Abstract
We analyze the impact of common stereoscopic 3D (S3D) depth distortion on S3D optic flow in virtual reality (VR) environments. The depth distortion is introduced by mismatches between the image acquisition and display parameter. The results show that such S3D distortions induce large S3D optic flow distortions and may even induce partial/full optic flow reversal within a certain depth range, depending on the viewer's moving speed and the magnitude of S3D distortion introduced. We hypothesize that the S3D optic flow distortion may be a source of intra-sensory conflict that may be a source of visually induced motion sickness (VIMS) in S3D.
