  Radio Frequency Identification for Pedestrian Navigational Assistance
  Posted on Wednesday October 22, @06:07AM Pacific
Net Devices University of Rochester researchers have come up with a unique and interesting use for the emerging radio frequency identification (RFID) systems. The Rochester team has reversed the standard radio tag setup by making the receivers mobile and the transponders fixed. Using this arrangement, information can be provided at certain points in space. The system, dubbed Navigational Assistance for the Visually Impaired (NAVI), can provide location information for the visually impaired and for other kinds of navigational assistance applications like self-guided tours.
