Influence of Optical Flow Image on Road Width Perception

Drivers tend to decelerate their vehicles while driving through narrow roads for fear of accidents, even if there is no such risk. In this study, it is hypothesized that drivers tend to underestimate the road width under a radical flow image condition as compared to under a stationary image condition. This hypothesis has been verified by performing alley experiments in VR environments. In these experiments, distortions of participants' visual space against the physical Cartesian coordinate space are measured. Results of these experiments show that the visual space under the radical flow image condition deflects inward as compared to that under the stationary image condition.
