Helping Visually Impaired Users Properly Aim a Camera
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…

Follow That Sound: Using Sonification and Corrective Verbal Feedback to Teach Touchscreen Gestures
This paper proposes and evaluates two techniques for teaching touchscreen gestures to users with visual impairments: gesture sonification (mapping finger position to audio using pitch for the y-axis and stereo panning for the x-axis) and corrective v…
