Visible signage equivalency could be achieved overnight. Further, Interface, Inc., a commercial floor manufacturer is now adhering RFID tags to the protected underside their 50X50 cm floor tiles. Using such flooring and the new long-range readers, a very elegant and affordable indoor GPS-like guidance system can be realized through triangulation of these RFID floor tiles. In the long run, as this RFID flooring infrastructure fills in, the most ideal solution could result, as it would enable the development of easily-managed building databases containing everything users would need to know to orient to new buildings and find their way around with ease. Users would never be lost, as they would always know their current location and heading. In addition, such a building database would be much easier to maintain, as opposed to updating individual RFID tags, when building tenants move or renovations take place. Interface is very interested in supporting our research, and is donating 2500 square feet of their RFID flooring to the VA for this purpose.
