Contextual ConcurTaskTrees: integrating dynamic contexts in task based design

Abstract

Much research has been done on how context can be gathered and how the task of harvesting the context information can be made as easy as possible for application developers. However less research has been done on how to design a system that adapts to the context while being active. This paper presents Contextual ConcurTaskTrees, a notation that combines the specification of dynamic context and tasks. The effect of the integration of the new notation on a current task-based approach is demonstrated and discussed. Special attention is paid to how the context is integrated and which parts of the context can be specified using the presented notation.
