BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a posture monitoring apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a posture correcting apparatus, a system and a method, and more particularly, to an apparatus, system and method for posture monitoring capable of simultaneously monitoring a bent posture or a side posture.

The unbalanced posture habits of modern people cause illness and pain. Typical examples are turtle neck syndrome due to the use of smartphones during the commute to and from school, back pain caused by unstable posture in the subway, and shoulder stiffness of an office worker who has to sit on a chair for a long time. Scoliosis, pelvic imbalance, swinging, and foot imbalance. An unbalanced posture may cause not only physical effects such as unbalanced growth and development but also mental influences such as loss of concentration.

Many of the above-mentioned sufferers visited the hospital to find out whether they were caused by posture imbalance through x-ray examination, foot low pressure test, body composition test, gait test, body composition test, Direct or indirect treatment is performed.

However, even after the treatment such as chiropractic, the posture or the gait that has become habit for a long time is not easily fixed, and the same symptom is repeated as a result.

In order to solve the disease caused by the posture, it is necessary to correct the posture for keeping the body health, that is, to sit properly, to stand properly, to walk properly, but it is difficult to self-aware, We need means.

Therefore, many devices for monitoring the posture have been developed. Korean Patent Laid-Open Publication No. 10-2017-0017856 (entitled "A posture correcting device interlocked with a terminal") is equipped with a sensor on a cushion to sense a posture of a user and transmits information about a posture to a user . However, such a configuration has a problem that not only the user's posture can be sensed when the cushion gets out of the cushion, but also the user's posture can not be monitored at all when walking.

Korean Patent Laid-Open Publication No. 10-2017-0000353 (title of the invention: bio-signal measurement device for posture correction) is a device for measuring posture of an examinee through the measurement of a living body signal through an electromyographic sensor and an inertial sensor attached to the subject's sports clothes . However, it is difficult to monitor the attitude information such as the user's gait in real time, the configuration is very complicated, and there is a technical difficulty in accurately sensing the degree of the user's waist bend using the bio-signal.

Korean Patent Laid-Open Publication No. 10-2015-0106774 (entitled "POSITION ANALYSIS APPARATUS AND OPERATING METHOD") relates to an apparatus and method for extracting user's attitude information and analyzing attitude information to provide feedback. However, such a configuration has a problem that it is difficult to analyze the user's daily posture because the imaging unit for acquiring an image for the user must be provided. In addition, since the structure is complicated and difficult to wear, there is nothing unsuitable for real life use.

In order to calibrate the user's posture, it is necessary to continuously monitor the user's posture for 24 hours, and analyze and feedback the user's posture. Therefore, the configuration should be simple, high in portability, and able to effectively measure various postures of the user. The user's posture should be able to measure not only the information about the degree of bending of the back but also the distortion information. However, up to now, a means for measuring various information related to the user's posture by a single device has not been developed.

As shown in FIGS. 1A and 1B, the posture monitoring apparatus 100 according to the present invention can be attached along the vertebra of the user U. FIG. Preferably in the waist region of the user U along the spinal direction. Therefore, the posture monitoring apparatus 100 according to the present invention may include attaching means (not shown) for attaching to the skin of the user U.

The attachment means may comprise an attachment pad having an adhesive force. The attachment pad is preferably made of a material that does not affect the skin even if it is attached to the skin of the user U for a long time. For example, the attachment pad can be detachably attached by repeating 5 to 10 times by using a hydrogel. Preferably, the attachment pad is of a replaceable construction. As another example, the attachment means may be in the form of a band surrounding the waist of the user U. The band-shaped attaching means is made of a material having appropriate elasticity and is provided with a velcro and can be appropriately adjusted according to the waist size of the user U.

The posture monitoring apparatus 100 attached to the waist region of the user U senses information related to the posture of the user U and transmits the sensed information to the smart device 200. The user U transmits the sensed information through the smart device 200 It is possible to correct posture by oneself through the posture related information to be transmitted.

The user U operates to twist the waist in the left-right direction R1 or bend or straighten the waist in the forward and backward directions R2 as shown in Fig. 1B. Human anatomically, the planes of the human body can be divided into coronal planes, midsagittal planes, transverse planes, and oblique planes. The coronal plane refers to a vertical plane that passes vertically through one side of the human body to the opposite side and divides back and forth. More specifically, it refers to a plane dividing the human body back and forth around the ear-ear canal and the acromion, And the horizontal plane is a plane passing horizontally parallel to the ground to divide the human body up and down, and the diagonal plane is a plane dividing the diagonal direction from one shoulder end Surface.

The R1 direction in Fig. 1B means a direction bending to the left and to the right with respect to the sagittal plane, and the R2 direction means a direction to bend or stretch back and forth with respect to the coronal plane. Likewise, the R1 direction is a direction in which the waist is twisted to the left and right, and the R2 direction is a direction to bend or stretch the waist back and forth.

The posture monitoring apparatus 100 according to the present invention monitors the accurate posture of the user U by sensing the degree of bending (bending angle) in the left, right, front, and back directions of the waist of the user U, The current posture is displayed as an image through the display unit 200 or the user U notifies the wrong posture through an alarm or vibration so that the user U can recognize his / her posture and calibrate the posture with the correct posture.

The sensor may be a strain gauge or the like. A strain gauge is a sensor that measures strain or deformation by using the principle that the electrical resistance changes when the object is stretched or shrunk with respect to the original length due to tensile, compression, or twisting. When the user U twists his / her waist in the direction R1 in FIG. 1B, the first sensor 111 detects a change amount of the electrical resistance due to deformation (length deformation) of the sensor, Can be determined.

[ For example, vibration may be generated through the haptic reaction unit 130 so that the user U can recognize that the posture correction is necessary. At this time, the reaction pattern and intensity of the haptic reaction unit 130 may vary depending on the posture of the user U.

Meanwhile, the sensing value or analysis data sensed by the attitude monitoring apparatus 100 is transmitted to the smart device 210, and the user U can continuously monitor his or her posture through the smart device 210. [

The smart device 210 includes a touch screen 230 for displaying the degree of bending of the user U in the front, back, left, and right directions as an image or for displaying the current bending angle or the like with respect to a reference value in numerical values.
