Purchase of clothes has recently picked up pace at mobile fashion shopping malls. One of the biggest weak points is that consumers can't coordinate clothes. Since individuals increasingly want to make coordination, a fashion coordination system to satisfy the demand should be developed. As the technology of digital clothing which is about reproducing dresses using computer graphic has been activated in the fashion industry, many changes in consumers' life patterns and interests in fashion shopping malls are taking place. Some consumers are increasingly more keenly interested in shopping on the Internet and Smart phones than in offline stores. This study was conducted to understand production of iPhone-based augmented reality fashion fitting contents which is suitable for Koreans' body shape. This system is about designing and materializing UI(User Interface), an augmented reality fitting system, so that users can confirm if they look nice with those fashion items using Smart phones. A new fashion shopping method satisfying user convenience was suggested using the materialized system.

Interactive intervention of the human presenter is one of the important factors that make the visualization more effective. Rather than just showing the content, the presenter enhances the process of the information delivery by providing the context of visualization. In this paper, we define this as an augmented presentation. In augmented presentation concept, the presenter can facilitate presentation more actively by being fully immersed in the visualization space and reaching and interacting into digital information. In order to concrete the concept, we design presentation space that enables the presenter to be seamlessly immersed in the visualization. Also we increase the presenter's roles as a storyteller, controller and augmenter allowing the presenter to fully support communicative process between the audience and the visualization. Then, we present an augmented presentation system to verify the proposed concept. We rendered 3D visualization through a half-mirror film and a wall projection screen that are place in parallel and applied with stereoscopic images, then, spatially align the presenter inside the virtual visualization space. After that, we conduct a controlled experiment to investigate the subjective level of immersion and engagement of the audience to HoloStation compared to traditional presentation system. Our initial investigation suggests that the newly conceived augmented presentation has potential not only to enhance the information presentation but also to supports the delivery of visualization.

Place recognition is necessary for a mobile user to be provided with place-dependent information. This paper proposes real-time video based place recognition system that identifies users' current place while moving in the building. As for the feature extraction of a scene, there have been existing methods based on global feature analysis that has drawback of sensitive-ness for the case of partial occlusion and noises. There have also been local feature based methods that usually attempted object recognition which seemed hard to be applied in real-time system because of high computational cost. On the other hand, researches using statistical methods such as HMM(hidden Markov models) or bayesian networks have been used to derive place recognition result from the feature data. The former is, however, not practical because it requires huge amounts of efforts to gather the training data while the latter usually depends on object recognition only. This paper proposes a combined approach of global and local feature analysis for feature extraction to complement both approaches' drawbacks. The proposed method is applied to a mobile information system and shows real-time performance with competitive recognition result.

Over the past decade, building information modeling (BIM) has gained a foothold in the construction sector. However, as digital data generated in the virtual space of a computer environment, BIM-based data have an inherent limitation in their application efficacy under field conditions. To overcome this, the present study employs augmented reality (AR) to reduce the discrepancy between the digital data generated in virtual spaces and real-world conditions. We assessed the potential applicability of an AR-based interface by analyzing existing examples of Apple, Google, and Facebook, which reflect the recent developments of technologies focusing on user experience. We then proceeded with an AR study, restricting the scope of application to a mobile environment in which an efficient information transmission between a digital model and real life can take place. Object-oriented software engineering was employed to ensure an efficient implementation of a BIM-based AR system for campus space management (CSM) in a mobile environment. Finally, we conducted a module test to check the reliability of the CSM method by using an AR-based mobile system with a prototype of the model used in university campuses, and extracted and itemized the supplementary requirements for CSM by using BIM tools for running AR applications.

This study is intended to study the usage of augmented reality(AR) in the marketing field by classifying them into display and content types and analyzing the typical cases and characteristics. The market for AR has been on the increase and has been a big influence in the marketing field, resulting in the generalization of the term "AR marketing." By analyzing the marketing cases which use AR technology and organizing the frequency of use and characteristics, it is expected to contribute as a basic material for future studies on AR marketing. In this study, AR marketing cases are classified into different categories including display and contents. First, AR display category includes personal computers, mobile, public display, and projection display. AR contents category includes informative content, game contents, virtual experience, and visual effect. While investigating, it was found that the most used type of AR display was mobile, which has the advantage of not being limited by time and place and is also capable of one-on-one marketing with customers. The most used type of AR content was visual effect type, which evokes curiosity and is easily shared among people.

Recently, he trend of the game culture have been changed rapidly from offline games to online games. This change drives the advancement of online games, but it causes the standardization of the game culture. Few years ago, there was a rising interest in board games. Board cafes, place for playing board games, are spread over Korea rapidly because board games give players connectedness through direct social interactions that is lacking from online games. However, the board games lose their popularity because of their complex rules and expensive cost. In this paper, we would like to develop the system using Augmented Reality(AR) that could easy the problems caused by the complex rules of the board games.

Locative media is fundamentally different from traditional media in terms of being packed with user's space, place, and position nearby, which does not simply mean user's physical coordinates. This study has been started that I was drawn by the tendency of which current locative media contents are based on 'location-based information,' and closely related with 'Augmented Reality.' I wonder how media user's psychological experience/involvement are revealed when the media environment changes by the progress of technology. I wonder how media users perceive 'social presence' formed by locative media in current locative media environment. Particularly, the fact that user's perception of social presence formed in locative media conflicts with the previous computer-mediated communication(CMC)'s attributes deepened my curiosity. In this study, the idea of 'more-proper-construct' is suggested, the characteristics of social presence in current locative media is considered, and is investigated by qualitative methodology how the 'location-based' attributes and 'AR' contribute to forming the social presence.

Failure situations occur frequently in the industry, and the existing 2D-based manual for this purpose is not intuitive to understand and it is difficult to immediately interact with maintenance experts. In this paper, we propose a technology that enables workers to perform maintenance in real time with the help of experts without restrictions in time and place based on augmented reality when a failure situation occurs at a remote location. A local virtual human-based expert diagnoses a failure situation based on an adapted panoramic image of a remote failure situation while wearing an HMD headset, and gives instructions to a remote operator. In addition, in an augmented reality (AR) environment in a remote location, for the interaction between the operator and the expert, the HMD's microphone is used to create the expert's hand as well as verbal communication. You can use to point or draw a picture. If this technology is used, it is possible to overcome the limitations of the existing 2D-based manual, and to provide assistance in performing maintenance smoothly remotely even if an expert does not directly visit a remote location.
