Description

Shoe insole, shoe and gait correction system having same

The present invention relates to a shoe insole, and more particularly to a shoe insole, a shoe and a gait correction system having the same.

A person's walking posture contains a lot of data related to that person's health. Therefore, when the walking data to analyze the walking posture of a person is secured, it is possible to provide a personalized service related to the health. In recent years, efforts have been made to extract gait data by attaching at least one sensor to a shoe insole in order to analyze a person's gait posture. In this regard, when looking at the shape of a person's gait, most people walk in an 11-character gait that walks with two feet in the form of an 11-character walk, an 8-way gait that walks with both feet outward, or two feet walking inward. I'm walking with my eyes. For example, a person's gait shape may be judged as an 11-character gait if the foot-center axis extends below 7.5 degrees in the direction of progression, and if it is spread outward beyond 7.5 degrees, an 8-step gait It may be judged as, and if it is inwardly exceeding 7.5 degrees, it may be judged as the eyeball gait.

In general, it is well known to people that the 11-character walk is a normal walk. In addition, the 8-character gait is accompanied by the so-called truncated gait, which is very short on the heel and long to close the entire foot. (For example, known as the Masai walking method, etc.), it is essential for the spine health or the like that a person's gait form is habituated to an 11 gait. Therefore, most people try to walk with 11 steps, but since the type of walking is habitual behavior, if people do not consciously keep the 11 steps long for a long time, It is very difficult to correct the shape to 11 steps. Therefore, it is required to continuously inform people of the type of their walking so that people walk consciously with the 11-character walking.

1 is a block diagram showing a shoe insole according to embodiments of the present invention, Figure 2 is a view showing an example of pressure sensing sensors distributed in different positions of the flexible body in the shoe insole of FIG.

1 and 2, the shoe insole 100 includes a flexible body 120, first to nth (where n is an integer of 2 or more) pressure sensing sensors 122_1,..., 122_n and a controller. 140 may be included. However, in FIG. 1, the controller 140 is illustrated as being positioned outside the flexible body 120, but according to an embodiment, the controller 140 may be located inside the flexible body 120.

The flexible body 120 may be made of an elastic flexible material, and as shown in FIG. 2, the flexible body 120 may have a shape of a human foot. Thus, the flexible body 120 may be divided into a plurality of regions. In one embodiment, the flexible body 120 includes a heel region (RPR), a plantar region (specifically, may be divided into a lateral region of the sole of the sole (OPR) and a medial region of the sole of the sole (IPR)) and an anterior heel region (FPR). It can be divided into. The first to n th pressure sensing sensors 122_1,..., 122_n are distributed in different positions of the flexible body 120, and when pressure is applied to the flexible body 120 by a wearer, the first to n th pressure sensing sensors 122_1,. The n th sensing data DAT may be output. In one embodiment, the number of first to nth pressure sensing sensors 122_1,..., 122_n is set to a multiple of two, and the first to nth pressure sensing sensors 122_1, ..., 122_n are May be distributed to the left and right of the flexible body 120 to measure the left and right balance. In this case, the first to n-th pressure sensors 122_1,..., 122_n may form two sensing pairs in the flexible body 120. For example, as shown in FIG. 2, the first to eighth pressure sensors 122_1,..., 122_8 may be located on the flexible body 120, and the first to eighth pressure sensors. The fields 122_1,..., 122_8 may be distributed from side to side about the foot-center axis CAX, and the first to eighth pressure sensing sensors 122_1,. One sensing pair can be achieved. That is, the first pressure sensor 122_1 and the fifth pressure sensor 122_5 may form one sensing pair, and the second pressure sensor 122_2 and the sixth pressure sensor 122_6 may sense one sensing pair. Pair, the third pressure sensor 122_3 and the seventh pressure sensor 122_7 may form a sensing pair, and the fourth pressure sensor 122_4 and the eighth pressure sensor 122_8 May form one sensing pair.

On the other hand, as the flexible body 120 is divided into a heel region (RPR), a lateral region (OPR) of the sole, a medial region (IPR) and an heel region (FPR) of the sole, as shown in Figure 2, the first The pressure sensor 122_1 and the fifth pressure sensor 122_5 may constitute the front heel area FPR of the flexible body 120, and the second pressure sensor 122_2 and the third pressure sensor 122_3 may be formed. The outer region OPR of the sole of the flexible body 120 may be configured, and the sixth pressure sensor 122_6 and the seventh pressure sensor 122_7 may include the inner region IPR of the sole of the flexible body 120. ), And the fourth pressure sensor 122_4 and the eighth pressure sensor 122_8 may configure the heel region RRP of the flexible body 120. As such, the first to eighth pressure sensing sensors 122_1,..., 122_8 may not only measure two left and right balances in one sensing pair, but also apply pressure to the flexible body 120. The portion may be divided into a heel region (RPR), a lateral region of the sole (OPR), a medial region of the sole (IPR), and an anterior heel region (FPR). In addition, each of the first to eighth pressure sensing sensors 122_1,..., 122_8 may provide data resolution of two or more levels. In one embodiment, each of the first to eighth pressure sensing sensors 122_1,..., 122_8 is a state in which no pressure is applied (eg, a first stage) and a state in which pressure is applied (eg, Second step) may be sensed. In another embodiment, each of the first to eighth pressure sensing sensors 122_1,..., 122_8 is each free of pressure (eg, first stage), weakly applied (eg , A second step) and a state in which a strong pressure is applied (for example, a third step) may be sensed. However, this is merely an example, and data resolution of two or more levels may be variously implemented. To this end, each of the first to eighth pressure sensing sensors 122_1,..., 122_8 may be implemented as a shoe insole sensor disclosed in the applicant's patent application No. 2011-0125516.

The controller 140 is a flexible body from the first to nth sensing data DAT output from the first to nth pressure sensing sensors 122_1,..., 122_n to determine a walking type of the wearer. The location information and time information (ie, gait information) to which pressure is applied to the 120 may be extracted, and the location information and time information to which pressure is applied to the flexible body 120 may be output. Thereafter, the electronic device (eg, a mobile phone, a smartphone, a smart pad (eg, an Apple iPad or a Samsung company) that receives the positional information and time information to which the pressure is applied to the flexible body 120 from the controller 140. Galaxy Tab, Galaxy Note, Google's Nexus, etc.), a computer, a dedicated mobile device, etc.) may determine the wearer's gait shape based on location information and time information applied to the flexible body 120. Specifically, when the angle between the wearer's foot-center axis (CAX) and the travel direction is calculated based on the positional information and time information applied to the flexible body 120, the wearer's gait shape May be determined based on the angle Θ. At this time, the positional information to which the pressure is applied to the flexible body 120 is k-th (where k is an integer equal to or greater than 1 or less than n) the k-th m + m adjacent to the pressure sensor 122_k and the k-th pressure sensor 122_k. Where m is a positive integer, the distance between the pressure sensors 122_k + m may be represented. In addition, the time information when the pressure is applied to the flexible body 120 is applied to the k-th pressure sensor 122_k and the k-m pressure sensor 122_k + m adjacent to the k-th pressure sensor 122_k. Loss may indicate a time difference. Thus, the distance between the k th pressure sensor 122_k and the k + m th pressure sensor 122_k + m is converted into a diagonal diagonal length, and the k th pressure sensor 122_k and the k + m th pressure detection are converted. When the time difference at which pressure is applied to the sensor 122_k + m is converted into the height length of the triangle, the angle of angle Θ between the wearer's foot-center axis CAX and the direction of travel may be calculated. In general, the distance (ie, length) between the k th pressure sensor 122_k and the k + m th pressure sensor 122_k + m is already determined at the time of manufacturing the shoe insole 100, and the k th pressure sensing The time difference in which pressure is applied to the sensor 122_k and the k + m th pressure sensor 122_k + m is determined by the k th pressure sensor 122_k and the k + j, which are already determined at the time of manufacturing the shoe insole 100. Where j is a positive integer, the length may be calculated based on the distance between the pressure sensing sensors 122_k + j.

Thus, when the height length of the triangle and the diagonal length of the triangle are obtained, the wearer's foot is determined by the formula sin (Θ) = B / A, where B is the height of the triangle and A is the diagonal length of the triangle. The angle between the center axis CAX and the direction of travel Θ can be calculated. At this time, if the site angle Θ between the wearer's foot-center axis (CAX) and the advancing direction is smaller than the preset angle, the gait of the wearer may be determined to be 11-character gait. On the other hand, if the angle between the wearer's foot-center axis (CAX) and the advancing direction (Θ) is greater than the predetermined angle to the outside, the gait of the wearer may be determined to be 8-character gait. In addition, when the site angle Θ between the wearer's foot-center axis (CAX) and the traveling direction is greater than the preset angle inward, the walker's gait may be determined as an eyeball gait. However, this will be described later in detail with reference to FIGS. 3 to 5C. In one embodiment, the preset angle may be set to 7.5 degrees. However, this is merely an example, and the predetermined angle may be variously changed according to a required condition. On the other hand, in order to determine the walking type of the wearer, the controller 140 from the first to n-th sensing data (DAT) output from the first to n-th pressure sensing sensors (122_1, ..., 122_n) Order information on which pressure is applied to the flexible body 120 may be extracted, and order information on which pressure is applied to the flexible body 120 may be output. As described above, the flexible body 120 may be divided into a heel region (RPR), a lateral region (OPR) of the sole, a medial region (IPR), and an heel region (FPR) of the sole. Accordingly, the sequence information in which pressure is applied to the flexible body 120 is a sequence in which pressure is applied to the heel region RRP, the lateral region ORP of the sole, the medial region IPR of the sole, and the front heel region FPR. ) Thereafter, the electronic device that receives the order information on which the pressure is applied to the flexible body 120 from the controller 140 may determine the wearer's gait shape based on the order information on which the pressure is applied to the flexible body 120. Specifically, if the sequence is in order of the heel region (RPR), the lateral region (OPR) of the sole and the front heel region (FPR), the type of gait of the wearer can be determined as a three-time gait. On the other hand, if the sequence is not in the order of the heel region (RPR), the lateral region of the sole (OPR) and the front heel region (FPR), the type of gait of the wearer may be determined to be a gait gait. However, this will be described later in detail with reference to FIGS. 6 and 7.

As such, the shoe insole 100 is a step information (ie, position information, time information and / or sequence of the pressure applied to the flexible body 120) in order to analyze the wearer's gait shape Information) so that the wearer's gait shape can be accurately analyzed. According to an embodiment, the shoe insole 100 further includes an auxiliary sensor having at least one of an acceleration sensor, an angular velocity sensor, or a geomagnetic sensor, so that the gait information (ie, the position where the pressure is applied to the flexible body 120) is provided. Information, time information, and / or order information) may further improve accuracy in analyzing the wearer's gait shape. As a result, the shoe insole 100 can determine whether the wearer's gait is 11-character gait, 8-character gait or eyeball gait in a simple manner, and the wearer's gait is three-times. You can also determine whether you are walking or tortoise walking. In other words, the shoe insole 100 can continuously tell what the shape of their gait if people have to wear only shoes in real life, by allowing people to walk consciously with 11-character gait, human gait form Can be calibrated effectively. In particular, since the shoe insole 100 includes only the flexible body 120, the first to n-th pressure-sensitive sensors 122_1, ..., 122_n and the controller 140, it can be produced at a very low unit cost, It is possible to make gait correction services inexpensive and convenient (ie, universal and popularized). Meanwhile, in the above, when the controller 140 outputs gait information (ie, position information, time information, and / or order information applied to the flexible body 120), the electronic device wears the gait based on the gait information. Although it has been described as determining the gait of the person having ordinary skill in the art will appreciate that the present invention is not limited thereto. For example, the gait of the wearer based on gait information (that is, position information, time information, and / or order information applied to the flexible body 120) in the controller 140 itself in the shoe insole 100. You can also judge by hand.

FIG. 3 is a flowchart illustrating an example in which a wearer's gait form is determined based on gait information output from the shoe insole of FIG. 1, and FIG. 4 is a wearer based on gait information output from the shoe insole of FIG. 1. Figure 5a to 5c is a view showing an example in which the shape of the gait is determined, based on the gait information output from the shoe insole of Figure 1 gait of the wearer 11-character gait, 8-character gait, Or, it is a diagram showing examples that are determined to be eyeball gait.

Referring to FIGS. 3 to 5C, the method for determining a gait shape of FIG. 3 includes a angle between a foot-center axis and a moving direction of a wearer based on positional information and time information applied to the flexible body 120 by a wearer. Θ may be calculated (Step S110), and it may be determined whether the angle Θ between the wearer's foot center axis and the advancing direction is smaller than the preset angle (Step S120). At this time, if the angle between the foot-center axis of the wearer and the advancing direction (Θ) is smaller than the predetermined angle, the gait shape determination method of FIG. 3 determines that the gait shape of the wearer is 11-character gait (Step S130). )can do. On the other hand, if the site angle Θ between the wearer's foot center axis and the direction of travel is greater than the preset angle, whether the site angle Θ between the wearer's foot center axis and the direction of travel is greater than the preset angle to the outside It may be determined (Step S140). At this time, if the site angle Θ between the wearer's foot-center axis and the advancing direction is larger than the preset angle to the outside, the gait shape determination method of FIG. 3 determines the gait shape of the wearer as an eight-character gait ( Step S150). On the other hand, when the angle between the wearer's foot-center axis and the advancing direction is greater than the preset angle inward, the gait shape determination method of FIG. 3 determines the gait shape of the wearer as an inner gait (Step S160). In this case, the preset angle may be set to 7.5 degrees, but the preset angle may be variously changed. Hereinafter, for convenience of description, it is assumed in FIGS. 4 to 5C that the first to eighth pressure sensing sensors 122_1,..., 122_8 are distributedly disposed on the flexible body 120.

FIG. 4 illustrates an example of determining a wearer's gait form (ie, determining whether the gait is an 11-character gait) based on location information and time information to which pressure is applied to the flexible body 120. As described above, the angle Θ between the wearer's foot-center axis CAX and the travel direction PDN may be calculated based on the positional information and time information on which pressure is applied to the flexible body 120. At this time, the positional information to which the pressure is applied to the flexible body 120 corresponds to the distance between the fourth pressure sensor 122_4 and the eighth pressure sensor 122_8, as shown in FIG. 4, the fourth pressure. The distance between the detection sensor 122_4 and the eighth pressure detection sensor 122_8 may be converted into a diagonal length A of a triangle. In addition, since the time information when the pressure is applied to the flexible body 120 corresponds to a time difference when pressure is applied to the fourth pressure sensor 122_4 and the eighth pressure sensor 122_8, the fourth pressure detection sensor 122_4 is provided. The time difference between the pressure applied to the eighth pressure sensor 122_8 may be converted into a height length B of a triangle. As a result, the angle Θ between the wearer's foot-center axis (CAX) and the direction of travel (PDN) is the equation sin (Θ) = B / A, where B is the height of the triangle and A is the triangle Diagonal length). At this time, the distance between the fourth pressure sensor 122_4 and the eighth pressure sensor 122_8 is already determined at the time of manufacturing the shoe insole 100, and the fourth pressure sensor 122_4 and the eighth pressure sensor The time difference at which pressure is applied to the 122_8 may be based on, for example, a distance based on the distance between the fourth pressure sensor 122_4 and the third pressure sensor 122_3 that is already determined at the time of manufacturing the shoe insole 100. It can be calculated as For example, the time when the distance between the fourth pressure sensor 122_4 and the third pressure sensor 122_3 is 105 mm and the pressure is applied to the fourth pressure sensor 122_4 and the third pressure sensor 122_3. When the difference is 21 Hz, if the time difference between the pressure applied to the fourth pressure sensor 122_4 and the eighth pressure sensor 122_8 is 1 Hz, the fourth pressure sensor 122_4 and the eighth pressure sensor 122_8 ) May be 5 mm. However, this is merely an example, and the distance between the fourth pressure sensor 122_4 and the eighth pressure sensor 122_8 may be calculated in various ways. As a result, as shown in FIG. 5A, when the angle between the wearer's foot-center axis CAX and the traveling direction PDN is smaller than the preset angle, the wearer's gait shape is 11 characters. It can be determined as. On the other hand, as shown in FIG. 5B, when the angle between the wearer's foot-center axis (CAX) and the traveling direction (PDN) is greater than the preset angle outward, the wearer's gait shape is 8 characters. It may be determined by walking.
