In this paper, we experimentally examined whether facial expression changes in teleoperated androids can affect and regulate operators' emotion, based on the facial feedback theory of emotion and the body ownership transfer phenomena to teleoperated android robot. We created a conversational situation where participants felt anger and, during the conversation, the android's facial expressions were automatically changed. We examined whether such changes affected the operator emotions. As a result, we found that when one can well operate the robot, the operator's emotional states are affected by the android's facial expression changes.
