With a chip implanted in his brain, a 23-year-old quadriplegic moves his fingers and hand.
Thanks to a computer chip, algorithms, and nearly 10 years of research, a 23-year-old quadriplegic moved his fingers and hand with the power of his own thoughts.
"I never dreamed I would ever be able to do that again," said Ian Burkhart, of Dublin, Ohio. Burkhart, who was injured in a 2010 diving accident, is the first patient to use Neurobridge, an electronic neural bypass system developed at the Ohio State University Wexner Medical Center.
The system, which is aimed at spinal cord injuries, is designed to reconnect the brain directly to muscles, allowing voluntary and functional control of a paralyzed limb.
The technology may one day give self-propelled movement back to patients affected by brain and spinal cord injuries.

When I was a teen, the foundation series of books made me wqant to become a roboticist. Now this is different, but stoking those old embers into a new fire. Instead of making a robot to feed the man I might be able to fix the man so he can feed himself. This is very very cool!

I'm waiting for the day we can get a bluetooth version of this tech, so that I can type at blinding speed without moving my fingers.

Quadriparesis [wikipedia.org] would be more correct term because Ian has only motor loss, no loss of sensation. You can see at the end of video [youtube.com] that a man grabs his hand to congratulate him.
Also "The university reported that Burkhart's thoughts are translated into movement within a tenth of a second." It's 100 ms only for the decoding, that is 10 fps. I hope they can improve this lag.

A 100ms lag isn't great, but as long as you can see what you're doing, it's probably not going to be much of a problem in real life. Someone who was completely paralyzed probably won't mind the fact that they can't play reaction games or do other things that require high-speed movements, just being able to do simple things like pouring a drink and drinking it without any help is a huge improvement.
I think a little lag on the actuator isn't quite a bad as lag on the sensors (eyes), as an experiment with an Oculus Rift recently showed. The brain is probably better at compensating for the delay of the actuator, when the feedback into the brain is free of delays, compared to the other way around.
The article and video only show a one-way interface; it's probably even harder to relay information in the other direction, to make the user feel pressure, temperature, etc., which we normally use as feedback when gripping things. If he can just move his hands, he wouldn't know how tightly he is gripping something.
Of course, this can be at least partially resolved by using specially designed objects, like a cup with a large rim or finger-sized indentations, so that the shape prevents the cup from slipping out of his fingers, instead of just the friction generated by the gripping force. In the same way, other objects could be designed that can be more easily held without the sensory feedback from the hands.

Wait, what? I didn't get this the first time I read your reply.
The man shaking his hand doesn't imply his sensory nerves still work. I don't know a whole lot about this, but is it possible he can still feel everything, but can't control his muscles? The article and video seemed to imply he has a spinal cord injury.

The journalist is a complete idiot, aside from the fact that there isn't anything about the actual interface to the brain (a "microchip" is not an interface), the article apparently wasn't long enough, so he decided to include some completely irrelevant bullshit about a hypothetical military exoskeleton and an outdated quote from a totally unrelated researcher who said "in 10 to 15 years" six years ago, which the journalist translated into "either in 2017 or in 2022".
I wonder how they actually did interface the brain; did they use electrodes to make a direct electrical connection, which has been done before with insects and small animals, but from what I've read usually causes various problems after a few weeks or so, or did they use something like a capacitive coupling, which doesn't require direct metal (or other conductor) contact to the organic material? Does he really have a huge connector in his head, or is that some kind of magnetic pickup, with inductive data and power coupling to the device in his head?

"I wonder how they actually did interface the brain"
You're talking about pinouts and EE stuff. Thats interesting. The API is also interesting. Is it flexible enough to support, with some training, perhaps 4 arms instead of the stock 2? Expansions would be a cool area to research. Especially for .mil. Don't give them virtual legs or something dumb like that, give them a new limb called "tank" that only exists as a conceptual object.
I imagine training new senses and limbs that never existed before would be complicated, but cool.

The connector going into the dude's nugget is GINORMOUS!!
I hope they can scale that down eventually. Maybe put some cool stickers on it or something. A little less Borg-ish...
