A fascinating read for anyone interested in the history of interaction design in particular and design thinking in general. Moggridge interviews leading design practitioners, resulting in a diversity of opinions about what constitutes good design. In the last chapter, “People and Prototypes,” the author describes the process he followed to design the first laptop computer, the GRiD Compass, and countless products since.

For Moggridge, the design process involves synthesizing the best solution within the constraints imposed by technology, culture and business goals. The process is as much an art as a science, which is probably why the field appeals to people with a wide range of education and experience. Designing Interactions ships with a DVD containing videos of the interviews conducted for the book.
