In this paper, we discuss indirect communication between human and a robot through physiological phenomena, which consist of breathing, heartbeats and the body temperature, and which express robot’s emotion. We set a situation with joint attention between the robot and user to an emotional photo and video contents, and evaluated whether both the user’s emotional response to the content and the user’s impression on relationship between the user and the robot were changed by the physiological expressions of the robot. The results suggest that the physiological expression of the robot would make the user’s own emotion in the experience more excited or suppressed, and that the robot’s expression would increase impressions of closeness and sensitivity.
