This "sense making" platform for the blind uses 3D printing technology to help the visually impaired better understand things using their other senses. From the Hasso-Plattner Institute in Germany, Linespace is a 3D printed display that produces maps and graphs for blind people.
The tactile system prints information onto a screen for those with vision problems to interpret. Linespace addresses the problem many visually impaired people have with accessing maps and other complex graphic material. This could include touchable spreadsheets and other data visualizations blind and partially seeing people would not find accessible. This platform for the blind uses raised lines rather than braille to present the information all at once, thus enabling the display to show more complicated shapes.
