Human Vision: Perception CS 498: Virtual Reality UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN Eric Shaffer Visual Perception Transition from discussing physiology of vision to perception. How do our brains interpret the world around us so effectively? Eric King. Humans perceive color when light enters the eye and is detected by the photoreceptors, called cones, which are mainly located in the fovea. We have trichromatic color vision which means we have three different kinds of cones that detect a specific wavelength of light, namely short (blue), medium (green), and long (red). How we perceive color also depends on how dim or bright the light is. . Introduction. Sensation.
