ABSTRACT
We outline the design for a navigation system for the visually impaired and describe the progress we have made toward such a system. 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) a means of determining the traveler's position and orientation in space, (2) a Geographic Information System comprising a detailed database of the surrounding environment and functions for automatic route planning and for selecting the database information desired by the user, and (3) the user interface.
