Abstract

I.A. device designed for the learning of tennis, using R.A. glasses, worn by the players, putting at the disposal of said players, the sensitive information in R.A., developed by algorithms residing in a smartphone

Description

The present invention relates to teaching materials for teaching and learning tennis and more particularly tactics, strategy, placement to obtain the best for a victory over the opponent (s).

To date, these things are taught mainly by monitors but also by videos.

The present invention proposes to use advances in imaging technologies, localization, algorithmics, artificial intelligence and other science of digital data exploitation.

To obtain this result, the available materials range from video cameras to lidars, and other localization circuits (GPS, GALILEO, ...), accelerometer, gyroscope, encapsulated in powerful and fast integrated circuits.

To all this, we must add the advent of added reality, virtual and mixed reality, and its exploitation by artificial intelligence.

The teaching of tennis strategies and placement involves the instant determination of the position of the players, the characteristics of their instantaneous movement, the trajectory of the ball.

Of these elements, placement strategies, returning the ball along a determined trajectory are multiple and the aim of this invention is to communicate in real time and to propose "to the player" one of these strategies.

Also, the invention has three main parts:

- the location of all the elements of the game,

- developing and communicating to the player in real time the strategy using algorithms operated by artificial intelligence from data developed by the “algorithm-LA” set, physical data and known conventional strategies or news, optical and / or phonic means translating for the player by signals indicating his placement and the choice of the trajectory of the ball.

By way of nonlimiting example, FIG. 1 shows the different parts of the invention:

- a lidar system (1) captures the entire court (2) and the position of the players (3 and 4), the trajectory of the ball (5) and transmits all the data by bluetooth (for example) to a module ( 6) developing algorithms and artificial intelligence capable of developing a strategy, as well as the commands of a device (7) generating light beams on the court (2) indicating by their visible impact (8) on the court ( 2) to the player (3) the placement and the trajectory which he must give to the ball.

- In another non-limiting embodiment, glasses connected to augmented reality (MAGIC LEAP, VUZIX for example) film all of the players through their cameras.

The glasses are connected to a smartphone (bluetooth). The latter can be worn by the player or placed on a bench along the court.

It also contains image processing data which provides players' position on the court and the ball's trajectory in real time, the circuits hosting the algorithms helped by FIA to develop the strategy.

The smartphone then emits to the glasses the result of the work of the algorithm, namely the placement and the trajectory of the recommended ball, data transformed visually on the screen of the glasses into reality augmented by light points for example.

The use of ARA glasses is not limiting. The data from the algorithm can be used on virtual reality and / or mixed reality glasses. The principle remains the same: provide the player with real-time indications of his best placement and the best trajectory to give the ball.

The operation of the algorithm in real time supposes an initialization synchronized with the preparation of the player to return the ball and therefore the instant taken into account when the ball leaves the opponent.

This initial instant can be generated by the data from an accelerometer worn by the players and / or by the sound of the impact of the ball on the racket captured by a microphone initializing in the algorithm the action to be taken to return the ball. .

But all other video signals (lidar, cameras) can also be used for this initialization function.

In all devices, it is desirable to generate two light signals simultaneously for the attention of the ball returner in the form of two spots for example, one for placement, the other for the trajectory; the signals being able to be phonic in an earpiece, the device (7) being able either to generate spots on the court or zones of different colors.

Similarly, we can provide the module (6) hosting the algorithm with information such as “attack” or “defense”, the type of ball, the type of surface, a comparison function between the proposed trajectory and the actual trajectory for the if necessary generate an audible signal for example of success or error.

All the luminous information can be translated on the court by luminous arrows of different colors.
