Braille in the context of "History of writing"

Language is a structured system of communication that consists of grammar and vocabulary. It is the primary means by which humans convey meaning, both in spoken and signed forms, and may also be conveyed through writing. Human language is characterized by its cultural and historical diversity, with significant variations observed between cultures and across time. Human languages possess the properties of productivity and displacement, which enable the creation of an infinite number of sentences, and the ability to refer to objects, events, and ideas that are not immediately present in the discourse. The use of human language relies on social convention and is acquired through learning.

Estimates of the number of human languages in the world vary between 5,000 and 7,000. Precise estimates depend on an arbitrary distinction (dichotomy) established between languages and dialects. Natural languages are spoken, signed, or both; however, any language can be encoded into secondary media using auditory, visual, or tactile stimuli – for example, writing, whistling, signing, or braille. In other words, human language is modality-independent, but written or signed language is the way to inscribe or encode the natural human speech or gestures.

The history of books begins with the invention of writing, as well as other inventions such as paper and printing; this history continues all the way to the modern-day business of book printing. The earliest knowledge society has on the history of books actually predates what we came to call "books" in today's society, and instead begins with what are called either tablets, scrolls, or sheets of papyrus. The current format of modern novels, with separate sheets fastened together to form a pamphlet rather than a scroll, is called a codex. After this invention, hand-bound, expensive, and elaborate manuscripts began to appear in codex form. This gave way to press-printed volumes and eventually led to the mass-market printed volumes that are prevalent today. Contemporary books may even start to have less of a physical presence with the invention of the e-book. The book has also become more accessible to the disabled with the invention of Braille as well as audiobooks.

The earliest forms of writing began with etching into stone slabs, evolving over time to include palm leaves and papyrus in ancient times. Parchment and paper later emerged as important substitutes for bookmaking, as they increased durability and accessibility. Ancient books were made from a variety of materials depending on the region's available resources and social practices. For instance, in the Neolithic Middle East, the cuneiform tablet was part of a larger clay-based toolkit used for bureaucracy and control. In contrast, while animal skin was never used to write books in eastern and southern Asia, it became a mainstay for prestige manuscripts in the Middle East, Europe, and the Americas. Similarly, papyrus and even paper were used in different regions at various times, reflecting local resource availability and cultural needs. Across regions like China, the Middle East, Europe, and South Asia, diverse methods of book production evolved. The Middle Ages saw the rise of illuminated manuscripts, intricately blending text and imagery, particularly during the Mughal era in South Asia under the patronage of rulers like Akbar and Shah Jahan. Prior to the invention of the printing press, made famous by the Gutenberg Bible, each text was a unique, handcrafted, valuable article, personalized through the design features incorporated by the scribe, owner, bookbinder, and illustrator.

A tactile alphabet is a system for writing material that the blind can read by touch. While currently the Braille system is the most popular and some materials have been prepared in Moon type, historically, many other tactile alphabets have existed:

A refreshable braille display or braille terminal is an electro-mechanical device for displaying braille characters, usually by means of round-tipped pins raised through holes in a flat surface. Visually impaired computer users who cannot use a standard computer monitor can use it to read text output. Deafblind computer users may also use refreshable braille displays.

Speech synthesizers are also commonly used for the same task, and a blind user may switch between the two systems or use both at the same time depending on circumstances.

The Perkins Brailler is a "braille typewriter" with a key corresponding to each of the six dots of the braille code, a space key, a backspace key, and a line space key. Like a manual typewriter, it has two side knobs to advance paper through the machine and a carriage return lever above the keys. The rollers that hold and advance the paper have grooves designed to avoid crushing the raised dots the brailler creates.

Although braille notation was designed for people who are blind or visually impaired to read, prior to the introduction of the Perkins Brailler, writing braille was a cumbersome process. Braille writers created braille characters with a stylus and slate (as developed by Louis Braille) or by using one of the complex, expensive, and fragile braille writing machines available at the time.

A braille embosser is an impact printer that renders text as tactile braille cells. Using braille translation software, a document or digital text can be embossed with relative ease. Braille embossers can emboss single-sided or double-sided (called interpoint) and can produce 6- or 8-dot braille.

Blind users tend to call other printers "ink printers," to distinguish them from their braille counterparts. This is often the case regardless of the type of printer being discussed (e.g., thermal printers being called "ink printers" even though they use no ink).

Louis Braille (/breɪl/ brayl; French: [lwi bʁɑj]; 4 January 1809 – 6 January 1852) was a French educator and the inventor of a reading and writing system named after him, braille, intended for use by visually impaired people. His system is used worldwide and remains virtually unchanged to this day.

Braille was blinded in one eye at the age of three. This occurred as a result from an accident with a stitching awl in his father's harness-making shop. Consequently, an infection set in and spread to both eyes, resulting in total blindness. At that time, there were not many resources in place for the blind, but he nevertheless excelled in his education and received a scholarship to France's Royal Institute for Blind Youth. While still a student there, he began developing a system of tactile code that could allow blind people to read and write quickly and efficiently. Inspired by a system invented by Charles Barbier, Braille's new method was more compact and lent itself to a range of uses, including music. He presented his work to his peers for the first time in 1824, when he was fifteen years old.

Night writing is the name given to a form of tactile writing invented by Charles Barbier de la Serre (1767–1841). It is one of a dozen forms of alternative writing presented in a book published in 1815: Essai sur divers procédés d'expéditive française, contenant douze écritures différentes, avec une planche pour chaque procédé (Essay on various processes of French expedition, containing twelve different writings, with a plate for each process). The term (in French: écriture nocturne) does not appear in the book, but was later applied to the method shown on Plate VII of that book. This method of writing with raised dots that could be read by touch was adopted at the Institution Royale des Jeunes Aveugles (Royal Institution for Blind Youth) in Paris in 1821.

A student at the school, Louis Braille, used the tools and Barbier's idea of communicating with raised dots in a form of code, and developed a more compact and flexible system for communications, Braille.
