  • Publication number: 20130316312
    Abstract: The present invention includes a flat face, a dots raising mechanism, a display cell, a first column, a second column, an interface, and a connection port. The first column includes a first dot, second dot, and a third dot while the second column includes a fourth dot, a fifth dot, and a sixth dot. The columns are on the display cell. The display cell is capable of displaying a single Braille character. To convey information from a text source, the display cell raises and lowers the dots, successively forming different characters. A first time interval, a second time interval, and a third time interval help differentiate the first column from the second column, a first character from a following character, and a first word from a following word. The time intervals simulate physical space between and with the cells found in printed Braille.
