What is a Braille System? Video Lecture | Science for Super TET

behold Braille but where did it come
from
meet Louie Braille born in 1809 in
France Louie Braille wasn't born blind
instead he lost his sight when he was
three years old he continued his
education but it was a struggle to learn
by listening alone luckily his hard work
paid off and he earned a scholarship to
the Royal Institution for blind youth in
Paris when he was just 10 years old but
even at this school Louie's education
was difficult the school had 14 books
written with raised letters but it took
too long to trace each letter Louie knew
there had to be a better way inspired by
French captain charles barbers method of
night writing Louie built on barbers
principles designing a way for the blind
to read quickly using their sense of
touch as their fingers passed across a
page today this system is known as
Braille earlier codes built to be
interpreted through touch had a common
flaw they made the Rays symbols too
large to be interpreted quickly Louie
designed his system using a six dot cell
where the letters of the alphabet are
represented by a specific pattern of
dots in the cell each cell can be read
without moving the fingertips by the
time he had invented this system Louie
was only 15 years old after graduating
from the Institute he returned to teach
although the Braille system wasn't
taught during his time at the Institute
Louie's system gained popularity in
France in 1854 the French government
officially recognized Braille and since
that time the rest of the world has
taken steps to incorporate the Braille
system in their language
