Description

The invention relates to a game device for a kickback sport and a squash court.

A kickback sport is a ball sport in which two players or teams play a ball over a wall in accordance with a certain set of rules and try to force the opponent to make mistakes when accepting or returning them. Errors by one party lead to points of the other party and / or give the latter a right to serve. Squash is a setback sport. The kickback sport is also understood when a single player passes a ball over a wall. The wall can be a flat or curved surface or an edge. The ball is any means that can be played on the wall to bounce off it.

The setback sport is particularly appealing when it is played quickly, diversely and with playfulness. This requires that the players have a high level of fitness, especially high endurance and high speed. A player's game routine can usually be achieved through frequent training and varied game practice, which requires great mental stamina and a corresponding love of the player for the setback sport. However, the problem here is that less motivated players train with reluctance or even prematurely cancel an announced training program.

Both in mass sport and in the professional field, a coach can be hired to support the player, who motivates the player and supports him in the further development of his level of play. However, the possibilities of the trainer are limited, and the trainer cannot prevent the monotony that occurs to the player when playing or training the setback sport.

The object of the invention is to provide a game device for a kickback sport, a method for playing the kickback sport, wherein a player has fun playing the kickback sport and the player is trained effectively.

The object is achieved with the features of the protection claims 1 and 9. Advantageous refinements for this are specified in the further protection claims.

The game device for a kickback sport according to the invention has a playing surface to which a ball can be played by a player for bouncing off from a point of impact of the playing surface in accordance with a predetermined set of rules for the kickback sport and which has a sensor system which is set up two-dimensional first coordinates of the To detect the impact point and to transmit it to a computing unit of the gaming device, which is set up to determine two-dimensional second coordinates, a size and / or a shape of at least one target field as a function of the first coordinates in accordance with a predetermined rule, and to control a projector of the gaming device with the a projection surface lying within the playing area, the target field is projected visually for the player, onto which the ball can then be played by the player to bounce off the target field in accordance with the rules of the setback sport. The squash court according to the invention has the gaming device.

The method according to the invention for playing the kickback sport comprises the steps of: playing a ball on a playing surface for bouncing off a point of impact of the playing surface according to a predetermined set of rules for a kickback sport by a player; Detecting two-dimensional first coordinates of the point of impact; Determining depending on the first coordinates in accordance with a predetermined rule of two-dimensional second coordinates, a size and / or a shape of at least one target field; Projecting the target field onto a projection surface located within the playing surface, the target field being visually perceived by the player; Subsequently playing the ball to bounce off the target field according to the rules of the kickback sport from the player. The method preferably has the step: providing the gaming device according to the invention.

The playing surface is an integral part of the kickback sport according to the rules of the kickback sport. Because both the ball is played by the player on the playing surface and the target field is projected onto the playing surface in such a way that the player can perceive it, the playing surface serves both as a sports device and as a projection surface. The target field is used to indicate to the player where to play the ball next. The location of the target rock is determined on the basis of the location of the impact point and the predetermined regulation, taking this location on the playing field into account. Thus, by a corresponding two-dimensional offset between the point of impact and the target field on the playing surface, a varied and fast game can be requested from the player. For example, if the target field remains at the same place of the impact point, the reproducibility of the game is trained.

In accordance with the predetermined regulation, in addition to the location of the target field on the The size and / or shape of the target field can also be determined. For example, the smaller the target field is, the higher the demands on the player regarding its accuracy. For example, the size of the target field can vary in such a way that the target fields are made ever smaller in the course of the game, which means that the player is required to increase the accuracy of the target in the course of the game. Both aesthetic and tactical considerations regarding the setback sport can play a role in shaping the target field. For example, if the player is still a child, it may be attractive for the player if, for example, the target field has a heart shape or the like. Furthermore, for example, the shape of the target field can be selected such that when the ball hits the target field, it is difficult for an opponent to reach the ball.

By projecting the target field onto the playing surface as a function of the position of the impact point, the game of the player is guided in a targeted manner, whereby an intervention in the game of the player is made possible from outside the game action via the predetermined rule. Depending on the location of the impact point, the player is given an orientation with regard to the next game action on the ball by arranging the target field on the playing surface, the ball being intended to hit the target surface.

It is encompassed according to the invention that several target areas are projected onto the playing area at the same time, in order to give the player alternative goals for his subsequent game action. With the help of the predetermined rule, a corresponding choreography can be imprinted on the player's game, which means that the player has to complete tactical processes quickly. Furthermore, the choice of the predetermined rule can take into account the level of play, the form of the day and the purpose of the game, for example whether it is going to be hard training or whether the game should be played with ease and fun. By choosing the predetermined rule, a meaningful and attractive placement of the target field or fields can be achieved, with which a corresponding type and character of the setback sport can be imprinted. Without the game device and the method according to the invention, the imprinted type and character would be encompassed by the set of rules for the kickback sport, but in general the type and character only emerge in the case of randomly occurring moves. With the game device according to the invention and the method according to the invention, the game of the kickback sport can be predicted more than if the playing area were played by the player without the target field or fields. Thus, with the help of the gaming device and the method according to the invention, desired game moves can be impressed on the game, as a result of which the player is effectively trained and / or enjoys playing.

The predetermined set of rules is the well-known set of rules for the setback sport or a set of rules newly defined for the current game.

The sensor system is preferably a light barrier, in particular a light grid, for each of the two-dimensional first coordinates. The light barriers are preferably arranged on the edges of the playing surface, one of the light barriers being provided for the first coordinate, in particular the horizontal coordinate, and the second of the light barriers for the other of the first coordinates, in particular the vertical coordinate. A field is spanned by the light barriers on the playing surface, so that any location on the playing surface at which the impact point may be can be detected by the sensor system. The light barriers preferably each have a transmitter and a receiver, which are each arranged opposite one another on the playing surface, light from the sensor being able to be emitted in the direction of the receiver for receiving there. If the ball strikes the impact point, the ball interrupts the corresponding light path from the transmitter to the receiver, whereby the corresponding coordinates of the impact point can be detected. The transmitters preferably emit pulsed light, which saves energy compared to the emission of continuous light. The pulse lengths of the pulsed light should be selected so that the presence of the ball can still be detected given the relatively short dwell time of the ball at the point of impact.

Alternatively, it is preferred that the sensor system has a light barrier, in particular a light grid, for one of the two-dimensional first coordinates and for recording the playing surface, a camera with an image evaluation unit with which the other of the two-dimensional first coordinates can be detected. One of the first coordinates, for example the vertical coordinate, can be detected with the aid of the light barrier. The camera continuously records the playing surface with a correspondingly high frame rate, the ball advantageously having to stand out from the playing surface in high contrast. When the ball is played, the images from the camera show the ball's flight towards the playing surface, the impact of the ball on the impact point and the bouncing of the ball off the playing surface. The image evaluation unit of the camera is configured in such a way that the point of impact of the playing surface is located on the basis of the recordings of the camera Can be detected in real time, so that the other of the two-dimensional first coordinates, in particular the horizontal coordinate, can be derived. To determine the other of the two-dimensional first coordinates by the image evaluation unit, in particular the speed and the direction of the ball before and after the impact with the impact point and / or with the impact on the impact point are used.

The gaming device preferably has a server with which the predetermined rule can be input into the computing unit and / or manipulated in the computing unit. Furthermore, the gaming device preferably has a client computing unit with which the predetermined regulation, in particular via the server, can be entered into the computing unit remotely and / or manipulated in the computing unit. As a result, the predetermined rule in the computing unit can preferably be configured in a variety of ways, in particular by remote access. For example, the predetermined rule can be stored as software in an app that can be controlled via the Internet or other remote access technologies. This makes it possible, for example, for numerous regulations to be stored in software in a database, which can be called up from this database for a special application of the gaming device on site.

Furthermore, the sensor system is preferably set up to detect an impact of the ball in at least one target field and to be coupled to the computing unit for reporting this detection back to the computing unit. In addition, the computing unit is preferably set up to evaluate the feedback and to control the projector in such a way that evaluation information is projected onto the projection surface as an evaluation display. This advantageously provides the player with information about the success of his game via the projection onto the playing surface, for example the hit rate with which the player hits the target fields predetermined for him. It is also possible to receive the evaluation information via the server with the client computing unit and thus to provide the player with control from a distance.

It is preferred that the kickback sport is squash and the playing surface is encompassed by an end wall and / or a side wall and / or a floor of a squash court. Alternatively, it is preferred that the playing surface has an uneven shape, in particular a cylindrical or a semi-cylindrical shape. In addition, it is alternatively preferred that the playing surface is formed by an edge, the ball in particular being a ball. In this case, the kickback sport would preferably be billiards.

In order to provide feedback on the quality and / or the quantity of the game to the player himself and / or to a client, the method has preferred steps: projecting the target field onto a projection surface located within the playing surface, the target field being visually perceived by the player; Subsequently playing the ball to bounce off the target field according to the rules of the kickback sport from the player. Furthermore, the method has the preferred steps: detecting an impact of the ball in at least one target field; Evaluating the feedback and projecting evaluation information as an evaluation display on the projection surface.
