Talk Title: Fundamental and individual limitations in the perception of 3D motion: Implications for Virtual Reality

Talk Abstract: Neuroscientists have extensively studied motion and depth perception, and have provided a good understanding of the underlying neural mechanisms. However, since these mechanisms are frequently studied in isolation, their interplay remains poorly understood. In fact, I will introduce a number of puzzling deficits in the perception of 3D motion in this talk. Given the advent of virtual reality (VR) and the need to provide a compelling user experience, it is imperative that we understand the factors that determine the sensitivity and limitations of 3D motion perception.

I will present recent work from our lab which shows that fundamental as well as individual limitations in the processing of retinal information cause specific deficits in the perception of 3D motion. Subsequently, I will discuss the potential of extra-retinal (head motion) information to overcome some of these limitations. Finally, I will discuss how individual variability in the sensitivity to 3D motion predicts the propensity for simulator sickness.

Our research sheds light on the interplay of the neural mechanisms that underlie perception, and accounts for the visual system’s sensitivity to 3D motion. Our results provide specific suggestions to improve VR technology and bring virtual reality into the mainstream.
