Discussions on human-robot interactions abound in the fields of human-agent interaction and human-robot interaction. Although studies on communication through conversations and physical actions have been conducted, many of these studies focus on robot gaze while neglecting human gaze. In this study, we developed Pocketable-Bones, a mobile robot that can move with the human gaze in mind. This robot can fit in a breast pocket and follows and turns in the same direction a person faces. Notably, we have been investigating the realization of joint gazing in which two persons share interests and concerns through gazing. This study’s experiment results showed that Pocketable-Bones’ gazing behaviors satisfied the components of self-determination theory in well-being, notably autonomy, competence, and relationship.
