인간-컴퓨터 상호작용 기술을 이용한 인간-로봇 상호작용시 정보처리 촉진에 관한 연구

Abstract

Recent human-robot interaction studies have suggested that a humanoid robot has great potential for social cognition research. However, we’re not aware of any study on social information processing of human-robot interaction. To address this issue, we used two types of social interaction tasks (initiating and responding joint attention tasks) and two types of interaction partners (robot and human partners). Distinguishing these types of joint attention (JA) is important because they are thought to reflect unique but common constellations of processes in human social cognition and social learning. Thirty-seven participants were recruited (Study 1: 20 participants, Study 2: 17 participants) for the current study, and they conducted picture recognition social information processing task with the robot or human partners. The results of Study 1 suggested that participants who interacted with a humanoid robot showed better recognition memory performance in the initiating JA condition than in the responding JA condition. The results of Study 2 suggested that the human-human and human-robot interactions showed similar levels and patterns in recognition memory. We discuss the implications of our results for the utility of humanoid robots in social cognition studies and future research questions on human-robot interaction.
