London's Underground network can feel like a maze for even the most seasoned traveller, especially at rush hour when you're packed in with hordes of disgruntled commuters. The problem is only amplified for blind and partially sighted people, but a combination of Bluetooth beacons and smartphone app could make the experience less stressful. Wayfindr has been developed by Ustwo (yep, the folks behind the video game Monument Valley) and the Royal London Society for Blind People's (RLSB) Youth Forum to offer travellers audio-based directions and advice. A month-long trial at Pimlico station is now underway with 16 beacons tracking users' smartphones and activating descriptive notes. The information is basic, but could offer valuable guidance and, hopefully, confidence to blind and partially sighted people navigating the Underground independently.
