Motion sickness is an age-old malady that is increasingly common in simulators, virtual environments, and video games.
Traditionally, theories of motion sickness etiology have been based on the concept of intersensory conflict. However, conflict-based theories have low predictive power, and may not be falsifyable. I offer a new theory of motion sickness etiology that is based on perceptually-guided control of the body in moving environments. I will describe several studies that provide support for the new theory, and discuss implications for our understanding of perception-action, and for the prediction and prevention of motion sickness.
