Abstract
As the use of virtual and augmented reality applications becomes more common, the need to fully understand how observers perceive spatial relationships grows more critical. One of the key requirements in engineering a practical virtual or augmented reality system is accurately conveying depth and layout. This requirement has frequently been assessed by measuring judgments of egocentric depth. These assessments have shown that observers in virtual reality (VR) perceive virtual space as compressed relative to the real-world, resulting in systematic underestimations of egocentric depth. Previous work has indicated that similar effects may be present in augmented reality (AR) as well. This paper reports an experiment that directly measured egocentric depth perception in both VR and AR conditions; it is believed to be the first experiment to directly compare these conditions in the same experimental framework. In addition to VR and AR, two control conditions were studied: viewing real-world objects, and viewing real-world objects through a head-mounted display. Finally, the presence and absence of motion parallax was crossed with all conditions. Like many previous studies, this one found that depth perception was underestimated in VR, although the magnitude of the effect was surprisingly low. The most interesting finding was that no underestimation was observed in AR.

As the use of virtual and augmented reality applications becomes more common,
the need to fully understand how observers perceive spatial relationships grows
more critical. One of the key requirements in engineering a practical virtual or
augmented reality system is accurately conveying depth and layout. This
requirement has frequently been assessed by measuring judgments of egocentric
depth. These assessments have shown that observers in virtual reality (VR)
perceive virtual space as compressed relative to the real-world, resulting in
systematic underestimations of egocentric depth. Previous work has indicated
that similar effects may be present in augmented reality (AR) as well.
This paper reports an experiment that directly measured egocentric depth
perception in both VR and AR conditions; it is believed to be the first
experiment to directly compare these conditions in the same experimental
framework. In addition to VR and AR, two control conditions were studied:
viewing real-world objects, and viewing real-world objects through a
head-mounted display. Finally, the presence and absence of motion parallax was
crossed with all conditions. Like many previous studies, this one found that
depth perception was underestimated in VR, although the magnitude of the effect
was surprisingly low. The most interesting finding was that no underestimation
