• 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,…

• Mouse Movements of Motion-Impaired Users: A Submovement Analysis

  Faustina Hwang, Simeon Keates, Patrick Langdon, John Clarkson · 2003 · Proceedings of the 6th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '04)

  This paper presents a detailed submovement analysis of mouse cursor trajectories from six motion-impaired users (four with cerebral palsy of varying types — athetoid, athetoid with spasm, and general — and one with Friedrich's ataxia and tremor) and three able-bodied controls…

• 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…

• Image Pre-Compensation to Facilitate Computer Access for Users with Refractive Errors

  Miguel Alonso, Armando Barreto, J. Gualberto Cremades · 2003 · Proceedings of the 6th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '04)

  This paper presents a novel approach to improving computer access for people with refractive visual errors by pre-compensating displayed images using knowledge of the user's specific optical aberration. The core insight is that the human eye can be modelled as a Linear Time…

• visiBabble for Reinforcement of Early Vocalization

  Harriet Fell, Cynthia Cress, Joel MacAuslan, Linda Ferrier · 2003 · Proceedings of the 6th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '04)

  This paper presents visiBabble, a real-time system that detects syllable-like vocalizations in infant babbling and responds with brightly coloured animations as visual reinforcement. The system targets infants at risk for speech impairments due to conditions such as cerebral…

• 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…

• MEMOS: An Interactive Assistive System for Prospective Memory Deficit Compensation — Architecture and Functionality

  Hendrik Schulze · 2003 · Proceedings of the 6th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '04)

  This paper presents MEMOS (Mobile Extensible Memory Aid System), a distributed electronic memory aid designed to compensate for prospective memory deficits following brain injury. Prospective memory — the ability to remember future intentions and tasks — is a frequent and…
