Decapoint

Decapoint, or raphigraphy, was a tactile form of the Latin script invented by Louis Braille as a system that could be used by both the blind and sighted. It was published in 1839. Letters retained their linear form, and so were legible without training to the sighted, but the lines were composed of embossed dots like those used in braille. Each letter contained ten dots in the height and different dots in the width to produce the graphic form of print.
