2. Description of the Related Art In recent years, with the development of networks such as the Internet and the widespread use of personal computers, it has become common to exchange electronic mail and the like via the networks. With the spread of mobile phones, it has become common to exchange e-mails using mobile phones. Information exchange by e-mail or mobile phone is basically information exchange between individuals, and information is exchanged by designating a specific individual.

On the other hand, in the area of knowledge management, an information sharing support system has been proposed which supports sharing of information and knowledge held by individuals belonging to organizations such as companies. For example, Japanese Patent Laid-Open No. 2001-357064 discloses a system that supports information sharing by registering and disclosing the know-how of individuals. When the user searches the registered know-how, the desired knowledge may not be obtained. At this time, the system is characterized in that it enables direct interaction with another user who has registered related know-how.

Further, Japanese Patent Application No. 2000-333971 discloses an information management device for managing a message exchanged by an individual on an electronic bulletin board or a mailing list and an attached material or a document in association with each other. Currently, exchange of e-mail messages often involves the exchange of important knowledge. For example, in product development etc., exchange information about defects that occurred with e-mail,
Problems are solved. When interacting via email, the final conclusion remains only in the head of the individual participating in the interaction, or in the email of the individual. Therefore, the system is characterized in that important knowledge of e-mail exchange is left in the form of a document for easy reuse and stored in association with the e-mail exchange.

[0005] These information sharing systems are configured by the framework of the World Wide Web, and allow a Web browser to access a server of the information sharing system in which information is registered via an intranet or the Internet. There are many things to do.

[0006] On the other hand, a system has been devised for providing information and searching information using position information. For example, GPS
Mobile phones with (global positioning system),
A service using information corresponding to a position is also provided in a mobile device having a unit for acquiring the position information. For example, it is a service that provides map information from the position of the user to the position of the nearest station.

Japanese Patent No. 3234083 (P323408
In 3), there is a means for detecting environmental information such as ambient noise and status information such as position information, the acquired information and status information are stored in association with each other, and after that, status information associated with the information is stored. A system is shown that uses for searching. For example, it is possible to perform a search based on the situation in which the information acquired in the past was acquired, such as “searching for an advertisement seen on the train that I rode yesterday”.

The public information registered by an individual and the information to be exchanged are mostly information depending on the place and time. For example, a message board installed in a station or the like, which has been conventionally handwritten, can be said to be a medium for exchanging information specified at a certain place by a physical means such as a blackboard or a whiteboard. Since this type of message board is set up so that the people waiting for it can exchange information with each other, the information to be exchanged is valid only at that place, and when such information is disclosed to the general public, it becomes valuable. There is no.

Registered information retrieval has not been possible by conventional non-electronic and physical means such as a blackboard and a whiteboard. Further, in the conventional information sharing system, general information can be shared and exchanged regardless of location or time, but it does not provide a function of exchanging information depending on location or time. Further, the mobile device having the means for acquiring the position information only provides or searches the information according to the position information, and does not share the information between the users.

[0010]

As described above, in the conventional information sharing system, general information can be shared and exchanged regardless of location or time, but information depending on location or time is available. There is a problem that a mobile device that does not have a function for exchanging information and has a means for acquiring position information only provides or searches information according to the position information and does not share information between users. there were.

Therefore, the present invention provides an information sharing system and an information sharing method capable of exchanging information depending on the place and time and enabling retrieval and provision of information according to position information. The purpose is to
