Historical information
Designed to create an impression on paper, the slate allows users to create Braille by guiding the stylus into the correct alignment to produce Braille, through the applied use of pressure that creates a depression on one size of the paper and a raised dot on the alternative side. In this example, the frame has two side hinges which allow it to sit over the paper edge, and four lines of Braille could be written.
