JavaScript visualization libraries are widely used to create online data visualizations but provide limited access their information for screen-reader users. Building on prior findings about the experiences of users with visualizations, we present VoxLens, an open-source plug-in that—with a single line code—improves accessibility using multi-modal approach. Specifically, VoxLens enables obtain holistic summary presented information, play sonified versions data, and interact in "drill-down"...
Online data visualizations are widely used to communicate information from simple statistics complex phenomena, supporting people in gaining important insights data. However, due the defining visual nature of visualizations, extracting can be difficult or impossible for screen-reader users. To assess users' challenges with online we conducted two empirical studies: (1) A qualitative study nine users, and (2) a quantitative 36 non-screen-reader Our results show that inaccessibility users...
In graduate school, people with disabilities use disability accommodations to learn, network, and do research. However, these accommodations, often scheduled ahead of time, may not work in many situations due uncertainty spontaneity the experience. Through a three-person autoethnography, we present longitudinal account our school experiences as disabilities, highlighting nuances tensions when requested did alternative coping strategies. We retrospective journals field notes reveal impact...
The usage of identity- (e.g., "disabled people") versus person-first language "people with disabilities") to refer disabled people has been an active and ongoing discussion. However, it remains unclear which semantic should be used, especially for different disability categories within the overall demographics people. To gather examine preferences people, we surveyed 519 from 23 countries. Our results show that 49% preferred identity-first whereas 33% 18% had no preference. Additionally,...
Graphs are considered as one of the most important tools to represent information, and such, they widely used across Internet in various formats visualize statistics data. However, for visually impaired individuals, who can presently rely only on ALT attribute images, receiving interpreting information displayed graphs is a highly challenging task. This paper presents novel solution this problem, called evoGraphs, which jQuery plugin that allows users create fully dynamic, customizable...
Keyboard-based emoji entry can be challenging for people with visual impairments: users have to sequentially navigate lists using screen readers find their desired emojis, which is a slow and tedious process. In this work, we explore the design benefits of speech input, popular text method among impairments. After conducting interviews understand blind or low vision (BLV) users' current input experiences, developed Voicemoji, (1) outputs relevant emojis in response voice commands, (2)...
Sonification is a commonly used technique to make online data visualizations accessible screen-reader users through auditory means. While current sonification solutions provide plausible utility (usefulness) in exploring visualizations, they are limited the quality (usability) of sonified responses. In this preliminary exploration, we investigated usability and user-friendliness visualization for users. Specifically, evaluated Pleasantness, Clarity, Confidence, Overall Score discrete...
Inaccessible online data visualizations can significantly disenfranchise screen-reader users from accessing critical information. Current accessibility measures, such as adding alternative text to visualizations, only provide a high-level overview of data, limiting exploring in depth. In this work, we build on prior research develop taxonomies information sought by interact with granularly through role-based and longitudinal studies users. Utilizing these taxonomies, extended the...
Inaccessible urban infrastructure creates and reinforces systemic exclusion of people with disabilities impacts public health, physical activity, quality life for all. To improve the design our cities to enable more equitable policies location-centric technology designs, we need new data collection techniques, standards, accessibility-infused analytic tools interactive maps focused on quality, safety, accessibility pathways, transit ecosystems, buildings. In this workshop, bring together...
Prior work has studied the interaction experiences of screen-reader users with simple online data visualizations (e.g., bar charts, line graphs, scatter plots), highlighting disenfranchisement in accessing information from these visualizations. However, interactions geospatial visualizations, commonly used by visualization creators to represent COVID-19 cases per US state), remain unexplored. In this work, we study and extraction Specifically, conducted a user 12 understand they seek...
Incorporating uncertainty in data visualizations is critical for users to interpret and reliably draw informed conclusions from the underlying data. However, visualization creators conventionally convey information regarding using visual techniques (e.g., error bars), which disenfranchises screen-reader users, who may be blind or have low vision. In this preliminary exploration, we investigated ways users. Specifically, conducted semi-structured interviews, finding that these prefer obtain...
For over six decades, Fitts's law (1954) has been utilized by researchers to quantify human pointing performance in terms of "throughput," a combined speed-accuracy measure aimed movement efficiency. Throughput measurements are commonly used evaluate techniques and devices, helping inform software hardware developments. Although extensively HCI beyond, its test-retest reliability, both throughput model fit, from one session the next, is still unexplored. Additionally, despite fact that prior...

How do sidewalks change over time? Are there geographic or socioeconomic patterns to this change? These questions are important but difficult address with current GIS tools and techniques. In demo paper, we introduce three preliminary crowd+AI (Artificial Intelligence) prototypes track changes in street intersection accessibility time—specifically, curb ramps—and report on results from a pilot usability study.
ACM SIGACCESS Conference on Computers and Accessibility (ASSETS) is considered one of the premium forums for research accessibility. Recently, Mack et al. shed light demographics, goals, methodologies, evolution accessibility over time. We extend their work by exploring frequencies trends disability categories computer science domains in publications at ASSETS (N=1,678). Our results show that varied significantly across publication years. found past 10 years, targeting Mental-Health-Related...
Geovisualizations are powerful tools for exploratory spatial analysis, enabling sighted users to discern patterns, trends, and relationships within geographic data.
