A Perkins Brailler is a machine that helps people with visual impairments write and read in braille.
Braille is a system of raised dots on a page that people who can't see can touch with their fingers to read letters, words, and numbers.
The Perkins Brailler looks a bit like a typewriter, but instead of typing letters, it punches braille dots onto a piece of paper using small metal rods called pins.
When someone wants to write something in braille, they press down on the keys of the Perkins Brailler to punch the corresponding dots onto the paper. The machine has six keys, and each key is associated with a different dot. With these six keys, someone can make any combination of braille letters, numbers, and symbols.
The paper used with a Perkins Brailler is thicker than regular paper, so the pins can leave an indentation in the paper that can be felt with the fingers. This makes it possible for someone who is blind or visually impaired to read what's been written in braille.
The Perkins Brailler is an important tool for people with visual impairments, as it allows them to communicate, learn, and participate in the world around them.
