In the book, Norman introduced the term affordance as it applied to design,[3]: 282 borrowing James J. Gibson’s concept from ecological psychology.[1] In the revised edition of his book in 2013, he also introduced the concept of signifiers to clarify his definition of affordances.[4] Examples of affordances are doors that can be pushed or pulled. These are the possible interactions between an object and its user. Examples of corresponding signifiers are flat plates on doors meant to be pushed, small finger-size push-buttons, and long and rounded bars we intuitively use as handles. As Norman used the term, a door affords pushing or pulling, and the plate or button signals that it is meant to be pushed, while the bar or handle signals pulling.[3]: 282–3 [5]: 9 Norman discussed door handles at length.[6][5]: 10, 87–92
Norman Door.
In essence, if a door does not accurately broadcast its proper use, the door is wrong.
The Design of Everyday Things is a fantastic book by the man the Norman Door is named after.
