C² AT²HUB: Long-term Characterization of Robots based on Human Child's Personality Development

摘要

Inadequate variety of personalities for communication robots may cause unnatural interaction with them and reduction in attachment. This paper proposes C² AT² HUB, where communication robots are characterized by changing tendency of affect transition based on long-term interaction with users. In C² AT² HUB, robots' affect is defined as two types; “interpersonal affect” and “emotions”, and transition of each type of affect is adjusted by history of users' actions to robots in order to characterize robots gradually. Evaluation experiment revealed our approach characterizes robots naturally and improves impression of robots.
