The Telegraph reports that blind residents of Turin have been equipped with GPS trackers so that they can be directed around the northern Italian city by satellite.
" When wearing the device, a blind user can be tracked by call-centre workers on a map of the city. If he needs help, he can press a special button on a mobile phone to ring in and be guided towards his destination.
Another button can alert staff in case of an attack, or another emergency. The trial scheme, named B>Easy Walk, started last week.
The service runs 24 hours a day and can work across Italy and even France."
