• Hover or Tap? Supporting Pen-based Menu Navigation for Older Adults

  Karyn Moffatt, Sandra Yuen, Joanna McGrenere · 2008 · Proceedings of the 10th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '08)

  This paper investigates "drifting" — an error specific to pen-based (Tablet PC) interaction where users accidentally hover over an adjacent menu head, causing their intended menu to close and the wrong one to open. This occurs because inductive pen technology tracks the pen…

• Slipping and drifting: using older users to uncover pen-based target acquisition difficulties

  Karyn A. Moffatt, Joanna McGrenere · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '07)

  Moffatt and McGrenere present an empirical study at the University of British Columbia investigating the underlying causes of pen-based target acquisition difficulty on a Tablet PC, with explicit attention to how age affects targeting ability. Thirty-six right-handed…

• Contextual Web Accessibility - Maximizing the Benefit of Accessibility Guidelines

  David Sloan, Andy Heath, Fraser Hamilton, Brian Kelly, Helen Petrie, Lawrie Phipps · 2006 · Proceedings of the 2006 International Cross-Disciplinary Workshop on Web Accessibility (W4A)

  This influential paper challenges the prevailing approach to web accessibility that treats WCAG conformance as the sole measure of success. The authors argue that while guidelines like WCAG are valuable tools, the persistently low levels of web accessibility indicate that…

• Using Think Aloud Protocol with Blind Users: A Case for Inclusive Usability Evaluation Methods

  Sambhavi Chandrashekar, Tony Stockman, Deborah Fels, Rachel Benedyk · 2006 · Proceedings of the 8th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '06)

  This paper examines whether the Think Aloud Protocol (TAP), one of the most widely used usability evaluation methods, can be effectively applied when testing with blind screen reader users. The study involved six vision-impaired students evaluating a website designed to test the…

• Understanding Emotion through Multimedia: Comparison between Hearing-Impaired People and People with Hearing Abilities

  Rumi Hiraga, Nobuko Kato · 2006 · Proceedings of the 8th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '06)

  This paper investigates how hearing-impaired and normal-hearing people recognise emotions conveyed through drum performances and accompanying visual stimuli. The research is part of a larger project to build a "performance enhancement machine" (PEM) — a system that would enable…

• Designing for Dynamic Diversity: Interfaces for Older People

  Peter Gregor, Alan F. Newell, Mary Zajicek · 2002 · Proceedings of the Fifth International ACM Conference on Assistive Technologies (Assets '02)

  This paper argues that mainstream interface design fails older people by assuming a static, "typical" user who is young, fit, and male. The authors identify three broad groups of older computer users: fit older people who do not consider themselves disabled; frail older people…
