Aristotle: The Godfather of Augmented Reality.

What is Augmented reality? For that matter what is reality?
Everyday we augment our reality. Our brains change the way we perceive things around us. Everyone's perceptions differ slightly, no one sees or hears things in exactly the same way. Our brains are particularly good at filling in or leaving out bits of information that make up our perception of reality.

Visual and aural stimulus can change our perception of reality. Our physiological state can be altered by sight and sound. Our reality becomes augmented. And all this without any technology!

Aristotle in his work on tragedy— The Poetics —understood the place of the senses in augmenting people's reality. He set down clear guidelines as to the best way to affect people's state of mind. He saw that this idea of the artist (or Poet) being able to "conjure" dead heroes from the past, to unleash the demons from the underworld and to kill and re-kill loved characters was almost part of a divine calling. The power the Poet could hold over his audience was great, and therefore, the poet had a grave responsibility to perform the best he could. Aristotle's Poetics gives a framework for the Poets to adhere to in order that the performance touch as many of the senses as possible and therefore elicit the most powerful response from the audience. This notion of impacting people by predetermined methods flows through all creative production work.

Disney of course has been using prescribed forms and colours to deliver stories which make us feel a certain way. Character design often uses set shapes to give us emotional clues about a person we see on screen. Round shapes for soft, fun, friendly characters and Angular shapes for evil and menacing characters.
