A New Breed of Wearables Will Give You Data You Can Actually Use [Wired.com]
Motion capture isn’t new, of course. The Wii and Kinect first introduced the technology on a mass scale in our living rooms. But the Kinect and Wii work by using larger sensors spaced out in a room — infrared projectors, cameras, accelerometers and IR detection, all feeding back to a base unit where the heavy data processing takes place. Some of today’s wearables are capable of performing motion capture and data crunching on par with the Wii — and even bettering it in some cases — but in a form factor smaller than a credit card.
