Emotiv

A first-generation commercial brain-computer interface (BCI) is being released by Emotiv Systems later this year. What does the future hold for BCI? By 2050, and likely sooner, you will be able to buy a BCI device that records all your dreams in their entirety.

Last night a company called Emotiv showed off its latest generation BCI (that's brain-computer interface) controller to a bunch of nerds from the Game Developer Conference -- including our sister site Kotaku's brave and fearless Brian Crecente. Basically, you stick this helmet on your head and control what's on screen via brain-generated electricity that's picked up by EEG sensors.
