초록
본 연구는 가상현실 콘텐츠 경험 이전에 기본 주시눈 위치의 패턴을 이용해 영상멀미의 민감도를 예측할 수 있는 방법론 개발에 그 목적이 있다. 본 실험에는 20명 (여자 10명, 평균 나이: 28.42±3.17세)의 피험자가 참여하였다. 실험 참가자들은 5분 동안 기본 주시눈 위치의 패턴을 측정하고 가상현실 콘텐츠를 15분 동안 시청하였다. VR 콘텐츠 시청 후에 ‘Simulator Sickness Questionnaire (SSQ)’ 설문을 통해 영상멀미에 대한 주관적인 경험을 실험 참가들로부터 보고 받았다. 기본 주시눈 패턴과 SSQ 점수는 피어슨 상관분석 및 독립성분 t검정을 통해 유의성을 확인하고 다중회귀분석을 통해 예측모델을 도출하였다. 분석결과, 기본 주시눈 위치의 패턴 (PCPA & PCPR)은 SSQ 점수와 통계적으로 유의한 차이가 있었고 강한 혹은 중간 양의 상관관계가 있음을 확인하였다. 또한, 도출된 예측모델은 새로운 실험참가자 10명을 대상으로 정확도를 검증하였고 설문과 예측모델에 의한 SSQ 점수 사이에 강한 양의 상관관계와 낮은 편차가 있음을 확인하였다.
Abstract
The aim of this study is to predict the sensitivity of motion sickness (MS) using pattern of cardinal gaze position (CGP) before experiencing the virtual reality (VR) content. Twenty volunteers of both genders (8 females, mean age 28.42 ± 3.17) participated in this experiment. They was required to measure the pattern of CGP for 5 minute, and then watched VR content for 15 minute. After watching VR content, subjective experience for MS reported from participants using by 'Simulator Sickness Questionnaire (SSQ)'. Statistical significance between CGP and SSQ score were confirmed using Pearson correlation analysis and independent t-test, and prediction model was extracted from multiple regression model. PCPA & PCPR indicators from CGP revealed significantly difference and strong or moderate positive correlation with SSQ score. Extracted prediction model was tested using correlation coefficient and mean error, SSQ score between subjective rating and prediction model showed strong positive correlation and low difference.
