  • Measuring Website Usability for Visually Impaired People - A Modified GOMS Analysis

    Henrik Tonn-Eichstädt · 2006 · Proceedings of the 8th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '06)

    This paper adapts the GOMS (Goals, Operators, Methods, Selection rules) model — a well-established HCI method for estimating task execution times — to measure website usability specifically for blind screen reader users. The author argues that accessibility is fundamentally a…

  • Hardware-Based Text-to-Braille Translator

    Xuan Zhang, Cesar Ortega-Sanchez, Iain Murray · 2006 · Proceedings of the 8th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '06)

    This paper describes the implementation of a text-to-Braille translator in hardware using Field-Programmable Gate Arrays (FPGAs), as an alternative to the software-based translators that dominate the market. The translator implements Paul Blenkhorn's algorithm for converting…

  • A Portable Device for the Translation of Braille to Text

    Iain Murray, Andrew Pasquale · 2006 · Proceedings of the 8th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '06)

    This paper presents the development of a portable, handheld device that optically scans embossed Braille and translates it into printed text in real time. The device addresses a significant communication barrier: while many blind and vision-impaired people read and write using…

  • Lambda: A Multimodal Approach to Making Mathematics Accessible to Blind Students

    Alistair D N Edwards, Heather McCartney, Flavio Fogarolo · 2006 · Proceedings of the 8th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '06)

    This paper presents the Lambda System, a European Union-funded project designed to make mathematics accessible to blind students through a multimodal mathematical editor. Mathematics relies heavily on visual two-dimensional notation — fractions are stacked vertically, square…
