Tangram Workstation

A LibreOffice extension for creating tactile graphics collaboratively. Tangram enables sighted users to design graphics while providing real-time tactile feedback to blind reviewers through a connected pin-matrix display. The tool includes a palette of validated tactile fill patterns that maintain consistency across different production media (print, embossed, and pin-matrix displays), allowing creators and reviewers to work together during the design process rather than after production.
