Hi-tech Headset to Guide Blind People

A headset that guides visually impaired people around cities has been designed by Microsoft and the Guide Dogs charity.

The headset provides directions and live transport information, and ‘paints a picture of the world through sound’ – it claims to let you hear your surroundings as a “3D soundscape”. Paired with a smartphone, it uses location information from Microsoft’s Bing maps, which can be supplemented by tiny Bluetooth-enabled beacons stuck to lamp-posts around the city. the headset contains a GPS tracker, compass and gyroscope, and can be programmed to talk to you through your route, like a pedestrian sat-nav.
