Display format conversion button 1204 is buttons repeatedly (toggle button) of changed content retrieval process result's display format.The user is by clicking display format conversion button 1204, and the display format pattern is set to one of them of " tabulation is upgraded automatically " and " tabulation is fixing ".In the content information guide look tabulation 1205,, show the title of the content information that from list content, extracts according to the search condition of the content of setting by search condition setup unit 1002.
Meanwhile, the icon (in Figure 12) that shows the geographic position of the content of representing the dependence position corresponding in the map display unit 1001 with the number of circle sign encirclement with content information.In addition, as shown in figure 12, the information that shows in map display unit 1001 and the content information guide look tabulation 1205 is corresponding with number or other mark.In this example, in region of interest ROI1203, there are restaurant A, the C of convenience store, the D of refuelling station, parking lot E.In addition, under the state of Figure 12, when clicking return push-button 1009, can return the search condition of Figure 11 and set picture.
Like this, have a guide look of demonstration owing to will rely on the result for retrieval of the content of position as display list, the position that shows simultaneously the content of the dependence position that retrieves on map is so the user is by the geographic distribution situation of the content visually confirming to retrieve, the actual content of wanting audiovisual of decision.
In addition, compare, under the excessive situation of region of interest ROI1203,, in the map of the ratio that has changed, show region of interest ROI1203 by the ratio of change map with the map during map display unit 1001 shows.Equally, compare, under the too small situation of region of interest ROI1203,, on map, show region of interest ROI1203 with suitable size by the ratio of change map with the map during map display unit 1001 shows.
Figure 13 is illustrated in the content display 104 of present embodiment, and content display 104 moves and the figure of an example of GUI picture when retrieving the content of current place periphery again.In this example, the current location of content display 104 moves to place 1301, as its result, and the content difference of the dependence position that comprises in the region of interest ROI1302.
Specifically, the D of refuelling station has arrived the outside of region of interest ROI1302, and the G of convenience store newly enters among the region of interest ROI1302.In content information guide look tabulation 1205,, make number and the guide look display position in tabulating identical for common restaurant A, the C of convenience store, parking lot E in the result for retrieval (Figure 12) of last time and the result for retrieval this time.In addition, the 3rd the D of refuelling station is replaced with the G of convenience store, the D of refuelling station is moved to the 5th of tabulation.
Like this, in map display unit 1001 and content information guide look tabulation, when showing the content information that comprises among the up-to-date region of interest ROI1302, the history of also preserving content retrieval shows detected before this content information in the lump.
In addition, in map display unit 1001 and content information guide look tabulation 1205, in order to distinguish up-to-date content information and content information in the past clearly, by number or mark difference to the content information distribution.In the example of Figure 12, give the number that surrounds by the circle sign to up-to-date content information, the content information in past is given the number 1304 that surrounds by the quadrilateral sign.
Like this, because difference shows the content information that retrieves in the past clearly, so the user can use content retrieval result in the past neatly on the basis of the renewal situation of having grasped the result for retrieval tabulation.
And then, about the new detected content information that did not contain in the former result for retrieval, show special sign so that it is outstanding.In the example of Figure 13, about the new detected G of convenience store, in content information guide look tabulation, give asterisk and know 1303, in content map display unit 1001, represent to rely on the number of the content of position with dual circle encirclement.
To display packing augmented content information guide look tabulation 1205.The update rule of content information in present embodiment guide look tabulation is assumed to be (1) content information about comprising among two of once preceding and up-to-date result for retrieval, the display position that does not change in the guide look tabulation shows, (2) deletion is included in the previous result for retrieval but is not included in content information in the up-to-date result for retrieval from guide look tabulation, its display line is made as the sky hurdle, (3) will not be included in the previous result for retrieval but the content information that is included in the up-to-date result for retrieval inserts the empty hurdle part of guide look tabulation, under the situation that does not have sky hurdle part, be set forth in guide look tabulation below, (4) will be included in the result for retrieval in the past but not be included in the bottom (end) that content information in the up-to-date result for retrieval is attached to the guide look tabulation.
Like this, in map display unit 1001 and content information guide look tabulation 1205, by distinguishing content information that comprises among the up-to-date region of interest ROI and the content information that retrieves in the past clearly, and show simultaneously, make the content retrieval result be easy to visual identity, the convenience of content retrieval component improves.In addition, not only publish up-to-date content retrieval result, and in the past content retrieval result is published in tabulation in result for retrieval, thus the user on the basis of the renewal situation of having grasped the result for retrieval tabulation, content retrieval result in the past can apply in a flexible way.
The user after the content of finding to wish, clicks display format change button 1204 with reference to the content retrieval result as Figure 13.So GUI picture 1000 is updated as shown in figure 14, the display format pattern that shows in the display format change button 1204 becomes " tabulation is fixing ", utilizes cursor movable button 1007, can select a content information from content information guide look tabulation 1205.
In addition, because content displayed information is established correspondence in the icon of the position of the content of the dependence position that shows on the expression map display unit 1001 and the content information guide look tabulation 1205, also can chosen content information by the icon of clicking on the map.
Figure 15 is illustrated in the content display 104 of present embodiment, and the user utilizes cursor movable button 1007 to select the figure of situation of the 4th parking lot E1502 from content information guide look tabulation 1205.When becoming " tabulation is fixing " pattern, even content display 104 moves, content information guide look tabulation is not upgraded automatically yet.In the map display unit 1001, when transferring to " tabulation is fixing " pattern, show fixing region of interest ROI1302, meanwhile also show the current place 1501 of the content display 104 in moving.
Like this,, can stop the renewal of contents list temporarily, and on map, proceed the display update of up-to-date current location information during the user with reference to display list.Thus, with the content retrieval result's of a certain fixing position demonstration simultaneously, shows up-to-date terminal positional information, thereby the grasp that the content of the dependence position of wishing and the geographic position between the content display concern becomes easy.In addition, in Figure 15, also can change the Show Color of user, perhaps make the icon flicker by the number 1502 pairing icons of in map display unit 1001, pointing out of the content information of cursor movable button 1007 selections.
Like this, can improve the visual identity raising of the icon corresponding with the content information of having selected.In addition, be present under the situation of outside of the map of map display unit 1001 showing in the position of the contents of selecting from content information guide look tabulation 1205, the map of map display unit 1001 is drawn once more, the content of having selected with demonstration.
Under the state that the picture of Figure 15 shows, when user click display format change button 1204 or return push-button 1009, return the state of Figure 13, move simultaneously with the position of content display 104, carry out the content retrieval of current place periphery termly.In addition, during user click decision button 1008, the GUI picture is transferred to the state of Figure 16.
Figure 16 is the figure of demonstration example of the GUI picture in the content display 104 of expression present embodiment.In Figure 16, GUI picture 1000 has summary info display unit 1602.Show the content information that is transformed to the form that can in browser, show in this summary info display unit 1602.In this example, the network location information (URI) and having under the situation of content information of summary info (among Figure 16 for cost information) of content of content of having recorded and narrated title, residence, telephone number and the dependence position of content in list content describes.
Content display 104 generates the content of the form in the browser that can be presented at according to the content information of having been specified by the user in Figure 15, and the content that will generate is presented in the summary info display unit 1602 as illustrated in fig. 16.Like this, when displaying contents information, the user just can judge whether to obtain practically/content of this dependence position of audiovisual after the summary of having grasped the content that relies on the position.
On the other hand, in the map display unit 1001 of Figure 16, show the content of region of interest ROI1302 when carrying out up-to-date content retrieval, the dependence position corresponding with content information in 1602 demonstrations of summary info display unit position, content display 104 current location place 1501, be the region of interest ROI1601 at center with place 1501.Here, on map, show with place 1501 to be that the region of interest ROI1601 at center is in order to make the user can easily confirm the content of the dependence position that summary info is represented and the geographic position relation of content display 104.
For example, the user confirm summary info during the result that moved of content display 104, when the content that becomes the dependence position that summary info represents has been positioned at the situation of distant location of content display 104, by reference map display unit 1001, can detect this situation by the user, and as required the content of current place periphery be retrieved again.
In addition, under the state of Figure 16, during user click return push-button 1009, return the state of Figure 15, can from content information guide look tabulation, reselect content information.In addition, under the state of Figure 16, during user click decision button 1008, GUI picture 1000 is transferred to state shown in Figure 17.
Figure 17 is the figure of demonstration example of the GUI picture in the content display 104 of expression present embodiment.Here, suppose the decision button 1008 among user click Figure 16, GUI picture 1000 is transferred to the state of Figure 17.
The GUI picture 1000 of Figure 17 has URL display unit 1701 and content display unit 1702.The URL that records and narrates in the content information that explicit user is selected in the URL display unit 1701 shows the content of the dependence position corresponding with the URL of demonstration in the URL display unit 1701 in the content display unit 1702.In addition, GUI picture 1000 has save button 1703.
This save button 1703 is used for preserving the URL or the content information of the content of the dependence position that content display unit 1702 shows.For example, useful if the user is judged as the content of the content display unit 1702 dependence position in showing, the possibility height of audiovisual is then clicked save button 1703 information of carrying out and is preserved once more.When saved content information can both be presented in the summary info display unit 1602 of Figure 16, if click the decision button 1008 of Figure 16, then as shown in figure 17, the content of the URI that expression extracts from content information is shown.
Then, Figure 18 and Figure 19 represent the search condition as content, the example of the radius of appointment region of interest ROI1101 and the retrieval number of content.Figure 18 and Figure 19 are the figure of demonstration example of the GUI picture in the content display 104 of expression present embodiment.Suppose under the situation of the radius of not setting region of interest ROI, set the radius predesignated.
Figure 19 is that expression is carried out retrieval process based on the condition of appointment in 18 to list content and illustration content retrieval result's example on picture.In this example, in map display unit 1001, show two region of interest ROI1902 and 1903.Region of interest ROI1902 shown in the dotted line is the border circular areas of 200 meters of the radiuses set of user.In this example, in this border circular areas, only contain four contents.
Like this under the situation of the retrieval number of the number of the content that comprises among the region of interest ROI1902 discontented user content of having specified, content display 104 adjusts radius of a circles and sets region of interest ROI1903 again, so that approach the retrieval number of the content that the user specified.
Otherwise, in the region of interest ROI (not shown) that the user has specified, containing under the situation of content of the content retrieval number of having specified above the user, content display 104 reduces the radius of region of interest ROI, so that near the retrieval number of the content of user's appointment.Like this, when the radius of adjusting region of interest ROI was set in the content display 104 with the retrieval number of the content that satisfies the user and specified, the convenience of content retrieval improved.
Like this, under the situation of having specified the retrieval number as the content retrieval condition, dynamically adjust the size of search domain, the content retrieved result for retrieval of appointment has been satisfied in output.Thus, the burden for users in the time of can alleviating content retrieval.
Figure 20 and Figure 21 are the figure of the demonstration example in the expression portable phone terminal of the present invention.Figure 20 represents the situation same with Figure 12.Expression is the region of interest ROI2003 at center with user 2002 current location on the map 2001.But, because the picture 2011 of the carried terminal held of user is little, therefore displayed map 2001 and only show result 2012 after the content in the searching interest district ROI2003 not.
Figure 21 represents the situation after user 2002 moves.As shown in figure 21, the user moves to 2102 with current location, and region of interest ROI also moves to 2103 simultaneously.Therefore, as content displayed in the carried terminal picture 2111, newly add the G of convenience store (2114), the D of refuelling station (2115) is displayed on the end as extraneous information.This display packing and Figure 13 are same.Like this, while the portable phone terminal also moves the content around can retrieving.In addition, in the example of Figure 21, the content that has been updated by change and the display packing of extraneous content and show easily with understanding.Thus, even content changes along with moving, also can easily discern difference, the extraneous content of content that has been updated and the content that is not updated.
In addition, in the present embodiment, the search domain of content is made as border circular areas, but the search domain of content also can be a shape arbitrarily.For example, can with the map display unit 1001 of content display 104 in the rectangular area of the identical size of map that shows as the content retrieval zone, perhaps also can be on the direct of travel of content display 104, expand fan-shaped.
In addition, in the present embodiment, adopt content broadcasting server 101 or 102 pairs of content displays of the content communication server to be equipped with the list content of Fig. 7 in 104 minutes for example, general 103 pairs of content displays of Web server 104 distribute the mode of the content that relies on the position, but also can distribute a plurality of content informations to replace contents list.Content display 104 replaces retrieval of content information from contents list, all the elements information that receives is managed, and from this management information retrieval of content information.Thus, even the ISP only also can obtain same result by content information not from being to generate the content information of example and list content is provided with Fig. 5 or Fig. 6.
In addition, the content that relies on the position also can be distributed and be replaced being distributed by general Web server 103 by content broadcasting server 101.Content display 104 will based on the content information that the retrieval by list content or content information obtains, be obtained content from storage unit 206 from the content stores of the dependence position that content broadcasting server 101 receives storage unit 206.Thus, under the situation of the content that content information or dependence position only are provided from content broadcasting server 101, also can obtain same effect.
This instructions is willing to that based on the spy of application on June 7th, 2004 spy of 2004-168209 and application on June 2nd, 2005 is willing to 2005-163088.Its content all is contained in this.
