System and method for navigating using multiple modalities

摘要

A system for navigating includes an interface operable to receive position information of a first modality. The position information of the first modality is associated with a navigation unit. The interface is further operable to receive position information of a second modality. The position information of the second modality is associated with the navigation unit. The system also includes a processor coupled to the interface and operable to identify a destination. The system is further operable to navigate to the destination based on the position information of the first and second modalities by switching between the first modality and the second modality.

1. A system for navigating comprising:
an interface operable to:
receive an identification of a destination inside a building;receive position information of a first modality comprising global positioning satellite (GPS) information, the position information of the first modality associated with a navigation unit; a processor coupled to the interface, wherein the processor is operable to:
determine directions from a current location of the navigation unit to the destination inside the building;detect that the navigation unit is within range of a radio frequency identification (RFID) network associated with the building, the building comprising a plurality of RFID tags; wherein the interface is further operable to:
receive RFID position information of the navigation unit; the processor further operable to:
navigate to the destination inside the building based on the GPS and RFID position information by automatically switching from GPS to RFID upon the detection that the navigation unit is within range of the RFID network associated with the building, wherein the processor utilizes GPS information outside the building and RFID information inside the building for the navigation; and wherein the processor is further operable to receive instructions to dynamically program one or more RFID tags of the plurality of RFID tags to transmit a user request to a navigation unit in the RFID network.
