CANVAS is a software product from VasSol, Inc., which uses input from MRI scanners to create 3D models of a patient’s vasculature and accurately calculate blood flow. This case study reports on a nine-month effort to turn a prototype into a commercial product. The authors derived high value from small amounts of field research, by using a series of semi-formal analysis techniques. One key concept was that of “alignment ” – clearly connecting functionality with interface, and these in turn with the needs at each step of the task. This is a basic idea, but difficult to achieve for a complex feature set and complicated task. The final product is built around a small set of views, around which all controls are grouped. It makes the task and work flow explicit in the interface, and provides a “complexity gradient ” in which more complicated controls are revealed as the user faces more difficult challenges.
