Nexus is an interdisciplinary research center in the fi eld of mobile context-aware systems
and applications at the University of Stuttgart, funded by Deutsche Forschungsgemeinschaft
(DFG) since the year 2003. Th e research program of Nexus integrates
a wide range of disciplines, like Computer Science, Geoinformatics, Industrial Manufacturing,
and Philosophy of Science and Technology. Nexus is headed by Prof. Rothermel
from IPVS and consists of 17 research projects including 6 projects from
IPVS (see Section 2.5 for a detailed description of the individual projects). Research
on globally federated context models constitutes the scientifi c core of Nexus, enabling
our vision of a “World Wide Space” – an open system where partial context models
from diff erent providers are integrated into a global and highly detailed spatial world
model.

An important research focus of the current funding period is quality of context.
As part of this research eff ort Nexus organized the First International Workshop on
Quality of Context (QuaCon 2009), which aimed to bring together researchers from
various fi elds to discuss the diff erent facets of context quality and to make a consolidated
contribution towards an integrated way of treating them. Th e workshop attracted
