A Middleware-Based Application Framework for Active Space Applications

Manuel Román and Roy Campbell (UI Urbana-Champaign)

Ubiquitous computing challenges the conventional notion of a user logged into a personal
computing device, whether it is a desktop, a laptop, or a digital assistant.  When the
physical environment of a user contains hundreds of networked computer devices each of
which may be used to support one or more user applications, the notion of personal computing
becomes inadequate.  Further, when a group of users share such a physical environment, new
forms of sharing, cooperation and collaboration are possible and mobile users may constantly
change the computers with which they interact; we refer to these digitally augmented physical
spaces as Active Spaces. We present in this paper a middleware infrastructure that provides
mechanisms to construct, run or adapt existing applications to ubiquitous computing
environments. The infrastructure binds applications to users, uses multiple devices
simultaneously, and exploits resource management within the users' environment that reacts
to context and mobility. Our research contributes to application mobility, partitioning and
adaptation within device rich environments, and uses context-awareness to focus the resources
of ubiquitous computing environments on the needs of users.
