RFID-Based Road Guiding Cane System for the Visually Impaired

The RFID-based road guiding cane is a navigation system especially designed for the visually impaired. Geographic location, traffic light signals, and business information are saved in a series of RFID labels constructed beneath the sidewalk. With the road guiding cane reading the RFID labels, the visually impaired can locate themselves, be aware of traffic light signals, and find business information near them on the road. After users set the destination, the cane automatically directs the routes for users via voice by specifying the current location and keeping track of previous locations. Compared with the Global Positioning System, the RFID-based road guiding cane system is more reliable, more accurate, cost-saving, and versatile in providing precise location-based services for the visually impaired.
