It turned out he was using an experimental hearing aid that wired into the audio-processing region of his brain. That was amazing to me! I couldn't belive a machine was interfacing with his brain.
If you were impressed by that, take a look at
this.
This device interfaces with the visual cortex to give its wearer partial
vision. This is an old article and I'm afraid I don't have anything more up to date.
However I saw a show a little while back which had something about this (a different person I think but the same concept). Don't quote me on this but I seem to recall them saying that the interface actually gives the wearer good enough artificial vision to drive a car! I remember them actually showing him driving too so it would seem that the technology has advanced considerably since its inception.
If anybody has anything more recent on this technology, I'd be very interested in seeing it.
