This is a richly illustrated talk about the basis of perception.
What is a picture in vision and touch? Kennedy will offer new theories of figure-ground in cave art, depth perception from Renaissance perspective, and communication via unrealistic representation. Common features in pictures by the sighted and the blind (Esref & EW) tell us about 6 kinds of figure-ground surface edges, a principle evident in cave art. In touch as well as vision these edges are perceived from a vantage point — so Renaissance linear perspective applies to the visible and the tactile environment. Showing the environment unrealistically is a way of creating pictorial metaphors. Blind and sighted artists depict impressions and thoughts metaphorically. Kennedy will present 8 ways to structure visual input, offer a new theory of Gestalt grouping and discuss recent experiments on illusions and perception of direction.
