Interactive System Design

I adopted this book as support textbook for my course on information retrieval systems. The book provides a crisp and very informative view on the problems and steps related to analysis and design of interactive systems. It covers most of the core topics relevant to the analysis of interactive systems (problem definition, task analysis, models, system analysis, system evaluation) and those related with user interface design (interaction styles, mental models, conceptual design). These topics are dealt with sufficient detail to get a reasonable understanding both of abstract and concrete aspects. The few complete examples guide the reader through most of the issues. Some topic (like experimental evaluation) is very detailed. Treatment is extremely clear and vivid. I definitely recommend this book to anybody interested in design of interactive systems.
