Linespace is a tactile display system for blind users. The foundation of our system is a large 140x100cm display area, on which the system creates raised tactile lines with the help of a 3D printer. The foot switch allows users to enter text and issue commands by talking to the computer. In the video you see a user using this system to find homes in Berlin
What an amazing use of 3D printing.
Linespace is a product of the Human Computer Interaction Lab at the Hasso-Plattner-Institut. Check out their site for some other interesting projects including the “Protopiper” that made the rounds recently.
