A Framework for Developing Pervasive Cross-Media Applications based on Physical Hypermedia and Active Components

Presentation given at ICPCA 2008, 3rd International Conference on Pervasive Computing and Applications, Alexandria, Egypt.

ABSTRACT: We present a framework that supports the development of pervasive cross-media applications through a clean separation of interaction design and application programming. The approach is based on a novel concept of active components that provides a lightweight mechanism for linking physical and digital entities to services. We show how the development of cross-media applications can be simplified by adopting an authoring rather than a programming approach and how we achieved this by integrating the active component concept into an extensible hypermedia server.

    ▪ Writing as a collaborative act of memory and story- telling ▪ Reading, writing and narrative as an act of making sense ▪ Handwriting as a tool for human computer interaction In collaboration with Axel Vogelsang, Artists in Labs Programme
  9. ICPCA 2008, October 7 Beat Signer, [email protected] Conclusions ▪ Separation

    of interaction design and application programming ▪ Authoring rather than programming approach ▪ Extensible cross-media framework ▪ modular and extensible active components ▪ resource plug-ins ▪ Rapid prototyping
