 This is Russell from The Verge and we're looking at Notch. It's a motion tracker like Jawbone or Fitbit, but this one goes farther, tracking different parts of your body independently. The idea is that you put sensors like this on your wrist, your elbow, your torso, and then get data from all of them at once. So if you want to know how high you can karate kick, for instance, this will tell you, along with momentum and skeleton tracking info. The CEO calls it symbolic muscle memory, a way of quantifying specific motion like a cartwheel or a tennis serve. This one's just a prototype, the Kickstarter launches next month with a bare bones tracking system, but the cool stuff will come when we see what people can build on top of it. The company says they've seen interest from martial artists, dancers, skydivers, anyone who wants to track a certain motion so they can study it and recapture it later. Beyond the obvious physical uses, something like this could be used for Gollum style motion capture, physical therapy, or things we haven't even thought of yet. At the moment, what it does is just give you a lot of information about how your body is moving at any given time.
