• 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…

• Eyes-free Exploration of Shapes with Invisible Puzzle

  Andrea Gerino, Lorenzo Picinali, Cristian Bernareggi, Sergio Mascetti · 2015 · ASSETS '15: Proceedings of the 17th International ACM SIGACCESS Conference on Computers & Accessibility

  This paper presents Invisible Puzzle Game, an iPhone application that uses sonification techniques to enable people who are blind or visually impaired to explore shapes on touchscreen devices. Image exploration is fundamental for developing visuospatial skills and STEM…

• 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…

• Towards Large Scale Evaluation of Novel Sonification Techniques for Non Visual Shape Exploration

  Andrea Gerino, Lorenzo Picinali, Cristian Bernareggi, Nicolò Alabastro, Sergio Mascetti · 2015 · ASSETS '15: Proceedings of the 17th International ACM SIGACCESS Conference on Computers & Accessibility

  This paper presents six sonification techniques for exploring shapes on touchscreen devices and evaluates them through Invisible Puzzle, an iPhone application enabling large-scale unsupervised testing. The research addresses a critical need: people who are blind need access to…
