Abstract
Towards harmony between human and society for the sustainable development of humanity, we had constructed a web site for “Sym-bio Society Formation” as a forum of knowledge sharing and mutual communication. Additionally, towards providing friendly place for dialogue between multigenerational people about various social issues, we have considered a web site using network communication. The character agent was introduced to navigate into a community and to provoke participants’ message. We have conducted the experiment to research the evaluation and effectiveness of the web site with respect to evocation of messages, usefulness of navigation, and so on. In consequense, we have found that the usefulness of the navigator would have relation with the familiarity to the networked community.
