• Learning Non-Visual Graphical Information Using a Touch-Based Vibro-Audio Interface

  Nicholas A. Giudice, Hari Prasath Palani, Eric Brenner, Kevin M. Kramer (2012) — Proceedings of the 14th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2012)

  This paper evaluates a vibro-audio interface on a commercial Samsung Galaxy tablet that provides non-visual access to graphical information through synchronized vibration and audio feedback triggered by touch exploration. When users trace their finge…

• Exploring New Paradigms for Accessible 3D Printed Graphs

  Michele Hu (2015) — ASSETS '15: Proceedings of the 17th International ACM SIGACCESS Conference on Computers & Accessibility

  This paper explores novel approaches to representing bar graphs for blind users using 3D printing technology, moving beyond traditional flat tactile graphics. Traditional tactile graphics (created with swell paper, embossers, or thermoform) use raise…
