David was my student in a previous RHE 330c, which at that time was a course on contextual design. I didn't know this, but apparently my class was a turning point for him: he came in as a Flash programmer, and exited as a budding UX designer. The new line of work was more interesting to him, but it also boosted his salary by 20%. UX is a big deal now, he told us, and he was kind enough to describe a case study.
I was especially interested in how he moves from paper prototyping to wireframes, then to rapid prototypes (clickable wireframes). He also interacts with graphic designers at this point, handing the wireframes off for visual refining.
David gave me permission to post his slide deck here. It's a nice introduction to the UX process with several of its techniques.
