Description

[0001] SHOE INSOLE, SHOE HAVING THE SAME, AND WALKING FORM CORRECTION SYSTEM [0002]

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

A person's pose includes a lot of data related to the person's health. Accordingly, when walking data capable of analyzing a person's walking posture is obtained, a personalized service related to health can be provided to the person. Recently, efforts have been made to extract gait data by attaching at least one sensor to a shoe insole in order to analyze the walking posture of a person. In this regard, when looking at the shape of a person's gait, most people have an 11-foot walk with two feet in 11-figure form, an 8-foot walk with two feet pointing outward, or a two- I'm walking in a gait. For example, a person's gait pattern can be judged to be an 11-step gait when the foot-center axis is flared up to 7.5 degrees in the direction of travel, and if it fires outward beyond 7.5 degrees, , And if it is widened inward by more than 7.5 degrees, it can be judged to be an ankle walking gait.

In general, it is widely known to people that the 11-foot pedometer is a normal gait pattern. In addition, the 8-legged paddle is accompanied by a so-called toque paddle that has a very short time on the heel and a long closing time, and the 11-padded paddle is a so-called triple paddle that extends to the heel, (For example, known as the "Masai Walking Method"), it is essential for spine health and the like that a person's walking style is changed into an 11-step walking style. Thus, most people are trying to walk on an 11-foot paddle, but because the way people walk is a habitual behavior, if people do not consciously keep the 11-foot paddle for a long period of time, It is very difficult to be corrected with an eleven - step foot shape. Therefore, it is required to continuously inform people about the form of their walking so that they can walk consciously with the 11-step pedometer.

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

1 and 2, the shoe insole 100 includes a flexible body 120, first to n-th (where n is an integer of 2 or more) pressure sensing sensors 122_1 to 122_n, (140). Although the controller 140 is shown as being located outside the flexible body 120 in FIG. 1, the controller 140 may be located inside the flexible body 120 according to an embodiment of the present invention.

The flexible body 120 may be made of a flexible and flexible material. As shown in FIG. 2, the flexible body 120 may have a human foot shape. Accordingly, the flexible body 120 can be divided into a plurality of regions. In one embodiment, the flexible body 120 includes a heel region RPR, a foot region (specifically, an outer region OPR of the sole and an inner region IPR of the sole) and a forefoot region FPR, . The first to nth pressure detection sensors 122_1 to 122_n are dispersed and arranged at different positions of the flexible body 120. When pressure is applied to the flexible body 120 by the wearer, N-th sensing data DAT. In one embodiment, the number of the first to n-th pressure-sensitive sensors 122_1 to 122_n is set to a multiple of 2, and the first to n-th pressure-sensitive sensors 122_1 to 122- Can be distributed to the left and right of the flexible body 120 to measure the left-right balance. In this case, the first to nth pressure sensing sensors 122_1, ..., and 122_n may form one sensing pair in the flexible body 120. For example, as shown in FIG. 2, the first through eighth pressure detection sensors 122_1 through 122_8 may be located on the flexible body 120, The first to eighth pressure detecting sensors 122_1 to 122_8 may be distributed to the left and right around the foot-center axis CAX, and two of the first to eighth pressure- One sensing pair can be achieved. That is, the first pressure sensing sensor 122_1 and the fifth pressure sensing sensor 122_5 can form one sensing pair, and the second pressure sensing sensor 122_2 and the sixth pressure sensing sensor 122_6 can form one sensing pair. The third pressure sensing sensor 122_3 and the seventh pressure sensing sensor 122_7 can form one sensing pair and the fourth pressure sensing sensor 122_4 and the eighth pressure sensing sensor 122_8 can form a pair, Can be a single sensing pair.

Further, each of the first to eighth pressure detection sensors 122_1, ..., and 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 may be in a non-pressurized state (e.g., the first step) and a pressurized state (e.g., The second step). In another embodiment, each of the first to eighth pressure sensors 122_1, ..., 122_8 may be in a non-pressurized state (e.g., the first step), a weakly pressurized state , The second step) and the state in which the strong pressure is applied (for example, the third step). However, this is merely an example, and data resolution of two or more levels can be variously implemented.

Thereafter, the electronic device (for example, a mobile phone, a smart phone, a smart pad (for example, Apple's iPad, Samsung), and the like are input to the flexible body 120 from the controller 140, A Galaxy Tab, a Galaxy Note, a Google's nexus, etc.), a computer, a dedicated mobile device, etc.) can determine the user's walking style based on the position information and time information of the pressure applied to the flexible body 120. Specifically, based on the positional information and the time information of the pressure applied to the flexible body 120, an angle between the foot-center axis CAX of the wearer and the advancing direction

The time information of the pressure applied to the flexible body 120 is obtained by applying pressure to the kth pressure detection sensor 122_k and the (k + m) pressure detection sensor 122_k + m adjacent to the kth pressure detection sensor 122_k Can represent a time difference. Therefore, the distance between the kth pressure sensing sensor 122_k and the k + m pressure sensing sensor 122_k + m is converted into the diagonal length of the triangle, and the kth pressure sensing sensor 122_k and the k + When the time difference of the pressure applied to the sensor 122_k + m is converted into the height length of the triangle, an angle between the foot-center axis CAX of the wearer and the advancing direction

Generally, the distance (i.e., length) between the kth pressure sensor 122_k and the k + m pressure sensor 122_k + m has already been determined at the time of manufacturing the shoe insole 100, The time difference when the pressure is applied to the sensor 122_k and the (k + m) th pressure sensor 122_k + m is determined by the kth pressure sensor 122_k and k + j (Where j is a positive integer) pressure sensor 122_k + j.

)로 설정될 수 있다. 그러나, 이것은 하나의 예시에 불과한 것으로서, 기 실정된 각도는 요구되는 조건에 따라 다양하게 변경될 수 있다. 한편, 착용자의 걸음걸이 형태를 판단하기 위하여, 컨트롤러(140)는 제 1 내지 제 n 압력 감지 센서들(122_1, ..., 122_n)에서 출력되는 제 1 내지 제 n 센싱 데이터들(DAT)로부터 플렉서블 몸체(120)에 압력이 가해진 순서 정보를 추출하고, 플렉서블 몸체(120)에 압력이 가해진 순서 정보를 출력할 수 있다. 상술한 바와 같이, 플렉서블 몸체(120)는 뒷꿈치 영역(RPR), 발바닥의 외측 영역(OPR), 발바닥의 내측 영역(IPR) 및 앞꿈치 영역(FPR)으로 구분될 수 있다. 따라서, 플렉서블 몸체(120)에 압력이 가해진 순서 정보는 뒷꿈치 영역(RPR), 발바닥의 외측 영역(OPR), 발바닥의 내측 영역(IPR) 및 앞꿈치 영역(FPR)에 대하여 압력이 가해지는 시퀀스(sequence)를 나타낼 수 있다. 이후, 컨트롤러(140)로부터 플렉서블 몸체(120)에 압력이 가해진 순서 정보를 입력받은 전자 기기는 플렉서블 몸체(120)에 압력이 가해진 순서 정보에 기초하여 착용자의 걸음걸이 형태를 판단할 수 있다. 구체적으로, 상기 시퀀스가 뒷꿈치 영역(RPR), 발바닥의 외측 영역(OPR) 및 앞꿈치 영역(FPR) 순이면, 착용자의 걸음걸이 형태는 3박자 걸음걸이로 판단될 수 있다. 반면에, 상기 시퀀스가 뒷꿈치 영역(RPR), 발바닥의 외측 영역(OPR) 및 앞꿈치 영역(FPR) 순이 아니면, 착용자의 걸음걸이 형태는 터벅 걸음걸이로 판단될 수 있다. 다만, 이에 대해서는 도 6 및 도 7을 참조하여 자세하게 후술하기로 한다. Thus, if the height of the triangle and the diagonal length of the triangle are found,

) = B / A (where B is the height of the triangle and A is the diagonal length of the triangle), the angle between the foot-center axis CAX of the wearer and the direction of progression

) Can be calculated. At this time, an angle between the foot-center axis (CAX) of the wearer and the advancing direction

) Is smaller than the predetermined angle, the wearer's gait pattern can be judged as an 11-step gait. On the other hand, the angle between the foot-center axis (CAX) of the wearer and the advancing direction

Is greater than a preset angle, the wearer's gait pattern can be judged as an eight-character gait. Also, the angle between the foot-center axis (CAX) of the wearer and the advancing direction

Is greater than a predetermined angle to the inner side, the form of the wearer's gait can be judged to be an ankle gait. However, this will be described later in detail with reference to Figs. 3 to 5C. In one embodiment, the preset angle is 7.5 degrees (

). However, this is only one example, and the actual angle can be variously changed according to the required conditions. On the other hand, in order to determine the form of the user's gait, the controller 140 selects the first to n-th sensing data DAT output from the first to n-th pressure detection sensors 122_1 to 122_n It is possible to extract the order information of the pressure applied to the flexible body 120 and to output the pressure order information to the flexible body 120. [ As described above, the flexible body 120 can be divided into a heel region RPR, an outer region OPR of the sole, an inner region IPR of the sole, and a forefoot region FPR. Therefore, the order information of the pressure applied to the flexible body 120 is a sequence in which pressure is applied to the heel region RPR, the outer region OPR of the sole, the inner region IPR of the sole region, and the forefoot region FPR ). ≪ / RTI > Then, the electronic device receiving the order information of the pressure applied to the flexible body 120 from the controller 140 can determine the type of the user's stepping on the basis of the order information of the pressure applied to the flexible body 120. Specifically, if the sequence is in the order of the heel region RPR, the outside region OPR of the sole, and the forefoot region FPR, the user's walking style can be determined as a three-beat walking pattern. On the other hand, if the sequence is not in the order of the heel region RPR, the outside region OPR of the sole, and the forefoot region FPR, the user's gait pattern can be determined to be a stepping-back gait. However, this will be described later in detail with reference to FIG. 6 and FIG.

Thus, in order to analyze the shape of the wearer's gait, the shoe insole 100 is provided with gait information on the gait pattern of the wearer (i.e., positional information, time information and / or time information on the pressure applied to the flexible body 120) Information) can be outputted so that the form of the user's gait can be accurately analyzed. According to the embodiment, the shoe insole 100 further includes an auxiliary sensor having at least one of an acceleration sensor, an angular velocity sensor, and a geomagnetic sensor, so that the gait information (i.e., the position at which the pressure is applied to the flexible body 120 Information, time information, and / or sequence information), the accuracy of analyzing the user's gait pattern can be further improved. As a result, the shoe insole 100 can judge whether the wearer's gait pattern is an 11-step gait, an 8-step gait or an ankle gait by a simple method, Whether it is a hook or a buckling hook. In other words, the shoe insole 100 can continuously inform the user of the shape of his or her walking style by allowing people to wear shoes only in a real life, and by allowing people to walk consciously with an 11-step shoe, Can be effectively corrected. In particular, since the shoe insole 100 includes only the flexible body 120, the first to nth pressure detection sensors 122_1 to 122_n, and the controller 140, the shoe insole 100 can be manufactured at a very low unit price, Gait correction services can be provided inexpensively and conveniently (i. E., Universalization and popularization is possible).
