Can a Robot's Touches Express the Feeling of Kawaii toward an Object?

摘要

Kawaii, a Japanese word that means "cute," is an essential design concept in consumer and pop culture in Japan. In this study, we focused on a situation where a social robot describes an object during an information-providing task, which is commonly required for social robots in daily environments. Since past studies reported kawaii feelings are associated with a motivation to approach a target, our robot expressed feelings of kawaii to objects touch behaviors. We also focused on whether touch behaviors that emphasize style increase the feeling of kawaii of the touched object, following a phenomenon where people strongly touch a target when they overwhelmingly feel positive emotion: cute aggression. Our experimental results showed the effectiveness of touch behaviors to express the feelings of kawaii from the robot toward objects and to increase the participants' feelings of kawaii toward the object. We identified fewer effects from the participants to the robot. The emphasized motion style did not show any significant effects for the kawaii feelings.
