• 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…

• Principles for Designing Large-Format Refreshable Haptic Graphics Using Touchscreen Devices: An Evaluation of Nonvisual Panning Methods

  Hari Prasath Palani, Nicholas A. Giudice (2017) — ACM Transactions on Accessible Computing

  This paper addresses a fundamental challenge in touchscreen-based accessibility: how to provide non-visual access to large-format graphical materials like maps that exceed the device's screen size. While touchscreens represent the fastest-growing com…
