Deriving presentations from task models

Most task-based approaches have been used to analyse and design the dialogue part of interactive applications. There has been less focus on how a task model can be used to derive systematically indications for the design of the presentation of a user interface. This paper presents a solution to this problem which is based on identifying the sets of tasks that are active during the same period of time, and rules that take into account the semantics of the tasks considered and their relationships.
