Document Summary

Spatial vision, where it is direct to our surroundings: perception of direction. We tend to behave like a cyclops. Somehow the brain combines the two eyes, allowing us to see the world as a whole rather than seeing two. Absolute direction is an object with respect to me. Relative direction is an object with respect to something else. It has minimal amount of information for the brain to process. Absolute direction requires you to know where your eye is, what you are looking at, how close it is respect to yourself and many more. First law: although we have two eyes we see as though it is from a single eye (the cyclopean eye) located midway between the two eyes. We have two separate eyes, trying to look at a single reference point. Rather than a dominant eye, it uses midway between the two eyes as a reference point.
