Abstract

The present invention relates to a technique for sensing user manipulation when the user's finger is moved to manipulate an external device. More specifically, the present invention relates to a technique wherein when a user's finger is moved to generate an input signal for an external device while wearing a ring-type user manipulation sensing device between the user's finger joints, the user manipulation sensing device identifies a corresponding user manipulation and notifies the external device. Particularly, the present invention relates to a technique wherein a user manipulation sensing device is configured to have one or more sensor rods, which are arranged to be erected in a vertically upward direction with respect to the upper surface of a control board at a distal end of the control board, the distal end being oriented toward a user's fingertip in a state where the device is worn on the user's finger, so that a large sensing area is formed even when the user's movement is minute. Accordingly, the present invention enables precise sensing of a movement even when the device is used by a user having difficulty in moving his or her arm or leg.

Description

손가락 마디 간 착용형 반지 타입의 사용자 조작 센싱 장치Finger-tipped wearable ring type user-operated sensing device
본 발명은 사용자가 외부 디바이스를 조작하기 위해 손가락을 움직일 때 그 사용자의 조작을 센싱하는 기술에 관한 것이다.The present invention relates to a technique for sensing a user's manipulation when the user moves a finger to manipulate an external device.
더욱 상세하게는, 본 발명은 손가락 마디와 마디 사이에 반지 타입으로 이루어진 사용자 조작 센싱 장치를 착용한 상태에서 외부 디바이스에 입력신호를 생성하기 위해 사용자 손가락을 움직이면 그 사용자 조작 센싱 장치가 해당 사용자 조작을 식별하여 외부 디바이스에 알려주는 기술이다.More specifically, in the present invention, when a user's finger is moved to generate an input signal to an external device while a user's manipulation sensing device having a ring type is worn between the fingertip and the node, the user manipulation sensing device performs the corresponding user manipulation. It is a technology that identifies and informs external devices.
특히, 본 발명은 사용자 조작 센싱 장치를 손가락에 낀 상태에서 사용자의 손가락 끝을 향하는 제어보드의 선단부에서 하나이상의 센서봉을 제어보드의 상면에 대해 연직 상방향으로 세워 배치함으로써 사용자의 미세한 움직임에도 센싱 영역이 크게 형성되도록 구성하였으며 이를 통해 팔다리의 움직임이 불편한 사용자가 이용하더라도 움직임을 정확하게 센싱할 수 있도록 하는 기술이다. Particularly, the present invention senses even minute movements of the user by placing one or more sensor rods vertically upward with respect to the upper surface of the control board at the tip of the control board facing the user's fingertips while holding the user's manipulation sensing device on the finger. It is configured so that the area is large and through this, it is a technology that can accurately sense the movement even if the user who is uncomfortable with the movement of the limbs.
일반적으로 사용자가 디바이스에 대해 조작신호를 입력시키기 위해서는 다양한 유저 인터페이스(예: 터치패드, 조이스틱, 마우스)가 필요하다. 그리고, 디바이스와 독립적으로 구비되는 유저 인터페이스로는 마우스, 조이스틱 등을 들 수 있다.In general, in order for a user to input an operation signal to a device, various user interfaces (eg, a touch pad, a joystick, and a mouse) are required. The user interface provided independently of the device may include a mouse and a joystick.
여기서, 마우스를 예로 들면 사용자가 마우스에 손을 올려놓고 조작함에 따른 입력신호가 디바이스에 전달되도록 하는 방식이다.Here, for example, a mouse is a method of transmitting an input signal to the device as the user puts his or her hand on the mouse.
그런데, 외상, 뇌손상에 의한 장애 등의 이유로 팔을 움직이기 어려운 환자나 근력이 떨어진 노인은 팔을 움직이는 동작이 불편하기 때문에 기존 마우스와 같은 장치를 조작한다는 것이 매우 어려운 일이다.However, it is very difficult to operate a device such as an existing mouse because a patient who is difficult to move an arm or an old man whose muscle strength is inferior due to a trauma or a disorder caused by a brain injury is uncomfortable.
이러한 불편함을 해소하기 위해 사용자의 손가락에 반지 형태로 끼워서 사용하도록 유저 인터페이스 장치가 다수 개시되었지만, 사용자 손가락의 미세한 움직임을 제대로 센싱하는 기술에 한계가 있거나 몸이 불편한 사용자에 대해서는 그 사용성이 떨어지는 단점이 있었다.Although many user interface devices have been disclosed for use in the form of a ring on a user's finger in order to solve such inconveniences, there is a limit in the technology for properly sensing the minute movement of the user's finger or the user's inconvenience for a user who is uncomfortable. There was this.
상기한 점을 해결하기 위해 몸이 불편한 사용자의 사용성이 양호하고 그러한 사용자 손가락의 미세한 움직임을 제대로 센싱할 수 있는 반지 타입의 사용자 조작 센싱 장치의 구현이 요구되고 있다.In order to solve the above-mentioned problem, there is a demand for an implementation of a ring-type user manipulation sensing device capable of satisfactory usability of a user who is uncomfortable and capable of properly sensing such fine movement of a user's finger.

도 1은 본 발명에 따른 반지 타입의 사용자 조작 센싱 장치를 사용자의 손가락 마디 사이에 착용한 예시도이다. 도 1을 참조하면, 본 발명은 반지 형태로 이루어져 사용자의 손가락 마디 사이에 착용된 상태에서 사용자의 손가락 움직임으로부터 사용자 조작을 센싱하기 위한 손가락 마디 간 착용형 반지 타입의 사용자 조작 센싱 장치로서, 링 밴드부(100), 스트레인 게이지부(200), 메인 콘트롤부(310), 모션 센서부(320)를 포함하여 구성된다.1 is an exemplary view of wearing a ring-type user operation sensing device between the user's finger joints. Referring to FIG. 1, the present invention is a ring type user manipulation sensing device of a wearable finger-type ring member for sensing a user's manipulation from a user's finger movement in a state in which a ring is formed between a user's finger nodes. 100, a strain gauge unit 200, a main control unit 310, and a motion sensor unit 320 are configured.
링 밴드부(100)는 사용자의 손가락에 끼워지도록 신축성 재질의 고리 형태로 이루어진다. 즉, 링 밴드부(100)는 다양한 사용자 손가락의 두께에 두루 적용될 수 있도록 외력에 대해 수축과 팽창이 자유로운 텐션을 갖는 합성수지재로 이루어짐이 바람직하다. Ring band portion 100 is made of a ring shape of elastic material to be fitted to the user's fingers. That is, the ring band portion 100 is preferably made of a synthetic resin material having a tension that is free to shrink and expand against external force so that it can be applied to the thickness of various user fingers.
스트레인 게이지부(200)는 링 밴드부(100)에 장착되며 링 밴드부(100)의 팽창 및 수축시 이와 연동하여 링 밴드부(100)의 테두리 방향을 따라 전기저항선의 길이가 변형되면서 상이한 저항값을 나타내도록 구성된다.The strain gauge part 200 is mounted on the ring band part 100 and exhibits different resistance values as the length of the electric resistance wire is deformed along the edge direction of the ring band part 100 in conjunction with the expansion and contraction of the ring band part 100. It is configured to.
메인 콘트롤부(310)는 스트레인 게이지부(200)의 저항값을 분석하여 링 밴드부(100)의 테두리 방향에 대한 수축 및 팽창에 따른 마우스 클릭 조작을 식별하도록 구성된다.The main control unit 310 is configured to analyze the resistance value of the strain gauge unit 200 to identify the mouse click operation due to the contraction and expansion of the edge direction of the ring band unit 100.
상세하게, 메인 콘트롤부(310)는 스트레인 게이지부(200)가 나타내는 저항값을 분석한 결과 그 분석한 저항값이 미리 설정한 임계치를 초과하면 마우스 클릭 조작이 이루어진 것으로 판단하도록 구성된다.In detail, the main control unit 310 is configured to determine that the mouse click operation is performed when the analyzed resistance value exceeds the preset threshold after analyzing the resistance value indicated by the strain gauge unit 200.
그리고, 메인 콘트롤부(310)는 스트레인 게이지부(200)가 나타내는 저항값을 분석한 결과 그 분석한 저항값이 미리 설정한 임계치 미만인 경우에는 사용자가 방향키 조작을 수행한 것으로 판단하고 모션 센서부(320)로부터의 모션 데이터에 기초하여 구체적인 방향키 조작의 내용을 식별하도록 구성된다.In addition, the main controller 310 analyzes the resistance value indicated by the strain gauge unit 200, and when the analyzed resistance value is less than a preset threshold, the main controller 310 determines that the user has performed a direction key operation. And the content of the specific direction key operation based on the motion data from 320.
즉, 사용자가 손가락을 움직이며 링 밴드부(100)가 움직이면서 스트레인 게이지부(200)가 변화하는 저항값을 나타낼 때, 이와 동시에 모션 센서부(320)도 그 움직임을 감지하게 된다.That is, when the user moves the finger and the ring band part 100 moves, the strain gauge part 200 shows a resistance value that changes, and at the same time, the motion sensor part 320 also detects the movement.
이 때문에 메인 콘트롤부(310)는 스트레인 게이지부(200)의 저항값에 따른 프로세싱을 우선하여 처리하고, 스트레인 게이지부(200)가 감지한 저항값이 미리 설정한 임계치 미만인 경우에 모션 센서부(320)가 생성한 모션 데이터를 기초로 프로세싱을 수행하도록 구성할 수 있다. 이를 통해, 메인 콘트롤부(310)의 연산량 부담을 경감하여 저전력 소모를 구현할 수 있게 된다.For this reason, the main control unit 310 prioritizes processing according to the resistance value of the strain gauge unit 200, and when the resistance value detected by the strain gauge unit 200 is less than a preset threshold, the motion sensor unit ( 320 may be configured to perform processing based on the generated motion data. Through this, the load of the calculation amount of the main controller 310 can be reduced to implement low power consumption.
이를 위해, 모션 센서부(320)는 사용자 조작 센싱 장치의 움직임을 감지하고 그에 따른 모션 데이터를 생성한다. 이때, 메인 콘트롤부(310)는 모션 센서부(320)가 생성한 모션 데이터를 기초로 방향키 조작을 식별한다.To this end, the motion sensor unit 320 detects the movement of the user manipulation sensing device and generates motion data accordingly. In this case, the main controller 310 identifies a direction key operation based on the motion data generated by the motion sensor 320.
그리고, 모션 센서부(320)는 도 1, 도 7, 도 8, 도 9에 나타낸 바와 같이 봉 타입의 센서, 즉 센서봉(321)을 하나이상 구비할 수 있다. 모션 센서부(320)는 하나이상의 센서봉(321) 및 그에 관련된 회로를 포함하는 구성이다.The motion sensor unit 320 may include one or more rod-type sensors, that is, sensor rods 321, as shown in FIGS. 1, 7, 8, and 9. The motion sensor unit 320 is configured to include one or more sensor rods 321 and circuits related thereto.
여기서, 각 센서봉(321)은 링 밴드부(100)를 착용한 사용자의 손가락 끝을 향하는 제어보드(300)의 선단부에서 도 1, 도 7, 도 8, 도 9에서와 같이 제어보드(300)의 상면에 대해 연직 상방향으로 세워져 배치된다. 센서봉(321)의 배치에 대해서는 도 4를 참조하여 상세하게 후술한다.Here, each sensor rod 321 is the control board 300 as shown in Figure 1, 7, 7, 8, 9 at the tip of the control board 300 toward the fingertip of the user wearing the ring band portion 100 It is placed upright in the vertical direction with respect to the top surface. The arrangement of the sensor rods 321 will be described later in detail with reference to FIG. 4.
도 2는 본 발명에서 스트레인 게이지부(200)가 늘어난 상태를 확대하여 도시한 도면이고, 도 3은 본 발명에서 스트레인 게이지부(200)가 줄어든 상태를 확대하여 도시한 도면이다.2 is an enlarged view showing a state in which the strain gauge unit 200 is stretched in the present invention, and FIG. 3 is an enlarged view illustrating a state in which the strain gauge unit 200 is reduced in the present invention.
먼저, 도 2를 참조하면, 사용자가 손가락을 구부리면 손가락 직경이 커지게 되는데 그에 따라 손가락에 끼워진 링 밴드부(100)의 직경이 늘어나 있는 상태가 도시되어 있다. 이때에는 링 밴드부(100)의 직경이 증가함에 따라 링 밴드부(100)가 테두리 방향을 따라 팽창하게 되고 이와 연동하여 링 밴드부(100)에 장착된 스트레인 게이지부(200)도 링 밴드부(100)의 테두리 방향으로 늘어난다. First, referring to FIG. 2, when a user bends a finger, a finger diameter increases, and accordingly, a state in which the diameter of the ring band part 100 fitted to the finger is increased is illustrated. At this time, as the diameter of the ring band part 100 increases, the ring band part 100 expands along the rim direction, and the strain gauge part 200 mounted on the ring band part 100 also interlocks with the ring band part 100. Stretches in the direction of the border.
이때, 스트레인 게이지부(200)의 저항선(210)도 자신의 길이방향을 따라 늘어나면서 저항선(210) 자체의 저항값이 증가하게 된다. 메인 콘트롤부(310)는 저항선(210)의 양단에 구비된 터미널(220)과 통전되도록 연결되어 그 저항선(210)의 저항값이 증가하는 상태를 감지할 수 있으며, 그에 기초하여 사용자가 손가락을 구부렸다는 사실을 식별할 수 있게 된다.At this time, the resistance line 210 of the strain gauge unit 200 also increases along its longitudinal direction, thereby increasing the resistance value of the resistance line 210 itself. The main controller 310 may be connected to the terminal 220 provided at both ends of the resistance wire 210 so as to sense a state in which the resistance value of the resistance wire 210 increases, based on which the user touches a finger. You'll be able to tell that it's bent.
또한, 도 3을 참조하면, 사용자가 손가락을 펴면 손가락 직경이 작아지게 되는데 그에 따라 손가락에 끼워진 링 밴드부(100)의 직경도 줄어들어 있는 상태가 도시되어 있다. 이때에는 링 밴드부(100)의 직경이 감소함에 따라 링 밴드부(100)가 테두리 방향을 따라 수축하게 되고 이와 연동하여 링 밴드부(100)에 장착된 스트레인 게이지부(200)도 링 밴드부(100)의 테두리 방향을 따라 감소한다.In addition, referring to Figure 3, when the user stretches the finger is the diameter of the finger is reduced, so that the diameter of the ring band portion 100 fitted to the finger is also shown is reduced. At this time, as the diameter of the ring band part 100 decreases, the ring band part 100 contracts along the rim direction, and the strain gauge part 200 mounted on the ring band part 100 also interlocks with the ring band part 100. Decrease along the border direction.
이때, 스트레인 게이지부(200)의 저항선(210)도 자신의 길이방향을 따라 수축되면서 저항선(210) 자체의 저항값이 감소하게 된다. 메인 콘트롤부(310)는 저항선(210)의 양단에 구비된 터미널(220)과 통전되도록 연결되어 그 저항선(210)의 저항값이 감소하는 상태를 감지할 수 있으며, 그에 기초하여 사용자가 손가락을 폈다는 사실을 식별할 수 있게 된다.At this time, the resistance line 210 of the strain gauge unit 200 also shrinks along its length direction, thereby reducing the resistance value of the resistance line 210 itself. The main controller 310 may be connected to the terminal 220 provided at both ends of the resistance wire 210 so as to sense a state in which the resistance value of the resistance wire 210 decreases. You can identify the fact that
이처럼 스트레인 게이지부(200)의 저항선(210)이 자신의 길이방향이 링 밴드부(100)의 테두리 방향을 향하도록 구성함이 바람직하다. 이를 통해, 메인 콘트롤부(310)는 손가락의 움직임에 연동하여 직경이 증감하는 링 밴드부(100)로부터 스트레인 게이지부(200)의 미세한 저항값 변화를 감지할 수 있다.As such, it is preferable that the resistance wire 210 of the strain gauge part 200 is configured such that its length direction is directed toward the edge of the ring band part 100. Through this, the main controller 310 may detect a slight change in the resistance value of the strain gauge unit 200 from the ring band unit 100 whose diameter increases or decreases in response to the movement of the finger.
도 4는 본 발명에 따른 사용자 조작 센싱 장치를 착용한 상태에서 손가락을 상하 방향으로 움직이는 과정을 도시한 사용상태도이고, 도 5는 본 발명에 따른 사용자 조작 센싱 장치를 착용한 상태에서 손가락을 좌우 방향으로 움직이는 과정을 도시한 사용상태도이다.4 is a state diagram illustrating a process of moving a finger up and down in a state of wearing a user manipulation sensing device according to the present invention, and FIG. 5 illustrates a left and right direction of a finger in a state of wearing a user manipulation sensing device according to the present invention. It is a state diagram showing the process of moving to.
도 4와 도 5를 참조하면, 모션 센서부(320)는 메인 콘트롤부(310)가 탑재되는 제어보드(300)에 설치되며 사용자가 링 밴드부(100)를 착용한 상태에서 사용자의 손가락 끝을 향하는 제어보드(300)의 선단부에 설치됨이 바람직하다. 특히, 도 4에 도시된 바와 같이 제어보드(300)의 선단부에서 연직 상방향으로 제어봉(321)을 하나이상 설치함으로써 특히 상하 방향으로 이루어지는 손가락의 섬세한 움직임을 감지하도록 구성하는 것이 바람직하다.4 and 5, the motion sensor unit 320 is installed on the control board 300 on which the main control unit 310 is mounted, and the user ends the fingertips of the user while wearing the ring band unit 100. It is preferably installed at the front end of the control board 300 facing. In particular, as shown in FIG. 4, it is preferable to configure one or more control rods 321 in the vertical upward direction at the distal end of the control board 300 so as to sense delicate movements of the finger made in the vertical direction.
후술하는 도 6을 참고하면, 상하 방향으로 손가락을 많이 꺽게되면 마우스 클릭 조작으로 식별된다. 따라서, 방향키 조작을 위하여 이루어지는 도 4에서와 같은 상하 방향의 움직임은 상대적으로 작은 범위에서 이루어져 하며, 마우스 클릭 조작과 구분하기 위해 섬세한 센싱이 요망된다. 특히, 몸이 불편한 사용자가 손가락을 조작하는 경우에도 이를 섬세하게 감지할 필요하게 있다. 이러한 점을 감안하여 본 발명에서는 모션 센서부(320)의 구성 및 배치에 대해 아래에서 설명하는 바와 같이 2가지를 고려하였다.Referring to FIG. 6 to be described later, when a finger is folded up and down in a vertical direction, it is identified as a mouse click operation. Therefore, the up and down movements as shown in FIG. 4 made for the manipulation of the direction keys are made in a relatively small range, and delicate sensing is required to distinguish them from the mouse click manipulation. In particular, it is necessary to detect this delicately even when the user who is inconvenient to manipulate the finger. In view of this point, the present invention considered two configurations and arrangements of the motion sensor unit 320 as described below.
첫째로, 손바닥에 가장 인접하는 손가락의 관절 부분을 손가락의 회전 기준점(S)으로 보면, 그 회전 기준점(S)으로부터 가장 먼 거리에 위치한 제어보드(300)의 선단부에 모션 센서부(320)를 배치하였다. 이를 통해, 회전 기준점(S) 대비 작은 각도의 움직임에도 모션 센서부(320)는 큰 폭으로 이동하게 되고 그에 따라 모션 센서부(320)는 그 움직임을 확실하게 감지할 수 있다.First, when the joint portion of the finger closest to the palm is viewed as the rotation reference point S of the finger, the motion sensor unit 320 is placed at the tip of the control board 300 located farthest from the rotation reference point S. Placed. As a result, the motion sensor unit 320 moves largely even with a small angle of movement relative to the rotation reference point S, and thus the motion sensor unit 320 can reliably detect the movement.
둘째로, 제어보드(300)의 선단부에서 연직 상방향으로 세워 하나이상의 센서봉(321)을 설치하였다. 센서봉(321)이 도 4에서와 같이 세워져 배치됨에 따라 회전 기준점(S) 대비 손가락이 아주 작은 각도로 움직이는 경우에도 모션 센서부(320)는 더욱 큰 폭으로 이동하게 되고 그에 따라 모션 센서부(320)는 그 움직임을 보다 정확하게 감지할 수 있다. Secondly, vertically upward from the tip of the control board 300 One or more sensor rods 321 were installed. As the sensor rod 321 is placed upright as shown in FIG. 4, even when the finger moves at a very small angle with respect to the rotation reference point S, the motion sensor unit 320 moves to a greater width, and thus the motion sensor unit ( 320 may detect the movement more accurately.
한편, 센서봉(321)을 제어보드(320)의 선단부에서 연직 상방향으로 세워 설치하는 대신 제어보드(300)를 상당히 길게 연장한다면 상하 방향의 움직임에 대해 유사한 수준의 센싱 감도를 얻을 수 있을 것이다. 하지만, 이러한 구성에 의하면 사용자 조작 센싱 장치를 손가락에 낀 상태에서 생활하기가 매우 불편해진다. 본 발명은 팔다리의 움직임이 불편한 사용자가 일상 생활에서 활용하기 위한 장치이므로 손가락에 끼고 생활하기에 적합해야 한다. 이에, 본 발명에서는 제어보드(300)를 길게 연장한다는 것이 바람직하지 않다고 판단하며, 그 대신 센서봉(321)을 제어보드(320)의 선단부에서 연직 상방향으로 세워 설치하는 구성을 채택하였다.On the other hand, instead of installing the sensor rod 321 upright in the vertical direction from the front end of the control board 320, if the control board 300 extends considerably long will be able to obtain a similar level of sensitivity for movement in the vertical direction . However, according to such a configuration, it becomes very inconvenient to live in a state where the user manipulation sensing device is put on the finger. Since the present invention is a device for the user who is uncomfortable with the movement of the limbs in everyday life, it should be suitable for living on the fingers. Therefore, in the present invention, it is determined that it is not preferable to extend the control board 300 for a long time, and instead, the sensor rod 321 is adopted to be installed upright in the vertical direction at the distal end of the control board 320.
이상과 같은 구성을 통하여, 도 4와 도 5에서와 같이 사용자가 손가락을 상하좌우로 움직이면 메인 콘트롤부(310)는 모션 센서부(320)가 생성한 모션 데이터에 기초하여 방향키 조작을 식별하게 된다.Through the above configuration, as shown in FIGS. 4 and 5, when the user moves the finger up, down, left, and right, the main control unit 310 identifies the direction key operation based on the motion data generated by the motion sensor unit 320. .
바람직하게는 일차로 스트레인 게이지부(200)가 나타내는 저항값을 분석하여 그 저항값이 미리 설정한 임계치 이상인 경우라면 후술하는 도 6에 따른 마우스 클릭 조작으로 판단하고, 그 저항값이 임계치 이하인 경우라면 방향키 조작을 위한 상하좌우 움직임으로 판단한다. 방향키 조작을 위한 상하좌우 움직임으로 판단한 경우에, 그 구체적인 움직임 방향은 모션 센서부(320)가 생성한 모션 데이터에 기초하여 식별하게 된다.Preferably, if the resistance value indicated by the strain gauge unit 200 is first analyzed and the resistance value is greater than or equal to a preset threshold, it is determined by the mouse click operation according to FIG. 6 to be described later, and the resistance value is less than or equal to the threshold value. Judging by up, down, left and right movement for direction key operation. When it is determined that the user moves up, down, left, or right for the direction key manipulation, the specific movement direction is identified based on the motion data generated by the motion sensor unit 320.
도 6은 본 발명에 따른 사용자 조작 센싱 장치를 착용한 상태에서 마우스 클릭 조작을 수행하는 과정을 도시한 사용상태도이다.6 is a state diagram illustrating a process of performing a mouse click operation while wearing a user manipulation sensing device according to the present invention.
도 6에서와 같이 사용자가 손가락의 마디를 하방향으로 충분히 꺾는 행동, 본 발명에서 정의한 소위 '마우스 클릭' 동작을 수행하면 메인 콘트롤부(310)는 스트레인 게이지부(200)가 나타내는 저항값을 분석하여 그 저항값이 미리 설정한 임계치를 초과함을 식별하게 된다.As shown in FIG. 6, when the user performs an action of bending the node of the finger sufficiently downward, the so-called 'mouse click' operation defined in the present invention, the main control unit 310 analyzes the resistance value indicated by the strain gauge unit 200. The resistance value is identified to exceed the preset threshold.
이 경우 메인 콘트롤부(310)는 사용자가 마우스 클릭 조작을 수행한 것으로 식별하게 된다.In this case, the main controller 310 identifies that the user has performed a mouse click operation.
도 7 내지 도 9는 본 발명의 세가지 실시예에 따른 스트레인 게이지부의 배치상태도를 나타낸다. 7 to 9 are diagrams showing the arrangement state of the strain gauge unit according to the three embodiments of the present invention.
먼저 도 7과 도 8을 참조하면, 스트레인 게이지부(200)는 사용자가 링 밴드부(100)를 착용한 상태에서 사용자의 중지를 향하는 링 밴드부(100)의 측부에 설치됨이 바람직하다. 이는 몸이 불편한 사용자가 손가락에 본 발명에 따른 반지 타입의 사용자 조작 센싱 장치를 착용한 상태에서 스트레인 게이지부(200)가 손의 바깥쪽으로 노출되지 않도록 하여 그 손상을 방지할 수 있다.First, referring to FIGS. 7 and 8, the strain gauge part 200 is preferably installed at the side of the ring band part 100 facing the user's middle finger while the user wears the ring band part 100. This prevents the user from being uncomfortable so that the strain gauge part 200 is not exposed to the outside of the hand while the user wears the ring-type user manipulation sensing device according to the present invention.
이때, 도 7은 사용자의 왼손 엄지손가락에 착용하기 위한 것으로 왼손잡이가 사용하기에 적합하고, 도 8은 사용자의 오른손 엄지손가락에 착용하기 위한 것으로서 오른잡이가 사용하기에 적합하다.At this time, Figure 7 is to be worn on the thumb of the user's left hand is suitable for use by the left hand, Figure 8 is to be worn on the thumb of the user's right hand is suitable for use by the right hand.
다음으로 도 9를 참조하면, 스트레인 게이지부(200)는 제어보드(300)와 대향하는 링 밴드부(100)에 설치될 수 있다. 링 밴드부(100)가 사용자의 손가락에 착용된 상태에서 손가락을 구부리거나 펼때 가장 많이 팽창되거나 수축되는 부분이 제어보드(300)와 대향하는 위치이기 때문이다.Next, referring to FIG. 9, the strain gauge part 200 may be installed in a ring band part 100 that faces the control board 300. This is because the most inflated or retracted portion when the ring band 100 is bent or extended with the finger worn on the user's finger is a position facing the control board 300.
사용자의 손가락이 소정 범위 움직일 때 링 밴드부(100)가 상대적으로 많이 팽창되거나 수축된다면 그만큼 몸이 불편한 사용자가 손가락을 조금 움직여도 그 움직에 따른 사용자 조작을 정확하게 센싱할 수 있게 된다.If the ring band part 100 is relatively inflated or contracted when the user's finger moves within a predetermined range, even if the user who is uncomfortable moves the finger a little, the user's manipulation according to the movement can be accurately sensed.
