Red-green color blindness doesn’t stop people from navigating through traffic. That’s because the rules for pedestrians are simple.
For people with visual impairments, however, the big city remains a dangerous place.
A smartphone app, devised at the University of Minnesota, tested how to help people who are partially sighted cross the road safely. It’s been dubbed as Google Maps for the visually impaired.
Upon reaching an intersection the app connects with a traffic light. The pedestrian taps the screen to receive audio-visual information about their location and the number of traffic lanes.
If the light changes to green, they are told how long they have to cross. The goal? To make cities accessible for all.
Walk this way!
