Am I the only one who thinks this is all bullshit? How exactly does a headband "detect brainwaves" and "concentration"? If it was that easy to minaturise this shit, why are CT scanners the size of vans?
a single small sensor, like in an EKG
a CT scanner actually looks at your entire brain and maps out activity.
the single sensor just notes activity in an area and responds to it.
plus, at CT scan can work in the outer brain areas, which is some weird part that the mapping of varies from person to person.
basically, someone rigged an EKG sensor to some electronic bits.
I'm still not very convinced. Detecting brain impulses is all well and good, but normally such devices have dozens of little receivers which you stick all over the head. I find it hard to believe that one sensor in a small box on the side of your head can actually gauge your "attentiveness" and "relaxation" states, especially when relaxation itself still uses a lot of brain activity (you use as much brain power to look at a beautiful sunset as you would to complete a difficult maths puzzle).
sunset=math problem in brain power? i'd be interested to see the sources that did that research.
the device seems to be a modified neurosky
http://www.neurosky.com/
the company even has development applications and simple games that are controlled by the device.
on the topic of neural sensors, emotiv http://www.emotiv.com/ has development, games, and a far more advanced and expensive sensor.
besides, there is that nerf mindbullets project that also uses a neurosky to make a mind controlled nerf gun.
