Beacon-Based Indoor Wayfinding for the Blind, Visually Impaired and Disoriented
There are few options for navigational aids for the blind and visually impaired (BVI) in indoor spaces, as technologies such as GPS used outdoors do not work indoors.
This project proposes to deploy low cost Bluetooth-based beacons (small, low cost wireless devices) at various locations indoors and then have users equipped with smartphones navigate through interactions with these beacons. If successful, the proposed system can be used for navigation in large indoor spaces like airports, train stations, grocery stores, malls, university buildings, etc. with minimal assistance.
