Good Affordance
Buttons should look like buttons.
They should look like something you
would be able to "Press" in order to
take a specific action. All UI
mechanisms need to be meaningful and
clear.
This is good affordance. Have
you noticed instances where good
affordance is not given? There
seems to be a new trend to not bother
with the illusions that provide
these visual clues. We protest.
Good affordance is an interaction
design principle that we are committed
to.
