Abstract

Unified Modelling Language (UML) is rapidly becoming the international standard for software design notation and methods. However, it offers little or no support for the design of the user interface. Models and notations are required for describing user tasks and the structure of the human–computer dialogue to support these tasks. Lean Cuisine+ provides a notation for both dialogue and task modelling. This paper describes a method for the initial steps of interface design which incorporates both the UML and Lean Cuisine+ notations and provides a means of representing tasks in the context of the dialogue structure of the user interface.
