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. |
