On Body Device는 웨어러블 기기와 VR·AR과 같이 신체에 부착하거나 착용하여 이용자와 가까운 위치에서 정보를 수집하고 전달하는 미디어 기기로 센싱, 알림, 시각·청각 정보 전달, 몰입형 콘텐츠 제공 등의 기능을 수행하고 있다. 현재 Watch, Band, Earwear, Glasses, HMD, Ring, Clip 등 다양한 폼팩터가 공존하고 있으며, 각 폼팩터는 입력·출력 방식, 연결 구조, 연산 구조, 배터리 및 무게 조건이 상이하다. 따라서 개별 제품의 성능 비교만으로는 On Body Device의 잠재력과 한계를 판단하기 어려워, 폼팩터별 기능 구현 방식과 구조적 제약을 함께 분석할 필요가 있다. 이에 본 보고서는 현재 시장에 출시된 On Body Device 제품들의 1)현재 기능 구현 수준을 평가하고, 2)개선·완화 가능성을 진단 및 3)On Body Device를 그룹화하여 각 그룹별 발전 방향을 살펴보았다.
