of the sub-exhibit on the negative side of the attribute information 201 of the main exhibit as shown in FIG. 9B. The attribute coordinate axis 90 may be defined by arranging the attribute information 401 and arranging the attribute information 402 of the subexhibit on the primary side of the attribute information 201 of the main exhibit.

  The ratio of the distance from the related information in the attribute value coordinate system 90 determined in this way to the main exhibit and the subexhibit is not limited to the single attribute coordinate axis 90, but is common to the age and genre, the genre, and the commentary. A plurality of attribute coordinate axes may be combined, such as the number of keyword co-occurrence, age, genre, and data type. In this case, the second calculation unit 16 assigns priorities to the attribute coordinate axes, and the related information in the display unit 18 satisfies the ratio of the distance from the related information to the main exhibit and the sub-exhibit in descending order of priority. The display position may be determined.

  Further, when calculating the display position of the related information on the display unit 18, the second calculation unit 16 defines a display coordinate system in advance, arranges the related information on the coordinate system, and then projects it on the display unit 18. May be performed. The display coordinate system is not limited to the two-dimensional coordinate system with the main exhibit as the origin, and a three-dimensional coordinate system, a polar coordinate system, or the like may be used.

[Processing contents of first generation unit 15 and second generation unit 17]
FIG. 10 is an explanatory diagram of processing of the first generation unit 15 and the second generation unit 17. The 1st production | generation part 15 produces | generates the 1st image regarding the attribute information of an exhibit. The first image related to the attribute information is an image of the attribute information of the exhibit extracted by the first extraction unit 12, and may be, for example, a caption of the exhibit shown by the image 311 in FIG.

  The display position of the image 311 may be the display position calculated by the first calculation unit 13. Here, the 1st production | generation part 15 may move a display position below so that the image regarding an exhibit may not interrupt | block the image | video of an exhibit. The distance to be moved may be changed according to the distance from the exhibit to the information display device 1. Further, the distance may be reflected on the image size. For example, the first image of an exhibit that is close to the distance may be large and the first image of an exhibit that is far away may be displayed small.

  Moreover, the 1st production | generation part 15 produces | generates the 1st image regarding the relevant information of an exhibit. That is, the first generation unit 15 displays related information images (photos of exhibits in other museums) extracted by the second extraction unit 14 and related information such as titles and genres as thumbnail images (images 321, 321). 322, 323) and captions (images 331, 332, 333).

  When the second generation unit 17 relates the exhibits extracted by the first extraction unit 12 from the first storage unit 51 and the related information extracted by the second extraction unit 14 from the second storage unit 52, the second generation unit 17 Displays a second image (eg, line segments 341, 342, 343).

  The second generation unit 17 may change the shape, color, and the like of the line segment according to the related state. For example, the color may be changed depending on whether it is defined as explicitly related to the first storage unit 51 or the second storage unit 52, when the genre matches, and when the character string in the commentary information or keyword matches. You may change it. Further, when an exhibit is present outside the screen, an arrow image or the like that guides the direction in which the exhibit exists may be displayed.

  Thereby, the user 100 can display the exhibits outside the screen on the display unit 18 by changing the direction of the information display device 1 so as to follow the arrow.

  By arranging related information as in this embodiment, in a situation where the exhibits in the exhibition room are arranged in chronological order, related information that is information on objects that are not arranged in the exhibition room is also exhibited. It is possible to display the image on the display unit 18 of the information display device 1 so as to be superimposed on the video imaged by the camera of the information display device 1 in a state where there is little deviation from the arrangement order. Thereby, the user 100 can easily browse information arranged in chronological order on the same screen regardless of the difference between the exhibit and the related information.

  Similarly, if the products are displayed in order of price at the actual store where the products are sold, in addition to the products that are in stock and installed in the store, information on the products that are not in stock in the store is also displayed. Regardless of the difference between the information of the actual product and the product that is not in stock, it is possible to easily browse the information in order of price on the same screen. Similarly, in an actual store such as a bookstore, by arranging in order of sales ranking, it becomes possible to easily browse information in the order of ranking on the same screen, regardless of the difference in information between the real product and the product not in stock. .

  In the present embodiment, an example in which the information display device 1 includes the first storage unit 51 and the second storage unit 52 has been described. However, the present invention is not limited to this. For example, information included in the first storage unit 51 and information included in the second storage unit 52 may exist on the network. In this case, the first extraction unit 12 may extract position information and attribute information from the network, and the second extraction unit 12 may extract related information from the network.

  That is, according to the present embodiment, the information display device 1 can easily show the relationship between a plurality of exhibits displayed on the display unit to the user. In addition, the position of the exhibits around the exhibition room related to the exhibits can be easily shown to the user. In addition, explanations related to the exhibit, related photos, and other exhibits that are not in the exhibition room can be easily displayed to the user.
