• The Audio Abacus: Representing Numerical Values with Nonspeech Sound for the Visually Impaired

  Bruce N. Walker, Jeffrey Lindsay, Justin Godfrey · 2003 · Proceedings of the 6th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '04)

  This paper introduces the Audio Abacus, a novel sonification application that transforms exact numerical values into sequences of non-speech tones, following the analogy of a physical abacus where each digit is represented by a distinct sound. Unlike most sonification research,…

• Accessibility Designer: Visualizing Usability for the Blind

  Hironobu Takagi, Chieko Asakawa, Kentarou Fukuda, Junji Maeda · 2003 · Proceedings of the 6th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '04)

  This paper from IBM's Tokyo Research Laboratory presents Accessibility Designer (aDesigner), a tool that goes beyond conventional accessibility checkers by visualising the usability of web pages for blind screen reader users rather than merely checking HTML compliance. The…

• Evaluation of a Non-Visual Molecule Browser

  Andy Brown, Steve Pettifer, Robert Stevens · 2003 · Proceedings of the 6th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '04)

  This paper evaluates Kekulé, software designed to allow visually impaired users to explore chemical molecular structures — diagrams that are typically presented as two-dimensional graph schematics showing atoms (nodes) connected by bonds (edges). Molecular diagrams are an…

• Design and Development of an Indoor Navigation and Object Identification System for the Blind

  Andreas Hub, Joachim Diepstraten, Thomas Ertl · 2003 · Proceedings of the 6th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '04)

  This paper presents a multi-sensor orientation assistant for blind users navigating unknown indoor environments. The system addresses three core problems identified by blind users: determining one's position, determining head direction and movement direction, and identifying…
