In this paper we present a new approach to the automation of usability evaluation for interactive systems. Design ideas or complete systems are modeled as a conditional state machine. Then, user interactions with the system are simulated on the basis of tasks, by first searching for possible solution paths and then generating deviations from these paths under consideration of user groups and system attributes. The approach has been implemented into a workbench which supports the modeling of the system and the evaluation of the simulations. We present first results for the reliability of the approach in modeling interactions with a spoken dialog system.
