The researchers conducted a formative interview study with 15 blind and low-vision participants to understand their challenges and strategies for accessing diagrams. They found that lack of accessibility is a frequent issue, and existing solutions such as alt-text or asking sighted people for help are often insufficient or costly in terms of time, effort, and social capital.
To address this, the researchers designed TADA, a tablet-based interactive system that allows blind and low-vision users to access node-link diagrams through a range of techniques:
The researchers evaluated TADA with 25 participants and found it useful for gaining different perspectives on diagrammatic information.
