System and method for physical activity performance analysis

1. A method for providing feedback to a skier, the method comprising:

receiving, by a feedback computer, sensor data from a plurality of sensors located in a ski boot of the skier, the sensor data representing a movement of the skier during a ski run;

receiving, by the feedback computer, video data representing a video recording of the skier during the ski run;

after the ski run, synchronizing, by the feedback computer, the sensor data and the video data; and

simultaneously displaying, on a display screen in electrical communication with the feedback computer, the video recording and the sensor data.

2. The method of claim 1 , wherein the sensor data is displayed alongside the video recording.

3. The method of claim 1 , wherein the sensor data and the video data are synchronized using time stamps.

4. The method of claim 1 , wherein the sensor data and the video data are synchronized using wireless signals transmitted between the feedback computer and a data collection computer, the data collection computer in electrical communication with the sensors.

5. The method of claim 1 , wherein the sensor data and the video data are synchronized using an internet clock or a global positioning system.

6. The method of claim 1 , wherein the sensor data includes processed data that indicates a performance of the skier during the ski run.

7. The method of claim 6 , wherein the processed data includes:

a pressure applied to at least one force sensor by a foot of the skier,

a position of the skier, and

an orientation of the skier.

8. The method of claim 7 , wherein the processed data includes a comparison of the pressure, the position, and the orientation to a best practice threshold.

9. The method of claim 6 , wherein:

the ski run includes a plurality of ski turns, and

the processed data includes, for each ski turn:

a detection of a ski turn using a peak condition, and

a performance metric relating to the ski turn.

10. The method of claim 1 , further comprising:

collecting, with a data collection computer in electrical communication with the sensors, the sensor data; and

transferring the sensor data from the data collection computer to the feedback computer.

11. A system for providing feedback to a skier, the system comprising:

a display screen;

a processor in electrical communication with the display screen; and

a computer-readable storage medium have instructions stored thereon which, when executed by the processor, cause the processor to:

receive sensor data from a plurality of sensors located in a ski boot of the skier, the sensor data representing a movement of the skier during a ski run;

receive video data representing a video recording of the skier during the ski run;

after the ski run, synchronize the sensor data and the video data; and

simultaneously display, on the display screen, the video recording and the sensor data.

12. The system of claim 11 , wherein the instructions further cause the processor to display the sensor data alongside the video recording.

13. The system of claim 11 , wherein the instructions further cause the processor to synchronize the sensor data and the video data using time stamps.

14. The system of claim 11 , wherein the instructions further cause the processor to synchronize the sensor data and the video data using wireless signals transmitted between the system and a data collection computer, the data collection computer in electrical communication with the sensors.

15. The system of claim 11 , wherein the instructions further cause the processor to synchronize the sensor data and the video data using an internet clock or a global positioning system.

16. A method for providing feedback to a skier, the method comprising:

receiving, by a first computer, sensor data from a plurality of sensors located between a foot of the skier and a sole of a ski boot worn by the skier, the sensor data representing a movement of the skier during a ski run;

processing the sensor data with the first computer to evaluate a performance of the skier to yield processed data;

transmitting, after the ski run, the processed data to a second computer, the second computer storing video data representing a video recording of the skier during the ski run;

synchronizing, by the second computer, the processed data and the video data; and

simultaneously displaying, on a display screen in electrical communication with the second computer, the video recording and the processed data.

17. The method of claim 16 , wherein:

the ski run includes a plurality of ski turns, and

for each ski turn, processing the sensor data comprises:

detecting a ski turn using a peak condition; and

determining a performance metric relating to the ski turn.

18. The method of claim 17 , further comprising transmitting the processed data from the first computer to a feedback device, wherein the feedback device provides feedback to the skier regarding the performance of the skier for the ski turns, wherein for each ski turn the performance metric is transmitted to the feedback device once the skier completes the ski turn.

19. The method of claim 16 , wherein:

the ski run includes a plurality of ski turns, and

for each ski turn, processing the sensor data comprises:

detecting a ski turn using a peak condition; and

determining a transition point relating to the ski turn.

20. The method of claim 19 , further comprising transmitting the processed data from the first computer to a feedback device, wherein the feedback device provides feedback to the skier regarding the performance of the skier for the ski turns, wherein for each ski turn the transition point is transmitted to the feedback device once the skier completes the ski turn.
