초록
텔레프리젠스 로봇과 사람의 소통은 텔레프리젠스 로봇을 통한 원격 발신자와 수신자의 소통이라 할 수 있다. 이에 따라, 텔레프리젠스 로봇을 통한 원활한 감정소통을 위해서는 원격 발신자의 실재감이 효과적으로 전달되어야 한다. 이 연구에서는 수신자의 움직임을 모방하여, 동일하게 움직이는 로봇의 움직임을 디자인하고, 수신자의 움직임을 모방하는 로봇과, 움직임이 없는 로봇 두 가지 조건을 사용하여 24명의 피험자를 대상으로 원격 발신자의 실재감에 대해 평가하였다. 실험 분석 결과, 피험자들은 수신자의 움직임을 모방하여 움직이는 로봇과 소통할 때, 아무 움직임이 없는 로봇보다 원격 발신자에게 보다 높은 실재감을 느꼈다. 이는 수신자의 움직임을 모방하는 텔레프리젠스 로봇의 움직임이 수신자와 원격 발신자 간의 감정소통에 효과적임을 알 수 있다.
Abstract
As a telepresence robot is developed for interpersonal communication between a remote sender and a receiver, sending presence of a remote sender to a receiver is an important issue. In order to find effective ways to increase presence, we executed a 2 (mirroring movement: telepresence robot with mirroring movement vs. telepresence robot without movement) within-participants experiment (N=24). In this study, participants observed two videos depicting a receiver interacting with a sender through a telepresence robot with mirror movement of a receiver's actions, and one without any movement. The results showed that participants felt more presence when interacting with a telepresence robot with synchronized movement than a robot without any movement. Implications for design of telepresence robots to increase presence are discussed.
