APPAREL BASED DYNAMIC MOVEMENT SCORING

Abstract:

A system for dynamic movement scoring comprising an article of footwear or apparel and a processor in networked wireless communication with the article of footwear or apparel. The article includes at least one accelerometer or inertial measurement unit operative to monitor spatial motion of at least a portion of the article of footwear or apparel, and to generate a data stream indicative of the monitored spatial motion. The processor is configured to receive the data stream from the article of footwear or apparel, identify at least one motion primitive from the received data stream; and determine an accuracy metric representing a correspondence between the monitored spatial motion of the article of footwear or apparel and the ordered number of motion primitives.
