KAIST (Wonder Lab)
Nowadays, it is easy to find concepts for connecting mobile devices and looking at photos together. Despite the increasing interest in multi-device single display groupware (multi-device SDG) today, most of the existing research is limited to using a rectangular form array to enlarge the display. In this paper, we suggest a new way of assembling mobile devices to create unique forms, such as rings, bars, and radial displays, and to develop three games with them. During the development process, we conducted generative workshops to understand the inter-device interaction characteristics of the uniquely formed multi-device SDG. Directionality, inter-device space, and tangible interactions were extracted from the workshop. Through a user study of the developed games, we refined the characteristics and found additional design issues: sitting and ownership. The inter-device interaction characteristics and issues of multi-device SDG obtained from this study could be generally applied to collocated multi-mobile interactions.
