Further, as the genre information 82, as illustrated in FIG. 3 (b), the items of the genre for classifying and acquiring the contents of the posted information recorded in the server device SV, and the related words and phrases corresponding to each genre. And, the information associated with is recorded. More specifically, as the genre information 82, related words such as "soba", "udon", "pasta", "curry", "coffee shop", "cafe", etc. that can be included in the above posted information are "meals". It is classified into the genre and recorded as non-volatile. Similarly, related words and phrases that can be included in the above posted information, such as "happy", "beautiful", "delicious", and "cool", are classified into the genre "impression" and recorded non-volatilely.

In the above configuration, the interface 1 controls the transfer of data between the processing unit 5 and the recording unit 8 under the control of the processing unit 5. Further, the interface 3 controls the exchange of data between the information acquisition unit 52 of the processing unit 5 and the network NW under the control of the processing unit 5. Further, the sensor unit 7 uses the self-supporting sensor, the GPS sensor, the VICS sensor, and the like to indicate the current position of the navigation device S itself (in other words, the current position of the vehicle or the like on which the navigation device S is mounted). And congestion data and the like are generated and output to the processing unit 5.

On the other hand, the position calculation unit 50 of the processing unit 5 calculates the current position of the navigation device S based on the current position data from the sensor unit 7. This current position is represented by, for example, the latitude / longitude indicating the current position. Then, the position calculation unit 50 generates position information indicating the current position indicated by the latitude / longitude, and outputs the position information to the search condition setting unit 51.

As a result, the search condition setting unit 51 of the processing unit 5 searches the posted information recorded in the server device SV for the POI information characteristic of the current position based on the calculated position information. Set as a search condition. At this time, the search condition setting unit 51 exchanges the address data recorded as the point information 80 in the recording unit 8 and the name data and the address data recorded as the POI information 81 with the recording unit 8. While doing so, set the above search conditions.

As a result, the information acquisition unit 52 of the processing unit 5 acquires the post information corresponding to the search condition from the server device SV that records the post information, using the POI information set in the search condition setting unit 51 as the search condition. .. In this case, the information acquisition unit 52 has a communication function for exchanging data with the server device SV via the network NW.

Next, the information extraction unit 53 of the processing unit 5 text-analyzes the posted information including the POI information as the search condition acquired from the server device SV by the information acquisition unit 52, and is set by the user who uses the navigation device S. Extract the posted information including the above related words and phrases of the genre.

On the other hand, the display content selection unit 54 of the processing unit 5 selects the display content including the number, order, and portion of the posted information extracted by the information extraction unit 53 according to the display range of the information on the display 9. Finally, the display information control unit 55 of the processing unit 5 displays the display content selected by the display content selection unit 54 on the display 9. At this time, the display information control unit 55 can change the display content by the user setting of the navigation device S.

Next, the information providing process according to the first embodiment will be described more specifically with reference to FIGS. 4 and 5.

As shown in FIG. 4, as the information providing process according to the first embodiment, the position calculation unit 50 first calculates the current position of the navigation device S based on the current position data from the sensor unit 7, and the position calculation unit 50 calculates the current position of the navigation device S. Is generated by latitude / longitude and output to the search condition setting unit 51, and the search condition setting unit 51 of the processing unit 5 acquires this (step S1). Then, the search condition setting unit 51 calls the address of the point corresponding to the latitude / longitude of the acquired position information from the point information 80 (step S2). At this time, the search condition setting unit 51 may use an existing technique for converting latitude / longitude into an address.

Next, the search condition setting unit 51 calls the POI information corresponding to the address read from the point information 80 from the POI information 81 (step S3). Then, the search condition setting unit 51 sets the POI information 81 corresponding to the address corresponding to the current position of the navigation device S calculated by the process of step S1 as the search condition for the posted information recorded in the server device SV. Then, the POI information 81 is output to the information acquisition unit 52. By the processing of steps S1 to S3, for example, when the address corresponding to the latitude / longitude of the current position of the navigation device S is "Kashimada, Saiwai-ku, Kawasaki-shi, Kanagawa", for example, the POI illustrated in FIG. 3A. From the information 81, "Shin-Kawasaki Station" and "Kashimada Overpass" corresponding to the address are set as search conditions. The POI information 81 as a search condition may be set by the search condition setting unit 51 at an arbitrary timing depending on the situation. Alternatively, for example, the POI information 81 as a search condition may be changed (updated) periodically in response to a change in the current position due to the movement of the navigation device S.

Next, the information acquisition unit 52 connects to the server device SV via the network NW (step S4). Then, the information acquisition unit 52 transmits a request for acquiring the posted information including the POI information 81 set as the search condition by the process of step S3 to the server device SV (step S5). As a result, the information acquisition unit 52 receives the posted information corresponding to the POI information 81 as the search condition from the server device SV that transmitted the POI information 81, and outputs it to the information extraction unit 53 (step S6).

At this time, for communication with the server device SV, for example, a wireless network compliant with WiMAX (Worldwide Interoperability for Microwave Access) can be used. Alternatively, it may be performed via a wireless LAN (Local Area Network). When so-called account information such as a user's name and password is required for communication with the server device SV, for example, the account information input by the operation unit 6 is temporarily stored, and the information acquisition unit 52 stores the account information. Send to the server device SV.

When the posted information is acquired from a plurality of server devices SVs, the information acquisition unit 52 connects to the three server devices SVs "A", "B", and "C" at the same time or in chronological order, for example. It may be configured to acquire each post information corresponding to the above search condition. Further, the information acquisition unit 52 acquires the posted information at an arbitrary timing depending on the situation. For example, it may be configured to automatically acquire the posted information when the above search condition changes.

Next, the information extraction unit 53 in which the posted information corresponding to the POI information 81 as the search condition is output performs text analysis of the output posted information (posted information including the POI information 81 as the search condition). Then, the information extraction unit 53 classifies the post information output from the information acquisition unit 52 into a predetermined genre based on the result of the text analysis (step S7), and the post information to be displayed by the user of the navigation device S. (See FIG. 3B) is determined in advance by using, for example, the operation unit 6 (step S8). When the genre is specified in the determination in step S8 (step S8; YES), the information extraction unit 53 shifts to the process of step S11 described later. On the other hand, when the genre is not specified in the determination in step S8 (step S8; NO), the information extraction unit 53 displays, for example, a preset number of genre names (FIG. 3 (b)) in an optional manner. It is displayed above (step S9), and then when the displayed name is designated by, for example, an operation by the operation unit 6, the name of the designated genre is acquired (step S10). Then, the information extraction unit 53 extracts the post information including the related words and phrases of the genre specified by the user from the output post information and outputs it to the display content selection unit 54 (step S11). More specifically, for example, when the genre set by the user of the navigation device S using the operation unit 6 is "meal", the posted information including the words and phrases related to the "meal" item of the genre information 82 is extracted. ..

At this time, the information extraction unit 53 may determine the extraction content from the result of text analysis of the posted information without setting the genre. For example, when there are many posted information including "fireworks" in the result of text analysis of the acquired posted information, it may be classified / extracted as posted information including fireworks and output to the display content selection unit 54.

Next, in the display content selection unit 54 of the processing unit 5, the number of display range frames (in other words, the number of posted information) on the display 9 (in other words, the number of posted information) is set by the user of the navigation device S, for example, the operation unit 6. Is used to determine whether or not it has been specified in advance (step S12). When the number is specified in the determination in step S12 (step S12; YES), the display content selection unit 54 shifts to the process of step S15 described later. On the other hand, when the number is not specified in the determination in step S12 (step S12; NO), the display content selection unit 54 displays a designation screen for designating the number of display range frames on the display 9 in the form of options. After that (step S13), when the number of display range frames is specified by, for example, an operation by the operation unit 6 on the displayed designated screen, the number of the designated display range frames is acquired (step S14).

Next, the display content selection unit 54 selects the display number of the posted information output from the information extraction unit 53, its order, a specific part, and the like according to the display range frame of the specified number, and displays the information. Output to the control unit 55 (step S15). More specifically, for example, the number of designated display range frames (that is, the number of posted information displayed using the display 9) is n (n is a natural number), and the posted information extracted by the information extraction unit 53. Is displayed one by one in each of the frames, the extracted post information is selected as a group of n items.

In this case, for example, based on the information indicating the posting date and time included in each posting information, n items may be selected as the display order from the oldest posting date and time. Further, the display amount and display timing of the display contents in each posted information may be changed according to the situation. For example, it is determined whether or not the navigation device S is moving based on the position information output from the position calculation unit 50, and if it is moving, only the related words of the genre included in the posted information are included in the posted information. It may be configured to be displayed as a part, while the full text of the posted information is displayed when it is stopped.

Next, the display information control unit 55 acquires the posted information of the content selected by the display content selection unit 54 (step S16), and further stores the content of the acquired posted information within the display range frame on the display 9. Is displayed (step S17). As the display result, for example, as illustrated in FIG. 5, different posting information of a genre designated by the user of the navigation device S is displayed in each of the five display range frames 90. In this case, the display information control unit 55 may switch the display range frames 90 every n frames, or may automatically scroll and switch the n frames. Further, for example, the scroll may be rewound by the user's operation using the operation unit 6 so that the already displayed display content can be viewed again.

After that, the processing unit 5 determines whether or not to end the information providing process according to the first embodiment by, for example, determining whether or not the power of the navigation device S has been turned off (step S18). If the information providing process according to the first embodiment is not completed in the determination in step S18 (step S18; NO), the processing unit 5 returns to step S1 and continues the information providing process. On the other hand, when the information providing process is terminated in the determination in step S18 (step S18; YES), the processing unit 5 ends the information providing process as it is.

As described above, according to the information providing process according to the first embodiment, the POI information 81 based on the current position of the user of the navigation device S is recorded with the posted information of a third party other than the user. Send to the server device SV. Then, when the posted information related to the transmitted POI information 81 is extracted by the server device SV and transmitted, the posted information is received and displayed on the display 9. Therefore, the posted information related to the POI information 81 based on the user's current position is extracted from the posted information of a third party other than the user and acquired / displayed, so that the user does not recognize the posted information at all, for example, the posted information about the facility. Can be recognized in correspondence with its own current position. At this time, the POI information 81 based on a specific point other than the current position, which is determined by the user using, for example, the operation unit 6 to see various posted information instead of the current position of the user, is used. The posted information may be configured to be acquired from the server device SV and displayed. In this case, since the POI information 81 based on the position of the point determined by the user is used, the posted information related to the position of the point determined by the user and which the user does not recognize at all, for example, is displayed. Can be done.

In addition, since the posted information corresponding to the designated genre is displayed, the posted information desired by the user can be accurately displayed by dividing it into genres.

Further, since the posted information is displayed separately using the display range frame 90, the posted information can be displayed in an easy-to-understand manner.

Furthermore, since the sensor unit 7 for detecting the current position of the user is provided, it is possible to display posted information related to the current position of the user and which the user does not recognize at all, for example, about a facility.

Further, since the necessary POI information 81 is acquired from the POI information 81 recorded in the recording unit 8, it is possible to display the posted information about the facility, for example, which the user does not recognize at all in one completed navigation device S. can.
