Advances in 3D garment simulation technology contribute greatly to consumers becoming more immersed in movies and games by realistically expressing the garments the characters in the movie or game are wearing. The fashion industry has reached a point where it needs to maximize efficiency in production and distribution to go beyond time and space in order to compete on the global market. The processes of design and product development in the fashion industry require countless hours of work and consume vast resources in terms of materials and energy to repeat sample production and assessment. Therefore, the design and product development tools and techniques must aim to reduce the sample making process. Therefore, this study aims to study a case for comparing the real garment sample making process to the virtual garment sample making process. In this study, we have analysed the differences between the real and virtual garment making processes by choosing designated patterns. As we can see from the study results, the real and virtual garments generally are made through similar processes in manufacturing, while the time consumed for each shows great variation. In real garment making, scissoring and sewing require the greatest number of work hours, whereas in virtual garment making, most of the time was spent in the simulation process.

건물 및 주택의 가구배치나, 인테리어 디자인 등을 신규로 구성하거나 재배치하는 것은 고비용의 작업일 뿐만 아니라, 사용자가 정확히 판단하기 어렵다. 가상현실 시스템을 적용하면 공간적, 물리적 제약에 의해 현실 세계에서는 직접 경험하지 못하는 상황을 간접 체험할 수 있어 재배치에 대한 비용 및 시행착오의 오류를 줄일 수 있다. 따라서 본 논문에서는 EON Studio를 이용하여 건물 내부의 인테리어를 바꿔가며 디스플레이 할 수 있는 실내 인테리어 시스템 프로토타입을 제시하고자 한다. 현실 건물 내부와 가구를 EON Studio를 통해 구축한 후 회전 및 이동을 통해 재배치 도록 하였다. 구현된 시스템을 통해 제안된 인터페이스가 공간 배치 응용 분야에서 유용성 이 있음을 확인하였다.

Today's Virtual Reality(VR) technology has become considerably more affordable and sophisticated with rapidly advancing computer technology. Photo-realistic visual representations along with real-time interactivity are now achievable without special programing knowledge and expensive equipment. The purpose of this paper is to establish how simple, credible user testing methods based on VR simulations can be utilized to improve design decision making towards more sensible design solutions for end-users. Results of a case study demonstrate the value of potential user-testing feedback in a simulated 3D virtual service space, i.e., restaurant interior. User feedback from the VR simulation includes preferences in table location, privacy, and values of seating preferred tables. A new design framework incorporating an empirical testing method for service spaces is presented. The overall design process, the development of the VE, and the user testing method and findings are discussed. This study provides useful guidances for future efforts in the areas where such technology may benefit to understand end-user feedbacks in design process.
