Description

Optical device for dynamically reconstructing or simulating a competition situation

Technical Field

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

Background

The prior art is as follows. In athletic activities, a training program prepares players for an event. Athletes can only achieve their best performance at or during an event or competition if they are often heavily loaded during a training program, even if only for part of their mission, or when they encounter decision-making situations such as in a real competition. To date, the reconstruction and implementation of the racing load and the racing situation of a training program is a task that is nearly impossible for athletes and trainers to accomplish. The devices we have developed are technically closest to the devices and laser projectors used to make laser shows, so we will next carefully investigate their relevant features.

And (6) performing by laser. In this case, different patterns with fast, controlled motion of a single laser beam can be drawn. The point here is that a single point of the laser in the device moves at different spatial positions at the rate of a continuous curve that is uniform as a point to the human eye, forming a coherent shaped picture in the brain. Due to the technology used, for most of the time, only contouring to achieve faster action of the surface pattern requires "detraction". The desired light effect is typically addressed by a two-mirror galvanometer motor (mirrorgalvo engine) controlled by computer software. This allows for controlled deviation of the laser beam in the x-y direction, i.e. the drawing of a table provided by the controller computer. The device itself is quite simple and does not normally include any other important optical system. Such a solution is described, for example, in the following internet sources, where the download date is the priority date of the present patent application:

in order to allow a large number of viewers to see the shapes that are drawn on a large scale by this method, relatively high performance lasers (. gtoreq.500 mW) are used as light sources. Since this property is emitted in a spot of a few millimeters, which is why the surface intensity density is large at a given location, it has a serious health-damaging effect when it reaches the human eye.

A laser projector. The main components of a typical laser projector are lasers of three different wavelengths, namely the R, G, B primary colors (red, green, and blue). To perform the necessary color mixing, the three laser beams should be combined into one parallel beam. A white light beam is typically produced. In order to achieve a guaranteed color effect on the screen surface, the light intensities emitted by the three lasers have to be modulated and controlled in a manner independent of each other so that they coincide with the image content to be displayed. By fine tuning the RGB ratio, the color of the combined beam and its resulting pixel on the projection surface can be changed at any time by mixing the primary colors with the appropriate intensities. This control is matched to the visual parameter data of the image to be projected. The mixed beam formed by the three laser beams must be moved according to parameters corresponding to known imaging standards in order for the pixels it produces to "scan" the projection surface. In the case of laser projectors, we cannot project strictly speaking, since the images are not projected one at a time as with conventional projectors, but are rendered by very rapid movement of the single spot produced by the mixed beam directly on the projection surface. This means that the beam should be steered in the x-y direction by the moving system, drawing pictures from one row to another and from one column to another. See, for example, US 7756174.

The main steps of the imaging process are therefore as follows: 1) the projected analog picture signal is digitized by the control unit and then directed to an intermediate memory. 2) Next, a color conversion is performed, which ensures color compatibility between the color space of the RGB laser and the TV/video system. The converted RGB data is directed to a laser modulator where it is converted to optical information by intensity modulation of the R, G, B channel. 3) Appropriate pixel deflection, projection, can then be performed. For horizontal deflection, a rotating polygonal mirror (polygon mirror) is generally used at 1300 revolutions per second. Then a galvanometer mirror moving system that performs vertical deflection. For moving the galvanometer mirror a galvanometer motor as disclosed in US8031386 patent document is used.

In recent years, beam shifting techniques have been further developed. The mixed beam is projected with a simple flat mirror onto a "dual-axis" micro-electro-mechanical system (MEMS) scanning mirror that performs the light steering of the laser beam. Such an integrated electro-mechanical-optical device, more precisely the mirror inside it, can also perform fine, controlled movements around the vertical and horizontal axes. Such a solution is disclosed, for example, in US patent 8638446.

The projected laser beam is emitted directly from the MEMS scanning device and creates an image on any surface that the beam reaches in front of the projector. The output radius is divergent as the pixel size increases with increasing image size. The result is a sharp picture at any distance.

That is, if the image projected by the laser projector is roughly sharp anywhere, the sharpness of the conventional projector must be permanently adjusted after the projection distance is changed, and a partial image will be blurred when projected onto a surface having an uneven distance from the apparatus. For example, such a surface may be a plane when the projection direction is not exactly perpendicular, but such a surface may also be an arbitrary three-dimensional surface.

US 45887 discloses an apparatus for optical replication in which the light source is a laser diode (ILD, injection laser diode), the optical path of the laser light from the laser diode being interrupted first by a fixed mirror and then by a galvanometer mirror rotatable along the longitudinal axis, the movement of the rotatable mirror being effected by a vibrating galvanometer (resonant galvanometer).

The US4762994 patent document discloses an optical scanner in which the light source is a laser and the laser light path is interrupted by a scanning mirror. In this case, the oscillating action of the scanning mirror is also solved using an oscillating galvanometer. A similar system is disclosed in US20050128553, where the disclosed system is used for example for producing printed circuits.

US6344917 patent document discloses a galvanometer-mirror assembly usable in an optical disc drive, wherein the direction of the laser light is changed by the above-mentioned galvanometer-mirror.

We do not know about sports applications of projecting dynamic directional lamps. In industrial manufacturing technology, text and graphical information required during the learning process has been projected using designs for practicing assembly steps, such as a conventional video projector placed above a desktop.

For the purpose of sports use, reference should be made to the HU 222643B 1 patent document "device for facilitating training and practice of ball games", which describes the operation and suitability of a device for facilitating ball games using light signals. The device is based on a rigid frame and a light-transmitting ball that allows the player to aim at the board. The board consists of several individually illuminated areas followed by a segmented light source. The main goals of the training are to practice target throwing, kicking, and to dynamically fix the necessary position variations and kinematic parameters. The area in the board to be aimed at is assigned to the practicing player by illuminating the area according to the coach's mind, and the player tries to pass the ball to that point. The cited patents and the device of our invention are the same only in that both are used for training purposes and use of optical signals. The illuminated areas (complete sports track vs. multi-segment practice board) and the type of lighting (mirror-based scanning using LED or laser lighting vs. fixed segment lighting), and the specific use (determining the direction of movement of the athlete vs. aiming the area to be scored) are different from each other, respectively.

The technical problem to be solved by the invention is to ensure that the athlete in training not only can obtain theoretical guidance in the athletic sports actions expected by the athlete, but also can see and execute the required sports actions in practice during the reconstructed or simulated event situation, thereby realizing the accurate control of the athlete. The technical problem to be solved by the invention is to ensure that a plurality of athletes can be accurately guided to move together at the same time in training.

The present invention achieves the above object by finding out based on the following facts: the competition scenario can be reconstructed or simulated by an optical device designed to project directional spotlights of various geometries and/or colors onto the surface of the playing field and to move them in a predetermined manner in a given direction and at a given speed. The optical system described above allows more precise control of the simultaneous movements of several athletes at the same time.

We have developed a new device for producing spotlights that enables dynamic reconstruction of race conditions, allowing sufficiently high brightness, patterns and variation speed to be achieved with the required illumination shape on a specific moving ground. The invention will be further described with reference to the accompanying drawings.

Figure 1 shows a block diagram of the main components of an embodiment of the apparatus we have developed. The apparatus includes a ground unit 14, which is located at a point of use location, such as on the edge of a field, available to trainers, assistants; and the other element, the projector unit 15, is located at a known height above the playing field, runway. The position of the projector unit 15 is determined by the task to be performed and the position geometry. For example, they may be fixed to a bracket of a lighting fixture, to its own bracket, to a ceiling in the case of a gym, or to other fixed elements. An additional fixing solution is to form a more flexible device when the projector unit 15 is mounted on a well-controlled spatial position drone. 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 system, wherein the light source-beam forming optical- scanning unit system 21, 22, 23 … 2n comprises one or more 4 light sources, mechanically coupled 3 beam forming optical units and 2 scanning units.

The ground unit 14 comprises a control computer 6 and a radio frequency transmitter unit 5. The position data database to be projected, which is converted by the software for the projection unit 15, is input to the control computer 6. Depending on the training task, databases may be purchased or may be created using the GPS coordinates of our own athlete. The computer program then converts the input data, whereby the projection unit 15 projects the corresponding pattern to the appropriate position and moves it in the specified direction at the desired speed. Here, therefore, three tasks must be simultaneously solved. First, we need to create a user interface that allows the trainer to enter the desired combination of movements and translate it into accurate physical, geometric data (spatial position, velocity, direction, etc.), then send instructions to projector unit 15, and then projector unit 15 will implement these combinations of actions. The connection between the control computer 6 and the one or more scanning units 2 will be ensured by the multi-channel RF communication unit.

For purposes of the present invention, embodiments 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 them to its own control unit lb. Based on the instructions, the device controls the projection. The control unit lb sets one or more light sources 4, the number of light signals to be projected, the shape of the light signals and their movement path. The projector unit 15 comprises at least one light source-beam forming optical-scanning unit system. The light source-beam forming optical-scanning unit system includes a light source 4, a beam forming optical unit 3, and a scanning unit 2. The number of such source beam shaping (profiling) optical scanning units included in a particular projector 15 can be increased according to the needs of the user and the requirements of a particular task. The power supply of the unit can be solved by a mains power supply or a battery. In case of drone installation, only batteries can be used, while in fixed racks, the grid power supply is guaranteed to be safe.

During illumination, the light source or light sources 4 used must meet the following essential basic requirements.

1. The light pattern generated on the ground must be visible to the athlete participating in the training program. To achieve this goal, it is necessary to produce a sufficiently high intensity, on the other hand, to produce an appropriate illumination wavelength corresponding to the optical characteristics of a given ground. The appropriate selection of these two parameters is within the knowledge of one skilled in the art. This may be different if the grass must be clearly visible, or on parquet, asphalt, plastic, rubber, etc. on a paved surface.

2. Care should be taken to ensure that the applied beam or beams 7 do not present any risk to the athlete, coach, observer, spectator's eyes, physical health. According to our preliminary study, a spotlight given a diameter size of about 10 cm will be well identifiable and trackable on the field. For this task, relatively low power (several times 100mW) lasers and more recently dynamically developed high performance (several watts) LED light sources would be most suitable for use with their power supplies. Our preliminary experiments show that 3-4 colors (red, yellow, green, possibly blue) cover all commonly used types of coverage. Therefore, without being limited to these, two types of devices are disclosed as preferred embodiments. In one embodiment only one or more light sources 4 with a wavelength of one user defined dimension are included, while another embodiment has two or more light sources 4 illuminating in two or more colors, so that the device can be universally applied to all types of coverage types. By the use of three color component (red, green and blue, RGB) light sources 4, the light sources 4 may be, for example but not limited to, lasers or LEDs, in theory any color may be obscured, but the light scattering ability of the surface to be illuminated in the primary color wavelengths must be taken into account. In order for the system to be able to adapt to the current lighting conditions and the light scattering properties of the ground, the one or more light sources 4 must have controllable properties. With such complex devices, a variety of color-coded information can be projected.

Referring to fig. 2 and 3, the beam forming optical unit 3 is shown. The one or more light sources 4 are provided with optical elements [ lenses, mirrors, apertures/masks, optionally programmable Spatial Light Modulators (SLMs), etc. ] to accomplish the desired tasks and to provide the desired shape or shapes of the projection. The first element of the one or more beam-forming optical units 3 is a beam-deflecting mirror 8 a. The task is to convert the light beam 7 emitted by the light source 4 to a suitable size, diameter, so that the appropriate area of the aperture plate or spatial light modulator (not shown in fig. 2 and 3) responsible for forming a given beam shape is fully illuminated, but no more light intensity is lost.

As shown in fig. 3 and 4, in a second step the light beam 7 expanded to the appropriate size illuminates a beam forming unit 8b (not shown in fig. 4), which beam forming unit 8b is, in the embodiment shown in fig. 4, an aperture plate 10 provided with holes of various shapes, which is rotated by a motor controlled by a control unit lb (not shown in fig. 4) to produce the desired pattern that can be projected. In another embodiment the beam forming unit 8b (not shown in fig. 4) is a spatial light modulator 13, in which spatial light modulator 13 a suitable beam pattern can be generated by pixels (opaque pixels: 11; transparent pixels: 12), which can be switched on and off (variable throughput) by a control unit lb (not shown in fig. 4). By means of the above-mentioned elements it is achieved that the optical-scanning unit is formed by using light sources-beams corresponding to the number of players to be controlled, each player having a different beam shape.

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

For example, but not limited to, the shape generated by the beam forming unit 8b may be projected onto the ground by the following two methods.

i) In an embodiment of the device according to the invention, the simplest solution is to use sufficiently small so-called collimated light (fig. 2) when the beam shape leaving the aperture illuminates the field. The size of the projection shape may be influenced by the divergence (distortion) and projection distance of the light beam 7 that can be set under certain limits, and the projection position is determined by the scanning unit 2.

ii) in another embodiment of the apparatus according to the invention, less requirements (such as collimation) are placed on the light source(s) 4 when the (even diverging) light beam of the beam forming unit 8b passes the imaging lens 9 to the scanning unit 2 (fig. 3). In this case, an image of the aperture is projected by optical imaging, the size of the image is affected by the angle-magnification ratio of the optical system and the projection distance, and the exact position 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 passing through the shaping unit 8b with the desired parameters to project the light beam to the ground. In a preferred embodiment of the invention, the scanning unit 2 is a commercially available mirror scanner. The mirror scanner comprises two highly reflective mirrors at the applied wavelength, which are fixed to a galvanometer motor according to a conventional scanning geometry. The size of the mirrors is determined by the beam-forming unit 8b applied and, optionally, by the imaging optics 9, the speed and positioning accuracy of the galvanometer motor being largely in accordance with the requirements of our apparatus. The position and movement of the two motors, and thus the mirrors thereon, are adjusted by a control unit lb belonging to the projector 15 according to the task at hand.

The device constructed in the manner described differs from training aids currently in use from all of the components described above. Its high flexibility makes it unique in this field. Static and dynamic patterns can be projected and the shape of the directional lights used can also be changed during exercise. High precision adjustment of the scanning units allows any point of the field covered by the training to be located and dynamically with sufficient precision (without the need to divide and divide the field area into a given number of cells). The number of players participating in the training can be easily extended by switching new units. Displaying the desired shape on the field does not require altering the surface of the field, as will be discussed later.

The device according to the invention allows better simulation than any technique that supports training today, even in games and competitions at the international level.

The device according to the invention provides a more direct and accurate signal to one or more athletes as regards the intended movement, in comparison with the prior art, whatever their complexity, thus opening up a new field of view for the development and analysis possibilities of athletes and teams. These athletic movements may be displayed directly to the athlete: whether in a tournament or event, or a complete tournament or event, or even the movement of previous players or the actions of other players, and even the path of a ball in a ball game. Embodiments of the present invention provide simultaneous projection of multiple athletes, team members, entire teams, or even multiple teams. The projection is done using a two-dimensional geometry from the top to the ground, covering a specific motion. The task of an athlete is to follow the changes in the position of the geometric pattern around it. Athletes are immediately able to perceive their intended action, their direction, speed, cadence, and the difference between themselves and their intended action in real time in a competition context, in the same space as the game. Any required action, whether in real time or during the initial phase of the exercise, can be seen by the athlete, as desired, and may even be slowed or accelerated at any speed as desired.

With the device according to the invention, unlike the case of the techniques known in the prior art, the athlete not only receives the instructions theoretically, but also sees them directly in the practice during the simulated competition situation. This provides the opportunity for near immediate correction and more efficient exercise.

An improvement in game performance may be achieved through valuable, high quality exercises in simulated competition scenarios. The unique features of the present invention are the ability to effectively develop physical conditions, strategies, tactical skills, combined movements, thoughts, speed of decision making mechanisms, their creativity, their cognitive abilities and their cooperation of athletes and teams.

Through simulated competition scenarios, new tactical and personal solutions, team-based solutions, and more discreet versions thereof may be practiced, or even previously off-direction scenarios may be projected so that the correct scenario is found and practiced. Changes in practice are added to the tactical system of the team and the game intelligence of the athlete is developed.

The projection may stop at any point in time, after which the athlete must select creative solutions for a particular competition scenario in personal training, tactical training, or team sports to develop team collaboration. By stopping the projection in a simulated competition environment, using the device according to the invention, the athlete will be placed in a decision situation and, by means of an independent solution, the creativity, speed of the decision mechanism, efficiency and cooperation in case of team competition can be greatly improved. Assessment of the performance of the displayed game provides a coach with a wide range of analytical opportunities to develop athletes.

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

Embodiments of the present invention provide applications for facilitating soccer training.

In football games, the game load cannot be reconstructed with buoys, with arms, team levels or partial team levels or personally. Even for simple attacks, the fore or rear action cannot be reconstructed with spikes or buoys, since it mimics the static state and lacks the correct speed of movement, rhythm, timing and angle of change of direction. Since soccer is not a circular motion and involves extremely complex motions, it is more difficult to reconstruct game scenarios, competition loads and decision scenarios, which can be accurately simulated by embodiments of the present invention.

According to one embodiment of the invention, it is a major innovation to facilitate football training, which may provide new motivation to players every day, or even for subtasks, even to reach the level of international competition, which is essential for the development and maintenance of the state of competition. Athletes often cannot get training during team games because they know each other's abilities, patterns, and they are doing the same exercises.

Another limiting factor may be that team members have similar health levels among the teams. While differences in health levels between individuals may arise depending on certain genetic conditions, current body type, different levels of aggressiveness, and other factors, they do not affect the overall health level of the entire team. If some athletes still have some ability to affect the overall team's health level, this may already be considered the overall team's health level. For the development of teams, the influence of the performance of a few team members on the whole team is not effective enough, but it is effective enough, e.g. because they do the same exercise, they know each other's abilities, action patterns, and because the better performing team members are always limited by the poor performance of their teammates. When teammates inadvertently limit each other's development, they need new power, real game load-even if only subtasks-and decision scenarios-in order to develop. This is a good example in a one-to-one game of exercise, in a one-game between two genetically different athletes. If a faster player is able to drop another player within 10 meters, he will not go beyond 3 meters and then turn around and sprint a longer distance, as it is not reasonable in that game. However, a slower player limits his teammate's development because he does not force the teammate to the intensity and length of the sprint (much less the tempo, the angle of change of direction, and many other important factors); but a faster player of the opponent may force him to do so, for example, in a game situation. Similar problems exist, for example, in the case of differences in knowledge or motivation, or differences in competence. Thus, a better-performing athlete is not forced to maximize his exercise, which is limited to a performance where his partner is weaker. Because of this, he cannot develop normally, cannot achieve the maximum expression determined by his genes, his development may be arrested, and his expression and competitive status may deteriorate.

According to one embodiment of the invention, for the purpose of physical development, even a complete international game or a half-time break can be projected, the team member has to track each position. This can not only improve, but even measure the physical strength of an individual or even an entire team. Even a partial task, it can be added to the calendar.

According to embodiments of the present invention, the excellent team member's actions, sequence or running can be presented in the framework of personal training or from international competitions, thereby providing the team member with the power required on exercise.

The projected motion can be picked up by a back guard or front alone or even in pairs, even for defensive or offensive tasks. Embodiments of the apparatus according to the invention may also project the path of the ball so that the task may also be performed as a ball exercise. This task will help us to determine where the ranking of the excellent athlete is, how fast he is, and in his tempo, how far he is from his opponent in the game, how much is the angle he changes direction, and how he initiates a continuation event (sequence) at the end of the action line, further assisting this developing learning process. Initially, any motion can be freely slowed down, then even in real time or accelerated, it can be projected. The projection can be stopped at any given moment, leaving the athlete in a decision-making context and letting him choose the right solution, thus developing creativity, speed and efficiency of the decision-making mechanism. Selecting the correct solution among new variants of decision scenarios and their improved versions, pre-edited and projected solutions to fix previous errors will improve game intelligence and personal ability.

According to an embodiment of the present invention, even by projecting its motion, it is possible to prepare for the currently upcoming opponent.

According to another embodiment of the invention, not only the predetermined competition location can be projected, but also a simulation of a hypothetical, pre-constructed scenario.

The device according to the invention also provides many new applications in the field of tactical training and team collaborative development. As long as tactical instructions can only be communicated to athletes on boards, tablets or verbally on football stadiums (as team movements cannot be shown by other means), they can now be displayed in practice on stadiums.

The device according to the invention provides more precise control of the combined movements of several athletes at a time, which has so far been discussed only insignificantly, who will move and how to move to practice tactics, and coaches can only coach one athlete or several athletes at a time if it is aimed at showing exactly who moves and where. Simulating a real game situation in training situations, in training tactics situations, is even more difficult. With the device according to the invention, controlling, directing and moving in real time the complete part of a team, or the entire team or even a plurality of teams, can be achieved by slowing down or even speeding up.

The apparatus according to the invention also provides the possibility to stop the projection at any given moment, thus putting the team members in the decision context and allowing them to choose the right solution independently, thus developing their creativity, speed and efficiency of decision making and thus contributing very much to the development of the interplay. By practicing the improved solutions selected in the decision context and their modified versions, as well as pre-edited and projected new tactical changes, and finding solutions to correct the previous errors, the tactical architecture of the team is expanded and its team collaboration is developed.

The apparatus of the present invention provides a realistic simulation of game scenarios, whether these scenarios are previous errors to be corrected, scheduled actions, or actions of other teams. For example, a defensive counter attack after a ball is taken, passed, or lost for one outstanding team, or how an aggressive team breaks the defensive attack of another team in an international game may be projected. It can be shown how a good team attacks, transforms in certain situations: how fast, which part of the field, where, in what form, and how far the players are from each other.

It is possible to practice the defense against attacks or even those attacks belonging to different patterns. By projecting the path of the ball, the dribbling of the excellent team can be analyzed and parts of certain practices can be simulated simultaneously, for example: pass speed, their direction, solutions in the decision context, and the player's action without a ball.

The apparatus of the present invention provides an accurate picture of the choices of other professional athletes in certain game situations, the actions chosen in view of tactics and interactions, and how the best athlete moves within the field during the entire game.

The apparatus of the present invention also provides the opportunity to analyze the current opponent. Some strategic and strategic attacks of opponents can also be analyzed by practicing defending against them, or projecting mistakes in defending, and practicing how to use them. Athletes can experience opponent actions in training, and feel their speed, rhythm and direction, which makes preparation for competition easy and helps team win and succeed.

The invention allows for facilitating sports training.

The present invention allows for the projection of a player's scheduled running, or running in a previous race, or another player's running on a track during athletic training, thereby simulating a race.

The projection may be used to determine a desired running speed and tempo, to establish a running strategy for an athlete in a tournament or exercise, or to analyze another athlete's previous running or physically developing the athlete.

The present invention allows a particular athlete to complete a certain distance in certain seconds during a given workout, or even several times in a row, even by slowing down the previous individual's best performing run of the athlete to a desired level, depending on which preparation phase is performed and what they want to develop.

The present invention provides projections for development, practice, analysis to perform a 400 meter race of a show athlete, i.e., to simulate the speed of some portion of the run.

The present invention provides a projection of the personal best performance of an athlete's jump or other athletes' jumps during a high jump workout.

In the following, without limiting the invention, the use of the device according to the invention is mentioned in some other movements. For development and analysis purposes, the characteristics and features of the sport should be considered, and the invention is applied by simulating competition situations, complete competitions.

The present invention provides an application for facilitating american football exercises.

American football is much shorter than european football and when the player has the opportunity to position it in advance, the attack is more initiated from a fixed position. Thus, tactics may be more important. Because the match is composed of short sections, the match can be more accurately constructed, and attack and defense can be exercised. Athletes use many tactical variations that have been practiced in advance. With the help of the device of the invention, their training, analysis and development are significantly more efficient.

The invention can be used for football training.

The present invention provides applications for facilitating motor vehicle and motorcycle sports training.

The invention allows to design an ideal curve on the track in front of the car race, preferably with a predetermined degree of acceleration and deceleration and their position, and a maximum speed that can be safely assumed for this particular curve.

The present invention provides an application for facilitating training of young racing athletes.

All of the advantages of the invention described in more detail are of great importance in the training of young athletes. The specific goals that are to be achieved for younger racing athletes will become apparent later, at levels that they need to accommodate, both physically and mentally.

The invention allows for an entertaining athletic activity.

The invention allows for recreational use for non-competitive athletes, even slowing down the projection when necessary. The vast public can be satisfied (addressed) and participate in the world of sports and sports, whether they are children or adults. Items of ordinary schools and schools, universities, leisure centers, stadiums, hotels and adventure parks may be real-time or slow-motion projection real, romantic competitions, for example, where participants may test their physical ability, tactical skills, and gain real enjoyment, become part of a famous competition, and feel like they are competing with world-level athletes.

By means of the invention, the situation of the competition and the complete competition can be directly simulated by projecting the movement of one or more athletes during practice. In this way, the individual abilities of athletes, the physical condition of athletes and teams, their strategy, tactical preparation, their combined actions, their thinking, the efficiency and speed of their decision making mechanisms, their creativity, their cognitive abilities, their game intelligence and interactions can be improved. Athletes are immediately able to perceive their desired action, their direction, speed, cadence, and the difference between themselves and their desired action in real time in a competition context, in the same space as the game. Any movement required by the athlete can be seen, whether in real time or during the initial phase of the exercise, as desired, even by slowing or accelerating the movement at any speed.

In contrast to the prior art, using the device according to the invention, the athlete not only obtains instructions from the theoretically expected movement, but also sees these instructions directly in the practice during the simulated game. This gives us the opportunity to correct and exercise more efficiently almost immediately.

The projection may be stopped at any point in time, after which the athlete individually selects creative solutions for a particular competition scenario for tactical training or team collaboration to develop a team. With the help of the innovation, in a simulated competition situation, by stopping projection, athletes enter a decision-making situation and use their personal solutions, creativity, speed, efficiency of a decision-making mechanism and team cooperation can be greatly improved.

One of the advantages of our apparatus is that it can be used with commonly used types of venues, without requiring any transformation, modification, or treatment of the existing surface of the venue. There is no need to introduce new types of coatings which are likely to alter known and common physical parameters of the field (such as friction, flexibility, stiffness, etc.), that is, create different conditions for training athletes.

Displaying, projecting a given pattern to a site does not require, for example, a transparent cover, nor does it require a base structure (underground structural elements). All of this is important because changing physical parameters can affect the performance, muscles, endurance and reversal techniques of athletes, as well as their development in real-world situations. For example, when running on asphalt or on grass, it has a completely different effect on the muscles, joints and bones of the athlete. On the other hand, changing and changing the cover will incur a large additional cost. Another advantage of the system is that it can be applied to snow, mud and mud.

The device according to the invention can be used to detect, correct errors, analyze any situation and the performance of an athlete or opponent. By practicing some elements and their improved versions, strategic and tactical systems can be extended. In a never seen way, the combined movements of several athletes can be controlled. Assessment of the performance of the displayed game provides a coach with a wide range of analytical opportunities to develop athletes. This increased your training to a new level, with rapid and dramatic results.

In order to be the best performers in athletic competitions, they must train in competition situations, competition pressures, decision-making situations, and require new developmental motivation and maintenance of competitive status. The present invention provides such assistance and through diversified simulation of competition scenarios, training efficiency can be improved to an unprecedented level, opening up a new view for the development of athletes and teams to help them succeed.

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

Detailed Description

Example 1: application of the invention in assisting high jump exercise

For a high jump athlete, it is very important to have the best step sequence, step length, i.e. the determined step combination. The best offset combination is achieved by a device equipped with two wavelength light sources 4 on the blue rubber-plastic surface (red light) and the outdoor oblique path (green light). This is done by a single LSBF system using two different light sources 4.

Example 2: use of the invention for facilitating football training

For the situational exercise of 3 attackers-3 defenders, we constructed a system that generated, projected and moved groups of shapes of 3 pairs of 3 different beam shapes drawn in two different colors on the field lawn. To do this, six LSBF systems are incorporated into the projector 15, forming two sets of three different colors. In order to enable the players to follow an arbitrary direction of movement, i.e. not covering the projected multiple (6) beams 7, a coordinated projection system is placed on both sides of the current playing field.

Example 3: use of the invention to facilitate handball training

To train a defensive formation, the quinqued team athletes should move to a close arrangement between six and nine lines. At this time, five light beams having the same color are provided on the floor covering to be projected at the same time, the shapes of the light beams being different: circular, triangular, square, cross, and pentagonal. Thus, in this case, five LSBF systems are implemented in the projection unit 15.

Example 4: use of the invention to facilitate motorcycle training

To achieve the fastest loop speed, it is important to follow the curve of the curve with the greatest but safe speed. Each such arc is determined in advance and then fed back to the controller computer of the ground unit 14 which converts the data into track coordinates and velocity values. The projection unit 15 projects and moves a clearly visible light signal followed by a competitor on the asphalt pavement.

The device according to the invention facilitates the development of athletes and teams in different sports by projecting the sport actions expected by the athlete directly on a covering of a sports specific ground by means of light. The projection of these actions is done using data from previously captured imaging devices, or by recording data from analysis software from the location of a GPS encoder recorded on the athlete to be tracked. The device according to the invention is also suitable for projecting movements predetermined and designed by the trainer. The movement of the ball can also be tracked (e.g. using built-in GPS encoder data) and subsequently simulated. The device according to the invention can also be used for entertainment purposes.
