SAN FRANCISCO — When you pull the headset over your eyes and the game begins, you are transported to a tiny room with white walls. Your task is to break out of the room, but you cannot use your hands. There is no joystick or game pad. You must use your thoughts.
You turn toward a ball on the floor, and your brain sends a command to pick it up. With another thought, you send the ball crashing into a mirror, breaking the glass and revealing a few numbers scribbled on a wall. You mentally type those numbers into a large keypad by the door. And you are out.
