Abstract

The equality of access – accessibility – is difficult to quantify, define, or agree upon. Our previous work analysed the responses of web accessibility specialists in regard to a number of pre-defined definitions of accessibility. While uncovering much, this analysis did not allow us to quantify the communities’ understanding of the relationship accessibility has with other domains and assess how the community scopes accessibility. In this case, we asked over 300 people, with an interest in accessibility, to answer 33 questions surrounding the relationship between accessibility, user experience (UX), and usability; inclusion and exclusion; and evaluation, in an attempt to harmonise our understanding of web accessibility. We found that respondents think that accessibility and usability are highly related and also think that accessibility is applicable to everyone and not just people with disabilities. Respondents strongly agree that accessibility must be grounded on user-centred practices and that accessibility evaluation is more than just inspecting source code; however, they are divided as to whether training in ‘Web Content Accessibility Guidelines’ is necessary or not to assess accessibility. These perceptions are important for usability and UX professionals, developers of automated evaluation tools, and those practitioners running website evaluations.

Notes

This study aims to better understand the concept of accessibility. Researchers conducted a survey, asking more than 300 participants their views and definitions of accessibility. They were aiming at harmonizing understandings of the concept and better supporting users who were outside the community. They survey consisted of 33 questions assessing participants' demographics, definitions and perceptions of accessibility, and a total number of 300 people provided complete responses. Results indicated that participants, especially technical participants, perceived accessibility and usability to be dependent. Most people, especially technical participants, perceived improving accessibility not only benefited disabled people, but also benefit the general audience. All participants agreed that accessibility testing should be user-centred. Thus assessing a webpage's accessibility should rely on users' subjective perceptions. In general, participants were more in favor of having a standard definition for accessibility.
