Paper Abstract:	Today, there is a variety of Internet services related to social web like MySpace. In these services, people with similar interests, tastes and attributes, who are banded together as a group called "Community," engage in a type of communication (exchanging or providing information) found in a social network (the so-called "Circle of Friends") in the real world. At the same time, the Internet services for mobile phones are rapidly increasing. In the recent years, almost all mobile phones sold in Japan come with a camera built-in, and other functions such as the GPS (Global Positioning System) function are becoming popular. This study investigates a new style of communication with a mobile phone camera and the GPS functions. Specifically, the study is based on the assumption that a community will be formed with people sharing location and time even though they do not know each other in the real world. In addition, this study has developed an interactive communication game called PICTORI (PICture shiriTORI), which creates a community to play in – just like the real world in which close friends play. In this game, with the GPS functions on the mobile phone, users send their present locations to the system, and only when the users stay within a specified range, they are allowed to participate in the shiritori game. In other words, it is a game that allows fellow users in nearby locations to play shiritori with a feeling of friendship even though they are all strangers to one another. From the verification experiment, an active communication, which takes place even among users who are strangers, has been verified.
