A recent press release from the University of Florida describes a navigation system for the blind that student Steve Moore has worked on for several years. The system integrates GPS, a GIS database, a compass, and other sensors to provide the wearer with exact information about where they are, what direction they're facing, what obstacles are present in the room or surroundings, directions to get from where they are to their destination, even where the nearest restroom or waterfountain is. The applications of such a system for autonomous robots should be numerous. More information can be found at the project's website.
