Beat Signer is Professor of Computer Science at the Vrije Universiteit Brussel (VUB) in Belgium and director of the Web & 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, 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. In addition to the representation, linking and storage of information, on the data level Beat’s team deals with the context-sensitive adaptation and cross-media transclusion of content. On the visualisation and navigation level they, for example, develop zoomable user interfaces, while multimodal cross-media interfaces are investigated on the human-information interaction level. His research team is interested in new cross-media document formats as well as innovative forms of human-information interaction that go beyond the classical WIMP metaphor and they have improved various forms of human-information interaction. Beat has a strong expertise in cross-media solutions that bridge the gap between paper documents and digital services or media types and was leading the development of various frameworks for multimodal and multi-touch interaction (Mudra), gesture-based user interfaces (iGesture), context-aware computing (CMT) as well as tangible and augmented reality.
