IC2D

A drawing application developed at UC Berkeley that enables blind and visually impaired users to create, explore, and label graphical images using a keyboard-operated grid-based auditory interface. IC2D uses a recursive 3x3 grid mapped to the telephone numpad for spatial navigation, with speech feedback providing information about cursor position, cell contents, and object labels. The system includes shape palettes, color palettes, and a labeling mode for assigning meaningful text descriptions to drawn objects. Research demonstrated that blind users could create meaningful drawings with IC2D, challenging the assumption that graphical content creation is inherently inaccessible to people without vision.
