Don Norman defined an affordance as "the perceived and actual properties of the thing, primarily those fundamental properties that determine just how the thing could possibly be used " Alan Cooper refined this definition by omitting "and actual", identifying perception as the crux of the problem The whole point is that, through a combination of instinct and experience, we expect objects to behave in a certain way based on their appearance and we have very strong expectations if we've used an identical object before If a designer violates one of these expectations, their user will suffer frustration every time they use the interface
Perceptual characteristics of an object that make it obvious what the object can do and how it can be manipulated
An affordance refers to a physical property of something that influences how it can be used For example, the affordances of paper include its properties for being viewed, it's light weight, and so on The nature of a handle on a door determine how one open the door -- by pulling, or pushing, or twisting, and so on
