Researchers at MIT have discovered the key to gesture-based computer (a la Minority Report): a multicolored Lycra glove that costs about $1 to manufacture. The glove is covered with 20 irregularly shaped patches that use 10 different colors that are all picked up by a standard webcam. Using a “new algorithm for rapidly looking up visual data in a database” the glove can be used to “gauge hand position in three dimensions — including the flexing of individual fingers — as well as a possible application in mechanical engineering.” Love it.
