Understanding Web Accessibility and Its Drivers

  1. 1. Understanding Web Accessibility and Its Drivers Yeliz Yesilada, Giorgio Brajnik, Markel Vigo and Simon Harper
  2. 2. How do YOU perceive web accessibility?1. What is the main motivation for embracing accessibility?2. Is web accessibility specific to disabled people?3. How can we demonstrate the other benefits of web accessibility?4. Can we consider "providing access" as the baseline for web accessibility?5. What needs to be done to turn web accessibility from an afterthought to something that is done proactively? 2/23
  3. 3. Why does this matter?• Guide and help in better teaching web accessibility;• Better communicate the meaning of the concept;• Advance web accessibility as a research field by providing a shared understanding;• Improve penetration of web accessibility into commercial and industrial settings. 3/23
  4. 4. How did we investigate this? 4/23
  5. 5. What did we find?• Definitions by standardisation/regulatory bodies have higher acceptance.• People are led by the social aspect of accessibility.• Forcing people does not engage on accessibility.• Empirical research is needed on demonstrating how accessibility benefits all.• Different understandings of web accessibility can generate tension.• A definition has to be realistic, concise, be proactive and refer to different contexts and user groups. 5/23
  6. 6. The survey: Demographics (Part 1) 6/23
  7. 7. The survey: Questionnaire (Part 2)D1 Web accessibility means that people with disabilities can use the Web. More specifically, Web accessibility means that people with disabilities can perceive, understand, navigate and interact with the Web, and that they can contribute to the web [W3C WAI].D2 Technology is accessible if it can be used as effectively by people with disabilities as by those without [SECTION 508].D3 The extent to which a product website can be used by specified users with specified disabilities to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use [ISO].D4 A website is accessible if it is effective, efficient and satisfactory for more people in more situations [Thatcher et al, Constructing Accessible Websites].D5 The removal of all technical barriers to effective interaction. 7/23

  17. 17. Interest/Motivation 17/23
  18. 18. Interest/Motivation• Specialisation – “Designing better products” is the principle reason why engineers embrace accessibility. – Very few designers are forced to do web accessibility.• Education – Business people did not specify increasing revenue as their main motivation.• Role – Majority of consultants, practitioners, managers, researchers agree on social reasons (ethical and inclusion) – Researchers are the least interested in ethical reasons.• Work – Complying with law is quite low in industry and governmental organisations. 18/23

  20. 20. Revisiting….What did we find?• Definitions by standardisation/regulatory bodies have higher acceptance.• People are led by the social aspect of accessibility.• Forcing people does not engage on accessibility.• Empirical research is needed on demonstrating how accessibility benefits all.• Different understandings of web accessibility can generate tension.• A definition has to be realistic, concise, be proactive and refer to different contexts and user groups. 20/23
  21. 21. Future Research• Investigate statements and their relationships with definitions and motivations. – Relationship between accessibility and usability; – Accessibility for all vs. for disabled people; – Web accessibility vs. user experience; – Inclusion vs exclusion, etc.• How do people who are not in the field perceive web accessibility? 21/23
