To this end, the user device 200 provides the user with an interface (UI) for selecting the kind of exercise in step S110, and allows the user to select the exercise to specify the exercise for providing the calibration information.

When the user starts the exercise, the insole device 100 measures the pressure distribution through the sensor module 110 in step S120 and transmits the pressure distribution measured through the communication module 120 to the user device 100 in step S130 send.

Then, in step S140, the user device 100 analyzes the pressure distribution according to the movement specified in advance and determines whether the user's exercise posture is correct. At this time, if the user's motion posture is not correct, the user device 100 outputs calibration information including at least one of voice, image, and text for calibrating the user's posture in step S150.

The method of calibrating the exercise posture of the user device 100 will now be described in more detail. FIG. 5 is a flowchart illustrating a method of calibrating a user's exercise posture according to an embodiment of the present invention. FIGS. 6 to 9 are views illustrating a method of calibrating a user's exercise posture according to an embodiment of the present invention to be.

Referring to FIG. 5, the controller 260 displays an interface (UI) for selecting any one of a plurality of motions through the display unit 230 in step S210. An example of such a screen is shown in Fig. For example, the control unit 260 may display a muscle region to be enforced by the user through the display unit 230 as shown in FIG. 6 (a), so that the user can select the muscle region. Accordingly, the control unit 260 displays a screen for selecting a plurality of motions for strengthening the muscular part selected by the user through the display unit 230 through the display unit 230 through the screen as shown in FIG. 6 (B) do. Then, the user can select a motion that he / she wants to perform during a plurality of motions. For example, the user has selected the thigh as the muscle to be strengthened, and accordingly, the exercise that can be selected is assumed to be a squat, a lunge, or the like. When the user inputs an exercise selection signal, the control unit 260 senses the motion through the input unit 220 in step S220, and specifies the motion in the motion for providing the posture correction in step S230. For example, assume that the user has selected a squat. Then, the control unit 260 provides guidance for the exercise specified in step S240. An example of such a screen is shown in Fig. For example, as shown in Fig. 7, the squat position is a position in which the leg width is set to about shoulder width, and the knee is bent about 90 degrees in the standing posture, and the action is repeated. Such guidance may be provided through at least one of voice, text, and images.

On the other hand, the user who has selected the exercise will start the exercise according to the guidance of the user device 100. Then, the insole device 100 can measure the pressure distribution of the user's sole through the sensor module 110. The communication module 120 transmits the pressure distribution of the sole measured by the sensor module 110 to the user device 100. Then, the control unit 260 receives the pressure distribution of the sole through the communication unit 210 in step S240.

Then, the controller 260 analyzes the pressure distribution of the sole in step S260. The pressure distribution represents the strength of the pressure of the entire soles of the user. That is, the pressure distribution indicates the pressure of a certain portion of the sole and the pressure of the certain portion is weak.

Accordingly, the controller 260 determines whether the exercise posture is correct in step S270. As described above, referring to FIG. 7, the squat position is a position in which the leg width is about shoulder width, and the knee is bent by about 90 degrees in the standing posture, and the action is repeated. At this time, the thing to note is that when you sit down, your knees do not cross your toes. Therefore, the pressure distribution of the sole according to the right posture when sitting at the time of squat is strongly shown on the heel side as shown in Fig. 8 (A). However, if the knee exceeds the toes, the pressure distribution on the soles of the feet will strongly appear in front of the sole as shown in Fig. 8 (B). At this time, the storage unit 240 stores in advance the pressure distribution of the sole appearing in the correct posture according to the exercise, and the controller 260 determines the pressure distribution of the sole received from the insole apparatus 100 And the pressure distribution stored in the storage unit 240 are compared with each other to determine whether or not it is a correct posture.

If it is determined in step S270 that the posture is correct, the control unit 260 returns to step S250 and repeats steps S250 through S270 described above. On the other hand, if it is determined in step S270 that the posture is not correct, the controller 260 proceeds to step S280.

In step S280, the control unit 260 outputs the calibration information. The calibration information includes at least one of voice, image, and text for guiding the user to estimate the exercise posture based on the pressure distribution of the user's sole and calibrate the estimated exercise posture to a correct posture. For example, if the sitting motion of the squat is a right posture, a lot of pressure must be applied to the heel as shown in Fig. 8 (A). However, if the received pressure distribution has a large pressure applied to the front of the sole as shown in FIG. 8B, the control unit 260 can estimate that the center of gravity of the user's upper body is forward. Accordingly, the control unit 260 can output text, image, voice, and the like as shown in FIG. 9 as calibration information so that the user has a correct posture. At this time, the controller 260 displays images and text through the display unit 230, and outputs audio and the like through the audio unit 240.

That is, in other words, the control unit 260 estimates the center of gravity of the user based on the pressure distribution, compares the estimated center of gravity with the center of gravity in the correct posture, and if the center of gravity is not correct, The display unit 230 or the audio unit 240 may output calibration information including at least one of voice, image, and text.

Meanwhile, the posture correcting method according to the above-described embodiment of the present invention may be implemented in a form of a program readable by various computer means and recorded in a computer-readable recording medium. Here, the recording medium may include program commands, data files, data structures, and the like, alone or in combination. Program instructions to be recorded on a recording medium may be those specially designed and constructed for the present invention or may be available to those skilled in the art of computer software. For example, the recording medium may be a magnetic medium such as a hard disk, a floppy disk and a magnetic tape, an optical medium such as a CD-ROM or a DVD, a magneto-optical medium such as a floppy disk magneto-optical media, and hardware devices that are specially configured to store and execute program instructions such as ROM, RAM, flash memory, and the like. Examples of program instructions may include machine language wires such as those produced by a compiler, as well as high-level language wires that may be executed by a computer using an interpreter or the like. Such a hardware device may be configured to operate as one or more software modules to perform the operations of the present invention, and vice versa.

As described above, according to the embodiment of the present invention, the user can exercise in a correct attitude through the calibration information according to the embodiment of the present invention without a coach. The present invention can provide a user experience (UX: user experience) that enables a user to exercise alone.
