The 'braille' system is a typhograph ("writing for the blind") that uses monospaced characters to read by touch, composed of up to 6 embossed dots located in the form of a seine, which gives a maximum of 64 combinations. There is an extended 8-point system (which includes the 6-point system) and allows you to use up to 256 characters, but it is less used. The name comes from its creator, the Frenchman Louis Braille, who was inspired by a military method to carry written messages to the front lines at night, without thinging down the position when reading them since it was not necessary to turn on a light.
