Display for the Blind

This display comprises a single-character Braille cell display by means of which a full page of Braille character is presented a character at a time by way of the cell, and a steering tablet is used for designating the character at which the reader wishes to access the page.

The display comprises a unitary housing 10, of more or less conventional form, having a control panel 12, a single character Braille cell display 14 and a steering tablet 16.

Any character on the page can be selected by the operator for starting the data displayed on the single-character cell display 14.
