Context aware computing devices and methods

摘要

Context-aware computing systems and methods are described. In particular embodiments, location aware systems and methods are described. In at least some embodiments, hierarchical tree structures are utilized to ascertain a device context or location. The tree structures can be stored on or accessible to mobile computing devices so that the devices can determine their own particular context or location. A computing device can automatically determine its context or location by ascertaining a node on one or more of the tree structures and then traversing the tree structure to ascertain the complete context.
