CAIA 2011 is the successor of last year?s workshop (CAIA 2010) where a consensus was researched 
about defining assistance as a concept relative to a main task or purpose of a system or user.

This year we want to gain a more in-depth understanding of this definition of assistance in context
by studying interesting applications and investigating how far the definitions take us and how 
they should be refined or revised. We are especially interested in the interplay of context and 
assistance, as both are relative concepts. We invite researchers and practitioners in the fields 
of recommender systems, pervasive computing, mobile computing, urban sensing, social networking, 
context-aware systems, human computer interaction, or similar, working on Assistance Systems, 
either from an application centered or a theoretical point of view?to present their work at CAIA 2011.

Submission Details
*****************************************************************
Papers should be formatted according to the Springer LNCS guidelines. The length of each paper 
should be between 5 and 10 pages. All papers must be written in English and submitted in PDF format
via http://www.easychair.org/conferences/?conf=caia2011. Papers could (for instance) report on 
recent results, introduce new ideas as position papers or discuss interesting future research 
questions.

Publication options are currently evaluated.
We will probably offer a ?cite-able? online publication format.

At least one author of an accepted paper has to attend the workshop in order for the paper to be
