• Multimodal Trajectory Playback for Teaching Shape Information and Trajectories to Visually Impaired Computer Users

  Andrew Crossan, Stephen Brewster · 2008 · ACM Transactions on Accessible Computing (TACCESS)

  This research investigates how haptic (force-feedback) and audio trajectory playback can teach shapes and gestures to blind and visually impaired computer users. The fundamental challenge addressed is that spatial information—shapes, diagrams, graphs, maps—is difficult to convey…

• Haptic comparison of size (relative magnitude) in blind and sighted people

  Sarah A. Douglas, Shasta Willson · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '07)

  Douglas and Willson's Assets '07 paper is a controlled psychophysical study of how blind and sighted users compare relative magnitude using a PHANToM force-feedback device — the workhorse haptic input-output device of the era. The motivating problem is practical: accessibility…

• Multimodal Virtual Reality Versus Printed Medium in Visualization for Blind People

  Wai Yu, Stephen Brewster · 2002 · Proceedings of the Fifth International ACM Conference on Assistive Technologies (Assets '02)

  This paper presents a comparative evaluation of two approaches for making bar chart data accessible to blind and visually impaired people: traditional raised tactile diagrams and a multimodal virtual reality system. The VR system combines a SensAble PHANToM force feedback device…

• Cursor Measures for Motion-Impaired Computer Users

  Simeon Keates, Faustina Hwang, Patrick Langdon, P. John Clarkson, Peter Robinson · 2002 · Proceedings of the Fifth International ACM Conference on Assistive Technologies (Assets '02)

  This paper systematically analyses cursor movement patterns of motion-impaired computer users to understand the specific difficulties they face with point-and-click interactions in graphical user interfaces. The authors argue that existing cursor measures, primarily developed by…

• Constructive Exploration of Spatial Information by Blind Users

  Jochen Schneider, Thomas Strothotte · 2000 · Proceedings of the Fourth International ACM Conference on Assistive Technologies (Assets '00)

  This paper from the University of Magdeburg introduces "constructive exploration," a novel approach to helping blind people learn spatial layouts by actively building physical representations of routes and areas using building blocks, guided by an interactive computer system.…
