Usability testing typically focuses on methodology and metrics, while the specific interactions being tested are chosen in an ad hoc way. This paper demonstrates a framework for organizing interaction scenarios for l user interfaces (GUI). The framework is an adaptation of the two-dimensional abstraction hierarchy introduced by Rasmussen [1] in which an interaction consists of a purpose, functionality, and form. Interactions for a GUI are organized into four main categories, with numerous subtasks. The four main categories determined are 1) object manipulation, 2) content manipulation, 3) view manipulation, and 4) information presentation. The general framework can guide evaluators in choosing key interaction scenarios for GUI applications across a diverse array of user capabilities.
