Recently in Japan, many workshops for community improvement have been held at an active pace. The main feature of these workshops is that their contents are specialized. For this reason, both communication and understanding among participants in such workshops are difficult to achieve and therefore require much time and effort. In particular, at workshops for the discussion of the future image of a town, it is very important that participants understand and share the future image. To address this issue, we developed a VR (virtual reality) system for sharing a future image and proposed a practical use method for workshops. Furthermore, we verified the effectiveness of this system at actual workshops. As a result, we clarified that VR is useful in the three areas of stimulating communication, speeding up the decision-making process, and converting ideas.
