 How do blind people use a computer?

Despite the fact that blind people can type on ordinary keyboards, they must rely on specific software and hardware to view the information shown on a computer screen.

Screen Readers

A screen reader is a piece of software that interprets what's on the screen and relays it to the user via a text-to-speech engine or a refreshable braille monitor. It allows blind and visually disabled individuals to read notes, search the internet, submit e-mails, and work through an application's menus and dialogue boxes.

Since blind people cannot use a mouse, they must rely solely on keyboard commands to complete tasks that sighted people can complete with a mouse. These keyboard commands include those integrated into the computer's operating system or a specific software program, such as CTRL+C for copying the selected text.

A refreshable braille monitor is a computer-connected electronic interface with a USB or Bluetooth link. Its function is to display braille output from a screen reader, which is a blind writing device that uses raised dots to represent letters, numbers, punctuation signs, and other symbols.

A braille show is made up of a row of cells, each of which has eight holes and eight matching pins situated within the cells. The pins are lifted to form braille characters that refer to the text under the cursor. When the user has done reading a line of text, they will switch to the next line by pressing a button. This causes the braille cells to refresh and to display the next line of text.
