• Affordable Web Accessibility: A Case for Cheaper ARIA

  Yury Puzis, Yevgen Borodin, Andrii Soviak, Valentyn Melnyk, I. V. Ramakrishnan · 2015 · Proceedings of the 12th International Web for All Conference (W4A)

  This paper argues that the primary barrier to web accessibility is not technical limitations but the high cost of implementing WAI-ARIA, the W3C accessibility specification for rich internet applications. The authors systematically analyze why ARIA implementation is expensive by…
