Systems, devices and methods relating to motion data

Systems for studying motion are provided. A computing device [10] has a processor [20], an accelerometer [11], a gyroscope [12], a magnetometer [13] and storage/computer readable media [30] in communication with one another. The computing device [10] can sense, classify, qualify and/or quantify real-time motion data of a moving target against classified initial motion data in a motion library [32]. Motion data is processed as particularized units of motion. The computing device [10] may use machine learning algorithms for "training" and "learning." The computing device [10] can be used in many industries, including the fitness industry, where computing device [10] can be used with wearable technology.
