libbrailleReading by touch

An independent publication about braille and tactile reading. A C library called libbraille was once one of the pieces of software that let Linux drive a braille display. This publication is not that software and has nothing to do with it.

Reading by touch

Six positions. Sixty-four patterns. Everything after that is engineering.

A braille dot stands about half a millimetre off the page and sits 2.34 mm from its neighbour. Those numbers, and the width of a fingertip, decide almost everything else: how much a page holds, why contractions exist, and how a machine has to be built to raise a dot and then take it away again.

Six positions

Dots 1–2–3 down the left column, 4–5–6 down the right.
Positions, not a character. Nothing here claims to spell anything.

Symbol recognition gets the attention. The harder job is knowing where you are on the page.
