Assistive technology
The shift in modern Western culture away from oral storytelling to the written and printed word has created a barrier for the visually impaired. Writing and self-editing prose writing is often impossible without the use of assistive technology. Software developed for the visually impaired, called screen readers, enable users to hear a voice reading the user's choice of digital printed material, such as e-books or Websites. Braille keyboards enable users to type and edit using a computer. Assistive technology is also available to help users with a learning disability, such as dyslexia, that impairs literacy, to read and write more easily using computers.
