• FluxMarker: Enhancing Tactile Graphics with Dynamic Tactile Markers

  Ryo Suzuki, Abigale Stangl, Mark D. Gross, Tom Yeh · 2017 · Proceedings of the 19th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '17)

  This paper presents FluxMarker, an inexpensive and scalable system that adds dynamic, movable tactile markers on top of static raised-line tactile graphics. Traditional embossed tactile graphics are static and cannot represent changing data, while existing refreshable braille…

• Consistency of a Tactile Pattern Set

  Denise Prescher, Jens Bornschein, Gerhard Weber · 2017 · ACM Transactions on Accessible Computing

  This paper addresses a fundamental challenge in tactile graphics production: how to create fill patterns that remain recognizable and distinguishable across different production media with varying resolutions. The three media studied were microcapsule (swell) paper (>20 dpi),…

• 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…
