The CPU 111 performs various arithmetic processes and performs centralized control of each unit. The RAM 112 has a work area for temporarily storing data when the CPU 111 performs arithmetic processing. The flash ROM 113 stores programs such as an operating system (OS) executed by the CPU 111, server software, and web applications.
The communication unit 12 performs processing according to a communication protocol such as TCP / IP, and transmits / receives data to / from the client 2 via the network N.

  In the search database 13, for example, contents (for example, web pages) provided by directory search are classified by category, and information regarding each content is registered for each content. The information on the content is, for example, title information, text information (simple / detailed description of the content), image information, link information, etc. constituting the web page, and is hereinafter referred to as content information.

This content information includes position information regarding the content. That is, position information is added to the content. Here, the location information related to the content is, for example, information that can specify the event venue in the case of content related to the event, and information that can specify the service providing location (store) in the case of content related to the restaurant. It is. This position information is represented by, for example, latitude / longitude, address, postal code, and the like.
In the search result screen, advertisement information for displaying an advertisement in conjunction with the content is associated with each content. This advertisement information is stored in an advertisement database 15 described later. For example, advertisement information (for example, an advertisement of a website that sells local special products) is associated with content related to an event. A plurality of pieces of advertisement information may be associated with one content.

  On the search result screen provided to the client 2, a predetermined display area is provided for each content extracted by directory search, and information (content information) and advertisement information related to the content corresponding to each display area are displayed.

  The map database 14 stores map information (map image data) obtained by scaling a predetermined area in multiple stages. The map information includes railway information indicating the status of railway installation, road information indicating the status of road installation, facility information indicating the location status of various facilities, and the like. The map information includes coordinate information associated with each point on the map image.

The advertisement database 15 stores advertisement information to be displayed in conjunction with the content. The advertisement information includes, for example, link information for making a transition to the advertisement requester's website from the search result screen, in addition to images and texts related to the advertisement requester's website.
For example, when a certain content is extracted by directory search, advertisement information associated with the content is displayed together with the content information.

In FIG. 2, the CPU 111 of the server 1 performs processing according to operation information from the client 2 by executing server software and a web application program stored in the flash ROM 113, for example. For example, when an operation for instructing a directory search is performed from the top page in the web browser of the client 2, data of a search result screen is generated and transmitted to the client 2.
In the client 2, the search result screen is displayed based on the screen data transmitted from the server 1.

FIG. 3 is a block diagram showing an outline of the hardware configuration of the client 2.
As shown in FIG. 3, the client 2 includes a control unit 21, a storage unit 22, a communication unit 23, an operation unit 24, a display unit 25, and the like, and each unit is electrically connected by a bus line 26. .

And the data of the web page (for example, top page of a portal site) transmitted from the server 1 are analyzed and displayed on the window of the web browser.

  As described above, when the server 1 provides a portal site to the client 2 and a directory search is performed in the client 2, a search result screen is displayed on the web browser of the client 2.

FIG. 4 is an explanatory diagram illustrating an example of a search result screen when a directory search is performed in the client 2. FIG. 4 is a search result screen displayed when a directory search is performed on the content (web page) of an event held in Hyogo Prefecture in the directory search service of the portal site. For example, in a directory search service, a desired search result can be obtained by performing directory transition of top> regional information>Kinki>Hyogo> life and culture> event.
Note that the search result screen D1 shown in FIG. 4 is almost the same as the search result screen provided by the conventional directory search.

In the search result screen D1 shown in FIG. 4, the content information CI1 to CI4 of the four contents 1 to 4 among the 20 contents 1 to 20 extracted by the directory search is displayed as a list. The contents 5 to 20 that are not displayed in FIG. 4 can be displayed by operating the scroll bar SB.
Each piece of content information of the contents 1 to 4 includes a title of the content and a simple description. For example, for the content 1, as the content information CI1, the title CI11 of the content “Amanaki Momiji Festival (Yobu City)” and the simple explanation CI12 of the content “Tenaki in the beautiful season of autumn leaves” are displayed. Has been.

In addition, check boxes CB1 to CB4 are provided corresponding to the contents 1 to 4, respectively. In FIG. 4, check boxes CB 1 and CB 3 are checked, and content 1 “Amanaki Momiji Festival (Yobu City)” and content 3 “Stork Sho Tajima Whole Impressive City (Toyooka City)” are selected. It is shown that.
A “learn more” button BT is provided in the lower area of the search result screen D1. When the “know more” button BT is operated, more detailed information about the selected contents 1 and 3 is displayed.

  In the present embodiment, as the detailed display when the “know more” button BT is operated, the selected content is displayed in association with the map image. In this detailed display, the display control method of the present invention is applied.

  FIG. 5 is a flowchart showing an example of a display control process for displaying a directory search search result screen (detailed display). This display control processing is realized, for example, when the CPU 111 of the server 1 executes server software and a web application stored in the ROM 113. For example, the search result screen D1 shown in FIG. 5 is displayed on the client 2, and is executed when the “know more” button BT is operated by the user.

In step S101, a virtual three-dimensional space defined by the X axis, Y axis, and Z axis is set. At this time, the Z axis is made parallel to the vertical direction of the screen. The X axis is preferably parallel to the horizontal direction of the screen. In this virtual three-dimensional space, the XY plane becomes a ground space for drawing a map image, and the XZ plane becomes an empty space for displaying information on content.
In step S102, position information added to the selected content is acquired. In FIG. 4, the check boxes CB1 and CB3 corresponding to the contents 1 and 3 are checked, so these contents 1 and 3 are contents to be displayed on the search result screen (detailed display).

In step 103, a map image including a point corresponding to the acquired position information is selected from the map database 14. When the point corresponding to the position information is in Japan, for example, a Japan map image is selected as an initial setting.
In step S104, the selected map image is drawn on the ground space (the XY plane of the virtual three-dimensional space). That is, the drawn map image is an image that is projected onto the XY plane when the terrain is viewed from above. Note that a general plan view map image may be rendered by performing image processing, or a perspective map image may be stored in the map database 14 in advance.

In step S105, the display area of the content to be displayed is set. At this time, a display area is set in an area that does not overlap the drawing area of the map image drawn on the XY plane. That is, the content display area is set in the sky space. The display area is an area where content information is arranged, and a display frame corresponding to the display area may be drawn.
The size of the display area is appropriately adjusted depending on the number of contents to be displayed and the content information. The arrangement of the display area is not particularly limited as long as it does not overlap with the drawing area of the map image.

  In step S106, a leader line connecting the point on the map image corresponding to the position information added to the content and the set display area is drawn. With this lead line, it is possible to easily recognize visually that the point on the map image is related to the content.

In step S107, content information is arranged in the set display area.
In step S108, advertisement information associated with the content is arranged in the set display area. Note that this process is omitted when the advertisement information is not associated with the content. When a plurality of pieces of advertisement information are associated with the content, display control is performed so that the advertisement display is switched at predetermined time intervals on the screen of the client 2.
In step S109, the screen data generated by the above process is transmitted to the client 2.

When there are a plurality of contents to be displayed, the processing in steps S105 to S108 is performed for each content to be displayed. At this time, it is desirable not to overlap the display areas of the contents.
In addition, by changing the display color of content information (text), display area, and leader line for each content (for example, display colors for related items are similar colors), even if there are multiple contents to be displayed, the map You can visually recognize the relationship between the point on the image and the content.

  As described above, in this embodiment, when information (content information) related to content to which position information (for example, latitude / longitude) is displayed on the screen, the ground space and the sky space are displayed on the screen. Is set (step S101), and a map image including a point corresponding to the position information added to the content is drawn in the ground space (steps S102 to S104). Then, the display area for displaying the content information is set on the empty space (the area that does not overlap with the drawing area of the map image) (step S105), and the content can be recognized in association with the corresponding point. The content information is displayed in the set display area (steps S106 to S108).

FIG. 6 is an explanatory diagram illustrating an example of a search result screen (detailed display) displayed on the client 2.
When the server 1 performs the display control process shown in FIG. 5, the client 2 displays the search result screen D <b> 2 shown in FIG. 6 based on the received screen data.
As shown in FIG. 6, a Japan map image MJ is arranged in the lower area (ground space) of the search result screen D2. Further, the content display areas AR1 and AR2 are set on the sky so as not to overlap the drawing area of the Japan map image MJ.

  FIG. 6 shows the detailed display of the content 1 of “Amanaki Momiji Festival (Yobu City)” and the content 3 of “Stork Shoko Tajima Marugoto Kando City (Toyooka City)” selected in FIG. In FIG. 6, a display frame is displayed corresponding to the content display area.

The display area AR1 of the content 1 of “Amanaki Momiji Festival (Yobu City)” is composed of a display area AR11 of content information I11 and a display area AR12 of advertisement information I12.
In the display area AR11, a title “Amanaki Momiji Festival” and a detailed description “A drop of 98m selected for“ Japan's 100 Best Waterfalls ”” are displayed as content information I11. In the display area AR12, an advertisement “Special product of Yabu City (Tajima beef)” is displayed as advertisement information associated with the content 1.
Then, the display area AR1 and the point (Yobu city) on the Japan map image MJ corresponding to the position information added to the content 1 are connected by a lead line L1.

The title of the content 3 is displayed as the content information I2 in the display area AR2 of the content 3 of "Guide for the Stork Sho Tajima Whole Impressive City". Since advertisement information is not associated with the content 3, only the content information is displayed in the display area AR2.
The point (Toyooka City) on the Japan map image MJ corresponding to the position information added to the display area AR2 and the content 3 is connected by a lead line L2.

  In FIG. 6, the display frame of the display area AR1 and the lead line L1 are indicated by solid lines, and the display area AR2 and the lead line L2 are indicated by dotted lines. However, this only indicates that the display mode is different. It is desirable to have different display colors. If the display area of the content and the display color of the content information (text) displayed in the display area are also similar to the lead lines, the relationship between the content and the corresponding point on the map image becomes clearer.

As described above, in the present embodiment, the content information that is the search result is displayed so as not to overlap the map image, so that the map image is not covered by the display of the content information, and the visibility of the map content is impaired. It will never be.
Further, since the display area of the content and the corresponding point on the map image are connected by a lead line with the corresponding point as a base point, the relevance between the displayed content and the corresponding point can be clearly recognized. Furthermore, when displaying information about multiple contents, the display color is different for each content, so even if multiple contents are displayed, the correspondence between the contents and points on the map image is unclear. Not.

In FIG. 6, the display positions of the content display areas AR <b> 1 and AR <b> 2 can be changed by a user operation. For example, the user can change the position of the display area by performing an operation of clicking and dragging the mouse cursor on the display area AR1 or the display area AR2.
That is, the display position of the display area can be changed based on a user operation. Thus, since the user can change the display area of the content to a desired position, the GUI is not only visually superior but also convenient.

The displayed content information is linked to a website that provides the content. For example, when the user clicks the display area AR11 of the content information I11, the content information is changed to the website. .
Similarly, the advertisement information displayed together with the content information is linked to the website of the advertisement requester, and when the user clicks on the advertisement information display area AR12, the website is shifted to the website.

FIG. 7 is an explanatory diagram schematically showing the arrangement configuration in the virtual three-dimensional space of the search result screen (detailed display) as shown in FIG.
As shown in FIG. 7, the map image MJ is arranged on an XY plane (ground space) in a virtual three-dimensional space defined by the X axis, the Y axis, and the Z axis. On the other hand, the content display areas AR1 and AR2 are formed on an empty space parallel to the XZ plane and having a height in the Z-axis direction.

Thus, displaying content information in an area that does not overlap with the map image MJ means displaying it at a position having a height in the Z direction from the XY plane on which the map image MJ is arranged. Content information is displayed three-dimensionally.
Therefore, the content information is displayed on the screen of the client 2 as if it is floating above the map image MJ, which is an excellent display mode that is visually interesting.

  According to the search result screen display method described in the present embodiment, when information related to content to which position information is added is displayed on the screen in association with a map image, visibility can be improved and visual It is possible to realize an excellent display mode. Specifically, since the content information is displayed so as not to overlap the map image, the map image is not hidden by the display of the content information, and there is no possibility that the map content becomes difficult to recognize. Further, since the map image and the content information are displayed three-dimensionally, it is very interesting visually.

  As mentioned above, although the invention made | formed by this inventor was concretely demonstrated based on embodiment, this invention is not limited to the said embodiment, It can change in the range which does not deviate from the summary.

For example, on the search result screen D2 shown in FIG. 6, the map image may be enlarged / reduced based on the user's operation.
For example, when the user clicks on a point associated with the displayed content, a map image in which this area is enlarged is displayed. Further, for example, when the user operates a mouse wheel, a map image enlarged / reduced in stages is displayed.

FIG. 8 is an explanatory diagram illustrating an example of a screen when a map image is enlarged and displayed based on a user operation. For example, in the state where the search result screen D2 shown in FIG. 6 is displayed, it is a screen example displayed when an operation for selecting a specific area is performed by the user.
As shown in FIG. 8, the visual interest can be enhanced by displaying the enlarged map image MH of Hyogo Prefecture in the sky while maintaining the display of the Japan map image MJ.

In order to realize such a display mode, for example, in FIG. 6, a Japan map image is divided into a plurality of regions (for example, prefecture units) and displayed. When a specific area is clicked, a map image obtained by enlarging this area is controlled to be displayed above the Japan map image.
That is, when the map image is divided into a plurality of regions (for example, prefecture units in the case of a Japanese map image), based on a user operation for enlarging and displaying a specific region in the map image, the original map image An enlarged map of the selected area is formed in the sky space formed in the Z-axis direction (for example, plus (upward) direction) with respect to the ground space on which the map image is drawn while maintaining the display of An image is being drawn.
A display area (display frame) for displaying information related to the content is set in an area that does not overlap any drawing area of the map image and the enlarged map image.

Accordingly, it is possible to confirm which part of the entire map image corresponds to the enlarged map image, and it is possible to improve the visual interest by the display mode in which the corresponding area is raised from the Japan map image.
Further, the enlarged map image displayed in an enlarged manner is also displayed in a plurality of areas (for example, in units of municipalities), and when a specific area is clicked, a map image in which this area is enlarged is displayed further upward. You may be made to do. If a plurality of map images are displayed on the screen, the display on the screen becomes complicated and the visibility may be lowered. Therefore, it is desirable to delete the original map image as appropriate.
Furthermore, when an enlarged map image is displayed, if the animation is displayed so as to emerge from the original map image, the visual effect can be further improved.

  In the above embodiment, the content display area and the corresponding point on the map image are connected by a lead line. However, as shown in FIG. 9, the content display area is formed so as to surround the content display area. The relation between the content and the corresponding point may be expressed by a display mode in which a balloon frame emitted from the corresponding point is displayed in the sky space. At this time, it is desirable to change the display color (display mode) of the balloon frame according to the area (corresponding point) related to the content displayed in the balloon frame.

  Moreover, in the said embodiment, although the display mode of a display frame or a leader line is unified for every content, you may make it unify a display mode for every corresponding point. That is, when there are a plurality of contents related to the same region, the display modes are unified, for example, the content corresponding to the region of East Japan is blue and the content corresponding to the region of West Japan is red. This makes it easy to grasp the relevance between contents corresponding to the same region.

  Furthermore, the display of the content may be erased (not displayed) in response to a user operation (for example, a selection operation) by the display control process. In addition, the display area of other contents may be expanded as the display of contents is erased. As a result, even when the amount of content to be displayed due to content search or the like becomes enormous, the user can delete unnecessary content as appropriate, so that the visibility of the search result screen can be improved.

Further, for example, in the above-described embodiment, the search result screen when the directory search is performed on the portal site has been described. However, the search result screen can also be applied to a search result screen by keyword search.
In addition, the present invention is not limited to a case where a web page is a search target in a portal site, and can be applied to a search service specialized for content of a specific genre. For example, a content search service having location information, such as a restaurant or a facility such as a hospital, can be considered.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
