Tangible Interfaces for Art Restoration

Few people experience art the way a restorer does: as a tactile, multi-dimensional and ever-changing object. The authors investigate a set of tools for the distributed analysis of artworks in physical and digital realms. Their work is based on observation of professional art restoration practice and rich data available through multi-spectral imaging. The article presents a multidisciplinary approach to develop interfaces usable by restorers, students and amateurs. Several interaction techniques were built using physical metaphors to navigate the layers of information revealed by multi-spectral imaging, prototyped using single-and multi-touch displays. The authors built modular systems to accommodate the technical needs and resources of various institutions and individuals, with the aim to make high-quality art diagnostics possible on different hardware platforms, as well as rich diagnostic and historic information about art available for education and research through a cohesive set of web-based tools instantiated in physical interfaces and public installations.
