Cybersickness

Overview

Virtual reality sickness occurs when exposure to a virtual environment causes symptoms that are similar to motion sickness symptoms.[1] The most common symptoms are general discomfort, headache, stomach awareness, nausea, vomiting, pallor, sweating, fatigue, drowsiness, disorientation, and apathy.[2] Other symptoms include postural instability and retching.[2] Virtual reality sickness is different from motion sickness in that it can be caused by the visually-induced perception of self-motion; real self-motion is not needed.[1] It is also different from simulator sickness; non-virtual reality simulator sickness tends to be characterized by oculomotor disturbances, whereas virtual reality sickness tends to be characterized by disorientation.[3]

가상환경멀미(또는 사이버멀미)를 유발하는 것으로 알려진 여러 요인 중 저희는 충실도(fidelity) 요인을 주의 깊게 살펴보고 있습니다. 2016년 McMahan 연구진이 주장한 AFFECT 모델을 근거로, 높은 디스플레이 충실도(display fidelity) 환경에서 인터랙션 충실도(interaction fidelity)와 시나리오 충실도(scenario fidelity)가 멀미에 미치는 영향을 연구합니다. 특히 모션 캡쳐 장비를 이용한 사용자의 신체 흔들림(body sway) 지표를 통해 보다 비침습적이고 객관적으로 멀미정도를 측정하고자 합니다.
