• The Crowd Work Accessibility Problem

  Saiganesh Swaminathan, Kotaro Hara, Jeffrey P. Bigham (2017) — Proceedings of the 14th International Web for All Conference (W4A)

  This paper examines a largely overlooked accessibility problem: the inaccessibility of crowdsourcing tasks themselves. While crowd work platforms like Amazon Mechanical Turk (AMT) offer potential employment benefits for people with disabilities — fle…
