Q&A or Document-Based? The Effects of Interface Type on How Screen Reader Users Access Interconnected Documents
Colleen F. Cipriano, Yichun Zhao, Miguel A. Nacenta +2
Blind and low-vision (BLV) users are increasingly engaging with large language model (LLM) interfaces to access documents, but it is unclear how such systems support or hinder thei…
Semantic Segmentation of Node and Edge Diagrams for Assistive Technology
Michael Cormier, Yichun Zhao, Laura Paul +3
In this paper, we present a novel set of related models for semantic segmentation of node-link diagrams. These diagrams are frequently used to represent mathematical graphs, relati…
Characterization and Effects of CS2 Learning with GenAI, Visualization, and Human Support
Quinton Yong, Anthony Estey, Miguel Nacenta
Generative AI (GenAI) is becoming a widely adopted learning support tool for both students and instructors, as it offers benefits such as personalized tutoring and scaffolded learn…
"If We Had the Information That We Need to Interpret the World Around Us, We Wouldn't Be Disabled:" Barriers and Opportunities in Information Work among Blind and Sighted Colleagues
Yichun Zhao, Miguel A. Nacenta, Mahadeo A. Sukhai +1
Despite recognition of the value of diversity, the way work takes place can fail to support blind or low-vision employees, especially in collaborative work settings. This paper exa…
Locatability and Locatability Robustness of Visual Variables in Single Target Localization
Wei Wei, Miguel A. Nacenta, Michelle F. Miranda +1
Finding a particular object in a display is important for viewers in many visualizations, for example, when reacting to brushing or to a highlighted object. This can be enabled by…
The Impact of Visual Segmentation on Lexical Word Recognition
Matthew Termuende, Kevin Larson, Miguel Nacenta
When a reader encounters a word in English, they split the word into smaller orthographic units in the process of recognizing its meaning. For example, "rough", when split accordin…
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…
Tools and Tasks in Sensemaking: A Visual Accessibility Perspective
Yichun Zhao, Miguel A. Nacenta
Our previous interview study explores the needs and uses of diagrammatic information by the Blind and Low Vision (BLV) community, resulting in a framework called the Ladder of Diag…
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…
The Effectiveness of Interactive Visualization Techniques for Time Navigation of Dynamic Graphs on Large Displays
Alexandra Lee, Daniel Archambault, Miguel A. Nacenta
Dynamic networks can be challenging to analyze visually, especially if they span a large time range during which new nodes and edges can appear and disappear. Although it is straig…
Case Studies and Challenges in Reproducibility in the Computational Sciences
Sylwester Arabas, Michael R. Bareford, Lakshitha R. de Silva +14
This paper investigates the reproducibility of computational science research and identifies key challenges facing the community today. It is the result of the First Summer School…
