Answer 2

Answer:

Eventually Barbier introduced his concept to the blind at the suggestion of members of the French Royal Academy of Sciences. In 1821, students at the Royal Institution for Blind Youth in Paris assembled for a demonstration of Barbier's system. It was favorably received, because the older system of embossed Latin letters with its curves and straight lines was much harder for blind people to understand than the simple patterns of dots, and they could not use the system to write or take notes. Barbier also provided a system by which the students could write his symbols, using a special writing board and a pointed tool to make the dots.
