I think there is something fundamental behind motivations to liberate physical matter from gravity and enable control. The motivation has existed as a shared dream amongst humans for millennia. It is an idea found in mythologies, desired by alchemists, and visualized in Science Fiction movies. I have aspired to create a space where we can experience a glimpse of this future. A space where materials are free from gravitational constraints and controllable through computing technologies. ZeroN is about liberating materials from the constraints of space and time by blending the physical and digital world.

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.

From Levitation Point to Levitation Space
To realize such interactions, we developed a magnetic control system that can levitate and actuate a permanent magnet in a pre- defined 3D volume. This is combined with an optical tracking and display system that projects images on the levitating object. Conventional levitation only enables levitating an object at one point. In ZeroN Project, users can move a levitated object to anywhere in a predefined 3D space and leave it there without dropping it since the system constantly readjusts both magnetically and mechanically. It is about turning 3D space into levitating space.

Beyond - Collapsible Input Device What would it be like to reach into the screen? Beyond is a collapsible input device for direct 3D manipulation. When pressed against a screen, Beyond collapses in the physical world and extends into the digital space of the screen, so that users have an illusion that they are inserting the tool into the virtual space. Beyond allows users to interact directly with 3D media without having to wear special glasses. One can select, draw, and sculpt in 3D virtual space.Click to see more>
