In this paper we tried to overcome the limit of contents which occur when we implement the augmented reality technology adapted application on commercialized mobile system. First of all, we checked the requirement analysis of exclusive mobile system to support augmented reality. And then we designed and realized the mobile system based on this facts. Also we embodied augmented reality application based on NyARToolkit which assists augmented reality techniques. Finally the implemented contents operated properly in our exclusive mobile system. Consequently we confirmed the suitability and validity of our system through above test.

In this paper, we describe CAMAR Companoin, a context-aware mobile AR system that provides a user-adaptive assistance with an augmented picture according to the user's context in smart space. It recognizes physical objects and tracks the movement of those objects with a camera embodied to a mobile device. CAMAR Companion observes a mobile user's context, which is sensed by various kinds of sensors in environments, and infers user preference for the content in the situation. It recommends multimedia content relevant to the user's context. It overlays selected content over associated physical objects and enables the user to experience the content in a user-centric manner. Furthermore, we have developed the prototype to illustrate how our system could be used for a mobile user's well-being care applications in smart home environments. In this application, we found that our system could perceive a user preference even though a user's context is changed dynamically, and then adapt the multimedia content with respect to the user's context effectively. As such, the proposed user-adaptive system has the potential to play an important role in developing customized user interfaces in mobile devices.

Augmented Reality(AR) has been further developed through connectivity with Artificial Intelligence (AI), Big Data, the Internet of Things(IoT). The interest of AR in the advertising is on the increase. However, it needs to explore the use of AR technology in advertising based on user experience rather than the technical aspects. This study is very significant in that it is the exploratory study which provides guidelines in the field of utilizing AR, particularly based on direct user experience. In addition, through a quantitative survey, it checks the validity of the present study to verify the impact of utilitarian, experiential value of AR ad on brand attitude as consumer attitude. The characteristics of AR ad based on user experience through this study will provide guidance to utilize AR ad, utilizing AR technology in various fields, such as education and exhibitions in developing convergence contents that can provide practical value.

The marine life culture contents added with fun and learning factors are created in a 3D space, and the development of augmented reality contents concerning marine life resources in islands and the utilization method of experience-based learning are proposed. As a WYSIWYG-based authoring tool, an augmented reality authoring tool was made to easily use a authoring tool through a node structure and drag & drop. Marine life contents add the animation effect through a marker and event factors such as the change of modeling data, and also, they support real experience-based learning with the narration of marine life. Based on around 50 species of marine animals augmented reality contents, a marine animal AR book can be utilized as a textbook for elementary school classes, and as a 3D image education utilizing augmented reality, it enhances a learning effect by allowing realistic observation, various ways of thinking, and the maximum flow.

Smartphones provide users with environment for communication and sharing information and at the same time play an important role of mobile technology and mobile art development. Smartphone technology-related researches are being accelerated especially with the advent of mobile Augmented Reality(AR) age, but the studies on user participation that is essential for AR content industry were insufficient. In that regard, the assistance from mobile art area that has already developed these characteristics is essential. Thus, this article is to classify mobile art that has not been studied a lot domestically into feature phone usage and smartphone usage and to analyze each example case with the three most used methods. The usage of feature phones which use the sound and images of mobile devices can be divided into three: installation and performing methods, single channel video art method and five senses communication method. On the other hand, the usage of smartphones that use sensors, cameras, GPS and AR can be divided into location-based AR, marker-based AR and markerless AR. Also, as a result of examining mobile AR content utilization technology by industries, combined methods are utilized; tourism and game-related industries use location-based AR, education and medicine-related industries use marker-based AR, and shopping-related industries use markerless AR. The development of AR content industry is expected to be accelerated with mobile art that makes use of combined technology method and constant communication method through active participation of users. The future development direction of mobile AR industry is predicted to have minimized HMD, integration of hologram technology and artificial intelligence and make the most of big data and social network so that we could overcome the technological limitation of AR.

This paper proposes a educational content display system based on spatial augmented reality with a multi-touch screen for effective learning with intuitive interaction. It is hardly expected that the existing display systems have major learning effects because the user-system interaction can only be achieved through buttons or switches, In contrast, the system proposed by this paper ensures more effective interaction through the user's movement, not through buttons or switches. This system uses a spatial augmented reality method to display images, thereby attracting the users' attention. In addition, it ensures the effective dissemination of information by providing visual images that are more realistic.
