4 Apr A Blind Navigation System Using RFID for Indoor Environments However, location information for indoor environments is still very limited as. In recent years, several approaches have been made to create systems that allow seamless tracking and navigation both in indoor and outdoor environments . We propose an RFID-based system for navigation in a building for blind people or visually impaired. The system relies on the location information on the tag.

In this article we propose a navigation system that uses RFID as blind navigation system using rfid for indoor environments main technology to guide people with visual impairment in unfamiliar environments, both indoor and outdoor, complementing the traditional white cane and providing information about the user’s geographical context. Several techniques are proposed to get location information in buildings such as using a radio signal triangulation, a radio signal beacon emitter, or signal fingerprinting.
The tag stores location information and gives it to any reader that is within a proximity range which can be up to 10—15 meters for UHF RFID systems.
A location and tracking system becomes very important to our future world of pervasive computing, where information is all around us. Advantage of these Systems: We propose an RFID-based system for navigation in a building for blind people or visually impaired.
Published by Elsevier B. Indlor Nowadays, navigation systems are widely used to find the correct path, or the quickest, between two places.

Due to its passive communication circuit, RFID tags can be embedded almost anywhere without an energy source. Several technologies have been proposed to make navigation inside of buildings possible. In the case of usinf environments, some hybrid systems have been proposed that use GPS as main information source and RFID for corrections and location error minimization.
Blind navigation system using RFID for indoor environments. We build a prototype based on our design and show some results.

Location is one of the most needed information for emerging and future applications. Procedia Computer Science Volume 27, Pages We found that there are some delay fod in the devices which are the communication delay due to the cold start cycle of a GPRS modem and the voice delay due to the file transfer delay from a MMC module.
