The Braille keyboard, in the center, consists of 8 keys, of which the first 6 are the 6 Braille<br />

points in Perkins alphabetical order, the 2 others are the backspace (7) and space keys (8).<br />

A set of 20 or 40 piezoelectric cells located above the Braille keyboard enables Braille<br />

characters to be displayed. Each cell contains 8 points: points 1 to 6 serve to form the 64<br />

characters of the Braille alphabet; when points 7 and 8 are simultaneously raised, they<br />

represent the cursor.<br />
