Cybersickness

A form of motion sickness experienced during virtual reality use, characterized by symptoms including nausea, disorientation, dizziness, eye strain, and general discomfort. Cybersickness occurs due to sensory conflicts between what the visual system perceives (movement in the virtual environment) and what the vestibular system detects (the body's actual position and motion). It is measured using tools like the Simulator Sickness Questionnaire (SSQ). Cybersickness is a significant accessibility barrier for VR adoption and can be particularly concerning for people with mobility impairments or neurological conditions who may be more susceptible to these sensory conflicts.
