Visual intelligence

the long version

In an informal style replete with illustrations, cognitive scientist Donald Hoffman presents the compelling scientific evidence for vision's constructive powers, and in so doing he unveils a grammar of vision - a set of rules that govern our perception of line, color, form, depth, and motion. Hoffman also describes the loss of these constructive powers in patients who have suffered devastating impairments: the artist who can no longer see or dream in color; the woman who, having lost her perception of motion, can no longer cross the street. Finally, Hoffman explores the spinoff of visual intelligence in the arts and technology from the dynamics of film special effects to the visual worlds of virtual reality. - Jacket.
