The calculation unit 102 reads the database and calculates an area where a facility having a name that partially matches the place name exists. In this case, it includes facilities whose names completely match the place names. And the calculation part 102 calculates an area based on the positional information on the plant | facility in which a name partially corresponds with a place name. The database stores facility names, location information (latitude and longitude), facility types, and the like.

The calculation unit 102 calculates the density (density) of the facility based on the location information of the facility, and calculates a plurality of areas for each density. For example, the density is divided into a plurality of stages, and the area of each density in each stage is calculated. And the several area according to density is displayed with a different display mode. For example, control is performed to display areas according to density in different colors or different shades.

The output unit 103 outputs the area calculated by the calculation unit 102.

Further, FIG. 1 shows a display device 110 connected to the information processing apparatus 100 by communication. The display device 110 includes a reception unit 111, a transmission unit 112, and a reception unit 113.

The reception unit 111 receives an input of a place name from the user. The transmission part 112 transmits the place name received by the reception part 111 to the server (information processing apparatus 100) in which the facility information is recorded. The receiving unit 113 receives information indicating an area in which a facility having a name partially matching the place name exists from the server (information processing apparatus 100).

As described above, the simple display device 110 having the communication function and the display function operates the facility search and transmits the facility search to the information processing device 100, and the information processing device 100 performs the information processing by the function of the calculation unit 102 or the like.

For example, the transmitted place name is acquired at the time of the output request of the display device 110 described above.

Next, the information processing apparatus 100 reads the database and calculates an area where a facility having a name that partially matches the place name exists (step S202). At this time, the calculation unit 102 calculates the density (density) of the facility based on the location information of the facility, and calculates a plurality of areas for each density. Then, the calculated area is output (step S203). For example, this area is transmitted and output to the display device 110 that requested the output.

(Server configuration example)
FIG. 4 is a block diagram illustrating an example of the hardware configuration of the server. The server has the same configuration as that shown in FIG. In these servers and display devices, the GPS unit 315, the various sensors 316, the camera 317, etc. shown in FIG. 3 are unnecessary.

The information processing apparatus 100 shown in FIG. 1 performs information processing by the CPU 401 executing a predetermined program using programs and data recorded in a ROM 402, a RAM 403, a magnetic disk 405, an optical disk 407, and the like provided in the server. Realize the function. The database is constructed on the magnetic disk 405 or the like.

Further, the navigation device 300 may have the function of the server 400 shown in FIG. In this case, since the navigation apparatus 300 mounted on the user's vehicle described above realizes the function of the server 400 (information processing system 100), the server 400 can be eliminated.

The function of the calculation unit 102 of the information processing apparatus 100 illustrated in FIG. 1 can be realized by the CPU 401 illustrated in FIG. 4 executing the information processing program. The functions of the acquisition unit 101 and the output unit 103 illustrated in FIG. 1 can be realized using the communication I / F 414 and the like illustrated in FIG.

For example, of the configuration of the navigation device 300 shown in FIG. 3, the display device 110 having a simple configuration including only the CPU 301, the ROM 302, the RAM 303, the display 313, the communication I / F 314, and the like may be used.

Further, if the display device 110 has a function of displaying map information, the area information can be acquired from the server 400 and the corresponding area can be superimposed on the map and displayed.

(Example of information processing in Example 1)
FIG. 5 is a flowchart illustrating an example of information processing according to the first embodiment. Each process performed by the navigation device 300 and the server 400 is described. First, the navigation apparatus 300 inputs a place name by a user operation or the like (step S501). As a result, the navigation device 300 transmits the place name to the server 400.

The server 400 receives the place name from the navigation device 300 as character information. Then, the server 400 searches the facility information stored in the database for a facility whose facility name and input character string match all or part (step S502).

Next, the server 400 performs density calculation on the two-dimensional coordinates from the coordinate information (latitude and longitude) of the corresponding facility information (step S503). At this time, the server 400 calculates the density (density) of each facility based on the positional information of the plurality of facilities. Then, a plurality of areas for each density are calculated. Details of the density calculation will be described later.

Then, the server 400 superimposes the shapes of a plurality of areas (regions) according to density on the map data, and outputs (transmits) the superimposed display data to the navigation device 300 (step S504). The navigation device 300 displays the shape (display image) of the area received from the server 400 (step S505). Thereby, the navigation apparatus 300 displays the area where the facility corresponding to the input place name exists, and can easily search for the corresponding facility.

In step S504, the server 400 transmits only the shapes (latitudes and longitudes) of a plurality of areas (regions) according to density to the navigation device 300. On the navigation device 300 side, the processing is performed on the display image in step S505. You may perform the process which superimposes the shape (latitude / longitude etc.) of an area (area). For example, the server 400 transmits a plurality of position coordinates on the outer edge of the shape of a plurality of areas (regions) according to density to the navigation device 300, and the navigation device 300 side connects the plurality of position coordinates to determine the density. The shape of a plurality of areas (regions) is calculated.

FIG. 6 is a chart showing an example of the data structure of the facility information held in the server. The database of the server 400 stores the facility information 600 shown in the figure. The facility information 600 has one record for each facility, and each record includes a facility name in which the name of the facility is recorded, a latitude and longitude indicating the position (coordinates) of the facility, and a facility type.

FIG. 7 is a flowchart showing the contents of a facility name search process based on facility information. The detailed process of step S502 is shown. First, the server 400 reads one record from the database (step S701), and reads a facility name column (item) in the record (step S702).

Next, it is determined whether a part of the facility name matches the input place name (step S703). In this determination, a facility name that completely matches the input place name is included. When a part of the facility name partially matches the input place name (step S703: Yes), step S704 is executed, and when a part of the facility name does not partially match the input place name (step S703: No) ), The process proceeds to step S705.

In step S704, a record in which a part of the facility name partially matches the input place name is recorded with a matching identifier (step S704), and it is determined whether it is the last line of the record (step S705). If the last line of the record has been reached (step S705: Yes), the above processing is terminated. If the last line of the record has not been reached (step S705: No), the process returns to step S701.

7 will be described in detail by taking the facility information 600 of FIG. 6 as an example. First, a record in which a character string “堺” that is an input place name exists is extracted. The first line “Tsubaki Clinic” and the second line “Large Beef Noodle East” are applicable, and “Barber Sarashina” is not applicable. Then, the server 400 sequentially examines all the rows recorded in the database and executes them until the last row is reached. Next, the server 400 calculates the shape of an area (region) including a plurality of corresponding facilities.

FIG. 8 is a flowchart showing the contents of density calculation processing of facility information. First, one record is read from the database (step S801). At this time, the record to be read is a record that partially matches the place name in which a part of the facility name is input in step S704, based on the identifier.

Next, the facility position (latitude and longitude) of the read record is read (step S802). Then, a predetermined area including the location of the facility is calculated (step S803). At this time, the number of facilities for each predetermined range is counted (counted up) using a mesh method, which will be described later, and stored (step S804). Thereafter, it is determined whether it is the last line of the facility information record corresponding to the density calculation using the density method (step S805). If it is the last line (step S805: Yes), it will transfer to step S806, and if it is not the last line (step S805: No), it will return to step S801.

Then, an area (region) having a density exceeding a predetermined threshold is extracted (step S806), and the above processing is terminated. In step S806, the density of the facility is divided into a plurality of stages by dividing the count number into a plurality of stages, and a plurality of areas (regions) according to the number of facilities are calculated.

FIG. 9 to FIG. 11 are diagrams for explaining an example of calculation processing of areas by density of facilities using the mesh method and the density method, respectively. In the mesh method, as shown in FIG. 9, a plurality of meshes are provided by dividing a predetermined range into rectangles for each unit area on a map corresponding to an input place name, and the number of facilities included in each short form (mesh) is determined. Count. In the density method, the result of counting the number of facilities is added to an adjacent mesh according to the distance, and a range for each density is obtained.

As shown in FIG. 9, it is assumed that the number of facilities in one rectangular predetermined range 901a to 901c is 5, 3, and 2, respectively. Next, assuming that the influence degree of the facility is attenuated by 1 for each unit mesh, the influence degree is added to the adjacent mesh.

When the influence degree of only the mesh with the number of facilities is expressed as shown in FIG. 10, the mesh around the number of facilities becomes 5 meshes as shown in FIG. The degree expands.

Then, adding the remaining 2 and 3 facility meshes in the same way, the result shown in FIG. 11 is obtained. The obtained result has five stages according to the number of facilities, and indicates an area (region) for each stage.

FIG. 12 is a diagram showing a display example of the shape of a plurality of areas according to density. The example of a display of the map screen 1200 displayed on the navigation apparatus 300 is shown. For example, it is assumed that an area where facilities including a character string “Omotesando” inputted as a place name are distributed is displayed. There is no address registration called “Omotesando”. On the map screen 1200, density information 1201 indicating the area of the facility corresponding to the character string “Omotesando” is displayed in a mesh shape, and the density information 1201 has a display mode according to a plurality of stages. To display.

These multiple stages are obtained by the above density method calculation. Then, the area 1201a having the highest density is displayed in red, the area 1201n having the lowest density is displayed in blue, and a color continuously changing from high density to low density is displayed between these areas. Not only the color is changed according to the density, but a single display color may be displayed as a density according to the density, or another display mode may be displayed.

(Example of information processing in Example 2)
The second embodiment is an example in which the same information processing as the first embodiment is performed without using a server. In the second embodiment, a predetermined information processing terminal such as a personal computer at home, the navigation device 300, or the like performs information processing.

FIG. 13 is a flowchart illustrating an information processing example according to the second embodiment. For example, each process performed by the navigation device 300 is described. Each process (steps S1301 to S1305) shown in FIG. 13 is the same as each process (steps S501 to S505) shown in the first embodiment (FIG. 5), and is different only in that it is executed by the navigation device 300. . As described above, since the single navigation device 300 has the above database and functions such as area calculation, a result can be obtained only by operating the navigation device 300 operated by the user without requiring access to the server. become able to.

(Example of information processing in Example 3)
Example 3 is an application example to facility search. In addition to the same processing as in the first and second embodiments, when searching for facilities inside the area (region) shape that is the processing result, as a result of the density calculation, the regions are rearranged in order from the region with the highest density.

FIG. 14 is a flowchart illustrating an information processing example according to the third embodiment. FIG. 14 shows each process performed by the navigation device 300 and the server 400. First, the navigation apparatus 300 designates and inputs a place name and a type of facility to be searched by a user operation or the like (step S1401), and the navigation apparatus 300 transmits the place name to the server 400.

The server 400 receives the place name from the navigation device 300 as character information. Then, the server 400 searches the facility information stored in the database for a facility whose facility name and input character string match all or part (step S1402).

Next, the server 400 performs density calculation on two-dimensional coordinates from the coordinate information (latitude and longitude) of the corresponding facility information (step S1403). Then, the server 400 outputs (transmits) the data of the shapes of a plurality of areas (regions) for each density to the navigation device 300 (step S1404).

Further, the server 400 searches the facility information for the facility corresponding to the designated type in the shape of the area (region) (step S1405). Then, the density calculation result is associated with the searched corresponding facility and sorted (step S1406), and the data of the sorting result is transmitted to the navigation device 300.

The navigation device 300 displays the area shape data received from the server 400 and the sort result data in a superimposed manner on the corresponding area on the map (step S1407).

In the above processing, the user inputs the type of facility in the navigation device 300 in addition to the place name to be searched. For example, it is assumed that the place name is Togakushi and the facility type is soba restaurant. The server 400 searches for a specified type of facility (soba restaurant) within the area (door-hidden) shape obtained as a result of the processing. Then, the server 400 associates the latitude / longitude information and the calculation result of the density information with the facility (soba restaurant) obtained from the search result, and stores the location name facility (Togakushi soba restaurant) to be searched. Sorting is performed in descending order of density, and the navigation apparatus 300 can obtain this sort result.

As mentioned above, by using the regional shape tabulation and the density calculation results, and highlighting the facilities that are highly relevant to the region by preferentially outputting the points with high density inside the shape indicated by the place name It can be displayed.

(Example of information processing in Example 4)
Example 4 is an application example to point search. In the fourth embodiment, an area (region) where facility names including place names are distributed is extracted from the database for the place name input by the user, and the result is displayed to the user. At this time, when there are a plurality of areas (regions) corresponding to the input place name, the individual areas (regions) are displayed to allow the user to select an area.

FIG. 15 is a flowchart illustrating an information processing example according to the fourth embodiment. Of the processes shown in FIG. 15, steps S1501 to S1505 are substantially the same as the processes (step S501 to step S505) shown in the first embodiment (FIG. 5), and a plurality of areas (regions) in step S1505. After the display, a predetermined point is selected by the user on the navigation device 300 side (step S1506), and information regarding the area (region) included in the corresponding point is displayed.

FIG. 16 is a diagram showing a display example when there are a plurality of areas corresponding to the place name. As illustrated, for example, it is assumed that there are three areas (“Ginza A” 1601a to “Ginza C” 1601c) on the display screen 1600 where facilities corresponding to the place name “Ginza” are concentrated.

In this case, the server 400 performs density calculation for each area (“Ginza A” 1601a to “Ginza C” 1601c), and transmits the data for each area to the navigation device 300. The navigation apparatus 300 receives a selection from each area (“Ginza A” 1601a to “Ginza C” 1601c) by the user and displays information on the selected area.

In the above process, point information is generated for each area in order to specify the area, and a point having the highest density in the area (region) is selected in order to select a representative point of each area (region). Should be set. In addition, when there are multiple place names that have been entered, sort from the widest area, sort from the area with the highest density, and display only one area with the highest sort order, or sort They can be displayed in order.

Furthermore, when the place names you entered are scattered throughout the country, there are facility areas that include the place names in the country, so you can preferentially select a predetermined area or select from the vicinity of your vehicle position in order. By performing this process, the search efficiency can be improved.

According to the embodiment described above, when a user searches for a spot, even if the user stores the concept of the spot with a place name that is a customary name instead of an address, the name of the place name is You can display frequently used areas on the map.

In the above description, the configuration in which an area in which a facility having a name that partially matches the name of the place is presented to the user when the user inputs the name of the place is described as an example. However, the present invention is not limited thereto. . For example, the user may input a facility name such as “sunshine” in addition to the place name. In this way, not only the place name but also the name of the facility, in order to present the corresponding area, the database stores a place name, a facility name such as “Sunshine”, and a list of facility names related to this place name. Keep it. This makes it possible to present to the user an area where a facility having a name including the character string of the facility name “sunshine” exists.

Moreover, although the user demonstrated the structure using the navigation apparatus which has a function of a client (display apparatus) or an information processing apparatus (server) in the Example, performing the same process also using another smart phone etc. Can do.

Note that the information processing method described in the present embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, and a DVD, and is executed by being read from the recording medium by the computer. The program may be a transmission medium that can be distributed via a network such as the Internet.
