ZeroN slips surly bonds, re-runs your 3D gestures in mid-air
Playback of 3D motion capture with a computer is nothing new, but how about with a solid levitating object? MIT's Media Lab has developed ZeroN, a large magnet and 3D actuator, which can fly an "interaction element" (aka ball bearing) and control its position in space. You can also bump it to and fro yourself, with everything scanned and recorded, and then have real-life, gravity-defying playback showing planetary motion or virtual cameras, for example. It might be impractical right now as a Minority Report-type object-based input device, but check the video after the break to see its awesome potential for 3D visualization.
MIT's EMF detector bracelet takes all the fun out of radiation poisoning
We've seen our fair share of EMF detectors and other tin foil hat apparel, but no endeavor is complete without the MIT stamp of approval. Cati Vaucelle's EMF sensor bracelet is designed to pick up on any potentially harmful electromagnetic fields, allowing you to dance around the veritable minefield of computers and cell phones in your workplace, unscathed by the -- maybe, maybe not -- lethal effects of radiation being emitted. Nevermind about looking like a freak -- better safe than sorry, right? The bracelet, sensitive up to 14-inches, features an integrated LED that's illuminated whenever an EMF field over 50kHz is detected. If you'd like to see this prototype in action, a video will be presented today at Ubicomp in Seoul, or save your air miles and see it here after the break.[Via Make]
