• Haptic 3D Surface Representation of Table-Based Data for People With Visual Impairments

  Jonas Braier, Katharina Lattenkamp, Benjamin Räthel, Sandra Schering, Michael Wojatzki, Benjamin Weyers · 2014 · ACM Transactions on Accessible Computing

  This paper introduces "relief charts"—3D surface representations of standard data visualizations (bar graphs, pie charts, scatter plots, radar charts) designed to make complex tabular data accessible to people with visual impairments. The approach is grounded in neuroscientific…

• Tactile Graphics with a Voice: Using QR Codes to Access Text in Tactile Graphics

  Catherine M. Baker, Lauren R. Milne, Jeffrey Scofield, Cynthia L. Bennett, Richard E. Ladner · 2014 · ASSETS '14: Proceedings of the 16th International ACM SIGACCESS Conference on Computers & Accessibility

  This paper presents Tactile Graphics with a Voice (TGV), a system that makes text labels in tactile graphics accessible by replacing Braille labels with QR codes that can be scanned and read aloud using a smartphone. The motivation is significant: while tactile graphics are…

• New Tools for Automating Tactile Geographic Map Translation

  Nizar Bouhlel, Anis Rojbi · 2014 · Proceedings of the 16th International ACM SIGACCESS Conference on Computers & Accessibility (ASSETS)

  This demo paper presents a Matlab-based software tool that semi-automates the conversion of visual geographic maps into tactile versions suitable for blind students. Tactile graphics are the most effective modality for blind people to comprehend graphical images, but converting…

• Tactile Aids for Visually Impaired Graphical Design Education

  Samantha McDonald, Joshua Dutterer, Ali Abdolrahmani, Shaun K. Kane, Amy Hurst · 2014 · Proceedings of the 16th International ACM SIGACCESS Conference on Computers & Accessibility (ASSETS 2014)

  This demonstration paper describes the creation of over 10 tactile aids using laser cutting and 3D printing to make graphic design theory accessible to a visually impaired student enrolled in an introduction to human-centered computing class at UMBC. The course unit covered…

• Evaluation of Non-Visual Panning Operations Using Touch-Screen Devices

  HariPrasath Palani, Nicholas A. Giudice · 2014 · Proceedings of the 16th International ACM SIGACCESS Conference on Computers & Accessibility (ASSETS 2014)

  This demonstration paper addresses a critical challenge in non-visual access to graphical information on touchscreens: how to pan across large-format graphics (maps, floor plans) without losing spatial orientation. The authors built on their Vibro-Audio Interface (VAI), which…

• Tactile Graphics with a Voice Demonstration

  Catherine M. Baker, Lauren R. Milne, Jeffrey Scofield, Cynthia L. Bennett, Richard E. Ladner · 2014 · Proceedings of the 16th International ACM SIGACCESS Conference on Computers & Accessibility (ASSETS '14)

  This demonstration paper presents Tactile Graphics with a Voice (TGV), a system that makes labels on tactile graphics accessible to blind and low vision users who do not read Braille. STEM textbooks are filled with images — from parabolas to cell diagrams — that are essential…

• Tracking @stemxcomet: Teaching Programming to Blind Students via 3D Printing, Crisis Management, and Twitter

  Shaun K. Kane, Jeffrey P. Bigham · 2014 · ACM Technical Symposium on Computer Science Education

  This paper describes the design and execution of a four-day programming workshop for blind and visually impaired high school students, conducted as part of the National Federation of the Blind's STEM-X summer science camp. Nine students (grades 8-12) learned Ruby programming…
