Abstract

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.

Claims

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; and

displaying the calculated speed of the punch event.

2. A computer program product comprising:

a non-transitory computer usable medium having computer readable program code embodied therein for analyzing hand activity of a boxer having an accelerometer disposed on a hand of the boxer, the computer readable program code in the computer program product comprising;

computer-readable program code for receiving 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;

computer-readable program code for identifying a punch event within the stream of continuous activity-related data;

computer-readable program code for analyzing 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;

computer-readable program code for when the received activity-related data exceeds the threshold value, identifying the activity-related data as the punch event;

computer-readable program code for storing the activity-related data of the punch event in a database;

computer-readable program code for determining a time of impact of the punch event;

computer-readable program code for extracting activity-related data before the punch event, including activity-related data below the threshold value;

computer-readable program code for determining a starting time of the punch event;

computer-readable program code for calculating 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;

computer-readable program code for generating a motion profile of the punch event; and

computer-readable program code for displaying the calculated speed of the punch event.

3. A computer-implemented method comprising:

receiving, by a computer from an accelerometer, a stream of continuous activity-related data transmitted from the accelerometer on a boxer, wherein the activity-related data includes acceleration data representing the motion of the boxer;

calculating, by the computer, 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 of the punch event;

calculating, by the processor, a force of the punch event based upon the acceleration data of the punch event; and

displaying, by the computer, the type of punch, the speed and the force of the punch event.
