The Metro Dot bracelet provides location and travel information to visually impaired subway users through vibrations in Braille. It transmits electronic signals that raise magnets on the bracelet's surface to form Braille characters indicating the current station and number of remaining stops. Destination and travel information is sent from the train control computer to the bracelet via the subway tracks. The bracelet allows independent travel by notifying users through Braille vibrations of when to disembark from the train.
