Research of navigation and positioning at local area based on RFID

Recognition of orientation, occasion and mobility for visual 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. Test results show that the positioning and navigating achieved by the method is effective at a local region area.
