Abstract
Current context-aware services make the assumption that the context they are dealing with is correct. However, in reality, both sensed and interpreted context is often imperfect. In this paper, we describe an architecture that supports the building of context-aware services that assume context is imperfect and allows for the refinement of this imperfect context by mobile users in aware-environments. We discuss the architectural mechanisms and design heuristics that arise from supporting this refinement over space and time. We illustrate the use of our architecture and heuristics through two example context-aware services, an In-Out Board for the home and a situation-aware reminder tool.
