"It seems like everyone is cooking up their own touch-free gesture-based control technology, just like every blogger is destined to refer to it as \"Minority Report-like\" or \"Minority Report-esque,\" or \"Tom Cruise-tastic!\" Fraunhofer's FIT, the newest such project, has recently appeared on the YouTubes, where we must say it looks pretty darn good. Not only does it not require special gloves or markers, this thing also works in real time and can support multiple users (and multiple fingers). The researchers hope to use this for working with complex simulation data and in education, although there are some kinks to be worked out: currently elements like the reflections caused by wristwatches and the orientation of the palm confuses the system. That said, the demo is pretty rad! See for yourself after the break."^^<http://www.w3.org/2001/XMLSchema#string>
