• Towards A Universally Usable Human Interaction Proof: Evaluation of Task Completion Strategies

  Graig Sauer, Jonathan Lazar, Harry Hochheiser, Jinjuan Feng · 2010 · ACM Transactions on Accessible Computing

  This paper addresses a critical accessibility barrier: CAPTCHAs and human-interaction proofs (HIPs) that effectively lock people with visual impairments out of web services. Prior research showed that blind users could only solve audio CAPTCHAs about 43-46% of the time, far…
