Induction of Linear and Circular Vection in Real and Virtual Worlds

摘要

1 Introduction Vection is the illusion of self-motion, usually induced by a visual stimulus. It is important in virtual reality because inducing it in motion simulations can lead to improved experiences. We examine linear and circular vection in commodity level head-mounted displays. We compare the experience of circular vection induced through a real world stimulus, an optokinetic drum, with that experienced through a virtual stimulus. With virtual stimuli, we also compare circular vection with linear horizontal and linear vertical vection. Finally, we examine circular and linear vection in more naturalistic virtual environments. Linear vection was induced more rapidly than any other type, but circular vection occurs more rapidly with a real world stimulus than a virtual one. Our results have practical application and can inform virtual reality design that uses head-mounted display technology and wishes to establish vection.
