1. A Braille tablet with sensors for tracking the progress of a user's hands, the Braille tablet comprising:
a display including inner and outer surfaces, an array of tactile pins formed within the display and being selectively raised above or lowered below the outer surface, the array of tactile pins selectively forming a series of either six or eight pin Braille characters, the Braille characters being arranged in a series of columns, a series of alleyways positioned between the adjacent columns;
a microprocessor for controlling the tactile pins, the microprocessor selectively generating individual and refreshable six or eight pin Braille characters that can be read by the user;
a series of capacitive sensors formed on the inner surface of the display, each capacitive sensor being positioned within an alleyway and associated with an individual Braille character;
whereby as user touches the outer surface of the display at a location adjacent a Braille character the associated capacitive sensor signals the microprocessor such that the progress of the user's hands can be tracked and the Braille characters can be refreshed accordingly.
