7. 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. Through this technical method, information such as the
subway destination and how many stops are left can be alerted.

8. The destination and train travel information
are transmitted to the subway through the rail
tracks, used as a conductor, sent from the
TCC (Train Control Computer) in between
stations. The Metro Dot is able to provide
station location information by catching a
series of electronic signals that are being sent
to the subway’s receiver antenna
