Interaction Modeling - User State-Trace Analysis (12 Feb 2006)
Collecting and reporting user data without presenting cog-action relationships results in poor problem definitions. In fact, practitioners often present no relationship between observed user behavior and the claim that there is a problem. Usability problems are presented as user verbalizations such as ďI donít know what Iím supposed to do here.Ē Although there is a cognitive reason why the user has fallen into this apparent uncertainty state, that reason is seldom presented. Further, the relationship between an identified problem and the solution to fix it is often not provided. If we donít know why the behavior is a problem we canít design a good solution.
