Abstract

This paper's objectives are to investigate the criteria for ergonomic evaluation of indoor bike coordinated with virtual images, and to compare HMD-based VR bike with 2D-based one. 12 experts performed delphi method with an aim to determine ergonomic evaluation criteria that were classified into 4 categories(Usability, Emotion, User Values, Reality). 2D-based bike and HMD-based one were compared according to part of final criteria through fuzzy-logic question performed by 20 subjects. Though there were no confidential difference in usability, HMD-based VR bicycle resulted in greater scores than 2D-based one in elements related with emotion, user value and reality statistically. It is expected that this research results will be used as references to evaluate ergonomic design of other indoor exercise equipments combined with VR or AR.

본 논문의 목적은 가상 영상과 조합된 실내 자전거의 인간공학적 평가를 위해 세부지표를 도출하고, 일부 지표를 이용하여 기존의 2D 자전거와 HMD 기반의 VR 자전거를 비교 평가하는 것이다. 세부지표는 12명의 인간공학 및 VR 전문가 집단을 선정하여 Delphi 기법을 통해 사용성, 감성, 사용자 가치, 현실감 측면으로 카테고리를 나누고 이하 세부 43개를 선정하였다. 이 중 13개의 지표를 이용하여 2D 자전거와 HMD 기반의 VR 자전거를 피실험자 20명으로 하여금 Fuzzy-Logic Question에 응답하도록 하였다. 사용자 가치 및 현실감과 관련된 지표에서 HMD 기반의 VR 자전거가 높은 점수를 나타낸 반면, 사용성 측면에서는 통계적으로 2D와 유의한 차이를 발생시키지 않았다. 본 연구는 운동기구에 VR기법이 점차 접목되고 있는 상황에서 인간공학적 평가방법을 일부 제시하는데 연구의 의의가 있다.
