Fig. 1 is a schematic flow chart of a method for guiding center of gravity shifting training according to an embodiment of the present invention.

As shown in fig. 1, the method includes:

s100, obtaining a pelvis inclination angle and a lower limb inclination angle;

s200, calculating an actual gravity center value according to the pelvis inclination angle, the lower limb inclination angle and a preset gravity center function;

and S300, outputting prompt information according to the actual gravity center value.

The prompt information is used for guiding the user to carry out gravity center shifting training.

In the embodiment, the actual gravity center value is calculated by acquiring the pelvis inclination angle and the lower limb inclination angle and according to the pelvis inclination angle, the lower limb inclination angle and the preset gravity center function, so that the human body weight and heart transfer is monitored. And outputting prompt information according to the calculated actual gravity center value to guide the user to carry out gravity center transfer training so that the actual gravity center value is moved to the target gravity center value. Because the pelvis is closest to the gravity center position of the human body, the correct motion of the pelvis is ensured to be more in accordance with the health of the human body, the gravity center transfer of the human body is indirectly monitored by acquiring the pelvis inclination angle and the lower limb inclination angle, and the calculated actual gravity center value can be more accurate, so that an accurate training mode is provided for a user.

In some embodiments, the above-described method for guiding the center of gravity shifting training may be implemented by a processor, a controller, or the like. Taking the processor as an example, the center-of-gravity function is stored in the processor in advance and used for calculating the actual center-of-gravity value. The above steps are explained in detail below:

step S100: the pelvic tilt angle and the lower limb tilt angle are obtained. Referring to fig. 2, a pelvic tilt angle α can be acquired by detecting a posture sensor placed at a pelvis of a human body; the lower limb inclination angle beta can be obtained by detecting through a posture sensor placed on the lower limb of the human body or detecting through an angle sensor arranged on the hip joint.

Step S200: and calculating an actual gravity center value according to the pelvis inclination angle, the lower limb inclination angle and a preset gravity center function. If the obtained pelvis inclination angle is alpha, the lower limb inclination angle is beta and the pre-stored gravity function is f, the pelvis inclination angle alpha and the lower limb inclination angle beta are substituted into the gravity function f to calculate the current actual gravity center value of the human body.

Step S300: and outputting prompt information according to the actual gravity center value. The prompt information is used for guiding the user to carry out gravity center transfer training so that the actual gravity center value is moved to the target gravity center value. If the center of gravity of the human body shifts, the calculated actual center of gravity value does not match the target center of gravity value. The processor outputs prompt information according to the actual gravity center value to guide the user to train, so that the aim of moving the actual gravity center value to the target gravity center value is fulfilled.

In some embodiments, the prompt information may be a motion trajectory signal, the processor generates a motion trajectory signal for guiding the user to train according to the actual gravity center value, outputs the motion trajectory signal to the display screen to display, and the user trains according to the displayed motion trajectory; the prompt information may also be a voice signal, the processor generates a voice signal for guiding the user to train according to the actual gravity center value, outputs the voice signal to the player for playing, and the user trains according to the played voice, for example, if the calculated actual gravity center value is left relative to the target gravity center value, the voice similar to "please slowly move the pelvis or the lower limbs right" is played, and the user is guided to move the pelvis or the lower limbs right, so as to complete the gravity center transfer training.

It should be noted here that if the actual center of gravity value is calculated only according to the pelvis inclination angle α and the lower limb inclination angle β, the waist rotation angle is considered to be zero approximately, and at this time, the user needs to be prompted not to deflect the waist as much as possible to ensure that the calculated actual center of gravity value is more accurate.

In some embodiments, as shown in fig. 3, the method for guiding the training of center of gravity shifting further comprises:

s400, acquiring a waist corner;

and S500, calculating an actual gravity center value according to the waist corner, the lower limb inclination angle and a preset gravity center function.

In some embodiments, referring to fig. 2, the waist rotation angle γ may also be obtained, and the actual barycentric value is calculated according to the waist rotation angle γ, the lower limb inclination angle β and the preset barycentric function f, so as to monitor the human weight-heart shift. And outputting prompt information according to the calculated actual gravity center value to guide the user to train so that the actual gravity center value moves to the target gravity center value. Because the waist is nearer apart from human focus position, guarantee that the correct motion of waist accords with human health more, consequently come indirect to human focus shift to monitor through acquireing waist corner and low limbs inclination, can also make the actual focus value of calculation more accurate to provide accurate training mode for the user.

It should be noted here that if the actual center of gravity is calculated from only the waist rotation angle γ and the lower limb inclination angle β, the pelvis inclination angle is assumed to be zero by approximation. Because the pelvis and the lower limbs are connected into a whole, the user needs to be prompted to ensure that the lengths of the lower limbs on the two sides are approximately equal to each other, namely the two legs are not bent or the bending degrees are the same, and the calculated actual gravity center value can be ensured to be more accurate.

In some embodiments, the method for guiding the training of the center of gravity shifting further comprises:

and calculating an actual gravity center value according to the pelvis inclination angle, the waist rotation angle, the lower limb inclination angle and a preset gravity center function.

In some embodiments, in order to make the calculated actual barycentric value more accurate, the pelvic tilt angle α, the lumbar rotation angle γ, and the lower limb tilt angle β need to be acquired simultaneously. Referring to fig. 2, a schematic diagram of posture change of a human body is shown. Wherein the solid line represents one posture of the human body and the dotted line represents another posture of the human body. In the process of changing the posture of the human body from the solid line to the dotted line, the gravity center of the human body is shifted. The body part in the figure includes left lower limb, right lower limb, hip, pelvis (pelvis between two hips), waist and upper body. L1 is the distance from the hip to the left foot in the dotted line posture, L2 is the distance from the center of the pelvis to the hip in the dotted line posture, L3 is the distance from the pelvis to the waist in the dotted line posture, L4 is the upper body distance in the dotted line posture, α is the angle between the pelvis in the dotted line posture and the horizontal direction (i.e., the pelvis tilt angle), β is the angle between the left/right lower limbs in the dotted line posture and the vertical direction (i.e., the lower limb tilt angle), and γ is the angle between the waist and the upper body in the dotted line posture (i.e., the waist rotation angle). How to calculate the actual barycentric value during the barycentric transfer will be described below with reference to fig. 2:

for ease of understanding, examples are not limited thereto: defining the calculation result of the gravity function f as 0, and indicating that the gravity is completely positioned at the left foot; the result of the center of gravity function f is 1, indicating that the center of gravity is completely in the right foot. As can be seen from fig. 4, the horizontal distance P1= L1 × sin (β) + L2 × cos (α) from the center of the pelvis to the left foot; horizontal distance P2= P1+ L3 × sin (α) of the waist from the left foot; the horizontal distance P3= P2+ L4 × sin (α + γ) of the upper body center of gravity from the left foot. The weight factors defining the center of gravity as pelvis, waist and upper body are k1, k2 and k3, respectively, the center of gravity function f = (k 1 × P1+ k2 × P2+ k3 × P3)/(2 × l 2). Where 2 × l2 represents the distance from the left foot to the right foot. Since the body dimensions are scaled, i.e., L1, L2, L3 and L4, all physical dimensions are eliminated, the center of gravity function

f＝(k1*L1*sin(β)+k1*L2*cos(α)+k2*P1+k2*L3*sin(α)+k3*P2+k3*L4*sin(α+γ))/(2*L2)＝x1*sin(β)+x2*cos(α)+x3*sin(α)+x4*sin(α+γ)

The total can be expressed as f (α, β, γ), and the actual center of gravity value can be calculated by substituting the pelvis tilt angle α, the waist rotation angle γ, and the lower limb tilt angle β into the center of gravity function f (α, β, γ). If the actual gravity center value is 0, the gravity center is completely positioned at the left foot; if the actual gravity center value is 1, the gravity center is completely positioned at the right foot; if the actual gravity center value is 0-0.5, the gravity center is deviated to the left; if the actual gravity center value is 0.5-1, the gravity center is shifted to the right.

It should be noted here that the human body posture shown in fig. 2 is a posture of a human coronal plane, and the center of gravity of the human coronal plane is shifted in the left-right direction. And the center of gravity of the human sagittal plane moves in the front-back direction, so if the user wants to train the center of gravity transfer of the human sagittal plane, the user can step forward a little at the beginning of the training, and the steps of the subsequent guidance method for center of gravity transfer training are consistent with the steps of the coronal plane.

In some embodiments, before calculating the actual barycentric value according to the pelvis inclination angle, the waist rotation angle, the lower limb inclination angle and the preset barycentric function, the method for guiding the barycentric transfer training further comprises:

the pelvic tilt angle and the lumbar rotation angle are range-detected.

Since the pelvic tilt angle α and the lumbar rotation angle γ do not change or change within an appropriate range when the human body is in a certain posture. For example, when a person normally walks, the pelvic tilt angle α and the lumbar rotation angle γ are uniformly changed within a proper range. Therefore, before the actual gravity center value is calculated, the range of the pelvis inclination angle alpha and the waist rotation angle gamma is detected, and the error of the calculation result caused by the error of the sensor can be effectively avoided.

It will be appreciated that the detection range may be adjusted for specific part training. For example, in the walking ability training, the detection ranges of the pelvic tilt angle α and the lumbar rotation angle γ can be set to 10 to 20 degrees without excessively tilting the pelvis and excessively tilting the waist.

In some embodiments, as shown in fig. 4, the method for guiding the training of center of gravity shifting further includes:

s600, receiving a user instruction;

and S700, adjusting a preset gravity function according to a user instruction.

When a user wants to train a specific part, a user instruction can be input according to the user's own needs, and after receiving the user instruction, the processor adjusts the preset gravity function f according to the user instruction, mainly adjusts weight factors of the pelvis, the waist and the upper body. For example, when the user wants to train the waist, the user inputs a user instruction for increasing the weight factor of the waist, and after receiving the user instruction, the processor increases the weight factor k2 of the waist in the calculation formula of the center-of-gravity function f, so that the user mainly moves the waist to change the center of gravity, thereby realizing the purpose of training the waist of the user intensively.

In some embodiments, the user input of the user command may be implemented by voice input, panel input, key operation input, and the like.
