Visual analysis of gait as a cue to identity

Visual analysis of gait as a cue to identity
Visual analysis of gait as a cue to identity
For humans, the ability to discriminate between, and to identify, others is paramount. The most obvious way this is accomplished is by means of face recognition. However, this is not the only method available. The present article reports on two experiments designed to see whether gait can be used as a reliable cue to identity.
Experiment One showed that the human visual system was sophisticated enough to learn to identify six individuals on the basis of their gait signature under conditions of simulated daylight, simulated dusk and point-light displays. It thus appeared that gait-related judgements could be made, and furthermore, that these judgements were possible without reliance on shape information.
Experiment Two suggested that even under adverse viewing conditions involving a single brief exposure, humans could identify a target from a walking identity parade at greater than chance levels. These results emerged regardless of the lighting conditions, and were largely independent of the gender of the target walker. As such, the present results suggest that gait could be used as a reliable means of discriminating between individuals, and the importance of such an identity cue, in conditions in which the face is obscured, are discussed.

Abstract

For humans, the ability to discriminate between, and to identify, others is paramount. The most obvious way this is accomplished is by means of face recognition. However, this is not the only method available. The present article reports on two experiments designed to see whether gait can be used as a reliable cue to identity.
Experiment One showed that the human visual system was sophisticated enough to learn to identify six individuals on the basis of their gait signature under conditions of simulated daylight, simulated dusk and point-light displays. It thus appeared that gait-related judgements could be made, and furthermore, that these judgements were possible without reliance on shape information.
Experiment Two suggested that even under adverse viewing conditions involving a single brief exposure, humans could identify a target from a walking identity parade at greater than chance levels. These results emerged regardless of the lighting conditions, and were largely independent of the gender of the target walker. As such, the present results suggest that gait could be used as a reliable means of discriminating between individuals, and the importance of such an identity cue, in conditions in which the face is obscured, are discussed.
