Abstract

When collecting opinions to decide roles, majority votes after discussions are often used. Therefore, an environment that smoothly leads to reasonable and satisfactory conclusions in necessary. In this paper, the authors propose a consensus development support system that visualizes opinion input histories. Users input their opinions by moving images on the interface with a mouse, and input histories are replayed as animation. Users can input not only local but global opinions by seeing other user inputs. Such input histories might change other users' minds by visualizing minority opinions. In this study, the targets of the system are role-sharing problems ordinary discussed in small groups of four to eight acquaintances. Based on the experimental results, the system effectively realized opinion convergence and acceptable conclusions.
