Motion Sickness

A condition characterized by nausea, disorientation, and discomfort experienced when using virtual reality, simulators, or viewing motion-heavy content. In VR accessibility, motion sickness disproportionately affects some users and must be considered in interface design. Symptoms can be triggered by sensory conflicts between visual motion cues and vestibular (inner ear) signals. Minimizing unnecessary environmental motion and providing stable reference points can reduce motion sickness incidence.
