CES 2014 - Not to be confused with the guy who created Minecraft, but Notch is a new motion tracker that takes motion tracking to an entire new level.
Every single sensor in Notch collects accelerometer data, with 10 sensors pushing back the data to a user's smartphone at all times. The data collected is enough to allow skeletal tracking, as well as a much more detailed analysis on how your body is moving. Walking isn't a problem, but for physical movements like swinging a tennis racket, or a fly-kick, it will offer much more data into how the mechanics of the body are at that particular time.
Stepan Boltalin, CEO and co-founder calls it "symbolic muscle memory", which is a way of quantifying the motion of the body in a way that most professional athletes only know by physical feel. Boltalin explains: "Martial artists want to know the height of the kick, the amplitude, all of that."
