Preface
This year marks the third edition of EuroSSC. It builds on the success of the
pasteditions,heldinEnschede,The Netherlands in2006,andinKendal,UK in
2007.On behalf of the OrganizingCommittee, we would like to welcome you to
EuroSSC 2008, in Zurich, Switerland. This volume contains the invited papers
and technical peer-reviewedpapers selected for presentation at the conference.
At EuroSSC we aim to explore technologies, algorithms, architectures, pro-
tocols, and user aspects underlying context-aware smart surroundings, cooper-
ating intelligent objects, and their applications. Since its inception, EuroSSC
has taken a complementary technology-driven and user-driven view to discuss
these aspects. It is one of the particularities of EuroSSC, and the 2008 edition
madenoexception.Inadditionweemphasizedaspectsrelatedto qualityofcon-
text and context-aware feedback by actuator systems. This reflects the growing
importance that context processing in uncertain environments and sensor and
actuator networks take in ambient intelligence environments.
We received 70 paper submissions. They originate from 30 countries of Eu-
rope, the Middle East and Africa (66%), Asia (22%), North America (9%), and
South America (3%). These numbers reflect the European origins of EuroSSC,
but also show that EuroSSC is a recognized and attractive platform for partici-
pants from all regions of the world.
The review process was double-blind. This ensured that the papers were
selected purely on their technical merits. Each paper received a minimum of
two reviews, with most receiving three reviews and some four. On the basis of
the peer reviews,the ProgramCo-chairsselected17papers for publication.The
25% acceptance rate indicates the high quality of the papers included in this
proceedingsvolume.The paperswereselectedaccordingtotheir technicalmerit
toexemplarilydiscussthekeythemesaddressedbyEuroSSC:sensorsandsignal
acquisition; context inference; high-level context processing; and applications
and scenarios.
WeinvitedAlainCrevoisier,researcherattheUniversityofAppliedSciences,
Yverdon, Switzerland, to give an invited paper presentation. Sensing being the
first requirement of context-aware systems, he discussed how daily life objects
can be turned into tactile interfaces, on the basis of his activities in the de-
velopment of new musical instruments, notably within the EU-funded research
project ‘Tangible Acoustic Interfaces for Computer–Human Interaction’.

This year saw a 35% increase in paper submissions since the last edition. We
are satisfied to have received contributions from both Americas, and a steady

and the increased diversity in the countries of origin (30 countries in 2008, 21
in 2007)shows that the conference has grownmore attractive.We are confident

that 2008 will be a successful milestone that will lead to future editions equally
(and more!) successful.
A peer-reviewed conference cannot exist without a community supporting
it. As a conference is a place to share and discuss ideas, we would first like to
thank all the 179 authors who took time to write and submit papers. We are
extremelygratefulto the ProgramCommittee andthe additionalreviewerswho
dedicated a lot of their valuable time to read, comment, rate and suggest ways
to improve those papers. The peer-reviewing process is time consuming, but
it is essential to ensure high-quality publications, and to provide constructive
feedback and advice for the papers that could not be accepted. We would like
to thank the authors of accepted papers for revising their papers according
to the reviewers’ comments. We hope the review process helped those authors
whose paper could not be accepted. In order to provide an opportunity for
these authorsto presenttheir work,we organizeda poster paper session,with a
delayed submission deadline, published in an adjunct proceedings with its own
ISBN number.
We are thankful to the supporting organizations that helped us with Eu-
roSSC: the Institut fu¨r Elektronik and ETH Zu¨rich that supported this confer-
encebyprovidingtheinfrastructure,theSpringerLNCSstaff,theIEEECommu-
