The 2nd International Workshop on Location- and Context-Awareness
(LoCA) follows from the well-attended and enlightening 1st LoCA. The
list of papers to be presented in talks at this year's LoCA is
below. They span low-level sensing of location and context to
higher-level issues including privacy, representations, social
context, and mapping.

Our selective peer review process (24% acceptance rate) resulted in a
high quality group of papers that we anticipate will make for an
illuminating workshop on the issues of location and context. The
papers will be published by Springer.

LoCA is being held on May 10-11, 2006 at IBM Dublin in cooperation
with Pervasive 2006, which will be on May 7-10. Registration for LoCA
is open now at

http://loca2006.context-aware.org/

LoCA early bird registration is available until March 17th.  Note that
registration for Pervasive is open at http://www.pervasive2006.org/
