Travellers with visual impairments are testing a new app in London that could help them and other such passengers to navigate public transport independently.
The Wayfindr system, being trialled at London's Pimlico metro station, uses 16 Bluetooth beacons to transmit signals to mobile phones. The app then uses these to give spoken directions to users, helping them to find their way in the station.
A spokesperson for London Underground said: 'We are delighted to be able to support this trial, which has developed directly from the desire of visually impaired people to get around on their own.
'While we have staff at all Tube stations to help people whenever they need it, we're always keen to see how technology and innovation can help open up and make our networks more accessible.'
Wayfindr's ultimate aim is to standardise all audio signage across London's transport network, making it easier for blind and partially sighted people to use its services. The app was developed Royal London Society for Blind People's Youth Forum and ustwo, a company that develops digital products.
