Blind and low-vision (BLV) employees in mixed-visual ability teams often encounter information (e.g., PDFs, diagrams) in inaccessible formats. To enable teamwork, teams must transf…
Speech-based Mark for Data Sonification
Yichun Zhao, Jingyi Lu, Miguel A Nacenta
Sonification serves as a powerful tool for data accessibility, especially for people with vision loss. Among various modalities, speech is a familiar means of communication similar…
TADA: Making Node-link Diagrams Accessible to Blind and Low-Vision People
Yichun Zhao, Miguel A. Nacenta, Mahadeo A. Sukhai +1
Diagrams often appear as node-link representations in many contexts, such as taxonomies, mind maps and networks in textbooks. Despite their pervasiveness, they present significant…
