Introduction of Cybersickness

Abstract

With an introduce of virtual reality (VR) technology, the issue of unpleasant side effect of VR immersion has been raised as “cybersickness.” Although exact mechanism of cybersickness is still elusive, sensory conflict theory has been generally accepted as in classic motion sickness. The absence of expected correlated vestibulo-proprioceptive sensory information during VR experience causes sensory conflict, which leads to dizziness, disorientation, nausea and fatigue. Herein, we review the recent literature to build the conceptual scheme for understanding cybersickness. From the brief description of motions sickness, assessment and management of cybersickness is also outlined. Key words: Dizziness ㆍ Motion sickness ㆍ Virtual reality
