First, when the work information button 62 is pressed by the viewer, the portable information terminal 11 transmits a response request to the work tag 2 of the target work 9 (S01). When the response to the response request cannot be received (S02: No), the portable information terminal 11 transmits the response request to the work tag 2 again. On the other hand, when the response to the response request has been received (S02: Yes), the portable information terminal 11 acquires the work ID from the response (S03). When the acquired work ID is one (S04: Yes), the portable information terminal 11 reads the comment information of the corresponding work 9 from the memory card 13 based on the work ID and the set language, and displays it on the display 15. Display or output sound from the headphones 12 (S05). On the other hand, when there are a plurality of acquired work IDs (S04: No), the portable information terminal 11 displays a list of work names and author names corresponding to all of the acquired work IDs on the display 15 as selection candidates 18 (S06). ). In this case, the selection candidates 18 are displayed in the order based on the above-described radio wave intensity and / or viewing result data 52. Then, by the selection operation of the viewer, the portable information terminal 11 selects one candidate from the selection candidates 18 (S07), reads the commentary information of the work 9 corresponding to the selected candidate, and displays it on the display 15 Or sound output from the headphones 12 (S05).

  As described above, according to the present embodiment, when the viewer views the commentary information on the work 9, a response request is transmitted from the portable information terminal 11 to the work tag 2 (wireless tag). Even if a response (outgoing radio wave) is obtained from the work tag 2, one of the work tags 2 (work ID) is selected and the selected work tag 2 (work ID) is selected. The explanation information of the work 9 to be performed can be output to the portable information terminal 11. Thereby, the viewer can surely view (acquire) the commentary information of the desired work 9, and as a result, the satisfaction of the viewer can be improved. Moreover, since the guidance of the work 9 can be performed only by installing the work tag 2 for each work 9, it is possible to easily perform the system change work accompanying the redesign of the exhibition hall 8 or the like.

  In the present embodiment, it is assumed that the work tag 2 is installed in the vicinity of each work 9. However, the present invention is not limited to this. For example, a plurality of work tags 2 are installed at the same location. May be.

  Further, when the work tag 2 is read by the portable information terminal 11, it is possible to allow the viewer to confirm whether or not the work tag 2 has been read reliably (whether or not the work tag 2 has responded). preferable. In this case, for example, when the reading is successful, the work tag 2 may be lit to notify the viewer.

  Further, the mobile information terminal 11 may be provided with a wireless communication unit 49 to perform wireless communication with the exhibition hall server 5 (see FIG. 6). Thereby, for example, when updating the contents (explanation information) of the memory card 13 attached to the portable information terminal 11, the contents of the memory card 13 are downloaded by the portable information terminal 11 downloading the explanation information from the exhibition hall server 5. (Explanation information) can be updated. In this case, the commentary information may be updated after the exhibition hall 8 is closed, or downloaded and updated in real time whenever the commentary information in the exhibition hall server 5 is updated. Also good.

  In addition, information (such as a work ID) of the work tag 2 read by the portable information terminal 11 is transmitted to the exhibition hall server 5 via the wireless communication unit 49, and the exhibition hall server 5 aggregates the information. May be. In this case, for example, the exhibition hall manager changes the unpopular works to other works by analyzing the result of aggregation in the exhibition hall server 5 and grasping popular works / unpopular works. By doing so, it is possible to construct the exhibition hall 8 that can improve the satisfaction of the viewer.

  It is also possible to provide the functions of the portable information terminal 11 and the exhibition hall server 5 shown in the above example as programs. It is also possible to provide the program stored in a storage medium (not shown). As the recording medium, a CD-ROM, a flash ROM, a memory card (compact flash (registered trademark), smart media, memory stick, etc.), a compact disk, a magneto-optical disk, a digital versatile disk, a flexible disk, and the like can be used.

  In addition, the apparatus configuration and processing steps of the guidance system 1 can be appropriately changed without departing from the gist of the present invention, regardless of the above-described embodiment.
