Carnegie Mellon University researchers say a smart suitcase that warns blind users of impending collisions and a wayfinding smartphone app can help people with visual disabilities safely and independently navigate airport terminals. Called BBeep, the suitcase sounds alarms when users are headed for a collision with a pedestrian, and the navigation app, called NavCog, provides turn-by-turn audio instructions to users on how to reach a departure gate -- or a restroom or restaurant. Together, the technologies could reduce the need for airport personnel to serve as guides for the visually impaired.
