Braille

Braille is a way for blind people to read and write things with their fingertips instead of their eyes. It's like a secret code that uses bumps on paper or other materials, called braille cells.

Each braille cell has six bumps that can be arranged in different ways to create letters or symbols. The bumps can be felt by running your fingertips over them.

For example, the letter "A" in braille is made up of one bump in the top left corner of the braille cell.

Braille is used for things like books, signs, and even on some computer screens. Blind people can read braille by using their fingertips to feel the bumps on the paper or other materials. Some people also use special machines called braille writers to write in braille.

Overall, braille is an important way for blind people to communicate and access information just like how sighted people use their eyes to see things.
