For This Video Game, No Hands Necessary – NYTimes.com.

At the Figment public art show on Governors Island over the weekend, Nick Kenrick stood with his hands on his hips and his eyes squinted, concentrating feverishly on the classic video game Pong.

“I can tie it up here,” he said, as two paddles floated along opposite sides of the screen, batting a ball back and forth.

But Mr. Kenrick, 20, was not playing on the old Atari game system, nor was the game displayed on a monochromatic television screen with chunky pixels. Instead, this version of Pong was being projected onto a 6-foot-by-8-foot board of lights, which was attached to a laptop computer.

And in the most futuristic twist of all, Mr. Kenrick was moving his virtual paddle with the power of his mind.

An electroencephalogram headset measured Mr. Kenrick’s brain activity and sent that data to the computer. Through a series of digital twists and turns, the data was used to display the Pong game on the giant light board.
