Can a motion sensor for Microsoft's Xbox videogame console identify an infiltrating North Korean soldier?

According to a South Korean engineer it can, and it may already be in use in the heavily fortified Demilitarized Zone along the inter-Korean border.

Named Kinect, the technology developed by Microsoft and Intel enables users to operate software for Microsoft's main game console Xbox via body movement.

Ko Jae-kwan, the engineer, has modified the technology for military use as a motion detector. He says the device marks a significant improvement on conventional security sensors, which may sound a false alarm because of falling leaves or roaming animals.

A spokesman for Microsoft's Xbox division confirmed Kinect was modified by Mr. Ko for military use, adding that the technology had sufficient accuracy for non-videogame applications.
