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