Designing an interactive tactile relief of the meissen table fountain

Abstract

In this paper we highlight the practical experience gained during the first design iteration of a tactile relief for the Meissen table fountain exhibited at the Victoria & Albert Museum, London. Based on a 3D scan, we designed a 2.5D relief that is usable for our gesture-based interactive audio guide. We present a mixed-perspective view projection technique that combines the advantages of a top-down view and a frontal view, and developed a detail-preserving depth-compression technique to flatten less important parts. Finally, we present the results of a preliminary evaluation with 14 members of our participative research group, and give an outlook for improvements to be targeted in our ongoing research.
