Libraries : comparisons between the real and the virtual in 3 D , 2 D zoomable and 2 D arborescent

The HyperVise project tries to facilitate the access to the large-scale digital libraries. One of its axes of research consists in listing some methods of research that exist in the real libraries and make defect in the virtual ones, and try to transfer them. Among these methods, we are especially interested in research by proximity and to the fortuitous and haphazard finding. To value the capacity to transfer knowledge (from the places and from the methods of researches) between the real and the virtual world, an experimentation is currently in progress. It consists to create a 3D and 2D models of a real library (the one of the school of Mines of Nantes) and to verify if a person knowing well the real library reuses this knowledge efficiently on a similar virtual environment, 3D or 2D.
