Here is a 3D printed display that makes it easier for visually impaired people to explore maps and other visual information easily. Linespace has the head of a 3D printer attached to a drafting table. It is controlled using speech and gestures, producing raised shapes that can be explored using fingertips.
Linespace enables blind users to make sense of visual information. It was designed at the Hasso Plattner Institute in Potsdam, Germany.
