BodyWave uses specially designed sensors that monitor the brain’s physiologic signal through the body to interpret your thoughts and allow you to control apps on computers and smartphones. It can also be used with computer simulations to “teach stress control, increase attention, and facilitate peak mental performance.” While I didn’t get a chance to try it myself, the guy who got to the booth just before I did learned how to drive a virtual forklift on the computer monitor in front of him within about a minute using only his thoughts and a stationary non-turning steering wheel with the company’s physiological sensors embedded on the wheel. The device “read” his thoughts – as long as he concentrated on it. When the presenter distracted the tester by tapping him on the arm, the forklift stopped moving. There was a slight ¼ second lag in time between the brain’s thoughts and the movement of the forklift on the screen, so you’re not going to be using this device for playing computer games at the moment.
