• AudioGraf: A Diagram-Reader for the Blind

  Andrea R. Kennel (1996) — Proceedings of the Second Annual ACM Conference on Assistive Technologies (Assets '96)

  This paper from ETH Zürich presents AudioGraf, a system that enables blind and visually impaired users to read diagrams through a combination of touch panel input and auditory display. The core problem addressed is that diagrams — widely used in tech…

• Constructing Relational Diagrams in Audio: The Multiple Perspective Hierarchical Approach

  Oussama Metatla, Nick Bryan-Kinns, Tony Stockman (2008) — Proceedings of the 10th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '08)

  This paper from Queen Mary, University of London presents a novel approach for constructing and manipulating relational diagrams — such as Entity-Relationship (ER) diagrams — through an audio-only interface. While previous research addressed non-visu…

• Designing Auditory Cues to Enhance Spoken Mathematics for Visually Impaired Users

  Emma Murphy, Enda Bates, Dónal Fitzpatrick (2010) — Proceedings of the 12th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2010)

  This paper presents a novel auditory math system designed to make spoken mathematical equations more accessible to visually impaired users. The core challenge addressed is that visual mathematical notation conveys structure — such as fractions, super…

• Auditory Displays for Accessible Fantasy Sports

  Jared M. Batterman, Jonathan H. Schuett, Bruce N. Walker (2013) — Proceedings of the 15th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '13)

  This short paper addresses the inaccessibility of online fantasy sports platforms for visually impaired users and presents an accessible fantasy football system built around auditory display techniques. Fantasy sports are a major social and recreatio…

• Universal Design of Auditory Graphs: A Comparison of Sonification Mappings for Visually Impaired and Sighted Listeners

  Bruce N. Walker, Lisa M. Mauney (2010) — ACM Transactions on Accessible Computing

  This study investigates whether auditory graphs—using sound to represent data for people who cannot see visual graphs—can be designed universally for both sighted and visually impaired users, or whether different sonification mappings are needed for …

• Spotlights and Soundscapes: On the Design of Mixed Reality Auditory Environments for Persons with Visual Impairment

  Keenan R. May, Brianna J. Tomlinson, Xiaomeng Ma, Phillip Roberts, Bruce N. Walker (2020) — ACM Transactions on Accessible Computing

  This paper explores the design of information-rich mixed reality (MR) auditory environments to help people with visual impairments form cognitive maps of unfamiliar indoor spaces. The research contrasts two approaches: soundscapes, where virtual obje…

• Planning Your Journey in Audio: Design and Evaluation of Auditory Route Overviews

  Nida Aziz, Tony Stockman, Rebecca Stewart (2022) — ACM Transactions on Accessible Computing

  This research develops and evaluates an auditory route overview system that enables blind users to preview walking routes before embarking on journeys. The system addresses a critical gap: while many navigation aids support live guidance, few tools a…
