Research in human-computer interaction has resulted in the development of task-theoretic analytical models that allow interface designers to evaluate the interface design on paper before building a prototype. Despite the potential of such models to reduce interface development costs and improve design quality, they are not widely used. We believe that the complexity of these models is the main impediment and propose a computer system to remove this obstacle. The proposed system enables interface designers to describe an interface design formally and then assess it in terms of usability dimensions such as ease of learning and ease of use. It facilitates and structures task analysis and spares designers the burden of learning the complex syntax of analytical models. This paper describes the proposed system and discusses an empirical study designed to evaluate it. The empirical results show that the proposed system improves the accuracy and speed of evaluation of interface designs and contributes to more favorable attitudes towards analytical models.
