Thereby, in the terminal device 2, the acquisition unit 21a acquires the position code as the position information stored in advance in the storage unit 33 of the NFC tag 3 (S11).

  Subsequently, in the terminal device 2, the generation unit 21b generates a destination code (Dx; Destination Code) (S12). Specifically, the generation unit 21b transmits a station code (Sx; Station Code), a route code (Rx; Route Code), and a sightseeing spot code (Tx; Tourist Code) to the other route guidance in the terminal device 2, When application programs such as a route guide and a sightseeing guide are executed, they are acquired by cooperating with those applications, and a destination code is generated by combining these codes. For example, when Sx = 0000 (: general outside the station), Rx = 000 (: no route setting), and Tx = 000 (: no setting), the data is generated as Dx = 0000000000. However, this is an example, and the present invention is not limited to this.

  Next, in the terminal device 2, the request unit 21c requests the content distribution device 1 to distribute the content (S13). More specifically, the request unit 21c requests distribution of the content by transmitting the user ID, the language code, the position code, and the destination code to the content distribution device 1 via the communication unit 22. .

  In the content distribution device 1, the receiving unit 11a receives the user ID, the language code, the position code, and the destination code via the communication unit 12 (S14). Then, the extraction unit 11b refers to the first table of the content storage unit 15, extracts the ID of the second table specified from the position code and the destination court (S15), and stores the content based on the ID. The second table of the unit 15 is specified, and the holding status of the content corresponding to each selection item of 5W1H is confirmed with reference to the second table (S16). Then, under the control of the transmission control unit 11d, identification information for identifying the content holding status of each of the 5W1H selection items is transmitted via the communication unit 12 (S17).

  In the terminal device 2, the receiving unit 21d receives the identification information via the communication unit 22 (S18). Then, the display control unit 21e displays a 5W1H content type selection screen on the display unit 25 based on the identification information (S19). At this time, among the 5W1H selection items, the items having content are highlighted and the items not having content are turned off. Therefore, the user can instantly recognize the items from which the content can be obtained.

  In the terminal device 2, when an item for which content distribution is desired is selected by the user operating the operation unit 24 (S 20), the request unit 21 c sends the ID of the selected item via the communication unit 22. The content is transmitted to the content distribution device 1 (S21). At this time, if there are more sub-items for the selected item, the display on the display unit 25 is switched under the control of the display control unit 21e to urge the selection of the sub-items. When a small item is selected by the operation of the operation unit 24, the ID of the small item is also transmitted to the content distribution device 1 together.

  In the content distribution device 1, the receiving unit 11a receives the ID of the item and the sub-item via the communication unit 12 (S22), and the extracting unit 11b refers to the second table of the content storage unit 15 to The ID of the third table corresponding to the ID is specified (S23), and contents are extracted based on the ID of the small item and the language code with reference to the third table (S24). The contents include text data, still images, moving images, audio data, and the like. When processing or the like is required for these contents, the generation unit 11c performs the processing and generates an HTML file or the like. In the content distribution device 1, the transmission unit 11d transmits the content to the terminal device 2 via the communication unit 12 (S25).

  In the terminal device 2, the receiving unit 21d receives the content transmitted from the content distribution device 1 via the communication unit 22 (S26). Then, the content is displayed on the display unit 25 under the control of the display control unit 21e (S27). In this way, a series of processes related to content acquisition is completed.

  Here, an actual display example realized by the processing procedure described above with reference to FIG. 6 will be described in detail with reference to FIGS. 7 to 11.

When the terminal device 2 is held over the NFC tag 3 provided in the station yard, a screen 100 is displayed on the terminal device 2. In this example, a selection item of 5W1H is displayed. When the user taps an item desired to be distributed from the type item of the content, the screen is switched. In this example, it is assumed that “Which” is selected from 5W1H. When the item "Which" is selected, the display is switched to the screen 101, and the content of the route guidance is displayed. In this example, it is suggested in English that the platform of the XX station on the XX line is 250 m to the left.

  The example shown in FIG. 8 is for guiding a next generation car at a station platform. When the terminal device 2 is held over the NFC tag 3 disposed on the platform of the station, a screen 102 is displayed on the terminal device 2. In this example, a selection item of 5W1H is displayed. When the user touches an item desired to be delivered from the content type item, the screen is switched. In this example, it is assumed that When is selected from 5W1H. When the item When is selected, the display is switched to the screen 103, and the content of the guidance of the next generator is displayed. In this example, it is suggested in English that the XX line, XX station, and the next train depart from Platform 2 8 minutes and 30 seconds later.

  The example shown in FIG. 9 provides guidance on the current location, facilities, exits, and the like within the premises of the station. When the terminal device 2 is held over the NFC tag 3 provided in the premises of the station, a screen 104 is displayed on the terminal device 2. In this example, a selection item of 5W1H is displayed. When the user touches an item desired to be delivered from the content type item, the screen is switched. In this example, it is assumed that Where is selected from 5W1H. When the item “Where” is selected, the display is switched to the screen 105, and a detailed item is displayed. In this example, four detailed items of Here (current location), Toilet (toilet), Locker (coin locker), and Exit (exit) are displayed so as to be selectable. When the detailed item Here is tapped, the screen switches to the screen 106, and the content indicating the current position is displayed. In this example, the current position is indicated by a pointer on the map.

  The example shown in FIG. 10 is for guiding the details of a store at a store front or the like. When the terminal device 2 is held over the NFC tag 3 arranged at a store front or the like, a screen 107 is displayed on the terminal device 2. In this example, a selection item of 5W1H is displayed. When the user touches an item desired to be delivered from the content type item, the screen is switched. In this example, it is assumed that “What” is selected from 5W1H. When the item "What" is selected, the display is switched to the screen 108, and a detailed item is displayed. In this example, three sub-items, Inside (viewing), Menu (cooking menu), and Review (word-of-mouth), are displayed in a selectable manner. When the small item “Inside” is tapped, the screen is switched to the screen 109, and the content showing the preview is displayed. In this example, a photograph of the inside of the store is shown. On the other hand, as shown in FIG. 11, when the small item Review is tapped on the screen 108, the screen is switched to the screen 110 or the screen 111, and the content indicating word-of-mouth is displayed.

  Next, the structure of the first to third tables, their reference formats, and the relationship with the specified content will be described in detail with reference to FIGS.

  As shown in FIG. 12, the first table 200 has a structure in which the ID of the second table 201 to be referred next can be specified from the position code and the destination code. Note that station codes, route codes, and detailed installation information are merely described for management purposes. A plurality of second tables 201 are prepared, and each of them is assigned an ID. Each second table 201 has such a structure that the ID of the third table 202 to be referred next can be specified for each item of 5W1H. If there is a third table to be referred to for each item, the ID is recorded, and if not, Null is recorded. Therefore, by referring to the second table 202, the content to be distributed is held. Can be determined.

  A plurality of third tables 202 are prepared, and an ID is assigned to each of them. Each of the third tables 202 has a structure such that contents can be specified by small items and language codes. In other words, in each of the third tables 202, content in a plurality of languages is recorded for each sub-item. Here, the content is a concept including text data, still images, moving images, audio data, and the like.

  In the content distribution device 1, the extracting unit 11b refers to the first table 200 based on the position code and the destination code transmitted from the terminal device 1, and specifies the second table 201 to be referred next. In this example, the ID “A” of the second table is specified based on the position code 00003 and the destination code 000000000000. Then, with reference to the second table 201 of ID “A”, the ID of the third table to be referred next for each item of 5W1H is specified. At this time, since it is possible to determine that the item in which the ID of the third table is recorded has the content and the item that is not recorded does not have the content, the extraction unit 11b determines whether the content is retained / retained.

According to this table 207, a route is formed in the order of “1” → “2” → “3” → “4”, so if the current position is “1”, the process goes to “2” next. In the case of "2", it is possible to obtain appropriate information in combination with the contents specified by the position code and the destination code in the table 200 so as to go to "3" next. Become.

  Upon receiving the ID of the selected item from the terminal device 2, the extraction unit 11b refers to the second table 205 again, and sets the ID of the third table 206 to be referred next for the item specified by the ID. It specifies and refers to the corresponding third table 206 based on the ID. Then, the content to be distributed is specified based on the ID of the small item and the language code. In this example, since the item “Which” is selected, the ID of the third table 206 to be referred to is “c”. In this example, since there is no detailed item, the distribution target is specified as the content x based on the language code (02; English). The content specified by the above processing is the same as that shown in FIG.

  As described above, according to the embodiment of the present invention, short-range wireless communication is performed simply by holding a terminal device such as a smartphone over an NFC tag, which is a type of RFID tag, and the terminal device determines the position of the NFC tag. You can get the code. Then, when the terminal device transmits a content distribution request including the position code to the content distribution device, the terminal device can acquire and display the content corresponding to the position code and the like. At this time, on the terminal device side, the type of the content desired to be distributed can be selected from the selection items, so that the content that matches the user's needs, not the dictionary-like or guidebook-like content, can be accurately detected. It becomes possible to acquire. That is, it is not necessary to perform a troublesome input operation such as inputting a search keyword to a general search engine, and hold the terminal device over the NFC tag to select a content item desired to be distributed from simple selection items such as 5W1H. By simply selecting the type, the content desired by the user can be efficiently obtained.

  For example, if an NFC tag is installed in the station premises, various contents such as road guidance, transit guidance, current position guidance, departure time guidance, etc. in the station premises are offered to the user as desired. It becomes possible. Further, if an NFC tag is installed at a tourist spot, for example, if the installation location is a shrine, it is possible to appeal to and provide contents such as worship manners. Furthermore, if an NFC tag is installed in a shopping district, it is possible to check in advance the preview and menu of each store without entering the store.

  In addition, if the push notification is turned on at the time of user registration, it is possible to receive a suitable push notification based on the position information of the NFC tag.
