Digital technology has changed the way we interact with everything from the games we play to the tools we use at work. Designers of digital technology products no longer regard their job as designing a physical object—beautiful or utilitarian—but as designing our interactions with it. In Designing Interactions, award-winning designer Bill Moggridge introduces us to forty influential designers who have shaped our interaction with technology. Moggridge, designer of the first laptop computer (the GRiD Compass, 1981) and a founder of the design firm IDEO, tells us these stories from an industry insider's viewpoint, tracing the evolution of ideas from inspiration to outcome. The innovators he interviews—including Will Wright, creator of The Sims, Larry Page and Sergey Brin, the founders of Google, and Doug Engelbart, Bill Atkinson, and others involved in the invention and development of the mouse and the desktop—have been instrumental in making a difference in the design of interactions. Their stories chart the history of entrepreneurial design development for technology.
