Something about this makes me think that the author of this video is a very successful (judging by the number and ferocity of the comments) troll.

While it does appear this particular device may not directly measure brain wave activity, there are similar devices being developed that work in the same way as an EEG. While I too am skeptical of their application in the gaming world, I am nonetheless excited that such devices are not only becoming affordable for home use, but are being marketed as entertainment devices.

These devices are no where near accurate enough for precision work (which includes most video game control schemes), but the idea that the devices will be available to the hacking community at affordable prices is something worth looking forward to. I am very interested to see what people come up with.

Anyone who is a fan of penny-arcade can identify this immediately: it is obviously the sinister offspring of penny-arcade's fruit fucker and a naval mine. The resemblance is just too uncanny to be anything else.
