Abstract

A physical skills training system in which motion sensor data is collected and analyzed under dynamic training conditions, for the purpose of automatically identifying the type of motion being attempted, assessing said motion, and providing real-time feedback to the user so the user may adjust their subsequent orientations and movements without interruption of normal game play. The system operates under ongoing, dynamic training sessions wherein the user may continuously move about a field of play and select from a variety of positions and motion types, in addition to stationary practice scenarios. The system provides a calibration mode, in which a user may create optimum, user-specific reference profiles, which are stored in the computer, and a measured play mode in which user movements and orientations are continuously assessed against the reference motions and feedback is provided in real-time.

Claims

1. A motion sensing and feedback system with ongoing active play orientation determination, comprising:

one or more sensors, each sensor capable of capturing user motion data including movements, orientations, and location, and of communicating sensor data to a computer for analysis; and

a computer capable of (1) storing previously captured profiles of reference motions, (2) processing incoming said sensor data from the user'"'"'s measured motion, (3) transmitting an indicator signal during active play as feedback to the user on the measured motion; and

a computer program that executes on said computer and is capable of (1) analyzing the sensor data under ongoing dynamic training conditions, wherein a user may select from a plurality of positions and motion types for each motion performance, and (2) producing a real-time feedback signal to indicate deviations of each motion performance from one or more reference motions, where said reference motions are automatically determined by the computer program.

2. The system in claim 1, wherein the computer program further comprises a mechanism to analyze captured sensor data and to produce a report with a user-specified or default set of summary and detail information on motions, accuracy, and feedback over an entire training session.

3. The system in claim 1, wherein each of the said motion sensors comprises one or more of:

a tri-axis accelerometer to measure differential acceleration of the sensor;

a tri-axis gyroscope to measure differential rotation around the sensor; and

a tri-axis magnetometer to measure a local magnetic field vector at each motion sensor.

4. The system in claim 1, wherein one or more motion sensors communicate wirelessly with the computer.

5. The system in claim 1, wherein data may be further transmitted to a remote computer for additional processing and feedback.

6. The system in claim 1, wherein the indicator signal for feedback comprises one or more of:

an audio signal, a visual signal, and a physical signal.

7. The system in claim 1, wherein the said computer and said sensors are integrated into a single unit that is attached to the user or training equipment.

8. The system in claim 1, wherein:

one or more additional sensors capture sensor data tracking user, ball, or opponent location; and

the computer program comprises a mechanism to use the said user, ball, or opponent location data to further analyze motion data and generate feedback signals to indicate deviations from said reference motions.

9. The system in claim 1, wherein the computer program further comprises a method of producing a real-time signal to announce to the player a type of motion to be taken by the user.
