• Interactive SIGHT into Information Graphics

  Seniz Demir, David Oliver, Edward Schwartz, Stephanie Elzer, Sandra Carberry, Kathleen F. McCoy · 2010 · Proceedings of the 2010 International Cross Disciplinary Conference on Web Accessibility (W4A)

  This paper presents Interactive SIGHT (Summarizing Information GrapHics Textually), a system that provides visually impaired users with access to the high-level knowledge conveyed by bar charts in electronic documents. Unlike approaches that simply reproduce the graphic in…

• 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 different populations. Most…

• Multimodal Presentation of Two-Dimensional Charts: An Investigation Using Open Office XML and Microsoft Excel

  Iyad Abu Doush, Enrico Pontelli, Tran Cao Son, Dominic Simon, Ou Ma · 2010 · ACM Transactions on Accessible Computing

  This paper presents a comprehensive system for making Microsoft Excel charts accessible to people who are blind or visually impaired through multimodal haptic and audio feedback. The system extracts chart data from the OOXML format introduced in Excel 2007, then presents it…

• Interactive SIGHT Demo: Textual Summaries of Simple Bar Charts

  Seniz Demir, David Oliver, Edward Schwartz, Stephanie Elzer, Sandra Carberry, Kathleen F. McCoy · 2010 · Proceedings of the 12th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2010)

  This demonstration paper presents Interactive SIGHT, a browser extension designed to make simple bar charts found in online popular media (newspapers, magazines) accessible to people with visual impairments. The system goes beyond providing raw data values — it identifies the…

• Understanding the Challenges and Opportunities for Richer Descriptions of Stereotypical Behaviors of Children with ASD: A Concept Exploration and Validation

  Fnu Nazneen, Fatima A. Boujarwah, Shone Sadler, Amha Mogus, Gregory D. Abowd, Rosa I. Arriaga · 2010 · Proceedings of the 12th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2010)

  This paper from Georgia Institute of Technology explores the concept of a wearable sensor system that can tacitly collect contextual data — physiological state, environmental conditions, and location — and map it to occurrences of stereotypical behaviours in children with autism…
