Abstract
We present a scenegraph-based schema, the ContextMap, to
model context information. Locations with hierarchical
relations are the skeleton of the ContextMap where nodes of
people, objects and activities can be attached. Context
information can be collected by traversing the ContextMap.
The ContextMap provides a uniform method to represent
physical and social semantics for context-aware computing.
In addition, context ambiguity can be modeled as well.
