Mind control headsets for video gaming
Emotiv, a San Francisco-based company, have released a headset which allows gamers to control video games from their brain waves alone.* This is done in a completely non-intrusive manner: no crude implants or direct physical contact are required. Sensors on the headset can detect the appropriate neurochemical patterns in the wearer's head, and these are converted into actions on screen. The implications of this technology are staggering - future mainstream versions could radically alter how we interact with computers, the Internet, and each other.
This one actually developed?
How does it determine brain activity exactly? Infrared/Near IR laser? High Density EEG?
How far a distance can this be done from?
