Beat Signer is Professor of Computer Science at the Vrije Universiteit Brussel (VUB) in Belgium, where he is director of the Web and Information Systems Engineering (WISE) laboratory. With his team he is investigating cross-media information spaces and architectures (CISA) and their use in information science, interactive paper, dynamic data physicalisation and tangible holograms, augmented reality as well as multimodal and multi-touch interaction frameworks. Thereby, they are developing innovative ways of representing and linking pieces of information across digital and physical information spaces based on the resource-selector-link (RSL) hypermedia metamodel.
