History of Interaction Design

Marc Rettig is amazing. His history of interaction design (3.3mb pdf) is still something I'm unpacking (and will be for a couple more weeks).

At the core is the progression of interaction design as a practice focused on operating the machine, to using the software, to accomplishing a task, to pursuing experience, to making connections, and (in the future) to dynamically enabling opportunities. Along the way, he offers areas of concern for interaction design, from strategy to screen design. And he offers a model for user experience. All in one densely packed presentation. It's worth the download, even on dialup. (thanks PeterV)
