We quantify to what degreeusers can unknowingly be redirected in order to guidethem through VEs in which virtual paths differ fromthe physical paths. We further introduce the concept ofdynamic passive haptics by which any number of virtualobjects can be mapped to real physical proxy propshaving similar haptic properties (i. e., size, shape, andsurface structure), such that the user can sense thesevirtual objects by touching their real world counterparts.Dynamic passive haptics provides the user withthe illusion of interacting with a desired virtual objectby redirecting her to the corresponding proxy prop.We describe the concepts of generic redirected walkingand dynamic passive haptics and present experimentsin which we have evaluated these concepts. Furthermore,we discuss implications that have been derivedfrom a user study, and we present approachesthat derive physical paths which may vary from thevirtual counterparts. ER
