• 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…

• Refreshable tactile graphics applied to schoolbook illustrations for students with visual impairment

  Grégory Petit, Aude Dufresne, Vincent Levesque, Vincent Hayward, Nicole Trudeau · 2008 · Proceedings of the 10th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '08)

  This paper presents research on making schoolbook illustrations accessible to students with visual impairments using a refreshable tactile display system. The system combines the STReSS2 (Stimulator of Tactile Receptors by Skin Stretch), a device that produces tactile feedback…
