>Subjects received visual data through their taste buds and were able to correctly process it (i.e., catch a ball). If so, what about less intrusive input methods? I'm thinking of cameras, radars, sonars or entirely synthetic source of visual data with input through a pressure point grid on the user's skin [1]. This could easily have a lot of applications, from supplementing rear-view mirrors in cars with something you "see" all the time to network admins feeling which machines in their server park are being port scanned. The downside of this kind of dermal input would be the mechanical complexity of the "display" that applies pressure to your skin and the relatively low speed. A relevant question is whether if I learned to "see" with pressure applied to one patch of my skin would I be able to quickly start "seeing" with a different one? Another question is whether this scales and will you be able to use multiple inputs at the same time once you've learned one. [1] The closest thing to this that I know of is Northpaw, a haptic compass. It's 1D, though. See http://sensebridge.net/projects/northpaw/ http://sensebridge.net/projects/northpaw/.
