A 25-year-old quadriplegic sits in a wheelchair with wires coming out of a bottle-cap-size connector stuck in his skull.
The wires run from 100 tiny sensors implanted in his brain and out to a computer. Using just his thoughts, this former high school football player is playing the computer game Pong. [...]
Further out, some experts believe, the technology could be built into a helmet or other device that could read neural signals from outside the skull, non-invasively. [...] DARPA envisions a day when a fighter pilot, for instance, might operate some controls just by thinking.
I want one of those helmets!
Say, I wonder if they could ever come up with something which works in the opposite direction? That is, transferring information from computers into the human brain. Instant learning, Matrix style. That would be cool. Probably not very realistic, but fun to imagine, at least.
