An interactive graph visualization for handling cooperative design activity context

The context of a collective activity is characterized by all information produced during the activity. The comprehension of this context by each actor is essential for the success of the activity. The mediatization of this context in software requires the definition of its data representation, but also its visualization representation in a human machine interface. We propose here a network representation of this context and an interactive visualization of graph allowing each actor to have simultaneously a global and local perception of the context, to handle it with adapted navigation functions and to modify it with intuitive edition functions. These representation and visualization forms were implemented in the framework of an architectural design activity.
