Generally, blind people do not use a special keyboard. They can write and enter information through the common keyboard used by people with vision. But although blind people do not use a special keyboard, they require special software.
This software is called a screen reader. A screen reader takes the information displayed on the screen and provides it in a format that blind people can understand. Without the screen reader, it would be very difficult for the blind to access the computer.
A screen reader provides information in two main formats. The first format is a voice output that users can listen through the computer speaker. This voice output allows users to hear the highlighted text and the keys they press. The second format is provided through a Braille display. It is a hardware that displays Braille text translations on the screen. Some Braille displays even have Braille keyboards that blind people can use as an alternative.
With these technologies, blind people do not really need a special keyboard because they can easily write information and ensure accuracy. I would also like to mention the fact that people who can write very fast, even though they can see, know the keyboard so well that they do not have to look at it when typing. This shows that you do not need to see the keyboard or use a specialized one so that you can enter information into the computer.
