Gradient of Flow - In an optic flow pattern, a gradient is created by movement of an observer through the environment. The "gradient" refers to the fact that the optic flow is rapid in the foreground and becomes slower as distance from the observer increases.

What is the gradient of flow?
Horizontal frictionless flow in which isobars and streamlines coincide, or equivalently, in which the tangential acceleration is everywhere zero. The balance of normal forces (pressure force, Coriolis force, centrifugal force) is then given by the gradient wind equation.
What is optic flow in psychology?
Optic flow can be defined as the motion of all the surface elements from the visual world. As you move through the world, the objects and surfaces within the visual environment flow around you. The human visual system can determine your current direction of travel from the movement of these surfaces.
What two things does optic flow tell the observer?
1) emphasizing the moving observer- how perception occurs as a person is moving through the environment. 2) identifying information in the environment that the moving observer uses for perception.
What is optic flow Gibson?
The concept of optic flow, a global pattern of visual motion that is both caused by and signals self-motion, is canonically ascribed to James Gibson's 1950 book “The Perception of the Visual World.” There have, however, been several other developments of this concept, chiefly by Gwilym Grindley and Edward Calvert.
