The IoT device 130 can be connected to the user terminal 140 using Bluetooth or WiFi.

In the ballet trainee 10, one or more markers 12 are attached to each segmental part of the body.

The marker 12 is an LED marker that emits light itself and expresses a color, and may be attached to the clothes of the ballet trainee 10 or directly attached to the skin without being worn on the clothes.

When the ballet trainee 10 takes a ballet motion, the marker 12 is attached to a point where the ballet motion can be distinguished. The markers 12 may be LEDs of different colors or may be LEDs of the same color.

Ballet bar 110 has a handle 111 in a horizontal direction at the top center, two leg parts 112a and 112b connecting and supporting the handle 111 on both sides of the handle 111, and a floor support supporting the floor. It consists of (113a, 113b). The two leg parts 112a and 112b are connected in the middle of the handle 111 and the floor supports 113a and 113b, respectively.

A plurality of piezoelectric sensor structures 120 are formed on the upper surface 110a of the ballet bar 110 at regular intervals in an area where the trainee 10 holds hands or an area where the feet are placed.

The reason for forming the plurality of piezoelectric sensor structures 120 is that hands or feet can be placed on one or more points.

Valet bar 110 forms an IoT device 130 on one side of the inner side, and a switch 136 partially protrudes.

The piezoelectric sensor structure 120 is formed on the upper surface portion 110a of the bar 110, and includes a piezoelectric sensor 121, a pad portion 122, an electrode portion 123, a connection wire 124, and a shock absorber ( 125).

The above-described ballet operation consists of operations of applying pressure to the piezoelectric sensor 121 by holding the ballet bar 110 with a hand or raising a foot.

The piezoelectric sensor 121 is a sensor device that generates an electrical signal according to vibration.

The piezoelectric sensor 121 may detect up-and-down vibration or left-right vibration generated by holding it with a hand or raising a foot. In this case, the up and down vibration or the left and right vibration detected by the piezoelectric sensor 121 may be detected from pressure applied by a hand or foot.

The piezoelectric sensor 121 may generate an electrical signal from the detected vibration. At this time, the electrical signal may appear as a different waveform according to the size and period of the vibration.

The signal processing unit 131 is composed of a low-pass filter and removes noise by passing the electrical signal of the piezoelectric sensor 121.

The A/D conversion unit 132 converts the electrical signal of the piezoelectric sensor 121 received from the signal processing unit 131 into a sensor value of a digital signal.

The sensing controller 133 filters the sensor values of the digital signals received from the A/D conversion unit 132 and periodically stores them in the storage unit 134 . Here, the sensor value of the digital signal represents a pressure value.

When the sensing controller 133 stores the pressure value of the piezoelectric sensor 121 in the storage unit 134, the pressure value measurement time is matched with the pressure value and stored.

The sensing controller 133 transmits the pressure values stored in the storage unit 134 to the user terminal 140 through the wireless communication module 135 at predetermined intervals.

4 is a diagram schematically showing the internal configuration of a user terminal according to an embodiment of the present invention.

The user terminal 140 is installed in front of the ballet trainee 10 using the cradle 20 erected vertically.

As another embodiment, one or more camera modules are formed and installed in various directions, and the marker 12 of the ballet trainee 10 can be photographed in various directions. Of course, in this case, a technology capable of synthesizing or recognizing image information in various directions may be further added.

The video capture unit 141 stores video information including ballet movements in the video information storage unit 142, and matches and stores the video recording time with the video information.

The terminal control unit 143 receives the pressure value of the piezoelectric sensor 121 from the IoT device 130, stores it in the pressure information storage unit 144, matches the pressure value measurement time with the pressure value, and stores it.

At this time, as another embodiment, when storing the received pressure values, the terminal control unit 143 may calculate an average value of several pressure values and store it in the pressure information storage unit 144 .

The synchronization processing unit 145 compares and analyzes the time taken to capture an image of the image information stored in the image information storage unit 142 and the measurement time of the pressure value stored in the pressure information storage unit 144 .

The synchronization processing unit 145 synchronizes the video information and the measured pressure value when the video recording time and the pressure value measurement time are the same, generates exercise information matching the corresponding image information and the pressure value, and stores it in the ballet motion storage unit 147. Save. When the image capture time and the pressure value measurement time fall within a certain error range, it may be determined that they are the same.

The pressure value of the present invention, for example, when a hand or leg is placed on one point on the upper surface 110a of the ballet bar 110, one pressure value is generated, and when placed on two or more points, two More pressure values may be generated.

As another embodiment, the sensing controller 133 of the IoT device 130 is electrically connected to the switch 136 . The ballet trainee 10 presses the switch 136 when one ballet movement is completed.

When receiving the selection signal of the switch 136, the sensing controller 133 stores the pressure value of the piezoelectric sensor 121 in the storage unit 134 through the signal processing unit 131 and the A/D conversion unit 132. At the same time, an image capture request signal is generated and transmitted to the user terminal 140 through the wireless communication module 135.

The terminal control unit 143 controls the image capturing unit 141 to capture image information including ballet movements and store it in the image information storage unit 142.

Thereafter, the synchronization processing unit 145 generates exercise information by matching the image information stored in the image information storage unit 142 and the pressure value stored in the pressure information storage unit 144, and stores it in the ballet motion storage unit 147. . That is, in another embodiment, since the image information and the pressure value are generated at almost the same time, the time for capturing the image and the time for measuring the pressure value are not measured, and it is not necessary to compare or determine whether the time is the same.

The ballet motion storage unit 147 stores a ballet motion exercise app for using a ballet motion program representing a ballet motion manual, and a reference pressure value required for the ballet motion is set for each image information representing a specific ballet motion.

In the ballet motion storage unit 147, a standard pressure value required for each ballet motion is set, and a standard distance between markers representing each ballet motion and an angle between standards are matched and stored.

The ballet motion extractor 148 processes image information stored in the ballet motion storage unit 147 to extract positions and motions of markers included in the image information, and calculates distances and angles between markers.

The ballet motion extractor 148 compares the calculated distance and inter-standard angle with the standard distance and inter-standard angle of the marker 12 stored in the ballet motion storage unit 147 to find a matching standard distance and inter-standard angle. Here, it can be determined that the calculated distance and the angle between the standard and the standard distance and the angle between the standard of the marker 12 are identical when they fall within a certain error range.

The ballet motion extraction unit 148 extracts ballet motions matching the matching standard distance and the angle between the standard ballet motions from the ballet motion storage unit 147 .

When the ballet motion extraction unit 148 extracts a ballet motion that matches the standard distance and the angle between the standards, the terminal control unit 143 generates a success message indicating success in ballet posture and outputs it to the display unit 149, A voice message indicating success in ballet posture is generated and outputted through the speaker 149a.

When the terminal control unit 143 determines that the ballet motion extraction unit 148 cannot extract a ballet motion matching the standard distance and the angle between the standards, a failure message indicating a ballet posture failure is generated and the display unit 149 It calculates the difference angle value between the standard angle and the calculated angle, converts the difference angle value into a voice message, and outputs it through the speaker 149a. For example, the terminal control unit 143 outputs a voice message indicating that the difference angle (52 degrees) between the standard angle (110 degrees) and the calculated difference angle (60) should be further widened.

When the ballet motion extraction unit 143 extracts a ballet motion that matches the standard distance and the angle between the standards, the terminal control unit 143 compares the measured pressure value with the standard pressure value of the ballet motion storage unit to determine whether they match. do.

When the measured pressure value is within the error range of the preset reference pressure value, the terminal control unit 143 finally determines that the ballet posture is successful.

The terminal control unit 143 generates a "beep" sound to output the speaker 149a when the measured pressure value is out of the error range of the preset reference pressure value and is less than or equal to the reference pressure value, and indicates a pre-stored operation description. A voice message is generated and output through the speaker 149a.

The present invention checks the correct posture of the ballet movement. If you lean too much or less on the ballet bar 110 due to the piezoelectric sensor 121 of the ballet bar 110, a "beep" sound comes out and "Please do this motion" outputs a voice. The aforementioned feedback information includes audio output through the speaker 149a or text output through the display unit 149 .

The terminal control unit 143 may store the ballet posture failure and the ballet motion out of the error range of the pressure value as a separate field in the ballet motion storage unit 147 to display the ballet motion that will not be performed later on the display unit 149.
