Description

  The present invention relates to a technique for displaying a map.

  Conventionally, map display technology has been used to display an electronic map on a screen or to search for facility information included in a map. This type of technology provides a function for displaying a POI icon indicating the presence of various facilities (POI: Point of Interest) such as restaurants and objects on a display screen. The user can browse information (element information) such as the name of the POI icon and the URL of the home page by clicking the POI icon. However, in places where facilities such as urban areas are dense, there are problems such as POI icons being dense on the map, overlapping POI icons, and making it difficult to see roads on the map.

  In order to solve such a problem, in Patent Document 1, POIs concentrated in a certain area on a map are collectively displayed as a representative icon, and when a representative icon operation selection is received from a user, the representative icon A thumbnail in which each POI icon included in the representative icon is arranged on a map with a different scale is displayed nearby.

  In Non-Patent Document 1, although not in the field of map display, as a technology for displaying information, a character string input by the user or a character string selected by the user is placed at the center of the screen as a parent node, and the character string is displayed. A search function is disclosed in which related words (related words) are arranged radially from the center as child nodes, and related words in a hierarchical structure can be expanded in a manner that is easy to visually understand.

[1. Constitution〕
As shown in FIG. 1 (configuration diagram), the present embodiment relates to a map display device 1 (hereinafter also referred to as “the present device 1”) that displays a map including facility information in response to a request from a user.

  This apparatus 1 has, as a general computer configuration, at least an arithmetic control unit 6 such as a CPU, a storage device 7 such as an external storage device (HDD or the like) or a main memory, and a communication means 8 ( A LAN adapter, a display device D such as a liquid crystal display, an organic EL display or a CRT display, and an input device E such as a mouse, a keyboard and a touch panel.

  Further, in the present apparatus 1, elements such as each unit shown in FIG. 1 are realized by a predetermined computer program (not shown) stored (installed) in the storage device 7 in advance to control the arithmetic control unit 6. Among these elements, the information storage means can be realized in the storage device 7 in an arbitrary format such as various databases (also referred to as “DB”), files, data structures, variables such as arrays, system setting values, and the like.

  Of these storage means, the map data storage means 11 is means for storing map data (not shown) in a format such as a raster or a vector for each place or scale according to the prior art. As illustrated in FIG. 2A, the POI data storage unit 12 is a storage unit that stores POI data in which element information that is an element of information related to POI is hierarchized for each POI. Here, the element information is information related to the POI such as the name, position information, address, telephone number, menu, coupon, etc. in FIG. In the example of FIG. 2 (1), the first hierarchy of element information is the name, the second hierarchy is the name, location information, address, telephone number, menu, and coupon attribute name, and the third hierarchy is the second hierarchy. Are stored in a hierarchy as values corresponding to the attributes.

  The POI data is not limited to the above example, and may be stored in the form of an object database in which element information is hierarchized as illustrated in FIG. First, element information of the first layer includes “◯ × cafe”, the ID and position of “XX cafe” (indicated as “location” in FIG. 3, for example, latitude and longitude), and display. Operations and click operations are included. The display operation represents the content of the display process when the POI “Ox Cafe” is displayed on the map. In FIG. 3, information indicating “display POI name” is stored. In the click operation, information meaning “expand second layer” is stored as the contents of processing when the POI “◯ × cafe” icon is clicked.

  In FIG. 3, “address”, “phone number”, and “menu” are included as the element information of the second layer. For example, if “address”, the character string and position of the address (indicated as “location” in FIG. 3). Specifically, the latitude and longitude are included.) As the display operation, information indicating “display“ character string ”” (the contents of element information represented by “character string” in FIG. 3) (For example, “Akasaka, Minato-ku, Tokyo ...”)) is to be displayed. same as below. ), Information indicating “maximum zoom at“ location ”position” is stored as a click operation.

  In addition, as the lower layer object of the second layer element information “menu”, the third layer element information “Spaghettinapolitan” and “hamburger set meal” are stored. Each of these includes “price” and information meaning “display menu name and price” as a display operation.

  As illustrated in FIG. 2B, the icon storage unit 13 is a storage unit that stores icon image data for each icon type code. Here, the type code is a code corresponding to a type such as a representative icon or a POI icon, and an icon image of a form (color, size, shape, etc.) corresponding to the type is stored in association with the code. As an example of the form of the icon image, not only a picture representing a circle, but also a picture representing a building, a picture representing a specific landmark, an area for displaying element information as text, and the number of POIs included in the icon are displayed. For example, a balloon provided with a region to be used.

[2. Action)
[2-1. (Keyword input and POI search)
The overall processing procedure in the present embodiment configured as described above is shown in the flowchart of FIG. That is, in this embodiment, first, the search instruction receiving unit 14 receives a POI search request from the user (step S101). Specifically, as illustrated in FIG. 5, a keyword (for example, a place name, a business type, a facility) for searching for a POI from the user in the keyword input field 401 of the POI search screen 400 displayed on the display device D is displayed. A name and a combination thereof are input via the input device E, and a search instruction is received when the search button 402 is pressed. Note that the search instruction may be received by displaying the category 403 based on the region name or business type name on the POI search screen 400 and accepting selection input of the category.

  Then, the search means 15 searches the POI data storage means 12 based on the search request received from the user, and acquires a plurality of POI data (step S102). In addition, the search unit 15 acquires map data in a range corresponding to the positions of the plurality of POI data from the map data storage unit 11.

[2-2. (Map and icon display)
Subsequently, the representative icon generation means 16 determines that the acquired POI data has a predetermined relationship with each other (for example, the position of the POI data is within a predetermined range, is within the same facility, A representative icon for displaying POI data on POI data and displaying POI data on a map for POI data having a predetermined relationship. The image of the POI icon representing the other POI is acquired from the icon storage means 13, and the display means 17 displays the representative icon and the POI icon on the map (step S103).

  Specifically, as illustrated in FIG. 6, the representative icon RI and the POI icon IC are displayed in the map display area A displayed on the display device D. Here, the representative icon RI may display the form of the representative icon as an icon representing a facility if the predetermined relationship exists in the same facility. Further, the number of the plurality of POIs having the predetermined relationship may be displayed in the representative icon.

[2-3. Operation input reception and display element hierarchy determination processing]
Then, the input receiving means 18 accepts an operation input from the user to the display element (representative icon RI, POI icon IC or element information CI stored in the POI storage means) (step S104), and the non-display means 21 It is determined whether the display element that is the target of the operation input is not the lowermost display element in the hierarchically structured POI data (step S105).

  Specifically, if there is an operation input to the representative icon RI, since a POI that has been put together exists, it is determined that there is a lower display element. If it is an operation input to the POI icon or element information, it is determined whether or not the POI data storage means 12 has information of a lower layer than the POI icon or element information.

[2-4. Operation processing according to element information)
When it is determined that the display element that is the target of the operation input is the lowermost display element (step S106: “YES”), the arithmetic control unit 6 responds to the element information CI of the display element that has accepted the input. The operation process is performed (step S107), and the process returns to the process of accepting an operation input from the user (step S104). As an example of a specific mode of the operation process according to the element information of the display element, if the element information is a telephone number, a calling means (not shown) is activated in accordance with the click operation of the telephone number, and a telephone call is made to the telephone number Perform outgoing call processing. If the element information is a URL of a website or the like, a web browser (not shown) is activated in accordance with the click operation of the website, and a process of displaying the website that is the target of the URL is performed. If the element information is an address, the center point of the map display area is moved to the position indicated by the location of the element information according to the click operation of the address, and is zoomed. In the above example, it is assumed that each element information includes a click operation as shown in FIG. 3. However, the present invention is not limited to this, and the operation when each display element is clicked is separately defined. Also good.

[2-5. (Hidden processing)
If it is determined that the display element is not the lowermost display element (there is a lower display element) (step S106: “NO”), it is determined whether there is a lower display element that has been displayed among the display elements to be operated. (Step S108). When it is determined that there is no display element in the lower layer that has been displayed (step S109: “NO”), if there is another display element below the operation target display element, a process of making it non-displayed is performed (step S110).

  FIG. 7 shows a specific procedure of the process (step S110) for hiding if there is another display element below the display element to be operated. That is, first, the non-display unit 21 traces the hierarchical structure of the display element to be operated to the highest level (representative icon) (step S201), and is under the highest level and below the same hierarchy as the display element to be operated. The presence or absence of a display element is determined (step S202).

  Specifically, in FIG. 8, when the display element OI is input by the user, the non-display unit 21 follows the hierarchical structure of the display element OI to be operated, and is represented as the highest display element. Get to the icon RI. Next, when a hierarchical structure of a display element different from the operation target associated with the representative icon is traced, display elements EI1 to EI4 of the same hierarchy as the operation target display element are extracted. When the display elements below the display elements EI1 to EI4 are further traced, the display elements SI1 to SI3 below the display element EI1 are extracted, and it is determined that there is a display element below (step S203: “YES”). .

  If it is determined that there is a lower display element, the non-display unit 21 performs a process of hiding the lower display elements SI1 to SI3 (step S204), and moves to the next step. That is, when an operation input is received to a display element of a hierarchy to which the display element that is the base of expansion of the display element that is displayed in an expanded state or a higher hierarchy is received, the display is expanded and displayed. The displayed display element is not displayed. If it is determined that there is no lower display element (step S203: “NO”), the process moves to the next step.

[2-6. (Map scale and display element size change processing)
Subsequently, the display mode changing unit 20 determines a position where a new display element is to be displayed while maintaining the position of the display element or the representative icon that is the target of the operation from the user (step S111). When the position exists at the edge of the map display area (step S112: “YES”), the scale of the map and the size of the display element are changed (step S113).

  Specifically, as illustrated in FIG. 9, when the user performs an input operation on the display element OI to be operated among the display elements displayed in the map display area A, a new display element VI is displayed. If the position (indicated by the alternate long and short dash line in the figure) is to be displayed, and the position is included in the edge portion Z (outside the dashed rectangle) of the map display area, the currently displayed map Is changed to a scale that is smaller by one layer, and the size of the display element displayed on the map is changed to a smaller one.

[2-7. (Expanded display of display elements)
Then, the expansion means 19 expands and displays the display elements associated with the operation target display elements so as to be radially connected around the operation target display elements (step S114). Specifically, as illustrated in FIG. 10, the scale of the map is changed to one scale smaller (from 20 m to 50 m, scale display while the position of the representative icon RI on the map is held at the same position as FIG. 9. SC is also changed to 50 m), and the display elements (representative icon RI, POI icon IC, and element information CI) displayed in the map display area A are changed to a reduced size. Then, as illustrated in FIG. 11, the display elements RC1 and RC2 associated with the operation target display element OI are expanded and displayed so as to be radially connected around the display element of the operation target OI (step S114). Then, the process returns to the process of accepting an operation input from the user (step S104).

  Note that the position where a new display element is to be displayed is not included in the edge of the map display area while maintaining the position of the display element or the representative icon that is the target of the user's operation (step) S112: “NO”), without changing the scale of the map and the size of the display element, the display elements RC1 and RC2 associated with the display element OI to be operated are radiated around the display element of the operation target OI. A process of expanding and displaying so as to be connected to the user (step S114) is performed, and the process returns to a process of accepting an operation input from the user (step S104).

[2-8. (Map scale and display element size change processing)
When it is determined that there is a lower-layer display element that has been displayed in the operation target display element (step S109: “YES”), the non-display unit 21 hides the lower-layer display element that has been displayed. (Step S115), it is determined whether or not the display element displayed after the non-display process is fit in the predetermined center area of the map display area (step S116). In step S117: “YES”), the scale of the map and the size of the display element are changed (step S118), and the process returns to the process of accepting an operation input from the user (step S104). If it does not fit in the central area (step S117: “NO”), the process returns to the process of accepting an operation input from the user (step S104) without changing the scale of the map and the size of the display element.

  Here, the display element that is displayed after performing the non-display process following the process of non-displaying the display element in the lower layer that has been displayed (step S115) fits in the predetermined center area of the map display area. An example of the process of changing the scale of the map and the size of the display element (step S118) when it is determined (step S116) and if it falls within the center area (step S117: “YES”) is shown. As illustrated in FIG. 12, when the user performs an input operation on the display element OI among the display elements displayed in the map display area A, the non-display unit 21 displays the display below the display element OI. Processing to hide the elements SI1 to SI6 is performed (step S115). Then, as illustrated in FIG. 13, the display mode changing unit 20 displays all the display elements displayed in the map display area A after the display elements SI <b> 1 to SI <b> 6 are not displayed. It is determined whether or not it falls within the area CA (indicated by a broken line in the figure) (step S116). If it falls within the area (step S117: “YES”), as shown in FIG. 14, the currently displayed map And the display elements (representative icons RI and POI icons IC1 to IC5) displayed in the map display area A are changed to a scale one level higher (changed from 50 m to 20 m, scale display SC also changed to 20 m). The enlarged size is changed (step S118).

[3. effect〕
As described above, in this embodiment, a plurality of element information of each POI included in the representative icon is displayed radially as a hierarchical icon (for example, FIG. 8), and the hierarchy is expanded by accepting an icon selection operation from the user. Thus, when the icon can no longer be displayed in the display area (for example, FIG. 10), by changing the scale of the map and the size of the icon (for example, FIG. 11), the position of the representative icon on the map can be changed. The hierarchical POI information can be displayed in the map display area while keeping it.

  In particular, when the display element that is the target of the user's operation input is a display element that is higher than the display element that is displayed in an expanded manner (for example, FIG. 8), the display element that has already been expanded and displayed is not displayed. By displaying it, it is possible to display the map in an easy-to-view manner without displaying unnecessary information.

  In addition, when the number of display elements that remain on the map decreases and the position of those display elements fits in the center area of the map display area (for example, FIG. 13), the map scale and the size of the display elements are changed. (For example, FIG. 14) The hierarchical POI information can be displayed in the map display area while maintaining the position of the representative icon on the map.

  In addition, when a plurality of POIs having a predetermined relationship exist in the same facility, the representative icon is displayed as an icon representing the facility, so that all POIs included in the representative icon are the same facility information. It becomes possible to recognize visually.

  Further, by displaying the number of POIs included in the representative icon in the representative icon (for example, FIG. 5), it is possible to recognize the number of POIs included in the representative icon at a glance.

  By displaying POI data on a map using icons and text stored in advance, it is not necessary to generate a thumbnail each time a representative icon is selected. The element information of each POI included in the representative icon can be displayed without applying a processing load.
