For example, the processor 170 calculates the first walking angle information based on the sensing signal from the motion sensor unit 131 to be activated during the first period, and calculates the first walking angle information based on the sensing signal from the pressure sensor unit 133, The second walking angle information is calculated based on the foot pressure signal from the second walking angle information, and finally, the first walking angle information and the second walking angle information can be calculated.

The processor 170 determines whether or not the time point (corresponding to the RP time in Fig. 2) having the same z-axis position information among the motion information from the motion sensor unit 131 disposed in the insole 100a of Fig. The first walking angle information of the insole 100 can be calculated on the basis of the x and y axis variation amounts during the first time interval between the starting points.

The processor 170 may use the equation 1, 2, and so on during the second period to obtain the second walking angle &thetas; information between the y-axis and the actual traveling direction, Information can be computed.

According to the operation method of the insole of FIG. 8, since the motion sensor unit 131 is activated only during the first period, the power consumption of the battery (not shown) in the power supply unit 190 can be reduced.

In addition, by using the padding information for the first period, the padding information for the second period, and the like, the padding information is finally calculated, thereby improving the accuracy of the padding information.

Similarly, by using the walking angle information for the first period, the walking angle information for the second period, and the like, finally, the accuracy of the walking angle information can be improved by calculating the stride information.

Figures 9A-11 are views referenced in the description of the method of operation of the insole of Figure 8.

9A illustrates an example in which the motion sensor unit 131 calculates the stride D1 during the first period. In particular, the stride D1 is calculated based on the sensing signal from the motion sensor unit 131 in the left insole 100L and the right insole 100R out of the right inverse 100R.

FIG. 9 (b) illustrates the calculation of the stride D2 by the pressure sensor unit 133 during the second period after the first period. Particularly, except for the third pressure sensor 133c which is not operated among the pressure sensor portion 133 in the left insole 100R and the right insole 100R out of the right inverse velocity 100R, The stride D2 is calculated on the basis of the foot pressure signal from the control valves 133a and 133b.

9B, the processor 170 sets the second period T2 to be longer than the first period T1. During the second period after the first period, the motion sensor unit 131 Can be controlled to be inactivated.

This makes it possible to reduce the activation period of the motion sensor unit 131, which is relatively larger in power consumption among the motion sensor unit 131 and the pressure sensor unit 133. Accordingly, And so on.

10A illustrates the calculation of the first walking angle? 1 by the motion sensor unit 131 during the first period. In particular, the first walking angle? 1 is calculated on the basis of a sensing signal from the motion sensor unit 131 in the right insole 100R and the right insole 100R among the right insole 100R.

Fig. 10 (b) illustrates the calculation of the second walking angle? 2 by the pressure sensor unit 133 during the second period after the first period. In particular, based on the foot pressure signals from the first to third pressure sensors 133a, 133b, 133c operating among the pressure sensor portion 133 in the left insole 100L and the right insole 100R of the right in- The second walking angle? 2 is calculated.

10B, the processor 170 sets the second period T2 to be longer than the first period T1, and during the second period after the first period, the motion sensor unit 131 Can be controlled to be inactivated.

This makes it possible to reduce the activation period of the motion sensor unit 131, which is relatively larger in power consumption among the motion sensor unit 131 and the pressure sensor unit 133. Therefore, So that it can be calculated accurately.

On the other hand, FIG. 11A illustrates a case where a user is walking on a flat land, and FIG. 11B illustrates a case where a user strolls a stairway.

According to Fig. 11A, the processor 170 of the right insole 100R can calculate the stride as Dy.

On the other hand, according to Fig. 11 (b), the processor 170 of the right insole 100R can calculate the stride as Dx.

In practice, a difference in stride may occur when walking on a flat and stairs, and Dx is smaller than Dy. Particularly, on the basis of the pressure sensor unit 133, the difference between Dy and Dx can be larger in the stride calculation.

In order to reduce this difference, the processor 170 controls the motion sensor unit 131 to be temporarily activated when the computed final stride is out of a predetermined range, and the motion sensor unit 131 It is possible to control to calculate the stride again.

As shown in the figure, the processor 170 may control the motion sensor 131 to provide the activation signal Sact or to supply power from the power supply 190.

That is, as shown in Fig. 11 (b), when the difference between the calculated stride Dx and the stride Dy calculated in the flat area is within a predetermined range (the ratio of the difference is approximately 85% or less) It is possible to control the motion sensor unit 131 to be temporarily activated for calculation of the stride length and to control the stride count again based on the sensing signal from the motion sensor unit 131. [

As described above, the calculated stride can be approximated to Dy by the stride calculation by the motion sensor unit 131 during the stair walking. Therefore, it is possible to improve the accuracy of the stride width even when walking the stairs.

As another example, when the user performs an operation to hit the foot on the floor three times in succession, for example, by the action of the specific pattern of the user 70, the pressure sensor unit 133 outputs the corresponding foot pressure signal, Based on this, the processor 170 can control the pairing to be performed based on the specific pattern of foot pressure signal.
