Our Sense Of Sight

It´s very important to take care of our senses. Today we read and talk about blind people and the way they live.

Braille is a tactile writing system used by people who areblind and low vision. It is traditionally written with embossed paper. Braille-users can read computer screens and other electronic supports thanks to refreshable braille displays. They can write braille with the original slate and stylus or type it on a braille writer, such as a portable braille note-taker, or on a computer that prints with a braille embosser.
Braille is named after its creator, Frenchman Louis Braille, who lost his eyesight due to a childhood accident. In 1824, at the age of 15, Braille developed his code for the French alphabet as an improvement onnight writing. He published his system, which subsequently includedmusical notation, in 1829.[1][2] The second revision, published in 1837, was the first binary form of writing developed in the modern era.
Braille characters are small rectangular blocks called cells that contain tiny palpable bumps called raised dots. The number and arrangement of these dots distinguish one character from another. Since the various braille alphabets originated as transcription codes of printed writing systems, the mappings (sets of character designations) vary from language to language. Furthermore, in English Braille there are three levels of encoding: Grade 1 - a letter-by-letter transcription used for basic literacy; Grade 2 - an addition of abbreviations and contractions; and Grade 3 - various non-standardized personal shorthands.
Here´s a video that I´d like you to watch carefully and try to be more sensitive with people with different capacities than ours.

Through Their Eyes
