In 2011, more than 2000 million smartphone users are in our country. As a result, consumer demand have been developed for a variety of applications, especially in the information service-related applications that combine location-based services and augmented reality in addition to related information for the virtual reality of things are rapidly increased. This paper analysed location-based services and augmented reality technology as related research and designed and implemented the system that provides the same environment as if the user is shopping and purchasing the items in the real world and offers the information characterizing the real situation combines location-based service and augmented reality which provides with an excellent reality in the smart phone environment. The proposed system in this paper is excellent in mobility, scalability and reality as a result of analysis of functions and services compared to web-based systems and has advantages to apply for the suitable system in ubiqutous environment which can be used in anytime and anywhere.

Augmented reality systems are widely used in the fields of entertainment, shopping, education, and training, and the augmented reality technology is gradually increasing in importance. When augmented reality technology is used for education or training, it must be possible to represent different virtual objects depending on the work stage even for the same marker. Also, since the training content varies depending on the situation, it is necessary to describe it using a training scenario. In order to solve this problem, we propose a scenario markup language for an augmented reality system that can create training content based on a scenario and connect it with an augmented reality system. The scenario markup language for augmented reality provides functions such as a method for connecting a scene, a marker and a virtual object, a method for grasping the state of equipment or sensor value, and a method for moving a scene according to conditions. The augmented reality scenario markup language can flexibly increase the usefulness and expandability of the augmented reality system usage method and content usage.

Museums are converging with digital technology to convey information to viewers in various ways. Augmented reality technology enhances virtual objects seamlessly in the real world, and provides a high sense of immersion and realism because it can use various senses of users in combination with information providing role of exhibits. However, the location-based augmented reality may cause the inaccurate registration of the virtual object with the real world due to the error of the GPS information, and the vision-based augmented reality can be enhanced at the position where the marker is placed. To solve this problem, we implemented the exhibition contents that interact with the real world by using the developed project tango. The exhibited contents were based on Lenovo Phab 2 Pro and Project Tango SDK in Unity 3D. Visitors were able to improve immersion and realism in exhibition contents, and it would be able to combine with various exhibition fields such as shopping malls as well as museums.

Augmented reality is derived from virtual reality that provides combined images of what users are watching and what computers are producing to improve the understanding of reality. As an effective method of applying this augmented reality technology in clothes shopping, in this paper we suggested an automatic vending machine as a sales medium, to seek a commercial application method, and developed a prototype.

The most important issue the online shopping mall for clothes is facing in the rapid growth of the online shopping mali is the high rate of the return of the goods alter purchase. The high rate of the return leads to the dissatisfaction md lack of trust from the consumers in the online shopping mall for clothes, which in turn leads to the bleak prospect for the online shopping mall for clothes as a result of the consumers' dissatisfaction. Although a type of online shopping mall using the cyber-fitting technology has emerged recently, it has succeeded only in provoking a visual interest, for it is also not satisfying the demand of the consumers by falling short in providing information. Thus, this research seeks for the resolutions of the problems related to the user-oriented online shopping. First of the resolutions is the development of a new prototype which the consumers can easily access; second is the visualization of the information using the 3D virtual-reality of he prototype through interface, which will help the consumers to make more accurate judgments. In other words, this study seeks to provide a type of prototype of an online shopping mall that meets the demand of the consumers using the 3D avatars, unlike the unilateral and conventional malls out there.

아바타(Avata)는 가상현실게임, 채팅, 사이버 쇼핑몰, 가상교육 등에서 사용자의 역할을 대신하는 애니메이션 웹 캐릭터의 의미로 사용되고 있다. 과거 네티즌들은 사이버공간의 익명성에 매료되었지만 이제는 자신을 표현하려는 욕구를 강하게 느끼게 되어 이 두 가지를 모두 충족시켜 주는 아바타가 청소년층을 중심으로 큰 인기를 얻고 있다. 그러나 현재 웹에서 제공되고 있는 아바타 생성 시스템들은 이미 완성된 아바타만을 제공하거나, 몇 가지의 부분별 캐릭터를 제공하여 사용자들이 조합하여 사용할 수 있도록 하고 있기 때문에 자신만의 독특한 개성을 표현하고자 하는 네티즌들을 만족시키지 못하고 있다. 따라서 본 논문에서는 XML/SVG를 사용하여 확대/축소가 가능하고, 그래픽 사용자 인터페이스를 통하여 쉽게 자신만의 독특한 아바타를 생성하기 위한 시스템을 제안하였다.

현대인들의 인터넷 사용률이 지속적으로 증가함에 따라 소비자들은 오프라인 매장에서 의류를 구매하기보다 인터넷 쇼핑을 통한 구매를 선호하게 되었다. 그러나 온라인 구매로 인해 정확한 스타일 확인 불가 및 확신할 수 없는 사이즈로 큰 불편함을 겪고 있다. 따라서 최근 가장 떠오르는 기술 중 하나인 AR을 실생활에 적용하여 사용자가 매장에 가지 않고 집에서도 편하게 자신의 스타일링을 확인할 수 있도록 하는 AR 피팅룸을 구현하여 솔루션을 제안하고자 한다. 본 프로젝트에서는 3D 표현을 위해 Kinect Xbox 카메라를 사용하여 사용자의 신체정보를 추출한 후 unity와의 연동을 통해 사용자에게 편리함을 제공할 수 있는 AR-fitting 시스템을 설계하였다. 선택한 옷을 가상으로 입어 볼 수 있는 쇼룸 형태의 서비스를 제공하며 제스처 인식을 통해 보다 편리한 의류 선택 및 사이즈 조절 등을 가능하게 하였다. 또한, 사용자의 입력 정보에 따른 사이즈 측정 결과를 제공함으로써 사용자의 의류 구매를 보다 효과적으로 만들어 줄 수 있을 것이다.

국내 섬유 및 패션산업은 세계적인 경쟁력을 갖추고 있으나 낙후된 디자인 기술, 비효율적인 생산관리, 다양한 고객 요구변화에 신속한 대응부족, 비효율적인 유통구조 등으로 인하여 경쟁력 향상에 많은 어려움을 겪고 있다. 따라서, 정부에서는 패션산업의 경쟁력강화를 위하여 대구지역을 중심으로 밀라노 프로젝트를 추진하고 있으나 대부분이 건물 신축 등 하드웨어적인 측면을 강조하고 있어 디자인 기술향상, 생산관리, 전자상거래 활성화 등 의류 및 패션산업 특성을 감안한 소프트웨어적인 전략 및 지원이 부족한 실정이다. 이에 따라, 본 연구에서는 3D 가상현실 기법을 의류 및 패션산업에 적합하게 개발하여 국내 패션산업의 세계화와 경쟁력강화에 기여하고자 한다. 주요 연구내용을 살펴보면, 소재의 2D, 3D 입체화 표현기술, 3D Virtual 표현기술, 2D, 3D Model 및 의상 DB 개발, Mapping 기술 등을 통합한 Virtual Dressing System(VDS)을 개발하고자 한다. VDS를 통하여 고부가가치 섬유의 신속한 개발, 디자인 기술 향상, 다자간 공동생산지원에 따른 효율적 생산관리가 가능할 것으로 기대된다. 또한, 웹기반 하에 Virtual Dressing System을 개발함으로써 의류 및 패션상품을 3D 형태로 입체적으로 볼 수 있게 함은 물론 가상 코디네이션 연출까지 가능케 함으로써 인터넷 쇼핑몰 상에서 의류, 패션상품의 판매 증대에 기여하고자 한다.

The health of feet is connected with individual's health and affects a man's activity. Shoes need to be designed to protect feet and to absorb the impact of land. Thus, design, comfort and economical efficiency are important factors of shoes. Consumers can choose suitable shoes for their feet in off-line shopping. However, in on-line shopping, because they can not wear shoes, compare to the off-line shopping, there are many problems in internet shopping. First, consumers can get limited information of shoes because they must search information of purchase without other's help. Second, because consumers can not get important information such as design, size and a comfort of wearing, they can not make a careful decision. Above these, the solution of user-oriented internet shopping is development of new type of prototype which is accessible to user and to offer visual information through 3D virtual reality.

This study investigates the characteristics of VR stores that emerged as new fashion communication media. Two case studies on Hyundai and eBay VR Department stores were conducted along with a discussion of the function and meaning of the fashion VR store. The results showed that both stores provide novel shopping experiences; however, the two were differentiated in terms of production method and technology implementation level. Functional aspects such as providing shopping efficiency and purchasing service was insufficient in both stores. Instead, they were complementing by means of product rotation, recommendation system, voice guidance, or linkage with an online shopping mall. In experiential aspects, both stores provided a strong sense of immersion. Hyundai VR store enhanced immersion with a high resolution image of a real offline store; however, it lacked in the ability to provide multisensory stimulation such as kinetic sense or auditory stimulation. The eBay VR Department store intensified the immersion experience by providing auditory stimulation as well as visual stimulation that enhanced the speed and distance sense through the utilization of animation. However, the extent of experience was limited in terms of agency and transformation because of the low interactivity found in both store systems.
