There is much difference among participants in discussion, in that they handle the knowledge on techniques and expertise, local knowledge, and the way of conducting discussion. The fact can be clearly proved by observing the process of discussion by residents to argue and make some decisions on some regional issue. In this paper, we have an experiment which the participants discuss a cost allocation problem on investment for disaster prevention communication equipment at a supposed area that they reside in. We visualize and analyze the discussion process to insist on opinions each other, to share knowledge, and to build the consensus in the end. The analysis derives essences for facilitating and smoothing such discussion.
