All a user has to do to control his/her avatar is imagine performing various movements.

The activity monitored by the headpiece is read and plotted by an electroencephalogram, which relays it to a computer running a brain wave analysis algorithm that interprets the imagined movements.

A keyboard emulator then translates the data into signals which can be used to control the movements of the user's on-screen avatar in real-time.

When the bad guy blows the s**t out of you, your brain thinks you're dead.

And guess what, you are.
