Abstract

Users can experience cybersickness when interacting with virtual reality (VR). The symptoms of cybersickness are similar to those of motion sickness which include eye fatigue, disorientation, and nausea. Despite the longstanding interest of user's discomfort, inconsistent results have been drawn on the underlying mechanisms and solutions of cybersickness. In this study, we propose an integrated view of cybersickness connecting causes of the symptoms, human perception model, and measurements of cybersickness. Cybersickness-related factors of previous research are reorganized into content, hardware, and human factors as well as analyzed in terms of VR fidelity. Also, pros and cons that measure the degree of cybersickness are discussed.

사이버멀미란 가상현실을 경험할 때 발생하는 멀미와 유사한 증상으로 눈의 피로, 방향감각 상실, 메스꺼움 등을 동반한다. 사이버멀미는 가상현실 산업의 확산을 위한 선결 과제로 여겨지고 있으며, 해당 증상을 완화하기 위한 다양한 연구가 시도되어 왔다. 그러나 아직까지 사이버멀미의 발생 기전과 해결책에 관한 명확한 결론은 도출되지 못하였다. 본 논문은 사이버멀미 현상을 보다 입체적으로 이해하기 위해 해당 현상을 관통하는 주요 구성 요소인 사이버멀미의 유발 원인, 인간의 인지체계, 사이버멀미의 측정 방법을 연결한 통합적 관점을 제시하였다. 특히 현재까지 알려진 사이버멀미의 유발 원인을 콘텐츠, 하드웨어, 사용자 특성 측면으로 새로이 분류하였다. 또한 사이버멀미 관련 요인에 대한 기존의 연구를 콘텐츠의 가상현실 충실도 관점에서 해석하여 상이한 연구 사이의 일관성을 도출하였다. 마지막으로 사이버멀미를 정량화하기 위한 객관적, 주관적 측정 도구를 살펴보고 각각의 한계점에 대해 논의하였다.
