IBM, Carnegie Mellon are building a navigation app for the blind

IBM Research and Carnegie Mellon University are working on a smartphone app that would help blind and visually impaired people navigate their surroundings, by communicating information about the users surroundings to them via audio cues or vibrations. The app, called NavCog, will initially be specific to the Carnegie Mellon campus, as it will rely on Bluetooth beacons placed around walkways and in buildings.
