Abstract

Task models are widely used within the research field of HCI for the model-based development of interactive systems. Recently introduced approaches applied task models further to model the cooperative behavior of people using devices within a smart environment. We describe a method of model-based usability evaluation to evaluate interactive systems, with a particular focus on smart environments, which are developed based on task models. We consider the evaluation in early development stages to interactively walk through the models and in later stages to execute a test case within a real environment. The paper provides results of a prototypical implementation.
