The ZeroN system was created by Media Lab research assistant Jinha Lee in collaboration with Dr. Rehmi Post of the MIT Center for Bits and Atoms, and the Media Lab’s Prof. Hiroshi Ishii.
Description by the designers:
ZeroN is a new physical/digital interaction element that can be levitated and moved freely by computer in a three dimensional space. Both the computer and people can move the ZeroN simultaneously. In doing so, people and computers can physically interact with one another in 3D space. Users are invited to place or move the ZeroN just as they can place any other objects on surfaces. Once levitated, ZeroN’s behavior can be digitally programmed. For example, users can place the sun above physical objects to cast digital shadows, or place a planet that will start revolving based on simulated physical conditions.
ZeroN can remember how it has been moved. Physical motions of people can be collected in this medium to preserve and play them back indefinitely. When the users move and release the ZeroN, it continues to float and starts to move along the same path. This allows a unique, tangible record of a user’s physical presence and motion which will continue to exist even after the death of the person.
