• 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…

• Consolidating computer operation and wheelchair control

  Torsten Felzer, Rainer Nordmann · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '07)

  This short ASSETS 2007 demo proposal from Torsten Felzer and Rainer Nordmann at Darmstadt University of Technology describes the integration of two previously separate assistive systems they had built for people with severe physical disabilities. The first, HaMCoS (HAnds-free…

• Alternative Text Entry Using Different Input Methods

  Torsten Felzer, Rainer Nordmann · 2006 · Proceedings of the 8th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '06)

  This paper presents the HaMCoS (Hands-free Mouse Control System) framework and its text entry applications, designed for people who cannot use their hands to operate a keyboard. HaMCoS works by detecting intentional muscle contractions — specifically single (CE1) and double…
