Researchers from Carnegie Mellon University (CMU) and Pittsburgh International Airport have launched a new smart suitcase that assists blind and visually-impaired travellers to navigate airport terminals safely and independently.
In collaboration with CMU, IBM has also developed a new app that uses Bluetooth technology to create a beacon system to help users navigate their way through the airport terminal. The NavCapp navigation app provides audio instructions to users when they are heading for a collision with a pedestrian and assists them to reach a departure gate, restaurant, or bathroom.
As part of a pair of user studies conducted at Pittsburgh International Airport, both Bbeep and NavCog were proved to be effective.
