Accessibility

There's some interesting and useful work going on at the TechDis Web Accessibility & Usability Resource.  They also have a tool to support heuristic review -- their accessibility oriented heuristics are very nice.  In our our tool, uzReview, we're eliminating the need to print out the worksheet and allowing heuristic evaluation ratings to be tied to individual pages *or* workflow keywords.

Visualizing Aggregate Page Activity

Previous work in Uzilla led to topographical style and eye movement like "mouse fixation"  overlays on pages to denote multi-user activity at the page level.  For some general insights into page activity, a simpler graph may suffice.  The lines below represent  durations on page with the maroon bars denoting mouse activity time, the empty spaces pauses, and the final orange line indicates the time between the mouse resting and the page unloading.  Combined with drill down information overlays, this may prove a promising approach.

Due to the presence of heavy tailed distributions in task time and most short reaction time style measurments, this approach is a perfect candidate for a perspective wall approach. While perspective walls are generally used for focus/context, in this scenario it's simply an attractive design for nonlinear magnification. The perspective wall in this case is a mockup, but the standard version is almost available in Uzilla.net. A port to Flash will add the perspecting approach.
