Abstract

Some embodiments are directed to an analysis device for board sports, intended to be secured to a board, such as a surfboard or ski, at the interface with the user. The device includes: a force sensor designed to capture one or more forces generated by the user on the board; a position and motion sensor designed to capture the position, speed and acceleration of the board in space; and a processing unit or processor connected to the force sensor and to the position and motion sensor and designed to synchronize and process the data from the sensors.

First claim

The invention claimed is:

1. An analysis device for a board sport configured to be fixed onto a board support, including at least one of a surfboard and a ski, at an interface with a user, the device comprising:
a force sensor suitable for capturing one or more forces generated by the user on the board support;
a position and motion sensor suitable for capturing the position, the speed and the acceleration of the board support in space; and
a processor connected to the force sensor and to the position and motion sensor and suitable for synchronizing and processing the data from the sensors, wherein the processor further includes a computation unit including a predictive model making it possible to determine the motions of the board support from measured data originating from the force sensor and the position and motion sensor.

2. The device as claimed in claim 1 , further including a camera connected to the processor, the camera being positioned to capture the image of the user.

3. The device as claimed in claim 1 , wherein the force sensor, the position and motion sensor and the processor are associated with a sealed device positioned as intermediary between the force sensor and the user.

4. The device as claimed in claim 1 , wherein the position and motion sensor includes a 3-axis gyroscope, a 3-axis accelerometer and a magnetometer.

5. The device as claimed in claim 1 , further including a storage memory for the synchronized and/or processed data.

6. The device as claimed in claim 1 , further including a transmitter for transmitting the synchronized and/or processed data in real time to an analysis and display computer via a wireless link.

7. The device as claimed in claim 1 , wherein the device is formed by a coating provided with at least one fixing zone intended to be fixed to the board support.

8. The use of a device as claimed in claim 1 , configured for learning and perfecting a board sport.

9. A method for learning a board sport using a device as claimed in claim 1 , comprising:
using the device by a user to practice the board sport and record data from the sensors of the device;
processing the data and comparing the processed data with reference data; and
processing and merging the data for a conversion and a display of user assessment and progress parameters,
wherein the data processing step further includes determining the motions of the board support from measured data originating from the sensors via a predictive model.

10. The method as claimed in one of claim 9 , wherein the display of the assessment and progress parameters is produced in graphic form highlighting the difference in position of the user relative to the position of a reference user.

11. The method as claimed in claim 9 , wherein the display of the assessment and progress parameters is produced in graphic form highlighting the differences in position between different users.

12. A board support, comprising: at least one of a surfboard and a ski, including the device as claimed in claim 1 .

13. The board support as claimed in claim 12 , wherein the device is incorporated in the board support.

14. The device as claimed in claim 2 , wherein the force sensor, the position and motion sensor and the processor are associated with a sealed device positioned as intermediary between the force sensor and the user.

15. The device as claimed in claim 2 , wherein the position and motion sensor includes a 3-axis gyroscope, a 3-axis accelerometer and a magnetometer.

16. The device as claimed in claim 3 , wherein the position and motion sensor includes a 3-axis gyroscope, a 3-axis accelerometer and a magnetometer.

17. The device as claimed in claim 2 , further including a storage memory for the synchronized and/or processed data.
