Abstract

A key requirement for a sense of presence in Virtual Environments
(VEs) is for a user to perceive space as naturally as possible.
One critical aspect is distance perception. When judging
distances, compression is a phenomenon where humans
tend to underestimate the distance between themselves and
target objects (termed egocentric or absolute compression),
and between other objects (exocentric or relative compression).
Results of studies in virtual worlds rendered through
head mounted displays are striking, demonstrating significant
distance compression error. Distance compression is a multisensory
phenomenon, where both audio and visual stimuli
are often compressed with respect to their distances from the
observer. In this paper, we propose and test a method for
reducing crossmodal distance compression in VEs. We report
an empirical evaluation of our method via a study of 3D
spatial perception within a virtual reality (VR) head mounted
display. Applying our method resulted in more accurate distance
perception in a VE at longer range, and suggests a modification
that could adaptively compensate for distance compression
at both shorter and longer ranges. Our results have
a significant and intriguing implication for designers of VEs:
an incongruent audiovisual display, i.e. where the audio and
visual information is intentionally misaligned, may lead to
better spatial perception of a virtual scene.
