Beat Signer is Professor of Computer Science at the Vrije Universiteit Brussel (VUB) in Belgium, where he is co-director of the Web and Information System 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, mixed 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.
