When we think of full-body motion capture, we most often associate it with movie-grade equipment that demands a dedicated room, odd-looking suits and a corporate bank account to finance it all. Xsens hints that we may not have to rent a professional studio (or stand in front of a Kinect) to get complete body tracking for personal use. It's planning to show a wearable, 3D-capable tracking system at CES that uses "consumer grade" MEMS sensors to monitor joint positions and movement -- in other words, the kind of technology that might go into a phone's accelerometer, just strapped to our arms and legs. Further details are scarce, although Xsens is pressing for uses in everything from fitness to gaming. We'd like to see partners line up so that there's a product we can buy in a store. Until then, we'll have to make do with the company's skateboard-dominated teaser clip, which you can find after the break.
