A location and tracking system becomes very important to our future world of pervasive
computing, where information is all around us. Location is one of the most needed
information for emerging and future applications. Since the public use of GPS satellite is
allowed, several state-of-the-art devices become part of our life, e.g. a car navigator and a
mobile phone with a built-in GPS receiver. However, location information for indoor
environments is still very limited. 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.
Using Radio Frequency Identification (RFID) tags is a new
way of giving location information to users. Due to its passive communication circuit, RFID
tags can be embedded almost anywhere without an energy source. 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. 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, a user’s destination, and a routing server where the shortest route
from the user’s current location to the destination. The navigation device communicates
with the routing server using GPRS networks. We build a prototype based on our design
and show some results. We found that there are some delay problems 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
This System having three different modules,
1) Blind RF-ID Module
2) Room RF-ID Tag Unit:
3. IR TX Sensor for Object Type and Range Sensing Unit
Always this unit will transmit the IR Object ID-Code through RC5 Protocol by 38KHZ frequency.
1. Blind RF-ID Module
This is divided into two different modules,
b) IR-RC5 Protocol
c) PIR –Human Detect
Advantage of these Systems:
1) Automation of all CUSTOMER to communicate through remote GSM using mobile
2) Save data using automatic control systems
3) Less cost to communicate
4) Less power to automate
5) Increase Safty
6) To increase n number of person to communicate and automate.
7) Easy and fast identification system
1) This system will support less distance.
2) It won’t Sense Long Distance object.
1) This system will support all type of object to identify the blind.
2) Less cost
3) Signal will support all places.
5) Wireless communication
6) It won’t affect any other defects of human being.
7) The blind will not depends the help from any others.
