summary This paper utilized protocol analysis to explore further theroles of the sketches as the affordances of functional issues whiledesigning. We found that statistically significant amounts of thedrawing, looking, moving, and perceiving actions have meaningattached to them. In our limited number of subjects, the expert producedmore meaningful actions than the novice. Finally, designers can generatemore meanings from sketches when revising them than when depictingthem.
