During forward locomotion, the objects in the environment create a pattern of expanding visual motion called optic flow. The visual system extracts directional information about translation in the optic flow field and disentangles it from confounding motion. From optic flow analysis, humans can gauge traveled distance and accurately perceive their heading direction. Biological motion refers to limb movements during walking. In natural locomotion, articulation and translation are linked such that articulation delivers cues about the speed and direction of the walker. These cues can potentially facilitate locomotion. But biological motion is complex and introduces noise into the optic flow field. This additional noise could impair optic flow analyses, as previously seen for heading perception. Prior studies gave evidence for independent information processing of both motion types. It remains interesting to study concurrent processing of both optic flow and biological for spatial navigation. My research ties in with the overall theme of visual perception of optic flow and biological motion for locomotion and focuses on two major topics. The first one relates to ensemble perception mechanisms of biological motion during heading through a crowd. The second one investigates travel distance estimation through a crowded environment.
