| summary | This is a richly illustrated talk about the basis of perception.
What is a picture in vision and touch? Â 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.
John M Kennedy is the author of Drawing and the Blind and of
Psychology of Picture Perception. |
