This document discusses perception and optical illusions. It defines perception as the process of interpreting sensory information to produce meaning. It describes the Gestalt laws of visual perception and some perception constants, like size and shape constancy. It defines optical illusions as images that create perceptions that do not match reality, using techniques like color, light, and patterns to mislead the brain. It provides examples of shape, kinetic, and impossible shape illusions, as well as Op Art, which investigates perceptual effects through art.

color, light and patterns
to create images that
can be misleading to
our brains
