Signifiers
"A 'signifier' is some sort of indicator, some signal in the physical or social world that can be interpreted meaningfully."
- Don Norman (http://jnd.org/dn.mss/signifiers_not_affordances.html)
- Physical properties of an object (knob, switch, button, handle)
- Label or sign
Constraints
"something that limits or restricts someone or something"
-
physical
(certain actions not physically possible) -
logical
(only a certain action makes logical sense) -
cultural
(we have learned that certain things should or should not be done)
Mappings
"the relationship between two
things, in this case between the controls and their movements and the
results in the world"
- Don Norman (The Design of Everyday Things)
