Abstract. A proposal for describing Just-UI patterns using a task oriented notation (ConcurTaskTrees) is presented. This work provides a method to convert a given pattern into a task tree and the contrary, to detect Just-UI patterns in task models. This bridge makes it possible to establish links between concepts from one model to the other one.
