Zap your brain into the zone: Fast track to pure focus

I was just thinking how awesome it would be to have a graph of my brain waves so I could tune them to alpha waves while coding. :)

I tested a very similar device for the company I used to work at, the UI looked identical at least. There was very little relationship between my actual mental state, and the state of the display. The device I used had an API, so I wrote my own visualizer to make sure they weren't just blurring out the data -- long story short, I was never impressed with it. Blinking or moving your head triggered a larger reaction than any thought impulse.

Maybe the tech has gotten better, but I wouldn't hold your breath for anything that costs $100.

"Blinking or moving your head triggered a larger reaction than any thought impulse."

No surprise there, the muscles of the head will have a stronger signal than the brain, if you're using electrodes outside the skull.

There might be some way of filtering those out, perhaps using additional electrodes directly on the relevant muscles. Subtract the signal on those electrodes from the signal on the other electrodes.

Also, based on the geometry of the xwave headset it looks like the electrode(s) are very rostral, so I would imagine that it picks up a lot of EOG from the eyes and EMG from the frontalis and corrugator supercilii (eyebrow muscles).

The ground, again from what I can tell from the photo, is on the earlobe. This is not a terrible place for a ground (there are no muscles there) but it's not ideal for removing EMG artifacts.

This seems really interesting. Have you played with it? What's your experience?

I have one, and it's OK -- you can notice broad differences with different activities or different mental states. The video game that comes with it is supposed to allow you to control a character, and that didn't work for me or other people who tried it at all. Also the plastic casing is really bad and broke quickly on mine. All in all neat but overpriced.

This device will measure heart-beat variability too.
