Applying Rough Set to Analyze Psychological Effect of Mascot Character Design

摘要

In this study, we investigated psychological effects of character design for gaining good evaluation, and tried to apply rough set analysis to design of mascot characters. In Studies 1 and 2, we examined how the shapes of the parts constituting mascot characters influenced their impression and how the impression of a character varied the evaluation. In Study 1, using 12 popular mascot characters, we examined which part shapes of mascot characters affected good evaluation. In Study 2, we made new mascot characters which had more various combinations of part shapes than in Study 1. The results of Studies 1 and 2 indicated that high “lightweightness” impressions increased character's evaluations. Therefore, we extracted the combinations of the shapes which increased “lightweightness” impression. The results suggested that the part shapes of eyes consisting of white and black parts may be important for getting good evaluation on mascot characters.
