Honda brings robot mental control

Thu, 2006-05-25 15:53 -- John Hawks

It seems clear that we have only one hope against superintelligent fearless killer mice: Robots that carry out our telepathic commands!

Happily, Honda Motor Co. is preparing for the day:

In a video demonstration in Tokyo, brain signals detected by a magnetic resonance imaging scanner were relayed to a robotic hand. A person in the MRI machine made a fist, spread his fingers and then made a V-sign. Several seconds later, a robotic hand mimicked the movements.

I don't know about robotic hands pre-equipped to make a victory sign...

What Honda calls a "brain-machine interface" is an improvement over past approaches, such as those that required surgery to connect wires. Other methods still had to train people in ways to send brain signals or weren't very accurate in reading the signals, Kamitani said.

This is interesting in that computers are being used to capture the signs in brains that are not consciously produced, as opposed to methods of training people to make brain wave patterns that can be externally perceived with much cheaper and lighter equipment. It presupposes a future in which methods of scanning brains become much cheaper and ubiquitous. I suppose they might if there were reasons -- and maybe a multipurpose wear-anywhere brain scanner really would sell if they had lots of uses.

Like for voting on "American Idol"...

Neandertals

For years, I've worked on their bones. Now I'm working on their genes. Read more about the science studying these ancient people.

Denisova

From a finger bone of an ancient human came the record of a completely unexpected population. My lab is working on the science of the Denisova genome.

Acceleration

The advent of agriculture caused natural selection to speed up greatly in humans. We're uncovering some of the ways that populations have rapidly changed during the last 10,000 years.

Malapa

Just outside Johannesburg, the Malapa site is producing some of the most exciting finds in human evolution. This site is the headquarters of the Malapa Soft Tissue Project.
