Benefits of technology

The invention proposes a better way to analyze a player's game when using a racket and projectile. It allows for real- or delayed-time analysis. Additionally, it improves the detection of when the projectile impacts the racket.

Problems solved by technology

Such a device seems to have a high price and weight.
Such a system is not suitable for determining impacts on the racket that are not ball impacts.
Furthermore, the number of sensors is large and the cost is high.

Embodiment Construction

[0096]FIG. 1 illustrates a method for analyzing the game of a user of a racket and of an associated projectile, wherein an impact of the projectile is detected on the racket, with which a moment of impact t0 is associated from measurements representing a shock experienced by the racket, for example by a sensor assembly comprising a gyrometer with at least one measurement axis. The sensor assembly may furthermore comprise at least one vibration sensor, and / or at least one accelerometer with at least one measurement axis. Once the moment of impact t0 is known, the data supplied by the sensors around the moment of impact t0 is analyzed to determine whether it is a stroke among the set of strokes, and to determine other parameters of the game, such as the effect, the velocity, etc.

[0097]As the example in FIG. 2 illustrates, the sensor assembly comprises an accelerometer with at least one measurement axis and a gyrometer with at least one measurement axis, the measurement axes being, for...

Abstract

A method for analyzing the game of a user of a racket (Ra) includes detecting an impact from representative measurements of a shock to the racket (Ra) provided by a sensor assembly. The sensor assembly includes at least one sensor sensitive to shocks and is connected to the racket (Ra).A moment of impact is associated with a detected impact, using the measurements transmitted by the sensor assembly.Impacts that are not related to strokes from a set of pre-determined strokes are eliminated on the basis of angular rotational velocity measurements, provided by a gyrometer (G) of the sensor assembly with at least one measurement axis and linked to the racket, taken during an interval of time around the moment of impact.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is the National Stage of International Application No. PCT / EP2013 / 058719, filed on Apr. 26, 2013, which claims the benefit of French Application No. 1254257, filed May 10, 2012, and French Application No. 1259662, filed Oct. 10, 2012. The contents of all of these applications are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]Embodiments of the invention relate to a method for analyzing the game of a user of a racket, wherein an impact, notably of an associated projectile, is detected on the racket.[0004]2. Description of the Related Art[0005]The term projectile is understood to refer to a ball, in general, in games or sports such as tennis, table tennis, squash, racquetball, or, for example, a shuttlecock for badminton.[0006]Systems are known comprising rackets equipped with sensors to provide data related to the player.[0007]United States patent publication no. 2011 / 1837...
