Said solutions are often based on screen readers and call upon participants who are visually impaired…” </li></ul></ul>
  25. 25. Web Accessibility London City University London, 21 st September 2010 <ul><li>“ A loss or limitation of function in muscle control or movement or a limitation in mobility.

  30. 30. Web Accessibility London City University London, 21 st September 2010 Q: Why is it hard to get end users with disabilities involved in testing?
  31. 31. Web Accessibility London City University London, 21 st September 2010 <ul><li>Recruitment is dependent on the research & researcher being “seen” and “heard” within the target community. </li></ul><ul><ul><li>Conventional recruitment e.g. posters, flyers etc. can be ineffective . </li></ul></ul><ul><ul><ul><li>Solution: Visit disability centre's and youth/adult clubs to meet the target group, present at organizations & local authorities and advertise on websites and within newsletters that specialize in the target group. </li></ul></ul></ul>
  32. 32. Web Accessibility London City University London, 21 st September 2010 <ul><li>Support individuals may be present & can often contribute to research. </li></ul><ul><ul><li>Positive participant encouragement can reduce support individual contributions. </li></ul></ul><ul><li>Only using audio recordings is inappropriate. A combination of audio and visual recordings should be used. </li></ul><ul><ul><li>Body language is often used instead of natural speech or AAC devices. This cannot be picked up audibly </li></ul></ul>
