Abstract
PerCom celebrates its ninth edition. During the past years, PerCom has become the premier event for the pervasive computing research community. The PerCom Work-in-Progress (WiP) session has been introduced for the first time in 2006 in order to present and discuss emerging results, novel research questions, approaches, and directions. Specifically, the aim of the WiP session is to provide a forum for early feedback on ongoing research and for discussion of novel, controversial, and thought provoking ideas.
