• 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…

• 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-Au…
