I promised the participants in our workshop yesterday (hi! thank you all so much for a great workshop) that I'd post the bibliography to all the stuff I mentioned in class. Here it is (linked to Amazon):
Garrett, Jesse James, The Elements of User Experience (Jesse's diagram is available for free and he has built a site devoted to the book).
Snyder, Carolyn, Paper Prototyping
Tufte, Edward, The Visual Display of Quantitative Information
Kuniavsky, Mike, Observing the User Experience
Highsmith, Jim, Agile Software Development Ecosystems
Jeffries, Ron, et al, Extreme Programming Installed
My rough hand-drawn UI templates.
The Wiki William and I have been using to organize the class, which we'll be adding additional class resources to as we figure them out. Be warned, though, it's still pretty rough right now. It's mostly notes for ourselves.
