Better Living Through Geometry

Mark Weiser described ubiquitous computing as, "invisible, everywhere computing that does not live on a personal device of any sort, but is in the woodwork everywhere." [8] The EasyLiving project at Microsoft Research is focused on those aspects of ubiquitous computing relevant to smart environments, including work in distributed computing, geometric world modeling, computer vision, and user interfaces. Though the need for research in distributed computing, perception, and interfaces is widely

This paper introduces three scenarios which benefit from geometric awareness, examines three existing mechanisms for providing geometric knowledge, and then describes the EasyLiving Geometric Model. In particular, the focus is on improving the user experience of systems which are comprised of many independent devices and heterogeneous perception technologies.
