The pretense of movement: why do we get Cyber-sick?

Motion sickness is an ancient phenomenon, which also occurs in modern virtual reality environments. However, it is still relatively unknown what causes this physical reaction. Suzanne Nooij and her colleagues at the Max Planck Institute for Biological Cybernetics looked at motion sickness occurring while watching moving scenes, and found that it is primarily dependent on the strength of the movement illusion this causes: the stronger the sense of self-motion, the more sickness is experienced. The new findings ask for refinements of previous theories of motion sickness. (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)
