최근 3D 및 증강현실 기술이 발전함에 따라 사용자는 특수한 장비를 착용하지 않고서도 주변의 다양한 서비스 및 콘텐츠가 현실 세계와 결합되어 디스플레이 되며, 손의 감각과 인식에 따라 직접 상호작용하는 것을 요구한다. 이에 따라 기존 see-through HMD(Head Mounted Display)나 모니터 화면을 벗어나 실세계의 객체에 직접 증강된 현실을 보여주고 체험할 수 있는 프로젝션 기반 증강현실 기술의 중요성이 증대되고 있다. 본 고에서는 프로젝션 기반 증강현실을 구현하기 위한 출력보정, 추적 및 정합, 상호작용 및 사용자 인터페이스 기술에 대한 동향을 살펴본다. 더불어 산업, 의료, 교육 및 엔터테인먼트, 모바일 응용 등 각 분야에서 활용되고 있는 최근의 프로젝션 기반 증강현실 기술동향을 소개한다.
