Simulator Sickness

A form of motion sickness experienced in virtual reality caused by a mismatch between visual perception of movement and the vestibular system's sense of physical motion. Symptoms include nausea, dizziness, disorientation, and eye strain. Simulator sickness can be triggered by certain locomotion methods (particularly continuous joystick movement), low frame rates, high latency, and certain visual effects. For disabled VR users, simulator sickness adds another layer of accessibility concern on top of physical barriers, as some accessible locomotion alternatives (like joystick movement) may increase sickness while others (like teleportation) reduce it but break immersion.
