COMPETITIVE SITUATIONS

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

The state of the art is described below. In competitive sports, the training sessions prepare the contestant for the race. An athlete can only make the best of his performances in races or matches if in the training sessions they are subjected to heavy loads on a regular basis even only for a part of a task, or encounter situations of decision like the ones in real competition. Reconstruction and implementation of the competition load and competition situations on training sessions has been almost an impossible task for athletes and coaches so far. The device we have developed is technically closest to devices used for the production of laser shows and to laser projectors, so we look closely at their relevant features below.

Laser show. In this case, a different pattern with a fast, controlled movement of a single laser beam can be drawn. The point here is that the single point of the laser in the device moves at a rate that unifies into a continuous curve of points for the human eye in different spatial locations, creating a picture of a coherent shape in the brain. Due to the technique used, for most of the time, only contours are drawn, to achieve a superficial pattern much faster movement, "satirization" is required. The desired light effect is usually solved by a dual mirror galvo engine controlled by a computer software. This allows the controlled deviation of the laser beam in the x-y direction, i.e., the drawing of the forms provided by the controller computer. The equipment itself is quite simple and does not usually include any other serious optical system. Such technical solutions are described, for example, in the following Internet resources, where the download date is the date of priority of this patent application:

To achieve more spectacular patterns, not only one laser of a particular color is used, but also up to 34 kinds of colours, each of which is bent separately. Examples of such solutions include the following resources:http://www.lh-laser.com/views.asp?hw id=358.

In order to see the shapes drawn by this method in large dimensions for large number of viewers, relatively high performance lasers (> 500 mW) are used as light sources. Since this performance is emitted in a few millimeter spots, this is why the surface light intensity density is great at given location, which can have a serious health-damaging effect when it reaches the human eye. Laser Projector. The main element of a typical laser projector is the laser operating on three different wavelengths, namely the R, G, B base colors (red, green and blue). For the necessary color mixing, the three laser beam should be merged into a single parallel beam. A white light beam is normally created. 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 controlled in some way independently of each other, to bring it in line with the image content to be displayed. The combined beam and the color of the pixel generated by it on the projection surface can be changed from moment to moment by precisely adjusting the RGB ratios, by mixing the base colors with the appropriate intensity. This control matches the visual parameter data for the image to be projected. The blend beam formed from the three laser beams must be moved by the parameters corresponding to the known imaging standards so that the pixel created by it "scans" the projection surface. In the case of laser projectors, we cannot mention strictly speaking projection, since the image is not screened in one piece, at one time, and said image is not imaged, as when using conventional projectors, but it is drawn by the very rapid movement of a single point of light produced by the blend beam directly on the projection surface. This means that the beam should be diverted by a moving system in x-y direction, drawing that frame from row to row, column to column. For example, see US patent document US7756174.

Thus, the main steps of the imaging process are as follows: 1) digitizing the projected analog picture signal with the control unit, and then guiding it to an intermediate storage. 2) Next, color transformation takes place, which ensures color compatibility between the color space of the RGB lasers and the the TV/video system. The transformed RGB data is led to the laser modulator, where they are converted into optical information by means of intensity modulation by R, G, B channels. 3) Then the proper pixel deflection, the projection may take place. For horizontal deflection often a rotating polygon mirror is used at 1300/s round number. This is followed by a galvanometer mirror movement system that performs vertical deflection. To move said galvanometer mirror, such galvano motors are used, as disclosed in US8031386 patent document.

In the last few years, the beam moving technique has been further developed. With a simple plain mirror, the blend beam is projected onto a "two axis" MEMS (Micro Electro-Mechanical Systems) scanning mirror that performs the laser beam optic diversion. This integrated electromechanical-optical device, more precisely, the mirror inside it can also have a fine, controlled motion around the vertical and horizontal axes. Such a solution is disclosed in e.g. US8638446 patent document.

The projected laser beam emits directly from the MEMS scanning device and it creates the image in front of the projector on any surface that the beam reaches. The output radius is just as divergent that the increase in the image size is followed by the increase in pixel size. The result is a sharp picture at any distance.

That is, as long as the image projected by the laser projectors is roughly sharp everywhere, the sharpness of the traditional projector must be permanently adjusted after the projection distance changes, and parts of the image will be blurred, when projected onto a surface that is not evenly spaced from the device. Such can be for example a flat surface, when the orientation of the projection is not exactly perpendicular, but such is an arbitrary three-dimensional surface as well.

US4588887 patent document discloses a device for optical reproduction, wherein the light source is a laser diode (ILD, Injection Laser Diode), the path of the laser light from which it is first broken by a fixed mirror and then by a galvanometer mirror rotatable along a longitudinal axis, the moving of said rotatable mirror being implemented by a vibration galvanometer (resonant galvanometer). US4762994 patent document discloses an optical scanner, in which the light source is a laser and where the laser light path is broken by a scanning mirror. The oscillating movement of the scanning mirror is also solved with vibration galvanometer in this case. A similar system is disclosed in US20050128553 patent document, whereby the disclosed system is used, for example, to produce printed circuits.

US6344917 patent document discloses a galvano mirror assembly which can be used use in an optical disc drive, wherein the direction of the laser light is changed by the aforementioned galvanometer mirror.

We do not know about the sports application of projected dynamic directional lights. In industrial manufacturing technologies, a layout for practicing assembly steps is already in use, where, for example, a traditional video projector placed above a desktop, projects the textual and graphical information required during the learning process.

For the purposes of sports use, reference should be made to HU222643 B 1 patent document (Equipment for facilitating training and practicing of ball games), which describes the operation and applicability of a device, in which light signals are used to promote ball games. The equipment is based on a rigid frame and light transmitting ball keeping exercise board targetable by ball players. The exercise board consists of several individually illuminated fields, behind which there is a segmented light source. The main goal of the training is to practice the target throwing, kicking, and fixing the necessary moves, dynamically, and kinematic parameters. By illuminating the area according to the coach's concept, the field in the board is assigned to the practicing player, that is to be targeted, and the athlete tries to deliver the ball to this point. The referenced patent and the device we have invented design are only common in that both are used for training purposes and use of light signals. Independently, both the illuminated area (full sports track vs. multi-segment exercise board) and the type of illumination (mirror-based scanning with LED or laser illumination vs. fixed, segment lighting), as well as specific use (determining the movement direction of players vs. targeting area to be scored) are different from each other.

The technical problem to be solved with the invention is to ensure that an athlete at the trainings can not only get theoretical instruction in the athlete's expected locomotor sporting movements but also, during a reconstructed or simulated race situation, they can see and execute the required locomotor movements in practice, thereby achieving precise control of the athlete. The technical problem to be solved with the invention is also to ensure that it be possible to precisely instruct multiple athletes to move together simultaneously at trainings.

The foregoing objects are achieved by the present invention by means of a discovery based on the fact that competition situations may be reconstructed or simulated by an optical device designed to project direction spotlights of various geometry and/or color onto the surface of a sports field and to move them in a predetermined manner in a given direction and at a given velocity. The aforementioned optical system allows more precise control of the simultaneous movement of several athletes simultaneously.

9. The device according to Points 1 to 7, wherein the projector unit 15 is located on the holder of lamps illuminating the field, mounted on its own stand, fixed to the ceiling in the case of a gymnasium or is placed on a stable, well-controlled spatial position drone. We have developed a new device for the production of spotlights that enable the dynamic reconstruction of competitive conditions that can achieve sufficiently high level of lightness, pattern, and change velocity at a particular sport ground surface in the required illumination shape. The invention will be further described with reference to the accompanying drawings.

Figure 1 shows a block diagram of the main parts of an embodiment of our developed apparatus. The apparatus includes a ground unit 14 located at the location of the application site, for example on the edge of a field, available for the trainer, a helper; while the other element, the projector unit 15, which is located above the sports field, raceway, at 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 fixed, for example, to the holders of the illuminating lamps, to their own stand, to the ceiling in case of a gymnasium, or to other fixing elements. An additional fixing solution is when the projector unit 15 is installed on a well-controlled spatial position drone, resulting in a much more flexible device. The projector unit 15 comprises a radio frequency receiver unit la, a control unit lb, and 21, 22, 23 ... 2n light source - beam forming optical - scanning unit systems, wherein said light source - beam forming optical - scanning unit systems 21, 22, 23 ... 2n comprise one or more 4 light sources, a mechanically coupled 3 beam forming optical unit, and 2 scanning units.

The ground unit 14 includes a control computer 6 and a radio frequency transmitter unit 5. The position data database to be projected should be fed to the control computer 6, said position data database is converted by software for the projection unit 15. Depending on the training task, the database can be purchased or can be made using the GPS coordinates of our own athlete(s). The computer program then converts the input data, whereby the projecting unit 15 projects the corresponding pattern to the appropriate location and moves it at the desired speed in the specified direction. Here, therefore, three tasks must be solved simultaneously. First, we need to create a user interface that allows the trainer to enter the desired combination of motion and to translate it into exact physical, geometric data (spatial positions, speeds, directions, etc.) and then to send instructions to the projector unit 15, which then will realize these 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 the purposes of the present invention, examples of the control computer 6 include, but are not limited to, personal computers, laptops, notebooks, and tablets.

The RF receiver unit la in the projection unit 15 receives signals from the ground unit 14 and transmits it to its own control unit lb. Based on the instructions, this equipment controls the projecting. This control unit lb sets 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 light source - beam forming optical - scanning unit system. The said light source - beam forming optical - scanning unit system comprises light sources 4, beam forming optical units 3, and scanning units 2. The number of such light source beam shaping optical scanning units incorporated in a particular projector 15 can be increased according to the user's needs and the requirements of the specific task. The power supply of the unit can be solved by means of electric network source or batteries. In the case of drone installation, only battery may be used, while in a fixed rack the network power supply can be secured safely.

One or more of the light sources 4 used must meet the following essential, basic requirements during the illumination. 1. The light pattern created on the ground must be visible to the athletes participating in the training session. To achieve this, it is necessary to produce a sufficiently high intensity and, on the other hand, to produce an appropriate illumination wavelength corresponding to the optical properties of the given ground surface. Proper selection of these two parameters belongs to the knowledge of the person skilled in the art. It makes difference, if a grassy area has to be clearly visible, or on a parquet, asphalt, plastic, rubber, etc. on paved ground.

2. Care is to be taken to ensure that the one or more light beams 7 applied do not present any danger to the athletes, coaches, observers, spectators eyes, physical integrity. According to our preliminary studies, a spotlight of about 10 cm in diameter dimension with given from would be well-recognized and traced on the field. For this task, relatively low power (a couple of times 100 mW) lasers and the recently more dynamically developing, high-performance (few Watts) LED light sources would be best suited together with their power supply. Our preliminary experiments showed that 3-4 colors (red, yellow, green, possibly blue) cover all commonly used cover types. Accordingly, without being limited to these, two types of apparatus are disclosed as preferred embodiments. In one, only kind of one or more light sources 4 with wavelengths for one user-defined size are incorporated, while the other one has two or more light sources 4 that are illuminated in two or more colors, so that the device can be universally applied to all types of cover types. By the use of three color components (red, green and blue, RGB) light sources 4, which for example, but without limitation, can be either a laser or a LED, in theory any color can be blurred, but the light scattering ability of the surface to be illuminated must be taken into account in the wavelengths of the base colors. In order that the system be able to adapt to the current lighting conditions and light scattering properties of the ground, one or more light sources 4 must be of controllable performance. With such a complex equipment, it becomes possible to project multiple color-coded information.

The beam forming optical unit 3 is illustrated with reference to Figures 2 and 3. One or more light sources 4 are provided with optical elements [lenses, mirrors, apertures/masks, optionally programmable spatial light modulators (SLMs) etc.] to complete the required tasks and to provide the required projected one or more shapes. The first element of one or more of the beam forming optical units 3 is the beam deflection optic 8a. Its task is to convert the light beam 7 emitted from the light source 4 to the appropriate size, diameter, thereby enabling the proper area of the aperture plate or spatial light modulator (not shown in Figures 2 and 3) responsible for the formation of the given beam shape be completely illuminated, but do not lose more light intensity.

As illustrated in Figs. 3 and 4, in the second step, light beam 7 expanded to the appropriate size illuminates the beam forming unit 8b (not shown in FIG. 4), which in the embodiment shown in Fig. 4 is an aperture plate 10 equipped with holes of various shape, which is rotated by an electric motor controlled by a control unit lb (not shown in Fig. 4), thereby produces the desired pattern can be projected. In a further embodiment, the beam forming unit 8b (not shown in FIG. 4) is a spatial light modulator 13, in which the appropriate beam pattern can be generated by the pixels (opaque pixels: 11; transparent pixels: 12) that can be switched on and off (variable throughput) by control unit lb (not shown in FIG. 4). By means of the aforementioned elements, it is possible to realize that, with the use of a light source - beam forming optical - scanning unit corresponding to the number of athletes to be controlled, each athlete has different beam shape. For the purposes of the present invention, the terms "beam forming unit" and "aperture" are used interchangeably.

For example, but without limitation, the shape created by the beam forming unit 8b may, be projected into the ground by the following two methods.

i) In an embodiment of the device according to the invention, the simplest solution is using a sufficiently small, so called collimated light (Figure 2), when the beam shape leaving the aperture illuminates the field. The size of the projected shape can be influenced by the divergence (distortion) and the projection distance of the light beam 7 that can be set under certain limits, and the projection location is determined by the scanning unit 2. ii) In a further embodiment of the device according to the invention, there are fewer requirements (such as collimability) for one or more light sources 4, when the (even divergent) beams of the beam forming unit 8b pass through an imaging lens 9 to reach the scanning unit 2 (Figure 3). In this case, the image of the aperture is projected with optical imaging, the size of the image is affected by the angle-magnification of the optical system and the projection distance, and the exact location of the projection is also determined by the scanning unit 2.

The task of the scanning unit 2 is to move the light beam 7 passed through the shaping unit 8b with the desired parameters, to project said light beam to the surface of the ground. In a preferred embodiment of the invention, the scanning unit 2 is a commercially available mirror scanner. The said mirror scanner comprises two highly reflective mirrors at the applied wavelengths, which are fixed to galvo motors according to the conventional scan geometry. The size of the mirrors is determined by the applied beam forming unit 8b and, optionally, by the imaging optics 9, the galvo engine speeds and positioning accuracy are largely in line with the requirements of our equipment. The position and movement of the two motors, and thus the mirrors on them, are adjusted by the control unit lb belonging to the projector 15 according to the current task.

From all of the components described above, the apparatus constructed in the described manner differs from the training aids used so far. Its high flexibility makes it unique in this area. It is possible to project static and dynamic patterns, and the shapes of the directional lights used can also be changed during the workout. The high precision adjustment of the scanning unit makes it possible to make any point of the field covered by the training available by sufficiently precise localization and dynamics (there is no need to divide and segment the field area into a given number of cells). The number of players involved in training can be expanded easily by switching on new units. Displaying the desired shapes on a field does not require changing the surface of the surface of the field, this will be discussed later.

The device according to the present invention can simulate, even on international level games and competitions, better than in any technology that supports the training so far.

The device according to the present invention provides a more direct and accurate signal or signals to one or more athletes as compared to the state of the art about the expected locomotion movements, no matter how complex they are, thus opening new horizons to the athletes and team development and analytical possibilities. These locomotive movements can be directly displayed to the athlete: whether it is a tournament or a match situation, or a complete tournament or match, or even a previous athlete's move or other athlete's movement, and even the ball path in ball games. An embodiment of the present invention provides simultaneously the projection of a plurality of sportsmen, team members, whole teams or even more teams. The projecting is done using geometric figures in two dimensions from the top to the ground, covering the particular sport. The athletes' task is to follow the change in the location of the geometric patterns around them. Athletes are immediately able to perceive the movements they expect, their direction, speed, rhythm, and perceive the difference between their own and their expected movements in real time in a competitive situation, in the same space as the match. As desired, either in real-time or in the initial phase of the exercise, any movement that is required can be seen by athletes even slowed or accelerated at any speed as desired.

Using the device according to the invention, unlike in case of the techniques known in the prior art, the athlete, not only in theory receives instructions, but also sees them directly in practice during simulated competition situation. This gives an opportunity for almost immediate correction and even more efficient workouts.

By means of the valuable, high-quality workouts in simulated racing situations, an increase in the 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 mechanism, their creativity of the athletes and teams, their cognitive abilities and their cooperation can be developed effectively.

With simulated competition situations, new tactical and individual solutions, team-based solutions, and more thoughtful versions of them can be practiced, or even previously misaligned situations can be projected, thus finding the right solutions and practicing them. The practiced variations are added to the team's tactical repertoire and the athlete's game intelligence develops.

The projecting can be stopped at any point in time, after which the athlete must choose a creative solution for the particular competition situation, at individual training, tactical training or team sport to develop the teamwork. By stopping the projection in a simulated competitive environment, using the device according to the present invention, the athlete will be put into a decision-making situation, and with independent solutions, the creativity, the speed of the decision-making mechanism, efficiency and in case of a team play, the cooperation can be greatly improved. The evaluation of the performance shown provides a broad range of analytical opportunities for the coaching staff, thus enabling the development of athletes.

The device according to the invention provides improved performance of the workout compared to the prior art, thereby achieving faster and more spectacular results.

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

In football, match load can not be reconstructed with buoys, with arms, either team or part-team level, or individually. No striker or defender movement can be reconstructed with pickets or buoys, even for a simpler attack, as it would model a static state and would lack the correct speed of movement, rhythm, timing, and the angle of directional changes. Since football is not a cyclical sport and contains extremely complex movements, it makes it even more difficult to reconstruct match situations, competition situations, competition loads, and decision situations that can be accurately simulated by an embodiment of the present invention.

According to one embodiment of the invention, it is a significant innovation in promoting football training that it can provide new impulse to the players on a daily basis or even to sub -tasks, even to reach the level of international matches, which is indispensable for development and the preservation of competition shape. Quite often this is not possible for athletes to gain access to the training during the team play, because they know each other's abilities, patterns and they are doing the same workout.

Another limitation factor may be that the players have a similar level of fitness within a team. Although differences in fitness levels may occur between individuals depending on certain genetic conditions, current shape, different motivation levels, and other factors, they cannot influence the overall fitness level of a whole team. If some athletes still have some ability to influence the whole team's fitness level, that can already be considered as the overall level of fitness for the whole team. The impact of the performance of few players on a whole team can not be effective enough for the development of the team and is sufficiently effective, for example, because they do the same workout, they know each other's abilities, patterns of movement, and because the players who are showing better performance are always limited by the weaker performance of their teammates. As teammates unintentionally limit each other's development, they need a new impulse, a realistic match-load - even just for sub-tasks - and decision-making situations for development. It is a good example in the workout in one-on-one game, in one fight the race between two genetically different players. If the quicker player is to be able to dismount the other player within 10 meters, then he will not overtake it by 3 meters, then turn back and make more distance in sprint because it would not be reasonable in that match fight. However, the slower player limits the development of his teammate, as he does not force his companion to an intensity and length of sprint (not to mention rhythm, angle of change of direction, and many other important factors); to which, however, e.g. in a match situation the opponent's faster player will. A similar problem exists, for example, in the case of differences in knowledge or motivation, or differences in ability. As a result, a player with a better ability is not forced to get the maximum out of his workout being limited by his partner's weaker performance. Because of this, he can not develop properly, can not achieve his genetically determined maximum performance, his development can stagnate, his performance and competitive form may deteriorate.

According to one embodiment of the invention, for physical development purposes, even complete international matches or half-time can be projected, which players have to track per position. This not only can improve, but it can even measure the physical strength of individuals or even the entire team. It can be added to the daily routine even for part-tasks.

According to an embodiment of the invention, it is possible to present an action, sequence, or run of an elite player, in the framework of an individual training, either from an international match, thereby providing the required impulse to the player on the workout.

The projected motion can be plucked by either a defender or a striker either individually or even in pairs, even with 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 performed as a ball exercise. This task will help us to locate, where exactly the elite player has assumed the rank, how fast was he, and in a rhythm he made, how much distance he had from the opponent in the match fight, and what angle he changed the direction and how he started the sequence at the end of the movement line, further assisting this developmental learning process. Initially, any movement can freely be slowed, then even in real-time or accelerated, it can also be projected. The projection may be stopped at any given moment to make the player stand in decision situations and let him choose the right solution, thereby developing the creativity, the speed and efficiency of the decision mechanism. Choosing the right solutions in decision situations and their improved versions, new variations of pre-edited and projected solutions to fix previous errors will improve game intelligence and individual capabilities.

According to an embodiment of the present invention, it is possible to prepare the current upcoming opponents even by projecting their movements.

According to a further embodiment of the present invention, not only the predetermined competition positions can be projected, but also the simulation of fictitious, pre-constructed situations. The apparatus according to the invention also provides many new applications in the field of tactical training and the development of team work. So long as tactical instructions could only be given to players on a board, tablet, or verbally in the football field (as the team's movement could not be otherwise demonstrated), they can now be shown in practice on the playing field.

The apparatus according to the invention provides a more precise control of the combined movement of several players at a time, which has so far been only superficially discussed, who and how will move to practice a tactic, and if it was intended to show exactly who and where to move, the coach could only instruct a single one player or at the same time a few players. Simulating realistic match situations while training, while practicing tactics is even harder. With the apparatus according to the invention, controlling, instructing and moving complete parts of a team, or the whole team or even multiple teams in real time can be accomplished, by slowing down or even accelerating.

The apparatus according to the invention also provides the possibility of stopping the projecting at any given moment, thus placing the players in decision situations and allowing them to choose the appropriate solution independently, thereby developing their creativity, speed and efficiency of decision making, outstandingly thus contributing to the development of the interplay. By practicing the improved solutions that are chosen in the decision situations and their revised versions, as well as the pre-edited and projected new tactical variations, and the solutions found to correct previous mistakes, the team's tactical repertoire is expanded and its team play develops.

The apparatus of the invention provides a lifelike simulation of match situations, whether the situations are previous mistakes to be corrected, predefined movements, or movements of other teams. For example, the ball carrying out of an elite team can projected, passing of the ball, or a counter-attack after losing the ball, or how an offensive team breaks down the other team's defense in an international match. It can be shown how an elite team that attacks, shifts in certain situations: how fast, in which part of the field, in what kind of position, in what form, and how far apart are the players.

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

The apparatus of the invention provides an accurate picture of the choice of other professional athletes in certain play situations, of the movements chosen in view of the tactics and the interaction, and of how an elite player moves throughout the course of the whole match in the territory of the field.

The apparatus of the present invention also provides an opportunity for analyzing the current opponent. It is also possible to analyze some of the strategically important attacks of the opponent by practicing the defense against them, or projecting the mistakes in defense and practicing how to exploit them. Players can already experience the opponent's movements, sense their speed, rhythm and direction at the training making it easy to prepare for the match, helping the team achieve victory and success.

The invention allows for the use for facilitating athletic trainings.

The invention allows for projecting the athlete's predetermined run, or runs at previous competitions, or runs of another athlete on the runway, in the course of an athletic training, thus simulating the competition. The projection can be used to determine the desired speed and rhythm of running, thereby building a strategy of the athlete's running in a tournament or workout, or analyzing a previous run of another athlete or physically developing that athlete.

The invention allows a particular athlete to perform certain distances within certain seconds in the course of a given workout, or even several times in succession, even by slowing the running of a previous personal best of that athlete to the desired extent depending on which stage of preparation is performed, and what they want to develop.

The invention provides a projection for development, practice, analysis, so that the 400 meter run race of an elite athlete is performed, i.e. the speed of certain part of the run is simulated.

The invention provides a projection of the personal best of the athlete's jump or of another athlete's jump in the course of a high jump workout.

Below, the use of the apparatus according to the invention is mentioned in some other sports, without limiting the invention. The invention should be applied by simulating competition situations, complete competitions, for the purpose of development, analysis, taking into account the characteristics and features of the sports.

The invention provides an application for promoting American football workouts.

American football is much shorter in comparison to European football, and the attack is set off more often from fixed positions, when players have the opportunity to take their positions in advance. Therefore, tactics may be even more important. As the game consists of short sections, it can be built more accurately, attacking and defending can be practiced. Players use dozens of pre-practiced tactical variations. Their training, analysis and development are significantly more efficient and more efficient with the help of the equipment of the invention.

The invention makes it possible to use rugby trainings.

The invention provides an application for promoting car and motor sports trainings.

The invention allows the design of an ideal curve on the track in front of the racer, preferably predetermining the degree of acceleration and deceleration and its location and the maximum speed that can be safely taken for that particular curve.

The invention provides an application for facilitating the training of younger racing athletes.

All of the advantages of the invention described in greater detail receives great importance in the course of younger athlete's trainings. For younger racing athletes, the specific goal to be achieved, the level to which they need to adapt physically and mentally later becomes visible.

The invention allows for the use of recreational sports activities.

The present invention allows for the use of recreational use by non-competitive athletes, even as far as necessary, slowing the projection. Wide masses can be addressed and involved in the world of motion and sport, whether they are children or adults. The programs of general and secondary schools, colleges, leisure centers, sports complexes, hotels, and adventure parks can, for example, be real-time or slow-motion project a real, legendary match, in which participants can test their physical abilities, tactical skills and gain real enjoyment, to become part of a famous game, and feel as if they play with a world class athlete.

By means of the invention, it is possible to directly simulate competition situations and complete competitions directly by projecting the motion of one or more athletes in practice. In this way, the athletes' individual abilities, the physical condition of the athletes and teams, their strategic, tactical preparedness, their combined movement, their thinking, the efficiency and speed of their decision-making mechanism, their creativity, their cognitive abilities, their game intelligence and the interaction can be improved. Athletes are immediately able to perceive the movements they are expected, their direction, speed, rhythm, and perceive the difference between their own and their expected movements in real time in a competitive situation, in the same space as the match. As desired, either in real-time or in the initial phase of the exercise, any movement that is required by athletes can be seen, even by slowing or accelerating said movement at any speed.

Using the apparatus according to the invention, in contrast with the prior art, the athlete does not just get the instructions from the locomotion movements expected in theory, but he also sees them directly in practice during simulated racing. This gives us the opportunity for the almost instant correction and even more efficient workouts.

The projection can be stopped at any point in time, after which the athlete chooses a creative solution for the particular competition situation individually, in order for a tactical training or teamwork to develop a team. With the help of the present innovation, in a simulated competitive situation, by stopping the projection, the athlete gets into decision-making situations, and with the individual solutions given to them, creativity, decision- making mechanism speed, efficiency and team play can be greatly improved.

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

Displaying, projecting a given pattern to the field does not require, for example, transparent coverings, no substructure (structural elements under the ground) is required. All this is important because the changed physical parameters can affect the athletes' performance, muscle, endurance and reversal technique, and their development within realistic circumstances. For example, it has an entirely different effect on athlete's muscles, joints, and skeleton when running on asphalt cladding or on grassy ground. On the other hand, replacement and modification of the coverings would have a significant additional cost. Another advantage of the system is that it can be applied in snow, dirt, and mud.

The apparatus according to the invention can be used to detect, correct errors, analyze any situation, and the performance of an athlete or the opponent. By practicing some of the elements and their improved versions, the strategic, tactical repertoire can be expanded. In a never-seen way, it is possible to control the combined movement of several athletes. The evaluation of the performance shown provides a broad range of analytical opportunities for the coaching staff, thus enabling the development of athletes. It raises your training to a new level, achieving fast and spectacular results.

In order to be the best performer in the athlete's competition, they have to be in a training session in competitive situations, competitive burdens, decision situations and need new impulses for development and the preservation of competition shape. The present invention provides this assistance and, through versatile simulation of competitive situations, the efficiency of training can be increased to unprecedented levels, opening new horizons for the development of athletes and teams to help them achieve success.

In the following, the invention is illustrated by means of exemplifying examples which are not intended to be construed as limiting the invention. EXAMPLES

Example 1 : Use of the present invention to aid high jump workouts

For the athlete performing high jump, it is very important to have the optimum step sequence, step length, i.e. step combination established. The best offset combination is implemented with a device equipped with two types of wavelength light sources 4 on a blue rubber-plastic surface (red light) and an outdoor sloping path (green light). This is accomplished by a single LSBF system using two different light sources 4.

Example 2: Use of the invention for promoting football training

For 3 attackers - 3 defender situation exercises, we build a system that produces, projects and moves a group of shapes of 3 to 3 different beam shapes drawn in two different colors in the fields's lawn. To do this, six LSBF systems are to be incorporated into the projector 15, forming two groups of three different colors. In order that each athlete be able to follow any direction of movement, i.e. not to cover the projected plurality of (six) light beams 7, a coordinated projection system is placed on two opposing sides of the current playing field.

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

For training a defensive formation, five single-team athletes should be moved closely aligned between the six and nine lines. At this point, five simultaneously projected light beams of the same color are provided on the ground cover, the shape of which is different: circle, triangle, square, cross and pentagonal. Accordingly, in this case, five pieces of LSBF systems are implemented in the projection unit 15.

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

To reach the fastest lap time, it is very important to closely follow the best curves of the corners with the maximum, but at a safe speed. Each such arc is determined in advance and then fed to the controller computer of the earth unit 14 which converts these data into track coordinates and speed values. The projecting unit 15 projects and moves a clearly visible light signal on the asphalt followed by the competitor.

The apparatus according to the invention promotes the development of athletes and teams in different sports by directly projecting the locomotion movements expected from the athlete by means of light, by means of light on covering of the sport specific ground. Projection of these movements takes place using data from previously captured imaging equipment or by recording data from analytical software from the positioning of GPS encoders recorded on athletes to be tracked. The apparatus according to the invention is further suitable for projecting a predetermined and engineered motion by the trainer. It is also possible to track the movement of the ball (e.g. with built-in GPS encoder data) and subsequent simulation. The apparatus according to the invention may also be used for recreational purposes.
