Abstract
Post-it notes are a popular paper format that serves a multitude of purposes in our daily lives, as they provide excellent affordances for quick capturing of informal notes, and location- sensitive reminding. In this paper, we present Move-it, a system that combines Post-it notes with a technologically enhanced paperclip to demonstrate how a passive piece of paper can be turned into an "active" medium that conveys information through motion. We present two application examples that investigate the applicability of Move-it sticky notes for ambient information awareness. In comparison to existing notification systems, experimental results show that they reduce negative effects of interruptions on emotional state and performance, and provide unique affordances by combining advantages of physical and digital systems into a novel active paper interface.
