"A ground-breaking trial is underway at Pimlico Underground station to assist blind and partially sighted people to navigate independently, using Bluetooth beacons and a smartphone app," according to
Medical News Today. "The Wayfindr system has been developed by ustwo, a studio which builds digital products and services, in response to the RLSB Youth Forum's desire to be able to navigate London Underground (LU) without assistance. The beacons transmit a signal that can be picked up by smartphones and mobile devices. Wayfindr uses these signals with ustwo's indoor positioning technology to locate itself and give audible directions to the user. The app is paired with commonly available 'bone conduction' earphones that do not prevent wearers from hearing the sounds around them."
