Abstract

Apparatus, systems, and methods are provided for measuring and analyzing movements of a body and for communicating information related to such body movements over a network. In certain embodiments, a system gathers biometric and biomechanical data relating to positions, orientations, and movements of various body parts of a user performed during sports activities, physical rehabilitation, or military or law enforcement activities. The biometric and biomechanical data can be communicated to a local and/or remote interface, which uses digital performance assessment tools to provide a performance evaluation to the user. The performance evaluation may include a graphical representation (e.g., a video), statistical information, and/or a comparison to another user and/or instructor. In some embodiments, the biometric and biomechanical data is communicated wirelessly to one or more devices including a processor, display, and/or data storage medium for further analysis, archiving, and data mining. In some embodiments, the device includes a cellular telephone.

First claim

What is claimed is:

1. A method of evaluating a user's body movement, the method comprising:
providing a plurality of sensors for association with portions of a user's body, including providing at least a single first sensor having a first sampling rate and a single second sensor having a second sampling rate;
associating a control unit with the user, the control unit being configured to receive data from the plurality of sensors;
configuring a processor to communicate with the control unit and process information related to the movement of the sensors;
associating the single first sensor with a first portion of the user's body, the first portion being expected to move faster than a second portion of the user's body during a planned activity for which movement is to be evaluated;
associating the single second sensor with the second portion of the user's body; and
configuring the single first sensor to achieve a faster sampling rate than the single second sensor in order to allow sufficient data for evaluating the movement of the first and second body portions during the planned activity.

2. The method of claim 1 , wherein associating at least the single first sensor with a first portion of the user's body comprises associating the single first sensor with an arm or hand.

3. A method of tracking body motion of a mover, the method comprising:
providing multiple sensors, each of which comprises at least a multi-axis accelerometer for measurement of three-dimensional movement and a gyroscopic sensor for measurement of orientation;
associating a single first one of the sensors with a first body portion of a mover and associating a single second one of the sensors with a second body portion of the mover;
determining a sample rate for each of the sensors —wherein the sample rate for the single first one of the sensors associated with a faster moving body portion is higher than the sample rate for the single second one of the other sensors associated with a slower moving body portion —and causing each sensor to begin sampling at the determined sample rate;
using the multiple sensors to collect biometric data showing movement of the mover's body portions when the mover moves;
providing a first processor;
communicating the biometric data from the sensors to the first processor;
communicating the biometric data to a second processor comprising a learning center configured as a web-connected computer system;
providing for access by a user to the learning center;
displaying a three-dimensional animation of the movement of the mover's body portions resulting from the data; and
storing the biometric data in a database for comparison and analysis.

4. The method of claim 3 , wherein providing a first processor comprises providing a master control unit that accompanies the mover during the movement to be tracked.

5. The method of claim 3 , further comprising providing access to the biometric data through a user interface in real time, wherein real time comprises less than one minute after the movement has occurred.

6. The method of claim 3 with additional steps for tracking body motion of a second mover, the method comprising:
providing additional sensors for a second mover, each additional sensor comprising at least a multi-axis accelerometer for measurement of three-dimensional movement and a gyroscopic sensor for measurement of orientation;
associating one of the additional sensors with a first body portion of the second mover and associating another one of the additional sensors with a second body portion of the second mover;
using the multiple sensors to collect biometric data showing movement of the second mover's body portions when the second mover moves;
communicating the biometric data from the additional sensors to a processor;
storing the biometric data of the second mover in the database for comparison and analysis; and
allowing for display and comparison of biometric data from multiple movers.

7. The method of claim 6 , wherein allowing for display and comparison of biometric data from multiple movers comprises displaying a three-dimensional animation of the biometric data representing movement of one or more of the movers.
