• Research over the past 20 years has consistently shown that egocentric distance is underperceived in virtual environments (VEs) compared with real environments. In 2 experiments, judgments of object distance (Experiment 1) and object size (Experiment 2) improved after a brief period of walking through the VE with continuous visual feedback. Whereas improvement of blind-walking distance judgments could be attributable to recalibration of walking, improvement in perceived size is considered evidence for rescaling of perceived space, whereby perceived size and distance increased after walking interaction. Furthermore, improvements in judged distance and size transferred to a new VE. Distance judgments, but not size judgments, continued to improve after additional walking interaction in the new VE. These results have theoretical implications regarding the effects of walking interaction on perceived space, and practical implications regarding methods of improving perceived distance in VEs. Public Significance Statement Perceived egocentric distance (distance from oneself to another location) is consistently underperceived in virtual reality (VR) compared with relatively accurate real world perception. In this study, a brief period of walking through the virtual environment (VE) with continuous visual feedback improved perceived distance as measured by a walking response and a size response. For both response measures, the improvement caused by walking interaction generalized to a new VE that had not been previously experienced. The finding that improvement generalized to a new VE is of practical significance, and also suggests that the perceptual deficiencies in VR are associated with the VR display rather than the VE itself.
