As a member of the European Paper++ and PaperWorks projects, Beat developed the interactive paper (iPaper) framework for integrating paper and digital services and information. Different solutions for innovative forms of interactive paper document publishing have been realised and the iPaper framework has been applied in a variety of applications including PaperPoint, EdFest, Generosa Enterprise, the Lost Cosmonaut, Print-n-Link, PaperProof and other solutions. We also recently released iGesture a general framework for gesture recognition under an open source license. Based on the experience that we gained from realising the interactive paper applications, Beat is currently investigating general design patterns and paper widgets for the new type of paper-digital user interfaces.
More recently, Beat started to extend the RSL metamodel, to deal not only with navigational cross-media linking, but also enable the structural representation of new forms of cross-media documents and information spaces. Furthermore, the open source iGesture framework is currently extended to support new types of gestures (e.g. 3D gestures).
Beat Signer studied Computer Science at ETH Zurich and did his Diploma Thesis (M.Sc.) in the Global Information Systems group. In his diploma project, he developed an object-oriented GUI for the object model multi-user extended file system (GOMES). A remote object mechanism was designed based on XML-RPC and employed in order to communicate in a machine and programming language independent manner allowing the Java-based GOMES application to use the whole functionality of the extended file system implemented in Oberon. He finished his PhD thesis on fundamental concepts for interactive paper and cross-media information spaces in August 2005.
