However, this system provides the information of the area designated by the user as it is regardless of the information terminal device, that is, the current location of the user, in addition to the provided information being limited to entertainment.
In practice, however, the purpose of the map search or the need for the information provided is likely to differ depending on whether it is in the vicinity of the area specified by the user or in a remote place. Is not enough to meet the needs.

  For example, from the point of view of a specified map, it is necessary to have extraordinary information such as accommodation information rather than daily information such as entertainment information. Since the distance to the current position is not taken into consideration, it is impossible to provide such detailed information.

  In other words, many of the conventional information provisions such as advertisements are based on map information, but all of them are mainly intended to provide information when specified on the map or when approaching a position on the map. Thus, the distance from the current position of the user who has accessed the map information is not considered.

  In addition, when the map information is acquired by accessing the server device and displayed on the screen of the information terminal device, for example, the region where the business hotel is concentrated or the luxury hotel / inn for each region of the displayed map If there is a characteristic for each area such as an area where the concentration is concentrated, it is convenient if the characteristics of the area can be displayed by color coding or the like for each area on the map.

FIG.

Next, a processing procedure when the user requests the provision of map information by accessing the information providing server device 2 from the information terminal device 4 will be described.
FIG. 3 is a flowchart showing a procedure for making a map information request from the information terminal device 4 to the information providing server device 2.
First, the information terminal device 4 transmits a connection request to the information providing server device 2 (S101). This connection request includes terminal device identification information of the information terminal device 4, for example, a mobile phone number, an IP address, and a user ID, a password, etc. as necessary. When the connection request is received by the communication unit 21 of the information providing server device 2 (S102), processing on the information providing server device 2 side starts.
That is, the communication control unit 201 transmits a map information search screen to the information terminal device 4 (S103).

  The user of the information terminal device 4 displays the map information search screen transmitted from the information providing server device 2 (S104), and selects the map or inputs the place name to the information providing server device 2. Then, a request for providing map information, that is, a request input is performed (S105).

  When the communication control unit 201 receives this map information request (S106), the information providing server device 2 passes various information (terminal identification information, request reception time, location information) in the request to the history information management unit 203. The requested map is passed to the map information management means 202, and the map information management means 202 reads the requested map information from the map information DB 221 by the reading means (S107). The distance calculation means 205 obtains the position information (longitude / latitude information) of the location of the information terminal device 4 and the position information of the read map (for example, the longitude / latitude information of the center position: or a specific position (station, etc.)). The distance between the two positions is calculated based on the position information (S108).

  The area information management means 204 reads a search item list classified by the distance from the area information DB 223 based on the calculated distance (S109), and transmits the search item list to the information terminal device 4 (S110). The information terminal device 4 displays the search item list together with the map information transmitted on the display screen of the display unit 42 (S111), and the user selects the search item (S112).

The selected search item is transmitted to the information providing server 2 (S113). The search items transmitted to the information providing server 2 are transferred to the area information management means 204, where the area information management means 204 counts (accumulates) the transferred search items for each distance category (S114). The count value is stored in the search frequency table of the area information DB 223 (S115), the search item list is reviewed based on the count value, and the count value, that is, the frequency number is reflected in the search item list as necessary. Then, the region information is updated (S116), and the region information is read from the region information DB 223 based on the search item (S117).
Further, the area information management unit 204 edits the map received from the map information management unit 202 (for example, shading, coloring processing, or text so that a part of the blocks constituting the map information can be distinguished from other blocks). (S118). The information providing server device 2 transmits the edited map information and area information to the information terminal device 4 (S119), and the information terminal device 4 displays the information on the display screen of the display unit 42 (S120).

When the user selects a search item again from the display screen of the display unit 42 of the information terminal device 4 (S121), the selected search item is transmitted to the information providing server device 2 (S122). The area information management unit 204 reads out the area information corresponding to the search item from the area information DB 221 (S123), and at the same time, performs the enlargement process of the map received from the map information management unit 202 and the editing process described above as necessary. In step S124, the edited map information and area information are transmitted to the information terminal device 4 (S125), and the information terminal device 4 displays the information on the display screen of the display unit 42 (S126).
Hereinafter, the same processing is continued until the user finally obtains area information necessary.

FIG. 4 shows a search frequency table that displays the number of selections of search items in the area represented by the map, corresponding to a specific map.
The area information management means 204 updates the number of searches in the search frequency table by counting the number of times the search item of the area information is selected.
For example, the number of searches for gourmets is 100 times when a request for obtaining map information of 0 to less than 5 km is made, 150 times for 5 to 10 km, and 10 times for 200 or more. On the other hand, the number of times of searching for a hotel is, for example, 0 for less than 0 to 5 km, 3 for 5 to 10 km, and 50 for 200 or more. In that case, when the display order of the search item list is to display a map of neighborhood, for example, less than 10 km, gourmet is displayed as a search item with a higher priority than the hotel. In some cases, hotels may not be displayed as search items. On the contrary, at 200 km or more, priority is given to the display of the hotel, and the gourmet can lower the priority of the display or not display it.
As described above, for example, the search item for the area information on the display screen changes the display priority according to the search frequency. In this case, the search items in the search item list can be displayed by updating the frequency table at the accumulated frequency of the whole year, at each time, or in real time. Further, by specifying the information terminal, a search item list can be created for each operation terminal, that is, for each user.

According to this embodiment, as described above, when a request for map information is made from the information terminal device 4 to the information providing server device 2, the information providing server device 2 is based on the identification information of the information terminal device 4. The information terminal device 4 is specified, the position (longitude, latitude) is specified based on the position information, and on the other hand, position information (longitude, latitude) representing the center position of the requested map is calculated. And the distance from the information terminal device 4 is calculated.
Here, based on the obtained distance, the region information management unit 204 reads the search item list from the region information DB 223 and transmits it to the information terminal device 4 by the communication control unit 201, and the information terminal device 4 displays the display unit 42. The search item list is displayed together with the map requested to be acquired.
For this reason, the user can automatically obtain a region information item, that is, a search item list classified according to a distance (search distance) from, for example, the center position of the map at the same time by simply searching the map. In addition, when a search item is selected on the display screen of the display unit 42, the area information management unit 204 updates the search frequency table each time and updates the search item list when necessary by referring to the search frequency table. The search items with the highest needs can always be displayed on the screen.

FIG. 5 shows a display example on the display unit 42 of the information terminal device 4.
The area information is displayed at different scales, for example, in units of prefectures, cities, towns and villages, or less, depending on the map area specified at the time of requesting the map.

On the searched map display screen, for example, as shown in FIG. 5A, together with the map around the specific station searched, the blank area where the map is displayed, the left side in the illustrated example, as a search item, There are items such as hotels, sightseeing, gourmets, etc.
Here, when the user selects (clicks or touches) a hotel, the screen is switched to the screen illustrated in FIG. 5B. In the screen of FIG. 5B, along with the searched map, blocks with hatching or color coding are displayed on a part of the map and displayed separately from other blocks.

Here, it is a display example when the location of the information terminal device 4 and the position of the searched map are separated by a long distance, for example, 250 km, and is shaded so that the block A and the block B can be distinguished from other blocks. , Hatching, color coding, etc., and a description such as “A: District with many business hotels”, “B: District with many general inns / hotels”, etc. is displayed in a part of the map area.
Here, for example, if block A is selected, a list of business hotels in the area and facilities, charges, telephone numbers, e-mail addresses, URLs, etc. are displayed. If a specific business hotel is selected, the charges, facility contents, business hours, etc. are displayed. When the URL is selected and the URL is selected, the home page of the business hotel can be viewed, and accommodation reservations can be made from the reservation screen on the homepage.
When block B is selected on the display screen, a general inn or hotel list is displayed, and a reservation can be made in the same manner by performing an operation according to the display screen.

When displaying the area information together with the map of the location of the information terminal device 4 or a distance close to it (for example, within 10 km), for example, the gourmet area is shaded on the map as a block instead of the above hotel or inn. , Hatched and color-coded. In this case, the user operation is the same as that described for the business hotel.
In the case of various contents such as shopping, it is possible to search for terms after selecting a block, and to narrow down target shopping facilities such as department stores.

In addition, for example, when a gourmet is selected from the search item list of “Amusement, gourmet, sports, shopping, medical, etc.” on the display screen of FIG. 6A, characters such as Japanese, Western, Chinese, Ramen, Izakaya are displayed next. At the same time, blocks C and D are displayed on the map. Here, for example, when “ramen” is selected, as shown in FIG. 6B, the area where there are many ramen shops (area where the number of ramen shops existing within a predetermined area exceeds a predetermined value) is enlarged and displayed as a block. (Block C) is displayed, and at the same time, “This area is full of ramen shops” is displayed. Further, although not shown in the drawing, the position of the ramen store is displayed on the display map, and the service content, fee, etc. of the ramen store are displayed by selecting the ramen store on the map.
Furthermore, if a system that leaves evaluations by users of individual ramen shops as history information, it is possible to display ramen shops with high evaluations based on the history information in the order of evaluation, or as a system that allows the user to select according to their characteristics. It can also be constructed.

The information terminal device 4 may be of a stationary type as well as a mobile type, and the provided regional information is not only a thing but also a service such as a tourist guide or a traffic guide or a local landscape. Or it may be an event.
