CREATE researchers shone this spring at the 2023 Web4All 2023 conference that, in part, seeks to “make the internet more accessible to the more than one billion people who struggle to interact with digital content each day due to neurodivergence, disability or other impairments.” Two CREATE-funded open source projects won accolades.
Best Technical Paper award:
Understanding and Improving Drilled-Down Information Extraction from Online Data Visualizations for Screen-Reader Users
Authors: Ather Sharif, Andrew Mingwei Zhang, CREATE faculty member Katharina Reinecke, and CREATE Associate Director Jacob O. Wobbrock
Built on prior research to develop taxonomies of information sought by screen-reader users to interact with online data visualizations, the team’s research used these taxonomies to extend the functionality of VoxLens—an open-source multi-modal system that improves the accessibility of data visualizations—by supporting drilled-down information extraction. They assessed the performance of their VoxLens enhancements through task-based user studies with 10 screen-reader and 10 non-screen-reader users. Their enhancements “closed the gap” between the two groups by enabling screen-reader users to extract information with approximately the same accuracy as non-screen-reader users, reducing interaction time by 22% in the process.
Accessibility Challenge Delegates’ Award:
UnlockedMaps: A Web-Based Map for Visualizing the Real-Time Accessibility of Urban Rail Transit Stations
Authors: Ather Sharif, Aneesha Ramesh, Qianqian Yu, Trung-Anh H. Nguyen, and Xuhai Xu
Ather Sharif’s work on another project, UnlockedMaps, was honored with the Accessibility Challenge Delegates’ Award. The paper details a web-based map that allows users to see in real time how accessible rail transit stations are in six North American cities, including Seattle, Toronto, New York and the Bay Area. UnlockedMaps shows whether stations are accessible and if they are currently experiencing elevator outages. Their work includes a public website that enables users to make informed decisions regarding their commute and an open source API that can be used by developers, disability advocates, and policy makers for a variety of purposes, including shedding light on the frequency of elevator outages and their repair times to identify the disparities between neighborhoods in a given city.
