Screenreader

Maria Barreiras Nº19

What is a screen reader?

It is a form of Assistive Technology, mainly used by people with vision impairments. It converts text, buttons, images and other screen elements into speech or braille. This software makes it easier for people with visual impairment to use the computer and browse the Internet on their own.

What is Assistive Technology?

It is any item, piece of equipment, software program, or product system that is used to increase, maintain, or improve the functional capabilities of people with disabilities.

How does a screen reader work?

All screen readers use a wide variety of keyboard commands to carry out different tasks:

  • reading part or whole of a document;
  • navigating web pages;
  • opening and closing files;
  • editing;
  • listening to music.

Computer screen readers

On a computer, users will usually navigate using their keyboard. Either stepping from object to object or by jumping between different types of components, like headings, forms, links or landmarks.

Mobile screen readers

Instead of using a keyboard, you can navigate by moving your finger on the screen in two ways:

  • Touch navigation: dragging your finger across the screen, and getting what´s under your finger read to you.
  • Swipe navigation: swiping left and right to move to the next or previous item.

What are the most popular screen readers?

  • JAWS
  • NVDA

Many mobile phones have built-in screen reader-like capabilities, which makes them indispensable to those with vision impairments. Apple offers VoiceOver and Android has TalkBack.
