 This book constitutes the thoroughly refereed post-proceedings of the 9th International Workshop on the Design, Specification, and Verification of Interactive Systems, DSV-IS 2002, held in Rostock, Germany in June 2002.
The 19 revised full papers presented have gone through two rounds of reviewing, selection, and improvement. All aspects of the design, specification, and verification of interactive systems from the human-computer interaction point of view are addressed. Particular emphasis is given to models and their role in supporting the design and development of interactive systems and user interfaces for ubiquitous computing.
