, Perception - Affordance
What is affordance?
Affordance hints to the user what to do with an object.
The four main types of affordance
False affordance – perceived affordance misleads the user, an
example of this would be an annoying pop-up add where-upon trying
to close the tab [by clicking the red cross] another add appears.
Perceptible affordance – The objects characteristic implies what to
do with the object. It is the basic definition of affordance.
Hidden affordance – The object has affordances which are less
obvious, an example being a dropdown menu which is not yet
visible.
Correct rejection – the object has no indication as to what it does as This image displays a typical example of af
it doesn’t do anything.
