GPS Device for the Blind

Allan Sejer Madsen and Lukasz Natkaniec from Poland, have developed a GPS device for the blind called "DROP" GPS system.  The device is in a shape of a disk and senses it location using GPS Technology.  The grid is made of 3D moveable dots so the user can feel the maps, very similar to braille. It also has a zoom, search, and voice command feature as well.

I think this device is pretty cool and in the future can help the blind get around without a see ans eye dog or a walking stick. What do you think?
