This book provides a theoretical framework for design researchers interested in developing
their research work about and with prototypes. It describes prototypes' multiple definitions
and possible functions in the multifaceted landscape of today's design research. Indeed while
the manufacturing and digital evolutions enable and require new types of advanced prototypes
the design evolution as an academic discipline continuously widens its perspectives fields
and research methods among which are the prototypes' applications features and purposes. The
framework originates from an interpretation of these interrelated phenomena and a collection of
case studies. Additionally it defines those criteria that characterize the relation between
the research (context discipline and general scope) and the prototype (nature and specific
aims) and altogether it presents an overview of prototypes' roles in design research.
