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…
