The ZeroN system was created by Jinha Lee, a Media Lab research assistant. Above its open-air anti-gravity space sits an electromagnet, that can be moved vertically and horizontally via a three-axis motor controller. To the side is a stereo infrared motion-tracking system made with two stock Sony PS3 Eyecam cameras, along with a video projector. A second projector and third camera sit beneath a horizontal translucent screen, that is located on a tabletop underneath the anti-gravity space.
As the user reaches into the space with the ZeroN ball in their hand, the motion-tracking system keeps track of where it is. It relays this information to the motor controller, which moves the electromagnet accordingly. When the user lets go, the magnet will be in such a position that its magnetic field holds the ball in place, right where the user left it. If they then reach in and reposition it, the electromagnet will move with it, to keep it hovering in its new location.
Along with simply keeping the ZeroN where it was left, however, the system can also record its movements and then play them back. This means that the ball could be guided through an aerial routine by hand, let go, and then proceed to repeat that routine on its own.
