경운기 시뮬레이터 운전자가 가상환경에서 교육에 몰입할 수 있도록 현실세계에 가상 물체를 겹쳐 보 여주는 증강 현실 기술을 구현하였다. 3D 카메라 입력 장치로부터 초당 30 frame 이상 속도로 경운기 모의 운전 장치의 영상을 획득한다. 획득된 현실 영상을 크로마키 처리하여 가상 현실과 결합하였다. RGB 영상의 HSI 변환 실험결과 색상 최대값 0.52, 최소값 0.153, 채도 최대값 0.57, 최소값 0.16, 명 도 최대값 1, 최소값 0.12이 크로마키 처리를 위해 최적값이었다. 본 연구에서는 키패드를 이용하여 크 로마키 처리된 현실 영상의 위치를 전·후·상·하·좌·우를 버튼으로 조정하여 초기 결합위치를 조정 할 수 있고 최종 조정된 값은 저장하여 유지 관리되도록 하였다. 이를 토대로 초당 30프레임 이상의 속 도로 가상현실과 크로마키 처리 영상을 결합한 증강현실 구현이 가능함을 보였다.

Recently, Product-Service System(PSS) is a rising paradigm that enables integration between products and services offering. Also, academic interests for product-service design using the house of quality (HOQ) have been emerged. the engineering characteristics of the HOQ are usually extracted by experts. However, as the new technologies were merged, it was difficult to find the optimum expert for extracting the engineering characteristics in the fusion technology. Therefore, this paper applies the topic modeling technique using patent data to extract the engineering characteristics which considers not only products features but also services characteristics. Also, a case study demonstrates the usefulness of our approach with augmented reality-head mounted display. It was conducted to make the HOQ with distinct four steps. First, the customer needs were collected through the latest device review from website and grouped into the representative customer needs. Second, the engineering characteristics of the augmented reality-head mounted display were extracted by using the US patent data of augmented reality head mounted display through the topic modeling technique. Third, the correlation degree of product - service characteristics was drawn by using the extracted topic’s cosine similarity. Finally, the relationship matrix of customer needs and engineering characteristics was filled with experts. After which we suggest product-service business concepts from HOQ. Main advantage is appeared from the result of this research paper is that it can provide the business concepts of the integrated product-services to reflect the customer requirements. This business concepts are utilized for the early phase in R&D planning.
