MIT's Tactile Vega-Lite: Making Charts Accessible to the Visually Impaired
2025-04-09
Researchers at MIT's CSAIL have developed Tactile Vega-Lite, a program that transforms data from sources like Excel spreadsheets into both standard visual charts and tactile charts. This tool streamlines the design process for tactile charts, incorporating design standards to help educators and designers quickly create accessible charts for the visually impaired. Users can easily understand information presented in various graphics, such as bar charts comparing minimum wages or line graphs tracking GDPs. Future improvements include a refined user interface and machine-specific customizations for enhanced usability and accuracy.
