Localization and Guidance in RAMPE/INFOMOVILLE-an interactive system of assistance for Blind travelers

We present in this paper the RAMPE/INFOMOVILLE system-an interactive man-machine-interface for the assistance, information, orientation and security of persons having visual or/and auditive handicap in public transports. We desrcibe this system, its components and operation. The current version doesn´t include a localization solution to guide the visually impaired person and assist him/her to reach the public transport station. A solution is proposed to address the needs of this application in terms of guidance and localization. We do base on the Wifi positioning system currently very wide spread and easy to use in localizing assets and people but that presents, however, some disadvantages highlighted in the body of this paper. Some modifications were brought to remedy these drawbacks in order to have a proprietary and adequate solution for our application. This solution is tested, an experiment is done and the results shown.
