• A Comparison of Touchscreen and Mouse for Real-World and Abstract Tasks with Older Adults

  Sung-Hee Kim, Kailun Zhang, Joanna McGrenere, Kellogg S. Booth, Claudia Jacova · 2020 · ACM Transactions on Accessible Computing

  This study investigates whether input device choice (touchscreen vs. mouse) affects performance on computerized cognitive tests for older adults, with implications for the C-TOC (Cognitive Testing on Computer) project developing self-administered online cognitive screening. As…

• Designing an Adaptive Web Navigation Interface for Users with Variable Pointing Performance

  Aqueasha Martin-Hammond, Foad Hamidi, Tejas Bhalerao, Christian Ortega, Abdullah Ali, Catherine Hornback, Casey Means, Amy Hurst · 2018 · Proceedings of the 15th International Web for All Conference (W4A)

  This paper investigates how to design adaptive web navigation interfaces for people who experience variable pointing ability — difficulty using a mouse to click targets on screen that fluctuates over time due to conditions like early-stage Parkinson's disease, age-related…

• Who Should Have Access to my Pointing Data? Privacy Tradeoffs of Adaptive Assistive Technologies

  Foad Hamidi, Kellie Poneres, Aaron Massey, Amy Hurst · 2018 · Proceedings of the 20th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2018)

  This UMBC study examines the often-overlooked privacy tradeoffs inherent in Adaptive Assistive Technologies (AATs) — software systems that monitor user performance data to automatically adapt their functionality. While AATs offer significant usability benefits for people whose…

• 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…

• Goal Crossing with Mice and Trackballs for People with Motor Impairments: Performance, Submovements, and Design Directions

  Jacob O. Wobbrock, Krzysztof Z. Gajos · 2008 · ASSETS '08: Proceedings of the 10th International ACM SIGACCESS Conference on Computers and Accessibility

  This study investigates whether goal crossing—an input technique where users move through a target boundary rather than clicking within it—can benefit people with motor impairments. The research compares crossing performance against traditional area pointing using a rigorous…

• Understanding Pointing Problems in Real World Computing Environments

  Amy Hurst, Jennifer Mankoff, Scott E. Hudson · 2008 · Proceedings of the 10th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '08)

  This paper develops techniques for collecting and analysing pointing performance data during real-world computer use, rather than solely in laboratory settings, to understand how pointing behaviour varies over time for individuals with motor impairments. Two computers were…
