A decade of progress in interactive multimedia in museums forms the basis for papers on issues of systems design and user interface presented at the Fourth International Conference on Hypermedia and Interactivity in Museums (Le Louvre, Paris 1997). The papers selected for this volume focus on design (systems development and evaluation methodologies), interfaces (visitor aware systems and interactives providing geographical and chronological views of data), and case studies of museum multimedia ranging from collection catalogs to 3D environments.
