Abstract

Human has various types of emotions which affect speculation, judgement, activity, and the like at the moment. Specifically, walking is also affected by emotions, because one's emotion status can be easily inferred by his or her walking style. The present research on biped walking with humanoid robots is mainly focused on stable walking irrespective of ground condition. For effective human-robot interaction, however, walking pattern needs to be changed depending on the emotion status of the robot. This paper provides analysis and comparison of gait experiment data for the men and women in four representative emotion states, i.e., joy, sorrow, ease, and anger, which was acquired by a gait analysis system. The data and analysis results provided in this paper will be referenced to emotional biped walking of a humanoid robot.

인간은 다양한 감정을 가지고 있으며 매 시점의 감정 상태에 따라 사고와 판단, 행동이 영향을 받는다. 특히 어떤 사람의 보행하는 모습만 보아도 그 사람의 감정 상태를 짐작할 수 있을 정도로 보행 또한 감정에 영향을 받는다. 현재 휴머노이드 로봇의 이족보행에 관한 연구는 지면의 상태와 상관없이 안정하게 걷는 것을 주로 다루지만 인간과의 교감을 위해서는 감정상태에 따라 보행하는 패턴이 달라질 필요가 있다. 이를 위해 본 논문에서는 보행분석 시스템을 이용해서 네 가지 대표적인 감정(기쁨, 슬픔, 화남, 편안함) 상태에 있는 성인남녀의 보행 데이터를 취득 및 분석하고 상호 특성을 비교하는 연구를 수행했다. 본 논문에서 소개 된 정서적 보행 분석 내용은 휴머노이드 로봇의 정서적 보행에 참고 자료로 사용될 예정이다.
