From: Blind people can actively manipulate virtual objects with a novel tactile device
(Up) Grids, made with carton and sandpaper stripes, created to represent exactly the matrix dimensions of the virtual environment in all three Resolutions. The limits of exploration and manipulation are realized with carton borders. (Down) The same grids with also the real representations of movable and fixed objects changing in dimensions according to Resolution. From the left to the right, there are the resolutions 2 \(\times\) 2, 2 \(\times\) 3 and 3 \(\times\) 3. The represented setup has been built by specialized rehabilitation practitioners at Fondazione Istituto Chiossone, Genoa.
