An Australian company is gearing up to release a computer headset that allows people to control video games using only the power of their minds.

Featuring 16 sensors that measure electrical impulses from the brain, the headset - which plugs into the PC's USB port - will enable games to register facial expressions, emotions and even cognitive thoughts, allowing players to perform in-game actions just by visualising them.

The headset could also detect the players' emotions - whether they're bored, angry, engaged, happy, stressed, etc - and adjust difficulty levels, in-game music and the game environment accordingly.
