An increasing recognition of the role of the human-system interface is leading to new extensions and styles of specification. Techniques are being developed that facilitate the expression of user-oriented requirements and the refinement and checking of specifications of interactive systems. This book reflects the state of the art in this important area and also contains a summary of working group discussions about how the various techniques represented might be applied to a common case study.
