The Blind Interactive Guide System Using RFID-Based Indoor Positioning System

摘要

In this paper, we designed and implemented the Blind Interactive Guide System (BIGS) for the blind person to use in the building. The BIGS uses RFID-based indoor positioning system to acquire the current location information of the user. The system consists of two parts: the smart floor and the portable terminal unit. The smart floor is a floor of a building where each tile of the floor has the passive RFID tag which transmits a unique ID number. The portable terminal unit is an embedded system equipped with an RFID reader as an input device so that the BIGS can get the current location information of the user. Using the preinstalled map of the target floor, the blind person can navigate to the final destination. The prototype is implemented and successfully operated.
