What is brallete?

Braille is a system of raised dots that can be read with the fingertips by people who are blind or visually impaired. It was developed by Louis Braille in the 1820s, based on a tactile military code used by the French army. The system is based on a grid of six dots arranged in two columns of three, which can represent letters, numbers, punctuation, and many other symbols. Braille can be produced using a variety of tools, including slate and stylus, braille typewriters, and electronic braille displays. It is used in many different contexts, including education, literature, and communication, and has been an important tool for blind people around the world for over 200 years.
