In one aspect of the present invention, the motion sensor 10 is provided in the motion measurement unit 70. The motion sensor 10 is a sensor capable of sensing the movement of a user, and more particularly, a sensor for measuring a hand tremor of a user. That is, the motion sensor 10 is used to detect the shaking of the hand so that an action trammer can be detected during movement of the user. Specifically, the motion sensor 10 may be provided using a sensor using a light emitting element, an infrared sensor, or the like. A sensor using a light emitting element (LED) is a sensor that detects the reflection of light generated by a light emitting element and senses the motion of the hand. The sensor measures the hand tremor by calculating the time and angle . Using a sensor using such a light emitting element, it is possible to measure not only the right and left hand tremors but also the front and back tremors, thereby obtaining more accurate data. An infrared sensor is a sensor that detects infrared information that a person has. The infrared sensor detects the infrared information of the human hand and makes it possible to measure the hand tremor. More specifically, the infrared ray sensor may include an infrared ray projector, and may be provided so as to measure infrared rays reflected by the pixel in units of pixels and to reflect the rays emitted from the infrared ray projector. In order to detect such infrared rays, the camera 20 to be described later may be provided with an infrared camera, but the present invention is not limited thereto. The motion sensor 10 may be provided to use a sensor using a light emitting element and an infrared sensor at the same time.

[ The motion measurement unit 70 may be provided as a separate terminal, but may include an output unit 30 to be described later. Specifically, the motion measuring unit 70 may provide circular and polygonal guiding lines 40 that lead to movement of the user's hand 45. The guideline 40 may be formed with a green circle, as described in Figures 2 and 3, with reference to which the user's hand tremor can be measured. Based on these circles, it detects the hand tremor and makes it possible to measure the user's action tremor. For example, as shown in FIGS. 2 and 3, the movement of the hand 45 is indicated by a red circle to measure how the red circle moves relative to the green circle (guide line) And may be provided to diagnose the action trammers based on the values obtained. More specifically, the distance from the center of the green guide line 40 to the center of the red hand 45 is measured to measure the degree of deviation of the hand 45 through the difference from the green circular radius 43 It is possible to measure the frequency and amplitude of hand tremor and to provide a donut shape with a constant width 47 at the green circular radius 43 so that the center of the red hand 45 (In this case, the frequency of the hand tremor can be measured by measuring the frequency of deviation from the inside of the width 47 and the outside of the width 47 based on the radius 43) . Referring to FIG. 4, numerical values of test results of 15 normal persons in the early 20s are shown. The numerical values of 30 to 30 in FIG. 4 are average values of normal persons, ), And the present invention is not limited thereto. In addition, the distance from the motion sensor 10 and the camera 20 to the hand can be grasped, and the distance of the hand trembling can be measured and data can be obtained. It is a principle that the polygonal guide line 40 measures the distance from the center with the same principle as that of the circular guide line 40. The polygon guide line may be a polygonal shape such as a triangle, a rectangle, a pentagon, or the like, but may be provided in a polygonal shape such as a cloud shape, a thread shape, a star shape, or a combination of a plurality of polygons.

On the other hand, the guide lines 40 provided on the right hand and the left hand can draw the guide lines 40 having different shapes, so that the hand shake measurement data value can be outputted more effectively. That is, by providing different guideline 40 in order to more precisely diagnose the user, it is possible to measure the cognitive ability and the corresponding behavior of the user, thereby more effectively measuring the action tramer patient.

The output unit 30 to be described later displays such a guideline 40 to allow the user to move the hand 45 along the guideline 40. The motion measuring unit 70 may be provided as a key.

It is possible to perform overall control of the hand tremor measuring apparatus 100 by providing the control unit 60 for controlling the hand tremor measuring apparatus 100. [ In addition, the hand tremor measuring apparatus 100 may include a separate power supply unit to supply power to the hand tremor measuring apparatus 100.

The output unit 30 is connected to the motion measurement unit 70 and outputs an image. The output unit 30 may be provided as a separate display device. However, the output unit 30 may be provided as an interface provided in the hand shake measurement apparatus 100 and may be connected to an external display to output an image generated by the hand shake measurement apparatus 100 to an external display The output terminal can be provided. There is an advantage that the configuration of the hand tremor measuring apparatus 100 is simplified when the output unit 30 is provided as an interface. Specifically, the output unit 30 can display the guideline 40. The guideline 40 provides a criterion by which the user can move the hand 45. Allowing the user to move his / her hands along the guideline 40 to measure the hand tremor so that the action trammer can be measured. That is, the user can measure the hand tremor by moving the hand 45 along the guideline 40 displayed on the output unit 30, and the user can check the guideline 40, I make it.

In another aspect of the invention, the measurement of hand tremor utilizes one or more pieces of information selected from the group consisting of frequency and amplitude of hand tremor. In other words, if the frequency and amplitude of hand tremor are similar to those of the action treadmill for the diagnosis of action treadmill, they can identify the action treadmill and notify the user of the action treadmill. There is an effect to make.

In another aspect of the present invention, the communication unit 50 is provided in the hand tremor measuring apparatus 100. [ The communication unit 50 transmits information on hand trembling to the external terminal. The external terminal may be a computer, a notebook, a mobile terminal, a mobile phone, an MP3 player, a PDA, a TV, a smart phone, a smart device, or the like. This makes it possible to more systematically manage the information on the user's hand tremor so that the user can more easily recognize the user's condition.

In another embodiment of the present invention, the hand tremor measurement is measured three or more times. This is to produce more accurate hand tremor measurements. That is, since it is difficult to obtain accurate data in one measurement, it is possible to diagnose an action treadmill patient by using more accurate hand tremor data by measuring hand tremor more than three times. More than three times the hand tremor is measured to make it possible to extract more reliable data.

In a preferred embodiment of the present invention, referring to FIG. 4, (a) is a hand tremor measurement value of a normal person, and (b) is a hand tremor measurement value of an action tremor patient. The upper green line and the lower green line represent the range of the guideline (40), and the numerals entering the upper green line and the lower green line are normally shifted. If they are out of the green line, they are out of range. In other words, it can be concluded that the amplitude of the hand tremble is large when it deviates from the green line. In addition, the horizontal value in FIG. 4 indicates the frequency of hand tremor, which indicates that hand tremor occurs more frequently in the case of an action tramer patient due to increased frequency of hand tremor. That is, when the hand tremor of the present invention is used, the amplitude of the hand tremor does not largely increase as shown in FIG. 4 (a) The amplitude of the treadmill is large and the treadmill is often out of the green line. When the frequency of the hand tremor is large and the frequency of the hand tremor suddenly changes, it can be diagnosed as an action treadmill, and more accurate diagnosis can be made. As shown in FIG. 5 (a), the settled phosphorus is formed to be less than 4% when exceeding the threshold value. However, referring to FIG. 5 (b) It makes it possible to distinguish. 6 (a), a normal person has a low vibration of 5 Hz or less (more specifically, a noise is generated in the hands 45 even if the hand 45 is still measured, which noise is less than about 3 Hz Referring to FIG. 6 (b), the action treadmill patient experiences hand tremor in the entire section, that is, in the high vibration region (the region with high hand tremor) and the entire region, .

The hand trembling method according to another embodiment of the present invention includes a step of moving a hand (S10), a step of measuring hand tremor (S20), a step of storing (S30), and a step of outputting (S40).

In one aspect of the present invention, step S10 of moving the hand involves moving hand 45 along guide line 40 provided at output 30 of the measuring device 100 (step S10 )to be. The user moves his / her hand along the guideline 40 so as to measure hand tremor.

The step of measuring hand trembling (S20) is a step (S20) of measuring hand tremor using the motion measuring unit 70 of the hand tremor measuring apparatus 100. The hand tremor measuring method is the same as the measuring apparatus 100 ). ≪ / RTI >

The storing step S30 is a step of storing the hand shaking frequency and amplitude in the hand trembling measuring apparatus 100 in the hand trembling measuring step S20. More specifically, it can be stored in a memory unit provided in the control unit 60 of the hand tremor measuring apparatus 100, and the frequency and the amplitude of the hand tremor are provided to the output unit 30 for the user to check.

Step S40 of outputting the hand shake frequency and amplitude through the output unit 30 is a step S40 of providing a criterion for determining whether the user is an action trammer patient by confirming hand shaking symptom to be. The hand movement frequency and amplitude provided to the output unit 30 may be provided in a graph form so that they can be easily recognized by the user.

In another aspect of the invention, the guideline 40 is provided in a circular shape. The guideline 40 is a device that allows a user to move his / her hands along the guideline 40, and may be provided in a circular shape. The guideline 40 can be used by using the content of the guideline 40 described above.

In another aspect of the present invention, the step of transmitting to the external terminal (S50) may further include transmitting the information about the hand tremor to the external terminal using the communication unit (50) provided in the hand tremor measuring apparatus (100) To the terminal. Information on hand tremor is hand tremor frequency and amplitude information. That is, by transmitting such information to an external terminal, the user can more systematically perform the action tramer diagnosis.

In another embodiment of the present invention, the hand tremor measurement in step S20 of measuring hand tremor is measured three or more times. Moving the hand three or more times along the guideline 40 allows the user to obtain a more accurate handwind measurement, thereby providing a more reliable measurement. In other words, moving the hand along the guide line 40 once or twice may cause the hand tremor less or more depending on the user's body condition, but if the hand tremor is measured more than 3 times, There is an effect that can be obtained.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
