Kinect sensor wants to guess astronauts' weight, tell them to hit the space gym

How do you weigh yourself when there's no gravity keeping you down. Well, you can calculate your mass by sitting on an oscillating spring and comparing its standing frequency to your riding frequency (NASA's current method), or you could rig up a Kinect sensor to tell you when you're getting fat. Carmelo Velardo, a Eurocom computer scientist in Alphes-Maritimes, France, is developing the latter option.
