It's not very easy for the visually impaired to get around using the subway, but the 'Metro Dot' 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'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'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' announcements. With a device like this, people will be well-informed about their travels without facing any unnecessary trouble in the subway.
