Description

Technical Field

[0001] This invention relates to the field of motion training technology, and in particular to a motion learning aid and its usage method. Background Technology

[0002] In traditional tennis training, beginners typically rely on coaching or self-study via videos. During this process, the accuracy of the learned movements is influenced by both the coach's and the learner's own understanding, easily leading to errors in the sequence of force application. Currently, the accuracy of most learned movements is judged primarily by the coach or by the trainee comparing their movements to videos. Without professional coaching guidance, trainees struggle to identify their own mistakes and correct them, hindering skill improvement and potentially causing injury. Currently, there is a lack of auxiliary training devices that can self-correct during the learning process, addressing the correct sequence of force application and the proper coordination of different stages.

[0003] Chinese invention patent application CN104474703A discloses a walking training system and method for people with intellectual disabilities.

[0026] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0027] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] On the one hand, embodiments of the present invention provide a motion learning assistance device, such as... Figure 1-4 As shown, it includes a main controller 1 and a strap 2, wherein:

[0029] The strap 2 includes at least two of the following: shoulder straps, elbow straps, wrist straps, waist straps, thigh straps, calf straps, and ankle straps;

[0030] Each strap 2 is equipped with a vibration module 3. The vibration module 3 includes a control unit 31 and a vibration motor 32 connected to the control unit 31. The vibration motor 32 is responsible for the vibration function and generates vibration under the control of the main controller 3 and the control unit 31 to remind the trainee that the limb on that side needs to move or exert force.

[0031] The main controller 1 and the control unit 31 inside the strap 2 are wirelessly connected.

[0032] When in use, the trainee puts on the corresponding straps 2 on the body parts according to the movements to be learned, or puts on all the straps 2 on the body. Then the trainee begins to practice the movements. The main controller 1 controls the straps 2 on different parts of the body to vibrate in sequence according to the force exertion of the movements (specifically, the main controller 1 controls the vibration motor 32 of the corresponding body parts to vibrate through the control unit 31 in each strap 2) to remind the trainee to exercise the corresponding parts of the body.

[0033] The motion learning aid device of this invention is used by trainees who need to learn or standardize motions. By vibrating multiple limb points with vibration motors, it can improve limb coordination, accelerate the motion learning process, and improve motion learning efficiency.

[0034] In this embodiment of the invention, the strap 2 can be a band-like structure that conforms to the human body structure and adapts to the circumference of different parts of the human body, such as... Figure 2-4 As shown, the shoulder straps are type A, the elbow straps are type B, the waist straps are type C, and the wrist straps, thigh straps, calf straps, and ankle straps are all type D. Among these:

[0035] Type A, Type B and Type C straps can have a storage pocket on the back to hold the vibration module, and the elastic band can make the vibration module 3 fit the limb as closely as possible.

[0036] And / or, the D-type strap can use a three-fold buckle 4, with the vibration module 3 located at the buckle 4, so that the vibration module 3 fits the limb better and improves the accuracy of detection;

[0037] And / or, the straps 2 can all be elastic straps, with Velcro at both ends, so that the straps 2 can fit well on the limbs, while the limbs can feel the vibration generated by the vibration motor 32, and the soft strap material does not affect the movement of the limbs.

[0038] And / or, there can be one waist strap and two of each of the other straps, so in specific implementation, as follows: Figure 2-3 As shown, it can include a total of 13 straps: shoulder straps ×2, elbow straps ×2, wrist straps ×2, waist straps ×1, thigh straps ×2, calf straps ×2, and ankle straps ×2. When using it, you can wear only the straps for the limbs involved in the movement, or you can wear all the straps as needed.

[0039] like Figure 1As shown, the vibration module 3 may also include a sensor 33 connected to its internal control unit 31 for sensing limb movement. The sensor 33 primarily senses whether the trainee's limbs are moving, and is preferably a (triaxial) accelerometer. When the accelerometer of the corresponding strap 2 senses a change in acceleration, the signal is transmitted to the main controller 1 via the control unit 31. The main controller 1 can control the vibration motor 32 in the next strap 2 to start vibrating, or record the movement sequence and duration of various parts of the trainee's body for use in standardizing movements. The frequency at which the accelerometer collects data can be flexibly set as needed, for example, 15Hz.

[0040] In this embodiment of the invention, the main controller 1 can be various mobile terminals, such as mobile phones, tablets, and other smart mobile devices, which receive and transmit signals to the control unit 31 in the vibration module 3 via wireless communication. The mobile terminal can provide an operating interface for the trainee to select the sports movements they want to learn. Then, the mobile terminal controls the vibration motor 32 in the corresponding strap 2 to vibrate according to the training movements selected by the trainee.

[0041] On the other hand, embodiments of the present invention provide a method for using the above-mentioned action learning assistive device, the method of use including a method for assisting in learning actions, such as... Figure 5 As shown, the method for assisting learning actions includes:

[0042] Step 101: The trainee puts on the corresponding straps for the body parts according to the movements they need to learn;

[0043] In this step, depending on the different learning movements, the trainee can wear only the straps for the limbs involved in the movement, or wear all the straps. The learning movements can be pre-selected and set on the main controller.

[0044] Step 102: The trainee begins the exercise. The main controller controls the straps on different parts of the body to vibrate sequentially according to the order of force exertion, so as to remind the trainee to exercise the corresponding parts of the body.

[0045] The method of using the motion learning assistive device in this embodiment of the invention is as follows: after the trainee puts on the straps and starts practicing the movements, the main controller controls the straps of different parts of the body to vibrate in sequence according to the order of force exertion of the movements (specifically, the main controller controls the vibration motor of the corresponding body through the control unit in each strap), thereby reminding the trainee to move the corresponding parts of the body, which can accelerate the trainee's motion learning process and improve the efficiency of motion learning.

[0046] In one embodiment of the present invention, step 102 may include:

[0047] Step 1021: For the first part of the strap in the sequence of force exertion, after the main controller receives the trainee's instruction to start the exercise, it directly controls the strap to vibrate or controls the strap to vibrate after a preset waiting time.

[0048] In this step, the preset waiting time can be flexibly set as needed, such as 1 second, 2 seconds, etc.

[0049] And / or, step 1021': For the straps of the parts other than the first part in the action force sequence, the main controller controls the straps of the next part to vibrate after controlling the vibration of the strap of the previous part in sequence, after a preset interval time.

[0050] In this step, the preset interval time can be obtained by statistically analyzing the interval time of different body parts' movements / force exertion for different actions.

[0051] And / or, step 1021”: For the straps of the parts other than the first part in the action force sequence, after the main controller learns from the sensor that the previous part has moved, it controls the straps of the next part to vibrate after a preset interval.

[0052] In this step, the preset interval time can be obtained by statistically analyzing the interval time of different body parts' movements / force exertion for different actions. Furthermore, in this step, the vibration of the straps for the next body part is controlled only after the sensor detects that the previous body part has moved, thus reminding the trainee to move the next body part, resulting in better movement learning effectiveness. Therefore, the control flow of the movement learning assistance device in this embodiment of the invention can be as follows: Figure 6 As shown.

[0053] Preferably, when the data collected by the sensor shows an acceleration peak greater than a preset threshold within a preset time period (starting from when the main controller controls the vibration of the strap of the corresponding part of the sensor, the preset time can be flexibly set as needed, such as 0.2s, 0.5s, 1s, etc.), it is determined that the (body) part corresponding to the sensor has moved / exerted force. At this time, the main controller then controls the strap of the next (body) part to vibrate after a preset interval.

[0054] The following is an example illustrating the usage of the motion learning assistance device according to an embodiment of the present invention:

[0055] Take the tennis serve as an example:

[0056] The tennis serve is a whipping motion of the upper limbs. The serve consists of three parts: the whipping motion of the upper limbs, the push-off of the lower limbs, and the rotation of the body. Therefore, coordination between the upper and lower limbs and a reasonable rhythm are fundamental to a high-quality serve. Viewing the human body as a chain of motion, the movement of the limbs in the serve exhibits a sequential acceleration from proximal to distal segments, and the speed of each braking segment also increases sequentially from proximal to distal, ultimately forming the whipping motion.

[0057] In tennis serves, the power of the serve does not rely on explosive force generated by the torso and arms; rather, good serve power primarily comes from the flexion and extension of the knee during leg movements. In sports injuries, athletes utilize the force between the torso and upper limbs to move the upper arm to its maximum external rotation position, thus requiring a relatively small internal rotator torque to resist external rotation. Athletes with less leg power primarily achieve maximum external rotation of the upper arm through external rotator muscles, thus requiring a higher internal rotator torque to resist upper arm rotation. Athletes who contribute less leg power also have a higher cubitus varus torque at the moment of maximum upper arm external rotation, making them more prone to injury to the cubitus varus muscles.

[0058] In the tennis serve, the sequence of force application is as follows: lower limb extension—torso twist—upper arm raising and flexion—forearm extension and internal rotation—upper arm internal rotation—hand flexion at the wrist joint. This series of movements from bottom to top gives the racket the speed to serve. The coordinated action of various limbs in the body, following a certain sequence, ultimately completes the shot smoothly.

[0059] The study of the power generation sequence of the main body segments revealed the following order: right knee—left knee—left hip—right hip—right elbow—right wrist. The detailed power generation process for the entire serve is: leg push-off—hip rotation—body rotation—arm rotation around the shoulder—elbow extension—forearm external rotation—wrist rotation—follow-through and landing foot. This power generation sequence allows for seamless connection between the various body segments in the serve, achieving a high-speed serve.

[0060] Therefore, based on the force sequence of a tennis serve, the vibration sequence of the trainee's body points is: right thigh strap—left thigh strap—waist strap—right elbow strap—right wrist strap. This embodiment follows the order of vibration first, then sensation.

[0061] The main controller controls the vibration of the straps on different parts of the body. The right thigh strap vibrates first; once the accelerometer detects the movement, it transmits the information to the main controller. The main controller then controls the vibration motors on the next strap to begin vibrating, and so on. This primarily serves to remind the limb to move. The trainee understands the sequence of movements based on the order of the strap vibrations.

[0062] In this embodiment, the vibration time of the right knee strap is set to zero, the time sensing frequency is 0.01s, and the sensing time of the strap accelerometer is shown in Table 1 below (the range in parentheses is the range of addition or subtraction of the sensing time, which is the range of movement time of various parts of the body in the standard movement mentioned later):

[0063] Table 1

[0064] Strap area Experiencing time (range plus or minus) (s) Right thigh bandage 0.03(0.15) Left thigh bandage 0.93(0.12) Waist strap 0.08(0.02) Right elbow bandage 0.05(0.01) Right wrist strap 0.05(0.01)

[0065] Taking the full swing of golf as an example:

[0066] The golf swing is a rotational movement around the body's longitudinal axis, which runs from the head through the center of the body. Using this axis as a center, the swing involves the arms, hands, shoulders, waist, and lower limbs in a full rotation, resulting in a relatively uniform large arc in the swing trajectory. Technical requirements are specified for each phase of the swing: the effect of the body curling and extending, which can be interpreted as the process of forming and uncoiling a spiral; the transfer of force within the body; and a consistent rhythm and speed throughout the swing.

[0067] In terms of major joints, the backswing phase of a golf swing is characterized by the arms leading the shoulders, and the shoulders leading the hips. The downswing phase is characterized by the lower limbs leading the torso, and the torso leading the upper limbs in a sequential motion. This is mainly achieved through the movement of the two major joints of the human body, the shoulder joint and the hip joint, around the spine. Before the hip and shoulder rotate together towards the closed position (the point of impact), a rotation is formed with the spine as the central axis, and the shoulder and hip joints move in opposite directions. This brief movement of the shoulder and hip in opposite directions causes the hip axis to extend beyond the shoulder axis, and the torso adopts a counter-spiral shape. Some torso muscles tighten as a result, generating significant elastic potential energy. This accumulates energy for the subsequent torso rotation and the whipping motion of the impact swing, and prepares for energy transfer.

[0068] During a golf swing, the sequence of force exerted by different body parts is: pelvis—chest—forearm—club. When the sequence of muscle and joint movements changes, it not only affects ball speed but also increases the risk of injury. Breaking down the full swing into its sequence, the backswing phase is: arms—shoulder—hip—lower limbs; the downswing phase is: lower limbs—hip—torso—upper limbs—club. The full golf swing involves a "whipping" motion where the speed of the limb movements increases sequentially to achieve end-of-swing speed.

[0069] Based on the power generation sequence of a golf swing, the vibration sequence of the trainee's body points is as follows: Backswing phase: wrist strap—elbow strap—shoulder strap—waist strap—thigh strap; Downswing phase: calf strap—thigh strap—waist strap—shoulder strap—elbow strap—wrist strap.

[0070] The main controller controls the vibration of the straps at different locations. The wrist strap vibrates first, and once the accelerometer detects the movement, it transmits the motion data to the main controller. The main controller then controls the vibration motor of the next strap to start vibrating, and so on. Its main function is to remind the limb to move.

[0071] In this embodiment, the vibration time of the wrist strap is set to zero, the time sensing frequency is 0.01s, and the sensing time of the strap acceleration sensor is shown in Table 2 below:

[0072] Table 2

[0073]

[0074] Take baseball pitching as an example:

[0075] Baseball pitching mainly consists of: the preparation phase, the lead foot touchdown phase, the upper limb swing phase, the upper limb acceleration phase, the upper limb deceleration phase, and the follow-through phase.

[0076] The preparatory phase marks the beginning of the throwing motion. Hands are in the starting position, feet are on the ground in a relaxed posture. The lead foot slowly rises, while the supporting foot maintains balance. The upper body movement remains relatively unchanged, and the body's center of gravity remains balanced. After the knee reaches its highest point, the lead foot touches the ground, and the lead foot begins to step forward. The supporting foot transitions from maintaining balance to pushing forward, and the pitching hand begins to horizontally abduct, extending the shoulder joint to its maximum. The body's center of gravity begins to shift forward, culminating in the lead foot touching the ground with the toes pointing forward and the shoulder joint on the throwing side abducted at 90°. After the lead foot touches the ground, the upper body swing begins, with the torso and pelvis rotating forward. The shoulder joint begins to externally rotate, and the center of gravity continues to shift forward until the torso is facing forward and the shoulder joint reaches its maximum external rotation angle, ending the upper body swing. The upper limb acceleration phase begins, approximately 80% of the throwing motion. From the shoulder joint's maximum external rotation angle, internal rotation begins, simultaneously the elbow joint extends, and the upper torso leans forward. By the end of the upper limb acceleration phase, the maximum internal rotation velocity of the shoulder joint reaches 7600° / s, while the maximum extension velocity of the elbow joint reaches 2400° / s. After the ball is released, the upper limb deceleration phase begins, the movement slows down, the upper torso continues to lean forward, the shoulder joint reaches its maximum internal rotation angle, the elbow joint continues to extend, and the body's center of gravity shifts to the leading foot. In the final follow-through phase, the shoulder joint continues to internally rotate and decelerate, the center of gravity is fully transferred to the leading foot until the entire throwing motion is completed.

[0077] Based on the force exertion sequence of a baseball pitch, the vibration sequence of the trainee's body points is as follows: left thigh strap — (after feeling the thigh stop rising) — left thigh strap — wrist strap — left thigh strap — right shoulder strap — right elbow strap — right wrist strap.

[0078] The main controller controls the vibration of the straps on different parts of the body. The left thigh strap vibrates first, and after the accelerometer detects the movement, it transmits the motion data to the main controller. The main controller then controls the vibration motor of the next strap to start vibrating, and so on. Its main function is to remind the limbs to move.

[0079] In this embodiment, the vibration time of the left thigh strap is set to zero, the time sensing frequency is 0.01s, and the sensing time of the strap acceleration sensor is shown in Table 3 below:

[0080] Table 3

[0081]

[0082] In this embodiment of the invention, most of the phased movements can be learned and trained using this invention. The learnable movements include, but are not limited to, swimming, some track and field events, badminton, canoeing, baseball, basketball, fencing, football, and many other sports.

[0083] Furthermore, embodiments of the present invention provide a method for using the aforementioned motion learning assistance device, the method including methods for assisting in the standardization of movements, such as... Figure 7 As shown, the method for assisting in standardizing actions includes:

[0084] Step 201: The trainee puts on the straps for each part of the body and chooses the movements they want to perform correctly;

[0085] In this step, the trainee can wear all 13 straps mentioned above. Proper movements can be pre-selected and set on the main controller.

[0086] Step 202: The trainee performs the movement exercise, and the main controller records the movement sequence and movement time of various parts of the trainee's body through sensors;

[0087] In this step, during the movement, the main controller can divide the action into n stages according to different body parts, with T as the total time and the time of each stage being t1, t2, ..., tn. Based on the length of time, the movement time / duration of that part is detected.

[0088] Step 203: The main controller compares the movement sequence and time of each part of the trainee's body with the movement sequence and time of each part of the body in the standard movement;

[0089] In this step, the sequence of movements and the duration of movements are compared separately. The sequence of movements reflects the order of force application, while the duration of movements reflects the standardization of the action / force application.

[0090] When the accelerometer on the limb strap detects that the limb movement time is within the system's specified time range, it indicates that the force exertion duration for that part has reached the average level. If the movement time is less than the specified time range, it indicates that the force exertion duration for that part is too short; if it is greater than the specified time range, it indicates that the force exertion duration for that part is too long. The system's specified time range only plays a certain role in the initial learning stage and can be used to standardize the limb coordination and the force exertion magnitude of different parts of the body.

[0091] Step 204: The main controller displays the comparison results to the trainee.

[0092] In this step, the main controller can display the comparison results (including the incorrect body parts and movement sequence in the movement) to the trainee through the display interface, and can also provide corresponding explanations and suggestions for movement improvement to the trainee so that the trainee can correct the movement according to the errors.

[0093] The method of using the motion learning assistance device according to this invention involves the trainee first wearing straps to various parts of their body and selecting the desired movement. The trainee then practices the movement, and the main controller records the movement sequence and time of each body part using sensors. The main controller then compares the movement sequence and time of the trainee's body parts with those of a standard movement. Finally, the main controller displays the comparison results to the trainee. In this way, the main controller in this embodiment can display incorrect body parts and movement sequences in the trainee's movements, allowing the trainee to correct the errors and thus accelerating the motion learning process and improving learning efficiency.

[0094] In one embodiment of the present invention, step 203 may further include:

[0095] The main controller calculates the ratio of the movement time of different parts of the trainee's body and compares it with the ratio of the movement time of different parts of the body in the standard movement.

[0096] Considering that simply comparing the movement time of each body part with that of the standard movement may not be sufficient to evaluate the standardization of the movement, this embodiment uses the ratio of the movement time of each body part, such as the ratio of the movement time of the calf to that of the waist, the ratio of the movement time of the thigh to that of the waist, the ratio of the sum of the movement time of the calf and thigh to that of the waist, the ratio of the movement time of the calf to that of the shoulder, the ratio of the movement time of the thigh to that of the shoulder, and the ratio of the sum of the movement time of the calf and thigh to that of the shoulder. By combining the ratio of movement time, the standardization of the trainee's movement can be better judged. These indicators are particularly effective in solving the problem of inefficient lower limb force exertion.

[0097] In summary, the motion learning aid device and its usage method according to the embodiments of the present invention are used for trainees who need to learn or standardize motions to learn motions. Trainees can self-correct without a coach, correcting the sequence of motions and the timing (magnitude) of force exertion. Furthermore, the present invention is applicable to everyone, improving motion coordination, accelerating the learning process, and increasing motion learning efficiency.

[0098] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
