Proxemic Interactions envision interactive computer systems that exploit peoples’ and devices’ spatial relationships (proxemics) to provide more natural and seamless interactions with ubicomp technology. It builds upon fundamental proxemic theories about people’s
understanding and use of the personal space around them. In this paper, we focus on how nuances of the proxemic theories and concepts of Proxemic Interaction can be applied to address six key challenges of ubicomp interaction design, where we consider how we can leverage information on fine grained proxemic relationships. We also discuss how previous proxemic aware systems addressed these challenges.
