braille printers and keyboards

  A braille keyboard.

 

It is a keyboard with braille input. Braille Technology is capable of revolutionizing the lives of thousands of people because it allows them to engage in the virtual world that cannot be perceived through their eyes. Braille Technology allows blind or visually impaired people to do common tasks such as writing, browsing the internet, typing in Braille and printing in text, engaging in chat, downloading files, music, using electronic mail, burning music, and reading documents. Braille keyboards were in use only with Braille typewriters. Braille reading computer users prefer the standard keyboard as a text composing input device. Braille computer keyboards are extremely rare.
