세컨드라이프 서비스 출현 이후, 사용자들은 가상세계에 만족하지 않고 이를 현실세계와 접목하려는 욕구가 증대되었다. 착용형 컴퓨터의 연구개발과 이를 활용한 개인의 일상생활 정보를 기록하는 연구가 진행되면서 현실세계의 이벤트를 인식할 수 있고, 이를 가상세계와 연계하여 서비스할 수도 있다. 또한 웹을 모든 서비스의 플랫폼으로 발전시키고자 웹 콘텐츠를 생성하는데 있어 사용자 참여를 증대시키고, 이를 개방하여 다른 사용자들과 공유하려는 웹2.0 패러다임이 대세이다. 향후, 가상세계 구축기술, 현실세계 표현기술, 라이프로깅 기술, 웹 기술 등의 발전과 더불어 이들 기술들이 어울려 실세계 웹이라는 새로운 형태의 기술을 만들어 낼 것이다. 본 고에서는 여러 서비스, 프로젝트 등을 통해 실세계 웹이 가지는 특징들을 추출하여 실세계 웹을 구축하는데 있어 필요한 요소 기술들을 살펴본다.
