Night writing is a method of writing that uses dots and dashes to represent letters and numbers. The spelling of this term can be explained using the International Phonetic Alphabet (IPA). The first syllable, "night," is pronounced [naɪt], with the diphthong "ai" and the voiceless alveolar stop "t." The second syllable, "writing," is pronounced [ˈraɪtɪŋ], with the voiced alveolar approximant "r," the diphthong "ai," the voiceless alveolar fricative "t," and the velar nasal "ŋ." Together, the word is pronounced [naɪt ˈraɪtɪŋ].
Night writing refers to a tactile reading and writing system that was developed by Charles Barbier in the early 19th century. Also known as sonography, it was intended to help soldiers to communicate silently during nighttime operations when traditional writing methods were impractical or dangerous. Night writing consists of a series of raised dots, similar to Braille, embossed onto paper or other surfaces.
The system works by using a 12-dot cell, with each dot representing a certain combination of letters, sounds, or words. The dots are arranged in two columns of six dots each, allowing for a total of 63 different combinations. By using these combinations, words and letters in different languages can be spelled out or represented. To read night writing, one would pass their fingers over the raised dots, feeling the different configurations and interpreting them accordingly.
Although night writing was originally created for military purposes, it eventually sparked the interest of Louis Braille, a blind Frenchman. Braille modified the system, reducing the cell to only six dots, thus creating the well-known Braille system that is widely used today by visually impaired individuals. While night writing itself is not as prevalent today, it played a significant role in the development of tactile reading and writing systems, laying the foundation for future applications and advancements in the field.
The etymology of the term "night writing" can be traced back to its inventor, Charles Barbier. In the 19th century, Barbier created a writing system called "Ecriture Nocturne" in French, which translates to "night writing" in English. Barbier initially developed this system for military use, specifically for soldiers to communicate silently and without light during nighttime operations. Eventually, this writing system evolved into what we now know as braille, after Louis Braille modified and refined it to be more efficient and easier to read. So, the term "night writing" refers to the original concept and purpose behind this writing system's creation.
