Do Textures and Global Illumination Influence the Perception of Redirected Walking Based on Translational Gain

For locomotion in virtual environments (VE) the method of redirected walking (RDW) enables users to explore large virtual areas within a restricted physical space by (almost) natural walking. The trick behind this method is to manipulate the virtual camera in an user-undetectable manner that leads to a change of his movements. If the virtual camera is manipulated too strong then the user recognizes this manipulation and reacts accordingly. We studied the effect of human perception of RDW under the influence of the level of realism in rendering the virtual scene.
