A new navigational Braille Map called The Brainovi  used verbal instructions and touch to assist the blind in traveling alone. They speak the destination into the device and a 3D Braille map shows up so that they can feel their way to the destination. Designers: Seung-Hyun Yoon, Seol-Hee Son & Ji-Youn Kim
