• A Usability Study of Nomon: A Flexible Interface for Single-Switch Users

  Nicholas Bonaker, Emli-Mari Nel, Keith Vertanen, Tamara Broderick · 2023 · Proceedings of the 25th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2023)

  This paper presents the first usability study of Nomon — an alternative single-switch interface — with actual motor-impaired users, comparing it against the widely used row-column scanning (RCS) method. Single-switch interfaces are essential communication tools for people with…

• Co-designing new keyboard and mouse solutions with people living with motor impairments

  Rodolfo Cossovich, Steve Hodges, Jin Kang, Audrey Girouard · 2023 · Proceedings of the 25th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2023)

  This short paper describes a co-design process for developing accessible alternatives to traditional keyboard and mouse interfaces, conducted in collaboration with people living with motor impairments. The study involved three phases: an initial survey of 42 people with physical…

• Accuracy and Reliability of At-Home Quantification of Motor Impairments Using a Computer-Based Pointing Task with Children with Ataxia-Telangiectasia

  Vineet Pandey, Nergis C. Khan, Anoopum S. Gupta, Krzysztof Z. Gajos · 2023 · ACM Transactions on Accessible Computing

  This paper validates at-home, unsupervised use of Hevelius, a web-based active digital phenotyping system that quantifies motor impairment in the dominant arm through mouse pointing tasks. The study addresses a critical gap: while prior research showed that crowdsourced…
