here's a slideshow from "slideshare.com" that talks about experience protoyping
(click the "right" direction arrow to view each pages)
it covers the stage from "research and discovery" all the way to "realization," and has insights from Bill Mogridge (from IDEO), Jane Fulton Suri, etc.
this information might be relevant for David Quans core class (those of us who have to experience prototype still)
main ideas: collaboration/interdisciplinarity, experience, integration
