+ - ZeroN: Anti-Gravity metal ball for an interface->

udas writes "HCI (Human Computer Interface) has gone from flicking switches for binary bits, to keyboards, to mice and trackballs, even cortical implants. Now, Researcher Jinha Lee at MIT has created an intelligent metal ball that can float in mid air. It can be used to record, imitate, replay motion, as well as demonstrate pre-programmed motions, potentialy to visaulize motion in complex force fields. Maybe a future classroom will have interactive toys to teach pricnciples of dynamics, gravity, etc!"
