Abstract

This paper describes a heuristic creation process based on the notion of critical parameters, and a comparison experiment that demonstrates the utility of heuristics created for a specific system class. We focus on two examples of using the newly created heuristics to illustrate the utility of the usability evaluation method, as well as to provide support for the creation process, and we report on successes and frustrations of two classes of users, novice evaluators and domain experts, who identified usability problems with the new heuristics. We argue that establishing critical parameters for other domains will support efforts in creating tailored evaluation tools.
