Read this, Experience prototyping, a PDF of a paper from the Symposium on Designing Interactive Systems in 2000 (sponsored by SIGCHI: ACM Special Interest Group on Computer-Human Interaction):
In this paper, we describe “Experience Prototyping” as a form of prototyping that enables design team members, users and clients to gain first-hand appreciation of existing or future conditions through active engagement with prototypes. We use examples from commercial design projects to illustrate the value of such prototypes in three critical design activities: understanding existing experiences, exploring design ideas and in communicating design concepts.
