The above picture shows Emotiv Systems new development, a $300 headset with 14 sensors about it’s body to utilize neurological signals to affect gameplay during video games, so in essence, if you smiled, Mario could smile too while speeding around in his go-cart!
Snazzy, no? You can read a full length article on the headset in “Scientific American” here:
