[ The motion sensor 243 may include an acceleration sensor 244 and a gyro sensor 245. It is possible to provide only one of the acceleration sensor 244 and the gyro sensor 245 as necessary.

3 is a sectional view in y-z plane of the smart shoe 110 provided with the smart shoe sensor module 200 according to an embodiment of the present invention.

The sole frame 310 of the smart shoe 110 means a direct / indirect area of the wearer's sole. In other words, in the smart shoe sensor module 200, it may mean a frame of an area provided between the foot and the bottom of the wearer. The sole frame 310 includes an insole 311 to which the soles of the wearer directly touch and an outsole 313 and an insole 311 provided at the bottom of the smart shoe module 200 to directly contact the outside, And a midsole (312) which is provided between the upper and lower parts and the outsole (313) and forms a certain volume.

The insole 311 may be an insole commonly referred to as an insole, but may be integrally formed with the insole 311 and the midsole 312, or may be integrally formed with a separate member or an adhesive.

The smart shoe sensor module 200 may be provided on the sole frame 310. The smart shoe sensor module 200 can signalize or digitize it according to the pressure applied by the wearer's walking or running.

FIG. 4 is a time-wise diagram showing the walking of the smart shoe wearer 400 equipped with the smart shoe sensor module 200 and corresponding responses to the signals generated thereby according to an embodiment of the present invention.

When a signal ('1') to the smart shoe sensor module 200 when the wearer 400 touches the bottom of the smart shoe 110 causes the smart shoe 200 to fall off the floor, An off signal ('0') by the module 200 may occur.

The smart shoe sensor module 200 has a value of '1', that is, an ON signal is generated due to a pressure value exceeding a specific value in the state of (2) to (4) of FIG. 4. In the case of (1) and Quot; 0 ", i.e., an OFF signal may be generated in the smart shoe sensor module 200.

The ON signal generated in the smart shoe sensor module 200 may be generated by a predetermined critical pressure value.

The predetermined critical pressure value may be determined according to the material rigidity, elasticity of the smart shoe sensor module 200, the size of the smart shoe sensor module 200, or the distance between the conductive member and the first circuit part.

For example, when the predetermined critical pressure value is made larger, the pressure threshold at which the ON signal can be generated becomes higher. Therefore, the value '1', that is, the ON signal is generated in the smart shoe module 200 only in the case of 2 or 3 And in the case of (1) and (4) - (7), a value '0', that is, an OFF signal may occur in the smart shoe module 200.

Therefore, it is possible to judge the start and end of one step of the wearer through the result of this, and the cycle of each step can be grasped when the step is repeated.

Referring to FIG. 4, the interpretation of ② as the start of the stepping, and the ending point of ⑦ through ⑦, can be interpreted as the end of one step.

In addition, when the change from (2) to (1) is repeated, it is possible to interpret a plurality of steps by grasping one cycle as one step.

2) and / or the gyro sensor 245 (see FIG. 2) among the motion sensors 243 (see FIG. 2), the speed value of the smart shoe sensor module 200 When analyzing a point of '0', an error may occur due to various variables, that is, noise. However, in the present invention, the noise can be removed through the on / off signal using the pressure sensor in the smart shoe sensor module 200, so that accurate step units can be distinguished.

The smart shoe sensor module 200 can operate according to whether the pressure is applied to the sole frame 310 (see Fig. However, it is not required to necessarily be the bottom direction, and if necessary, it may be operated based on the pressure in the direction deviating at a certain angle with respect to the lower direction. When a plurality of smart shoe sensor modules 200 are provided, Direction. ≪ / RTI >

The direction of this pressure may be based on the wearer's general pace and force action, or may vary based on the wearer's different pace and force action for each individual.

The predetermined critical pressure value may be differently applied depending on physical and habitual factors such as a wearer's height, weight, foot size, sex, and age. However, the on / off state of the smart shoe sensor module 200 may depend on the material, the structure, and the like, so that the smart shoe sensor module 200 having the determined material, structure, etc. may have a predetermined critical pressure value. However, although not shown, the critical pressure value may be arbitrarily changed in consideration of sensing data accuracy, noise, and the like of the wearer.

5 is a flowchart illustrating the operation of the smart shoe sensor module 200 according to an embodiment of the present invention.

The control unit 280 may perform current supply and control of the motion sensor 243 based on the on or off signals of the smart shoe sensor module 200.

If the off-signal is continuously generated for a predetermined time or more in the smart shoe sensor module 200, it can be interpreted that the user does not wear the smart shoe 110 or does not move even if worn. Alternatively, even if the user wears the smart shoe 110, it can be interpreted that he did not move to generate the predetermined threshold pressure or more. For example, this may be the case where the user wears the smart shoe 110 and moves lightly even if the user does not touch the floor or touch the floor.

Accordingly, the control unit 280 may perform a system sleep mode (S501) to minimize the power consumed by the smart shoe sensor module 200 by deactivating the motion sensor 243.

If an on signal is generated in the smart shoe sensor module 200 during the system sleep mode, the user may be interpreted as wearing the smart shoe 110 (S502).

Accordingly, the on-signal of the smart shoe sensor module 200, which occurs during the system sleep mode, can activate the control unit 280 (S503). If the control unit 280 is already activated, this step may be omitted.

The control unit 280 can release the system sleep mode of the smart shoe sensor module 200 and start the system (S504). Here, the driving of the system may mean that various electronic components, circuits, sensors, etc. provided in the smart shoe sensor module 200 are turned on.

The control unit 280 compares the generation time interval of the on and off signals of the smart shoe sensor module 200 with a preset time interval in real time (S505).

When the generation time interval of the on and off signals of the smart shoe sensor module 200 is within a predetermined time interval, that is, when the on value '1' is received within a predetermined time, the system operation of the smart shoe sensor module 200 can be maintained (S506).

On the other hand, when the generation time interval of the on and off signals of the smart shoe sensor module 200 exceeds the predetermined time interval, that is, when the off value '0' continues for a predetermined time or more, The entire system of the system 200 can be inactivated, that is, the system drive can be switched to the system sleep mode. Here, the controller 280 may perform current interruption and deactivation of the motion sensor 243.

6 is a diagram showing the system or circuit configuration of the smart shoe sensor module 200 according to an embodiment of the present invention.

As one of the key components of the smart shoe sensor module 200, the pressure-conducting member 630 according to the present invention can operate in conjunction with the first circuit portion 651. The first circuit portion 651 may be mounted on the substrate 650 so that at least one region may be exposed on the substrate 650.

6 shows a state before the conductive member 630 and the first circuit unit 651 are coupled to each other. The conductive member 630 is separated from the substrate 650 by another member, .

When a pressure less than a threshold value is applied to the smart shoe sensor module 200, the conductive member 630 is electrically separated from the first circuit portion 651.

The first circuit portion 651 can be kept open until the first circuit portion 651 is connected by the pressure conductive member 630, that is, in an electrically open state.

The conductive member 630 may be electrically connected to the contact terminal 6511 of the first circuit unit 651 when a pressure equal to or higher than a threshold value is applied to the smart shoe sensor module 200. [

The two separated contact terminals 6511 may be electrically connected by the conductive member 630 so that the first circuit unit 651 may be a closed circuit. If the first circuit portion 651 constitutes a closed circuit, an electrical signal may be generated.

The control unit 280 (see FIG. 2) can recognize the electric signal generated in the first circuit unit 651 as the on / off signal of FIG. 5 described above, Various operations can be controlled on the basis of this.

Since the controller 280 (see FIG. 2) recognizes the on / off signal according to the electrical signal, it can be interpreted as a separate independent process, but it can also be interpreted as one operation performed in the same one circuit.

6 illustrates two contact terminals 6511 related to the electrical connection and disconnection between the pressure conductive member 630 and the first circuit unit 651. However, the present invention is not limited thereto Do not. For example, at least one of the contact terminals 6511 is sufficient. Also, although not shown, electrical connection and disconnection may be implemented in a non-contact manner instead of the contact method using the contact terminal 6511.

FIG. 7 is a view showing an example of the appearance of the smart shoe sensor module 200 including the circuit configuration of FIG.

FIG. 7A is a front perspective view of the appearance of the smart shoe sensor module 200, and FIG. 7B is a rear perspective view of the appearance of the smart shoe sensor module 200.

The housing 760, which forms the appearance of the smart shoe sensor module 200, may include an upper case 761 and a lower case 762. Alternatively, the upper case 761 and the lower case 762 may be formed as a uni-body, but in the present invention, the upper case 761 and the lower case 762 are formed as separate bodies For example.

Although the smart shoe sensor module 200 is coupled to two cases of the upper case 761 and the lower case 762 for convenience of explanation, the present invention is not limited thereto, and in some cases, three or more The smart shoe sensor module 200 may be formed by combining the cases.

FIG. 8 is a view showing an individual configuration of the smart shoe sensor module 200 according to an embodiment of the present invention.

The smart shoe sensor module 200 may refer to a structural unit for mounting a component that performs the function of the pressure sensor 246 (see FIG. 2), and may physically include the entire configuration mounted within the housing 760 have.

The housing 760 can mount components such as the substrate 650. And an upper case 761 and a lower case 762 provided on the front surface of the housing 760.

The power supply unit 290 may be mounted in the housing 760 to supply power to the controller 280 or the like. And a battery cover 774 coupled to the lower case 762 for smooth replacement of the power supply unit 290. The gap between the battery cover 774 and the lower case 762 is blocked by the waterproof ring 775 so that the waterproofing can be prevented from occurring.

9 is a cross-sectional view taken along the line A-A 'in Fig.

The upper case 761 forms an upper surface of the smart shoe sensor module 200 and can elastically behave by a pressure equal to or higher than a threshold value acting in the first direction. The first direction may in particular mean the direction of the foot from the wearer's foot. In other words, the first direction may mean the direction from the upper case 761 to the lower case 762.

The upper case 761 may be formed in a thin planar shape so that pressure can be easily transmitted from the sole of the wearer to the conductive member 630 and may be provided directly in contact with the conductive member 630. The outer surface of the upper case 761 may be convex so that the pressure from the insole to which the pressure of the wearer's foot or the wearer's foot is transmitted may be transmitted to the upper case 761. The upper case 761 may include a material having elasticity as required to allow the pressure to be sufficiently transmitted to the conductive member 630. For example, the upper case 761 may be formed of a silicon material.

The lower case 762 may be coupled to the lower end of the upper case 761 to form a lower end appearance of the smart shoe sensor module 200.

The first circuit unit 651 may be mounted on the housing 760 formed by the upper case 761 and the lower case 762 and may be fixed to the lower case 762.

A part of the first circuit portion 651 may be exposed from one surface of the substrate 650 and contacted with the conductive member 630 to be described later.

The first circuit portion 651 may be implemented in the form of a combination of a film and a metal electrode, or may be implemented in the form of a film and a conductive polymer. Or in the form of films and CNTs, films and graphene.

Alternatively, the first circuit unit 651 may be provided in the form of an injection mold and an MID (Mold Interconnect Devices).

The substrate 650 can mount the first circuit portion 651. The substrate 650 may also be mounted with a second circuit for driving the motion sensor 243. The substrate 650 may be mounted on the control unit 280 (see Fig. 2). However, it is not necessary to provide the motion sensor 243, the second circuit unit or the control unit 280 in the smart shoe sensor module 200, and the smart shoe 110 may be separately provided as a separate motion sensor A first circuit portion 243, and a second circuit portion or control portion 280 (see FIG. 2).

The conductive member 630 may cause the first circuit portion 651 to generate an electrical signal.

The conductive member 630 may be mounted on the housing 760 formed by the upper case 761 and the lower case 762, And may be provided on the inner side of the upper case 761.

The conductive member 630 is provided on the inner side 7611 of the upper case to form a first gap with the first circuit portion 651. The conductive member 630 is elastically deformed by a pressure exceeding a threshold value acting on the upper case 761 in the first direction, So as to make contact with the first circuit portion 651 and generate a signal.

That is, the conductive member 630 can perform the function of the pressure sensor 246 (see FIG. 2) according to whether the pressure is higher than a threshold value that is applied to the upper case 761 by contacting the first circuit portion 651. An electrical signal may be generated in the first circuit portion 651 when a pressure equal to or higher than a threshold value acts on the smart shoe sensor module 200. [

The conductive member 630 may serve to electrically connect the first circuit unit 651 to the first circuit unit 651. The conductive member 630 may comprise a conductive material. Accordingly, the conductive member 630 may be formed of a conductive silicon, a metal gasket, a metal plate or a metal deposition, a conductive polymer, a CNT, a graphene, or the like.

Alternatively, the first circuit portion 651 may be formed by coupling an injection mold and a mold interconnection device (MID).

For convenience of description, a state in which no pressure is applied to the smart shoe sensor module 200 is referred to as a first state, and a state in which a pressure greater than a threshold value is applied to the smart shoe sensor module 200 is designated as a second state do.

In the first state, the conductive member and the first circuit portion 651 may form the first gap G1. The first gap G1 may be a specific value greater than 0 mm.

The first gap G1 is maintained in the first state and the conductive member 630 and the first circuit portion 651 can be brought into contact with each other by the elastic behavior of the upper case 761 in the second state.

Manufacturing tolerances of the upper case 761 and the lower case 762 at the time of forming the smart shoe sensor module 200 and manufacturing tolerances of the substrate 650 and the conductive member 630 including the first circuit portion 651, The first gap G1 may be varied due to tolerance, tolerance of engagement of the conductive member 630 with the upper case 761, coupling tolerance between the upper case 761 and the lower case 762, and the like.

When the first gap G1 does not have a constant value, the critical pressure value of the signal generation is varied, and a boundary between the on-signal and the off-signal can not be accurately formed.

If an error occurs in an offset between the ON signal and the OFF signal to recognize that a step has occurred but it is recognized that the step has occurred even though the step has not occurred, an error occurs in analyzing the step pattern of the wearer, A problem can arise that results in completely different results.

Therefore, it is necessary to maintain the first gap G1 in the first state, that is, to ensure that the conductive member 230 and the first circuit portion 651 are not in contact with each other to generate the ON signal.

The upper case 761 and the lower case 762 may be coupled to each other by a pair of coupling holes and coupling projections.

The engaging holes and the engaging projections can be fixed in a fitting manner and the case where the upper case 761 and the lower case 762 are unintentionally opened can be prevented.

The coupling hole may be provided on one side of the upper case 761 or the lower case 762, and the coupling protrusion may be provided on the other side.

The engaging holes and the engaging projections can be brought into contact with the respective side faces to exert a fitting effect.

The engaging holes and the engaging projections can form a second gap G2 with respect to the longitudinal direction which is the engaging direction. The second gap G2 may prevent the width of the first gap G1 from varying due to the tolerance generated between the coupling holes and the coupling protrusions.

In a similar manner, the outer boundary of the coupling of the upper case 761 and the lower case 762 may form a third gap G3.

The supporting ribs may protrude downward from the inside of the upper case 761 to support the substrate 650 including the first circuit part 651. [ When the first circuit portion 651 is mounted on the lower case 762, the substrate 650 including the first circuit portion 651 is moved in the flow direction to minimize the tolerance generated in the first gap G1 due to the clearance. It is possible to play a role of not to.

The hook portion may protrude from the inner side of the lower case 762 to fix the substrate 650 including the first circuit portion 651.

The conductive member 730 may be coupled to the inner surface 7611 of the upper case 761. The bonding method may be combined with the adhesive tape or with the formation of the upper case 761 at the same time or at the same time by a double injection method.

The conductive member 730 may be provided in the recessed region of the upper case 761 to improve the reliability of the connection when the conductive member 730 is coupled to the inner side 7611 of the upper case 761. [ have. The recessed region may increase the contact area between the conductive member 630 and the inner surface 7611 of the upper case and may also serve to secure a space such that the thickness of the conductive member 630 is equal to or greater than a predetermined thickness .

10 is a graphical representation of the time of on signal measured by motion sensor 243 of smart shoe 100 and time of on signal measured by pressure sensor 246 in accordance with one embodiment of the present invention. Fig.

The motion sensor 243 can grasp the position of the smart shoe 100 on the three-dimensional space in real time through the acceleration sensor 244 and the gyro sensor 245.

The control unit 280 can confirm whether the smart shoe 200 is in the ON signal state, that is, the '1' value state, or the OFF signal state, that is, the '0' value state, have.

On the other hand, the pressure sensor 246 can analyze the on-signal state estimated to be ground support depending on whether the signal generation threshold pressure value is higher or off signal state estimated to be off the ground.

However, when determining the ON signal or the OFF signal through the pressure sensor 246, an error may occur due to the manufacturing tolerance or coupling tolerance of the smart shoe module 200 described above.

Therefore, the state of the ON signal or the OFF signal measured and analyzed through the pressure sensor 246 needs to be corrected to an ON signal or an OFF signal state measured and analyzed through the motion sensor 243. The opposite is also possible.

11 and 12 are algorithms and flowcharts, respectively, for calibrating smart shoe-on-signal time measurements via pressure sensor 246 to smart shoe-on-signal times via motion sensor 243, in accordance with an embodiment of the present invention .

The smart shoe sensor module 200 may be provided in the left (L) smart shoe and the right (R) smart shoe, respectively, to analyze the wearer's walking pattern and the like.

The smart shoe sensor module 200 provided on the left side (L) smart shoe is referred to as a left side (L) smart shoe sensor module, the smart shoe sensor module 200 provided on the right (R) (L) smart shoe sensor module and the right (R) smart shoe sensor module can be defined as a module, and the unit in which the right (R) smart shoe sensor module is organically measured and analyzed is defined as a smart shoe sensor module system.

That is, the measurement value or the analysis value of either the left (L) smart shoe sensor module or the right (R) smart shoe sensor module can be transmitted to the other smart shoe sensor module, It is also possible to perform the calibration by receiving the measured values and the analyzed values of the sensor module.

In the former case, the left (L) smart shoe sensor module and the right (R) smart shoe sensor module can be regarded as a smart shoe sensor module system. In the latter case, The shoe sensor module and the separate terminal may also be viewed as a smart shoe sensor module system.

The error between the pressure sensor 246 and the motion sensor 243 in Fig. 10 described above can be extended to the problem of the on-signal time of the left smart shoe and the right smart shoe.

The left (L) smart shoe and the right (R) smart shoe may differ in time to support on the ground depending on the wearer's step pattern, that is, the time or pressure ratio of the pressure applied above the threshold value. Therefore, such a deviation may lead to inaccurate results in analyzing the wearer's walking pattern. Therefore, correction of such a balance difference may be necessary.

Right / left side (L / R) smart shoe sensor module 200 due to a complex factor such as a cause of the manufacturing tolerance of each of the left / right (L / R) ) Left / right deviations may occur for analysis of the time that the smart shoe sensor module 200 is supported on the ground.

Therefore, it is necessary to correct the floor support time deviation of the left / right (L / R) smart shoe measured by the pressure sensor 246. [

The correction can be implemented by analyzing the ground support time of the motion sensor 243 provided in each of the left / right (L / R) smart shoe.

The motion sensor 243 can measure the position of the left / right (L / R) smart shoe 110 on the three-dimensional space in real time through the acceleration sensor 244 and the gyro sensor 245 have.

The control unit 280 can analyze the time point and the end point of the actual motion of the smart shoe 110 on the ground.

The left and right smart shoes 110 (left and right) that grasp the ratio of the ground supporting time of each of the left / right (L / R) smart shoes 110 analyzed through the motion sensor 243 as a reference through the pressure sensor 246 ) Can be calibrated (Calibration).

For example, when the smart shoe 110 is used for the first time, the correction algorithm can be automatically activated (S1201).

The control unit 280 controls the three-dimensional movement of the left / right (L / R) smart shoes 110 measured by the motion sensor 243 including the acceleration sensor 244 and the gyro sensor 245, (S1202), and the time ratio of the left / right smart shoe 110 measured by the pressure sensor 246 to the critical pressure value may be analyzed (S1203).

The measurement or analysis step may be simultaneous or contemporaneous.

For example, if the ratio of the ground support time measured and analyzed through the motion sensor 243 is 0.8: 1.2 and the time over which the signal generation critical pressure value measured and analyzed through the pressure sensor 246 is operating is 0.9 : 1.1.

In this case, the control unit 280 multiplies the value measured by the pressure sensor 246 of the left (L) smart shoe in the future by 0.8 / 0.9, and multiplies the value measured by the pressure sensor 246 of the right (R) / 1. 1 may be applied (S1204, S1206).

However, in order to minimize power consumption, the control unit 280 drives the motion sensor 243 only at the initial correction stage of the pressure sensor 246, and may disable the motion of the motion sensor 243 unless necessary .

That is, when performing the correction, the control unit 280 can temporarily activate the motion sensor 243 that is inactivated.

The correction of the control unit 280 may be performed at a cycle set by the wearer, or may be automatically performed at a predetermined cycle (S1205).

1 to 12, the smart shoe system according to the present invention has been mainly described. Hereinafter, a Smart Shoe Tracking Algorithm based on the above-described sensing data of the pressure sensor is described in detail in the PDR algorithm (Pedestrian Dead Reckoning (PDR) algorithm).

In particular, the smart shoe system operated on the basis of the smart shoe tracking algorithm will be described in more detail below.

Here, the smart shoe tracking algorithm can refer to the sensing data of the pressure sensor in the PDR algorithm in order to precisely sense the movement of the smart shoe wearer (e.g., every step or step). Using this smart shoe tracking algorithm, it is possible to more easily and precisely calculate motion data for the footprint of the smart shoe wearer, the walking direction, the stride, and the height. In addition, by using the smart shoe tracking algorithm, the power consumption can be minimized and efficiency can be maximized as compared with the conventional smart shoe system in conjunction with the pressure switch or the pressure sensor circuit or module.

The smart shoe according to the present invention is a smart shoe according to the present invention, as described above, in which a user moves in a state wearing a smart shoe, a velocity, a distance or a position, tracking, recording, etc. of motion data such as trace or path, attitude, stride, and the like. At this time, it is very important to accurately track and sense the footsteps of the smart shoe wearer.

In the present invention, when motion data of a wearer is measured only through motion sensors (also referred to as a PDR sensor or an inertial sensor) such as an acceleration sensor and a gyro sensor in sensing movement data of a smart shoe wearer, Always maintain measurable status. However, activation of such a motion sensor causes continuous battery consumption. In addition, there is a possibility of occurrence of an error, for example, a step is missed when the motion of the wearer can not be precisely distinguished due to the noise generated in the motion sensor at the time of motion data sensing through the motion sensor. An error occurs in the wearer's motion data acquired through the wearer's body and becomes difficult to be relied upon. In order to solve this problem, the present invention further employs the above-described pressure switch or pressure sensor in the above-described motion sensor, and the above description is referred to, and redundant description is omitted here.

Hereinafter, a smart shoe tracking algorithm, motion data sensing through the smart shoe tracking algorithm, and a smart shoe system therefor will be described in detail.

13 is a block diagram illustrating a configuration of a tracking algorithm in a smart shoe system according to an embodiment of the present invention.

Referring to FIG. 13, the smart shoe tracking algorithm may be processed by a configuration called a smart shoe tracking data processing unit 1300 or a tracking data processing unit 1300 (hereinafter, 'tracking data processing unit' for convenience). However, the present invention is not limited to the name of the above-mentioned configuration, but the scope of the rights should be determined by referring to the function or role. The trace data processing unit 1300 may be embodied in hardware such as a circuit or a module or embedded software in a configuration of the smart shoe system described above. 13 to the tracking data processing unit 1300 described herein need not necessarily be a configuration of the smart shoe but may be implemented by other devices such as a mobile terminal capable of receiving and processing sensed data of the sensors of the smart shoe And the like.

The tracking data processing unit 1300 estimates the moving speed (Velocity (3D)) and the moving direction (Attitude (3D)) of the smart shoe wearer through a sensor module mounted on the smart shoe, (Position (3D)) can be cumulatively calculated.

The tracking data processing unit 1300 can process the tracking data for the smart shoe wearer based on the sensing data of the sensor module mounted on the smart shoe using the processing unit 1320 and the filter unit 1350. [ This is related to the PDR algorithm related to the conventional inertial navigation system, and a detailed description thereof is based on the description of the conventional PDR algorithm, and a detailed description of the PDR algorithm is omitted here.

The process of tracking data processing through the processing unit 1320 and the filter unit 1350 will be described first.

The processing unit 1320 includes a first processing unit 1322 and a second processing unit 1324.

The first processing unit 1322 receives the sensed data from the first sensor 1312, processes the received sensed data, and outputs the sensed data to the first integrator. Here, the first sensor 1312 includes, for example, an accelerator sensor. In particular, the first processor 1322 subtracts the gravity from the sensed data from the first sensor 1312.

The second processing unit 1324 receives the sensed data from the second sensor 1314 and processes the received sensed data. The processed data is output to the first processing unit 1322 and the mixer. Here, the second sensor 1314 includes, for example, a gyro sensor. The movement direction data may include yaw data, pitch data, roll data, and the like. The second processor 1324 calculates the moving direction A of the insole of the smart shoe based on the sensed data from the second sensor 1314.

In this case, the output data of the first integrator may be the moving speed data V itself, and the data processed by the second processing unit 1324 may be the moving direction data A of the smart shoe wearer itself have.

In the above, the data excluding the moving speed data v1, i.e., the moving distance data p0 in the output data of the first integrator are inputted again to the second integrator and accumulated. The moving speed data v1, the output data of the second integrator, the moving distance data p1 and the moving direction data a1 of the second processing unit 1324 are input to the filter unit 1350. The filter unit 1350 filters the moving speed data v1, the moving distance data p1, and the moving direction data a1 using, for example, a Kalman filter that is mainly used in the PDR algorithm described above . The input moving speed data v1, the moving distance data p1 and the moving direction data a1 are filtered by the filter unit 1350 to calculate traveling speed data v2, traveling distance data p2, The movement direction data a2 is output. The movement speed data v2, the movement distance data p2 and the movement direction data a2 thus outputted are output to the mixer unit 1360. [

The mixer unit 1360 includes a first mixer for the moving distance, a second mixer for the moving speed, and a third mixer for the moving direction.

The first mixer mixes the movement distance data p1, which is the output of the second integrator, and the movement distance data p2, which is the output of the filter unit 1350, and calculates the final movement distance data P.

The second mixer mixes the moving speed data v1 extracted from the first integrator and the moving speed data v2 output from the filter unit 1350 to calculate the final moving speed data V. [

The third mixer mixes the movement direction data a1 output from the second processing unit 1324 and the movement direction data a2 output from the filter unit 1350 to calculate the final movement direction data A.

If the tracking data processing unit 1300 processes the tracking data for the smart shoe wearer based on the sensing data of the sensor module mounted on the smart shoe using the processing unit 1320 and the filter unit 1350 of FIG. 13, The sensing data as shown in the graph of Fig. 14 can be obtained.

14, based on only the data sensed by the first sensor 1312 and the second sensor 1314, it may not be possible to accurately detect every step of the smart shoe wearer by the noise region 1410. [ This is because it is difficult to precisely measure the zero velocity with respect to each step of the wearer according to the influence of the noise, so that it is ambiguous to distinguish the previous step from the next step, so that a single step can not be detected and missed. For example, a smart shoe wearer may not be a serious problem in a walking or static state, but it may cause an error by affecting the entire data when the moving speed is increased or the stride is narrow. In addition, the noise may occur at every step, which may cause a large error in the entire data. Therefore, an error according to the noise region as described above may affect the reliability of the sensed tracking data, which poses a problem. In this specification, the noise region 1410 does not necessarily mean only a region where noises occur, unlike the name of the noise region 1410. The noise region 1410 may refer to a point or an area where there is a possibility of occurrence of an error in the data sensing process have.

In order to minimize or eliminate errors due to the noise described above, the present invention further refers to the sensing data of the pressure sensor described above.

Referring to FIG. 13, the tracking data processing unit 1300 further includes a detecting unit 1330 and a fourth mixer 1340.

The detection unit 1330 receives the sensed data from the third sensor 1316, processes the received data, and outputs the processed data to the fourth mixer 1340. Here, the third sensor 1316 may be a pressure sensor according to the present invention. Therefore, a detailed description of the pressure sensor will be omitted and omitted from the above description. The data sensed by the pressure sensor can be generated, for example, for each step of the smart shoe wearer. This can be, for example, the graph shown in FIG. 15 or 16.

The detection unit 1330 detects the zero velocity from the data sensed and inputted by the third sensor 1316. This can be easily detected from the graph data as shown in FIG. 14, which is sensed when the third sensor 1316 operates as a pressure switch corresponding to each step of the wearer.

The zero velocity data z1 detected by the detection unit 1330 is mixed with the moving velocity data v1 extracted from the first integrator in the fourth mixer 1340 and the thus mixed data is input to the filter unit 1350 (V1 ') which is different from the input (v1). As described above, the moving distance P, the moving speed V, and the moving direction A data are calculated after filtering in the filter unit 1350. [

Referring to FIGS. 14 and 15, there is a noise region 1410 in FIG. 14 as described above. 15, the data 1510 filtered through the detecting unit 1330 and the fourth mixer 1340 may cancel the noise as shown in FIG. 14 to minimize the zero velocity, To be recognized and processed. Therefore, in the case of Fig. 14 described above, a portion that can be missed for a specific step or the like that may occur is compensated, and accurate data calculation is possible.

Therefore, according to FIG. 16, since the zero velocity is minimized with respect to the motion data of the smart shoe wearer, that is, the movement in the x, y, and z axes, each step can be accurately calculated. Accordingly, It is possible to easily and precisely calculate the detection angle data and the foot angle correction data, so that the movement locus, the moving speed, the moving direction, the stride width, the report, etc. of the wearer can be calculated easily and accurately as shown in FIG. This is because the PDR sensor or the inertial sensor can not accurately acquire the zero velocity of one step, thereby increasing system efficiency and power consumption compared to the case where correction is required due to accumulated errors. In the case of using only the PDR sensor data, the wireless position and positioning correction is required based on Wi-Fi or Bluetooth. However, by using the pressure sensor data, more accurate data sensing is possible without using the wireless positioning method.

In addition, in relation to stride or reporting, conventionally, when a mountain or building stairs are used, the altitude is used as an air pressure sensor. However, in this case, when the ambient pressure suddenly changes due to weather, wind or the like, The pressure change was severe due to other factors such as open and closed, accurate data sensing was impossible, and the reliability of the sensed data was low. On the other hand, in the present invention, zero velocity is minimized based on sensing data of a simple pressure sensor (pressure switch), so that it is possible to easily and accurately calculate data without a pressure sensor or other configuration.

The tracking data processing algorithm according to the present invention is used in a tracking and management service of a wearer's exercise information to measure the calorie consumption amount and weight change of the wearer and automatically recognize bike riding, walking, running and the like, Scheduling services are also possible. In addition, according to the tracking data processing algorithm of the present invention, it is possible to provide a tracking and management service for walking attitude of a wearer (such as a soldier), an indoor navigation service of a mart, a library, a public institution, an outdoor bicycle, Service, tracking and tracking of walking area, exercise measurement and management service using stride and report, and wearer tracking service in GPS or Wi-Fi unavailable area.

17 is a UX diagram of an exemplary service scenario according to an embodiment of the present invention.

FIG. 17A shows a case in which the moving distance of 10 m is walked at an average speed, and FIG. 17B shows UX of the data obtained through the tracking data processing unit in the case of FIG. 17A. Referring to FIG. 17B, the data obtained through the tracking data processing unit with respect to the moving distance of 10 m in FIG. 17A is 10.072 m.

FIG. 17C shows a case in which a moving distance of 10 m is walked at a high speed like an alarm, and FIG. 17D is UX of data obtained through the tracking data processing unit in the case of FIG. 17C. Referring to FIG. 17D, the data obtained through the tracking data processing unit with respect to the moving distance of 10 m in FIG. 17C is 10.066 m.

In addition, FIG. 17E is UX for the stride, speed, and total distance data accumulated through the tracking data processing unit for a predetermined time.

18 is a flowchart illustrating a data processing method using a tracking algorithm in a smart shoe system according to an embodiment of the present invention.

According to the present invention, the tracking data processing unit of the smart shoe system receives sensing data from one or more first sensors (S1802), receives the sensed data based on the operation of the second sensor, (S1804). Here, the first sensors include, for example, the first sensor (acceleration sensor) and the second sensor (gyro sensor) of FIG. 13 described above. Here, the second sensor includes the third sensor (pressure sensor) of Fig. 13 described above.

The tracking data processing unit removes step noise of the sensing data received from the first sensors based on the detected zero velocity data (S1806). The step noise refers to the noise 1410 shown in Fig. 14, and the step noise is removed to indicate that the processing is performed as shown in Fig.

The tracking data processing unit filters the sensing data from which the step noise has been removed (S1808).

The tracking data processing unit obtains the motion data of the smart shoe based on the filtered sensing data and a predefined threshold (S1810). Here, the predefined threshold value may indicate a value according to data normalization according to the filtering in the filter unit. In this way, data normalization can be helpful for data management and so on.

19 and 20 are diagrams for explaining the pairing process between the smart shoe and the mobile terminal according to the present invention.

Based on the above described embodiments, the mobile terminal 1920 can sense motion data in the smart shoe 1910 and thus obtain meaningful data from the sensed data in the smart shoe 1910. [ At this time, in order to facilitate data communication between the smart shoe 1910 and the mobile terminal 1920, a pairing process for data communication must be performed in advance.

For convenience, it is assumed herein that the data communication is based on a Bluetooth communication protocol. Accordingly, the pairing for the data communication is also performed according to the definition of the Bluetooth communication protocol. However, the present invention is not limited to the Bluetooth communication protocol. The communication protocol may be any communication defined for data communication such as Wi-Fi, LTE, Zigbee, Protocol or a communication protocol to be defined in the future.

Meanwhile, the communication protocol is not necessarily used only in the data communication process, but a plurality of communication protocols may be used according to various criteria such as data amount and data attribute. For example, if an emergency data processing such as an emergency alert message (EAS: Emergency Alert Message) or a predefined communication protocol exists for the data processing, it may be followed. In addition, if data communication is not smooth according to the communication environment or the like, another communication protocol can be used.

19A, a first smart shoe sensor module 1912 is mounted on a left (L) smart shoe constituting a smart shoe, and a second smart shoe sensor module 1914 is mounted on a right (R) smart shoe . The first smart shoe sensor module 1912 and the second smart shoe sensor module 1914 may have unique identification data according to a communication protocol for data communication, respectively. For example, referring to FIG. 19A, the first smart shoe sensor module 1912 has unique identification data 'SHV-EKJ2KPS' for data communication. The second smart shoe sensor module 1914 has unique identification data 'PK-A14TS62' for data communication.

This unique identification data may be given at the time of manufacture, for example, according to a predefined communication protocol, for example, Bluetooth, according to a method promised or defined by the communication protocol. This unique identification data may be used for a specific communication protocol, but may be used as it is when another communication protocol is used, and specific identification data may be given for general purpose from the beginning at the time of manufacture. Or it may be arbitrary changeable for the user's identification convenience within a range not hindered by a user or the like in a manner defined by data communication or communication protocol.

The mobile terminal 1920 can provide a connectable Bluetooth communication list 1925 on the screen of the mobile terminal as shown in FIG. 19B when the Bluetooth communication is activated or turned on for data communication with the smart shoe 1910 have.

Thus, the user can select the desired device from the list provided on the mobile terminal 1920, and perform the pairing. However, if a password or the like is set in the selected device, the pairing process can be completed by providing a proper UX and inputting a password. When the pairing is completed, it is difficult for the user to identify whether or not the pairing is properly performed. Therefore, the user may be provided with a smart shoe UX on the screen of the mobile terminal according to the system to show the pairing process, Feedback can be given to easily recognize the result of the pairing.

In contrast to FIG. 19, in FIG. 20, instead of providing a separate list as shown in FIG. 19B, automatic pairing may be performed based on a result of a smart shoe wearer's action. This can help to perform pairing more intuitively and conveniently in various situations such as, for example, a user can not input a mobile terminal, inconvenience, inconvenience, or difficulty of selection when too many device lists are provided on the list.

As shown in FIG. 20A, when the mobile terminal 1920 presses or selects to wear smart shoes according to a guide on, for example, UX, or to connect, the mobile terminal 1920 requires an additional operation for pairing as shown in FIGS. 20B and 20C. In FIG. 20A, if a smart shoe and a pairing request are selected in the mobile terminal, a request is made in FIG. 20B to roll the left foot three times in order to check whether the sensor and the application are operating well. When the smart shoe wearer performs an operation according to the request of the mobile terminal, the left (L) smart shoe sensor module and the mobile terminal are automatically registered and paired. Then, as shown in FIG. 20B, when the requested operation is also performed on the right (R) smart shoe sensor module in FIG. 20C, the mobile terminal automatically performs registration and pairing. FIGS. 20b and 20c are for registering and pairing both smart shoe sensor modules, and their leading ends are arbitrary and not important. On the other hand, if the sensor module is mounted on only one side of the smart shoe, it is sufficient to perform either one of Figs. 20B and 20C.

For example, FIG. 20 performs not only automatic registration and pairing of sensor modules mounted on a smart shoe in a mobile terminal, but also a function of confirming whether data communication is performed smoothly. In addition, when the user does not perform the operations as shown in FIG. 20, it is difficult to determine whether the data sensing is properly performed. Therefore, a correcting operation for more accurate data sensing can be performed through this process. 20B or 20C, the user can intuitively recognize the strength or degree of the pressure for recognizing the step, and it is possible to determine the malfunction of the sensor module or the error itself by itself. Accordingly, the user may correct the sensing sensitivity and the like of the sensor module in some cases. In other words, the sensor module of the smart shoe can have a preset sensing sensitivity and threshold pressure criterion based mostly on average data.

However, even if such a criterion is used, the degree of data sensing that the user feels may be different, so that it can be easily corrected through a process as shown in FIGS. 20B and 20C. For example, assume that the user has performed the process as shown in FIG. 20B or 20C for pairing, as described above. If the user feels sensed differently than the smart shoe wearer in the process, he or she may request a critical pressure correction and provide it in a form similar to UX provided in FIG. 20b or 20c to adjust the critical pressure or the like, as desired by the user. In this case, the threshold pressure adjusted or corrected by Figs. 20B and 20C is transmitted to the smart shoe in the mobile terminal, and the control unit of the smart shoe controls the sensor module appropriately based on the threshold pressure, Classification or transformation processing.

Meanwhile, in FIG. 20, the pairing is performed through the same operation as the step of rolling the foot to the smart shoe wearer, but the present invention is not limited to the number of times of foot-rolling or the foot roll, . Meanwhile, in addition to the steps described above, a list for performing various operations, that is, pairing and the like may be provided and the pairing process may be performed according to an operation selected by the user. In this case, such an operation selected by the user may be used for later application execution or identification of the user. Alternatively, the mobile terminal may automatically pair with a smart shoe when a signal is continuously received by the smart shoe rather than a predetermined pattern after a request for pairing with the smart shoe is received. On the other hand, the mobile terminal may automatically pair a device with the highest signal strength, that is, smart shoes, at the time of a pairing request.

In the meantime, with respect to the present invention, the mobile terminal can distinguish the left (L) smart shoe from the right (R) smart shoe through a predetermined gesture input when the sensor of the smart shoe, in particular, In case of sensor (3 axis of acceleration sensor, 3 axis of gyro sensor, 3 axis of geomagnetic sensor), data received from each sensor module is automatically compared without having to distinguish between left (L) smart shoe and right (R) smart shoe .

In addition, in some cases, such as registering a smart shoe application as a basic application on a mobile terminal, the mobile terminal may lock, unlock, perform a specific function, Execution of an application, control of an executed application, and the like.

In addition, request, selection, function execution, etc. related to smart shoe on the mobile terminal may be performed in various ways such as voice, gesture, eye-tracking, etc., as well as the touch of the mobile terminal, have.

However, Fig. 20 may be performed together with Fig. For example, through FIG. 19, actual data communication start or end after pairing may be performed through FIG. 20, or vice versa.

19 and 20, when the mobile terminal 1920 performs pairing through the smart shoe application for the first pairing with the first smart shoe 1910, the mobile terminal 1920 automatically Pairing may also be performed. However, when the mobile terminal 1920 uses the smart shoe application, a list based on the unique identification data of the smart shoe sensor modules as shown in Fig. 19B is provided at the time of the first pairing, Bluetooth unique identification data of a mobile terminal or the like may be filtered from the list to provide selection convenience. In addition, the above-mentioned automatic pairing can acquire sensed data by taking into consideration user's usage patterns, setting various motion data by using a tracking algorithm, and obtaining smart shoe data, etc., , And related UX provisioning.

21 and 22 are sequence diagrams illustrating a process of automatically pairing smart shoes with a plurality of mobile terminals according to an embodiment of the present invention.

For example, FIG. 21 shows a pairing process through a gesture between a mobile terminal and a smart shoe equipped with a three-axis sensor, FIG. 22 shows a pairing through a gesture between a mobile terminal and a smart shoe equipped with a 9- FIG.

First, referring to FIG. 21, the process of pairing through the gesture between the mobile terminal 2110 and the first smart shoe 2120 and the second smart shoe 2130 will be described in more detail. The first smart shoe 2120 may be a left smart shoe including a three-axis based smart shoe sensor module and the second smart shoe 2130 may be a three-axis smart shoe sensor You can indicate the right (R) smart shoe with the module.

The mobile terminal 2110 first transmits a pairing start request signal to the first smart shoe 2120 (S2102). At this time, the first smart shoe 2120 transmits a pairing start request signal of the mobile terminal 2110 to the sensor unit for activation. The first smart shoe 2120 returns a pairing start response signal in response to the pairing start request signal of the mobile terminal 2110 (S2104). Typically, a response to agree to the pairing start request is included in the pairing start response signal of the first smart shoe 2120 to be returned.

Next, the mobile terminal 2120 transmits a pairing start request signal to the second smart shoe 2130 (S2106). At this time, the second smart shoe 2130 transmits a pairing start request signal of the mobile terminal 2110 to the sensor unit for activation. The second smart shoe 2130 returns a pairing start response signal in response to the pairing start request signal of the mobile terminal 2110 (S2108).

The steps S2102 to S2104 or S2106 to S2108 are performed when the smart shoe sensor module is mounted on the shoe. Accordingly, if both the smart shoes are equipped with the sensor module, steps S2102 to S2108 may be performed. However, if only one smart shoe is equipped with the sensor module, steps S2102 to S2104, S2106, Only a predetermined step may be performed in step S2108. The order of steps S2102 to S2104 or S2106 to S2108 may be different from that shown in the figure.

The steps S2102 through S2108 may be regarded as an initial stage of pairing, for example, a connection step for pairing.

After the initial stage of pairing, the mobile terminal 2110 provides UX as shown in FIG. 19 or 20, and attempts to pair with the smart shoe.

Specifically, the mobile terminal 2110 first performs the authentication procedure with the first smart shoe 2120. 20, the smart shoe wearer scrolls the smart shoe corresponding to the first smart shoe a predetermined number of times. At this time, the mobile terminal 2110 counts the number of times the first smart shoe 2120 is rolled (S2110), and when the predetermined number of counts is reached, the smart shoe is authenticated. At this time, the process may be repeatedly performed in a loop form until authentication succeeds.

If, for example, the authentication fails more than a predetermined number of times or the authentication is not successful within a predetermined time, the authentication process itself is repeatedly reset and the process returns to the pairing initialization step or is executed for the pairing on the mobile terminal 2110 The execution of the application may be terminated.

The authentication process for the first smart shoe 2120 of the mobile terminal 2110 is performed in the same manner for the second smart shoe 2130 (S2112).

When the pairing authentication process for both smart shoes is completed through the steps S2110 and S2112, the mobile terminal 2110 transmits a pairing stop request signal to each of the smart shoes 2120 and 2130 (S2114 and S2118) A response signal to the pairing stop request signal is received from the smart shoes 2120 and 2130 (S2116 and S2120).

Through the above process, the pairing process is completed and data communication is performed between the mobile terminal 2110 and the smart shoes 2120 and 2130.

Meanwhile, the process shown in FIG. 21 is not necessarily limited to the order shown. For example, steps S2106 to S2108 may be performed after step S2110 or step S2114.

Next, referring to FIG. 22, the process of pairing through the gesture between the mobile terminal 2110 and the first smart shoe 2120 and the second smart shoe 2130 will be described in more detail. For example, the first smart shoe 2120 may be a left (L) smart shoe including a 9-axis based smart shoe sensor module, and the second smart shoe 2130 may be, for example, a 9- You can indicate the right (R) smart shoe with the module.

22, the initial stages of pairing between the mobile terminal 2110 and the smart shoes 2120 and 2130 are the same, and the description of FIG. 21 is used and is not repeated. However, in FIG. 21, there are more sensors activated on the basis of the 9-axis sensor in the early stage of pairing than the sensor activated on the basis of the 3-axis sensor in the early stage of pairing.

Meanwhile, in FIG. 22, the pairing authentication process after the initial stage of the pairing, that is, the authentication process is different from that of FIG. For example, in FIG. 21, the mobile terminal 2110 provides the authentication UX and accordingly receives the gesture input of the smart shoe. In FIG. 22, a different method is used. In other words, the mobile terminal 2110 first detects at least one of the first smart shoe 2120 or the second smart shoe 2130 (S2210).

The mobile terminal 2110 authenticates the retrieved smart shoes. At this time, it is assumed that both the first smart shoe 2120 and the second smart shoe 2130 are searched. The mobile terminal first calculates the traces of the first smart shoe 2120 and calculates the same trace for the second smart shoe 2130 S2214. Then, the mobile terminal 2110 compares the calculated traces for the first smart shoe 2120 and the second smart shoe 2130 searched (S2216). In this case, the mobile terminal 2110 transmits a trace calculation value of each smart shoe previously stored in the mobile terminal 2110 (or a server or the like) for authentication, a trace of each smart shoe calculated through the steps S2212 and S2214, Calculated values can be compared. However, the present invention is not limited to this, and various objects capable of recognizing or authenticating each smart shoe may be used in connection with the comparison.

As a result of the comparison in step S2216, if the mobile terminal 2110 fails to authenticate at least one of the smart shoes, the mobile terminal 2110 can re-execute the authentication process for the smart shoes or all the smart shoes. In other words, the authentication process can be repeatedly performed in a loop structure. On the other hand, such repetition may be performed only for a predetermined number of times, and the entire pairing process may be reset and re-performed with respect to the smart shoes or the entire smart shoes which finally fail authentication.

If it is determined in step S2216 that the smart shoe has been authenticated, the mobile terminal 2110 proceeds to the next step. 22, the mobile terminal 2110 transmits a 'LEFT' request allocation signal to the first smart shoe 2120 (S2218), and the first smart shoe 2120 transmits 'LEFT and Stop' (S2220). The request-response process for the first smart shoe is performed in the same manner for the second smart shoe (S2222, S2224).

Through the above process, the pairing process between the mobile terminal 2110 and the smart shoes 2120 and 2130 equipped with the 9-axis sensor can be completed, and data communication can be performed after the pairing is completed.

The pairing process between the smart shoe equipped with the three-axis sensor and the smart shoe equipped with the nine-axis sensor and the mobile terminal shown in Figs. 21 and 22 is an example only, and is not necessarily limited to the illustrated sequence. Also, the pairing angle sequence shown in FIGS. 21 and 22 may not necessarily be a sequence, and at least one sequence may be omitted or skipped, or conversely, at least one sequence may be added depending on the system or situation.

21, the processes for the first smart shoe 2120 and the second smart shoe 2130 can be reversed. For example, in FIG. 21, the first smart shoe 2120 may access the mobile terminal first, as opposed to the second smart shoe 2130, or vice versa. This is also true of FIG.

Although the present invention assumes that the sensor modules are mounted on both smart shoes, even if both smart shoes are shown as shown in FIGS. 21 and 22, It is not necessary to perform the operation. For example, when the pairing process is completed for either one of the smart shoes, the remaining shoes may be automatically paired to a set or a pair automatically without authentication or the like. This is sufficient if the error or problem in the data communication process in the future is newly authenticated or re-authenticated.

23 is a diagram illustrating a service scenario according to an embodiment of the present invention.

FIG. 23A shows a smart shoe, and FIG. 23B shows a smart glove. Hereinafter, a brief service scenario will be described after pairing with such a smart shoe and a smart glove.

Referring to FIG. 23, if a smart application is executed in a mobile terminal after pairing, it can be automatically connected to a predefined data sink time and can be subjected to a sink process. Therefore, the user can conveniently connect the sensors of smart shoes or gloves without performing the pairing process.

Referring to FIG. 23A, in the present invention, the smart shoe sensor module is mounted on each smart shoe, respectively, so that the movement of the left foot and the right foot can be accurately analyzed. Therefore, it is possible to provide services such as posture and injury prevention by analyzing the body data of each position. For example, when a smart shoe wearer rolls a pair of shoes and analyzes the time of ground contact and strength of each foot, it can be used not only for the amount of exercise but also for diagnosing a specific foot load, need for reinforcement, etc. Also, .

Referring to FIG. 23B, unlike FIG. 23A, a smart glove is worn by a user. First, both hands are divided, such as intersecting two hands. Then, swing speed of each arm and impact strength for a specific object are analyzed Coaching services are also available to prevent injuries and improve performance. In addition, the load on both hands can be calculated separately. For example, it is possible to provide a variety of data analysis and coaching services by using such smart gloves in a sports game in which hands are mainly used.

Meanwhile, although not shown, when the smart shoes and the smart gloves are worn at the same time, the automatic pairing and the sinking process can be performed with reference to the contents of the present invention described above, and the comprehensive physical condition and rhythm can be grasped and serviced.

As described above, according to various embodiments of the present invention, each or a combination thereof, it is possible to perform data communication between a plurality of devices and a preparatory process therefor easily and quickly, and to extend terminal functions such as smart shoes, mobile terminals, Not only can it be improved, but it also has an effect of improving the product satisfaction by improving convenience of use.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

The foregoing detailed description should not be construed in any way as limiting and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
