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.
