i-dentity: innominate representation as engaging movement game element

Movement-based games typically make it clear whose movement representation belongs to which player. In contrast, we argue that concealing whose movement controls which representation can be a resource to facilitate engaging play experiences. We call this "innominate movement representation" and explore this opportunity through our game "i-dentity", where participants have to guess which player makes everyone's controller light up based on this player's movements. We report on participants' play experiences of i-dentity. With our work we hope to expand the range of digital movement games.
