Next, a display example of a map or the like displayed by the map display terminal 4 based on the map display process of FIG. 7 will be specifically described with reference to FIGS. 8 to 13.

FIG. 8 is a first display example of the map that the map display terminal 4 first displays on the display in step S202 of FIG. 7. In the example of FIG. 8, the map display terminal 4 displays trees 51 to 54 on a map showing the vicinity of the current position and the like based on the display information S3 received from the server device 1.

In the example of FIG. 8, the map display terminal 4 displays trees 51 to 54 based on the latitude and longitude information indicated by the tree display information included in the display information S3, and displays the sizes of the trees 51 to 54, respectively. It is decided based on the number of posts belonging to the tree. Specifically, the map display terminal 4 displays the tree 51 having 10 or less posts in the smallest size, and the tree 52 having 11 or more and 100 or less posts in the next smallest size, and 101 posts. Trees 53 having 1000 or more items are displayed in the second largest size, and trees 54 having 1001 items or more are displayed in the largest size. As described above, preferably, the map display terminal 4 may increase the size of the displayed tree stepwise or continuously as the number of posts of each tree increases.

FIG. 9 is a second display example of the map that the map display terminal 4 first displays on the display in step S202 of FIG. 7. In the example of FIG. 9, as compared with the example of FIG. 8, since the place where the posting song registration request is made by the posting terminal 3 is widespread, the area corresponding to the place where the posting song registration request is made is wide. many. Therefore, in the example of FIG. 9, more trees are displayed than in FIG. Even in this case, as in the example of FIG. 8, the map display terminal 4 is an area corresponding to the place where the registration request of the posted song is requested based on the latitude and longitude indicated by the tree display information included in the display information S3. A tree is displayed for each tree, and the size of each tree is determined based on the number of posts belonging to each tree.

FIG. 10 is a display example of the display of the map display terminal 4 when the tree 53 becomes active (that is, selectable state) in the example of FIG. When the map display terminal 4 detects mouse over or the like on the display area of an arbitrary tree to be displayed on the map, the map display terminal 4 highlights the tree and activates it. In the example of FIG. 10, the map display terminal 4 displays the activated tree 53 in a color different from that of the other trees 51 to 52 and 54.

FIG. 11 is a display example of the display of the map display terminal 4 when there is an input for selecting the activated tree 53. In this case, the map display terminal 4 extracts the post information belonging to the tree 53 from the display information S3, and displays a branch that classifies each post based on the post date and time information included in each of the extracted post information. Specifically, in FIG. 11, the map display terminal 4 has five branches 60 to 64 for classifying the posting date and time every 10 years, and eight branches for further classifying the branches 60 to 64 every five years. 70A to 74B are displayed. Then, the user of the map display terminal 4 selects any of the branches 70A to 74B corresponding to the age group in which he / she is most interested by the input unit 42. In the example of FIG. 11, the branch 74A corresponding to the posting year from 2010 to 2014 is activated by mouse over or the like. In the above example, when there is an input to select the active tree, the display as shown in FIG. 11 is performed. For example, by touching the display area of the tree on the display screens of FIGS. 8 and 9. , The display as shown in FIG. 11 may be performed.

FIG. 12 is a display example of the display of the map display terminal 4 after the branch 74A of FIG. 11 is selected. In the example of FIG. 12, the map display terminal 4 displays the branch 74A selected by the user input in detail.

Specifically, since the posting year of the posted song classified into 2010-2014 is either 2013 or 2014, the map display terminal 4 has the branch 85 corresponding to 2013 and the branch 85. The branch 86 corresponding to 2014 is displayed as a branch of the branch 74A. Further, since the posting month of the posted song whose posting year is classified as 2013 is either August or September, the map display terminal 4 corresponds to the branch 95A corresponding to August and September. The branch 95B and the branch 95B are displayed as a branch of the branch 85. Similarly, the map display terminal 4 has branches 96A to 96D corresponding to January to April because the posting month of the posted song whose posting year is classified as 2014 is one of January to April. , Is displayed as a branch of branch 86.

Further, in the example of FIG. 12, the leaf 40 is selectably displayed for each post information whose posting date and time match in the year and month corresponding to the most subdivided branches 95A, 95B, 96A to 96D. In the example of FIG. 12, the leaf 40A attached to the branch in August 2013 is activated by mouse over or the like. Then, when the user selects an arbitrary leaf 40 by the input unit 42, the map display terminal 4 extracts the post information corresponding to the selected leaf 40 and displays the post information based on the extracted post information.

FIG. 13 is a display example of the post display window 20 displayed on the display by the map display terminal 4 based on the post information corresponding to the leaf 40A when the leaf 40A is selected. In the example of FIG. 13, the map display terminal 4 has a play button 21, a title 22, an artist name 23, a user name 24, a post comment 25, a post date and time 26, and an image 27 on the post display window 20. Is displayed. By touching the display area of the leaf 40, the display as shown in FIG. 13 may be performed.

Here, the play button 21 is a button for playing the posted song indicated by the posted information corresponding to the leaf 40A, and when the map display terminal 4 detects that the play button 21 is pressed, it is included in the target posted information. By transmitting the acquisition request of the reproduction data S4 for which the posted song ID is specified to the server device 1, the reproduction data S4 of the corresponding posted song is acquired and the posted song is reproduced. Further, the map display terminal 4 displays the title and artist name of the corresponding posted song as the title 22 and the ardist name 23. Further, the map display terminal 4 uses the user name 24 as the user name based on the user information included in the posted information corresponding to the leaf 40A, that is, the user name of the posting terminal 3 that has transmitted the upload information S1 regarding the corresponding posted song. it's shown. Further, the map display terminal 4 displays the post comment included in the post information corresponding to the leaf 40A as the post comment 25. Further, the map display terminal 4 displays the posting date / time 26 based on the posting date / time information included in the corresponding posting information. Further, the image 27 shows an image of the CD jacket of the corresponding posted song received by the map display terminal 4 from the server device 1.

In this way, the map display terminal 4 can preferably accept the reproduction of the posted song by the play button 21, and can preferably make the user recognize the posted comment of the poster attached to the posted song. Here, in the posted comment 25, the impression of the song and the feeling for the posted point are described. Therefore, the user of the map display terminal 4 can suitably share the impressions and feelings about the song heard by the poster at a specific point with the poster. In particular, when the map display terminal 4 displays a map around the current position, and the posted song is played and the posted comment is displayed on the leaf 40 belonging to the tree around the current position, the user of the map display terminal 4 uses the same space. It is possible for the visiting contributor to appropriately share the music listened to in the space and the feelings at that time.

In addition, in FIGS. 11 to 13, the selected tree 53 was branched based on the posting date and time, but the mode of branching is not limited to this. Instead, the map display terminal 4 sets the tree 53 by the genre or release date of the posted song indicated by the posted information belonging to the tree 53, or the classification of the posted comment indicated by the classification information included in each posted information. The branches of the tree 53 may be displayed for each. In another example, the map display terminal 4 may branch and display the tree 53 based on the user information (for example, gender or age or age) included in the posted information belonging to the tree 53. In yet another example, the map display terminal 4 may display branches on the tree 53 for each of the above-mentioned classification criteria. That is, instead of the branches 60 to 64 shown in FIG. 11 which are directly connected to the trunk of the tree 53, the map display terminal 4 branches according to the posting date and time, branches according to the genre of the posted song, and each classification of the posted comment. Branches are provided for each classification standard such as branches that branch to. In this case, the posted information belonging to the tree 53 is classified according to the classification criteria of the branches directly connected to the trunk of the tree 53, and displayed as leaves on the branches of each branch.

It should be noted that these display changes may be made by input instructing the change by the user. For example, when the display is branched based on the posting date and time, the display may be changed by inputting the user to instruct the display to be branched based on the genre of the posted song. The same applies to other examples.

[Modification example]
Hereinafter, each modification of the embodiment will be described. In addition, each of these modified examples may be applied in combination to the above-described embodiment.

(Modification example 1)
In the map display example shown in FIGS. 8 to 10, the map display terminal 4 determines the display mode (display size in FIG. 8) of each tree according to the number of posts. Instead of or in addition to this, the map display terminal 4 is classified according to various criteria such as the attribute of the posted information belonging to each tree, that is, the genre of the corresponding posted song, the posted date and time, the type of posted comment, and the like. The display mode of each tree may be determined based on the tendency of each type.

For example, when the map display terminal 4 determines the type of tree based on the tendency of the posting month indicated by the posting information belonging to the tree, the map display terminal 4 displays the tree with a lot of posting information whose posting month is August by palm trees and posts. A tree with a lot of posted information whose month is December is displayed by a palm tree. In this way, the map display terminal 4 may change the type of the tree according to the posting month, which is the largest for each tree. Further, when the map display terminal 4 determines the type of tree based on the tendency of the genre of the posted song, for example, a tree having many posted songs belonging to rock is displayed as a palm tree. In this way, the map display terminal 4 may change the type of the tree according to the genre of the posted song, which is the most frequently posted song for each tree.

Further, the map display terminal 4 may change the display mode of each tree according to the degree of attention of the posted song belonging to each tree.

For example, the map display terminal 4 acquires the number of times the posted song belonging to the tree has been played for each tree, and determines the size, type, color, etc. of the tree according to the number of times the tree has been played. In this case, the server device 1 stores, for example, the number of times each posted song is played (that is, the number of requests for the playback data S4) included in the posted information registered in the posted information DB 132.

In another example, the map display terminal 4 acquires the number of sympathies for the posted songs belonging to the tree for each tree, and determines the size, type, color, etc. of the tree according to the number of sympathies. In this case, for example, in the display example of the post display window 20 of FIG. 13, the map display terminal 4 further displays an sympathy button to be pressed when sympathizing, and sympathizing when the sympathy button is pressed. Notify the server device 1 to that effect. Then, the server device 1 stores the cumulative number of times (that is, the number of sympathies) notified that there is sympathy for each posted song in the posted information registered in the posted information DB 132.

(Modification 2)
The server device 1 may select the posted information to be included in the display information S3 based on the user information of the map display terminal 4 or the time of transmission of the display information S3.

For example, the server device 1 posts the user-specified information when the upload information S1 includes information (also referred to as "user-specified information") indicating a user ID or the like indicating a user who is permitted to view the posted song. It is included in the information and registered in the posted information DB 132. Then, when the server device 1 receives the range designation information S2, the server device 1 requests the map display terminal 4 for a user ID or the like, and among the posted information belonging to the tree corresponding to the area indicated by the range designation information S2, the user designation Only the posted information that matches the user indicated by the information and the user of the map display terminal 4 is extracted and included in the display information S3.

In another example, the server device 1 uses the upload information S1 transmitted by the above-mentioned posting terminal 3 only to the map display terminal 4 used by the user whose age matches the age of the user of the posting terminal 3 who is the poster. Post information based on the above may be included in the display information S3 and transmitted. In yet another example, the server device 1 records the posting information in which the posting date and time matching the current season and time zone is recorded among the posting information belonging to the tree corresponding to the area indicated by the range designation information S2. It may be extracted from DB 132 and included in the display information S3.

(Modification example 3)
The map display terminal 4 may display a tree on the map only when displaying a map around the current position.

In this case, the map display terminal 4 is, for example, a navigation device for vehicles or pedestrians, and recognizes the current position and displays a map around the current position based on the output of a GPS receiver or the like (not shown). At this time, the map display terminal 4 does not display the tree when displaying a map other than the vicinity of the current position by scrolling the screen or the like. For example, in this case, the map display terminal 4 does not send the range designation information S2 to the server device 1, so that the display information S3 for displaying a tree or the like is not received from the server device 1.

As described above, in the present modification, the map display terminal 4 displays only the trees associated with the area around the current position on the map, and further displays the post display window 20 and the like shown in FIG. 13 according to the user operation. Display and play the selected posted song. As a result, the music listened to in the space and the feelings at that time can be preferably shared among the users who share the same space.

(Modification example 4)
When the current position passes near the tree displayed on the map, the map display terminal 4 may automatically play any posted song belonging to the tree.

In this case, for example, the map display terminal 4 determines whether or not a tree exists within a predetermined distance from the current position, and if it determines that the tree exists, the posted song belonging to the tree is based on a predetermined standard. Select and play automatically. In this case, for example, the map display terminal 4 selects and automatically plays the posted song whose posting date and time is closest to the current date and time. At this time, preferably, the map display terminal 4 automatically displays the post display window 20 of FIG. 13 corresponding to the posted song being played so that the user can simultaneously recognize the posted comment or the like for the posted song. good.

(Modification 5)
The map display terminal 4 may further execute the purchase procedure of the reproduced posted song by communicating with the server device 1.

In this case, for example, the map display terminal 4 further displays a purchase button or the like for starting the purchase procedure on the post display window 20, and when the purchase button is pressed, the post display window 20 displays the button. A purchase request for the music being played is transmitted to the server device 1. Then, after executing the payment process or the like, the map display terminal 4 downloads the reproduction data of the target music from the server device 1 and stores it in the storage unit 33. Before the purchase, the server device 1 may transmit a part of the reproduction data such as the beginning of the posted song to the map display terminal 4 as the reproduction data S4. In this case, the map display terminal 4 can play only a part of the posted song selected by the user before purchasing the posted song.

(Modification 6)
In the display example of FIG. 12, the map display terminal 4 may display an object having another shape such as a strip or a fruit corresponding to each corresponding posted song instead of the leaf 40. For example, when the map display terminal 4 displays strips instead of the leaves 40, the posted comments, the classification of the posted comments, the titles of the posted songs, and the like may be displayed on each strip.

Further, in the display examples of FIGS. 8 to 12, an object having another shape may be displayed instead of the tree.

(Modification 7)
The server device 1 may be composed of a plurality of servers. For example, the server device 1 has a music DB 130, a server that distributes playback data S4, a server that manages the tree management DB 131, and receives upload information S1 from the posting terminal 3 to update the posting information DB 132. It may also be composed of a server that generates display information S3. In this case, each server device 1 connects to the network 2 and exchanges information necessary for executing the pre-assigned process with the other server device 1.

(Modification 8)
Further, the upload information S1 in FIG. 4 does not necessarily include the music and the comment. For example, the song may not be uploaded and the comment may be uploaded and vice versa. In addition, other contents such as videos and photographs may be used instead of the music.
