Abstract

VR technology is a technology that allows a user to experience virtual reality close to reality by wearing an HMD (Head Mounted Display) device. Recently, as the interest in VR technology increases due to the 4th industrial revolution, various HMD devices are spreading. As a result, VR technology is being rapidly applied to various fields, but many of them still experience VR nausea. VR nausea is caused mainly by visual factors, unlike motion nausea, such as car nausea, sea nausea, and air nausea. Such occurrence of VR nausea may be caused by the characteristics of visual information of VR video contents, the hardware characteristics of HMD devices blocking the external visual field, or the physical specificity of individuals, and it is difficult to distinguish the causes. In this paper, we aim to analyze the characteristics of Visually Induced Motion Nausea images focusing on VR video content, which is the cause of VR nausea, in order to search for minimization of Cyber sickness occurrence.

VR 기술이란 HMD(Head Mounted Display)기기를 착용하여 사용자로 하여금 가상 현실(Virtual Reality)을 실제와 가깝게 경험하게 하는 기술이다. 최근 4차 산업혁명으로 VR 기술에 대한 관심이 커짐에 따라 다양한 HMD 기기가 보급되고 있다. 이로써 VR 기술은 다양한 분야에 급속히 접목되고 있으나, 아직 다수가 VR 활용 시 어지럼증과 멀미를 경험하는 실정이다. 사이버 멀미는 차멀미, 뱃멀미, 비행멀미 등의 일반적인 멀미와 달리 주로 시각적 요소에 의해 발생한다. 이러한 사이버 멀미의 발생은 VR 영상 콘텐츠의 시각적 정보의 특성, 외부 시야를 차단하는 HMD 기기의 하드웨어적 특성 또는 개개인의 신체 특이성에 따라 복합적으로 나타날 수 있어 원인을 구별하기 어렵다. 이에 본 논문에서는 사이버 멀미의 발생 원인인 VR 영상 콘텐츠를 중점으로 VIMS(Visually Induced Motion Nausea)영상의 특성을 분석하며, 어지럼증 유발 원인을 분석하고자 한다.
