Motion Sickness

Motion sickness, particularly in virtual reality (VR) and autonomous vehicle contexts, arises from sensory conflicts between visual and vestibular systems. Current research focuses on developing computational models, often based on subjective vertical conflict theory, to predict and mitigate sickness, incorporating visual vertical information alongside vestibular inputs. These models are being validated through user studies comparing different control mechanisms (e.g., balance boards vs. joysticks) and display techniques (e.g., unwinding rotations), aiming to identify factors that minimize discomfort and improve user experience. This work has implications for improving VR applications and the design of safer and more comfortable autonomous vehicles.
