Description

  The present invention relates to a geographic information control display method and apparatus and program for displaying geographic information and comment information on a map, and a computer-readable recording medium, and more particularly, linked to content on a network on a two-dimensional plane. The present invention relates to a geographic information control display method and apparatus and program for arranging a figure and navigating a user to content, and a computer-readable recording medium.

  So far, an Associa Guide has been proposed as a system for arranging and displaying a plurality of images representing content on a two-dimensional map (see, for example, Patent Document 1).

  In the Associa Guide, since all the arranged images are displayed on one screen, the two-dimensional map is reduced and presented to the user. Further, in order to display location information on the map, geographical information (eg, a label indicating a location such as Kanto or Kansai) is arranged on the map. The user can view the arrangement of the images displayed on one screen, enlarge a place of interest on the map, and move up, down, left and right. Here, the position of the arranged image is dynamically changed in the map enlargement, up / down / left / right operation.

  The Associa Guide zooms in and zooms in on a two-dimensional map by dynamically presenting to the user the entire image that has been scaled up, down, left, right, and left translated from the above map and images on the map. Offering out and bread.

  In addition, World Wide Navi is one that displays comment information superimposed on a two-dimensional map (for example, see Non-Patent Document 1).

In this World Wide Navi, the comment information from the user about the content is displayed in a balloon as if talking, and the user is encouraged to be interested in the content.

The movement operation information acquisition unit 1 and the information A user terminal 10 is connected to the display unit 2. Note that the user terminal 10 may be a PC (personal computer) or a terminal with a simple configuration having a zoom controller and a display panel.

  The movement operation information acquisition unit 1 detects a movement operation by the user from the user terminal 10 and outputs the detected position information to the display information acquisition unit 3.

  The information display unit 2 superimposes and displays the comment information and map information acquired from the display information calculation unit 4 and the display information acquisition unit 3 on the screen (map image) of the user terminal 10.

  The display information acquisition unit 3 searches the geographic information DB 5 and comment information DB 6 based on the position information, extracts the geographic information and comment information, and outputs them to the display information calculation unit 4.

  The display information calculation unit 4 determines the number of comment information to be displayed by using the number of geographic information extracted by the display information acquisition unit 3, the ratio of the maximum number, and the maximum number of comment information that can be displayed.

  The map information DB 5 is a database that is referred to by the display information acquisition unit 3, and includes, as shown in FIG. 4, items of geographic information ID, X coordinate, Y coordinate, display caption, URL, and ranking value.

  The comment information DB 6 is a database that is referred to by the display information acquisition unit 3, and includes comment ID, X coordinate, Y coordinate, comment title, comment content, and ranking value items as shown in FIG.

  In the following description, it is assumed that the display device 10 having the map information display interface shown in FIG. 6 is connected to the movement operation information acquisition unit 1 and the information display unit 2.

  Further, the maximum number M of geographic information displayed on the screen of the user terminal 10 is set to 10, and the maximum number S of comment information is set to 20.

  FIG. 7 is a flowchart of the geographic information control display operation according to the embodiment of the present invention.

  Step 101) When the user clicks the zoom controller 11 of the map information display interface shown in FIG. 6, the movement operation information acquisition unit 1 detects the movement operation, and displays the map on the upper left and lower right maps. The coordinates are transferred to the display information acquisition unit 3. Here, the upper left coordinates are (10, 10) and the lower right coordinates are (30, 40), and the coordinates of these two points are sent to the display information acquisition unit 3.

Step 102) When the display information acquisition unit 3 acquires the coordinates from the movement operation acquisition unit 1, the display information acquisition unit 3 accesses the geographic information DB 5 based on the coordinate values, and obtains the acquired two coordinates (10, 10), (30, 40). Search for included geographic information. Here, the search results are sorted in descending order of ranking values, and X _M items are extracted from the top.

Here, the maximum number of X _M is the M matter that is set in advance, the range of X _M becomes 0 ≦ X _M ≦ M.

  In the following description, M = 10 will be described for the sake of simplicity.

Step 103) Based on the received two coordinates, the display information acquisition unit 3 accesses the comment DB 6 and searches for comment information included in the two coordinates (10, 10), (30, 40). Here, the search results are sorted in descending order of ranking value against, to X _S matter extraction. Wherein the maximum number of X _S is a S matter which is set in advance. Here, in order to simplify the description, the description will be made assuming that S = 20 cases.

  Step 104) Here, the display information acquisition unit 3 determines whether or not there is the geographic information extracted in Step 102. If there is, the process proceeds to Step 105, and if not, the process proceeds to Step 108.

  Step 105) The display information acquisition unit 3 outputs the geographic information extracted in Step 102 and the comment information extracted in Step 103 to the display information calculation unit 4.

Step 106) The display information calculation unit 4 determines the number of geographic information and comment information to be displayed using the following formula based on the geographic information and comment information input from the display information acquisition unit 3. Here, it is assumed that the number of input geographic information is X _M and the number of comments is X _S.

・ Number of geographic information = X _M (X _M ≧ 1)
-Number of comment information = (1-X _M / M) × S
Here, the number of comments information determined by the above equation is equal to or larger than X _S, the number of comment information and X _S. In the present embodiment, a case where X _M = 8 and X _S = 20 will be described as an example. The number of geographic information and comment information is as follows.

・ Number of geographic information = 6
-Number of comment information = (1-6 / 10) × 20
= 2/5 × 20
= 8
Based on this numerical value, the top 6 rankings of geographic information and 8 comment information are displayed. The geographical information and comment information to be displayed are sent to the information display unit 2.

  Step 107) Upon receiving the geographic information and the comment information from the display information calculation unit 4, the information display unit 2 displays them on the map according to the X coordinate and Y coordinate of each information. The displayed example is shown in FIG. FIG. 8 displays geographic information on the map display unit 12, and 6 pieces of geographic information and 7 pieces of comment information are displayed based on the number of pieces of geographic information obtained as described above. Here, although seven pieces of comment information are displayed, it is not necessarily required to be eight pieces obtained above, and may be within the obtained number of displayed comments.

Step 108) If there is no extracted geographic information in Step 104, the display information acquisition unit 3 displays the coordinates (10,) on the screen displaying the map acquired by the display information acquisition unit 3 in Step 102. 10) From the lower right coordinates (30, 40), the coordinates of the center of the screen are calculated. here,
Center coordinates ((10 + 30) / 2, (10 + 40) / 2) = (20, 25)
Can be calculated.

  The display information acquisition unit 3 searches the geographic information DB 6 based on the coordinates at the center of the screen determined above, and extracts the geographic information closest to the coordinates (20, 25) at the center of the screen.

  Step 109) The display information acquisition unit 3 transfers the geographical information closest to the extracted coordinates at the center of the screen to the information display unit 2.

  Step 110) The information display unit 2 displays the geographic information and the comment information received from the display information acquisition unit 3 at a predetermined place on the screen of the user terminal 10 via the interface. Here, the comment information is displayed on the map based on the X coordinate and Y coordinate of the comment information. The geographic information is displayed at the upper left of the screen, and an example is shown in FIG. In the example of FIG. 9, when geographic information cannot be extracted in step 104, the geographic information “Lake Festival” that is closest to the center of the screen acquired by the display information acquisition unit 3 is displayed on the upper left of the screen.
