I-dentity

Research Background Movement-based digital games typically make it clear whose movement representation belongs to which player. In contrast, we argue that selectively concealing whose movement controls which representation can facilitate engaging play experiences. We call this "innominate movement representation" and explore this opportunity through our game "i-dentity", where players have to guess who makes everyone's controller light up based on his/her movements. Our work reveals five dimensions for the design of innominate movement representation: concealing the association between movement and representation; number of represented movements; number of players with representations; location of representation in relation to the body and technical attributes of representation. We also present a set of strategies for how innominate representation can be embedded into a play experience. With our work w expand the range of digital games. Research Contribution This work contributes to understanding game and interaction design for social and physical play. Drawing inspiration from research on ubiquituous computing, embodied interaction and games, this research introduces the concept of innominate representations for digital bodily play Research Significance The significance of this research is attested to by the following indicators: its being presented (Long Paper), exhibited (Interactivity) and is a finalist for the Student Game Competition at the ACM SIGCHI Conference on Human Factors in Computing Systems (CHI 2014 Proceedings and Extended Abstracts, Toronto, Canada) (peer-reviewed, 22.8% acceptance rate, previously ERA A ranked); and has been presented (Long Paper) at the ACM Conference on Interactive Entertainment (IE 2013 Proceedings, Melbourne, Australia). It has also been featured in the official ACM CHI 2014 promotional trailer at http://chi2014.acm.org/, which has been watched by over 5,000 people on youtube at http://www.youtube.com/watch?v=iN1wLizrsKY
