스마트폰과 태블릿 등 모바일 기기의 사용이 보편화 되면서 증강현실(Augmented Reality)을 활용한 교육용 콘텐츠들이 개발되고 있다. 증강현실은 가상현실의 한 분야로 현실세계에 가상의 물체를 중첩함으로써 사용자에게 몰입감과 현실감 있는 정보를 제공하여, 사용자들에게 새로운 학습 경험을 확장시킬 수 있는 교육매체로 높은 관심을 받고 있다. 이에 본 논문은 훈민정음에 대한 교육콘텐츠를 스마트폰과 태블릿 PC에서 구현할 수 있도록 마커기반 증강현실 시스템을 개발하여 사용자들이 보다 쉽게 증강현실 교육용 콘텐츠를 사용할 수 있도록 하였다. 또한 게이피케이션 요소를 반영하여 보다 사용자들의 참여를 유도하고 몰입할 수 있도록 하였다.

박물관은 문화유산을 직접 확인할 수 있는 역사교육의 산실로서 매우 중요한 역할을 함에도 불구하고 관람객이 지속적으로 감소하여 왔다. 이에 대한 주요 요인으로는 전시내용의 고정 및 콘텐츠의 부족, 일방적인 정보 전달에 치중함으로써 관람객의 흥미 유발을 이끌어 내지 못하는 것을 들 수 있다. 일부 박물관은 모바일 장비를 이용한 가상 및 증강현실 관람을 도입하고 있으나, 기술적인 한계와 조작의 불편함, 몰입도의 부족으로 인해 큰 효과를 보지 못하고 있다. 본 논문에서는 관람객이 재방문하고 싶은 박물관을 만들기 위해 혼합현실을 기반으로 한 박물관 전시 콘텐츠를 제작한다. 제작된 콘텐츠는 혼합현실을 이용함으로써 가상, 증강현실 콘텐츠보다 몰입감과 현실감을 높일 수 있다. 또한, 관람객과 상호작용할 수 있도록 혼합현실 기반 웨어러블 기기를 사용함으로써 생생한 전시물 체험을 할 수 있다.

VR(Virtual Reality), which provides realistic services in virtual reality, provides a similar experience using a Head Mounted Display(HMD) device. When the HMD device is worn, it can not recognize the surrounding environment and it is easy to analyze the input pattern of the user with the Shoulder Surfing Attack(SSA) when entering the Personal Identification Number(PIN). In this paper, we propose a method to safeguard the user's password even if the hacker analyzes the input pattern while maintaining the user's convenience. For the first time, we implemented a new type of virtual keypad that deviates from the existing rectangle shape according to the VR characteristics and implemented the lock object for intuitive interaction with the user. In addition, a smart glove using the same sensor as the existing input devices of the VR and a PIN input method suitable for the rotary type are implemented and the safety of the SSA is verified through experiments.

In these days, space design is evolving to the mixed reality space where fused on-line and off-line. But, standard and measure of mixed reality space has not been suggested and there has been little research about media environment and expression method as a mixed system either. That's why here I suggest four media environments and their characteristics that act not only as a critical point in the mixed reality space based on ubiquitous technology but also as a standard for spatial discerning. 1) Real space that is a media environment only seen by human visual and tactical sense is evolving using expression methods like new materials based on digital technology and LED. 2) Augmented reality space is a media environment using information instruments is expressed with diverse 2D and 3D contents. 3) Cyber Space is a environment depends totally on media instruments is produced by perfect graphic information without any spatial and physical limitations. 4) Augmented cyber space is realized only through the displays in cyber studio and is a space where real objects and graphic information are mixed. Depending on the purpose of the experience, media environment and expressional characteristics of mixed reality space can be fused, blended, and mixed, and that can be realized to the intelligent information space where one can experience without spatial, visual, informational limitations. In the future, studies on physical characteristics of contents according to the media environment characteristics are necessary.

This paper is a study on the production of mixedeality contents by realizing AR coloring technology, virtual environment, and VR devices by realizing the interaction in virtual environment. In this study, we designed and produced the content from a fairy tale called 'Cinderella' to produce and demonstrate real mixed reality contents. 'Cinderella' shows 3D modeling in the virtual space using the Oculus Rift, and the modeled shoes can be lifted using Leap-Motion. It is a virtual augmented interaction content for exhibition and experience that can move a specific range from the foot on the treadmill. In this paper, we try to share the experience of creating new mixed reality game contents, which is a mixture of augmented reality and virtual reality technology, and continuation of universal use of this field.

가상현실 기술은 이제 컴퓨터가 생성한 환경과 사용자간의 자유로운 상호작용을 수행할 수 있도록 하는 것이 중요하게 되었다. 이러한 상호작용을 위해서는 시각 제시기뿐만 아니라 사용자가 가상환경에서 물리적인 힘을 느낄 수 있도록 하는 것이 중요하다. 본 논문은 가상환경에서 사용자에게 운동감을 제시할 수 있는 기기들의 소프트웨어적인 아키텍처를 제안하고, 또한 이러한 기기들을 연결하는 데 있어서 가상환경과 통합될 수 있도록 가상환경 서보와 힘 피드백 제시기간의 통신규약을 제시한다.

Virtual training is a kind of training that proceeds as if it were a real situation. In recent years, there has been a growing demand for experiencing a situation in which a virtual reality technology has not been experienced directly in the real world due to the rapid development of the technology. Especially, safety education is very necessary in Korea where safety accidents are caused by many disasters. Therefore, simulation of disaster response training using virtual reality is more urgent than ever. Although the automatic defibrillator is the medical device that is most needed to rescue patients with cardiac arrest, few people know how to use it. Therefore, there are very few cases where the use of automatic defibrillators has saved the patient's life in Korea. The proposed Automated External Defibrillator virtual training system enables immersive and experiential training in real situations and effective training at low cost.

Many researches are actively doing for digital implementation of traditional architectural heritage using multimedia and virtual reality technologies. In addition, various attempts are progressed to utilize the digitally implemented traditional architectural heritage as "contents." Nowadays, the digitally implemented traditional architectural heritage can be displayed on through the Internet and/or many multimedia appliances by these attempts. Recently, virtual reality technology, especially augmented reality technology, begins to grab the attention for digitally implementing architectural heritage. Augmented reality is a technology that makes possible to show the overlapped contents by piling up the virtual objects on the real world. Many studies for augmented reality are progressed because it has an advantage in interacting with virtual objects and information. This study proposes the method of digital implementation of traditional architectural heritage by using augmented reality technology. We presented the method and process of digital implementation of traditional architectural heritage with augmented reality technology. Moreover, digitally implemented traditional architectural heritage with augmented reality is compared with the contents implemented by other computer technologies. We, also, presented how to utilize the traditional architectural heritage contents by using augmented reality.

Virtual reality(VR) is known as immersive multimedia or computer-simulated reality, is a computer technology that replicates an environment, real or imagined, and simulates a user's physical presence and environment to allow for user interaction. Virtual realities artificially create sensory experience including sight, touch, hearing, and smell. Owing to the use of a single device in most VR contents, user have difficulty in manipulating user interface and game object. And also immersion of the game goes down because they can't see the mouse and keyboard in virtual space. In this paper, we design and implement the chess game to easily and accurately control user interface to improve the immersion in game.
