Three-dimensional tactile display for the blind

 pin servos and camera array

so this is like a 2D refreshable tactile graphics display with servo pins based on a refreshable braille display, but that respond incrementally. The display would surround a body part, and respond to an array of cameras like the motion ping pong ball thing. So the user could navigate a 3D space based on tactile reponse - so some areas in 3D space would press in alot and some areas would not press in at all, so 3D pain space, maybe.

       interesting, but if only for body parts why torture the blind with a false thing. Among consenting adults the real thing is far more... educational.   

       If you wanted to use this to teach shapes to children, shore, go for it.

       Redundant. Blind people are already three dimensional, and many of them are tactile.
