• 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 — flexible scheduling, remote…

• In-context Q&A to Support Blind People Using Smartphones

  André Rodrigues, Kyle Montague, Hugo Nicolau, João Guerreiro, Tiago Guerreiro · 2017 · Proceedings of the 19th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '17)

  This paper addresses a pervasive but understudied problem: the daily challenges blind people face when using smartphone applications go far beyond the touchscreen gesture difficulties that most accessibility research focuses on. The researchers conducted workshops with 42 blind…

• Introducing People with ASD to Crowd Work

  Kotaro Hara, Jeffrey P. Bigham · 2017 · Proceedings of the 19th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '17)

  This paper explores whether crowdsourcing platforms like Amazon Mechanical Turk (AMT) can provide viable employment opportunities for adults with Autism Spectrum Disorder (ASD). With an estimated 50-75% unemployment rate among adults with ASD in the U.S., the authors investigate…

• Leveraging Complementary Contributions of Different Workers for Efficient Crowdsourcing of Video Captions

  Yun Huang, Yifeng Huang, Na Xue, Jeffrey P. Bigham · 2017 · CHI Conference on Human Factors in Computing Systems

  This paper presents BandCaption, a crowdsourcing system that combines automatic speech recognition (ASR) with input from diverse crowd workers to efficiently correct video captions. The key insight is that different groups of people — hearing-impaired users, second-language…
