I'm looking for a word used in interaction design and probably in other fields as well.
It's used for the following purpose:
If a door has one handle which is a flat surface and another hanlde which is a bar then the bar has a ___ for being pulled, and the flat surface has a ___ for being pushed.
What is this word?
It would be used to describe that an object complies with its "desire" or not to be able to make the user experience as intuitive as possible.
