Abstract

During rectilinear locomotion, the focus of expansion identifies the observer's heading. Eye rotation or curvilinear locomotion annihilates this singularity. Computer simulations of eye rotation during circular translation present possible solutions to heading judgement. Specifically, when gaze direction coincides with circular heading, every velocity vector in the image plane becomes linearized. These velocity vectors are tangent vectors of the corresponding flow lines of optical flow. Moreover, the vectors corresponding to the observer's path are all aligned perpendicularly in the image plane, which in turn can be used to determine the observer's path of locomotion.
