Beschreibung
Zusammenfassung:	The present invention provides an indoor location tracking system using a geomagnetic sensor, including: a magnetic field computing unit to compute a magnetic field value based on geomagnetic data received from a geomagnetic sensor; a location tracking unit to obtain changes in the location of a user based on the temporal change of the magnetic field value computed by the magnetic field computing unit; and a GUI generation unit to display the location change of the user obtained by the location tracking unit on a map screen on an indoor space. 실내 위치 추적 시스템으로서, 지자계 센서로부터 수신된 지자계 데이터에 기반하여 자기장 값을 연산하는 자기장 연산부; 상기 자기장 연산부에 의해 연산된 자기장 값의 전후(前後) 변화에 기반하여 사용자의 위치 변화를 획득하는 위치 추적부; 및 상기 위치 추적부에 의해 획득된 사용자 위치 변화를 실내 공간에 관한 맵 화면 상에 반영하여 표시하는 GUI 생성부를 포함하는 실내 위치 추적 시스템이 제공된다.
