• Understanding and Improving Drilled-Down Information Extraction from Online Data Visualizations for Screen-Reader Users

  Ather Sharif, Olivia H. Wang, Alida T. Muongchan, Katharina Reinecke, Jacob O. Wobbrock · 2023 · Proceedings of the 20th International Web for All Conference (W4A)

  This full research paper presents a comprehensive investigation into how screen-reader users (SRUs) extract drilled-down information from online data visualizations, and how the VoxLens tool can be improved to support this process. While prior work on VoxLens focused on holistic…

• Notably Inaccessible — Data Driven Understanding of Data Science Notebook (In)Accessibility

  Venkatesh Potluri, Sudheesh Singanamalla, Nussara Tieanklin, Jennifer Mankoff · 2023 · Proceedings of the 25th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '23)

  This paper presents the first large-scale analysis of the accessibility of computational notebooks — interactive documents combining code, text, and data visualizations that have become the standard tool for data science work. The researchers analyzed 100,000 Jupyter notebooks…

• Cripping Data Visualizations: Crip Technoscience as a Critical Lens for Designing Digital Access

  Stacy Hsueh, Beatrice Vincenzi, Akshata Murdeshwar, Marianela Ciolfi Felice · 2023 · ASSETS 2023: The 25th International ACM SIGACCESS Conference on Computers and Accessibility

  This paper applies crip technoscience as a critical, generative framework for rethinking how accessible data visualizations are designed. The authors argue that current approaches to visualization accessibility largely treat access as a technical problem to be solved by…

• Performance and Pleasure: Exploring the Perceived Usefulness and Appeal of Physical Activity Data Visualizations with Older Adults

  Dimitri Vargemidis, Kathrin Gerling, Vero Vanden Abeele, Luc Geurts · 2023 · ACM Transactions on Accessible Computing

  This mixed-methods study examines how older adults perceive and value different approaches to visualizing physical activity (PA) data from wearable activity trackers. The researchers combined semi-structured interviews (N=17) and an online survey (N=27) with 44 older adults…
