Honda Robot Controlled By Brain Waves 137
Dotnaught writes "Honda researchers to have developed a way to control robots using human brain waves. Using brain signals read from a person in a magnetic resonance imaging scanner, a robotic hand mirrored the movement of the human controller, spreading its fingers and making a 'V' sign."

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. (emphasis mine)
Afterward, a reporter who strayed too far from the crowd was warned by security not to look behind the curtain.

Actually, even if the recordation of the brainwaves controlling the motion was instantaneous (which is, apparently, is not - I'm a rocket scientist, not a brain surgeon) I would anticipate a good deal of postprocessing to get the motion reformatted from MRI raw data to motor controls. Actually, I think several seconds is pretty damned good.
Of course, if the sister post here is true (1-5 seconds of delay for O2 variation sensing), we won't see this for any sort of useful controls in rea

universality? (Score:5, Interesting)
While I'm sure that bloodflow signatures for physical movements are similar between individuals, is there too much variability to prevent false recognition of a 'signal'?
Any neurobiologists out there care to help out?
Re:universality? (Score:5, Interesting)
At this point, it is surprising that they can even do it for an individual (discerning among these three quite similar hand movements). I am kind of skeptical myself. There is a lot of variability in fMRI signal even within an individual. I would guess the system is trained on a specific individual.
Between individuals you have additional sources of variability; for example, the foldings of the cortex are quite different from person to person. I personally have a very unusual precentral gyrus on the left side. Activity maps are typically aligned to anatomical maps so finding correspondences between individuals has to deal with the challenges of anatomical variability.
For gross things, it can be quite obvious what the person is doing. I can tell by looking at the activations in your brain if you are looking at something versus hearing something. But looking at a duck versus looking at a cow? Much harder. Making a V-sign versus making a fist? I've never seen a paper where someone reported being able to do this. It is theoretically possible, but difficult with a blurry MRI signal that aggregates over populations of neurons. You can certainly do it if you implant electrodes into the brain. Recordings from monkey premotor cortex, for example, find neurons that fire when specific movements are made.
