You definitely want to get the scripts and install them ... that is most definitely what a blind person would do, as long as they know about them, and more and more do. Are you going to be doing a goms analysis on the use of jaws+scripts with visual studio and then on your tool? I think even a simple keystroke level modeling GOMS analysis might be quite telling, and I believe that Card, Moran and Newell introduced that technique in "The Psychology Of Human Computer Interaction", which is a book from over 25 years ago. It came out in 1983 according to some quick googling. At first, when you mentioned video taping it, I immediately thought of a cognitive JogThrough as introduced by Rowlands, D.E. and Rhodes, D.G. It, in my opinion, has a great deal of the benefit without some of the tediousness of a walk through, and I was wondering if you'll be using a similar technique? It's extremely time consuming though, even though it's faster than a walk through. Regardless, good luck.

The work I'm doing is a large component of my dissertation and actually includes a series of experiments and theoretical work. The next experiment is a little of both. We'll probably video tape folks using our tool for usability analysis, but take some quantitative measures to make our statistical analysis easier, I suspect. Some of the previous experiments use some pretty new theoretical techniques which are somewhat difficult to classify, and are based on trying to measure a human's comprehension of audio, which is somewhat tricky. Some of this is published, although I'm waiting to publish some of the major experiments until my dissertation is finished. I can email you one of the latest papers if you want, or if you have IEEE access, it was presented at ICPC 2007 this year.
