본 연구에서는 무구속적으로 사용자의 활동상태를 모니터링하고 이를 기반으로 산만도를 추정하기 위한 연구를 수행하였다. 사용자의 활동상태 모니터링을 위해서는 키넥트 센서를 활용하여 머리에서의 관절정보와 어깨관절정보를 검출하고, 각 검출지점의 시간당 좌표변화를 인덱스화하여 움직임 변화정도를 측정하였다. 이러한 움직임정보로부터 산만도의 추정을 위하여 움직임의 빈도와 움직임의 강도를 분석하고 이로부터 산만도를 추정하기위한 인덱스를 개발하였다. 실제 사용자의 활동상태로부터 추출된 움직임정보 및 산만도 추정인덱스의 모니터링을 위하여 PC기반의 모니터링 및 스마트폰기반의 어플리케이션을 구현하였다. 구현된 시스템의 성능평가를 위하여 키넥트를 이용한 산만도 추정 어플리케이션과 동시에 비디오 계측을 통해 움직임의 정도에 따른 산만도 추정식의 결과를 비교분석한 결과 개발된 산만도 추정시스템과 비디오분석결과의 상관관계가 높음을 실험으로 확인하였다.
