DISHA : An Indoor Navigation System for the Visually Challenged
نویسندگان
چکیده
In this paper we outline the design for an indoor navigation system for the visually impaired. Our long-term goal is for a portable, self-contained system that will allow visually impaired individuals to travel through familiar and unfamiliar environments without the assistance of guides. The system, as it exists now, consists of the following functional components: (1) assistance for determining the user’s position and orientation in the building, (2) a detailed map of the interior of the building, and (3) the user interface. By pressing keys on his/her mobile unit, directions concerning position, orientation and navigation can be obtained by the portable system that can prompt them acoustically over a text-to-speech engine.

Indoor navigation is a challenging task for visually impaired people. Although there are guidance systems available for such purposes, they have some drawbacks that hamper their direct application in real-life situations. These systems are either too complex, inaccurate, or require very special conditions (i.e., rare in everyday life) to operate. In this regard, Ultra-Wideband (UWB) technology ...
