Inclusive New Media Design

including people with intellectual disabilities in the WWW

Previous research

People who have looked into making websites work for people with intellectual disabilities have said:

  • It’s difficult for this group to work with text
  • Web users should be able to listen to words, as well as read them
  • Web pages should include a small amount of words
  • It should be clear and obvious where buttons will take you
  • Pictures and text should be big
  • Words should be clear and simple.

Very little research has been carried out on web accessibility and intellectual disability. Peter Williams and David Nicholas summarise some of this work in ‘Testing the usability of information technology applications with learners with special educational needs’ in The Journal of Research in Special Educational Needs, volume 6, number 1, 2006.

Processing text

Harrysson and others carried out a studied with a small group of intellectually disabled people aged 15-44. They found that these users were adept at navigation, but had difficulty with text input, and concluded that ‚Äòthe processing of text can impede accessibility to the Internet for people with cognitive disabilities’.

(‚ÄòHow people with developmental disabilities navigate the Internet’, British Journal of Special Education , 31(3))

Expert panel results

Brown and others examined the usability of an interactive multimedia learning environment for people with intellectual disabilities, consulting an expert panel. They produced the following accessibility guidelines (and others) as a result:

  • Accessibility: provide a speech alternative of all buttons and text
  • Navigation: provide a menu that allows the user to jump to anywhere at any time & an exit button
  • Pedagogic structure: provide regular rewards, reinforcement and tests
  • Aesthetics: use a maximum of three sentences per page

On dyslexia

The Disability Rights Commission commissioned research into the accessibility of websites, and found the following key problems affecting people with the specific learning difficulty of dyslexia:

  • Unclear and confusing layout of pages
  • Confusing and disorienting navigation mechanisms
  • Inappropriate use of colours and poor contrast between content and background
  • Graphics and text too small
  • Complicated language or terminology
