Description

The present invention relates to an optical device comprising a ground unit 14 and a projector unit 15 for dynamically reconstructing or simulating competitive situations and promoting sports training, the optical device ensuring the reconstruction or simulation of competition situations by projecting different geometry and / or color spotlights onto a sports field surface and moving them in a predetermined direction in a predetermined manner moving at a certain speed.

The prior art will be described below. In competitive sports, the training sessions prepare the participant for the competition. An athlete can only make the most of his performance in competitions or matches if he is regularly exposed to high levels of stress during training, even for only part of a task or in decision-making situations such as in real competition. The reconstruction and implementation of the competition load and the competition situations in training sessions has been almost an impossible task for athletes and coaches so far.

The device we developed is technically the closest to the devices used to manufacture laser shows and laser projectors, which is why we will take a closer look at the relevant features below.

Laser show. In this case, a different pattern can be drawn with a fast, controlled movement of a single laser beam. The point here is that the single point of the laser in the device is moving at a speed that merges into a continuous curve of points for the human eye at different spatial locations and produces an image of a coherent shape in the brain. As a result of the technique most commonly used, only contours are drawn, but to obtain a superficial pattern, "satirization" is required. The desired lighting effect is usually solved by a double mirror galvo machine controlled by computer software. This allows the controlled deviation of the laser beam in the xy direction, ie the drawing of the forms provided by the control computer. The equipment itself is quite simple and usually does not include any other serious optical system. Such technical solutions are described, for example, in the following Internet sources, the download date being the priority date of this patent application:

In order to achieve more spectacular patterns, not only a laser of a certain color is used, but also up to 34 different colors, which are each kinked individually. Examples of such solutions are the following resources: http://www.lh-laser.com/views.asp?hw_id=358

500 mW) als Lichtquellen eingesetzt. Da diese Leistung in wenigen Millimetern ausgeprägt ist, ist die Intensität der Oberflächenbeleuchtung an einem bestimmten Ort groß, was beim Erreichen des menschlichen Auges zu erheblichen gesundheitsschädlichen Auswirkungen führen kann.In order to see the shapes drawn in this process in large dimensions for a large number of spectators, relatively high-powered lasers (

500 mW) as light sources. Since this power is pronounced in a few millimeters, the intensity of the surface lighting at a certain location is large, which can lead to significant adverse health effects when reaching the human eye.

Laser projector. The main element of a typical laser projector is the laser, which operates at three different wavelengths, namely the primary colors R, G, B (red, green and blue). For the necessary color mixing, the three laser beams should be merged into a single parallel beam. Normally a white beam of light is generated. In order to achieve the color effect to be ensured on the screen surface, the light intensity emitted by these three lasers must be modulated and in some way controlled independently of each other in order to bring them in line with the image content to be displayed. The combined beam and the color of the pixel produced by it on the screen can be changed from time to time by precisely adjusting the RGB ratios, by mixing the primary colors with the corresponding intensity. This control agrees with the data of the visual parameters for the image to be projected. The mixed beam formed by the three laser beams must be moved through the parameters in accordance with the known imaging standards so that the pixel produced by it "scans" the projection surface. In the case of laser projectors we can not speak exactly of projection, because the picture is not in one Piece is shown at once and the image is not displayed as in conventional projectors, but by the very fast movement of a single point of light, which is generated by the mixed beam directly on the screen. This means that the beam should be redirected from a moving system in the xy direction by pulling that frame from row to row, from column to column. See, for example, the US patent document US7756174 ,

The most important steps of the imaging process are therefore as follows: 1) Digitizing the projected analog image signal with the control unit and then routing to a buffer. 2) Next, the color transformation that ensures the color compatibility between the color space of the RGB laser and the TV / video system. The transformed RGB data are passed to the laser modulator, where they are converted by means of intensity modulation through the channels R, G, B into optical information. 3) Then the correct pixel deflection, the projection can take place. For horizontal deflection, a rotating polygon mirror at 1300 / s lap is often used. This is followed by a galvanometer mirror motion system that performs a vertical deflection. In order to move the galvanometer mirror, such Galvanomotoren are used, as in the patent US8031386 disclosed.

In recent years, the jet motion technology has been further developed. With a simple, smooth mirror, the mixed beam is projected onto a "biaxial" MEMS (Micro Electro-Mechanical Systems) scanning mirror, which performs the optical deflection of the laser beam. This integrated electromechanical-optical device, more precisely, the mirror inside, can also have a fine, controlled movement about the vertical and horizontal axis. Such a solution is for example in the patent US8638446 disclosed.

The projected laser beam emits directly from the MEMS scanning device and produces the image in front of the projector on each surface the beam reaches. The output radius is also divergent, as is the increase in image size and the increase in pixel size. The result is a sharp picture at every distance.

That is, as long as the image projected by the laser projectors is approximately sharp everywhere, the sharpness of the conventional projector must be permanently adjusted after changing the projection distance, and parts of the image become blurred when projected onto a surface that is not evenly spaced from the device is. This can for example be a flat surface if the orientation of the projection is not exactly vertical, but also any three-dimensional surface.

US458888887 The patent discloses an optical display apparatus wherein the light source is an Injection Laser Diode (ILD) wherein the path of the laser light from which it is first interrupted by a fixed mirror and then by a galvanometer mirror which is rotatable about a longitudinal axis is, wherein the movement of the rotatable mirror is realized by a vibrating galvanometer (resonant galvanometer).

US4762994 Patent discloses an optical scanner in which the light source is a laser and in which the laser light path is interrupted by a scanning mirror. The oscillating movement of the scanning mirror is also solved in this case with the vibrating galvanometer. A similar system is disclosed in the patent US20050128553 disclosed, wherein the disclosed system is used for example for the production of printed circuit boards.

US6344917 Patent discloses a galvanomirror device that can be used in an optical disc drive, wherein the direction of the laser light is changed by the aforementioned galvanometer mirror.

We know nothing about the sport application of projected dynamic directional light. In industrial manufacturing technology, a layout for practicing assembly steps is already in use, in which, for example, a conventional video projector, which stands above a desk, projects the textual and graphical information required during the learning process.

For the purposes of use in sports is based on the patent HU222643 B1 (Apparatus for facilitating the training and the practice of ball games), which describes the operation and the applicability of a device in which light signals are used to promote ball games. The equipment is based on a rigid frame and a translucent ball, which makes the training board accessible to the ball players. The practice board consists of several individually illuminated fields, behind which is a segmented light source. The main goal of the training is to practice the throwing, kicking and fixing of the necessary movements, dynamic and kinematic. By illuminating the area according to the trainer's concept, the field in the board is assigned to the training player to be addressed, and the athlete tries to get the ball to that point. The referenced patent and design we invented have only in common, as both are used for training purposes light signals used. Independently of differ both the illuminated area (full track vs. multi-segment practice board) and the type of lighting (mirror-based scanning with LED or laser illumination vs. fixed lighting, segment lighting) as well as the specific use (determination of the direction of movement of the player vs. target area to be evaluated) ,

The technical problem to be solved by the invention is that an athlete in training can not only get theoretical instructions for the motor sport movements expected by the athlete, but also can see and execute the required motor movements in practice during a reconstructed or simulated competition situation so as to achieve precise control of the athlete. The technical problem to be solved by the invention is also that it is possible to instruct several athletes precisely to move simultaneously during training.

The foregoing objects are achieved by the present invention by a discovery based on the ability to reconstruct or simulate competitive situations by an optical device designed to project and illuminate directional headlamps of different geometry and / or color on the surface of a sports field to move in a predetermined way in a certain direction and at a certain speed. The aforementioned optical system allows more precise control of the simultaneous movement of several athletes at the same time.

We have developed a new device for the production of spotlights, which allows the dynamic reconstruction of competitive conditions that can achieve a sufficiently high level of brightness, pattern and rate of change on a particular sports field surface in the desired lighting form. The invention will be described in more detail with reference to the accompanying drawings.

FIG. 12 is a block diagram of the major parts of one embodiment of our developed device. FIG. The device includes a ground unit 14 located at the point of application, for example, on the edge of a field, which is available to the trainer as an assistant; while the other element, the projector unit 15 , which is located above the sports field, the track, in a known height. The position of the projector unit 15 is determined by the task to be performed and the location geometry. They can be attached to the holders of the bulbs, on their own stand, on the ceiling in the case of a gym or other fasteners, for example. An additional mounting solution is the installation of the projector unit 15 on a well-controlled drone with spatial position, resulting in a much more flexible device. The projection unit 15 includes a radio frequency receiving unit 1a , a control unit 1b and 21 . 22 . 23 .... 2n Light sources - beamforming optical scanning unit systems, wherein the light source - beamforming optical - scanning unit systems 21 . 22 . 23 ... 2n comprise one or more 4 light sources, a mechanically coupled 3-beam optical unit and 2 scanning units.

The ground unit 14 includes a control computer 6 and a high frequency transmitting unit 5 , The position database to be projected should be the control computer 6 The position database is provided by software for the projection unit 15 converted. Depending on the training task, the database can be purchased or created with the GPS coordinates of our own athletes. The computer program then converts the input data, using the projection unit 15 the corresponding pattern is projected to the appropriate location and moved at the desired speed in the specified direction. Here, three tasks must be solved simultaneously. First, we need to create a user interface that allows the trainer to input the desired combination of motions and translate it into accurate physical geometric data (spatial positions, velocities, directions, etc.) and then instructions to the projector unit 15 which then realizes this combination of movements. The connection between the control computer 6 and one or more scanning units 2 is to be ensured by a multi-channel RF communication unit.

For purposes of the present invention, examples include the control computer 6 including personal computers, laptops, notebooks and tablets.

The RF receiver unit 1a in the projection unit 15 receives signals from the ground unit 14 and send it to your own control unit 1b , Based on the instructions, this device controls the configuration. This controller 1b represents the one or more light sources 4 , the number of light signals to be projected, their shape and the path of their movement. The projector unit 15 comprises at least one optical scanning unit system for light sources - beam forming. The light source beam-forming optical scanning unit system includes light sources 4 , beam-forming optical units 3 and scanning units 2 , The number of in a given projector 15 integrated optical scanning units for beam shaping of such a light source can be increased according to the needs of the user and the requirements of each task. The power supply of the device can be solved by an electrical power source or batteries. In the case of a drone installation, only one battery may be used, while in a fixed rack the network power supply can be safely secured.

1. 1. Das am Boden erzeugte Lichtmuster muss für die am Training teilnehmenden Athleten sichtbar sein. Um dies zu erreichen, ist es notwendig, eine ausreichend hohe Intensität zu erzeugen und andererseits eine angemessene Beleuchtungswellenlänge zu erzeugen, die den optischen Eigenschaften der jeweiligen Bodenoberfläche entspricht. Die richtige Auswahl dieser beiden Parameter gehört zum Wissen des Fachmanns. Es macht einen Unterschied, ob eine Rasenfläche gut sichtbar sein muss, oder auf Parkett, Asphalt, Kunststoff, Gummi usw. auf befestigtem Boden.
2. 2. Es ist darauf zu achten, dass ein oder mehrere Lichtstrahlen 7 keine Gefahr für den Athleten, Trainer, Beobachter, Zuschaueraugen, körperliche Integrität darstellen. Nach unseren Voruntersuchungen würde ein Scheinwerfer mit einer Durchmesserabmessung von ca. 10 cm und einer Angabe davon auf dem Feld gut erkannt und verfolgt werden. Für diese Aufgabe eignen sich relativ stromsparende (ein paar Mal 100 mW) Laser und die sich in letzter Zeit dynamisch entwickelnden, leistungsstarken (wenige Watt) LED-Lichtquellen am besten zusammen mit ihrem Netzteil. Unsere Vorversuche zeigten, dass 3-4 Farben (rot, gelb, grün, möglicherweise blau) alle gängigen Deckungsarten abdecken. Dementsprechend werden, ohne darauf beschränkt zu sein, zwei Arten von Geräten als bevorzugte Ausführungsformen offenbart. In der einen sind nur eine oder mehrere Lichtquellen 4 mit Wellenlängen für eine benutzerdefinierte Größe integriert, während die andere zwei oder mehr Lichtquellen 4 hat, die zwei oder mehr Farben beleuchten, so dass die Vorrichtung universell auf alle Arten von Abdeckungen angewendet werden kann. Durch den Einsatz von drei Farbkomponenten (rot, grün und blau, RGB) Lichtquellen 4, die beispielsweise, aber nicht beschränkt auf einen Laser oder eine LED, sein können, kann theoretisch jede Farbe verwischt werden, wobei jedoch die Lichtstreuungsfähigkeit der zu beleuchtenden Oberfläche bei den Wellenlängen der Grundfarben berücksichtigt werden muss. Damit sich das System an die aktuellen Lichtverhältnisse und Streueigenschaften des Bodens anpassen kann, müssen eine oder mehrere Lichtquellen 4 steuerbar sein. Mit einer so komplexen Ausrüstung wird es möglich, mehrere farbcodierte Informationen zu projizieren.

One or more of the light sources used 4 During lighting, they must meet the following basic requirements.

1. 1. The light pattern generated on the ground must be visible to the athletes participating in the training. To achieve this, it is necessary to generate a sufficiently high intensity and, on the other hand, an adequate level of intensity To produce illumination wavelength, which corresponds to the optical properties of the respective ground surface. The correct choice of these two parameters belongs to the knowledge of the expert. It makes a difference whether a lawn needs to be clearly visible, or on parquet, asphalt, plastic, rubber, etc. on paved ground.
2. 2. It is important to make sure that one or more beams of light 7 pose no danger to the athlete, coach, observer, spectator eyes, bodily integrity. According to our preliminary investigations, a headlamp with a diameter of about 10 cm and an indication of it on the field would be well recognized and tracked. For this task are relatively energy-efficient (a few times 100 mW) Lasers and the recently developing, powerful (few watts) LED light sources work best together with their power supply. Our preliminary tests showed that 3-4 colors (red, yellow, green, possibly blue) cover all common cover types. Accordingly, but not limited to, two types of devices are disclosed as preferred embodiments. In one are only one or more light sources 4 integrated with wavelengths for a custom size, while the other two or more light sources 4 which illuminate two or more colors so that the device can be universally applied to all types of covers. Through the use of three color components (red, green and blue, RGB) light sources 4 For example, but not limited to a laser or LED, theoretically any color may be blurred, but the light scattering ability of the surface to be illuminated at the wavelengths of the primary colors must be considered. In order for the system to adapt to the current light conditions and scattering characteristics of the floor, one or more light sources must be used 4 be controllable. With such a complex equipment, it becomes possible to project multiple color-coded information.

The beam-forming optical unit 3 is with respect to the 2 and 3 shown. One or more light sources 4 are equipped with optical elements (lenses, mirrors, apertures / masks, optional programmable spatial light modulators (SLMs), etc.) to perform the required tasks and provide the required projected shapes. The first element of one or more of the beam-forming optical units 3 is the beam deflection optics 8a , His job is that of the light source 4 emitted light beam 7 to convert to the appropriate size and the corresponding diameter, so that the responsible for the formation of the given beam shape surface of the aperture plate or the spatial light modulator (not in the and shown) can be completely illuminated, but no longer loses light intensity.

As in the 3 and 4 shown illuminated to the appropriate size light beam 7 in the second step, the beam-shaping unit 8b (not in 4 shown) in the in 4 illustrated embodiment equipped with holes of different shape perforated plate 10 is that of one of a control unit 1b (not in 4 ) controlled electric motor is rotated, whereby the desired pattern is projected. In a further embodiment, the beam-shaping unit 8b (not in 4 represented) a spatial light modulator 13 in that the corresponding beam pattern can be generated by the pixels (opaque pixels: 11, transparent pixels: 12) generated by the control unit 1b (not in 4 shown) can be switched on and off (variable throughput). With the aid of the aforementioned elements, it is possible to realize that using a light source - beam forming - optical - scanning unit, which corresponds to the number of athletes to be controlled, each athlete has a different beam shape.

For the purposes of the present invention, the terms "beam forming unit" and "opening" are used interchangeably.

• i) In einer Ausführungsform der Vorrichtung nach der Erfindung verwendet die einfachste Lösung ein ausreichend kleines, sogenanntes kollimiertes Licht ( ), wenn die die Öffnung verlassende Strahlform das Feld beleuchtet. Die Größe der projizierten Form kann durch die Divergenz (Verzerrung) und den unter bestimmten Grenzen einstellbaren Projektionsabstand des Lichtstrahls 7 beeinflusst werden, und der Projektionsort wird durch die Abtasteinheit 2 bestimmt.
• ii) In einer weiteren Ausführungsform der Vorrichtung gemäß der Erfindung gibt es weniger Anforderungen (z.B. Kollimierbarkeit) an eine oder mehrere Lichtquellen 4, wenn die (auch divergierenden) Strahlen der Strahlformungseinheit 8b durch eine Abbildungslinse 9 zur Abtasteinheit 2 gelangen (3). In diesem Fall wird das Bild der Blende mit optischer Bildgebung projiziert, die Größe des Bildes wird durch die Winkelvergrößerung des optischen Systems und den Projektionsabstand beeinflusst, und die genaue Position der Projektion wird ebenfalls durch die Abtasteinheit 2 bestimmt.

For example, that of the beam-shaping unit 8b produced form can be projected into the ground by the following two methods.

• i) In one embodiment of the device according to the invention, the simplest solution uses a sufficiently small, so-called collimated light ( ) when the beam shape leaving the aperture illuminates the field. The size of the projected shape may be due to the divergence (distortion) and the adjustable within certain limits projection distance of the light beam 7 be influenced, and the projection location is by the scanning unit 2 certainly.
• ii) In a further embodiment of the device according to the invention, there are fewer requirements (eg collimability) to one or more light sources 4 if the (also divergent) beams of the beam-shaping unit 8b through an imaging lens 9 to the scanning unit 2 reach ( 3 ). In this case, the image of the aperture is projected with optical imaging, the size of the image is through the angular magnification of the optical system and the projection distance, and the exact position of the projection is also determined by the scanning unit 2 certainly.

The task of the scanning unit 2 is that through the molding unit 8b guided light beam 7 with the desired parameters to project the light beam to the earth's surface. In a preferred embodiment of the invention, the scanning unit 2 a commercially available mirror scanner. Said mirror scanner comprises two highly reflective mirrors at the applied wavelengths attached to galvo motors according to conventional scanning geometry. The size of the mirror is determined by the beam shaping unit used 8b and optionally by the imaging optics 9 determined, the speeds and the positioning accuracy of the Galvomotors largely meet the requirements of our devices. The position and movement of the two motors and thus the mirrors on them are from the projector to the 15 belonging control unit 1b set according to the current task.

Of all the components described above, the device thus constructed differs from the previously used training aids. Its high flexibility makes it unique in this area. It is possible to project static and dynamic patterns, and the shapes of the directional emitters used can also be changed during exercise. The high-precision setting of the scanning unit makes it possible to provide each point of the trained field with sufficiently accurate localization and dynamics (it is not necessary to divide and segment the field area into a certain number of cells). The number of players participating in training can be easily expanded by switching on new units. The representation of the desired shapes on a field does not require any change in the surface area of the field, this will be explained later.

The device according to the present invention can also simulate games and competitions on an international level better than any technology that supports the previous training.

The device of the present invention provides one or more athletes with a more direct and accurate signal or signals than the prior art of the expected locomotion movements, no matter how complex, thus opening new horizons and opportunities for team development and analysis to athletes. These locomotive moves can be directly displayed to the athlete: whether it is a tournament or a game situation, or a complete tournament or match, or even the move of a previous athlete or other athlete movement, and even the ball path in ball games. An embodiment of the present invention also enables the projection of a large number of athletes, team members, entire teams or even more teams. The projection is done with geometric figures in two dimensions from top to bottom, covering the respective sport. The job of the athletes is to follow the change in the location of the geometric patterns around them. The athletes are instantly able to perceive the expected movements, their direction, speed, rhythm and the difference between their own and expected movements in real time in a competitive situation in the same room as the game. As desired, either in real time or in the initial stages of the exercise, any required movement can be seen by the athlete, even slowing down or accelerating at any desired speed.

In contrast to the techniques known in the art, the athlete not only receives theoretical instructions with the device according to the invention, but also sees them directly in practice in the simulated competitive situation. This allows for almost immediate correction and even more efficient training.

Through the valuable, high-quality training in simulated racing situations, an increase in performance can be achieved. It is a unique feature of the invention that the physical condition, the strategic, tactical skills, the combined movement, the thinking, the speed of decision-making, the creativity of the athletes and teams, their cognitive skills and their cooperation can be effectively developed.

With simulated competition situations, new tactical and individual solutions, team-based solutions and elaborate versions of them can be practiced or even previously misdirected situations can be projected to find and practice the right solutions. The practiced variants are added to the tactical repertoire of the team and developed the game intelligence of the athlete.

The configuration can be stopped at any time, after which the athlete has to choose a creative solution for the respective competition situation, for individual training, for tactical training or team sport for the development of teamwork. By stopping the projection in a simulated competitive environment, using the device of the present invention, the athlete is placed in a decision situation, and with independent solutions, creativity, the speed of the decision-making mechanism, efficiency and, in the case of a team game, cooperation can be significantly improved. The evaluation of the performances presented offers the coaching staff a broad spectrum of analysis options and thus enables the development of athletes.

The device according to the invention offers an improved performance of the training compared to the prior art and thus achieves faster and more spectacular results.

An embodiment of the present invention provides an application for promoting football training.

In football, the game load can not be reconstructed with buoys, with weapons, either at team or part team level or individually. No defensive or defensive movement can be reconstructed with pickets or buoys, even for a simpler attack, as it would model a static state and not have the proper movement speed, rhythm, timing, and angle of direction changes. Since football is not a cyclical sport and involves extremely complex movements, it becomes even more difficult to reconstruct game, competitive, competitive, competitive and decision situations that can be accurately simulated by one embodiment of the present invention.

According to one embodiment of the invention, it is a significant innovation in the promotion of football training that it can give players daily or even subtasks new impulses to the players, to the level of international games essential for the development and maintenance of the competitive form. Not infrequently, athletes are unable to gain access to training during team play as they know each other's skills and patterns and perform the same training.

Another limiting factor may be that the players within a team have a similar level of fitness. Although differences in fitness level can occur between individuals, depending on certain genetic conditions, the current form, different levels of motivation, and other factors, they can not influence the overall fitness level of an entire team. If some athletes are still able to influence the fitness of the entire team, this can already be considered the overall fitness of the entire team. The impact of less player performance on an entire team can not be effective enough for the development of the team and are sufficiently effective, for example, because they do the same training, they know each other's abilities and movement patterns and because the players have one showing better performance are always limited by the weaker performance of their teammates. Because team members inadvertently constrain each other in their development, they need a new impetus, a realistic matchload - even for subtasks - and decision-making situations for development. It is a good example of single-game training, in a fight the race between two genetically different players. If the faster player can dismount the other player within 10 yards, then he will not overtake him by 3 yards, then turn back and make more distance in the sprint because it would not make sense in this match fight. However, the slower player restricts the development of his teammate as he does not force his companion to intensity and length of the sprint (not to mention rhythm, directional change, and many other important factors); but he will, for example, in a game situation the faster player of the opponent. A similar problem exists e.g. with differences in knowledge or motivation or with different abilities. As a result, a player with a better ability is not forced to get the most out of his training, which is limited by his partner's weaker performance. For this reason, he can not develop properly, can not reach his genetically determined maximum performance, his development may stagnate, his performance and competitive form may deteriorate.

According to one embodiment of the invention, even complete international matches or halftimes can be projected for physical development, which players must track per position. This can not only improve, but also measure the physical performance of individuals or even the entire team. It can also be integrated in subtasks in the daily routine.

According to one embodiment of the invention, it is possible to present an action, sequence or run of an elite player as part of an individual training either from an international game and thus give the player the necessary impulse for the training.

The projected movement can be performed either by a defender or a striker, individually or even in pairs, even in defensive or offensive tasks. An embodiment of the device according to the invention can also project the path of the ball, so that the task can also be carried out as a ball exercise. This task will help us to find out exactly where the elite player has taken the rank, how fast he was and in a rhythm he has made, how much distance he has had from the opponent in the match fight, and what angle he has changed the direction and how he started the sequence at the end of the line of movement, which further supports this development process. First, any movement can be slowed down, then it can be projected in real time or accelerated. The projection can be stopped at any time to leave the player in decision-making situations and to let him choose the right solution, thereby developing the creativity, speed and efficiency of the decision-making mechanism. Choosing the right solutions in decision-making situations and their improved versions, new variants of prepared and projected solutions to the past mistakes will improve game intelligence and individual abilities.

According to one embodiment of the present invention, it is also possible to prepare the current emerging opponents by projecting their movements.

According to another embodiment of the present invention, not only the predetermined competitive positions can be projected, but also the simulation of fictional, preconstructed situations.

The device according to the invention also offers many new applications in the field of tactical training and the development of teamwork. As long as tactical instructions could only be given to players on a board, tablet, or orally on the football field (otherwise the movement of the team could not be demonstrated), they can now be shown on the field in practice.

The device according to the invention allows a more precise control of the combined movement of several players simultaneously, which has so far been only superficially discussed, who and how will move to practice a tactic, and when it came to show exactly who and where the coach could only instruct a single player or at the same time some players. The simulation of realistic game situations in training and the practice of tactics is even more difficult. With the device according to the invention, entire parts of a team or the entire team or even several teams can be controlled, instructed and moved in real time by being slowed down or even accelerated.

The device according to the invention also offers the possibility of stopping the projection at any time, so that the actors can be placed in decision-making situations and choose the appropriate solution themselves, thus developing their creativity, speed and efficiency in decision-making and excellent for developing the interaction contribute. By practicing the improved solutions chosen in the decision-making situations and their revised versions, as well as the prepared and projected new tactical variations and solutions to correcting previous mistakes, the team's tactical repertoire is expanded and its team play developed.

The device of the invention enables a lifelike simulation of game situations, regardless of whether it is to be corrected preliminaries, predefined movements or movements of other teams. For example, the ball played by an elite team may be projected, pass the ball, or counterattack after the ball is lost, or as an offensive team resolves the other team's defense in an international match. It can be shown how an attacking elite team shifts in certain situations: how fast, in what part of the field, in what kind of position, in what form and how far away the players are.

Attacks or even defense in different formations belonging to such attacks can be practiced. By projecting the ball pattern, the ball performance of the elite team can be analyzed and some parts practiced, for example: The pass speed, their directions, solutions in decision situations and the ball-free movement of the players can be simultaneously simulated.

The apparatus of the invention provides an accurate picture of the choice of other professional athletes in certain game situations, of the moves chosen in terms of tactics and interaction, and of how an elite player performs throughout the game on the territory of the field emotional.

The apparatus of the present invention also provides the ability to analyze the current opponent. It is also possible to analyze some of the enemy's strategically important attacks by practicing the defense against them, or projecting and practicing the mistakes in the defense of how to exploit them. The players can already experience the movements of the opponent, their speed, their rhythm and their direction in training Feel what makes preparing for the game easier and helps the team to achieve victory and success.

The invention allows the use for the facilitation of athletic training.

The invention makes it possible to project the given run of the athlete or runs in previous competitions or runs of another athlete on the runway in the context of a sports training and so to simulate the competition.

The projection can be used to determine the desired speed and rhythm of running, thereby developing a strategy for running the athlete in a tournament or training, analyzing another athlete's previous run, or physically developing that athlete.

The invention allows a particular athlete to perform certain distances within certain seconds during a particular workout, or even several times in a row, also slowing down the course of an earlier personal best of that athlete to the desired extent, depending on what preparation phase is performed and what he does would like to develop.

The invention provides a projection for development, practice, analysis such that the 400 meter run of a top athlete is performed, i. the speed of a certain part of the run is simulated.

The invention offers a projection of the personal best from the jump of the athlete or from the jump of another athlete in the context of a high jump training.

In the following, the use of the device according to the invention in some other sports is mentioned, without limiting the invention. The invention should be applied by simulation of competitive situations, complete competitions, for the purpose of development, analysis and taking into account the characteristics and characteristics of the sport.

The invention provides an application for the promotion of American football training.

American football is much shorter compared to European football, and the attack is more often started from fixed positions when players have the opportunity to take their positions in advance. Therefore, the tactic can be even more important. Since the game consists of short sections, it can be built more accurately, attacks and defenses can be practiced. The players use dozens of prepared tactical variations. Their training, analysis and development is much more efficient and efficient with the equipment of the invention.

The invention makes it possible to use rugby training.

The invention is an application for the promotion of car and motor sports training.

The invention enables the formation of an ideal curve on the track in front of the racer, preferably with specification of the degree of acceleration and deceleration, its position and the maximum speed that can be taken safely for this particular curve.

The invention provides an application to facilitate the training of young racing athletes.

All the advantages of the invention described in detail receive great importance in the context of the training of young athletes. For younger racing athletes, the concrete goal to be achieved, the level at which they later have to adapt physically and mentally, becomes visible.

The invention enables the use of recreational sports activities.

The present invention allows the use of recreational use by noncompetitive athletes, even when required, which slows down the projection. Broad masses can be addressed and involved in the world of exercise and sports, whether they are children or adults. The programs of general and secondary schools, colleges, leisure centers, sports complexes, hotels and adventure parks, for example, in real time or in slow motion a real, legendary game in which participants can test their physical skills, tactical skills and gain real fun to part to become a famous game and feel like a world-class athlete.

With the aid of the invention, it is possible to simulate competition situations directly and to complete competitions directly by projecting the movement of one or more athletes in practice. In this way, the individual abilities of the athletes, the physical condition of the athletes and teams, their strategic, tactical readiness, their combined movement, their thinking, the efficiency and speed of their Decision-making, their creativity, their cognitive abilities, their game intelligence and interaction are improved. The athletes are immediately able to perceive the expected movements, their direction, speed, rhythm and the difference between their own and expected movements in real time in a competitive situation in the same room as the game. As desired, either in real time or in the initial stages of the exercise, any movement needed by the athletes can be seen, even slowing or accelerating the movement at any speed.

With the device according to the invention, in contrast to the prior art, the athlete not only receives the instructions from the theoretically expected locomotion movements, but also sees them directly in practice in simulated racing. This gives us the opportunity for almost immediate correction and even more efficient training.

The projection can be stopped at any time, after which the athlete individually chooses a creative solution for the respective competition situation in order to carry out a tactical training or teamwork for the development of a team. With the help of this innovation, in a simulated competitive situation, by stopping the projection, the athlete gets into decision-making situations, and with the individual solutions given to him, creativity, decision-making speed, efficiency and teamwork can be significantly improved.

Among other things, the advantage of our equipment is that it can be used for common field types, does not require conversion, modification or handling of the existing surface of the field. It is not necessary to introduce new types of coatings which would most likely alter the known and common physical parameters of the fields (e.g., friction, flexibility, stiffness, etc.), i. create different conditions for training athletes.

The representation, projection of a particular pattern on the field requires e.g. no transparent covers, no substructure (structural elements under the floor) is required. All of this is important because the altered physical parameters can affect athletes' performance, musculature, endurance, and reversal technique, as well as their development under realistic circumstances. For example, when running on asphalt cladding or on lawns, it has a very different effect on the athlete's muscles, joints and skeleton. On the other hand, the replacement and modification of the covers would cause significant additional costs. Another advantage of the system is that it can be used in snow, dirt and mud.

The apparatus of the invention can be used to detect and correct errors, analyze each situation and the performance of an athlete or opponent. By practicing some elements and their improved versions, the strategic, tactical repertoire can be extended. In an unprecedented way it is possible to control the combined movement of several athletes. The evaluation of the performances presented offers the coaching staff a broad spectrum of analysis options and thus enables the development of athletes. It raises your training to a new level and achieves fast and spectacular results.

In order to perform best in athletes' competitions, they need to train in competitive situations, competitive pressures, decision-making situations and need new impetus for the development and preservation of the competitive form. The present invention provides this support, and the versatile simulation of competitive situations can increase the efficiency of the training to an unprecedented level, opening new horizons for the development of athletes and teams to help them succeed.

In the following, the invention is illustrated by means of examples, which should not be construed as limiting the invention.

EXAMPLES

Example 1: Use of the present invention to support high jump training

For the athlete making a high jump, it is very important to have the optimal sequence of steps, the stride length, ie the combination of steps, determined. The best offset combination is realized with a device that uses two types of wavelength light sources 4 on a blue rubber-plastic surface (red light) and an oblique outer path (green light) is equipped. This is done by a single LSBF system with two different light sources 4 reached.

Example 2: Use of the invention to promote football training

For 3 Attacker - 3 Defender situation exercises we build a system that creates, projects and moves a group of shapes from 3 to 3 different beam shapes drawn in two different colors on the lawn of the fields are. These are supposed to be six LSBF systems in the projector 15 which form two groups of three different colors. So that each athlete can follow each direction of movement, ie the projected plurality of (six) beams of light 7 does not cover, a coordinated projection system is placed on two opposite sides of the current playing field.

Example 3: Use of the present invention to promote handball training

For the training of a defensive formation, five one-man athletes should be closely moved between the six and nine lines. At this point, five simultaneously projected light rays of the same color are provided on the bottom plate, whose shape is different: circle, triangle, square, cross and pentagon. Accordingly, in this case, five pieces of LSBF systems will be in the projection unit 15 implemented.

Example 4: Use of the present invention to promote motorcycle training

In order to achieve the fastest lap time, it is very important to follow closely the best curves of the curves with the maximum but safe speed. Each of these sheets is determined in advance and then to the ground unit control computer 14 which converts this data into track coordinates and speed values. The projection unit 15 projects and moves a clearly visible light signal on the asphalt, followed by the competitor.

The device according to the invention promotes the development of athletes and teams in various sports by projecting the locomotion movements expected by the athlete directly by means of light, with the aid of light on the sports-specific terrain. The projection of these movements is done using data from previously captured imagers or by recording data from analysis software from the positioning of GPS devices recorded on the athlete being tracked. The device according to the invention is also suitable for projecting a predetermined and executed movement by the trainer. It is also possible to track the motion of the sphere (e.g., with built-in GPS encoder data) and the subsequent simulation. The device according to the invention can also be used for recreational purposes.
