• Multi-Layered Interfaces to Improve Older Adults' Initial Learnability of Mobile Applications

  Rock Leung, Leah Findlater, Joanna McGrenere, Peter Graf, Justine Yang · 2010 · ACM Transactions on Accessible Computing

  This paper investigates whether multi-layered (ML) interfaces can improve the learnability of mobile applications for older adults. ML interfaces present novice users with a simplified, reduced-functionality layer containing only basic features, allowing them to progress to a…

• Exploring Methods to Improve Pen-Based Menu Selection for Younger and Older Adults

  Karyn Moffatt, Joanna McGrenere · 2009 · ACM Transactions on Accessible Computing

  This study investigates why users struggle with pen-based menu selection on tablet PCs, particularly older adults, and tests two approaches for reducing errors. Building on a baseline study that identified three error types (slipping, drifting, and "missing just below"), the…

• 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…

• Strategic Design for Users with Diabetic Retinopathy: Factors Influencing Performance in a Menu-Selection Task

  Paula J. Edwards, Leon Barnard, V. Kathlene Emery, Ji Soo Yi, Kevin P. Moloney, Thitima Kongnakorn, Julie A. Jacko, François Sainfort, Pamela R. Oliver, Joseph Pizzimenti, Annette Bade, Greg Fecho, Josephine Shallo-Hoffmann · 2004 · Proceedings of the 6th International ACM SIGACCESS Conference on Computers and Accessibility (Assets 04)

  This paper examines how interface design features affect menu selection performance for users with Diabetic Retinopathy (DR), a progressive eye condition affecting 40-45% of the approximately 18 million Americans with diabetes. The study involved 25 volunteers from Nova…
