Rich Representations of Visual Content for Screen Reader Users
summary
Proposes a taxonomy and six working prototypes (progressive detail, multimedia alt audio, spatial interaction, structured categories, question-and-answer and hyperlink lookups) and evaluates them with 14 blind screen-reader users. Implements swiping, tapping and audio snippets to fetch variable-detail captions, spatial cues to build a mental map, and crowd/author-supplied answers; users prefer progressive detail for control, spatial for location understanding, and show a bimodal split on multimedia audio. Notes authoring burden and compliance as the main practical barrier.
