Designers Seung-Hyun Yoon, Seol-Hee Son & Ji-Youn Kim have designed a braille navigation aid that communicates to its user both through speech and braille.
The Brainovi uses a combination of verbal instructions and touch display, to help a blind person travel alone.
To start the user simply speaks their destination into the device ,then up pops a 3D map to help them find their way by braille.
The 3D map is used in conjunction with a Bluetooth earpiece that guides the user via verbal directions.
The Brainovi device has been designed to provide users sense of freedom while traveling alone, without depending upon a companion.
