1 is a schematic block diagram of a motor skill training apparatus according to an embodiment of the present invention.

Referring to FIG. 1, a movement pattern measuring device 2 measures a movement pattern of a learner's body 1, and the output thereof is input to a corrected muscle activity calculating device 3. The output of the desired exercise pattern storage device 4 in which the desired exercise pattern, which is an ideal exercise pattern, is stored in advance is input to the other input of the corrected muscle activity calculation device 3. Modified muscle activity calculator 3
Compares the input motion pattern with the target motion pattern, calculates the correction direction of the motion pattern, and inputs the corrected muscle activity, which is the output, to the stimulation time pattern generator 5.
The stimulation time pattern generator 5 generates a stimulation time pattern based on the input corrected muscle activity and inputs it to the stimulation controller 6. When the control signal output from the stimulation controller 6 is input to the vibrator and the stimulation electrode 7, the vibrator and the stimulation electrode 7 are driven, and the tension of the muscle of the body 1 of the exerciser increases or decreases.

FIG. 2 is a flow chart for explaining the operation of the motor skill training device according to one embodiment of the present invention. Next, the operation of FIG. 1 will be described in detail with reference to FIG.

In step S (abbreviated as S in the drawing) 1, a learner who is trained in motor skills exercises body 1. In step S2, the motion pattern generated by the motion of the body 1 is measured by the motion pattern measuring device 2
To measure. In step S3, the target exercise pattern previously stored in the desired exercise pattern storage device 4, that is, the ideal exercise pattern to be exercised when the learner acquires the exercise skill is read out.

In step S4, the corrected muscle activity calculation device 3 compares the motion pattern input by the motion pattern measurement device 2 with the target motion pattern input by the target motion pattern storage device 4 to obtain an ideal target motion pattern. Calculate the increase or decrease in tension of multiple muscles required to bring the movement pattern closer to. The specific operation of the modified muscle activity level calculation device 3 is, for example, that the motion pattern measured by the motion pattern measurement device 2 and the target motion pattern stored in the target motion pattern storage device 4 are both expressed by myoelectric signals. If the exercise pattern is a desired exercise pattern, the difference between the two exercise patterns is simply calculated, and the calculation result is used as the corrected muscle activity.

On the other hand, if the motion pattern and the desired motion pattern are represented by joint angles, the corrected muscle activity calculator 3 converts the joint angle error into a joint torque error using the inverse dynamics equation. Further, the error of the joint torque is converted into an error of the muscle tension by using the transposed matrix of the matrix created by the moment arms of each muscle. The modified muscle activity calculation device 3 in this case is, for example, a body dynamics model including a cyclically coupled neural circuit that is learned by using error back propagation. Also, the body 1 whose movement pattern is in three-dimensional Cartesian coordinates
, The corrected muscle activity calculation device 3 first converts the position of each portion into a motion pattern represented by the joint angle by using the inverse kinematics equation, and then the method described above. Is converted into an error of muscle tension using.

In step S5, the stimulation time pattern generator 5 performs stimulation based on the corrected muscle activity level input by the corrected muscle activity level calculation device 3 at which timing while the learner's body 1 is in motion. Generate a stimulation time pattern of what to give. In step S6, the stimulation controller 6 inputs a control signal for controlling stimulation with the input stimulation time pattern to the vibrator and stimulation electrode 7. In step S7, by driving the vibrator and the stimulation electrode 7, stimulation for increasing or decreasing the muscle tension is applied to the learner's body 1. In step S8, it is determined whether or not the operation of the device may be terminated. For this determination, for example, a target motion pattern that is a motion pattern when the learner has acquired motor skills without giving a stimulus. The determination may be made depending on whether or not

FIG. 3 is a diagram showing the result of correction of the motion pattern without applying mechanical vibration stimulation to the learner's body. In particular, FIG. 3 (a), FIG. 3 (b) and FIG. 3 ( c)
Stimulated the triceps with a vibrator for about 300 ms in the latter half of the extension of the right-hand elbow joint, in the second half of the flexion of the left-hand elbow joint, and at the end of the extension of the right-hand elbow joint. It is the figure which showed the result. The horizontal axis is a subject (M
K) is the number of stimulations given, and the vertical axis is the rotation angle of the elbow joint at the end of exercise. Further, □ indicates that the target was visually stimulated without stimulation, ● indicates that the target was not stimulated without vision, and ○ indicates that the target was not stimulated. The case where the target is stimulated without sight is shown.

As shown in FIG. 3 (a), when stimulation is given in the latter half of the extension exercise, not only does the movement increase with respect to the target when stimulation is given but also no stimulation is given. Also, it can be seen that the influence has come out and the exercise is getting bigger. Furthermore, in the drawing, 1day, 2day
It can also be seen that the effects are exhibited even when the exercise is performed without giving a stimulus after 1 day and 2 days indicated by s, and it is corrected for a long time. On the other hand, as shown in FIG. 3 (b), when stimulation is given in the latter half of the flexion movement, not only does the movement decrease with respect to the target when stimulation is given but also no stimulation is given. Also, it can be seen that the influence has come out and the exercise has become smaller. Also, FIG.
As shown in (c), when the stimulation is given at a timing to be given, not immediately before the end of the exercise, that is, when the stimulation is not given in the latter half of the exercise, the effect of the stimulation is long-term. You can see that it does not remain. In this way, by giving a stimulus at a timing at which the learner should acquire the motor skill, the learner can execute an ideal exercise without giving a stimulus.

[0016]

As described above, according to the present invention, a stimulus that measures a motion pattern from the motion of a learner, compares the motion pattern with an ideal motion pattern, and corrects the error. By giving to the learner at a specific timing, not only can the learner perform long-term exercises that correspond to the ideal target exercise pattern, but also during training to acquire motor skills. In, the motor skills can be acquired in a short time without any special effort or pain.
