Abstract

Bad posture triggers spinal diseases by forming a twisted or crooked body. Therefore, it is vital for modern people mostly living a sedentary lifestyle to have correct posture. In this paper, we construct a reasonably priced motion capture system requiring less preparation time and measurement space by using small-sized and lightweight micro electro-mechanical systems-based wireless inertial sensors to address the problems with the existing motion capture system. In addition, we have acquired and analyzed 4-joint motion data. The analysis results show that the motion data of four joints acquired through the embodied system can be applied to the self-coaching system, and users can employ the system for spinal disease diagnosis themselves.

잘못된 자세는 비뚤어진 체형을 형성하며, 척추질환을 유발한다. 그러므로 앉아있는 시간이 긴 현대인들에게 바른 자세를 유지하도록 하는 것은 매우 중요하다. 본 논문에서는 자세 교정을 위한 척추질환 예방용 4개 관절 기반 모션캡쳐 시스템을 구축하였다. 구축한 시스템은 기존 모션캡쳐 시스템의 문제를 해결하기 위해, 작은 크기와 가벼운 무게를 갖는 MEMS 기반 무선 관성센서를 이용하여 사전 준비 시간이 짧고, 측정 장소에 구애받지 않는 저렴한 모션캡쳐 시스템을 구현하였다. 구축한 시스템을 통해 4개 관절의 모션 데이터를 취득, 분석하였다. 분석 결과, 구현한 시스템을 통해 취득한 4개 관절의 모션 정보를 척추질환 예방용 셀프-코칭 시스템에 적용할 수 있으며, 사용자 스스로 척추질환을 판단하는데 활용 가능함을 확인하였다.
