소셜 로봇의 눈동자 움직임을 통한 인간-로봇의 감정 커뮤니케이션에 관한 연구

Abstract

Background As the robot changes into an environment that makes it difficult to see the robot in everyday life, there is an increasing interest in HRI. Therefore, research on emotional interactions in communication between social robot and humans is actively conducted. In this study, emotional communication in HRI can be achieved through the movement of the pupil of the social robot. In other words, we will investigate the possibility of the social robot's eyes as the main mediator of emotional communication. Methods The movement of the pupil of the social robot has emotions, and the user can recognize the intention of the robot and see if there is a difference in user preference according to the combination of components derived for the emotional pupil. For this purpose, the emotional pupil prototype was created based on Type A and Type B images of the existing social robot, and each pupil was derived from the feelings of joy, sorrow, and surprise defined by Ekman 's FACS (1977). Result Type A had no difficulty in feeling the robot's intended emotion than Type B. This suggests that the combination of the pupil elements of Type B is due to the difficulty of conveying clear emotions. However, both Type A and Type B were found to be preferred in each type of preference survey. This result shows that there is a positive reaction to emotional communication through the eyes. Conclusion As social robots can not exclude social relations with humans, mutual exchanges and human experiences through robots are important. Unlike the past, which is centered on industrial robots, the growth of the social robot market is likely to increase the use of emotional communication.
