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.

Abstract: Some embodiments are directed to a real-time teaching aid device for a board sport, such as surfing, intended for a person engaging in such a sport. The teaching aid device includes a set of sensors capable of measuring the position, the speeds, and the accelerations of a surf board in a Cartesian coordinate system associated with the board; the set of sensors being connected to a measured data processing unit for determining a deterministic dynamic behavior model of the surf board; at least one signal for providing, in real-time, information relating to the deterministic dynamic behavior model of the board to the person engaging in such a sport and/or to a third party. The invention also relates to a surf board having such a device.
