Preliminary Study of the Interface

Twenty students who were registered in a systems development course served as the subjects for a preliminary usability test of the CASCADE interface. The test suite was designed to explore the features that are most frequently needed in real-world situations, e.g., comment generation, comment deletion, navigation through the document hierarchy and editing. Mouse button events and timing information were collected. In addition, users were interviewed after completing the series of tasks.
