• Audio-Based Feedback Techniques for Teaching Touchscreen Gestures

  Uran Oh, Stacy Branham, Leah Findlater, Shaun K. Kane · 2015 · ACM Transactions on Accessible Computing (TACCESS)

  This paper proposes and evaluates two complementary audio-based techniques for teaching touchscreen gestures to blind and low-vision users: gesture sonification (mapping finger position to pitch and stereo panning to create an audio representation of the gesture) and corrective…

• Using Dynamic Audio Feedback to Support Peripersonal Reaching in Visually Impaired People

  Graham Wilson, Stephen A. Brewster · 2015 · ASSETS '15: Proceedings of the 17th International ACM SIGACCESS Conference on Computers & Accessibility

  This demonstration paper explores how dynamic audio feedback can help blind and visually impaired people locate and reach for objects in their immediate (peripersonal) space. The research addresses an important developmental challenge: blind children engage less with objects in…

• Helping Visually Impaired Users Properly Aim a Camera

  Marynel Vázquez, Aaron Steinfeld · 2012 · Proceedings of the 14th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2012)

  This paper evaluates three interaction modes for helping visually impaired users aim a camera to achieve good photo composition: speech-based feedback (spoken directional words like "up", "down", "left", "right" with pitch indicating proximity), tone-based feedback (a looping…
