WORKSHOP SCOPE
The rapid rise of online social communities has created a new paradigm
for personal networking. Web based platforms currently attract large
numbers of users. Twitter states to have more than 100 million users with
a rate of 300,000 new users signing up per day. Facebook even counts more
than 400 million active users these days.
In a logical and rapid progression many social communities are now going
mobile, using smartphones or other wireless devices in addition to or
instead of the PC. A recent comScore study revealed that in 2009 already
30% of smartphone users accessed social networks via their mobile devices.
Twitter mobile usage grew by 347% in this year while Facebook mobile usage
was up 112% thus showing an almost exponential growth. Another trend is the
rise of special mobile location-based and proximity-based social networks
like Foursquare where users explore the real world connected to and aided
by the social network.
As a result, online social communities become pervasively accessible
providing a platform for manifold communication and interaction with
network contacts both in real-time and non real-time. For instance in
Facebook people interact with over 160 million objects like pages, groups
and events and there are more than 25 billion pieces of content shared each
month. Typical collaboration features include real-time chat, map-based
interaction, notifications about friends’ activities, proximity alerts, or
even augmented reality games. Thus, collaboration and social networking
functionality is more and more tied together and creates a new social
interaction experience for the participants. This experience becomes more
and more pervasive since social networking platforms and applications are
available on a large set of computing devices.
The aim of the PerCol workshop is to bring together researchers from the
three areas of mobile and pervasive computing, social networking, and
collaboration to explore the research challenges, potentials and business
perspective of future pervasive interaction based on social networking
technology. Our primary goal is to foster communication and collaboration
across these disciplines to enable interdisciplinary research. Thus,
contributions targeting at least two or even all of the three areas are
highly encouraged. Nevertheless we also encourage authors who are specialists
in one of the three areas and have a keen interest in broadening their view
to present their work and to discuss how it can benefit from the related
research areas.

Topics of interest to the workshop include (but are not limited to):

- Social pervasive content sharing and live media distribution
- Pervasive presence, awareness and instant messaging
- Shared viewing and shared editing on mobile devices
- Novel types of collaboration in social networks
- The role of location and proximity for social software
- Security aspects of pervasive social networks
- Linking the physical and the virtual world
- Augmented reality games
- Real-life use case experiences (e.g., pervasive health care)
- Business relevance and potentials for enterprises
- The role of sensors for pervasive collaboration/social networking
- Energy efficient and mobile enabled protocols
- Software engineering challenges of pervasive social networks

PAPER SUBMISSION AND PUBLICATION
Submitted papers must be unpublished and not considered elsewhere for
publication. Also, they must show a significant relevance to the
workshop topics of communication, collaboration and social networking in
pervasive computing.

All papers should be in IEEE 8.5x11 conference format. Papers will be
limited to 6 pages. Submitted papers will undergo a rigorous review
process handled by the Technical Program Committee. Accepted papers will
appear in the PerCom'11 Workshops proceedings published by IEEE Computer
Society Press.

Please note that all accepted papers need to have a full registration to
the conference (there is no workshop only registration). No-shows of
accepted papers at the workshop will result in those papers NOT being
included in the IEEE digital libraries.

IMPORTANT DATES
Papers due by: October 15, 2011

Final papers due to IEEE: January 27, 2012
