Motion in industrial products contributes to both functional and aesthetic qualities, and stimulates user curiosity and interest, thereby encouraging the formation of attachment to the product. In this study, we deduced that the optimal prediction error from typical motion leads to interest, and that fluctuations in prediction error arouse curiosity. Using the free energy principle, a unifying principle of the brain, we formulated that fluctuations in prediction error encourage curiosity and decreases in prediction error arouse interest. We also developed a system to generate motion by controlling prediction error, and experimentally confirmed that the evaluation of interest is convex upward with respect to prediction error and that fluctuations in prediction error increase curiosity.
