This volume constitutes the revised papers of the 5th European Conference on Smart Sensing and Context, EuroSSC 2010, held in Passau, Germany, in November 2010. The 13 revised full papers were carefully reviewed and selected from numerous submissions. The papers address topics such as applications; sensing; systems support; and higher level modeling. In addition to the Conference is a short report about the Workshop on Ambient Assisted Living (AAL) Platform included.
