An Rfid Application For The Disabled: Path Finder

RFID technology that is being used since World War II has got such much cheaper that it is possible to see applications from health sector to retail depending on that technology. Path finder, of which it is designed for the mainly the blind, is an RFID based application which stems from nonexplicit requirements and aims for user group to reach the target within a nonfamiliar or totally unknown campus area without taking any help outside. Starting from the entrance gate, application guides the user until wherever the user want to reach and in vise versa direction. During the trip, may user decide to change the target, application directs the user to new target by using a shortest path algorithm. In this paper, we tried to explain how to develop such a solution and gave test results of the system.
