Emotiv is on the cutting edge of that technology with headgear that allows you to do things, such as make a toy car whiz by or help a quadriplegic mix music like a DJ using just their brain power. It works by scanning your brain for signals using the Emotiv EEG device on your head. That device then relays your signals through a brain-computer interface to detect emotions, interest and a slew of other things. Sarah Buhr demos the most recent prototype of Emotive's new wireless neuro-headset.
