The rehab process can be quite frustrating for athletes and people who live an active lifestyle. Your movement does affect your recovery though. Backtrack is an innovative device that can be attached to your back to analyze your movement and visualize your recovery. By tapping on it, you let the device know when you are feeling pain.
This wearable will rely on IMU sensors to sense relative position and shape. The data is sent to your phone over Bluetooth. The companion app lets you visualize your movement, its complexity, and fluidity. You can find out more about this project on Kickstarter.
