This racket can be used with a variety of balls, and can also be run via tablet, mobile It can also be used on smart TVs. It also has a high-performance, rechargeable battery that communicates via Bluetooth to a mobile phone or tablet, and has its memory.

The present invention is an intelligent racket in the context of the Internet of Things (IoT), and although at first glance it is very similar to ordinary rackets and its weight does not differ from ordinary rackets. This racket has several sensors and has intelligent functions that give it unique capabilities and distinguish this racket from other common tennis rackets. To make these rackets smarter, an application has been designed that registers smart racket information and in addition has other advantages that are mentioned below. using this smart racket, the user can get the difference between the size of his arm muscles, etc. With the desired person, and in this system, the level of play of two competitors can be checked based on some parameters, including simulation of muscle size. In this plan, the influencing factors in the individual game (in addition to techniques and game level) are estimated. In this way, the player can reach the most desired level in every aspect with proper bodybuilding exercises.

Exercise is done for different purposes among people. This can be used as an art to increase fitness and flexibility, or for competition, competition. Due to the Olympic nature of disciplines such as tennis and table tennis, the importance of success on the big courts is very high for governments, so there are very high costs for these disciplines.

In the sport of tennis, the correct and timely execution of movements is very important. Although the nature of most disciplines is based on strength and speed activities, having capabilities, such as high maximum power, good reaction speed, high muscle strength, flexibility, balance, agility is very effective in player success. Tennis is a racket sport that can be played individually against a single opponent (singles) or between two teams of two players each (doubles). Each player uses a tennis racket that is strung with a cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court The object of the game is to maneuver the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball will not gain a point, while the opposite player will. when preparing for competitions or training, the athlete needs a coach or training assistant, and sometimes none of them are present or the coach does not have to determine the sports movements and evaluate.

In some cases, the coach intends to compare players with each other to fix the team, which due to the lack of a suitable tool for measuring and evaluating athletes today, in most cases, people compete with each other, which is not an accurate indicator to evaluate them. Because coaches often hold these competitions shortly before the official competitions, the probability of physical and mental injury of the players due to the stress is very high, which affects the results of the official competitions. also, there are no means to evaluate yourself with others. Suppose a person enters an international competition but fails on the big field because he does not know his opponents' fitness factors.

Also, determining the appropriate training method to increase the level of physical fitness of athletes and achieve success in major Asian and global arenas, is an important issue that has caused serious challenges between coaches and athletes, and coaches have arranged their training in such a way that To increase the physical fitness of athletes. Therefore, to evaluate the effectiveness of training, measuring and measuring the main factors of the sport is considered, which due to the lack of appropriate facilities and tools to accurately evaluate the important factors of tennis during training, and considering that physical fitness plays a major role in sports activities and no athlete can succeed without having the desired physical fitness, choosing and using the appropriate ways and means to measure the motor abilities of athletes and then guide them to proper exercise and Properly covered, it will withstand a lot of adverse conditions.

For this reason, despite the above problems, it has been provided that athletes and coaches always easily observe, compare and improve the important factors required in the field of tennis in their training and evaluations. With this device, the coach can set and send a program wherever he is, and the athlete can practice or test with the program that the coach sent to the device. This device stores all the athlete information and sends it to the coach online and they can make the most of the coach's feedback on the results. In this idea, unlike similar ideas, the racket and the body of the amateur athlete who wants to learn the game of tennis are simultaneously monitored three-dimensionally.

The amount of correctness or mistakes of the athlete can be measured according to the similar behavioral movements introduced by the professional player as a model. This amount of similarity or difference is analyzed for each of the important items such as mobility, speed, or acceleration of hitting the ball with the racket as well as its three-dimensional angle and the level of similarity and difference of each of the important cases is informed to the amateur player so that he can correct his movements and blows. This idea can be a step towards holding competitions virtually by simulating all realistic conditions. Also, on the other hand, the conditions of the match can be simulated for the players in a completely real way so that they can fully experience the conditions on the day of the match.

Solution of problem

Tennis is a type of sport that is done using rackets and this sport can be played individually or in pairs. Special racket, tennis has a short and very strong handle and a small ball is exchanged between two people. The present invention is an intelligent racket in the context of the Internet of Things (IoT), and although at first glance it is very similar to ordinary rackets and its weight does not differ from ordinary rackets. This racket has several sensors and has intelligent functions that give it unique capabilities and distinguish this racket from other common tennis rackets. To make these rackets smarter, an application has been designed that registers smart racket information and in addition has other advantages that are mentioned below.

Using this smart racket, the user can get the difference between the size of his arm muscles, etc. With the desired person, and in this system, the level of play of two competitors can be checked based on some parameters, including simulation of muscle size. In this plan, the influencing factors in the individual game (in addition to techniques and game level) are estimated. In this way, the player can reach the most desired level in every aspect with proper bodybuilding exercises.

There are two methods we can use to calculate the number of user moves, one method is to install GPS on the player's helmet or headband to measure the amount of movement and the second method is to obtain the amount of displacement based on the calculation of the temperature map of the player (user).

To measure the amount and the number of passes of the ball from different directions and analyze which player has the highest percentage of attacks in which direction, for this purpose, using three LED lights, we divide the game tour into three parts and get the amount and number of balls passing through those three parts (right, middle and left). In this way, we better understand in which direction the player is more focused or from which side most of his attacks are.

In addition to the above, there is a sensor that analyzes positive words to encourage the player and stimulate him to play better, and in this regard, improves the game. In general, in the rackets and game nets, there are gyroscope sensors to measure the amount of vibration, and through this, 3D studies can be performed.

This racket can be paired with tablets, smartphones, and even smart TVs, which are connected via Bluetooth to mobile phones (or tablets) and can be connected and apply the necessary settings on the racket with the application installed on the mobile phone.

The designed application leads to various rotational movements of the player to move in the right direction. In such a way that the movements of the player's hand can be directed through the application, this movement is applied like a small blow on the racket. In this regard, these movements can be based on the movements of athletes appropriate to the level of the practitioner, so that the program is adjusted based on the simulation of the movements of competitors or professionals (which can be done at different levels). In addition, these movements can be reviewed by the sports coach and the appropriate program of movements can be adjusted by the coach.

This racket can be used with all kinds of balls and also has a high performance and a rechargeable battery. In addition to sending the history of movements and other measured items to the mobile phone, the racket also has internal memory and stores items.

This racket is designed so that you can use them to hold real-time competitions virtually and location-free. Real competitions are held virtually. As follows: Both athletes are in a space that has the conditions of the playing field but is closed. There are monitors in front of the eyes of these athletes who can see the opponent online and through these rackets, their competition can be held virtually. These competitions are location-free and do not require the physical presence of the players next to each other, and it is possible to hold competitions between players from different countries without the need to travel to a single place.

When training for competitions with these rackets, the environmental conditions are virtual reality. Consider a tennis player who lives in a city and has an important physical match in one city or even another country that is a different environment with different conditions (including having its weather conditions) and even the competition may be held night or day. This intelligent virtual reality system simulates all the conditions of the competition environment (including temperature, humidity, light) for the player and makes him have more effective training. For example, when a player has a match in Barcelona, all the environmental conditions are simulated for him. So the choice of location is virtualized with real space and these changes are real-time.

The simulation performed in this invention is so powerful that it even simulates the manner and direction of the wind using virtual reality. For example, if in real space, for example, the wind blows from the southwest for a few minutes and then from the south for a few minutes, all of this is simulated virtually.

In this invention, we used sensors to detect the movement pattern of the human body, in such a way that using the inertia sensors, the angle of the joints (for example, the angle of the joints between the shoulder and elbow) is examined. The point is that acceleration analysis here is not just linear and can be done both angularly and linearly and angularly.

This invention provides an innovative way to measure the non-linear acceleration of tennis in various modes of play and practice, including when hitting the ball. In this invention, all movements, sports-related behaviors, as well as the method of gaining a racket and hitting the ball in three main directions x, y, and z are carefully evaluated. This assessment is based on all points of the racket, including the four sides of the racket net and in two places of the racket category, in each of the mentioned points, there is a non-linear accelerometer (gyroscope) to measure the racket movements based on the same three main directions and actually in three-dimensional space.

These sensors are designed to accurately and realistically simulate the racket, and simultaneous monitoring of all six sensors can capture the racket's movements in three-dimensional space at any time. Each of the sensors momentarily announces its position to the central node or sink and based on it, an image is obtained. By continuously juxtaposing these images, a film of racket movements in three-dimensional space can be obtained.

In addition to monitoring the racket, the player's movements are studied in detail and three dimensions. In this way, by installing the same gyroscope sensors on the wrist, headband (or hat) as well as on the soles of the feet (player shoes) and the knees, we analyze the player's behavior and movement in three-dimensional space.

Using 3D analysis of the player's movement, in addition to studying his level of mobility during the game, we evaluate the correct or incorrect performance of all movements such as jumping, running, standing, and other important parameters of the user in the game of tennis.

In the next step, we will analyze the movement of the racket and the player in a three-dimensional space by combining the data obtained from the sensors inside the racket and the player's body.

In the next step, we analyze the image of a well-known and successful player using pattern recognition techniques (Pattern Recognition) and from that, we get a movement pattern for three-dimensional analysis of the racket's motion and the same elements of the sole (shoe), knees, elbows, and wrists.

In the next step, we will adapt the patterns obtained from the motor analysis of a person who wants to learn the sport of tennis in a principled and scientific way to the movement pattern obtained from the motor analysis of the model player (tennis champion) and the differences will be evaluated, in this way, the trainee is helped to adapt to the movements of the champion with the right program and to perform better in the sport of tennis.

In fact, in addition to the obtained parameters, it is possible to achieve the number of blows of the person being trained on the ball with a racket, the amount of mobility, the type of running and standing, and other important parameters in the game of tennis. The grade of similarity or difference between these movements and the movements of a professional player results in obtaining numbers that individually give points to the player under training. For example, the similarity of the mobility of two players (amateur and professional) is 60%, the similarity in the mobility of the two is 70%, these numbers are communicated to the amateur player and he can notice his strengths and weaknesses and try to eliminate the identified weaknesses.

If the amateur athlete detects weaknesses in the movements and kicks and repeats these cases, the system offers him special bodybuilding. For example, if a player performs a significantly weaker jump than the pattern, the system offers bodybuilding and leg agility exercises (as well as weakness in the hands, etc.). And all of this helps the amateur tennis player to learn properly and helps a person to become a skilled athlete.

On the other hand, given the professional player information, in another part of this invention, by connecting to Kinect game virtually, this player can play tennis or play tennis with a virtual opponent in an environment the size of a tennis court.

This player can also play with another real player who is also connected to the Kinect device in the real and virtual environment.

It is also possible to create conditions for the player to play tennis at a specific location.

For example, an amateur player can choose to be in the current city of Barcelona, Spain, and play with his authorized or real opponent, while our amateur player is located somewhere other than Barcelona.

To implement the above and environmental conditions at the same time (Real-Time) the game must be played indoors. In this way, for the player, the closed environment is considered to be about half of the tennis court (half of it) and then we measure the weather data of the desired city, for example, Barcelona.

After obtaining instant weather conditions through internet systems, we implement them as follows: for example, we make the room temperature or indoor space warmer or colder than the actual room environment according to the same air. In parallel, we activate the dehumidifier or dehumidifier system and also create the current wind direction and direction of Barcelona. The wind system is also activated by 8 fans that are in different directions north, south, east, west, southeast, southwest, northeast, and northwest. Even in cases where the wind is momentarily southwest for 3 seconds and west for 1 second, the fans are activated or deactivated in the same way. If the wind direction is one to two from both the east and northeast, the existing wind from the fans is adjusted in the same way. In addition to the above conditions, the user (amateur player) can change the environmental conditions to specific conditions. For example, choosing whether the competition space is night or day, whether it is rainy or sunny or cloudy, and so on.

The artificial intelligence system of this invention can predict the movements of the opposing player based on his records, and according to the tracing of the opposing player, it can also predict his future movements and inform the user (amateur player). This system is also quite effective for coaches and can be used because it enables coaches to better identify the strengths and weaknesses of their players and also test them in real-world situations.

With special settings, sound effects can be created in the same indoor space, and the significant behavioral differences of the amateur athlete with the pattern of the selected professional athlete can be informed by predefined sounds (just like a coach).

Finally, we analyze the movement of the racket and the player in a three-dimensional space by combining the data obtained from the sensors inside the racket and the player's body.
According to claim 13, the well-known and successful player analyzes the image processing using pattern recognition techniques (Pattern Recognition) and from it, a movement pattern for three-dimensional analysis of racket movement, and we get the same elements of the soles of the feet (shoes), knees, elbows, and wrists, and the patterns obtained from the motor analysis of a person who wants to learn the sport of tennis in a principled and scientific way and we adapt the pattern (tennis champion) to the movement pattern obtained from the movement analysis of the player and the differences are evaluated.
According to Claim 14, if the weakness of the amateur athlete's movements and blows is detected and repeated, the system offers him specific bodybuilding and due to having professional player information using the connection to Kinect game (line of motion measuring input devices) virtually this player can play with his virtual opponent.
According to claim 15, the artificial intelligence system of this invention can predict the movements of the opposing player based on his records, and by tracing the opposing player, he can also predict his future moves and inform the user (amateur player).
