Abstract
The current set of temporal operators is insufficient to make effective use of task models as specifications for user interfaces. Moreover, the predominant monolithic task tree structure does not scale well for sizable applications. In order to overcome these shortcomings, a small collection of practical extensions for task models is proposed. In particular, we define new temporal operators (stop, non-deterministic choice, deterministic choice and instance iteration), concepts in support of modularization and a high-level task diagram notation. Finally, we introduce a new concept for expressing cooperative task models that distinguishes between different roles as well as between actors fulfilling these roles.
