A guided conversation about the accessibility support baseline and an opportunity to find out what others are supporting and to share thoughts and experiences. The support baseline is the term WCAG uses for the set of user technologies that an application is expected to work with, specifically the combinations of assistive technology (AT), operating system (OS) and where relevant browser and device. WCAG doesn’t define what needs to be in the baseline because it depends on your users, and on the technologies available to them.
Is testing only one combination for web and one for mobile sufficient? Changes in desktop screen reader usage, mobile fragmentation, and frequent updates to OS and AT may mean that it isn’t. But there are hundreds if not thousands of potential combinations. How do we balance support for these combinations against testing effort?
We will discuss:
• Who or what does a baseline impact?
• Variables to account for in a baseline
• Effort and costs
• Assistive Technology usage data
• Organizational challenges to supporting AT
• Sample web and mobile support baselines.
