Scene Reading

An interaction paradigm that extends touch-based screen reading concepts from 2-D interfaces to 3-D virtual environments, enabling blind and low vision users to explore virtual scenes nonvisually. Scene reading provides semantic information about virtual objects and their spatial positions through touch gestures and spatial audio. Users can drag their finger across a touchscreen to identify objects (spatial reading), flick through objects sequentially (sequential reading), or trace a circle to hear all visible objects (overview reading). The concept bridges familiar mobile screen reader interactions with the demands of immersive 3-D content.
