Context-awareness has become a distinguishing feature of Ubiquitous systems. Contrary to
desktop and web applications, Ubiquitous applications gather environmental context and
provide services without user intervention. In this paper, we propose a message-oriented
application model that is capable of modeling both user and system initiative interaction
paradigms. Systems designed based on this model are inherently loosely-coupled and
scalable. Results of this research include a systematic development procedure and its
supporting middleware. We show the feasibility of this model by constructing several
Ubiquitous applications for two dissimilar demo sites, and discuss experiences when adopting
this model.
