Reformulating clancey's generic tasks for bridging both sides of dual reality

Abstract

In many domains, the realization of an abstract model implies to cross the valley separating an abstract conceptualization and its actual completion in the physical world. In this paper, we propose a generic model based on Clancey's ontology of generic tasks and the dual reality paradigm. This model aims at bridging the real and the virtual sides of dual reality in the generic context of task/project realization. We describe existing implementations of the model, focusing on tangible tabletops -a medium particularly well suited to blend the real and the virtual worlds in a consistent tangible environment. Discussion, perspectives and conclusions are then presented.
