Smartphone Navigation for the Visually Impaired


Within the past year, researchers have been demonstrating some promising new ways to help the visually impaired navigate based on technologies originally developed for the greater geospatial community.  One of these efforts is hand-held sonar.  Another is leveraging the diverse and powerful capabilities inherently available in modern smartphones. 

Within this last area of research, the University of Minnesota Center for Transporation Studies has been hard at work on a system that seamlessly integrates multiple smartphone features such as GPS, Wi-Fi, and digital compass to provide visually impaired pedestrians with enhanced safety at street intersections.  To learn more about this development, use the links below:
