The Research on Blind Navigation System Based on RFID

Based on the investigation about daily activity characteristics and modes of the blind, the study found that the main difficulties encountered in a trip of the blind included walking on the road, finding way, taking a bus and looking for usual life-arena. After analyzing the research and application of actual blind navigation technologies, to solve the demands and difficulties in the blind trip, the study presents a blind navigation system based on Radio Frequency Identification (RFID), wireless and mobile communications technologies. The system consists of RFID tag, portable reader which can be integrated into the blind cane, mobile phone, Call Center and center information servers. Using this system, the blind are able to know their location, condition of roads, vicinity buildings, and inquire about the optimal routes to their destination and available vehicles. The technologies used in this navigation system are mature, which ensures the system is practical, universal and with perfect function.
