  • 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 computing platform among people…

  • 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…
