The strong magnetic field controlled by the computer along with optical tracking system and a projector are used to make the ball move around. Jinha Lee, the one who has made this project has been telling that this anti gravity ball could be used in various fashions, like by projecting our solar systems and even manipulating some controls of physical motion to digital motion.
The stability and the vertical hold of the ball is also appreciatable, since it has no disturbance as the magnetic field puts a firm hold over it.
