Braille reworked Barbier's system by simplifying its form and maximizing its efficiency. He made uniform columns for each letter, and reduced the maximum of twelve raised dots to six. [[1829 braille|His first version]] used both dots and dashes. He published this version in 1829, but by the second edition in 1837 discarded the dashes because they were too difficult to read. Crucially, Braille's smaller cells were capable of being recognized as letters with a single touch of a finger.<ref name=Farrell98/>
Braille worked tirelessly on his ideas, and his system was largely completed by 1824, when he was fifteen years old.<ref name=Farrell98/><ref name=Olmstrom/> He innovated on Barbier's system by simplifying its form and maximizing its efficiency.

Braille created his own raised-dot system using Barbier's [[slate and stylus]] tools. Barbier had donated many sets of these tools to the school. By soldering metal strips across the slate, Braille created a secure area for the stylus which would keep the lines straight and readable.<ref name=Farrell98/>
