Verification of the influencing factors concerning the accuracy of distance perception in immersive virtual environment

"Immersive Virtual Environment (IVE)" could be useful for the field of architecture. This paper focused on the factors for a grasp of an accurate distance in the IVE. A total of 10 normal sight subjects were individually asked to match up their image distances to the standard distances, which were between the sphere and the subject in the IVE. We conclude that the image distances are close to the standard distances, when "3m" is the standard distance or the subject attention to the distance that is between the sphere and a floor.
