Misbar’s Analysis
The Braille system, created by French inventor Louis Braille, revolutionized written communication for the blind and visually impaired. It was inspired by a military "night writing" system used by soldiers in the early 19th century, allowing them to read and write in the dark without the need for light. Despite initial resistance, the Braille system endured and remains widely used today. Often referred to as Braille technology, it continues to be an essential tool, enabling millions to access written content worldwide.
How Many Characters Are in the Braille System?
The number of characters in the Braille system can vary depending on the language. Braille is adapted to match the specific alphabet of each language. For example, the Arabic Braille system consists of 28 characters, corresponding to the 28 letters in the Arabic alphabet. However, the complete Braille system for the visually impaired contains 63 distinct symbols, including letters, numbers, and punctuation marks, allowing for comprehensive written communication.
What Is the Braille System?
The Braille system is a tactile writing method that enables visually impaired individuals to read and write. It uses a grid of six raised dots arranged in different patterns to represent letters, numbers, and other symbols. This innovative system allows people who cannot see conventional written words to read by touch, empowering them to access information and engage with written content. According to the United Nations, Braille has been a key tool for accessibility and education for the blind and visually impaired community.
When Was Braille Invented?
Louis Braille, the inventor of the Braille system, lived from 1809 to 1852, passing away at 43. His groundbreaking invention, created to help blind people read, emerged in the 19th century. In 1829, Braille published his thesis on this innovative tactile writing method, which underwent several refinements over time. These developments eventually led to the creation of modern Braille tools that continue to assist visually impaired individuals in reading today.
What Did Louis Braille Invent?
Louis Braille, who lost his sight at a young age, went on to create the revolutionary Braille system. As explained in the historical encyclopedia History, Braille developed his method in the 1820s to help the blind read and write. In 1829, he published a thesis outlining the system, followed by the release of a three-volume book printed using his tactile method. Today, his invention is widely recognized as the Braille system or Braille technology, an essential tool for visually impaired individuals around the world.
The Story of Braille
The story of Braille is one of determination and innovation. Louis Braille, born with perfect vision, tragically lost his sight in childhood due to a traumatic accident. Driven by the desire to help blind people read and write, he devoted himself to creating a system that would make literacy accessible to those without sight. In the 19th century, Braille succeeded in developing this groundbreaking method, which continues to empower millions today. Here are some key milestones in his inspiring life:
- Losing Vision in One Eye: Louis Braille was born in 1809 in France. At just 3 years old, while playing in his father’s workshop, he accidentally injured his eye with a sharp object, causing permanent vision loss in that eye.
- Complete Blindness: Soon after the injury, Louis contracted a severe infection in his remaining eye, which led to total blindness by the time he was 5 years old.
- Joining the Royal Institution for Blind Youth: At age 10, Louis Braille enrolled at the Royal Institution for Blind Youth in Paris. Despite his challenges, he quickly stood out as one of the brightest and most dedicated students at the institution, setting the stage for his later groundbreaking work.
- Discovering Night Writing: In 1821, Louis Braille was introduced to Night Writing, developed by French military officer Captain Charles Barbier. This tactile communication system was originally designed for soldiers to read messages in the dark, without the need for light.
- Developing a Writing System for the Blind: In 1824, Braille began adapting and simplifying Night Writing. He reduced the number of dots and simplified the design to create a more efficient and accessible method for blind people to read and write.
- Publishing the Braille Alphabet: After years of development, Louis Braille published his groundbreaking system in a thesis in 1829. He continued to refine and promote it, publishing several works using Braille in the years that followed, making it a revolutionary tool for the blind community.
- Facing Objections: Despite the groundbreaking nature of his invention, the Braille system initially faced resistance and was not widely accepted. It wasn’t until two years after Louis Braille's death that his system was officially approved for use at the Royal Institution for Blind Youth.
- Return to Coupvray: In 1852, due to a worsening respiratory illness, Louis Braille returned to his hometown of Coupvray. He passed away later that year at the Royal Institution infirmary, leaving behind a legacy that would go on to transform the lives of millions.
Key Tools Invented for the Braille System’s Use
Louis Braille’s invention has not only been meticulously studied by experts but also inspired the creation of essential tools that enhance reading for the blind. One of the earliest innovations was the Perkins Brailler, developed by American inventor David Abraham in 1951. Remarkably, more than 70 years after its creation, the Perkins Brailler continues to be an invaluable tool for Braille literacy.
In 1971, the first printers capable of producing computer-generated text on Braille paper were introduced, marking a significant step forward in Braille technology. Four years later, in 1975, Dortmund University in Germany developed the first electronic Braille line device. Then, in 2004, the company HumanWare launched what was described as the first Braille line device to operate via Bluetooth technology, further revolutionizing how Braille is accessed and read.
How Is Arabic Braille Written?
Writing in Arabic Braille requires understanding the basic units of the system for the visually impaired, as well as adherence to several guidelines. Here are some important tips for writing in Arabic Braille:
- Understanding the Braille Cell: Braille is based on units called Braille cells, which consist of six dots arranged in two columns, each containing three dots.
- Starting from the Top Left: Writing in Braille should begin from the left column, not the right. Also, writing starts from the bottom of the cell and moves upward to the top dots.
- Recognizing Each Letter: Each Arabic letter has its own unique symbol. It's essential to learn the symbol for each letter. For example, the letter "Alif" is represented by a single raised dot (dot 1).
- Learning Number Symbols: The number symbols in Braille differ from the letter symbols. The number 1 is represented by two dots: dot 1 followed by dot 2, and so on until all numbers are learned.
- Starting New Paragraphs Correctly: To help blind readers find the beginning of paragraphs in Braille books, new paragraphs should begin at the third space of the line.
- Word Segmentation: A single word in Braille may take up more space than usual due to the segmentation of the word into individual letters using the six-dot system. The writer can split a word into two lines, provided that the word or syllable is consistent across both lines.
- Punctuation Marks: When writing punctuation marks in Braille, they should be placed directly after the word, without any space. A space should be left after the punctuation mark.
- Including Foreign Letters: Arabic Braille allows the use of foreign letters. However, the writer must use dot 4 before any letter pronounced differently from the Arabic pronunciation, such as the first letter in "Victoria."
Modern Devices Related to Braille Technology
Although Braille was invented in the 19th century, it remains at the heart of many modern devices that assist the visually impaired. Today, several innovative tools are designed to enhance accessibility, including the Braille Sense U2, which allows users to read eBooks and process text; the compact Smart Beetle device; the e-Bot Pro; and the Braille Blaze ET. These devices continue to improve the reading and writing experience for Braille users.
