6 is a flowchart illustrating a posture correcting method according to an embodiment of the present invention.

First, the user wears a cervical spine state monitoring sensor device for monitoring a bent state of the cervical spine and a posture state monitoring sensor device for monitoring a standing posture and a sitting posture (S601), and then drives each sensor device to The basic resistance value for each posture state is measured, and the measured basic resistance value is stored as a database (S603).

The cervical spine monitoring sensor device has a shape as shown in FIG. 3, and is mounted on the back of the user's head as shown in FIG. 8. At this time, it is preferable that the cervical spine monitoring sensor is mounted so as to be located in the center of the back of the neck from the center of the back of the user's head. Thereafter, as shown in FIG. 8, the resistance value for each posture state is measured such as a posture in which the head is normally raised, a posture of bowing the head, and a posture of tilting the head backward.

In addition, the posture state monitoring sensor device is mounted on both sides of the user's shoes, as shown in FIG. In this case, although the posture state monitoring sensor is mounted on the heel portion of the shoe, it may be mounted on the heel portion of the shoe. Then, as shown in Figure 9, standing posture, standing posture obliquely to one side, sitting posture, sitting cross-legged and sitting posture with the hips forward to measure the resistance value for each posture state.

At this time, the resistance value for each posture state measured by the cervical spine state monitoring sensor device and the posture state monitoring sensor device will be described in detail later in the validation and result parts, but will be measured more than once, not only once, but measured. It is preferable to store the average value of the calculated values and a tolerance range in which the ± standard deviation value is applied to the average value as a basic resistance value in the database. This is shown in the table shown in the Validation and Results part.

Then, each sensor device, that is, cervical spine monitoring sensor device and posture condition monitoring sensor device is mounted on the user's corresponding part (back of the head and shoes) to continuously monitor the user's posture to collect the resistance value, the collected resistance value It is transmitted to the portable device possessed by the user in real time, and transmitted to the database and stored (S605).

In this case, each sensor device includes a wireless communication unit for performing a communication connection to a wireless network in order to transmit the collected value to the portable device and the database, and the above description uses Zigbee based on IEEE 802.15 WBAN. However, other short-range communication methods such as Bluetooth may be used.

In addition, the portable device refers to a small terminal device that a user can carry and input while carrying, and is also called a handheld device, and is a mobile phone, a personal digital assistant (PDA), a portable multimedia player (PMP), and a tablet PC. And the like.

The portable device may further include a display window for showing a current state to the user, a speaker for outputting a warning sound, a wireless communication unit for receiving a signal from the sensor device and connecting to the database, and a control unit for controlling such an operation. It may include. At this time, the database is also preferably provided with a wireless communication unit for wireless communication.

The controller of the portable apparatus retrieves the basic resistance value stored in the database and compares the resistance value corresponding to the received posture state of the current user to determine whether the current posture state of the user is a proper posture or an improper posture ( S607), the determined result is shown to the user through the display window (S609).

First, referring to the cervical cervical state determination algorithm of FIG. 7B, the cervical cervical state monitoring sensor corresponding to the resistance value transmitted from the cervical cervical state monitoring sensor device mounted on the user's head has an angle, for example, a cervical cervical cervical angle stored in a database. The basic resistance value corresponding to the state, for example, compares whether the error of the fit angle is within the allowable range (S751), and if it is within the allowable range, it is determined that the cervical spine is a suitable posture (S753). When the cervical vertebral angle is smaller than a predetermined angle by comparing it to a predetermined angle or less (S755), if it is smaller than a predetermined angle, it is determined that the cervical spine is in an inadequate posture due to bowing of the head (S757). If the angle of cervical vertebra is greater than a certain angle more than a suitable angle, the head is tilted backward. It is determined that the combined position (S761).

In addition, referring to the posture state determination algorithm of FIG. 7A, first, the pressure of both feet is compared with 0 or less (S701), and if it is 0 or less, it is determined that both feet are lifted from the bottom and are in an inappropriate position (S703). If it is 0 or more, the difference between the pressure and the pressure of both feet in the sitting position is compared with the allowable range (S705). If it is within the allowable range, it is determined that it is a proper sitting position (S707). When the pressure is 0 or less (S709), if it is 0 or less, it is determined that the left leg is twisted on the right leg and is in an unsuitable position (S711). S713), when it is less than or equal to zero, it is determined that the right leg is in an unsuitable posture with a sitting position twisted over the left leg (S715).

Subsequently, if the pressure of the right foot is 0 or more, the error between the pressure of both feet and the basic pressure of the standing posture is compared with the allowable range (S717), and if it is within the allowable range, it is determined that it is a suitable posture standing correctly (S719). If it is outside the allowable range, the pressure of the left foot is compared to 0 or less (S721), and if it is 0 or less, it is determined to be an unsuitable posture leaning obliquely toward the right leg (S723). Compare the cognition (S725), and if less than 0, it is determined that it is an inappropriate posture leaning obliquely toward the left leg (S727).

The result determined by the posture state and the cervical spine state determination algorithm as described above is displayed on the display window of the portable device which the user carries so that the user can recognize the current posture state and the cervical spine state of the user.

Validation and results

In order to verify the validity of the present invention, data were measured for 3 months using the test body. In order to be applicable to the diversity according to the user, each posture data is measured 100 times at the time of setting before driving, and the estimation range for each posture is set by applying the average and its standard deviation value. Therefore, the same algorithm can be used for light women or heavy men because it is set to a relative value rather than an absolute value.

Cervical spine monitoring device shows the result as shown in Figure 8 when the user wears. The left side shows the angle of the cervical spine according to the posture after the user wears, and the right side receives and stores data from the cervical spine state monitoring sensor device worn by the user, and monitors and shows the current state in real time. When the head is bowed, the cervical spine monitoring sensor is not bent at all, so it is a fixed value and there is almost no deviation. However, in the case of the upright posture or the tilted back position, the value is slightly different for each measurement, so a deviation occurs.

Therefore, sufficient tolerance setting is necessary in order to prevent the malfunction of the sensor apparatus against the fine movement. That is, according to the following [Table 1], the average value of the normal value (upright head) is 472.3, the head is bowed 496.6, the head tilted 425.8, so the allowable range for the fit is the average value ± Standard deviation is applied based on this standard and ± Standard deviation value is applied to each measured value for the allowable range for non-conformance determination. After applying the tolerance range, the recognition rate is 98% in normal, 100% in lean, 96% in lean, and shows the average recognition rate of 98%.

Posture after user wear Number of measurements medium Standard Deviation Recognition rate normal 100 472.3 10.3 98% Bow 100 496.6 0.1 100% Wetting 100 425.8 16.8 96%

<Measurement result of cervical spine monitoring sensor device according to posture>

The posture condition monitoring sensor is mounted on the left and right shoes, and if you sit cross-legged or lean on one foot, the pressure on the sole of the foot in the sitting and standing state is not used. The posture of the user is estimated using the difference.

The pressure sensor under load is installed in two places of the front heel and the heel, but only the data of the heel sensor is used for the posture estimation. If you stand up straight with your chest, most of your weight will be on your heel, and even in a sitting position, your weight will be on your heel. Therefore, there was no problem in monitoring the posture even if the sensor on the front side was removed.

According to [Table 2] below, like the cervical spine monitoring sensor device, the average value was calculated for each posture, and the recognition rate for each posture was measured after giving the value of ± standard deviation as the allowable range. Showed.

Cervical vertebrae for measuring the resistance value of the cervical spine using a cervical state monitoring sensor that has a shape that extends in the longitudinal direction from the center of the back of the user's head to the center of the back of the neck and measures the resistance value of the cervical spine. The condition monitoring sensor device and the posture condition monitoring sensor mounted on both of the user's shoes to measure the resistance value according to the pressure applied to the user's feet to measure the resistance value of the standing and sitting postures A first step of measuring and storing a default value for each cervical spine state and a default value for each posture state corresponding to each posture using a posture state monitoring sensor device;
A second step of measuring the cervical spine state value according to the cervical spine state of the user and the posture state value according to the posture state using the cervical spine state monitoring sensor device and the posture state monitoring sensor device;
A third step of wirelessly transmitting the cervical spine and posture state values to a portable device carried by a user;
The portable device compares the cervical spine state value with the default value for each stored cervical spine state, compares the posture state value with the default value for the stored posture state, and determines the current cervical spine state and posture state of the user, and determines the determination result to the user. Informing Fourth Step
Posture correction method comprising a.
