• 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…

• Advanced Auditory Menus: Design and Evaluation of Auditory Scroll Bars

  Pavani Yalla, Bruce N. Walker · 2008 · Proceedings of the 10th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '08)

  This paper from the Sonification Lab at Georgia Institute of Technology investigates how to design auditory scrollbars — non-speech sound cues that convey contextual information (menu size, current position) while navigating auditory menus. Visual menus use scrollbars, icons,…

• Constructing Relational Diagrams in Audio: The Multiple Perspective Hierarchical Approach

  Oussama Metatla, Nick Bryan-Kinns, Tony Stockman · 2008 · Proceedings of the 10th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '08)

  This paper from Queen Mary, University of London presents a novel approach for constructing and manipulating relational diagrams — such as Entity-Relationship (ER) diagrams — through an audio-only interface. While previous research addressed non-visual access to existing…
