Advances in brain-machine interfaces

400px-BrainGate Okay, technically your typing fingers are already brain-machine interfaces, but they’re rather clumsy ones, especially if you’re not a great typist. Wouldn’t it be easier to just think at your computer to get it to do what you want it to do? (Via ScienceDaily.)

Well, as this fascinating overview of the state of the art makes clear, it’s coming. The lede:

Neuroscientists have significantly advanced brain-machine interface (BMI) technology to the point where severely handicapped people who cannot contract even one leg or arm muscle now can independently compose and send e-mails and operate a TV in their homes. They are using only their thoughts to execute these actions.

Thought-controlled avatars for Second Life

Second Life avatars While it may obviously be some time before this technology becomes widely available to the average consumer, I’m fascinated to see a Japanese team of scientists developing a thought-control interface device that can direct the movement of a Second Life avatar. Something like that could really revolutionize the platform … although given the slightly hysterical media reports of, er, dubious pastimes in the virtual world, I’m sure people will leap to conclusions about why users would want their hands free … [Image by Pathfinder Linden]

Well, now you can tell them that the opposite is the case – an Israeli company has developed a device for killing brain tumors using weak electrical fields. Of course, your friend will just tell you how that’s what the Illuminati want you to think, but that’s half the fun. [BeyondTheBeyond]
