The control unit 150 can calculate the center of gravity based on the information measured from the weight sensors 110a to 110d of the foot plate 110 and can perform the game and balance evaluation of the non-trainee based on the calculated center of gravity.

The control unit 150 may be embedded in the foot plate 110. At this time, a wireless communication module for wireless communication with the controller 150 and the display unit 132 or the input unit 140 may be provided. Alternatively, the control unit 150 can perform communication with the display unit 132 or the input unit in a wired communication manner.

Here, the controller 150 calculates the two-directional force and the total force measured by the weight sensors 110a to 110d to calculate the positions of the trainee trainees, calculates the compartments corresponding to the calculated positions, The center of gravity of the trainee is calculated by calculating the distance, and the item is acquired and scored in the running game in accordance with the calculation result. The same item is graded according to the calculation result, and the balance state of the trainee is evaluated have. The controller 150 may include a center of gravity calculator 152, a game controller 154, and an evaluation processor 156.

The center of gravity calculating section 152 is for calculating the center of gravity corresponding to the motion of the lower limb trainer for use in the game, and includes a load calculating section 152a, a position calculating section 152b, a section calculating section 152c, And a distance calculating unit 152d.

The load calculating unit 152a can calculate the loads by converting the measured values of each of the weight sensors 110a to 110d into bi-directional forces such as x and y directions and total force. That is, the load calculating unit 152a can convert the voltage value measured from the weight sensors 110a to 110d into the magnitude of the force.

The position calculating unit 152b can calculate the position of the center of gravity according to the calculated ratio of the bi-directional force and the total force. For example, the position calculating unit 152b may calculate the position of the center of gravity (CoPx, CoPy) according to the following equation:

Figure pat00003

Fi is the force with respect to the x-axis direction of the weight sensor, FiYi is the force with respect to the y-axis direction of the weight sensor, and Fi is the total force of the weight sensor.

That is, the position calculating unit 152b calculates the sum of the total forces Fi for each of the weight sensors 110a to 110d disposed at the four corners of the foot plate 110, the force (Fixi) in the x- the position of the center of gravity according to the magnitude of the sum of the forces Fiyi in the y-axis direction can be calculated as the coordinates in the foot plate 110. [

For example, when the foot plate 110 is composed of 50 cm to -50 cm, the index i is a position indicating the coordinates of the weight sensors 110a to 110d on the foot plate 110, (-50, -50) of the second quadrant (-50,50), index 3 is the third quadrant corner (-50, -50), index 4 is the fourth quadrant corner 50 , -50).

The partition calculating unit 152c can calculate the partition according to the position of the center of gravity (CoPx, CoPy) calculated by the position calculating unit 152b and a plurality of thresholds that divide nine compartments.

For example, the compartment calculating unit 152c may calculate the compartments in the footing 110 as shown in FIG. 2 by comparing the calculated positions of the center of gravity (CoPx, CoPy) with the sizes of the plurality of thresholds . Here, the conditions for calculating the corresponding compartment are determined according to the sizes of the plurality of threshold values as shown in FIG.

Here, the position of the center of gravity (CoPx, CoPy) is favorable to the x-axis and y-axis coordinates in the foot plate 110, and the first threshold value (- Xthr ) And the second threshold value X thr is a position spaced a certain distance from the origin 0,0 of the foot plate 110 to the right. The third threshold value Y thr is a position spaced forward by a distance from the origin 0,0 of the foot plate 110 and the fourth threshold value Y thr is a position at the origin 0 of the foot plate 110 , 0) (see Fig. 5).

If the value of the center of gravity position CoPx is smaller than the first threshold value -X thr and the value of the center of gravity position CoPy is larger than the third threshold value Y thr , And if the center of gravity position CoPx is greater than the second threshold value X thr and the center of gravity position CoPy is greater than the third threshold value Y thr ,

Similarly, if the value of the center of gravity position CoPx is smaller than the first threshold value -X thr and the value of the center of gravity position CoPy is smaller than the fourth threshold value -Y thr If the value of the center of gravity position CoPx is greater than the second threshold value X thr and the value of the center of gravity position CoPy is less than the fourth threshold value -Y thr , Can be calculated.

If the absolute value of the center-of-gravity position CoPx is smaller than the second threshold value X thr and the center-of-gravity position CoPy is larger than the third threshold value Y thr , If the absolute value of the center of gravity position CoPx is smaller than the second threshold value X thr and the center of gravity position CoPy is smaller than the fourth threshold value -Y thr , It can be calculated as a compartment. At this time, the compartment calculation unit 152c is the center of the foot plate 110, and the fifth compartment, which is the reference point, can be set as default.

The movement distance calculation unit 152d can calculate the movement distance of the center of gravity of the position of the center of gravity (CoPx, CoPy) calculated by the position calculation unit 152b. For example, the movement distance calculating unit 152d calculates the distance between the calculated position of the center of gravity (CoPx, CoPy) and the origin (0, 0) of the foot plate as shown in the following equation (3) Can be calculated as the distance d.

Figure pat00004

With such a configuration, the lower body exercise training apparatus 100 using the center-of-gravity movement according to the embodiment of the present invention can calculate the center-of-gravity movement of the under trainer by using only the four weight sensors 110a to 110d.

The game execution unit 154 can execute a game in which the position is selected in accordance with the calculation result by the center of gravity calculation unit 152 to acquire an item. That is, the game execution unit 154 inputs the movement of eight directions (1 to 4, 6 to 9) in the front, rear, left, and right directions about the central compartment (compartment 5) . ≪ / RTI >

For example, as shown in FIG. 4, the game executing unit 154 may select one of the eight items displayed on the right side of the footstep 110 to acquire an item at the lower right end 402 around the reference point 401 When the center of gravity is changed from the fifth division to the ninth division, it is possible to select the item 402 by receiving it. At this time, the selected item 403 can be displayed on the left screen.

In addition, the game execution unit 154 scales an item to display a score of the item or an accumulated score. That is, even when the same item is acquired, the game execution unit 154 can assign a differentiated score according to the calculated movement distance.

For example, even if the same section is selected in the footstep 110, the game execution section 154 can give a higher score toward the center of the corresponding section.

Alternatively, the game executing section 154 can adjust the differential interval for scoring the game according to the evaluation result of the evaluation processing section 156 as described later. In other words, the game executing unit 154 can differentiate the score so as to select the accurate position to improve the cognitive ability, or to increase the shift distance of the selected position so as to improve the balance or the exercise capacity.

As described above, the lower body exercise training apparatus 100 using the center-of-gravity movement according to an embodiment of the present invention not only notifies the user of his / her condition easily by the scoring difference, The exercise can be promoted by inducing the exercise of the trainee.

The evaluation processing unit 156 can evaluate the balance state of the trainee after the game ends. 6A, the evaluation processing unit 156 guides the foot trainer to place the foot 601 in any two of nine segments in the footing 110, The average value can be calculated by repeatedly measuring the center of gravity a certain number of times.

6B, the evaluation processing unit 156 calculates the left-right balance ratio 602 according to the moving distance of the center of gravity according to the distance from the origin of the footing 110, and displays the balance ratio 602 on the display unit 132 Can be processed.

For example, in the case where the trainee is placed in the fourth compartment and the sixth compartment respectively, if the left and right balances are uniform, the center of gravity is positioned on or near the first threshold value (-X thr ) In this case, the center of gravity is located on the left or right side of the first threshold value ( -Xthr ).

That is, the evaluation processing unit 156 can evaluate the left-right balance state according to the degree of deviation of the distance between the current center-of-gravity position and the origin (0, 0) of the foot 110 as the origin of the center of gravity.

At this time, the evaluation processing unit 156 can calculate the left-right balance ratio according to the moving distance of the center of gravity. For example, when the moving distance of the center of gravity to the origin of the foot plate 110 is larger than the first threshold value (-X thr ), the evaluation processing unit 156 evaluates that the center of gravity is shifted to the left side, Value (- X thr ), it can be estimated that the center of gravity is shifted to the right side. Here, the evaluation processing unit 156 can quantify the degree of deviation according to the magnitude of the moving distance of the center of gravity.

With this configuration, the lower body exercise training apparatus 100 using the center-of-gravity movement according to an embodiment of the present invention calculates the distance of movement of the center of gravity of the underdog trainer while using the minimum weight sensor, The effect of exercise training can be improved by inducing interest in participation in exercise training.

In addition, the lower body exercise training apparatus 100 using the center-of-gravity movement according to an embodiment of the present invention evaluates the post-game balance state of the underprivileged trainee and reflects the posture state in the game differentiation score, At the same time, the disabled trainee can confirm the improvement of the condition, so that it can induce a continued interest as the score is scored high.

In addition, the lower body exercise training apparatus 100 using the center-of-gravity movement according to an embodiment of the present invention uses a minimum weight sensor through an algorithm for partitioning and positioning around the origin of the foot plate, The manufacturing cost can be reduced.

Hereinafter, a method of training a lower body exercise using the center-of-gravity movement of the present invention will be described with reference to FIGS.

As shown in FIG. 7, the lower body exercise training method 700 using the center-of-gravity movement according to an embodiment of the present invention includes an initialization step S701 of calculating an offset in a no-load state, (S702), calculating a center of gravity in the footstool (S703), acquiring an item by position in accordance with the calculation result (S704, S705), and calculating a left-right balance state Evaluating step S706, and adjusting the difference scoring interval (S707).

More specifically, the offset of the no-load state can be calculated and initialized for the four weight sensors 110a to 110d provided at the respective corners of the foot plate 110 (step S701). Here, the foot plate 110 has a rectangular shape and is divided into nine compartments by the compartment line 112. This initialization step may include zeroing of the footplate 110 relative to the weight sensors 110a-110d.

Next, in step S702, the footstep 110 may select a position according to the center of gravity of the trainee to acquire an item, and score the obtained item (step S702). Here, the type of game to be executed is not particularly limited. For example, as shown in Fig. 4, a game in which an item arranged in the upper, lower, left, and right sides around the reference point 401 is selected, At this time, the selection of the position may be determined according to the center of gravity input from the footrest 110. [

Next, the center of gravity corresponding to the motion of the disabled trainee for use in the game being executed can be calculated (step S703). At this time, the calculation of the center of gravity calculates the two-directional force and the total force based on the measured values by the weight sensors 110a to 110d, calculates the position of the underbearer according to the ratio of the force in each direction and the total force , Calculating the segment corresponding to the position, and calculating the moving distance of the center of gravity to calculate the center of gravity of the lower trainee.

8, first, the measured values of each of the weight sensors 110a to 110d can be converted into two-directional forces such as x and y directions and total force to calculate the load S801). At this time, the voltage values measured from the weight sensors 110a to 110d can be converted into the magnitude of the force.

Next, the position of the center of gravity can be calculated according to the calculated ratio of the bi-directional force and the total force (step S802).

The sum of the total forces Fi for each of the weight sensors 110a to 110d disposed at the four corners of the foot plate 110 and the sum of the force in the x axis direction Fixi and the force in the y axis direction Fiyi The position of the center of gravity according to the sum size of the coordinates of the footstep 110 can be calculated. For example, the position of the center of gravity (CoPx, CoPy) can be calculated according to Equation (1).

Next, the compartments can be calculated in accordance with a plurality of threshold values corresponding to the calculated center of gravity positions (CoPx, CoPy) and the partition lines 112 that divide nine compartments of the foot plate 110 (step S803) .

That is, the compartments can be calculated by the pedestal 110 by comparing the calculated positions of the center of gravity (CoPx, CoPy) with the sizes of the plurality of threshold values (± Xhtr , ± Yhtr ). At this time, the conditions for calculating the compartment can be determined as described with reference to Fig.

Next, the movement distance of the center of gravity with respect to the calculated position of the center of gravity (CoPx, CoPy) can be calculated (step S804).

In this case, the distance between the calculated center of gravity position (CoPx, CoPy) and the origin (0, 0) of the foot plate 110 may be calculated as the moving distance d of the center of gravity as shown in Equation (2) have.

Referring again to FIG. 7, an item may be acquired and scored in the game being executed according to the calculation result of step S703 (step S704). At this time, the same item can be graded according to the calculation result, and the obtained score or the missing score can be displayed on the display unit 132. [

More specifically, referring to FIG. 9, the game may be started in a state where it is positioned at the origin (5th division) on the foot plate 110 (step S901).

Next, after confirming the items displayed on the display unit 132, the bottom trainer moves on the foot plate 110 to receive the result calculated in step S703 as a selection of the movement position (step S902).

Next, as shown in FIG. 4, a corresponding item corresponding to the input position may be acquired and a score for the item may be acquired (step S903). At this time, the item can be scored and the score of the item or cumulative score can be displayed.

Here, the score for the item may be differentiated according to the magnitude of the movement distance of the center of gravity calculated for the obtained item. For example, even if the same compartment is selected in the footing 110, the closer to the center of the compartment the higher the score can be given.

Alternatively, the trainee may return 904 to the origin (5th compartment) of footplate 110 to obtain the next item. In other words, in order to improve the exercise amount of the disabled trainee, it is necessary to acquire a specific item and then return to the original position (compartment 5) and acquire the next item.

Referring again to FIG. 7, the balance state of the trainee can be evaluated after the end of the game (step S706). Here, the evaluation is to evaluate the left-right balance state in the upright state of the lower limb trainee.

More specifically, referring to FIG. 10, the measurement position can be displayed through the display unit 132 so as to place the foot of the foot trainer in any two of nine compartments (step S1001).

At this time, the center of gravity measured by the trainee can be repeatedly measured a predetermined number of times to calculate an average value, and the moving distance of the center of gravity according to the distance from the origin (0, 0) of the footstep 110 can be calculated (step S1002 ).

Next, the left-right balance ratio can be calculated according to the calculated moving distance of the center of gravity (step S1003). Here, the right and left balance state can be evaluated according to the degree of deviation of the distance between the current center of gravity position from the origin (0, 0) of the foot plate 110 which is the origin of the center of gravity.

At this time, when the moving distance of the center of gravity with respect to the origin of the foot plate 110 is larger than the first threshold value (-Xthr), it is evaluated that the center of gravity is shifted to the left side. When the distance is smaller than the first threshold value (- Xthr) It can be estimated that the center of gravity is shifted to the right. Here, the degree of deviation can be quantified according to the magnitude of the moving distance of the center of gravity.

Next, the calculated balance ratio can be displayed on the display unit 132 so that the disabled trainee can confirm it (step S1004).

Referring again to FIG. 7, the differential interval for scoring the game can be adjusted according to the evaluation result of step S706 (step S707).

In other words, the score can be differentiated so as to select the correct position to improve the cognitive abilities of the disabled trainee, or to increase the shift distance of the selected position so as to improve balance or athletic performance.

In this way, the method 700 for training the lower body exercise using the center-of-gravity movement according to an embodiment of the present invention calculates the distance of movement of the center of gravity of the underbearer while applying the minimum weight sensor, The effect of exercise training can be improved by inducing interest in exercise training.

In addition, the lower body exercise training method 700 using the center-of-gravity movement according to an embodiment of the present invention evaluates the post-game balance state of the underdeveloped trainee and reflects the state of the under- At the same time, the disabled trainee can confirm the improvement of the condition, so that it can induce a continued interest as the score is scored high.

In addition, the method 700 for training a lower body exercise using the center-of-gravity movement according to an embodiment of the present invention uses a minimum weight sensor through an algorithm for partitioning and positioning around the origin of a foot plate, The manufacturing cost can be reduced.

Such methods may be implemented by a lower body exercise training apparatus 100 using the center-of-gravity movement as shown in FIG. 3, and in particular, may be implemented by a software program that performs these steps, The programs may be stored on a computer readable recording medium or transmitted by a computer data signal coupled with a carrier wave in a transmission medium or a communication network.
