The article deals with the reality subject of animations. Animations are created on the basis of fantasy. Disney's introduction of the narratives and styles of live action film into the field of animation, which laid a foundation for the hyper-reality animation, has produced an unintended consequence of marginalizing other animation genres which have emphasized fantasy through free experimentations of various images. A combination of Disney's world view of hyper-reality with later-developed 3D computer animation technology has made fantastic figures and spaces much more real than the real ones, and succeeded in creating a matrix of simulacre, a world of mere copies without the original.

Nowadays, one-person media broadcasting has become popular, and with the progress of this popularity, multimedia techniques which can support such broadcasting are also becoming more and more advanced. One of the most emerging multimedia technique used in this field is the virtual reality technology which sets the one-person media broadcasting environment as a virtual reality environment. However, as such an environment requires instruments of high cost, it is not easy for normal individuals to constitute such environments. Therefore, in this paper we propose how to construct virtual reality-like panoramas with a multiple of smartphones. For this purpose, we designed a special rig which can hold firmly 8 smartphone cameras which have overlapping view of the environment such that panorama stitching becomes possible. To reduce the computation cost, we precomputed the homography matrices, and used 1-D pointer structures to store the computed coordinate values.

This paper proposes a mobile augmented reality mashup for cultural heritage sites such as natural monuments. Several benefits of mobile augmented reality solutions are ideal for preserving and protecting cultural heritage sites. By presenting mobile augmented reality mashup scenarios and mobile mashup framework, we introduce how user-generated multimedia contents can be added. We present two scenarios of Mashup Viewer and Mashup Maker. In Mashup Viewer mode, visitors can create new AR contents using mashup tools for memo, Twitter, images and statistical graphs. In Mashup Maker mode, other visitors also can view the user-generated multimedia AR contents using QR codes as access points. To show feasibility of our approach in mobile platforms, we compare several detection algorithms on PC and mobile platform and report on deployment of our approach in a natural monument museum. With our proposed mashup tools, visitors to the cultural heritage sites can enjoy default AR contents provided by the site administrators and also participate as active content producers and consumers.

Crosstalk has been regarded as one of inherent problems in a factor disturbing optimal viewing experiences. For this reason, display developers address the crosstalk issues. However, due to various display characteristics and viewing environments it is hard to estimate the crosstalk generated in real space. This paper proposes an interactive multi-view display simulator based on augmented reality for developing mobile autostereoscopic displays. This display simulator can be used for the developers to estimate the crosstalk and find optimal viewing zone intuitively. Typical parameters for mobile phone use are applied for the estimation. The proposed simulator provides visualized crosstalk in real space for them to determine better viewing zone interactively. The proposed system is expected to help establish ergonomic guidelines for mobile multi-view autostereoscopic display developers, designers, and viewers.

Despite of many supportive research to the usefulness of slide evaluation on environment of outdoor lighting, study method of using slides have provoked many discussions of its manifestation of reality of field conditions. This study aims to compare the results of slide survey with that of field survey. Distant view and short range view of nightscape of Seoul were selected. Field measurement of luminance and chromaticity were conducted and questionnaire survey were conducted. Frequency analysis, T-test, factor analysis were conducted. Results shows that distant view and short range view of field survey have better visual atmosphere than slide survey. In addition, slide survey on distant view shows lowest values. Difference between field survey and slide survey on distant view is much bigger than the results of short range view.

The government has defined domestic violence as one of the four major social evils and tried to prepare laws and systems to prevent it. Nevertheless, domestic violence has emerged as a serious social issue, and compare to the number of domestic violence cases that are constantly increasing, the report rate of domestic violence is significantly lower. This suggests the need to improve citizens' perception of domestic violence as the issue to solve it together in society, not as a private matter at home. Most of existing contents for preventing domestic violence and improving awareness are simple viewing forms of video contents, which have little effect on recognition. We aim to confirm the possibility of improving social awareness about domestic violence by producing Virtual Reality (VR) contents that have great features of user's immersion and empathy. In this VR content, the user can interact with various objects in the virtual reality of domestic violence and directly or indirectly experience the victim's position. Users who view the violent environment from the victim's point of view can have a subjective empathy for the problem, which is expected to induce more active awareness about domestic violence.

In Korea, the military has been conducting counseling forthe preemptive detection of psychologically unstable soldiers to prevent unexpected accidents and to help them adapt to military life. However, several soldiers feel anxious about face-to-face counseling with military officers and they have difficulty expressing themselves. Video See-Through HMD is a state-of-the-art mixed reality device that converts the user's real view into a digital view, which leads users to feel the actual situation as the virtual. To validate its usefulness as a new psychological counseling aid, we investigated 11 army soldiers who are under the counseling program in barracks. During the counseling conversation, participants were asked to wear or take off the Video See-Through HMD repeatedly. All conversations were recorded for behavioral observation. As a result, 80% of the soldiers showed a relatively stable state of mind when wearing the Video See-Through HMD, which leads them to be innocent and frank about their concerns. This method could improve the effectiveness of counseling to prevent unexpected accidents caused by unnoticeable psychological instabilities of the clients.

Parents' influence on children's development is generally considered essential. This paper attempts to explore the role of AR in preschool education from the perspective of parents, aiming to help parents better understand the impact of children's use of augmented reality in preschool education. The subjects were parents of children in the preschool age range (3-6 years old), and the experimental equipment was AR cognitive cards. In order to extract parents' views on AR, five parents were invited to conduct an experiment with their children using AR cognition cards, and then an open interview survey was conducted. In the second experiment, the answers obtained from the first experiment were sorted out and formed a questionnaire to conduct a closed-book survey. It shows that parents are satisfied with the characteristics of AR to assist their children's learning. At the same time, parents also value technology, usage management and playing environment. AR can stimulate children's learning initiative. Children like to use AR, AR is suitable for learning, make parents satisfied. But even if AR is suitable for learning, parents will control the time their children use it.

Due to the development of science and technology and the emergence of new industries, the environmental change of the digital contents industry is rapidly progressing. The scope of technological development in the digital contents industry is affecting not only the entertainment industry but also various industries. Recently, with the development of digital convergence using realistic content, games, video, and VR have provided new opportunities for the growth of the content industry. The researcher determined that a new education system would need to be changed as the digital contents industry developed. For this purpose, an AHP questionnaire was conducted for experts with a high basic understanding of the education platform based on previous studies. We proposed a platform model for human resource development as an education system that meets the demand of digital contents industry. The education system for nurturing talents needed by future society should include elements that can interest the learning of users. The platform should not be approached from a system point of view, but should be developed from the content and user's point of view, considering the platform's original purpose.
