Notch is a 3D motion tracking system you’ll actually want to use

LAS VEGAS—Smartwatches and wearables worn on the wrist may be convenient, but they can easily miss a lot of body movements. If you're a golfer, skater, swimmer, or the like, you move with more than just your wrist when you train or compete. The 3D motion tracking startup Notch is trying to fix this by capturing most of the movement missed by traditional trackers. The company just started shipping its Notch sensor pack that has six small, triangular sensors meant to be worn on different parts of the body in order to track and visualize the movement of the user in real-time.

At the center of Notch's technology are the sensors that weigh less than 10g each. Every sensor has an accelerometer, gyroscope, and compass inside. They snap into holsters on thin straps that you wear on various body parts, and these straps are very similar to heart rate monitoring chest straps, but with more elasticity so they can stretch and fit snugly to your body. When connected to the Notch smartphone app, users can pick a movement configuration (or create their own) to follow and the sensors will capture and map their movement to the app. You can wear up to 18 Notch sensors at once, but when you wear just two sensors, you can see your movements in real-time via the app. Movements captured with three or more sensors get stored in each sensor's internal memory to be synced the next time you open the app. Notch sensors can be worn up to six hours at a time before they need to go back into the carrying case to be recharged.
