Berufsförderungswerk (BFW) Würzburg, Germany

For people who are blind or partially sighted, navigating an unfamiliar building is a daunting experience. Thanks to a partnership between KONE and BlindSquare, the students with visual impairments at Germany’s BFW Würzburg can ride the elevators and navigate the building independently, safely and confidently.
