Description

  The present invention relates to an information transmission system and an information transmission method capable of transmitting information between a plurality of users, and more particularly to an information transmission system and an information transmission method for transmitting information based on user location information.

  In recent years, as information networking progresses, an information transmission system capable of transmitting information among a plurality of users has been developed, as represented by an electronic bulletin board or the like. For example, in an electronic bulletin board, multiple users can access a server on the network using an information terminal such as a computer, browse the information on the electronic bulletin board, or write information on the electronic bulletin board. This is a computer system in which messages can be exchanged between persons (for example, Patent Document 1).

  In the information transmission system such as the electronic bulletin board described above, messages can be easily exchanged between a plurality of users, but the information transmitted from the information transmission system is the same regardless of the location information of the users. The same information is transmitted to the user who accesses the electronic bulletin board at the same time regardless of the current position of the user.

  As a computer system for changing information to be transmitted to a user according to the user's location information, an information providing system using a network is disclosed in a guidance service such as a sightseeing spot (for example, Patent Document 2). In the information providing system, the user possesses an information terminal having means for measuring the current position, and the information providing server that provides information to the user is based on the position information transmitted from the information terminal. To users. By using the information providing system, the user can obtain information on the historic sites / famous spots, etc. in real time at historic sites / famous spots, etc. of sightseeing spots.

In addition to the above-described functions, an information providing system capable of storing information (for example, photographic images) created by a user at a historic spot or a famous place in a tourist spot is also disclosed (for example, Patent Document 3). In this information provision system, the user can obtain information on the historical sites / famous places, etc. of the tourist spot in real time, and provide information created by the user, such as photographs or videos. It can be stored in a data center provided in the system.

At present, there is a person who performs an act called “Rakugaki” in order to leave information such as a message in a place where an object is located. Naturally, "Rakugaki" is an illegal act and is not preferable because it detracts from the scenery of the sightseeing spot.

  Furthermore, the second problem is that in the conventional information providing system, the information stored in the information providing system by the user is information personally used by the user as described above. It is a point that information cannot be shared. Even if the user releases the information stored in the information providing system on the personal homepage, it is an action that the user personally performs and cannot be called information sharing.

  A third problem is that in the conventional information providing system, a tourist association or a travel agency or the like sets an object in advance, and the user cannot set the object. The object that the user is interested in varies from user to user. For example, even if you visit the same building, some people are interested in the exterior of the building, while others are interested in the interior (for example, furniture) of the building. It is preferable that the user can set the object in the sense that the information providing system is user-oriented.

[Operation procedure of information transmission system of this embodiment]
From here, the procedure of the information transmission method of this Embodiment is demonstrated in detail, referring a figure. The information transmission method according to the present embodiment includes an information posting step in which an information transmission server (Web server) stores post information posted from an information terminal (mobile phone 10) possessed by a user, and an information transmission server (Web server). ) In the information transmission step of transmitting the post information stored to the user. First, the information transmission process will be described, and then the information posting process will be described.

<Description of information transmission process>
FIG. 9 is a flowchart for explaining the operation procedure of the information transmission process. The information transmission process is a process in which the Web server 20 generates content from the posted information stored in the posted information storage unit 22 and transmits the content to the user.

  The first step (S100) of the information transmission process is a step in which the user starts accessing the information transmission server (Web server 20) using the information terminal (mobile phone 10). The user activates a browser provided in the mobile phone 10 and accesses the Web server 20. Here, information for specifying the server such as the network address or URL of the Web server 20 is stored in the storage unit 14 of the mobile phone 10.

  The next step (S110) is a step in which the mobile phone 10 acquires the current position information and the current movement direction information by using the position information detection means 11 (GPS function). The mobile phone 10 transmits the acquired position information and movement direction information to the Web server 20.

  The next step (S120) is a step of calculating the extraction area based on the position information and movement direction information received by the content generation means 21 provided in the Web server 20. The calculation of the extraction area has been described above.

  In the next step (S130), content is generated from the posting information stored in the posting information database 22 in association with the position information in the extraction area calculated by the content generation means 21, and the content generated in the mobile phone 10 is generated. It is a step to transmit.

  The next step (S140) is a step in which the mobile phone 10 receives the content transmitted from the Web server 20 and displays it on the content display means 13 (display and browser) of the mobile phone 10. The user can browse the content transmitted from the Web server 20 on the content display unit 13 of the mobile phone 10.

  After the process of step S140 ends, the information transmission process ends. In the present embodiment, the position information and the moving direction information are transmitted from the information terminal (mobile phone 10), but only the position information may be transmitted from the information terminal. When only the position information is transmitted, the extraction region is calculated based only on the position information.

  In addition, when the position detection accuracy of the position detection unit 11 of the information terminal is low (for example, the minimum position detection accuracy is 100 meters), it is not necessary to calculate the extraction area when generating the content. When the extraction area is not calculated, the post information used when generating the content is the post information stored in association with the position information transmitted from the information terminal.

<Description of information submission process>
Next, the information posting process will be described. FIG. 10 is a flowchart for explaining the procedure of the information posting process. In the information posting step, the user transmits posted information to the Web server 20 using the information terminal (mobile phone 10), and the Web server 20 posts the received posted information in association with the posted location information. This is a step of storing in the information database 22.

  The first step (S200) of the information posting process is to access the posted information registration means 24 (posted information registration content) of the information transmission server (Web server 20) using the information terminal (mobile phone 10) possessed by the user. It is a step to do.

  The next step (S210) is a step of creating posted information to be transmitted to the Web server 20 using the posted information creating means 12 of the mobile phone 10.

  The next step (220) is a step in which the mobile phone 10 acquires the current position information using the position information detecting means (GPS function).

  The next step (S230) is a step of transmitting the post information created in step S210 and the position information acquired in step S220 to the Web server 20.

  The next step (S240) is a step in which the Web server 20 stores the received post information in the post information database 22 in association with the received position information. When the posted information received by the Web server 20 is stored in the posted information database 22, the attached information of the received posted information is also stored together with the received posted information (when the posted information is object information or level 1 emotion information). Key information is also stored).

  After performing the process of step S240, the information posting process ends. By executing a large number of information posting steps, a large amount of posted information is recorded in the object information database 22 in the Web server 20.

[Description of the effect of the present embodiment]
According to the information transmission system and the information transmission method described so far, the user can virtually leave post information at a point where post information such as a message is desired to be left. That is, a user posts posted information to an information transmission server using an information terminal provided with a position detection unit, and the information transmission server posts the posted information that is posted in association with the location information of the posted point. The post information is stored at a virtual post location.

  Further, the posted information posted by the user can be viewed by all users who have visited in the vicinity of the point where the posted information is posted. That is, when a user visits the vicinity of the posted point, it means that the position information where the posted information is posted is included in the extraction area calculated based on the position information of the user. The post information stored in association with the position information is transmitted to the user. In other words, the posted information is not transmitted to a user who is not near the position where the posted information is posted.

  Furthermore, since the user can post message information (emotional information in the present embodiment) for the theme information (object information in the present embodiment), the message information for the theme information can be exchanged among a plurality of users. . The theme information can be arbitrarily set by the user.

[Description of Other Embodiments]
The embodiments of the present invention described so far are only preferred examples of the present invention. When the principle of the present invention is embodied, various other embodiments can be realized. Other embodiments will be described below.

<Description of another embodiment of information terminal>
In the above-described embodiment, the information terminal owned by the user is the mobile phone 10, but the present invention can also be realized using another information terminal. For example, a mobile computer having a GPS function, a PDA having a GPS function (abbreviation for Personal Digital Assistance), a PHS (abbreviation for Personal Handyphone System), etc., and a computer device capable of network communication can be used as an information terminal Can be used as

  In the above-described embodiment, the GPS is used as the position detection means, but other position detection means 11 that can measure the current position of the user may be used. For example, position detecting means using a PHS base station and position detecting means using an IC tag.

Here, the position detection means using the IC tag means that the user possesses an IC tag storing information for identifying the user, and installs a plurality of IC tag readers / writers connected to the information transmission server at a historic site or the like. The position detection means identifies the user and the user's position information accessed by the information transmission server from the information of the IC tag reader / writer accessed by the user.
<Another embodiment of information transmission server>

  In the above-described embodiment, the information transmission server is the Web server 20, but the information transmission server of the present invention may be any server that operates on the network and transmits information to the information terminal. Further, the network is not limited to the mobile phone network and the Internet shown in the above-described embodiment, but may be a public telephone network, a LAN (abbreviation of Local Area Network), or a network in which various networks are combined.

  Further, although the logical structure of the posted information stored in the posted information storage means 22 is a hierarchical structure, it is desirable that the logical structure is determined according to the actual operation system. This is because, in an actual operation system, various information (for example, a user's mail address) not described in this specification is also stored in the posted information storage unit 22.

  Furthermore, in the above-described embodiment, post information is stored in association with position information. However, post information may be stored in association with other information in addition to position information. For example, post information can be stored in association with position information including altitude information.

  In this case, the user cannot view the posted information unless the posted information is posted at a high level. Further, the information terminal possessed by the user needs to have position information detecting means for measuring position information including altitude information (for example, a mobile phone equipped with a GPS capable of measuring three-dimensional position information). .

  Furthermore, as described above, the present invention can be realized regardless of the shape of the extraction region that is calculated for the transmission information generation means 21 to extract post information. The shape of the extraction region is preferably a fan shape or a circular shape, but may be a quadrangle, a triangle, or a more complicated shape.

  Further, the size of the extraction region (for example, the length of the radius R in FIG. 4) may be a fixed value set in advance, or the user may be able to change the scale of the extraction region (for example, FIG. 4). Then change the length of radius R).

  Furthermore, the transmission information generated by the transmission information generation unit 21 may be generated according to the specifications of the content display unit 13 of the information terminal. For example, when the amount of information that can be displayed by the content display unit 13 of the information terminal is small, the object information may be displayed as text without displaying the object information as a visualization object. In the case of text display, information that lists the file names of the object information stored in the posted information recording means 22 may be displayed.

  In addition, the posted information registration means 24 of the information transmission server described in the above embodiment is only an example. The posted information registration unit 24 may be used as a unit for registering information not described in the embodiment (for example, information such as a user's nickname and email address).
