The Metro Dot
The Metro Dot is a bracelet type transportation card in Braille for the visually impaired. It relays information like your subway station and how many more stations to go before your stop arrives. The bracelet transmits vibrations to let the user know when to get off the train. The interface uses EAP (Electro Active Polymer) to make a 3 dimensional pattern with electronic signals. The electronic signals are sent to the surface raising the constant magnet to make a Braille pattern on the silicon rubber surface.
