Abstract
The present study investigated how perspective
elevation and room geometry influenced mental representation
of spatial layout in virtual rooms. One virtual
rectangular and one virtual cylindrical room were constructed.
Subjects observed the spatial layout on the floor
from five perspectives along the vertical dimension of each
virtual room. Then they judged the direction of objects
with respect to egocentric and canonical coordinates. The
analysis of spatial judgment indicated that judgment
accuracy of vertical direction decreased as the perspective
elevated, while global situation awareness was best maintained
at the 45 degree elevation angle. The effect of perspective
elevation on judgment of horizontal direction was only
found in the rectangular room. Moreover, subjects judged
the relative direction between objects more quickly in the
cylindrical room than in the rectangular room. Applications
of these findings to virtual environment design were
discussed.
