Race to enter the third dimension

摘要

Microsoft is not alone in trying to add depth to the way we interact with computers. In November, Sony and Swiss firm Atracsys launched a system called tCU that uses stereo cameras to track a person's movements in 30. "We cannot at present detect 'finger signs' but we can detect the raw position of your arms or legs," says Gaetan Marti, CEO of Atracsys. ICU will be used initially in interactive advertising displays, rather than the more demanding home entertainment market.
