In addition to the map data and the like, the recording unit 8 also stores navigation data such as voice data necessary for guiding the movement of the vehicle and point information according to a first embodiment described later, etc., in a nonvolatile manner. is recorded as information on

The processing unit 5 includes a position calculation unit 50, a search condition setting unit 51, an information acquisition unit 52, an information extraction unit 53, a display content selection unit 54, and a display information control unit 55. ing. At this time, the position calculation unit 50, the search condition setting unit 51, the information acquisition unit 52, the information extraction unit 53, the display content selection unit 54, and the display information control unit 55 may each be configured by a so-called hardware logic circuit. Alternatively, it may be functionally realized by having the CPU in the processing unit 5 read and execute a program corresponding to a flowchart showing information providing processing according to the first embodiment, which will be described later. Further, the recording unit 8 corresponds to an example of the "storage means", an example of the "output means", and an example of the "feature feature information storage means" according to the present application, respectively, and the interface 1 corresponds to the "fourth acquisition unit" according to the present application. It corresponds to an example of "means" and an example of "fifth acquisition means", respectively. Furthermore, the operation unit 6 corresponds to an example of the "designating means", an example of the "display number setting means", and an example of the "deciding means" according to the present application, respectively, and the processing unit 5 corresponds to an example of the "presentation control means" according to the present application. and an example of "display control means", respectively. Furthermore, the display 9 corresponds to an example of the "display means" according to the present application, and the sensor section 7 corresponds to an example of the "position detection means" according to the present application.

On the other hand, in the recording unit 8, in addition to the navigation data, point information 80 according to the first embodiment, POI information 81 according to the first embodiment, and genre information 82 according to the first embodiment shown in FIG. and are recorded non-volatilely. At this time, as the point information 80, addresses of prefectures, cities, towns, villages, etc. as administrative divisions and data indicating the latitude/longitude of points corresponding to the addresses are associated and recorded in a non-volatile manner. As the POI information 81, as shown in FIG. 3(a), data indicating the names and addresses of facilities, features, etc. (that is, POIs) to be featured at a certain point are recorded in a non-volatile manner. there is Furthermore, as shown in FIG. 3B, the genre information 82 includes genre items for classifying and acquiring the content of the posted information recorded in the server device SV, and related words and phrases corresponding to each genre. , and information associated with each other is recorded. More specifically, the genre information 82 includes related words such as "soba," "udon," "pasta," "curry," "coffee shop," and "cafe," which may be included in the posted information. It is classified into genres and recorded non-volatilely. Similarly, related phrases that can be included in the posted information, such as "happy", "beautiful", "delicious", and "cool", are classified into genres of "impressions" and recorded in a non-volatile manner.

In the above configuration, the interface 1 controls transmission and reception of data between the processing section 5 and the recording section 8 under the control of the processing section 5 . Under the control of the processing unit 5, the interface 3 also controls transmission and reception of data between the information acquisition unit 52 of the processing unit 5 and the network NW. Furthermore, the sensor unit 7 provides current position data indicating the current position of the navigation device S itself (in other words, the current position of the vehicle or the like in which the navigation device S is mounted) from the self-contained sensor, the GPS sensor, the VICS sensor, and the like. Also, it generates traffic jam data and the like and outputs it to the processing unit 5 .

On the other hand, the position calculation section 50 of the processing section 5 calculates the current position of the navigation device S based on the current position data from the sensor section 7 . This current position is expressed, for example, by latitude/longitude indicating the current position. The position calculation unit 50 then 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 uses the calculated position information to search the post information recorded in the server device SV for the POI information characteristic of the current position. Set as a search condition. At this time, the search condition setting unit 51 exchanges with the recording unit 8 the address data recorded as the point information 80 in the recording unit 8 and the name data and address data recorded as the POI information 81. While doing so, the above search conditions are set.

Accordingly, the information acquisition unit 52 of the processing unit 5 uses the POI information set in the search condition setting unit 51 as a search condition, and acquires the posted information corresponding to the search condition from the server device SV that records the posted information. . 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, which is acquired from the server device SV by the information acquisition unit 52, and the user using the navigation device S sets the post information. Posted information containing the above-mentioned related phrases of the selected genre is extracted.

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

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

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 is generated by latitude/longitude and output to the search condition setting unit 51, which acquires the position information (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 out 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 in the process of step S1 as a search condition for the posted information recorded in the server device SV. and outputs the POI information 81 to the information acquisition unit 52 . For example, when the address corresponding to the latitude/longitude of the current position of the navigation device S is "Kashimada, Saiwai Ward, Kawasaki City, Kanagawa Prefecture", the POI shown in FIG. From the information 81, "Shin-Kawasaki Station" and "Kashimada overpass" corresponding to the address are set as search conditions. Note that the setting of the POI information 81 as the search condition by the search condition setting unit 51 may be configured to be performed at any timing depending on the situation. Alternatively, the POI information 81 as a search condition may be periodically changed (updated) in response to a change in the current position as the navigation device S moves, for example.

Next, the information acquisition unit 52 connects with the server device SV via the network NW (step S4). Then, the information acquisition unit 52 transmits a request for acquisition of 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). Accordingly, the information acquiring 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 the posted information to the information extracting unit 53 (step S6).

At this time, communication with the server device SV can use, for example, a wireless network conforming to WiMAX (Worldwide Interoperability for Microwave Access). Alternatively, it may be performed via a wireless LAN (Local Area Network). If 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 obtains the account information. Send to server device SV.

Further, when acquiring the posted information from a plurality of server devices SV, the information acquisition unit 52 connects to, for example, three server devices SV "A", "B" and "C" simultaneously or chronologically, The post information corresponding to the above search conditions may be configured to be acquired. Further, acquisition of posted information by the information acquisition unit 52 is performed at arbitrary timing depending on the situation. For example, the posting information may be automatically acquired at the timing when the search condition changes.

Next, the information extraction unit 53, to which the posted information corresponding to the POI information 81 as the search condition is output, text-analyzes the output posted information (posted information including the POI information 81 as the search condition). Then, based on the result of the text analysis, the information extraction unit 53 classifies the posted information output from the information acquisition unit 52 into predetermined genres (step S7). genre (see FIG. 3(b)) has been designated in advance using the operation unit 6, for example (step S8). If the genre is specified in the determination of step S8 (step S8; YES), the information extraction unit 53 proceeds to the process of step S11, which will be described later. On the other hand, if 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 the form of options on the display 9. (step S9), and if the displayed name is designated by, for example, the operating section 6, the designated name of the genre is obtained (step S10). Then, the information extraction unit 53 extracts the posted information including the related term of the genre specified by the user from the output posted information and outputs the posted information 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 phrase related to the item "meal" of the genre information 82 is extracted. .

At this time, the information extraction unit 53 may determine the extraction content based on the result of text analysis of the posted information without setting the genre. For example, if the result of text analysis of the obtained posted information includes many items including “fireworks”, the posted information may be classified/extracted as the posted information including fireworks and output to the display content selection unit 54 .

Next, the display content selection unit 54 of the processing unit 5 determines that the number of display range frames (see FIG. 5 described later) on the display 9 (in other words, the number of posted information) is set by the user of the navigation device S to, for example, the operation unit 6 (step S12). If the number is specified in the determination of step S12 (step S12; YES), the display content selection unit 54 proceeds to the process of step S15, which will be described later. On the other hand, if the number is not designated in the determination of 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. (step S13), and after that, when the number of display range frames is designated by, for example, the operating section 6 on the displayed designation screen, the designated number of display range frames is obtained (step S14).

Next, the display content selection unit 54 selects the number of displayed pieces of posted information output from the information extraction unit 53, their order, specific parts, etc., according to the specified number of display range frames, and displays the displayed information. Output to the control unit 55 (step S15). More specifically, for example, the number of specified display range frames (that is, the number of pieces 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 in each frame, the extracted posted information is selected as a group of n items.

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

Next, the display information control unit 55 acquires the content of the post information selected by the display content selection unit 54 (step S16), and further fits the content of the acquired post information within the display range frame on the display 9. is displayed (step S17). As a result of this display, for example, as shown in FIG. 5, posted information of different genres 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, 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, for example, by determining whether or not the power of the navigation device S is turned off (step S18). If the information providing process according to the first embodiment is not terminated in the determination of step S18 (step S18; NO), the processing unit 5 returns to step S1 to continue the information providing process. On the other hand, if the information providing process is terminated in the determination of step S18 (step S18; YES), the processing section 5 terminates 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 as information posted by a third party other than the user. is sent to the server device SV. Then, when posted information related to the transmitted POI information 81 is extracted and transmitted by the server device SV, 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 location is extracted and displayed from the posted information of a third party other than the user. can be recognized in correspondence with its current position. At this time, POI information 81 based on a specific location other than the current location, which the user has determined using the operation unit 6 to view various posted information, is used instead of the current location of the user. Posted information may 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, it is possible to display posted information related to the position of the point determined by the user and related to, for example, a facility that the user does not recognize at all. can be done.

In addition, since the posted information corresponding to the specified genre is displayed, the posted information desired by the user can be divided into genres and displayed accurately.

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

Furthermore, since the sensor unit 7 that detects the user's current position is provided, it is possible to display posted information related to the user's current position and related to, for example, a facility that the user does not recognize at all.

In addition, since the necessary POI information 81 is acquired from the POI information 81 recorded in the recording unit 8, it is possible to display posted information regarding, for example, a facility that the user does not recognize at all, in a complete navigation device S. can.

(II) Second Example Next, a second example, which is another example according to the embodiment, will be described with reference to FIGS. 6 to 9. FIG. FIG. 6 is a block diagram showing a schematic configuration of the navigation device according to the second embodiment, and FIG. 7 is a diagram illustrating contents of POI information according to the second embodiment. FIG. 8 is a flow chart showing the entire information providing process according to the second embodiment, and FIG. 9 is a flow chart showing the POI information extraction process according to the second embodiment. At this time, in FIG. 6, the same member numbers as the respective constituent members of the information processing device S are used for each constituent member of the example corresponding to each constituent member of the information processing device S according to the embodiment shown in FIG. ing. In FIG. 6, the same members as those of the navigation apparatus S according to the first embodiment shown in FIG. Further, in FIG. 8, the same step numbers are assigned to the same information provision processing as the information provision processing according to the first embodiment shown in FIG. 4, and the detailed explanation is omitted.

In the information providing process according to the first embodiment described above, the search condition setting unit 51 sets the POI information recorded in the recording unit 8 as the POI information 81 as the search condition without assigning weight to the POI information. On the other hand, in the information providing process according to the second embodiment described below, POI information that is generally well known is set as the search condition as the POI information used as the search condition. That is, in the information providing process according to the second embodiment, in the POI information recorded in the recording unit 8, the POI information actually included in the posted information acquired from the server device SV (for example, the name data of the facility). etc.) is determined as POI information about a "famous" facility or the like at that point, and this POI information is used as a search condition as POI information that is the feature of the point desired by the user of the navigation device S. As a result, posted information including POI information about generally well-known (that is, famous) facilities, etc. is acquired from the server device SV and displayed, thereby making it possible to obtain information related to the location related to the user of the navigation device S. Display various information.

That is, in the navigation device S2 according to the second embodiment, the POI information recorded in the recording unit 8 is POI information 85, as shown in FIG. At this time, as shown in FIG. 7, the POI information 85 additionally includes data indicating whether the facility or the like is "famous" in addition to the POI information 81 according to the first embodiment. In the following description, the data indicating whether or not the character is famous will simply be referred to as "famous data". This famous data is described as "O" when it is famous, and is described as "X" when it is not famous. In addition, when the determination of whether or not it is famous is not made, it is described as "Null", for example.

Then, based on the position information calculated by the position calculation unit 50, the search condition setting unit 51 of the processing unit 5 according to the second embodiment sends POI information about famous facilities that are characteristic of the current position to the server. It is set as a search condition for searching the posted information recorded in the device SV. At this time, the search condition setting unit 51 exchanges with the recording unit 8 the address data recorded as the point information 80 in the recording unit 8, the name data recorded as the POI information 85, the address data, and the above-mentioned name data. The search conditions are set while exchanging data.

Accordingly, the information acquisition unit 52 uses the POI information set in the search condition setting unit 51 as a search condition, and acquires the posted information corresponding to the search condition from the server device SV that records the posted information.

Then, the information extraction unit 53 text-analyzes the posted information including the address acquired from the server device SV by the information acquisition unit 52, and refers to the POI information 85 recorded in the recording unit 8, which is used as a search condition. By determining whether or not the POI information 85 is included in the posted information, it is determined whether the facility or the like of the POI information 85 is famous at the current position. In addition to this, the information extraction unit 53 text-analyzes the posted information including the POI information as the search condition, and refers to the genre information 82 recorded in the recording unit 8 to determine whether the user using the navigation device S Posted information containing the above-mentioned related phrases of the set genre is extracted.

The components of the navigation device S2 according to the second embodiment other than the search condition setting unit 51, the information acquisition unit 52, and the information extraction unit 53 are the same as the corresponding components of the navigation device S according to the first embodiment. Since they have similar functions, detailed description is omitted.

Next, the information provision processing according to the second embodiment will be described more specifically with reference to FIGS. 8 and 9. FIG.

As shown in FIG. 8, as the information providing process according to the second embodiment, first, the processes of steps S1 and S2 similar to the information providing process according to the first embodiment are performed by the position calculation unit 50 and the search condition setting unit 51. Executed by

Next, the search condition setting unit 51 sets the famous POI information 85 corresponding to the latitude/longitude point calculated in step S1 as a search condition for the posted information acquired from the server device SV. That is, the search condition setting unit 51 determines whether or not the POI information corresponding to the address read from the location information 80 is famous or not in the POI information 85 (that is, the POI information 85 at that time). , it is determined whether or not the POI information describes "o" or "x" as the famous data (step S20). If it is determined in step S20 that the POI information corresponding to the address read from the point information 80 is famous or not in the POI information 85 (step S20; YES), then the search condition setting unit 51 corresponds to the address read out from the point information 80 by the process of step S2, and is determined to be famous in the determination of step S20 (that is, "○" is described as the famous data). POI information is called from the POI information 81 (step S22). After that, the processing unit 5 including the search condition setting unit 51 executes the processing of steps S4 to S18 similar to the information provision processing according to the first embodiment for the POI information 85 read out by the processing of step S22. . More specifically, for example, if the address of the point corresponding to the latitude/longitude of the current position is "Kashimada, Saiwai Ward, Kawasaki City, Kanagawa Prefecture", the POI information 85 corresponding to that point has the famous data "○". "Shin-Kawasaki Station" is set as a search condition, and then the processing from step S4 to step S18 similar to the information providing processing according to the first embodiment is executed.

On the other hand, in the determination of step S20, the POI information corresponding to the address read from the point information 80 has not been determined as to whether or not it is famous in the POI information 85, and the famous data is blank ("Null"). (step S20; NO), the processing unit 5 including the search condition setting unit 51 separately performs a process of extracting famous POI information corresponding to the address read from the point information 80 by the process of step S2. Execute (step S21). After that, the search condition setting unit 51 executes the processing of step S22, and furthermore, the processing unit 5 performs steps S4 to S18 on the read-out famous POI information in steps S4 to S18, which are the same as the information provision processing according to the first embodiment. process.

Next, the POI information extraction processing in step S21 will be described more specifically with reference to FIG.

As the process of step S21, first, the search condition setting unit 51 acquires the address of the point of latitude/longitude calculated in the process of step S1, and sets it as a search condition (step S210). Next, the information acquisition unit 52 connects with the server device SV via the network NW (step S211). Then, the information acquiring unit 52 transmits a request for acquiring the posted information including the address set as the search condition by the process of step S210 to the server device SV (step S212). Thereby, the information acquisition unit 52 receives the posted information corresponding to the address as the search condition from the server device SV that transmitted the acquisition request, and outputs it to the information extraction unit 53 (step S213). Next, the information extraction unit 53 acquires the POI information 85 of the address set as the search condition (that is, the POI information 85 whose famous data is "Null") from the recording unit 8 (step S214). After that, the information extraction unit 53 text-analyzes the posted information output from the information acquisition unit 52, and determines whether or not the name of the facility, etc. of the POI information 85 acquired from the recording unit 8 is included in the posted information (step S215). ). In the judgment of step S215, if the name of the facility or the like of the POI information 85 acquired from the recording unit 8 is included in the posted information (step S215; YES), the information extraction unit 53 extracts the famous data of the POI information 85. "Null" is rewritten to "O" (step S216), and the process proceeds to step S3 shown in FIG. On the other hand, if it is determined in step S215 that the name of the facility in the POI information 85 acquired from the recording unit 8 is not included in the posted information (step S215; NO), the information extracting unit 53 extracts the famous data in the POI information 85. is rewritten from "Null" to "x" (that is, not "famous") (step S217), and the process proceeds to step S22 shown in FIG.

In the series of processes in step S21, referring to FIG. 7, for example, if the address of the point corresponding to the latitude/longitude of the current position is "Shin-Kawasaki, Saiwai-ku, Kawasaki-shi, Kanagawa", the corresponding point is "Shin-Kawasaki " is set as a search condition (see step S210), and post information including "Shin-Kawasaki" is acquired from the server device SV (see steps S211 to S213). Then, text analysis is performed on the acquired post information, and if the name of the facility corresponding to the corresponding point "Shin-Kawasaki" is included, but "Central Suite Shin-Kawasaki" is not included, "Shin-Kawasaki The famous data of "Twin Towers" is rewritten from "Null" to "○", and the famous data of "Central Suite Shin-Kawasaki" is rewritten from "Null" to "X" (see steps S216 and S217).

Regarding the POI information 85 illustrated in FIG. 7, there is no famous facility (POI) at the point of the facility used as the search condition (that is, the famous data of the POI information 85 are all "X" for the point). ), the address of the latitude/longitude point calculated by the position calculation unit 50 is set as a search condition by the search condition setting unit 51, and post information including the address of the current position is acquired from the server device SV, It can also be configured to be displayed as posted information related to the location. Also, the famous data of the POI information 85 may be updated at any timing depending on the situation. For example, when a predetermined period of time has elapsed since the date and time set in the famous data, the famous determination processing in steps S20 and S21 may be performed again to change the contents. Furthermore, setting of POI information as a search condition may be performed at any timing depending on the situation. For example, the POI information as a search condition may be periodically changed according to changes in the current position of the navigation device S.

As described above, according to the information providing process according to the second embodiment, in addition to the effects of the information providing process according to the first embodiment, famous data is recorded as the POI information 85 and the name is posted. Since only the POI information 85 that is included in the information (that is, that it is famous) is indicated by the famous data is transmitted to the server device SV as the search condition, the POI information included in the posted information is used as the search condition. , it is possible to acquire and display a wider variety of posted information related to the point determined by the user.

(III) Third Example Finally, a third example, which is still another example according to the embodiment, will be described with reference to FIGS. 10 to 12. FIG. FIG. 10 is a block diagram showing a schematic configuration of the navigation device according to the third embodiment, FIG. 11 is a diagram showing the contents of POI information according to the third embodiment, and FIG. It is a flow chart showing the entire information providing process according to. At this time, in FIG. 10, the same member numbers as the respective constituent members of the information processing device S are used for each constituent member of the example corresponding to each constituent member of the information processing device S according to the embodiment shown in FIG. ing.

In the information providing process according to the third embodiment described below, unlike the information providing process according to the first embodiment described above, POI information about facilities and the like that are easier to understand is used as the POI information used as the search condition. That is, in the information providing process according to the third embodiment, in the POI information recorded in the recording unit 8, the "characteristics" of the point itself where the facility etc. exists and the facility etc. as the POI recorded in the recording unit 8 Include and record the “characteristics” of Specifically, for example, "characteristics" of points such as "residential area", "commercial area", or "factory area" are recorded in advance in the point information as point characteristic data, and "station", "bridge", "commercial building" are recorded in advance. , "residential building" or "factory" are recorded in advance in the POI information as POI characteristic data. By designation of the user of the navigation device S, for example, a facility having characteristics strongly related to the characteristics of the point as the current position, in other words, "along" the characteristics of the point of the current position, or "melting into" the point etc. as POIs. Alternatively, a facility or the like that has characteristics that are weakly related to the characteristics of the point, in other words, facilities that are "not in line with" the characteristics of the current location, or that are "peculiar" at that point are selected as POIs. With these, POI information about facilities etc. that are easy to understand is set as a search condition, and post information including the POI information is obtained from the server device SV and displayed, thereby for example blending into the current location or Various information related to the location related to the user of the navigation device S can be displayed by being able to acquire posted information including unique facilities and the like.

That is, in the navigation device S3 according to the third embodiment, as shown in FIG. At this time, as illustrated in FIG. 11(a), the point information 86 additionally includes the point characteristic data indicating the characteristic of the point with respect to the POI information 81 according to the first embodiment. In addition, as shown in FIG. 11B, the POI information 87 additionally includes the POI characteristic data indicating the characteristics of facilities, etc. of the POI information in addition to the POI information 81 according to the first embodiment. there is

Then, based on the position information calculated by the position calculation unit 50, the search condition setting unit 51 of the processing unit 5 according to the third embodiment determines the relationship between the characteristics of the current position as the point information 86 and the characteristics as the POI information 87. POI information 87 about facilities that are easy to understand at the current location is selected based on the strength of the gender, and the POI information 86 is set as a search condition for the posted information. At this time, the search condition setting unit 51 communicates with the recording unit 8, the address data and the location characteristic data recorded as the point information 86 in the recording unit 8, the name data recorded as the POI information 87, While exchanging the address data and the POI characteristic data, the search conditions are set.

Next, the search condition setting unit 51 performs a so-called "thesaurus analysis" to determine the strength of the relationship between the identification of the latitude/longitude point calculated by the processing in step S1 and the characteristics of the facility or the like corresponding to the address of the point. (step S25). Next, the search condition setting unit 51 determines whether the strength/weakness of the characteristic relationship between the post information to be displayed and the location has been specified in advance by the user of the navigation device S using the operation unit 6, for example. It is determined whether or not (step S26). If strong/weak is designated in the determination of step S26 (step S26; YES), the search condition setting unit 51 proceeds to the processing of step S29 described later. On the other hand, if the strength/weakness is not designated in the determination of step S26 (step S26; NO), the search condition setting unit 51 displays, for example, a designation screen on the display 9 for designating the strength/weakness of the relevance. (step S27), and then acquires the strength/weakness of the relevance designated using the displayed designation screen (step S28).

Next, the search condition setting unit 51 displays posted information including POI information having a strong characteristic relationship with the location, with respect to the posted information to be displayed based on the specified strength/weakness of the relationship. is specified (step S29). If it is determined in step S29 that display of posted information including POI information with a high degree of relevance is specified (step S29; YES), the search condition setting unit 51 refers to the POI information 87 and The POI information 87 determined to be strongly related to the characteristics (see step S25) is acquired (step S31), and the POI information 87 is subjected to steps S4 to S18 similar to the information providing process according to the first embodiment. Execute the process. On the other hand, if it is determined in step S29 that display of posted information including POI information with weak relevance is specified (step S29; NO), search condition setting unit 51 refers to POI information 87 and The POI information 87 determined to have weak relevance to the characteristics of (see step S25) is acquired (step S30), and the POI information 87 is processed in steps S4 to S18 in the same manner as in the information providing process according to the first embodiment. process. At this time, for example, if the point corresponding to the latitude/longitude of the current position is "Shin-Kawasaki, Saiwai-ku, Kawasaki-shi, Kanagawa", the search condition setting unit 51 refers to the POI information 87 and determines that the characteristic of the point is "residential area". , and the characteristics of the POI information 87 regarding facilities, etc. at the corresponding point are "commercial building" or "residential building" (see FIG. 11(b)). Here, if the user of the navigation device S has designated "strong" for the relevance of the characteristic (step S29; see YES), the search condition setting unit 51 determines that the relevance to "residential area" is strong and The POI information 87 of "Central Suite Shin-Kawasaki", which has the characteristics of "residential building" which is easy to understand and blends into the location, is set as a search condition, and the processing of steps S4 to S18 is performed in the same manner as the information provision processing according to the first embodiment. to run. On the other hand, if the user has specified "weak" for the relevance of the property (step S29; see NO), the search condition setting unit 51 determines that the relevance to the "residential area" is weak and that point ``Shin-Kawasaki Twin Tower'', which has unique and easy-to-understand characteristics of ``commercial building'', is set as a search condition, and steps S4 to S18 are executed in the same manner as the information provision processing according to the first embodiment.

Here, the strength of the relationship between the characteristics of the point related to the point information 86 and the characteristics of the POI of the facility etc. as the POI information 87 is determined in advance as "strong" or "weak". You can leave it. Also, it is possible to configure so that POIs with facilities that are neither strong nor weak in relation to each other and are found everywhere are not selected. More specifically, for example, POIs with the characteristic of "road" such as "prefectural road xx" can be configured not to be selected as POIs that exist in "residential areas" and "commercial areas" as well. .

As described above, according to the information providing process according to the third embodiment, in addition to the effects of the information providing process according to the first embodiment, the point characteristic data is recorded as the point information 86 and the POI characteristic data is recorded as POI information 87 . Then, based on the point characteristic data and the POI characteristic data, only the POI information 87 related to the point characteristic data and the POI characteristic data is transmitted to the server apparatus SV as a search condition.
