• Implementing Ability-Based Design: A Systematic Approach to Conceptual User Modeling

  Amelie Nolte, Jacob Wobbrock, Torben Volkmann, Nicole Jochems · 2022 · ACM Transactions on Accessible Computing

  This paper addresses a critical gap in Ability-Based Design (ABD): while the concept has been influential in accessibility research for over a decade, it has lacked a systematic methodology for implementation. ABD, introduced by Wobbrock et al., shifts the design question from…

• Modeling Expertise in Assistive Navigation Interfaces for Blind People

  Eshed Ohn-Bar, João Guerreiro, Dragan Ahmetovic, Kris M. Kitani, Chieko Asakawa · 2018 · Proceedings of the 23rd International Conference on Intelligent User Interfaces (IUI)

  This short IUI paper asks a question most assistive-navigation research leaves unasked: what happens as a blind user becomes an expert on a route? Existing smartphone guidance apps deliver the same instruction set on a user's tenth trip down a corridor as on their first,…

• Detecting Linguistic HCI Markers in an Online Aphasia Support Group

  Yoram M. Kalman, Kathleen Geraghty, Cynthia K. Thompson, Darren Gergle · 2012 · Proceedings of the 14th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2012)

  This paper investigates whether the language deficits associated with aphasia — an acquired language disorder typically resulting from stroke or brain injury — can be detected in online written communication. The concept of "HCI markers" is introduced: measurable signals…

• A Tool to Promote Prolonged Engagement in Art Therapy: Design and Development from Arts Therapist Requirements

  Jesse Hoey, Krists Zutis, Valerie Leuty, Alex Mihailidis · 2010 · Proceedings of the 12th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2010)

  This paper describes the design and evaluation of a customisable touch-screen tool that assists creative arts therapists working with older adults with dementia. The system uses a partially observable Markov decision process (POMDP) controller to autonomously monitor a client's…

• User Capability in an Adaptive World

  Robert Dodd, Steve Green, Elaine Pearson · 2009 · MSIADU '09: Proceedings of the 1st ACM SIGMM International Workshop on Media Studies and Implementations that Help Improving Access to Disabled Users

  This paper presents a fundamental rethinking of how user profiles should be constructed for adaptive and accessible computing. Published at MSIADU '09 (co-located with ACM Multimedia), it critiques the dominant Access For All standard (ISO/IEC 24751) for conflating user…

• Simulating HCI for Special Needs

  Pradipta Biswas · 2007 · SIGACCESS Accessibility and Computing

  This paper describes the development of a simulator designed to model human-computer interaction for users with physical disabilities, addressing a significant gap in HCI research. The author argues that existing HCI models such as the GOMS family (KLM, CMN-GOMS, CPM-GOMS) and…
