Abstract. The use of context is important in interactive applications. It is par-
ticularly important for applications where the user's context is changing rap-
idly, such as in both handheld and ubiquitous computing. In order to better un-
derstand how we can use context and facilitate the building of context-aware
applications, we need to more fully understand what constitutes a context-
aware application and what context is. Towards this goal, we have surveyed
existing work in context-aware computing. In this paper, we provide an over-
view of the results of this survey and, in particular, definitions and categories of
context and context-aware. We conclude with recommendations for how this
better understanding of context inform a framework for the development of
context-aware applications.
