BodyWave BodyWave is a brain wave monitor that attaches to the body much like an MP3 player. There’s no need to wear a headset. Three dry sensors on the back of the unit contact the skin and begin searching for brainwave activity. The brain wave patterns are transmitted via Bluetooth or WiFi to a computer or hand held device. Brainwave activity can control computer activities, 3D training scenarios, or live field equipment. Manufacturer's website (with videos 0:54, 0:48, 0:56) http://www.freerlogic.com/body-wave/
