Good news for blind people wanting to travel on the London Tube.
While at the moment they still have to rely on station staff to assist them on
to their train, a new smartphone app created by the Royal London Society for Blind People (RLSB’s)
Youth Forum and digital product studio ustwo could
help them in the future navigate the city independently.
The app, called Wayfindr, uses Bluetooth and beacon technology to trace the
user’s location in the subway and give him audible directions. A prototype has
been recently trialled at Pimlico station, where sixteen beacons have been
installed.
The system is pretty clever: it uses bone conduction headphones that
rest on the blind person’s cheeks, giving him turn-by-turn directions on where
to go and on the obstacles to avoid, each time a beacon’s signal is picked up
by the smartphone.
At the same time, the headphones do not prevent wearers from
hearing the sounds around them, allowing them to gather more information about
the surrounding environment.
Although the tests have been very promising, as Kevin, one the
first users said, there
is still a long road ahead to Wayfindr being rolled out to the masses, and more
testing needs to be done to ensure perfect coverage.
London’s underground is huge, and a very large number of beacons
should be deployed. What’s more the whole system will need constant maintenance
to make sure there are no blind spots. It is unlikely that will completely
replace human intervention and assistance anytime soon.
Still, especially for young people, it could be a real
improvement of their travel experience. According to RLSB, there are an
estimated 7,000 blind and
partially sighted children in the London region (of 25,000 overall in
Britain), half of whom have difficulty using London’s transport network
independently. This kind of technology could help them feel empowered and more
confident about their capabilities.
