  First, the function and configuration of the map display system 1 according to the embodiment will be described with reference to FIGS.

  The map display system 1 is a computer system that generates map content based on a user instruction and provides the map content to the user. As shown in FIG. 1, the map display system 1 includes a mobile phone M owned by a user and a map server 10 that manages map content. The mobile phone M and the map server 10 can communicate with each other via a network N configured to include a mobile communication network.

  As shown in FIG. 1, the map server 10 includes a map database (map storage means) 11, a user attribute database (user information storage means) 12, a user preference database (user information storage means) 13, an object database (functional database). Object storage unit 14, reception unit (reception unit) 15, map acquisition unit (map acquisition unit) 16, user information acquisition unit (user information acquisition unit) 17, object acquisition unit (object acquisition unit) 18, generation unit (generation Means) 19 and a transmission unit (transmission means) 20.

  As shown in FIG. 2, the map server 10 includes a CPU 101 that executes an operating system, application programs, and the like, a main storage unit 102 that includes a ROM and a RAM, an auxiliary storage unit 103 that includes a hard disk, The communication control unit 104 includes a network card, an input unit 105 such as a keyboard and a mouse, and an output unit 106 such as a monitor. Each function of the map server 10 reads predetermined software on the CPU 101 and the main storage unit 102, operates the communication control unit 104 and the like under the control of the CPU 101, and stores data in the main storage unit 102 and the auxiliary storage unit 103. This is realized by reading and writing.

  Returning to FIG. 1, the map database 11 is a part for storing map data. The map data is prepared for generating a three-dimensional map. As shown in FIG. 3, the map data includes an area ID for identifying an area in a predetermined range, a description about the area, and the latitude and longitude of the center of the area. It is out. The size of each area may be arbitrarily determined (for example, a 1 km square section, etc.). The configuration of the map data is not limited to the configuration shown in FIG.

  The user attribute database 12 is a part that stores user information related to user attributes (hereinafter referred to as “attribute information”). As shown in FIG. 4, the attribute information includes a user ID for identifying the user, the gender of the user, and the age of the user. However, the configuration of the attribute information is not limited to this, and the attributes (gender and age) shown in FIG. 4 are not essential. For example, other attributes such as occupation may be included in the attribute information.

  The user preference database 13 is a part that stores user information related to user preferences (hereinafter referred to as “preference information”). As shown in FIG. 5, the preference information includes a user ID and a preference value for one or more items (such as “hamburg” and “car”). The preference value indicates the degree of preference for the item, and is represented by a numerical value in a predetermined range (for example, 0.0 to 5.0). The higher this number, the stronger the user likes the item (object). Note that items to be included in the preference information can be arbitrarily determined. Moreover, since it can be said that the preference information is a kind of attribute information, the preference information and the attribute information may be collected in one database (table).

  The object database 14 stores object information in which a three-dimensional object drawn on a map, a position of the object, and drawing conditions that are conditions of user information for drawing the object on the map are associated with each other. Part. An object is any artificial or natural object that can exist on the ground, such as a building, a signboard, a traffic light, or a plant.

  As shown in FIG. 6, the object information includes an object ID for identifying the object, a description about the object, a latitude / longitude where the object is located, and a drawing condition (filtering rule) for drawing the object on the map. Including. In FIG. 6, the drawing condition is set based on the user's attribute (age), but this condition may be set based on the user's preference. For example, it may be possible to set a drawing condition “(taste value related to stock)> 3.0” for the object “signboard of securities company”. There may also be an object that is always drawn regardless of the user's attributes and preferences. In that case, the drawing condition is set to “none”.

  The receiving unit 15 is a part that receives, from the mobile phone M, a user ID for identifying the user of the mobile phone M and position information indicating a predetermined location. These pieces of information are sent from the mobile phone M to the map server 10 when the user performs a predetermined operation to acquire a map. The receiving unit 15 outputs the user ID to the user information acquiring unit 17 and transmits the position information to the map acquiring unit 16.

  The map acquisition unit 16 is a part that reads out map data corresponding to an area within a predetermined range including a place indicated by the position information input from the reception unit 15 from the map database 11. If the position information indicates latitude and longitude, the map acquisition unit 16 may read the map data using the position information as it is. On the other hand, if the position information is information other than latitude and longitude (for example, address and area name), the map acquisition unit converts the information into latitude and longitude using a predetermined conversion table (not shown), and then The map data corresponding to the latitude and longitude may be read out.

  For example, when the map database 11 stores the map data shown in FIG. 3 and the user of the mobile phone M requests a map around Roppongi Station, the map acquisition unit 16 uses the area ID “005” by the above processing. Read map data. The map acquisition unit 16 outputs the read map data to the object acquisition unit 18. Hereinafter, an area indicated by the read map data is referred to as a “display area”.

  The user information acquisition unit 17 is a part that reads user information corresponding to the user ID input from the reception unit 15 from the user attribute database and the user preference database. The user information acquisition unit 17 outputs the read attribute information and preference information to the object acquisition unit 18.

  The object acquisition unit 18 is a part that reads from the object database 14 object information of an object that is located in the display area and for which the user information input from the user information acquisition unit 17 satisfies the drawing conditions. Specifically, the object acquisition unit 18 reads out object information corresponding to the latitude / longitude range corresponding to the input map data, and the input attribute information and preference information. For example, for two objects with object IDs “001” and “002” shown in FIG. 6, even if they are located in the display area, the user's age is 16 years or older. Otherwise it will not be read. The object acquisition unit 18 outputs the read object information to the generation unit 19 together with the map data and user information (attribute information and preference information).

  The generation unit 19 draws the object indicated by the object information input from the object acquisition unit 18 on the map (display area) indicated by the similarly input map data, thereby generating map content data (three-dimensional map). Is the part that generates The generation unit 19 outputs the generated map content data to the transmission unit 20.

  For example, the generation unit 19 generates map content data as shown in FIG. 7 (a) and 7 (b) are maps of the same point, but FIG. 7 (a) shows a consumer finance signboard A, whereas FIG. The sign A is not drawn. Such a display difference is caused by a difference in attributes or preferences of the user who requested the map.

  In addition, when the user's preference value for the drawn object is equal to or greater than a predetermined threshold, the generation unit 19 highlights the object. Specifically, the generation unit 19 compares the object information with the preference information and determines whether to highlight the object information. Examples of the highlighting method include, but are not limited to, balloons and blinking.

  For example, when the preference value regarding the item “golf” is equal to or greater than the threshold value, the generation unit 19 adds a balloon to an object related to the item (for example, a golf shop or a sign of a golf tool). FIGS. 8A and 8B are maps of the same point, but in FIG. 8A, a balloon B indicating that there is a golf shop X is drawn, whereas FIG. In b), the balloon B is not drawn. Such a difference in display is caused by a difference in preference of the user who requested the map.

  The transmission unit 20 is a part that transmits the map content data input from the generation unit 19 to the mobile phone M.

  Next, the operation of the map display system 1 shown in FIG. 1 will be described using FIG. 9, and the map display method according to the present embodiment will be described.

  When the user performs an operation for map acquisition and a user ID and position information are transmitted from the mobile phone M to the map server 10, the receiving unit 15 receives the information (step S11, receiving step). Then, the map acquisition part 16 reads the map data corresponding to position information from the map database 11 (step S12, map acquisition step). Subsequently, the user information acquisition unit 17 reads out attribute information and preference information corresponding to the user ID from the user attribute database 12 and the user preference database 13 (step S13, user information acquisition step).

  Subsequently, the object acquisition unit 18 reads out from the object database 14 object information that is located in the display area and in which the attribute information and the preference information satisfy the drawing conditions (step S14, object acquisition step). Subsequently, the generation unit 19 generates map content data by drawing those objects on the map indicated by the read map data (step S15, generation step). At this time, the generation unit 19 also highlights the object as necessary. Then, the transmission unit 20 transmits the content data to the mobile phone M (step S16, transmission step). Thereby, the map content is displayed on the mobile phone M, and the user can view a desired map.

  As described above, according to the present embodiment, drawing conditions for objects that can be drawn on a map are determined in advance based on user attributes. Then, when receiving the user ID and the position information from the mobile phone M, the map data of a predetermined range is read based on the position information, is located in the area indicated by the map data, and the user of the user of the mobile phone M Objects that match the attributes (satisfy drawing conditions) are read out. Then, the map content data on which the object is drawn is transmitted to the mobile phone M. Therefore, only an appropriate object can be displayed on the map according to the user attribute. For example, when the user is a child, it is possible to provide a map excluding information inappropriate for minors (such as a signboard of a sex shop).

  Moreover, according to this embodiment, since the object relevant to the item with a high degree of preference of a user is highlighted, the user can easily acquire information that matches his / her preference.

  The present invention has been described in detail based on the embodiments. However, the present invention is not limited to the above embodiment. The present invention can be modified in various ways as described below without departing from the scope of the invention.

  In the said embodiment, although the map display system 1 provided the three-dimensional map to the mobile telephone M, the map display system 1 may handle a two-dimensional map and a two-dimensional object.

  In the above embodiment, attribute information and preference information are used as user information. However, only one of the information may be used, or other user information may be used.

  In the above embodiment, the generation unit 19 executes the process of highlighting the object, but this process may be omitted.

  In the above embodiment, the mobile phone M is shown as a communication terminal. However, any mobile terminal such as a personal digital assistant (PDA) or a fixed terminal such as a personal computer may be used. Good.
