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.-- JesusHChrist, Sep 11 2009 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.-- dentworth, Sep 11 2009 Redundant. Blind people are already three dimensional, and many of them are tactile.-- MaxwellBuchanan, Sep 11 2009 well when you put it like thatMB, I had to reread this. badly explained I think.-- dentworth, Sep 11 2009 random, halfbakery
