Q Paper-Based Prototyping: Many partici-
patory design techniques use paper-based
mock-ups and prototypes to repre-
sent design ideas early in the
development process [e.g.,
14]. Such techniques pro-
vide a way for stakehold-
ers to comment on the
details of the design and
the extent to which it
meets the user’s charac-
teristics and needs. In
capturing the primary
concerns of the users
and, potentially, the major information
flows likely to affect the system, the rich
picture places the emerging design in its
overall social and technical context.
