perception
A subset of HCI
Subtheories of perception include:
- color theory
- preattentive processing theory
- gestalt
- structured object perception
- affordances (though this is more a combination of perception and action, rather than a strict subtheory of perception)

FUN FACTS
- The brain uses 25% of its processing and 60% of the cerebral cortex for vision
History
- Many ancient theories assumed that the eye itself was emitting something, though ancient philosophers like Aristotle did correctly believe that fiery items created particles that reflected into the eyes.
- The first serious literature on it was Ibn Al-Haytham’s Book of Optics
- affordances were first described by Norman’s The Psychology of Everyday Things
