Abstract: Rapid progress in the understanding of the perception of spatial layout is credited to J. J. Gibson's (1979) concept of information. Ecological research has focused on the wealth of information based in the continuous change and invariant structures of optic flow, information that can specify events and the stable properties of objects. Recent demonstrations that have shown that instantaneous optic flow not only contains informative structure but also controls perception suggest that previous claims that static displays are necessarily impoverished and ambiguous were exaggerated. Future research efforts should consider the potential of both instantaneous and ongoing optic flow to provide information about the world and even about the dynamics of events.
