Electronic Navigation System for Visually Impaired

PERCEPT is an electronic navigation system that provides verbal directions, electronic signs and a virtual information booth for helping the visually impaired around subway stations. The innovative system can be used with a smartphone through a special application with pre-set instructions and near field communication software (NFC) which allows the phone to communicate with electronic tags installed throughout the station. The system hopes to enhance the perception of the blind and visually impaired in unfamiliar indoor environments. A prototype will be tested with 10 visually impaired people in a downtown Boston subway station and will be open to the public in 2016.
