Research of region navigation based on Radio Frequency Identification

Orientation, occasion and mobility for visually impaired people is very difficult, especially in unknown environment. This paper describes an embedded pedestrian navigation system contained sensor that is an active Radio Frequency Identification (RFID) tag system. The navigation system based on active RFID is a new identification technology, judging direction and position of user by calculating in the tag net. Practices of experimental prove that the system has good reliability, higher precision and various functional selections.
