Preface
This book reflects on the significance and design of embodied interaction with digital information and artifacts. We are experiencing a transition from traditional modes of interacting with computing devices in which we are typically sitting still and moving our fingers on a keyboard to large body movements to effect changes and engage with digital information and artifacts. As designers we are challenged not only by the increasing range of technologies that enable interaction design, but also by the range and focus on human-centered design methodologies. Engineering design starts with requirements derived from human needs but necessarily has a focus on the design of the system so that it satisfies those requirements and optimizes performance of the system. In contrast, in interaction design, the human is inherent to the system and therefor the focus remains on human needs, desires, and abilities throughout the design process. Along with this focus on people during the design of interactive systems, there is an
