Knowledge-Based Usability Evaluation For Reality-Based Interaction

The great variety of new (Post-WIMP) interaction styles make them difficult to evaluate and compare. We propose a new evaluation method for them, Knowledge-Based Usability Evaluation (KBUE), that is based on similar ideas to those that drive cognitive architectures, such as ACT-R and Soar. We present KBUE as a way to formally specify the knowledge in the environment and in the user’s head, and how this specification can be used to examine whether the aforementioned set of knowledge covers the required knowledge for the performance of a task in a user interface. We believe that by using this specification, it becomes easier to evaluate and compare Reality-Based interfaces. Author
