Usability Evaluation of Interactive Systems using TREVIS
Michael Ha hnel, Nico Hamacher, Karl–Friedrich Kraiss · 2002
While the usability of interactive systems is getting increasing attention, the designing engineer has to evaluate the specifications and implementations of the developed system. To support these evaluation throughout all phases of the whole development process the tool TREVIS is being implemented and will be described in this paper. Based on the GOMS-theory TREVIS uses formal, normative models to predict measures to estimate the usability of the examined system. It supports the engineer with building these models either manually or automatically and analyses these models as well as empirical obtained action logs.
