Modeling of Stress/Interest State Controlling in Robot-Child Play Situation

When we interact with other person, we need a knowledge on other's mind and consult it to decide action of our self. We call the knowledge Model of Other, MoO. To realize a cognitive architecture to interact with human, MoO must be embedded and used in a decision making process. But to design MoO, we must know how human interact in real world in MoO view because we aim a practical human interaction task. So, in this paper, we conducted a child-robot play experiment and analyzed human behavior. From the result, we construct a model of emotion level mental status leading that may be a possible leading concept of human-agent interaction design.
