Summary: | The present invention relates to a finger motion capture interface device based on a three-dimensional magnetic sensor. According to the present invention, the finger motion capture interface device includes: a hand back fixing member fixing the back of a hand of a user; a first link member combined with the hand back fixing member, and including a first magnet installed in the body; a second link member including a first magnetic sensor for sensing a magnetic line generated from the first magnet; a first fixing member fixing the second link member to the first link member; a third link member combined with the first fixing member to be pivoted; a fourth link member including a spheroid joint part with a second magnetic sensor installed inside; a second fixing member fixing the fourth link member to the third link member; a fifth link member combined with the second fixing member and including a second magnet installed in the body; a finger wearing member combined with the fifth link member and including a finger placement part; and a computer system receiving a sensor coordinate value corresponding to a change of each magnetic line sensed through the first and second magnetic sensors, extracting yaw and pitch motions of each link based on the received value, and calculating a position of a finger of the user based on the extracted motions. Thus, the present invention is capable of accurately measuring motions and being manufactured at low costs.
본 발명은 3차원 자기 센서 기반의 손가락 모션 캡쳐 인터페이스 장치에 관한 것이다. 본 발명에 따른 3차원 자기 센서 기반의 손가락 모션 캡쳐 인터페이스 장치는, 사용자의 손등을 고정하기 위한 손등 고정부재와; 손등 고정부재에 결합되며, 몸체의 내부에는 제1 자석이 설치되어 있는 제1 링크부재와; 제1 자석에 의해 발생한 자력선을 감지하기 위한 제1 자기 센서가 설치되어 있는 제2 링크부재와; 제2 링크부재를 제1 링크부재에 고정시켜주는 제1 고정부재와; 제1 고정부재에 피봇(pivot) 운동 가능하도록 결합되는 제3 링크부재와; 내부에 제2 자기 센서가 설치되어 있는 구관절부가 형성되어 있는 제4 링크부재와; 제4 링크부재를 제3 링크부재에 결합 및 고정시켜주는 제2 고정부재와; 제2 고정부재에 결합되며, 몸체의 내부에는 제2자석이 설치되어 있는 제5 링크부재와; 제5 링크부재에 결합되며, 손가락 안착부가 형성되어 있는 손가락 착용부재; 및 제1 자기 센서와 제2 자기 센서에 의해 감지된 각각의 자력선 변화에 따른 대응하는 센서 좌표계 값을 수신하고, 수신된 센서 좌표계 값을 바탕으로 각 링크의 피치(pitch) 및 요(yaw) 움직임을 추출하며, 추출된 피치(pitch) 및 요(yaw) 움직임 값을 바탕으로 사용자의 손가락의 위치를 계산하는 컴퓨터 시스템을 포함한다. |
