It's the $199 headband that will allow you to control things using your mind, the makers say.

The Muse headband was unveiled this week at LeWeb and Stephanie Busari caught up with founder of Interaxon Ariel Garten for a demonstration of the brainwave-sensing headband.

Garten says Muse works using the same technology used in hospitals known as Electroencephalography (EEG), which records electrical activity along the scalp.

Muse is embedded with four sensors that allows you to see and track your brain's activity, in the same way a heart rate monitor gives information about your physical activity. You can also use your mind to control games and applications supplied with the headband, Garten says.
