A number of investigators have reported that distance judgments in virtual environments (VEs) are systematically smaller than distance judgments made in comparably-sized real environments. Many variables that may contribute to this difference have been investigated but none of them fully explain the distance compression. One approach to this problem that has implications for both VE applications and the study of perceptual mechanisms is to examine the influence of the feedback available to the user. Most generally, we asked whether feedback within a virtual environment would lead to more accurate estimations of distance. Next, given the prediction that some change in behavior would be observed, we asked whether specific adaptation effects would generalize to other indications of distance. Finally, we asked whether these effects would transfer from the VE to the real world. All distance judgments in the head-mounted display (HMD) became near accurate after three different forms of feedback were given within the HMD. However, not all feedback sessions within the HMD altered real world distance judgments. These results are discussed with respect to the perceptual and cognitive mechanisms that may be involved in the observed adaptation effects as well as the benefits of feedback for VE applications.
