This project demonstrated the feasibility of tactile vision substitution on the tongue. Experimental results are published.
This project developed a first prototype tactile vision system. A small hand- or head-controlled camera records the visual image, which is presented to the user's tongue. (Graphic variant of: Al Granberg, New York Times)
