Every year on January 4th, the world comes together to celebrate World Braille Day, a day to honour the legacy of Louis Braille and the revolutionary system he created that empowers millions of people who are blind or visually impaired to read and write.
Born in 1809, Louis Braille himself lost his sight at a young age. Determined to overcome the limitations placed on the blind in his time, he developed a system of raised dots that could be felt with the fingertips, allowing him to read and write independently. This ingenious invention, known as Braille, transformed the lives of countless individuals, opening doors to education, employment, and self-expression.
What is Braille?
Braille is a tactile writing system used by people who are blind or have low vision. It allows them to read and write using their fingertips, opening up the world of literacy and communication in a way that transcends visual limitations.
Here's a breakdown of what Braille is all about:
Structure:
- Cells: Braille characters are formed within units called cells. Each cell consists of six raised dots arranged in two rows of three.
- Dot Combinations: The 64 possible combinations of these dots represent letters, numbers, punctuation marks, and even whole words.
- Grades: Different levels of complexity exist, from Grade 1 (letter-for-letter correspondence) to Grade 2, which includes contractions and abbreviations.
How does Braille Work?
Braille works through a fascinating combination of raised dots and fingertips! Here's how it breaks down:
The Braille Cell:
The core of Braille is the Braille cell, a rectangular space containing six raised dots arranged in two columns of three.
Each dot within this cell can be raised or not, creating 64 possible combinations (including the empty cell).
These combinations represent letters, numbers, punctuation marks, and even entire words or phrases (depending on the Braille code being used).
Reading Braille:
Braille readers run their fingertips, usually the index fingers, across the dots from left to right, feeling the raised patterns.
Each combination of raised dots corresponds to a specific character. With practice, readers can quickly recognize these patterns and decipher the text.
Skilled readers can use both hands, reading at speeds comparable to sighted readers with printed text.
