Abstract
A system (100) and method (300) of using a context vector and database (202) for location applications can include a transceiver (104), a plurality of environmental sensors (114, 116, 118, 120, 121) including at least two location technology devices (110, 112), and a processor (102) coupled to the transceiver and the plurality of environmental sensors. The processor can be programmed to sense (302) an environmental condition for a given location, define (310) a context vector for the given location, detect (312) a context transition corresponding to a change in the environmental condition, and modify (314) an operation of the at least two location technology devices based on the context transition detected. The processor can be further programmed to form (320) a new context vector based on the context transition and attempt to match the new context vector with a pre-stored context vector.
