최근 파노라마 영상과 같이 광각 카메라를 이용하여 인간의 시야각 이상의 범위를 사용자에게 제공하는 영상들을 쉽게 접할 수 있다. 초고해상도를 갖는 파노라마 이미지를 단일 디스플레이에 표출하게 되면 영상의 크기가 축소되고, 모니터 크기의 한정성으로 실감 시청에 불편함을 느끼고 있다. 본 논문에서는 객체 검출(object detection)을 이용한 사용자 위치정보와 관심영역(ROI)를 이용한 영상 제어를 이용하여 이러한 불편함을 느끼는 파노라마 영상을 해결한다. 따라서 사용자는 HMD(Head Mounted Display)와 같은 장치를 착용하지 않고 편리하고 실감 적으로 파노라마 영상을 시청할 수 있으며, 본 논문을 응용한 디스플레이와 상호작용을 통해 다양하고 더욱 실감 적으로 영상을 제어할 수 있는 기대효과를 가진다.

In modern recently technology, 3D-Audio is used to enhance immersion in Virtual Reality. This includes interest of people about VR and AR, which related to the field of computer graphics. In fact, a lot of research has been carried out in recent years into a 3D sound field. However, the existing 3D generator device used for virtual reality does not contain Doppler effect occurred by the sound comes to or leave from a listener, while an angle from the listener and the altitude of the source sound are applied. Therefore, this paper present 3D real sound utilizing Doppler effect with spatial-rotation-speaker. We map the source sound in 3D-space into a real space where a user stays and present 3D real sound by manipulating with rotation angle, phase difference, sound output volume of the sound in 3D-space, according to the location of a virtual source sound. Utilizing both natural Doppler effect of rotating sound that is occurring by spatial-rotation-speaker and artificial Doppler effect generated by frequency-modulation of sound quality could improving the virtual reality for sound condition for perspective listening.

In recent years, the Augmented Reality Technology is improving in order to support the user-oriented interaction depending on growing trend in smart phones. In this paper, we present the Realistic Experience App. Contents which help the smart phone users experience the real situations by using the Object Recognition Technology of the tourist attractions and the users' location information. The developed system pinpoints both the location of the user and that of the tourist spot object through the GPS of the smart phone and the information of Beacon, providing the realistic experience contents about the tourist attraction after estimating the distance and the direction between the user and the place. The Realistic Experience App. Contents are expected not only to impress the culture of Jeju on the tourists but also to increase the potential to uncover the unknown tourist attractions and improve the image of Jeju as one of the best sightseeing cities.

The recent development in multimedia technology such as audio technology needs high quality audio system. Especially, Real Audio Technology is to be developed to play realistic sound. To meet this demands, researches on 3-Dimensional Audio which provides realistic audio effect in virtual reality and augmented reality are conducted. In this paper, how to provide realistic audio effect by using better audio technologies in augmented reality was investigated. In the study, the movements of the 3-Dimensional model on the markers were used to provide the sense of reality in virtual and real world. Namely, the sound was modified according to the movement of the model. The change in distance and angle of the model affected the sound volume and the pitch.

Technologies for video reality (e.g., 3D displays, vibration, surround sound, etc.) utilize various sensory input and many of them are now commercialized. However, when it comes to the use of olfaction for video reality, there has not been much progress in both practical and academic respects. Because olfactory sense is tightly associated with human emotion, proper use of this sense is expected to help to achieve a high degree of video reality. This research tested the effects of a video's color-temperature related scent on reality improvement when the video does not have apparent object (e.g., coffee, flower, etc.) which suggest specific smell. To this end, we had participants to rate 48 scents based on a color-temperature scale of 1,500K (warm)-15,000K (cold) and chose 8 scents (4 warm scents, 4 cold scents) which showed clear correspondence with warm or cold color-temperatures (Expt. 1). And then after applying warm (3,000K), neutral (6,500K), or cold (14,000K) color-temperatures to images or videos, we presented warm or cold scents to participants while they rate reality improvement on a 7-point scale depending on relatedness of scent vs. color-temperature (related, unrelated, neutral) (Expts. 2-3). The results showed that participants experienced greater reality when scent and color-temperature was related than when they were unrelated or neutral. This research has important practical implications in demonstrating the possibility that provision of color-temperature related scent improves video reality even when there are no concrete objects that suggest specific olfactory information.

Recently, Augmented Reality(AR) technologies have been emerged, which shows the types of digital contents integrating real and virtual worlds. To maximize the effect of AR technology, tangible user interface, which enables users to interact with the contents in the same way in which they manipulate objects in real world, is applied. In particular, we expect that the technologies are able to enhance learners' interests and degree of immersion, and produce new learning contents in order to maximize the effect of learning. In this paper, we propose a learning system for scientific experiments with multi-touch screen and tangible user interface. The system consists of an experiment table equipped with a large multi-touch screen and a realistic learning device that can detect the user's simple gestures. In real world, some scientific experiments involve high cost, long time or dangerous objects, but this system will overcome such hindrance and provide learners with a variety of experiment experience in realistic ways.

서울시에 소재하고 있는 종묘와 사직단은 제례의식이 거행되던 곳으로 실제 재현은 1년에 약 한번 정도 진행되며 이것을 보기위해 관람객이 몰리게 된다. 이것은 일종의 병목현상처럼 일어나고 있다. 이러한 병목현상을 해소하고, 평소 관람객에게도 실제 재현과 같은 효과를 보여주기 위하여 실감형 콘텐츠를 활용하고자 한다. 마이크로소프트(MS)의 증강현실(AR)기기 '홀로렌즈(Hololens)' 기법을 바탕으로 관람자들에게 이용의 편의를 보완할 수 있는 방법을 제안한다.

This study is to examine the effects of gesture based interface and display methods to make an effective virtual learning environment. The gesture based interface can provide interactive interface to make objects in the virtual learning environment by generating natural movement of users' gesture. This natural functionality leads users to apply natural movements as they do in real actions. Because of the natural user interface, the gesture based interface is expected to maximize learning outcomes. This study examined how the gesture based interface can be used when a head mounted display is applied for a virtual reality learning environment. For this study 44 colleagues students were participated. Two display methods (head mounted display vs. monitor) and two interface (gesture based interface vs. joystick) were tested to identify which might be more effective. The study was applied to different learning tasks which require different levels of spatial perception. The dependent variables are three constructs of virtual presence (spatial perception, immersiveness, and realness) and task completion time and recall tests. This study discussed potential disadvantages of gesture based interface while it showed positive usages of gesture based interface.
