WASHINGTON (Reuters) - An app designed to help visually impaired or blind pedestrians use public transit will debut at a Washington subway station on Tuesday.
Waymap aims to expand travel options for blind and visually impaired people with step-by-step audio directions that it says are accurate up to 3 feet (0.9 meter) throughout a trip.
