System and method for gathering and analyzing objective motion data
The systems and methods described herein attempt to provide data capture and analysis in a non-intrusive fashion. The captured data can be analyzed for qualitative conclusions regarding an object's actions. For example, a system for analyzing activity of an athlete to permit qualitative assessments of that activity comprises a first processor to receive activity-related data from sensors on the athlete. A first database stores the activity-related data. A second database contains pre-identified motion rules. A second processor compares the received activity-related data to the pre-identified motion rules, wherein the second processor identifies a pre-identified motion from the pre-identified motion rules that corresponds to the received activity-related data. A memory stores the identified pre-selected motion.
1. A computer-implemented method for analyzing activity of a boxer to permit assessments of that activity using a processor, the method comprising:
receiving, by the processor, a stream of continuous activity-related data transmitted from a dual-axis accelerometer on the boxer, wherein the activity-related data includes acceleration data along each of the two axes representing a motion of the boxer;
identifying, by the processor, a punch event within the stream of continuous activity-related data;
analyzing, by the processor, the received activity-related data along both axes to determine whether the motion of the boxer represented by the activity-related data along both axes exceeds a threshold value;
when the received activity-related data exceeds the threshold value, identifying, by the processor, the activity-related data as the punch event;
storing, by the processor, the activity-related data of the punch event in a database;
determining, by the processor, a time of impact of the punch event;
extracting, by the processor, activity-related data before the punch event, including activity-related data below the threshold value;
determining, by the processor, a starting time of the punch event;
calculating, by the processor, a speed of the punch event based upon an integral of the acceleration data from the starting time of the punch event to the time of impact for the punch event;
generating, by the processor, a motion profile of the punch event;
calculating, by the processor, a force of the punch event based upon the acceleration data and the motion profile of the punch event; and
displaying the calculated speed and force of the punch event.
