Con-textual navigation support

Abstract

The exponentially increasing amount of information being made available world-widely through a basic form of hypertext technology creates problems and opportunities for advancing the state of the art in human-machine interaction. The major problem for users is to find their way in this heterogeneous hyperspace and to quickly access the information they need, the major opportunity is the connectivity and interactivity between a substantial population and a considerable amount of resources and knowledge. In this paper we present, through an example application, a novel way of supporting the user of a WWW application. The approach is novel in that we generate a context-sensitive meta-text to serve as a navigation guide for an existing application (rather than to make the application itself user adaptive) and that we use a very dynamic user model, trying to capture the user's minute-to-minute evolving context. We finally discuss how the foundations of this approach fit into a radically new way of supporting humans in information-rich real-world situations, called co-habited mixed reality.
