Inconsistency of personality evaluation caused by appearance gap in robotic telecommunication

Abstract

Compared with other communication media such as cellphones and video chat, teleoperated robots have a physical existence which increases the feeling of copresence. However, the appearance of a teleoperated robot is always the same regardless of the characteristics of its operator. Since people can determine their partner’s personality from his/her appearance, a teleoperated robot’s appearance might construct a personality that confuses the user. Our research focuses on establishing what kind of appearance of the telecommunication media could prevent confusion and increase the feeling of copresence. In this study, we compare the appearance of three types of communication media (nonhuman-like robot, human-like robot, and video chat with a projection of the speaker). The result shows that, in the case of the human-like robot, the consistency of the personality judgment is better than in the case of the nonhuman-like robot. Also, we found that teleoperated robots transmit a more appropriate context-based atmosphere, while the video chat transmits more nonverbal information, such as facial expressions.
