미디어 플랫폼의 다양화로 인하여 다양한 교육방법이 시도되고 있으며, 특히 교육용기능성게임은 G-learning 베이스로 새로운 교육방법으로 제시되고 있다. 하지만 "게임"이라는 부정적 인식으로 인하여 저변확대가 이루어지고 있지 않다. 게임을 즐기고 자라난 게임세대들에 대한 인식전환과 교육용 기능성게임에 대한 교육적 효과검증을 통하여 교육용 기능성게임을 새로운 교육방법으로 활용하기 위하여는 사회적 인식전환과 저변확대가 우선순위이다. 이를 위하여는 일반인들에게 교육용기능성게임을 알릴 수 있는 대회를 활성화하여 인식의 전환과 효과를 직접 체험할 수 있도록 해야한다. 이를 위하여 국내외 교육용 기능성게임대를 분석하고 활성화 방안을 모색하여 새로운 교육패러다임전환에 기여할 수 있는 방안을 제시하고자 한다. 이는 향후 국내 교육용 기능성게임 유저를 확산시켜줄 뿐만 아니라, 새로운 교육적 방법으로 활용할 수 있는 계기를 제시할 것으로 보인다.

In this study, the research model of VR·AR contents convergence education for solving social problems was presented after benchmarking the domestic and foreign realistic educational contents industry and policy trends and Fishbone diagram analysis. The goal was to create VR·AR content convergence talent for co-prosperity in the era of the fourth industrial revolution, and the target of education was students, researchers, and business personnel who are interested in VR AR technology education and contents business such as game animation, etc. The education model is based on understanding about storytelling of the socially disadvantaged, such as children and the elderly, and is technology education for content production including the application of virtual and augmented reality SW, and is a convergence education for content planning and business model strategy development.

In our life, stories are ubiquitous. Such stories of our lives are shared during counseling and psychotherapy. Modern storytelling is not limited to image and digital media. It encompasses various media, including offline contents such as festivals and theme parks. Furthermore, it is also utilized in film therapy. Film therapy refers to all the methods that utilize films and image media in counseling and psychotherapy. This paper summarizes and analyzes film therapy that utilizes storytelling. As the result of this analysis, it was found that we could gain insight into the identity of patients and their treatment through the storytelling that utilized films.

We present efficient algorithms for computing centroid directions for each of the three types of monotonicity in a polyhedron: strong, weak, and directional monotonicity, which can be used for optimizing directions in many 3D manufacturing processes. Strongly- and directionally-monotone directions are the poles of great circles separating a set of spherical polygons on the unit sphere, the centroids of which are shown to be obtained by applying the previous result for determining the maximum intersection of the set of their dual spherical polygons. Especially in this paper, we focus on developing an efficient method for approximating the weakly-monotone centroid, which is the pole of one of the great circles intersecting a set of spherical polygons on the unit sphere. The original problem is approximately reduced into computing the intersection of great bands for avoiding complicated computational complexity of non-convex objects on the unit sphere, which can be realized with practical linear-time operations.

Text has evolved along with the history of art as a means of communicating human intentions and emotions. In addition, text visualization artworks have been combined with the social form and contents of new media to produce social messages and related meanings. Recently, in text visualization artworks combined with digital media, communication forms with viewers are changing instantly and interactively, and viewers are actively participating in creating artworks by direct engagement. Interactive text visualization with additional viewer's interaction, generates external dynamics from text shapes and internal dynamics from embedded meanings of text. The purpose of this study is to propose a visual dynamics model to express the dynamics of text and to implement a text visualization system based on the model. It uses the deconstruction of the imaged text to create an interactive text visualization system that reacts to the gestures of the viewer in real time. Visual Transformation synchronized with the intentions of the viewer prevent the text from remaining in the interpretation of language symbols and extend the various meanings of the text. The visualized text in various forms shows visual dynamics that interpret the meaning according to the cultural background of the viewer.

In this paper, we propose a system and an intuitive interface that can create an athletic scene among athletes. We allow you to enter motion as if you were playing a game, so that the user's action becomes the player's action. The user can take various actions in front of the motion sensor and control the object flying to him. When a user specifies an opponent to pass or attack, and takes appropriate action in front of the motion sensor, the movement trajectory of the object is automatically generated by the physical optimization technique in accordance with the motion. In this way, you can create scenes where multiple players play together in a virtual environment. The method of this paper will be very useful for rapid prototyping for cinematic trailers of based on athletics games or animations.

최근 스마트폰의 보급으로 인해 디지털 기기에 지나치게 의존한 나머지 기억력과 계산 능력이 크게 떨어지는 디지털 치매가 사회적 이슈로 떠오르고 있다. 휴대폰은 점점 발전하여 스마트해지지만 사용자는 그와 반대로 디지털 치매 환자가 되어가는 것이 현실이다. 본 논문에서는 계산 능력을 향상시켜 디지털 치매를 예방하기 위해 간단한 사칙연산을 이용한 기능성 게임을 제시하려 한다. 기존 브레인게임에 없던 무작위 방식으로 남녀노소 모두 시간과 장소의 구애를 받지 않고 즐길 수 있어 디지털 치매 예방에 도움이 될 것으로 기대된다.

The recent expansion of the digital content market is increasing the technical demand for various facial image transformations within the virtual environment. The recent image translation technology enables changes between various domains. However, current image-to-image translation techniques do not provide stable performance through unsupervised learning, especially for shape learning in the face transition field. This is because the face is a highly sensitive feature, and the quality of the resulting image is significantly affected, especially if the transitions in the eyes, nose, and mouth are not effectively performed. We herein propose a new unsupervised method that can transform an in-wild face image into another face style through radical transformation. Specifically, the proposed method applies two face-specific feature loss functions for a generative adversarial network. The proposed technique shows that stable domain conversion to other domains is possible while maintaining the image characteristics in the eyes, nose, and mouth.

Trump cards are used in variable games in households such as poker and blackjack. In many cases, it is able to be helpful to algorithmically identify the playing cards from camera views. In this paper, we provide an approach that detects and identifies the playing card using template matching scheme, and evaluate the results of the provided implementation. For ideal cases, the implemented system provides a 100% success rate for card identification correct. However, non-ideal case of perspective distortion is estimated with 70% success ratio. This work aims to evaluate the effectiveness of augmented reality user interface for an entertainment application like playing card games.

요즘 다양한 스마트폰의 보급과 함께 스마트폰에서 활용되는 어플리케이션들이 주목 받고 있다. 그 중에 가장 활발히 어플리케이션이 개발되어 등록되어 있는 아이폰의 앱스토어는 개인 개발자들이 자발적으로 앱 개발에 참여할 수 있도록 유도하고 있다. 하지만 Xcode 라는 생소한 개발 툴을 이용하여 MacOS 라는 운영체제에서 개발을 하다 보니, 많은 기존 윈도우 기반의 스마트폰 개발자들이 아이폰 앱을 개발하는데 적지 않은 어려움이 있는 편이다. 본 논문에서는 아이폰에서 블루투스를 이용한 2 인용 대전 게임인 틱택토(Tick-tac-toe)를 C++기반으로 개발하여 그 내용을 소개한다.
