An attempt to present group-activated communication with the Ebbinghaus illusion for idea generation

Abstract

As the saying goes, “Two minds are better than one”, group communication can generate more ideas than individual thinking. To generate good ideas, a good relationship in a group as well as an activated and smooth interaction are essential during group communication. Previous research proposed many idea generation systems that are intervened directly in the idea during group communication. However, an approach to indirectly support idea generation by enhancing group communication has not been sufficiently examined. In this study, we constructed a system that visually presents the activation level in group communication. This system is projected the Ebbinghaus illusion on a desk and designed to change it based on the activation level that estimated using our group-activated communication model. The effectiveness of the system demonstrated by sensory evaluations.
