Description

Foot Pressure Feedback Control Method of Smart Mat}

The present invention relates to a method of performing feedback control by foot pressure in a smart mat that detects the user's foot pressure to evaluate the user's posture balance and exercise posture.

Because incorrect walking and standing habits can have a negative impact on various body parts such as shoulders, back, spine, and feet, it is very important to maintain body balance and adopt correct walking and standing posture.

However, people with poor walking and standing habits, including the elderly who lack muscle strength in the lower extremities, patients with lower extremity injuries, etc., have unstable walking and standing postures, and may experience discomfort in certain areas such as heels when stepping on the ground or in a standing position. There is a problem with weight being unbalanced.

In such cases, correction of walking posture and standing posture is essential because it not only harms physical health but, in some cases, may lead to high-risk accidents such as falls.

Conventionally, a method of analyzing a subject's walking posture and standing posture was used through various posture analysis devices or posture analysis systems.

However, the majority of such posture analysis devices and posture analysis systems have complex structures and high construction costs, making production and use cumbersome. In addition, the analysis results are only provided as various data, so the user cannot intuitively use them. There was a problem that was not easy to confirm.

To solve this problem, some simpler and more portable posture analysis devices have been designed and distributed, but they all have in common the problem that it is difficult for users to intuitively judge the analysis results of their own posture. there was.

For example, in the past, the evaluator often gave verbal feedback in abstract expressions about the subject moving the center of gravity or exerting force during posture or balance training, and the training was performed using traditional tools, so the effectiveness was improved. There were many cases of falling.

Therefore, a method to solve these problems is required.

In this embodiment, the cases 110 and 120 are formed in detail to have a structure in which the upper case 110 and the lower case 120 are coupled to each other. In particular, the upper case 110 has a light transmitting layer 111 made of a soft material. ) includes.

The substrate 130 is provided in the space between the upper case 110 and the lower case 120 and may include a plurality of pressure sensors 131, a plurality of light sources 132, and a control unit (not shown).

The pressure sensor 131 is arranged in a preset pattern to sense the user's foot pressure applied from the top of the upper case 110.

The pressure sensor 131 may be of any conventional structure and method as long as it can sense pressure applied from the top. For example, a planar Force Sensing Resistor (FSR) may be applied as the pressure sensor 131.

And the light source 132 is arranged in a preset pattern at each position corresponding to the pressure sensor 131 to emit light of multiple colors.

Such light source 132 may be of any conventional structure and method as long as it can irradiate light of different colors according to the size of the sensing value detected by the sensor 131. For example, the light source 132 may be LED (Light Emitting Diode) may be applied.

The control unit is provided to control the light source 132 based on the sensing value of the pressure sensor 131.

Since such a control unit may have any conventional structure and method as long as it can control the operation of the light source 132 based on the signal from the pressure sensor 131, a detailed description of the control unit will be omitted.

In addition to the above components, the smart mat 100 of this embodiment includes a first buffering member 140 provided between the upper case 110 and the substrate 130, and a space between the lower case 120 and the substrate 130. It may further include a second buffering member 150 provided in .

The first buffering member 140 and the second buffering member 150 may be formed of a buffering material capable of absorbing external shock, which prevents the substrate 130 from being damaged by pressure from the top. It is for.

At this time, through holes may be formed in the first buffer member 140 at positions corresponding to the plurality of pressure sensors 131 and the plurality of light sources 132, and thus the light source 132 disposed on the substrate 130 The irradiated light may pass through the through-hole and light-transmitting layer 111 and be transmitted to the outside.

The first buffering member 140 and the second buffering member 150 may be of any type capable of mitigating shock transmitted from the outside, and for example, silicone or rubber may be used.

Figure 3 is a diagram showing the use of the smart mat 100 according to an embodiment of the present invention.

As shown in FIG. 3, a user who wants to evaluate or train his or her posture balance can walk with his or her feet on the top of the smart mat 100, and a pressure sensor located in the area where pressure is applied accordingly ( Pressure is sensed by 131 and the light source 132 is made to emit light in a specific color by the control unit.

Therefore, the user can perform objective posture balance evaluation and training by checking the color of the light emitted from the light source 132.

Meanwhile, as shown in Figure 2, a connector 133 protruding by a predetermined length may be formed on one side of the substrate 130 of the smart mat 100, which is used to electrically connect a plurality of smart mats 100 to each other. It is a composition.

That is, the user can adjust the walking distance by continuously connecting a plurality of smart mats 100 to each other as shown in FIG. 3.

For this purpose, a connection groove may be formed on the other side of the board 130 into which the connector 133 of the other smart mat 100 is inserted inside, and a terminal electrically connectable to the terminal formed on the connector 133 may be formed within the connection groove. can be placed.

In addition, the connector 133 and the connection groove may be formed to be magnetically coupled to each other, but the coupling method of the connector 133 and the connection groove is not limited to this, and various other coupling methods may be applied.

Below, the foot pressure feedback control method of the smart mat 100 as described above will be described in detail. In the following description, the reference numerals shown in FIGS. 1 to 3 will be applied as is.

Figure 4 is a diagram showing the entire process of the foot pressure feedback control method of a smart mat according to an embodiment of the present invention.

As shown in Figure 4, the foot pressure feedback control method of a smart mat according to an embodiment of the present invention includes steps (a) and (b).

First, step (a) is a process in which the pressure sensors 131 disposed in the pressure area where the user's foot pressure is applied generate a sensing value.

That is, when the user steps on the top of the smart mat 100, foot pressure is applied to the area where the user's foot touches, and the pressure sensors 131 placed in the pressure area where foot pressure is applied determine the pressure of the corresponding area. Each sensing value is generated.

And step (b) is a process in which the control unit receives the sensing values of the pressure sensors 131 arranged in the pressing area and controls the emission of at least the light sources 132 arranged in the pressing area.

That is, the control unit receives each sensing value generated from the pressure sensors 131 disposed in the pressurized area, and controls the emission of the light source 132 corresponding to the position of the pressure sensor 131 where the corresponding sensing value was generated. .

At this time, step (b) has the characteristic that the control unit controls the light sources 132 to emit light according to the color assigned to each of a plurality of preset pressure sections with respect to the sensing value of the pressure sensor 131.

That is, the sensing value generated by the pressure sensor 131 can be divided into a plurality of pressure sections according to specific standards, and each pressure section is assigned a different emission color of the light source 132.

In addition, such plural pressure sections are absolutely determined by a relative section setting method that is relatively determined within the range of the maximum and minimum sensing values of the pressure sensors 131 arranged in the pressurized area, or by fixed values set in stages. It can be determined by any one of the absolute section setting methods.

In other words, the relative section setting method is a method of setting the pressure section targeting only the pressure sensors 131 that generated sensing values, and the absolute section setting method is a method of setting the pressure section based on absolute values regardless of whether the sensing value was generated. This is the way to set it up.

In addition, in this embodiment, step (b) controls the light source 132 to emit light based on the feedback mode set at the time the control unit receives the sensing values of the pressure sensors 131 among the plurality of preset feedback modes. can do.

Figure 5 is a diagram showing various types of modes in the foot pressure feedback control method of a smart mat according to an embodiment of the present invention.

As shown in FIG. 5, in this embodiment, the feedback mode may include a uniform expansion control feedback mode and an uneven expansion control feedback mode.

Additionally, in this embodiment, a guide mode operated separately from the feedback mode may be further applied, but this will be described later.

The uniform expansion control feedback mode is a feedback mode that controls the light sources 132 arranged in the pressurized area together with the light sources 132 arranged in the uniformly expanded area expanded outward from the entire circumference of the pressurized area.

In addition, the non-uniform expansion control feedback mode includes light sources 132 disposed in the pressurized area and a light source disposed in the non-uniform expansion area extending outward from the light source 132 corresponding to a specific pressure section within the pressurized area ( 132) is a feedback mode that controls them together.

Below, each of these feedback modes will be described in detail through specific examples.

and in various examples described below. The multiple pressure sections are divided into a total of three pressure sections, and the green-yellow-red luminous colors are set to correspond as the sensing value goes from low to high. Since this is set for convenience of explanation, it goes without saying that the present invention is not limited by each example.

Figure 6 is a diagram showing the detailed process of step (b) performed in the uniform expansion control mode in the foot pressure feedback control method of a smart mat according to an embodiment of the present invention.

7 and 8 are diagrams illustrating the form of light emission of the light source 132 fed back in the uniform expansion control mode in the foot pressure feedback control method of a smart mat according to an embodiment of the present invention.

As shown in FIG. 6, in this embodiment, when the feedback mode is set to the uniform extended control feedback mode, step (b) may include steps (b1-1) to (b1-6) in detail.

Step (b1-1) is a process in which the control unit receives sensing values from the pressure sensors 132 disposed in the pressure region (R1).

Step (b1-2) is a process in which the control unit determines the light emission color by determining which pressure section among a plurality of preset pressure sections corresponds to each of the sensing values of the pressure sensors 132 received in step (b1-1). .

That is, in step (b1-2), the light emission color of the pressure sensors 132 disposed in the pressure region R1 is determined.

Step (b1-3) is a process in which the control unit specifies the pressure sensors 132 located at the boundary of the pressurizing area (R1), and step (b1-4) is a process in which the control unit determines the pressure located at the boundary of the pressurizing area (R1). This is a process of setting an equal extension area (R2) extending outward from the sensors 132.

That is, in the uniform expansion control feedback mode, an equal expansion area (R2) extending outward from the entire circumference of the pressurizing area (R1) is set.

In step (b1-5), the control unit determines the emission color of the pressure sensors 132 arranged in the uniform expansion area (R2) based on the emission color of the pressure sensors 132 located at the boundary of the pressure area (R1). It is a process.

In the case of this embodiment, each of the pressure sensors 132 disposed in the uniform expansion area (R2) emits light from the pressure sensor 132 disposed most adjacent among the pressure sensors 132 located at the boundary of the pressurizing area (R1). It was set to irradiate the same emission color as the color.

However, the emission color of the pressure sensor 132 disposed in the uniform expansion area R2 is not necessarily set as in the present embodiment and may be determined according to various setting standards.

Step (b1-6) is a process in which the control unit controls light emission of the pressure sensors 132 arranged in the pressure area (R1) and the equal expansion area (R2).

That is, in this process, the control unit controls the emission of each pressure sensor 131 to correspond to the emission color determined in steps (b1-2) and (b1-5) described above.

Looking at the examples shown in Figures 7 and 8 according to the above process, Figure 7 shows a case where uniform foot pressure is applied throughout, and Figure 8 shows a case where relatively strong foot pressure is applied to the heel portion.

That is, in Figure 7, when the user steps on the smart mat 100, uniform pressure is applied throughout, and the light source 132 disposed in the pressing area R1 is controlled to emit green overall.

And since all of the light sources 132 located on the boundary of the pressurized area (R1) are controlled to emit green light, the light sources 132 placed in the uniform expansion area (R2) set outside the pressurized area (R1) are also controlled accordingly. All can be controlled to emit green.

In addition, in the case of FIG. 8, when the user steps on the smart mat 100, stronger pressure is applied to the heel portion, so that the light source 132 disposed at the rear of the pressing area (R1) is controlled to emit red, and the light source 132 disposed at the rear of the pressing area (R1) is controlled to emit red. The light source 132 arranged in is controlled to emit green. Additionally, in this example, there is a section where intermediate pressure is applied between the front and back of the pressurized region R1, and the light source 132 in the section is controlled to emit yellow light.

Accordingly, the light sources 132 arranged in the equal expansion area R2 set outside the pressing area R1 are the same as the light source 132 closest among the light sources 132 located at the boundary of the pressing area R1. Emission can be controlled by color.

Next, Figure 9 is a diagram showing the detailed process of step (b) performed in the non-uniform expansion control mode in the foot pressure feedback control method of a smart mat according to an embodiment of the present invention.

10 and 11 are diagrams illustrating the form of light emission of the light source 132 fed back in the non-uniform expansion control mode in the foot pressure feedback control method of a smart mat according to an embodiment of the present invention.

As shown in FIG. 9, in this embodiment, when the feedback mode is set to the non-uniform expansion control feedback mode, step (b) may include steps (b2-1) to (b2-7) in detail. .

Step (b2-1) is a process in which the control unit receives sensing values from the pressure sensors 132 disposed in the pressure region (R1).

Step (b2-2) is a process in which the control unit determines the light emission color by determining which pressure section among a plurality of preset pressure sections corresponds to each of the sensing values of the pressure sensors 132 received in step (b2-1). .

That is, in step (b2-2), the light emission color of the pressure sensors 132 disposed in the pressure region R1 is determined.

Step (b2-3) is a process in which the controller sets the area where the pressure sensors 132 corresponding to a preset specific pressure section among the plurality of pressure sections are distributed as the selection area (R3).

In this step, the control unit selects a pressure section that needs to be visually emphasized among a plurality of pressure sections, and arbitrarily sets the area where the pressure sensors 131 corresponding to the pressure section are distributed as the selection area (R3).

Step (b2-4) is a process in which the control unit specifies the pressure sensors 132 located on the boundary of the selection area (R3), and step (b2-5) is a process in which the control unit determines the pressure located on the boundary of the selection area (R3). This is a process of setting an uneven extended area (R4) extending outward from the sensors 132.

That is, in the non-uniform expansion control feedback mode, a non-uniform expansion area (R4) extending outward from the entire circumference of the selection area (R3) is set.

In step (b2-6), the control unit determines the emission color of the pressure sensors 132 placed in the uneven extended area R4 based on the emission color of the pressure sensors 132 located on the boundary of the selection area R33. It is a decision-making process.

In the case of this embodiment, each of the pressure sensors 132 disposed in the non-uniform expansion area (R4) is one of the pressure sensors 132 disposed most adjacent among the pressure sensors 132 located at the boundary of the selection area (R3). It was set to irradiate the same emission color as the emission color.

In addition, the non-uniform extension area (R4) may be set to have a range that spreads further outward than the above-described uniform extension area (R2) in order to further emphasize its effect.

However, the light emission color and diffusion range of the pressure sensor 132 disposed in the non-uniform expansion region R4 are not necessarily set as in the present embodiment and may be determined according to various setting standards.

Step (b2-7) is a process in which the control unit controls light emission of the pressure sensors 132 disposed in the pressure region (R1) and the uneven expansion region (R4).

That is, in this process, the control unit controls the emission of each pressure sensor 131 to correspond to the emission color determined in steps (b2-2) and (b2-6) described above.

Looking at the examples shown in Figures 10 and 11 according to the above process, Figure 10 shows a case where uniform foot pressure is applied throughout, and Figure 11 shows a case where relatively strong foot pressure is applied to the heel portion.

That is, in Figure 10, when the user steps on the smart mat 100, uniform pressure is applied throughout, and the light source 132 disposed in the pressing area (R1) is controlled to emit green overall.

In this way, when a uniform pressure is applied to the pressurized area (R1) as a whole, the separate selection area (R3) is not temporarily set, and therefore the uneven extended area (R4) is also not set, so the pressurized area (R1) is not set. Only light sources 132 can be controlled to emit light.

In addition, in the case of Figure 11, when the user steps on the smart mat 100, stronger pressure is applied to the heel portion, so that the light source 132 disposed at the rear of the pressing area (R1) is controlled to emit red, and the light source 132 disposed at the rear of the pressing area (R1) is controlled to emit red. The light source 132 placed in is controlled to emit green. Additionally, in this example, there is a section where intermediate pressure is applied between the front and back of the pressurized region R1, and the light source 132 in the section is controlled to emit yellow light.

In this case, the area where the light sources 132 whose emission is controlled to be red and the area where the light sources 132 whose emission is controlled to be yellow are arranged may be set as separate selection areas (R3).

Accordingly, the light sources 132 arranged in the non-uniform extension area R4 set outside the selection area R3 have the same color as the light source 132 that is closest among the light sources 132 located on the boundary of the selection area R3. Light emission can be controlled.

Each feedback mode and its specific examples have been described above, and hereinafter, the process of displaying a guide pattern on the smart mat 100 separately from steps (a) and (b) will be described.

Figure 12 is a diagram showing an additional process for displaying a guide pattern in the foot pressure feedback control method of a smart mat according to an embodiment of the present invention.

13 to 15 are diagrams exemplarily showing the light emission form of the light source 132 for displaying a guide pattern in the foot pressure feedback control method of a smart mat according to an embodiment of the present invention.

As shown in FIG. 12, this embodiment may further include steps (ex1) and (ex2) for displaying a guide pattern.

Step (ex1) is a process in which the user terminal 10 transmits, through control software, a control command to display a guide pattern of a preset shape on the smart mat 100 using the light sources 132 to the control unit.

And step (ex2) is a process in which the controller controls the emission of light sources 132 arranged in the guide area corresponding to the guide pattern in the smart mat 100 according to the control command.

To this end, the control unit may be connected to enable wireless communication with the user terminal 10, and control software programmed to control the control unit may be installed in the user terminal 10.

At this time, the user terminal 10 refers to any type of computing device that can be used by a training subject or examiner, such as a mobile terminal, personal computer, or server.

And the guide pattern refers to a pattern formed by the light source 132 on the smart mat 100 to help trainees who perform balance training, rehabilitation training, sports training, etc., understand the training, which is displayed on the user terminal ( 10) Can be set by the installed control software.

For example, FIGS. 13 and 14 are guide patterns preset in the control software of the user terminal 10, FIG. 13 is a guide pattern for performing C.O.P. training evaluation, and FIG. 14 is a guide for performing rehabilitation training evaluation. It illustrates the pattern.

And FIG. 15 illustrates the control unit controlling the emission of light sources 132 according to a guide pattern arbitrarily input by the owner of the user terminal 10 through the user terminal 10. In this way, the guide pattern may be arbitrarily input through the user terminal 10.

At this time, referring again to FIG. 5, as described above, in this embodiment, a guide mode that operates separately from the feedback mode can be further applied.

Accordingly, when the above-described step (a) is performed while the light sources 132 arranged in the guide area in step (ex2) are emitting light, step (b) is performed by the control unit among a plurality of preset guide modes, The light sources 132 can be controlled to emit light based on the guide mode set at the time of receiving the sensing values of the pressure sensors 131.

And in this embodiment, the guide mode may include a fixed guide mode and a variable guide mode.

The fixed guide mode is a mode in which the emission states of the light sources 132 arranged in the guide area are fixed and the emission control in step (b) is performed only for the remaining light sources 132.

That is, in the fixed guide mode, the light source 132 disposed in the guide area emits light to display a guide pattern regardless of the sensing value of the pressure sensor 131.

In addition, the variable guide mode allows light emission control to be performed in step (b) for the light sources 132 that need to be controlled in step (b) among the light sources arranged in the guide area, and for the remaining light sources 132. This is a mode that fixes only the luminous state of the lights.

That is, in the case of the variable guide mode, among the light sources 132 arranged in the guide area, the light source 132 corresponding to the pressure sensor 131 that generated the sensing value in step (a) stops displaying the guide pattern and (b) )The light emission can be controlled by the control unit in the step.

As described above, in the present invention, the control unit receives the sensing values generated by the pressure sensors 131 disposed in the pressure area where the user's foot pressure is applied and controls the light source ( 132), the balance state of the posture is immediately visually displayed, allowing the user to intuitively recognize this and correct the posture, thereby effectively learning the correct walking posture and exercise posture.

Meanwhile, in another embodiment of the present invention, the smart mat 100 may further include height sensors arranged in a layer on the lower side than the pressure sensor 131 for detecting the user's foot pressure.

The height sensor is provided to map the curvature of the floor surface with which the smart mat 100 is in contact, and a plurality of height sensors may be arranged over the entire area of the smart mat 100.

And each height sensor generates a sensing value containing height information and transmits it to the control unit. Afterwards, the control unit maps the curved shape of the floor using the sensing value of the height sensor to determine the location and height of the unevenness formed on the floor.

The reason for mapping the curvature of the floor surface in this way is that when foot pressure is applied to the upper part of the smart mat 100, errors may occur in the sensing value depending on the curvature of the floor. For example, a sensing value higher than the actual user's foot pressure may be generated at a protrusion on the floor, and a sensing value lower than the actual user's foot pressure may be generated at a depression on the floor.

Therefore, in another embodiment of the present invention, the control unit maps the curvature of the floor using the sensing values sensed through the height sensors, and generates pressure generated by the pressure sensor 131 at a position corresponding to the protrusion and depression of the floor. By correcting the sensing value, the accuracy of the results can be further improved.

For this purpose, the control unit can function and store a compensation value to be compensated for from the sensing value of the pressure sensor 131 according to the sensing value according to the height of the height sensor, and calculate the corresponding compensation value accordingly to calculate the compensation value of the pressure sensor 131. Sensing values can be corrected.

As described above, the preferred embodiments according to the present invention have been examined, and the fact that the present invention can be embodied in other specific forms in addition to the embodiments described above without departing from the spirit or scope thereof is recognized by those skilled in the art. It is self-evident to them. Therefore, the above-described embodiments are to be regarded as illustrative and not restrictive, and thus the present invention is not limited to the above description but may be modified within the scope of the appended claims and their equivalents.
