Title: Stereoscopic 3D optic flow distortions caused by mismatches between image acquisition and display parameters (HVEI-009)

Speaker: Alex Hwang, Harvard Medical School (USA)

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.

Biography: Alex D. Hwang received BS in mechanical engineering from the University of Colorado Boulder (1999), and received MS (2003) and Ph.D. in computer science from the University of Massachusetts Boston (2010). Since then, he has worked at Schepens Eye Research Institute in Boston MA as a postdoctoral research fellow. He became an Investigator and is appointed as an Instructor of Ophthalmology at Harvard Medical School (2015). His work has focused on bioengineering and low vision rehabilitation.
