Abstract: Disclosed is a tablet with an improved Braille display. The Braille display employs a pin array that allows for the selective use of either six or eight pin cells. This is accomplished by turning off or on a pin pair adjacent to each cell. The spacing of the pins also allows capacitive sensors to be located adjacent to each Braille cell. These sensors are used to determine the location of the user's finger upon the display. The pin spacing further allows geometric shapes to be generated in additional to text.
