Our lives are spent identifying, judging and using objects, largely without any direct input from our non-visual senses. This process makes major use of the visual structures built up within our brains from superficial characterizations of the surrounding object world. It is truly amazing how much we can rely (usually with high precision) upon the visually perceived properties of objects when we have no other direct sensory knowledge. We learn to see at such an early age, under the influences of such a battery of sensory inputs, that the whole process is still not firmly understood. The heuristic processes of the brain in developing a model of the egocentric world derives from the encoding of sensory experience into that model by calibrating the observed object world on the basis of "hardwired" physiological reactions and subsequent learned world parameters. The great contribution of the visual sense is that it frees us from direct contact requirements - moving the recognition of possible difficulties to a (somewhat) more remote future, enabling a planned rather than instinctive response. This paper discusses the development of visual perception in the brain, the unification of sensory system inputs into a coherent world structure, and some processes the individual uses inthe organization of the visual field for most useful extraction of information.
