• Making the Web Easier to See with Opportunistic Accessibility Improvement

  Jeffrey P. Bigham · 2014 · ACM Symposium on User Interface Software and Technology

  This paper introduces the concept of "opportunistic accessibility improvement" — the idea that accessibility enhancements like magnification should be automatically applied to the maximum extent possible without causing negative side effects. The author implements this concept…

• Note-Taker 2.0: The Next Step Toward Enabling Students who are Legally Blind to Take Notes in Class

  David S. Hayden, Liqing Zhou, Michael J. Astrauskas, John A. Black · 2010 · Proceedings of the 12th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2010)

  This paper describes the iterative design and usability testing of the Note-Taker, a portable assistive device that enables students who are legally blind to take notes during classroom lectures. The core problem is that note-taking requires rapidly switching between a far-sight…
