"Hitachi's already dipped its toes (or hands, as it were) into the gesture-based waters before, but it looks to have refined things quite a bit for its latest Minority Report-esque demo, which the company is showing off as part of its 100th anniversary celebration. While complete details are a bit light, the system does seem to be reasonably responsive, and appears to rely on a projection-based system and a single camera to track movements. Perhaps what's most interesting, however, is that Hitachi eventually sees systems like this being used in everything from digital signage to medical applications -- and, yes, even TVs and desktop computers (though not before mid-2011 at the earliest). Head on past the break to check it out in action."^^<http://www.w3.org/2001/XMLSchema#string>
