• Distinguishing Users By Pointing Performance in Laboratory and Real-World Tasks

  Amy Hurst, Scott E. Hudson, Jennifer Mankoff, Shari Trewin · 2013 · ACM Transactions on Accessible Computing

  This paper investigates how machine learning can automatically assess pointing difficulties from everyday computer use, addressing a critical barrier to accessible computing: the lack of frequent, low-cost assessment of pointing ability. The researchers collected and analyzed…

• Effects of Target Expansion on Selection Performance in Older Computer Users

  Faustina Hwang, Nic Hollinworth, Nitin Williams · 2013 · ACM Transactions on Accessible Computing

  This research investigates target expansion as an assistive technique for improving mouse pointing performance in older computer users. Target expansion dynamically enlarges clickable targets as the cursor approaches, conserving screen space while providing larger click areas…

• Visual Complexity, Player Experience, Performance and Physical Exertion in Motion-Based Games for Older Adults

  Jan Smeddinck, Kathrin M. Gerling, Saranat Tiemkeo · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '13)

  This paper investigates how visual complexity (graphical fidelity) affects player experience, in-game performance, and physical exertion in motion-based games designed for older adults. The study is motivated by the growing use of kinesiatric serious games (KSGs) in physical…

• What Health Topics Older Adults Want to Track: A Participatory Design Study

  Jennifer L. Davidson, Carlos Jensen · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '13)

  This paper presents a participatory design study investigating what health topics older adults (aged 65+) want to track using mobile health (mHealth) applications. The authors argue that most mHealth app developers fail to conduct needs assessments with older adult end users,…

• Web Accessibility for Older Adults: Effects of Line Spacing and Text Justification on Reading Web Pages

  Helen Petrie, Sorachai Kamollimsakul, Christopher Power · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This poster paper empirically tests two common web accessibility recommendations for older adults: increased line spacing and left-only text justification. The authors note that at least 10 sets of guidelines for making websites accessible to older people exist in English alone,…

• Wheelchair-Based Game Design for Older Adults

  Kathrin M. Gerling, Regan L. Mandryk, Michael R. Kalyn · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This paper addresses the design of motion-based video games that are accessible to institutionalized older adults using wheelchairs. More than half of Canadians over 65 in residential care use wheelchairs, and wheelchair use severely limits opportunities for physical activity…

• A Haptic ATM Interface to Assist Visually Impaired Users

  Brendan Cassidy, Gilbert Cockton, Lynne Coventry · 2013 · Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS)

  This paper presents the design and evaluation of a haptic interface for ATM keypads that conveys directional information to visually impaired users without relying on audio or visual output. Current ATM accessibility primarily uses audio lead-through via headphones, which has…
