MIT media lab: zeroN


movable by human hands or programmable by computer, the ‘zeroN’ system lets materials levitate in mid-air

with ‘zeroN‘, researcher jinha lee of the MIT media lab in collaboration with rehmi post of the MIT center for bits and atoms
have created a miniature anti-gravity-like space, where people and computers can interact with levitating materials
in a three-dimensional environment. materials can be touched and moved, left suspended in mid-air, or programmed
to follow various paths. the system also records its movement, and thus can replay human interactions.

‘zeroN’ utilizes electromagnetic forces for the levitating effect. a hall sensor tracks the location of a plastic-coated,
spherical electromagnetic every several milliseconds, relaying the data to a system that adjusts the electromagnetic
forces from above, to attract or repel the sphere precisely to maintain its position in 3D space. the unit also makes
use of infrared stereo cameras (modified from conventional webcams) and a kinect sensor to detect human presence and motion.

in addition to being used for scientific study and simulations, ‘zeroN’ can be used to program camera paths
for rendered animations, or the prototyping of movements for CGI mapping. conceptualized as a sun or lamp,
the sphere can be used to test lighting interactions and conditions on ground surfaces and architectural or scenographic
models. the surface of the floating sphere can be used for visual projections, offering interesting possibilities
for interactive planetary visualizations and artistic interventions.


demo of ‘zeroN’ and discussion with jinha lee; demos of the possible uses of the system begin at 1:12

jinha lee works in the tangible media group of the MIT media lab. hiroshi ishii was advisor to the project,
which was completed in collaboration with rehmi post of the MIT center for bits and atoms.

the system could be used for physics simulations of gravity and optics, as well as visualizations like this demo of planetary orbits


‘zeroN’ can also be used to designate the path of a ‘camera’ (the sphere), to be sent to and used in rendering applications

- please don't include your website or e-mail address in your comments for the purpose of self-promotion.
- please respect jury verdicts and do not discuss offensively on the competition results
(there is only one fist prize, and designboom usually asks renown professionals to help us to promote talent.
in addition to the awarded designs, we do feel that almost all deserve our attention, that is why we publish
the best 100-200 entries too.)

a link is allowed in comments as long as they add value in the form of information, images, humor, etc. (links to the front page of your personal blog or website are not okay). unwelcome links (to commercial products or services of others, offensive material etc. ) will be redacted. and, ... yes, spam gets banned. no, we do not post fake comments.
