The rapid development of mobile communication networks and the
availability of miniaturized and inexpensive sensor technology allow
for the development of multifunctional mobile devices that are able
to collect and communicate context information. We also currently
see a clear trend towards the integration of embedded systems
including sensors into ßmart" everyday things, which is also
referred to as Ubiquitous Computing. The deployment of sensor
technology allows for so-called context-aware applications, going
far beyond of providing mobile access to information and computing
resources. Context-aware applications exploit captured sensor
information to adapt to the current situation of mobile users. For
instance, the information offered to a user may depend on his
current location, and the way how it is presented to him may depend
on the speed he moves, whether he is on its own or with others, and
so on.
In this paper, we characterize context-aware applications and
present the vision of a digital world model as the foundation for
this class of applications. Further, the paper discusses the
benefits and reseach challenges associated with digital world
models, which allow applications to take into account the state of
the real world and react to state changes.
