Abstract

This paper presents an interactive wind system that generates artificial winds in a virtual reality (VR) environment according to online user inputs from a steering wheel and an acceleration pedal. Our system is composed of a head-mounted display (HMD) and three electric fans to make the user sense touch from the winds blowing from three different directions in a racing car VR application. To evaluate the effectiveness of the winds for reducing VR cybersickness, we employ the simulator sickness questionnaire (SSQ), which is one of the most common measures for cybersickness. We conducted experiments on 13 subjects for the racing car contents first with the winds and then without them or vice versa. Our results showed that the VR contents with the artificial winds clearly reduce cybersickness while providing a positive user experience.

본 논문은 자동차 핸들과 가속 페달로부터의 온라인 사용자 입력에 따라 Virtual Reality (VR) 환경에서 인공적인 바람을 생성하는 상호작용형 윈드 시스템을 제안한다. 제안된 시스템은 사용자가 레이싱 자동차 VR 응용 콘텐츠에서 세 방향으로부터 불어오는 바람으로부터 촉감을 느끼도록 하기 위해 머리장착형 디스플레이(Head-Mounted Display: HMD)와 세개의 선풍기로 구성된다. VR 멀미를 개선하는 것에 대한 바람의 효과성을 평가하기 위해, 본 논문은 멀미에 대한 가장 기본적인 척도 중의 하나인 SSQ (simulator sickness questionnaire)를 도입한다. 13명의 피험자들을 대상으로 바람이 있는 경우와 그 다음 그렇지 않은 경우 또는 그 역으로 레이싱 자동차 콘텐츠에 대한 실험을 수행하였다. 실험 결과는 인공적인 바람을 사용하는 경우 긍정적인 사용자 경험을 제공하면서 명확하게 멀미를 개선하는 것을 보여주었다.
