Gibson was interested in the structures of the ambient optic array that are invariant, or structures that remain static regardless of the actions of the observer. For example, Gibson noted that the upper hemisphere of the array (the sky) tends to be much less structured and brighter than the lower hemisphere (the cluttered earth).
Gibson began his undergraduate career at Northwestern University, but transferred after his freshman year to Princeton University, where he majored in philosophy.While enrolled at Princeton, Gibson had many influential professors including Edwin B. Holt who advocated new realism, and Herbert S. Langfeld who had taught Gibson's experimental psychology course.
Gregory's ideas ran counter to those of the American direct realist psychologist J. J. Gibson, whose 1950 The Perception of the Visual World was dominant when Gregory was a younger man. Much in Gregory's work can be seen as a reply to Gibson's ideas, and as the incorporation of explicitly Bayesian concepts into the understanding of how sensory ...
Various configurations of optical flow sensors exist. One configuration is an image sensor chip connected to a processor programmed to run an optical flow algorithm. Another configuration uses a vision chip, which is an integrated circuit having both the image sensor and the processor on the same die, allowing for a compact implementation.
In psychology, affordance is what the environment offers the individual. In design, affordance has a narrower meaning; it refers to possible actions that an actor can readily perceive. American psychologist James J. Gibson coined the term in his 1966 book, The Senses Considered as Perceptual Systems, [1] and it occurs in many of his earlier ...

This school of thought is heavily influenced by the writings of Roger Barker and James J. Gibson and stands in contrast to the mainstream explanations of perception offered by cognitive psychology .

From Gibson's early work derived an ecological understanding of perception known as perception-in-action, which argues that perception is a requisite property of animate action. It posits that, without perception, action would be unguided, and without action, perception would serve no purpose.
