Ubiquitous environments are important because they allow users to move
about freely and continue the interaction with the available
applications through a variety of interactive devices (including cell
phones, PDA's, desktop computers, digital television sets, and
intelligent watches). A frustrating limitation is that people have to
start their session over again from the beginning at each interaction
device change. This book reports results based on the work in the OPEN
project. It provides solutions able to address three key aspects: device
change, state persistence and content adaptation. There is a lack of
migratory services technology for the migration of applications in
different usage scenarios. This book offers a general and open migratory
service platform solution based on a sound and innovative scientific
approach developed by a multi-disciplinary consortium combining the
expertise of three technological world leaders, three well-known
research organizations and one SME.
