Spatial Organization Is Accessibility Structure: Hierarchical Screen Reading of Mobile UIs
Yongxiang Hu, Xuan Wang, Qingyang Qiu +5
Screen readers for blind and low-vision (BLV) users flatten mobile UIs into a linear sequence. Modern mobile UIs, however, contain dozens of elements grouped by spatial layout. Suc…
