Meet the Backtrack: a smart wearable device capable of tracking your movement. It is designed for folks who are trying to bounce back from an injury. The sensor sees you as a shape and helps you track and visualize your movement.
The device knows how you move through the space and helps you visualize the range and distribution of your back movement in 360 degrees. It also visualizes the complexity and fluidity of your movement to help you see whether you are making any progress. This fascinating project is on Kickstarter at this time.
