• GraVVITAS 2.0: A Framework For Digital Accessible Content Provision

  Cagatay Goncu, Kim Marriott · 2019 · Proceedings of the 21st International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2019)

  This demonstration paper presents GraVVITAS 2.0 (Graphics Viewer using Vibration Interactive Touch and Speech), a framework for making graphical information accessible to people with vision impairments on off-the-shelf mobile devices. The paper argues that while screen readers…

• Producing Accessible Statistics Diagrams in R

  Donal Fitzpatrick, A. Jonathan R. Godfrey, Volker Sorge · 2017 · Proceedings of the 14th International Web for All Conference (W4A)

  This paper presents a system for making statistical diagrams accessible to blind users by generating semantically enriched SVG graphics from the R statistical computing environment. The core problem is that statistical graphics — bar charts, histograms, box plots, scatter plots,…

• ChattyBooks and ChattyBook Service

  Masakazu Suzuki, Katsuhito Yamaguchi · 2017 · Proceedings of the 14th International Web for All Conference (W4A)

  This demonstration paper presents ChattyBooks, a Windows application that converts STEM content in DAISY/accessible EPUB3 format into audio-embedded HTML5 with JavaScript, enabling playback in any web browser on any platform without requiring specialized DAISY/EPUB3 players. The…

• Accessible Map Visualization Prototype

  Tania Calle-Jimenez, Sergio Luján-Mora · 2016 · Proceedings of the 13th International Web for All Conference (W4A)

  This paper from Ecuador's National Polytechnic School and the University of Alicante presents a prototype for making online geographic maps accessible to people with visual disabilities. The authors identify four key accessibility barriers in web-based maps: maps rendered as…

• End-to-End Solution for Accessible Chemical Diagrams

  Volker Sorge, Mark Lee, Sandy Wilkinson · 2015 · Proceedings of the 12th International Web for All Conference (W4A)

  This paper presents a complete pipeline for making chemical diagrams — typically distributed as inaccessible bitmap images — fully accessible on the web. The system takes bitmap images of molecular diagrams as input and produces interactive, explorable SVG diagrams with semantic…

• Accessible On-line Graphics

  Anuradha Madugalla · 2015 · Proceedings of the 12th International Web for All Conference (W4A)

  This doctoral consortium paper proposes semi-automated methods for transcribing online graphics — particularly floor plans — into accessible formats for blind users. The research is motivated by the fundamental problem that screen readers and voice synthesisers can only process…

• GraSSML: Accessible Smart Schematic Diagrams for All

  Z. Ben Fredj, D. A. Duce · 2006 · Proceedings of the 2006 International Cross-Disciplinary Workshop on Web Accessibility (W4A)

  This paper addresses a persistent gap in web accessibility: making schematic diagrams (organizational charts, flowcharts, UML diagrams, etc.) accessible to people who cannot perceive visual representations. While previous approaches tried to work "bottom-up" — starting with a…
