Enabling Tabular Data Exploration for Blind and Low-Vision Users

In a data-driven society, being able to examine data on one's own terms is crucial for various aspects of well-being. However, current data exploration paradigms, such as Exploratory Data Analysis (EDA), heavily rely on visualizations to unveil patterns and insights. This visual-centric approach poses significant chal…

Erie: A Declarative Grammar for Data Sonification

Data sonification—mapping data variables to auditory variables, such as pitch or volume—is used for data accessibility, scientific exploration, and data-driven art (e.g., museum exhibitions) among others. While a substantial amount of research has been made on effective and intuitive sonification design, software supp…

How Do Low-Vision Individuals Experience Information Visualization?

In recent years, there has been a growing interest in enhancing the accessibility of visualizations for people with visual impairments. While much of the research has focused on improving accessibility for screen reader users, the specific needs of people with remaining vision (i.e., low-vision individuals) have been…

Making Data-Driven Articles more Accessible: An Active Preference Learning Approach to Data Fact Personalization

Data-driven news articles are widely used to communicate societal phenomena with concrete evidence. These articles are often accompanied by a visualization, helping readers to contextualize content. However, blind and low vision (BLV) individuals have limited access to visualizations, hindering a deep understanding of…

"Explain What a Treemap is": Exploratory Investigation of Strategies for Explaining Unfamiliar Chart to the Blind and Low Vision Users

Visualization designers increasingly use diverse types of visualizations, but assistive technologies and education for blind and low vision people often focus on elementary chart types. We explore textual explanation as a more generalizable solution. We define three dimensions of explanation strategies based on educat…

VisLab: Enabling Visualization Designers to Gather Empirically Informed Design Feedback

When creating a visualization, designers face various conflicting design choices. They typically rely on their hunches to deal with intricate trade-offs or resort to feedback from their colleagues. On the other hand, researchers have long used empirical methods to derive useful quantitative insights into visualization…

Exploring Chart Question Answering for Blind and Low Vision Users

Data visualizations can be complex or involve numerous data points, making them impractical to navigate using screen readers alone. Question answering (QA) systems have the potential to support visualization interpretation and exploration without overwhelming blind and low vision (BLV) users. To investigate if and how…

Visualization Accessibility in the Wild: Challenges Faced by Visualization Designers

Data visualizations are now widely used across many disciplines. However, many of them are not easily accessible for visually impaired people. In this work, we use three-staged mixed methods to understand the current practice of accessible visualization design for visually impaired people. We analyzed 95 visualization…

What makes web data tables accessible? Insights and a tool for rendering accessible tables for people with visual impairments

The data table is a basic but versatile representation to communicate data. From government reports to bank statements, tables effectively carry essential data-driven information by visually organizing data using rows, columns, and other arrangements (e.g., merged cells). However, many tables online neglect the access…

Putting scientific results in perspective: Improving the communication of standardized effect sizes

How do people form impressions of effect size when reading scientific results? We present a series of studies on how people perceive treatment effectiveness when scientific results are summarized in various ways. We first show that a prevalent form of summarizing results---presenting mean differences between conditi…
