Traditional visual design expresses information in fixed forms, such as print or film, so the message can be stored or distributed. With interactive media and continuously updated information, communication entails a new, more dynamic set of design problems. In this book Suguru Ishizaki offers a theoretical framework for dealing with the challenges and opportunities of what he calls ''dynamic design.'' His approach incorporates a community of collaborating agents that control design solutions in response to a changing context. He illustrates his ideas with several examples, such as expressive e-mail and responsive maps. The book will be of particular interest to interaction designers, visual designers, software engineers, and human-computer interaction experts.
