Services and products increasingly include interconnected computerized things with embedded sensors and displays. This trend is evident also in everyday objects and tools and is rapidly changing the way we live our lives. Design work and designers have to keep up with this development and adapt both thinking and tools. The problem is no longer just to design a physical object or interact with a single computational device. Design is not even limited to the service embedding the device. It needs to include all of the above while, importantly, also taking the particular context of use into account.
This book presents a framework and a number of tools from a systems perspective. It will help the designer take the step from designing a thing or a web site to designing a context aware pervasive service. To begin with three complementary interactors; Human, Information and Thing along with the interactions they enable are introduced. The model is used to infuse a way of thinking about pervasive services and their support. We will discuss several types of support ranging from networked infrastructure for communication to cognitive support by artificial intelligence.
The design process is introduced by a discussion on the goals for design. Usability, value based design and meaningful user experiences are surveyed as guides for better designs. From this understanding a design process is staged that is structured along the levels of service design, requirement analysis, conceptual, information, interaction, and appearance design. For each level relevant tools and an outline of the design spaces of mobile and pervasive applications are presented and the design work is framed by an overall story-based approach.
This second edition of the book contains more than 500 pages, 112 figures and 218 illustrations. New extensive sections on interior design and design of joint ventures have been added and both text and ideas have improved from the first edition. One year weiser.
