Among culture industry that greet digital generation and is observed 21th century the most representative game industry latest is caught what and more interest degree is rising. 2D and 3D animation accomplish continuous growth and development depending action expression along with development of computer technology, and 2D and 3D animation practical use extent are trend that is widening the area in TV, movie, GAME industry etc. through computer hardware and fast change of software technology. The trend of latest game graphic is trend that the weight is changing from 2D to 3D by 3D game and activation of 3D game character that raise player's immersion stuff and Control in 2D's simplicity manufacturing game balance for one side. This treatise that is reality of 3D game character to classify kind of (Motion Capture) and 3D character animation, form model the sense put. Recognize that is overview and reality of 3D game character first for this about example, and is considered to efficiency is high game industry and digital contents industry hereafter by proposing kind model classification of 3D game character animation, form model classification data and character animation manufacture process that application is possible at fast time and effect in 3D character animation application are big.

Classic cultivation theory and research has been noted for its failure to capture subtle variation in effects by genre and to consider tangible and practical dependent variables. Redressing these limitations, this study aimed at extending cultivation theory frame to incorporating fatalistic attitudes and reality television viewing, especially with the mediator of perceived realism. We first replicated the original cultivation effect by showing the significant effect of overall TV viewing. Even controlling for overall TV viewing, reality-based program use showed positive association with fatalistic beliefs; furthermore, the effect remained significant, additionally controlling for news(fact) use and drama(fiction) use. In a nutshell, the cultivation effect of reality-based TV program on fatalistic beliefs turns out quite stable even after controlling other competing genres.

The study considers the meaning of the composite images created when users capture present images over past images tagged location data in using the mobile augmented reality technology. The composite image through the location-based augmented reality technology is the result of matching the same location data between present images users are capturing and past images captured already. It is the new composite images that contain two different narratives-current and past in the same space and in real-time. We developed the mobile application implemented augmented reality technology and analysed the process that users create multi-layered narrative in the middle of capturing present image through augmented reality module. In addition, through the comparison with similar studies and applications of the augmented reality, we found that the key to give the multi-narrative in the composite images is the user's participation to put its personal intentions in real-time capturing process. In further development, we'll be able to utilize the application in order that users easily create multi-layered narrative composite image using cultural and personal records.

Recently, motion capture has become one of the most promising technologies in animation. Realistic motion data can be captured by recording the movement of a real actor with an optical or magnetic motion capture system. This paper deals with motion editing by a geometric mean filter. Since the captured motion has some noises that cause a jerky motion, it needs a smoothing process to make it natural. A geometric mean filter is proposed to produce natural motions without jerky motions. Experimental results show that the geometric mean filter can effectively remove noises that cause a jerky motion and it can guarantee the most natural motions among various spatial filters. This method could be applied to the various fields such as real time animation, virtual reality applications, 3D applications, and etc.

To improve the reality of motion simulator, the method of data-driven motion generation has been introduced to simply record and replay the motion of real vehicles. We can achieve high quality of reality from real samples, but it has no interactions between users and simulations. However, in character animation, user controllable motions are generated by the database made up of motion capture signals and appropriate control algorithms. In this study, as a tool for the interactive data-driven driving simulator, we proposed a new motion generation method. We sample the motion data from a real vehicle, transform the data into the appropriate data structure(motion block), and store a series of them into a database. While simulation, our system searches and synthesizes optimal motion blocks from database and generates motion stream reflecting current simulation conditions and parameterized user demands. We demonstrate the value of the proposed method through experiments with the integrated motion platform system.

본 논문은 영화, 방송, 애니메이션 등의 다양한 동영상 콘텐츠에 수화 애니메이션을 합성하여 동영상 콘텐츠를 청각 및 언어장애인들에게 이해시키기 위한 수화 통역 VR 콘텐츠 시스템을 제안하고자 한다. 제안된 시스템은 수화 사전에 있는 수화들을 3D 애니메이션으로 DB화하기 위해, 모션 캡처 시스템과 데이터 글러브를 사용하여 실제 사람처럼 자연스러운 애니메이션을 생성하였다. 최종적으로 동영상 콘텐츠의 자막이나 대본의 구문분석을 한 후, 이를 수화용 단어자막을 통해 수화 애니메이션을 DB에서 검색한 후, 실시간적으로 기존 동영상 콘텐츠와 동기합성을 하여 수화 통역 콘텐츠를 제공하는 VR 콘텐츠 시스템을 구현하였고 이 시스템을 동화용 애니메이션에 적용하였다.

This paper presents a novel approach to design evaluation of portable consumer electronic (PCE) products using augmented reality (AR) based tangible interaction and functional behavior simulation. In the approach, the realistic visualization is acquired by overlaying the rendered image of a PCE product on the real world environment in real-time using computer vision based augmented reality. For tangible user interaction in an AR environment, the user creates input events by touching specified regions of the product-type tangible object with the pointer-type tangible object. For functional behavior simulation, we adopt state transition methodology to capture the functional behavior of the product into a markup language-based information model, and build a finite state machine (FSM) to controls the transition between states of the product based on the information model. The FSM is combined with AR-based tangible objects whose operation in the AR environment facilitates the realistic visualization and functional simulation of the product, and thus realizes faster product design and development. Based on the proposed approach, a product design evaluation system has been developed and applied for the design evaluation of various PCE products with highly encouraging feedbacks from users.

Virtual reality (VR) technology has been increasingly more frequently used day by day in industries, entertainment and performances due to the development of AR and MR technologies. Performance arts also actively utilize $360^{\circ}$ VR technology due to the free expression of stage settings and auditoriums. However, technologies for systems in which performers wear VR devices firsthand rather than being in the sandpoint of bystanders while audiences wear VR head mounted displays(HMDs) to see performance stages have been rarely studied yet. This study investigated the technical possibilities of possible methods of expression that will enable performers to appear on the stage wearing VR devices. Since VR can maximize the sense of immersion with its closed HMD structure unlike augmented reality (AR), VR was judged to be suitable for studies centered on the mental interactions in the inner side of humans. Among them, to implement shamanistic expression methods with the phantoms of the body and soul, a motion capture technology linked with VR display devices and real-time cameras was realized on the stage. In this process, the importance of body ownership experienced by the performers (participants), reactions when they lost it, and the mental phenomena of the desire to possess the subjects of gaze could be seen. In addition, high possibility of development of this technology hereafter could be expected because this technology includes the technical openness that enables the audience to appear on the stage firsthand to become performers.
