Spatial updating experiments in Virtual Reality: What makes the world turn around in our head?

Discontinuous (jumplike) spatial updating yielded similar performance. Photo-realistic visual stimuli from well-known environments including an abundance of salient landmarks are sufficient to trigger spatial updating and hence turn the world inside our head, even without corresponding vestibular cues. This result conflicts with the prevailing opinion that vestibular cues are required for proper updating of ego-turns. We believe that this apparent conflict can be primarily explained by the immersiveness of our visualization setup and the abundance of natural landmarks in a well-known environment.
