Distortion of visual localization in three-dimensional virtual space

With applications increasingly using 3D displays, it is important to examine how humans perceive objects located within this medium. The current study examined memory accuracy for the location of a briefly presented visual object when presented using a 3D projector. We observed distortions of depth perception in visual space (i.e., the remembered location of a visual object tended to be underestimated). In addition, we found that this underestimation was not affected by the depth of a fixation point. These results suggest that memorized locations of visual objects tend to be biased toward the observer. We further discuss implications for these findings.
