Description

Training evaluation device and method of using the same

The present invention relates to a training evaluation device and a method of using the same, which can effectively improve the motor ability of a trainee performing a dribbling motion along one or more circular lines and evaluate one or more trainings performed along the circular lines.

World-class soccer attackers maintain a certain formula and a sequence of actions from the moment they gain possession of the ball to the moment they make a valid shot.

Specifically, players perform a possession movement to keep the ball from leaving their feet, perform a forward movement to quickly run in the desired direction while simultaneously changing the direction of their body in the desired direction, and perform a transition movement to change direction flexibly and maintain balance before getting close to the opponent without reducing the accelerated speed while breaking through the opponent.

In addition, players often perform shots as the last step of dribbling, and these shots are often valid shots that are performed close to the ground. And these characteristics of possession or valid shots may have to be sequentially connected, like a formula. In addition, world-class soccer players often maintain a low posture and an athletic posture that allows for quick changes of direction and breakthrough.

However, general trainees and players may not be able to apply the above formula for possession and effective shooting due to a lack of awareness of direction and speed, and it may take a lot of time and effort to cultivate the high skills and athletic posture of world-class players.

Additionally, general dribbling training was often done by placing cone-shaped objects on the ground and dribbling around them.

However, although these dribbling drills can improve the feel of the ball when touching it with the feet, they can have the problem of irregular distance, angle, and strength when dribbling the ball due to the lack of an accurate reference line.

Furthermore, when such trainees perform soccer dribbling training, it is problematic that uniform evaluation criteria and training methods cannot be applied, and therefore, there is an increasing need for a training evaluation device and a method of using the same that can help trainees, such as general players and trainees, acquire exercise postures to maximize their athletic abilities, such as dribbling ability, and perform effective dribbling training based on such exercise postures.

The problem to be solved by the present invention is to sense a trainee performing dribbling training along one or more circular lines that touch each other, rather than the existing training method of circling around a member installed on the ground, and to perform such training using balls of various sizes, elasticities, shapes, and numbers, thereby effectively helping to develop the dribbling ability of world-class players, and to provide a training evaluation device and a method of using the same capable of systematically evaluating such training process.

The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the description below.

In order to solve the above-described problem, according to an embodiment of the present invention, a training evaluation method includes the steps of: using a camera to film a training process of a trainee performing one or more training exercises while moving a ball with the feet along one or more circular lines arranged on the ground and touching each other, thereby generating filming data for multiple body configurations of the trainee, the ball, and the circular lines; and generating sensing data of at least one of the positions, speeds, and accelerations of the trainee, the feet, and the ball from the filming data; using a processor, evaluating multiple items included in the one or more training exercises based on at least one of the circular lines, the relative positions of the feet and the ball, the speeds of the feet and the ball, and the posture of the trainee; and using a processor, calculating a score of the one or more training exercises of the trainee based on the evaluations of the multiple items, wherein each of the one or more training exercises may be performed along one or more circular lines having at least one different diameter and a different different contact position. Each of the one or more training exercises may be performed using balls having at least one different different elasticity, size, and shape.

Specific details of other embodiments are included in the detailed description and drawings.

According to the present invention as described above, it has various effects as follows.

The present invention has the effect of more effectively evaluating the galloping posture, dribbling ability, etc. of a trainee by sensing a trainee performing multiple training exercises using one or more balls of different sizes, elasticities, shapes, and numbers along one or more circular lines that touch each other, and consequently improving the trainee's soccer skills.

FIGS. 4 to 15 are drawings for explaining a training evaluation device, system, and method of using the same according to one embodiment of the present invention.

Referring to FIGS. 1 and 2, the training evaluation system (1000) and device (100) of the present invention are training evaluation systems (1000) and devices (100) that can effectively improve the dribbling ability of a trainee performing training by evaluating multiple trainings by sensing movements of a trainee moving a ball with the feet through a dribbling motion along one or more circular lines. The training evaluation system (1000) includes a training evaluation device (100) and a trainee terminal (200).

Specifically, the training evaluation device (100) includes a processor (110), a communication unit (120), a sensing unit (130), an output unit (140), and a storage unit (150).

The processor (110) of the training evaluation device (100) is a component that receives data on the position, speed and acceleration of each of the trainee, the trainee's feet, the circular line and the ball sensed by the sensing unit (130), and uses this to calculate the relative positions of the circular line, the ball and the feet, the speed of the feet, the speed of the ball, the position of the trainee's body composition, the trainee's posture, etc., and uses the calculated data to generate evaluation data for one or more trainings that the trainee is performing (or has already performed).

The communication unit (120) of the training evaluation device (100) is a component that connects the training evaluation device (100) and an external device such as a trainee terminal (200) to each other so that they can communicate. The communication unit (120) can be connected to the trainee terminal (200) and further to an external database using wired/wireless communication to transmit and receive various data and signals. Specifically, the communication unit (120) can receive trainee characteristic data such as the trainee's height, weight, and age, as well as the trainee's existing training data, from the trainee terminal (200), and can transmit training evaluation data after one or more trainings are performed to the trainee terminal (200).

The sensing unit (130) of the training evaluation device (100) is configured to generate sensing data by sensing the position, speed, acceleration, etc. of each of a trainer performing one or more trainings, the trainer's feet, and a ball used in training.

The sensing unit (130) may include at least one of a camera, a vibration sensor, an acceleration sensor, and a pressure sensor.

Specifically, the camera of the sensing unit (130) is configured to film the entire training process of the trainee and generate filming data on multiple body compositions, balls, and circular lines of the trainee in real time.

The vibration sensor of the sensing unit (130) is attached to the body components of the trainee (e.g., head, shoulders, arms, wrists, hands, chest, back, waist, stomach, pelvis, thighs, knees, ankles, feet, etc.) and is configured to sense the vibration of each body component.

In addition, the acceleration sensor of the sensing unit (130) is attached to the body structure of the above-mentioned trainee and is configured to sense the real-time speed and acceleration of each body structure.

And, the pressure sensor of the sensing unit (130) may be attached to multiple points of the contact surface (sole) between the trainer's foot and the ground while the trainer is standing on the ground, or may be attached to multiple points of the contact surface with the trainer's sole on the inside of the shoe worn by the trainer, or may be attached to the bottom surface of the shoe. Such a pressure sensor may sense real-time pressure between multiple points of the trainer's foot and the ground.

The output unit (140) of the training evaluation device (100) is configured to provide evaluation data produced by the processor (110) to a trainee or manager. The output unit (140) may include a display unit, and in this case, the display unit may provide the evaluation data by displaying it on a screen. In addition, the output unit (140) may include a printer, and the printer may output the evaluation data on paper or the like and provide it to the trainee.

The storage (150) of the training evaluation device (100) can store various trainee data, trainee training evaluation data, etc. received from the trainee terminal (200). In various embodiments, the storage (150) can include at least one type of storage medium among a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, an SD or XD memory, etc.), a random access memory (RAM), a static random access memory (SRAM), a read-only memory (ROM), an electrically erasable programmable read-only memory (EEPROM), a programmable read-only memory (PROM), a magnetic memory, a magnetic disk, and an optical disk.

The above components of the training evaluation device (100) are operably connected to each other and can perform various commands to provide a user interface for displaying evaluation data. In addition, the components of the training evaluation device (100) are not limited thereto, and other components may be added as needed, or some components may be implemented as external devices and configured to transmit and receive signals and data through communication with the remaining components of the training evaluation device (100).

And, the trainee terminal (200) of the training evaluation system (1000) is a terminal used by a trainee (trainer) who conducts one or more trainings through the training evaluation system (1000). The trainee terminal (200) is an electronic system that requests data for evaluation and provides a user interface for displaying evaluation data, and may include at least one of a smartphone, a tablet PC (Personal Computer), a laptop, and/or a PC.

Next, the evaluation method performed by the dribble training evaluation device (100) and system (1000) will be described in more detail.

Referring to FIGS. 3 to 15, first, the training evaluation device (100) uses a sensing unit (130) to move a ball through the feet along one or more circular lines placed on the ground and in contact with each other, and senses at least one of the position, speed, and acceleration of each of the trainer, the feet, and the ball performing one or more trainings (S110).

Next, the training evaluation device (100) evaluates multiple items included in one or more trainings based on at least one of the relative positions of the circular line, the feet, and the ball, the speed of the feet and the ball, and the posture of the trainer using the processor (110) (S120).

Specifically, the evaluation method performed by the training evaluation device (100) and system (1000) can perform 'evaluation of dribbling posture using a circular line'.

Specifically, world-class soccer attackers display the following characteristics: the ball never leaves their feet (possession); quick directional awareness and movement speed, such as running at full speed toward the opponent's goal within 1 second after catching the ball from any direction (forward); flexibly changing direction and maintaining balance, such as not stopping when an opponent is in front of them and getting past them before they get close (transition); passing through narrow spaces even when opposing players are densely packed (transition); finishing with a significantly higher number of shots and a very short shooting interval in front of the goal (shooting); and shooting many shots into the ground (effective shots). These characteristics of possession and effective shots should be connected in order, as if by a formula.

However, general players may not be able to apply the above formula from possession to valid shooting due to a lack of awareness of direction and speed. In other words, even if they possess the ball, they may hesitate for more than a second and, when an opposing player runs to steal the ball, they may often pass back as if to avoid the pressure.

Therefore, in order for these general players to acquire smooth movements like world-class players from possession to effective shooting, we developed training in the galloping posture and training using a circular line, respectively, and developed a systematic and specific evaluation method for this training.

First, we will explain the training and evaluation of the posture. The galloping posture is a posture that includes all of the following: the distance between the ball and the feet is close, the power of kicking the ball is not strong, so the ball does not bounce out (ball keeping), the propulsion as if pouring forward, so that a quick reaction speed to the ball can be shown (propulsion), and the ability to maintain the body's balance when increasing acceleration (balance, body control). The evaluation can be performed by evaluating each of the contents of multiple items included in the galloping posture evaluation items in <Table 1> below according to the corresponding evaluation method.

<Table 1>

Each of items 1 to 14 of the galloping posture evaluation items in Table 1 above may correspond to each of FIGS. 4(a) to 4(m).

In addition, multiple items of the galloping posture evaluation items can be sensed by at least one of the camera, vibration sensor, acceleration sensor, and pressure sensor of the sensing unit (130) of the training evaluation device (100).

The processor (110) can calculate a score for each of the multiple items by performing an evaluation of each of the multiple items using sensing data. In addition, the processor (110) can calculate an evaluation score for the galloping posture of the corresponding trainee by adding up all of the calculated scores for each of the multiple items.

The evaluation of the galloping posture can be continuously performed in each of the multiple trainings that include the evaluation of the dribbling posture using the circular line described below. That is, the evaluation of the trainee's dribbling posture using the circular line can include multiple trainings that variously set the circular line, the ball, etc., and the evaluation items for each of the multiple trainings can include the evaluation items for the galloping posture. That is, the galloping posture can be continuously evaluated while performing the evaluation of the dribbling posture using the circular line.

Next, the 'evaluation of dribbling posture using a circular line' of the evaluation method performed by the training evaluation device (100) and system is described.

FIG. 5 is a drawing for explaining a training evaluation device (100), system (1000) and method of using the same according to one embodiment of the present invention, and a conventional dribble training method that is different.

Referring to Fig. 5, the existing dribbling training could be conducted by dribbling the ball while moving in a shape as indicated by a dotted line between two objects installed on the ground. In the case of such existing training, the trainee could get used to the feeling of the ball touching the foot, but there may not be an accurate dribbling reference line because only the positions of the two objects were set. Accordingly, the trainee could not train about the distance, angle, and strength of dribbling the ball, and there was a problem because only irregular dribbling distance, angle, and strength could be acquired.

In contrast, the training evaluation device (100), system and method of using the same according to one embodiment of the present invention are characterized by performing training by dribbling a ball along one or more circular lines arranged on the ground as shown in FIG. 6. Specifically, referring to FIG. 6(a), the plurality of circular lines may include a first circular line (CL1) to a fifth circular line (CL5). That is, each of one or more trainings may be performed along one or more circular lines having at least one different diameter and contact position.

Specifically, the first circular line (CL1) and the second circular line (CL2) have the same size (diameter) as each other and are externally connected to each other at one point. In addition, the third circular line (CL3) and the fourth circular line (CL4) have a size (diameter) smaller than that of the first circular line (CL1) and the same size as each other and are externally connected to each other at one point. At this time, the external contact point of the third circular line (CL3) and the fourth circular line (CL4) may be the same as the point of contact (external contact point) of the first circular line (CL1) and the second circular line (CL2). That is, the third circular line (CL3) and the fourth circular line (CL4) may be externally connected to each other at the point of contact of the first circular line (CL1) and the second circular line (CL2).

In addition, the third circular line (CL3) may be arranged inside the first circular line (CL1) and may be inscribed with the first circular line (CL1), and the fourth circular line (CL4) may be arranged inside the second circular line (CL2) and may be inscribed with the second circular line (CL2). In addition, the centers of the first circular line (CL1) to the fourth circular line (CL4) may all be arranged on the same straight line.

At this time, the diameters of the first circular line (CL1) and the second circular line (CL2) may be, for example, 80 cm, and the diameters of the third circular line (CL3) and the fourth circular line (CL4) may be, for example, 40 cm, which is half the diameter of the first circular line (CL1). However, this is not limited thereto.

And, the size (diameter) of the fifth circular line (CL5) may be smaller than the size (diameter) of the first circular line (CL1) to the fourth circular line (CL4), and the fifth circular line (CL5) may be in contact with the first circular line (CL1). At this time, the center of the fifth circular line (CL5) may not be arranged on a straight line connecting the centers of each of the first circular line (CL1) to the fourth circular line (CL4). That is, the distance between the straight line connecting the centers of each of the first circular line (CL1) to the fourth circular line (CL4) and the center of the fifth circular line (CL5) may be smaller than the radius of the first circular line (CL1). In addition, the distance between the center of the fifth circular line (CL5) and the center of the first circular line (CL1) may be smaller than all of the distances between the centers of the fifth circular line (CL5) and each of the second circular line (CL2) to the fourth circular line (CL4).

At this time, dribble training using a circular line can be performed by selecting at least one of the first circular line (CL1) to the fifth circular line (CL5). That is, as shown in Fig. 6(b), only the first circular line (CL1) and the second circular line (CL2) (basic set) can be selected to perform one dribble training.

In this way, the training evaluation device (100), system and method of using the same according to one embodiment of the present invention can, in addition to performing an evaluation of a galloping posture and performing an evaluation of dribbling training using a circular line, further perform an evaluation of whether the outside line of the foot (the outer side among the inner and outer sides of the foot) is used, and can perform an evaluation of a plurality of trainings performed by a plurality of balls having different elasticity, size and shape in at least one.

In this regard, to describe in more detail the dribbling training and its evaluation, one or more trainings of step (S110) may include at least one of the first to eighth trainings.

First, referring to FIG. 7, the first training may be the 'Without ball training', which may mean training in which the trainee walks along a circular line without a ball. The first training may include training 1-1 in which the trainee walks along a circular line using both feet as shown in FIG. 7(a), and training 1-2 in which the trainee walks using only one foot (e.g., the right foot) of the two feet while bringing the outer side of the foot into contact with the circular line as shown in FIG. 7(b). In addition, the processor (110) of the dribble training evaluation device (100) may evaluate the first training according to the contents and evaluation methods of each of the plurality of items included in the evaluation of the first training in <Table 2> below.

<Table 2>

Each of the 1-1 and 1-2 trainings included in the 1st training may include an evaluation of all the items for the galloping posture evaluation. That is, the evaluation of the galloping posture may be continuously evaluated during the evaluation of the 1st training.

Additionally, multiple items of the first training can be sensed by at least one of a camera, a vibration sensor, an acceleration sensor, and a pressure sensor of the sensing unit (130) of the training evaluation device (100).

The processor (110) can calculate a score for each of the plurality of items by performing an evaluation of each of the plurality of items using sensing data. In addition, the processor (110) can calculate an evaluation score for the first training of the corresponding trainee by adding up all of the calculated scores for each of the plurality of items.

Next, referring to FIG. 8, the second training may refer to 'general ball training', which may mean training in which a trainee dribbles a ball along a circular line and walks using a general soccer ball that conforms to international standards. The second training may include training 2-1 in which the trainee dribbles a ball along a circular line using both feet as in FIG. 8(a), training 2-2 in which the trainee dribbles the ball using only one foot (e.g., the right foot) of the two feet while bringing the outer side (the outside surface) of the foot into contact with the circular line as in FIG. 8(b), and training 2-3 in which the trainee dribbles the ball using only one foot (e.g., the right foot) of the two feet while bringing the inner side (the inside surface) of the foot into contact with the circular line as in FIG. 8(c). And, the processor (110) of the training evaluation device (100) can evaluate the second training according to the contents and evaluation method of each of the plurality of items included in the evaluation of the second training in <Table 3-1>, <Table 3-2>, and <Table 3-3> below.

<Table 3-1>

<Table 3-2>

<Table 3-3>

Each of the 2nd training, including the 2nd training, the 2nd training, and the 2nd training, may include evaluations of all the items for the galloping posture evaluation. That is, the evaluation of the galloping posture may be continuously evaluated during the evaluation of the 2nd training.

In addition, multiple items of the second training can be sensed by at least one of the camera, vibration sensor, acceleration sensor, and pressure sensor of the sensing unit (130) of the training evaluation device (100), and the processor (110) can perform evaluation of each of the multiple items using the sensing data, thereby calculating a score for each of the multiple items. In addition, the processor (110) can calculate an evaluation score for the second training of the corresponding trainee by adding up all of the calculated scores of each of the multiple items.

Next, referring to FIG. 9, the third training may refer to training in which the trainee walks along a circular line while dribbling a second ball (B2) having greater elasticity than the general ball used in the second training, as the 'highly elastic ball training'. Specifically, the third training may include training 3-1 in which the trainee dribbles the second ball (B2) using only one foot (e.g., the right foot) of the two feet while bringing the outer side (outside surface) of the foot into contact with the circular line, as shown in FIG. 9(a), and training 3-2 in which the trainee dribbles the first ball (B1) using only one foot (e.g., the right foot) of the two feet while bringing the outer side (outside surface) of the foot into contact with the circular line as an additional training, as shown in FIG. 9(b). In this way, since training 3-2 using the general first ball (B1) as an additional training is included in training 3, the trainee can apply the skills acquired through training 3-1 to the first ball (B1).

And, the processor (110) of the training evaluation device (100) can evaluate the 3-1 training according to the content and evaluation method of each of the multiple items included in the evaluation of the 3-1 training of <Table 4> below, and in the case of the 3-2 training, it can be evaluated according to the content and evaluation method of each of the multiple items included in the evaluation of the 2-2 training of <Table 3-2> described above.

<Table 4>

Each of the 3-1 and 3-2 trainings included in the 3rd training may include evaluations of all items of the galloping posture evaluation. That is, the evaluation of the galloping posture may be continuously evaluated during the evaluation of the 3rd training.

In addition, multiple items of the third training can be sensed by at least one of the camera, vibration sensor, acceleration sensor, and pressure sensor of the sensing unit (130) of the dribble training evaluation device (100), and the processor (110) can perform evaluation of each of the multiple items using the sensing data, thereby calculating a score for each of the multiple items. In addition, the processor (110) can calculate an evaluation score for the third training of the corresponding trainee by adding up all of the calculated scores for each of the multiple items.

Next, referring to FIG. 10, the fourth training may refer to 'small ball training', which may refer to training in which the trainee walks along a circular line while dribbling a third ball (B3) (e.g., a tennis ball) that is smaller than the general ball used in the second training. Specifically, the fourth training may include training 4-1 in which the trainee dribbles the third ball (B3) using only one foot (e.g., the right foot) while contacting the outer side of the foot with the circular line, as shown in FIG. 10, and training 4-2 in which the trainee dribbles the first ball (B1) using only one foot (e.g., the right foot) while contacting the outer side of the foot with the circular line as an additional training. In this way, since training 4-2 using the general first ball (B1) as an additional training is included in training 4, the trainee can apply the skills acquired through training 4-1 to the first ball (B1).

And, the processor (110) of the training evaluation device (100) can evaluate the 4-1 training according to the content and evaluation method of each of the multiple items included in the evaluation of the 4-1 training of <Table 5> below, and in the case of the 4-2 training, it can be evaluated according to the content and evaluation method of each of the multiple items included in the evaluation of the 2-2 training of <Table 3-2> described above.

<Table 5>

Each of the 4-1 and 4-2 trainings included in the 4th training may include evaluations of all the galloping posture evaluation items. That is, the evaluation of the galloping posture may be continuously evaluated during the evaluation of the 4th training.

In addition, multiple items of the fourth training can be sensed by at least one of the camera, vibration sensor, acceleration sensor, and pressure sensor of the sensing unit (130) of the training evaluation device (100), and the processor (110) can perform evaluation of each of the multiple items using the sensing data, thereby calculating a score for each of the multiple items. In addition, the processor (110) can calculate an evaluation score for the fourth training of the corresponding trainee by adding up all of the calculated scores of each of the multiple items.

Next, referring to FIG. 11, the fifth training is 'large-sized and highly elastic ball training', which may mean training in which the trainee walks along a circular line while dribbling a fourth ball (B4) (e.g., a tennis ball) that is larger and more elastic than the general ball used in the second training. Specifically, the fifth training may include the fifth-first training in which the trainee dribbles the fourth ball (B4) using only one foot (e.g., the right foot) while bringing the outer side (outside surface) of the foot into contact with the circular line, as shown in FIG. 11, and the fifth-second training in which the trainee dribbles the first ball (B1) using only one foot (e.g., the right foot) while bringing the outer side (outside surface) of the foot into contact with the circular line as an additional training. In this way, since the fifth training in which the trainee uses the general first ball (B1) as an additional training is included in the fifth training, the trainee can apply the skills acquired through the fifth-first training to the first ball (B1).

And, the processor (110) of the training evaluation device (100) can evaluate the 5-1 training according to the content and evaluation method of each of the multiple items included in the evaluation of the 5-1 training of <Table 6> below, and in the case of the 5-2 training, it can be evaluated according to the content and evaluation method of each of the multiple items included in the evaluation of the 2-2 training of <Table 3-2> described above.

<Table 6>

Each of the 5-1 and 5-2 exercises included in the 5th training may include an assessment of all the galloping posture evaluation items. That is, the assessment of the galloping posture may be continuously assessed during the assessment of the 5th training.

At this time, the fifth training may include an evaluation item (item 1) that checks whether the number of times the trainer's foot touches the fourth ball (B4) on one circular line is three or less. The fourth ball (B4) may be larger and more elastic than the first ball (B1), and reflecting these characteristics of the fourth ball (B4), the number of times the contact is limited to three or less, unlike the number of times the general ball, the first ball (B1), touches six to seven times.

Additionally, multiple items of the fifth training can be sensed by at least one of a camera, a vibration sensor, an acceleration sensor, and a pressure sensor of the sensing unit (130) of the training evaluation device (100).

The processor (110) can calculate scores for each of the multiple items by performing evaluations of each of the multiple items using sensing data.

Additionally, the processor (110) can calculate an evaluation score for the fifth training of the trainee by adding up the calculated scores of each of the multiple items.

Next, referring to FIG. 12, the sixth training may refer to training in which the trainee walks along a circular line while dribbling the ball using a fifth ball (B5) (e.g., a rugby ball) that is not a sphere with a constant radius compared to the general ball used in the second training, and has different major and minor axes. Specifically, the sixth training may include training 6-1 in which the trainee dribbles the fifth ball (B5) using only one foot (e.g., the right foot) of the two feet while making contact with the outer side of the foot and the circular line, as shown in FIG. 12, and training 6-2 in which the trainee dribbles the first ball (B1) using only one foot (e.g., the right foot) of the two feet while making contact with the outer side of the foot and the circular line, as additional training. In this way, since the 6-2 training using the general public 1st public offering (B1) as additional training is included in the 6th training, the skills acquired by the trainee through the 6-1 training can be applied to the 1st public offering (B1).

And, the processor (110) of the training evaluation device (100) can evaluate the 6-1 training according to the content and evaluation method of each of the multiple items included in the evaluation of the 6-1 training of <Table 7> below, and in the case of the 6-2 training, it can be evaluated according to the content and evaluation method of each of the multiple items included in the evaluation of the 2-2 training of <Table 3-2> described above.

<Table 7>

Each of the 6-1 and 6-2 exercises included in the 6th training may include an assessment of all the galloping posture assessment items. That is, the assessment of the galloping posture may be continuously assessed during the assessment of the 6th training.

Additionally, multiple items of the sixth training can be sensed by at least one of a camera, a vibration sensor, an acceleration sensor, and a pressure sensor of the sensing unit (130) of the training evaluation device (100).

The processor (110) can calculate scores for each of the multiple items by performing evaluations of each of the multiple items using sensing data.

Additionally, the processor (110) can calculate an evaluation score for the sixth training of the trainee by adding up the calculated scores of each of the multiple items.

Next, referring to FIG. 13, the 7th training is a 'multiple ball training', which may mean training in which the trainee walks along a circular line while dribbling the ball using the 6th ball (B6), which is a multiple number (for example, 2 or 3) of the regular balls used in the 2nd training.

Specifically, the seventh training may include the 7-1 training to dribble two general sixth balls (B6) using only one foot (e.g., the right foot) while making contact with the outside surface of the foot and the circular line, as shown in Fig. 13(a); the 7-2 training to dribble three general sixth balls (B6); and the 7-3 training to dribble one first ball (B1) using only one foot (e.g., the right foot) while making contact with the outside surface of the foot and the circular line as an additional training. In this way, since the 7-3 training using one first ball (B1) is included in the 7 training as an additional training, the trainer can apply the skills acquired through the 7-1 training and the 7-2 training while dribbling one ball.

And, the processor (110) of the training evaluation device (100) can evaluate each of the 7-1 training and the 7-2 training according to the content and evaluation method of each of the multiple items included in the evaluation of the 7-1 training of <Table 8> below, and in the case of the 7-3 training, it can be evaluated according to the content and evaluation method of each of the multiple items included in the evaluation of the 2-2 training of <Table 3-2> described above.

<Table 8>

Each of the 7-1 to 7-3 exercises included in the 7th training may include evaluations of all the galloping posture evaluation items. That is, the evaluation of the galloping posture may be continuously evaluated during the evaluation of the 7th training.

Additionally, multiple items of the 7th training can be sensed by at least one of a camera, a vibration sensor, an acceleration sensor, and a pressure sensor of the sensing unit (130) of the training evaluation device (100).

The processor (110) can calculate scores for each of the multiple items by performing evaluations of each of the multiple items using sensing data. In addition, the processor (110) can calculate an evaluation score for the seventh training of the corresponding trainee by adding up all of the calculated scores for each of the multiple items.

Next, referring to FIG. 14, the 8th training may refer to training in which a ball is dribbled along lines according to various combinations of the first circular line (CL1) to the fifth circular line described in FIG. 6(a) using the general ball used in the 2nd training, as a 'various circular line training'. Specifically, the 8th training may include training in which the first ball (B1) is dribbled using only one foot (for example, the right foot) out of the two feet while making contact with the outer surface of the foot and the circular line, as shown in FIG. 14. Additionally, the eighth training may include training including the first circular line (CL1) and the fifth circular line (CL5), training including the first circular line, the second circular line (CL2), and the fifth circular line (CL5), training including the first circular line (CL1), the fourth circular line (CL4), and the fifth circular line (CL5), training including the first circular line (CL1) and the fourth circular line (CL4), etc.

At this time, each of the multiple trainings (trainings using different circular lines) included in the 8th training may include evaluations of all the galloping posture evaluation items. That is, the evaluation of the galloping posture may be continuously evaluated during the evaluation of the 8th training.

Additionally, multiple items of the 8th training can be sensed by at least one of a camera, a vibration sensor, an acceleration sensor, and a pressure sensor of the sensing unit (130) of the training evaluation device (100).

The processor (110) can calculate scores for each of the multiple items by performing evaluations of each of the multiple items using sensing data. In addition, the processor (110) can calculate an evaluation score for the 8th training of the corresponding trainee by adding up all of the calculated scores for each of the multiple items.

The evaluation of each of the first to eighth trainings performed by the training evaluation device (100) may include at least one of the first to eighth trainings. That is, some of the first to eighth trainings may not be included in the evaluation.

At this time, the order of the first to eighth trainings can be performed in sequence. Accordingly, multiple trainings can be performed in the order of different balls (the first ball (B1) to the sixth ball (B6)). In this way, as the training is performed in the order of the first ball (B1) to the sixth ball (B6), there is an effect of more effectively acquiring the entire flow of possession, advance, transition, shooting, and effective shooting based on the galloping posture.

That is, referring to Fig. 15, by performing the evaluation according to the flow of training including at least one of the first to eighth trainings, in the case of 'possession', the technique of not letting the ball leave the foot through the power of the foot, the height of the foot, and the left foot can be acquired, and in the case of 'forward', the technique of quickly moving the body while the ball is attached to the foot can be acquired through the improvement of agility, reaction speed, and instantaneous speed. In addition, in the case of 'transition', the elasticity and ball keeping (possession) at the diagonal line of figure 8, which is the contact point between two circular lines, can be improved, so that the elastic movement and body balance can be improved when changing direction. In addition, in the case of 'shooting', the distance between the ball and the foot can be narrowed based on the improved galloping posture through the training evaluation, and the shooting can be performed within the time frame after the dribbling is finished, and the accuracy of the contact point between the foot and the ball when shooting can be improved. And, in the case of 'valid shooting', the distance between the trainee's two knees is reduced due to the improvement of the galloping posture, so that the movement of the ball can be close to the ground when shooting.

In addition, the evaluation method of the present invention can contribute to the stable acquisition of skills by allowing the trainee to test skills acquired through training using a special ball rather than a general ball (the first ball (B1)) through additional training using the general ball (the first ball (B1)) by including some or all of the additional training using the first ball (B1) in each of the training using the second ball (B2) to the sixth ball (B6).

Next, the training evaluation device (100) calculates a score of one or more trainings of the trainee based on the evaluation of a plurality of items using the processor (110) (S130). As described above, the processor (110) may perform some or all of the first to eighth trainings and may perform an evaluation of a plurality of items included in each training. For example, the processor (110) may evaluate each item as O/X, and the evaluation results for each of the plurality of items may be added together to calculate an evaluation score of each training. The processor (110) may transmit evaluation data to the communication unit (120) and/or the output unit (140), and the communication unit (120) may transmit the evaluation data to the trainee terminal (200), and the output unit (140) may display and transmit the evaluation data to the trainee of the dribble training evaluation device (100) using a display unit or the like.

According to one embodiment, the training evaluation device (100) can calculate scores for each of the plurality of sub-trainings included in the eighth training (various circular line training) and perform evaluation for the ninth training based on the scores for each of the plurality of sub-trainings.

Specifically, the eighth training may include multiple sub-trainings using different circular lines. For example, the eighth training may include a first sub-training using the first circular line (CL1) and the fourth circular line (CL4), a second sub-training using the first circular line (CL1) and the fifth circular line (CL5), and a third sub-training using the first circular line (CL1), the second circular line (CL2), and the fifth circular line (CL5). In this case, the evaluation score of the first sub-training may be 10 points, the evaluation score of the second sub-training may be 3 points, and the evaluation score of the third sub-training may be 5 points.

The processor (110) of the training evaluation device (100) can sort the first to third sub-trainings in order of trainings having high to low evaluation scores, and each of the sorted sub-trainings of the eighth training can correspond to each of the plurality of sub-trainings of the ninth training. That is, the first to third sub-trainings of the eighth training can be sorted in the order of the first sub-training, the third sub-training, and the second sub-training in descending order of the evaluation scores, and each of the plurality of sub-trainings included in the ninth training can be composed of such sorted sub-trainings. In addition, each of the plurality of sub-trainings included in the ninth training can utilize a circular line used in a corresponding sub-training among the eighth training. That is, the first sub-training of the 9th training can use the first circular line (CL1) and the fourth circular line (CL4), the second sub-training can use the first circular line (CL1), the second circular line (CL2), and the fifth circular line (CL5), and the third sub-training can use the first circular line (CL1) and the fifth circular line (CL5).

In this way, the sub-trainings that constitute the 9th training performed after the 8th training can include the sub-trainings included in the 8th training arranged in descending order of their respective evaluation scores and the sub-trainings that apply the corresponding circular lines. Accordingly, based on the evaluation results of the 8th training performed using various circular lines, the trainings rearranged in order from the circular lines with easy difficulty to the circular lines with high difficulty can be provided as the 9th training. Therefore, there is an effect of being able to provide the 9th training that is suitable for the trainee's ability after the 8th training.

According to one embodiment, the communication unit (120) of the training evaluation device (100) can receive trainee information including the trainee's height, weight, body type, age, training record, etc. from the trainee terminal (200).

The processor (110) can use this trainer information to set a customized training environment for the trainer. For example, the size (diameter) of the first circular line (CL1) to the fifth circular line (CL5), the number of times the foot comes into contact with the ball in one circular line when performing the fifth training, etc. can be set based on the trainer's height. That is, as the trainer's height increases, the size of the circular line and the number of times the foot comes into contact with the ball in the fifth training can increase.

According to one embodiment, the processor (110) of the training evaluation device (100) can further evaluate Lacricosta training, two-touch training, drag training, stem-of training, no-line training, 360-degree decompression (right decompression, left decompression, straight decompression) training, training to convert an aerial ball into a ground ball adjacent to the ground, training to evaluate the speed at which the trainer recognizes the goal, direct breakthrough training, training to improve distance perception when switching, galloping shooting posture training, shooting training, passing training (pass and two-run, triangle), space training (pass and pace stop and move, perimeter check, line control), etc.
