Abstract

In this study, the degree of motion sickness displayed according to actions in virtual reality is measured based on the SSQ tool, a measuring tool, and factors and symptoms affecting cyber motion sickness are investigated through comparative analysis. In the first experiment, the operation method experiment, the simple operation method is measured to be highly affected by the Nausea factor. As symptoms of this, nausea, burp and headache symptoms were developed. In the second experiment, the larger the body rotation radius, the higher the motion sickness was measured, and the greater the influence of Nausea factors. Symptoms of this were the symptoms of burping, headaches, and a full head. In the third experiment, the physical mobility experiment, motion sickness was measured highly in the non-action controller. It was measured to be greatly affected by the Nausea factor. Symptoms of this include fever, headache, and a full head. Through this study, we found that the more fixed and simple the body is operated in virtual reality, the more sensitive the user is to motion sickness, and the larger the radius of rotation, the more sensitive it is to motion sickness. This study is meaningful in identifying factors and symptoms that affect motion sickness and VR manipulation, and is expected to be used by developers in the future to recognize the degree and symptoms of motion sickness of users and to develop content.

본 연구는 멀미 측정 도구인 SSQ도구를 바탕으로 가상현실에서 조작행위에 따라 나타나는 멀미 정도를 측정하여 비교분석을 통해 사이버멀미에 영향을 미치는 요인 및 증상을 규명하는 데 목적이 있다. 연구결과 첫 번째 실험인 조작방식실험에서는 간단한 조작방식이 멀미가 높게 측정되었으며 Nausea요인의 영향을 크게 받는 것으로 측정되었다. 이에 대한 증상으로 Nausea, Burping, Headache증상이 발현되었다. 두번째 신체회전방식 실험에서는 신체회전반경이 클수록 멀미가 높게 측정되었으며 Nausea요인의 영향을 크게 받는 것으로 측정되었다. 이에 대한 증상으로 Burping, Headache, Fullness of head증상이 발현되었다. 세번째 신체이동방식 실험에서는 행위를 수반하지 않은 컨트롤러의 이동방식이 멀미가 높게 측정되었으며 Nausea요인의 영향을 크게 받는 것으로 측정되었다. 이에 대한 증상으로 Sweating, Headache, Fullness of head증상이 발현되었다. 본 연구를 통해 가상현실에서 신체(고개, 상체, 하체)가 고정되고 조작이 단순 할수록 사용자는 멀미에 민감하게 반응하며, 신체회전에 있어 회전반경이 클수록 멀미에 민감하게 반응하는 것을 확인하였다. 본 연구는 VR조작행위에 대한 멀미와 영향을 미치는 요인과 증상을 규명하는데 의의가 있으며 향후 VR콘텐츠 개발자들이 사용자의 특정 행위 멀미 정도와 증상에 관하여 인지하고 콘텐츠 개발에 활용 될 것으로 기대한다.
