"It&amp;#039;s not very easy for the visually impaired to get around using the subway, but the &amp;#039;Metro Dot&amp;#039; design is a high-tech device that will help people use the transportation system more easily.  These folks solely rely on announcements, but subways aren&amp;#039;t always a quiet place and that can be a problem. The Metro Dot is a bracelet-like watch that comes equipped with a Braille system that relays information about subway stops and other important information. It vibrates to let users know when they&amp;#039;re approaching their destinations.  This design by Hoyeoul Lee, Jinwoo Kim and Sangyong Choi allows the visually impaired to relax without having to rely on train conductors&amp;#039; announcements. With a device like this, people will be well-informed about their travels without facing any unnecessary trouble in the subway."^^<http://www.w3.org/2001/XMLSchema#string>
