In this paper, by analyzing the nonverbal communication of personified animals and human animation characters, the differences of gesture and the amount of similarity between personified animal characters and human characters were studied. Accordingly, personified characters were classified into three categories: humanoid characters, animal-like characters and mixed-type characters which possess characteristics of both human and animals. Furthermore, we proposed a 7-step process for the personification of animal characters. Diverse information of personification was provided for animation designers in this paper. A DB system for animal character designing and automation for animation utilizing personified characters are expected to be constructed.

사이버 공간은 현실을 충실히 반영하지 않으며, 현실과 완전히 분리돼 있지도 않다. 하지만 사람들은 이 공간에서 자신의 행동과 생각이 증폭되고 확장되는 경험을 한다. 이뿐 아니라 상상만 했던 행동이 실제로 일어나기도 한다. 사이버 공간이 컴퓨터로 연결된기계의 공간이 아니라 인간의 심리적 공간이 되기 때문이다. 이는 사이버 공간에 있는 캐릭터가 인간의 심리를 대변, 인간에게 사이버의 매력에 빠지도록 유도하기 때문이다. 이에 연재를 통해‘디지털콘텐츠 매력, 캐릭터의 원형을 찾아서’라는 주제로 어떻게 매력적인 캐릭터가 탄생하고 변천했는가를 살펴보고자 한다.

The technique for synthesizing reactive motion in real-time is important in many applications such as computer games and virtual reality. This paper presents a dynamic motion control technique for creating reactive motions in a physically based character animation system. The leg to move in the next step is chosen using the direction of external disturbance forces and states of human figures and then is lifted though joint PD control. We decide the target position of the foot to balance the body without leg cross. Finally, control mechanism is used to generate reactive motion. The advantage of our method is that it is possible to generate reactive animations without example motions.

In this paper, we propose a automated techniques for generating the gait animation of humanoid character model required in game applications. The proposed method can generate motion data of various styles with intuitive manipulation, and techniques for editing motion data are also proposed. In addition, we introduce an automated tool for gait animation of character model developed with the proposed method to verify the effectiveness of our method. The proposed method tan be successfully employed in motion authoring tools. In this paper, only the gait animation was considered. However, the proposed method can be applied to various motions and can be utilized as a motion engine that automatically generates proper motion according to the state of the character. The motion engine can express various behavior of the character without requiring motion data base which is usually employed in 3D online games.

최근 많은 영화나 컴퓨터 애니메이션에는 인간형 3차원 캐릭터의 애니메이션이 등장하고 있다. 이러한 인체 애니메이션에는 인체의 움직임, 손가락이나 얼굴표정이 포함된다. 대부분의 경우에 자연스러운 인체의 움직임을 추적하기 위해 모션캡쳐를 이용하고 있지만, 이 경우 손가락이나 얼굴표정은 제외되므로 이에 대한 추가 작업이 필요하게 된다. 본 논문에서는 모션캡쳐 장비, 사이버글러브와 Face Tracker를 통합한 시스템을 소개하며, 이 시스템을 이용하여 실시간으로 캐릭터 애니메이션이 가능하게 한다.

본 연구에서는 ISO/IEC JTC1 SC24와 Web3D Consortium에 의해 제정된 국제표준인 H-Anim을 이용하여 캐릭터 애니메이션 교환을 위한 스키마를 정의한다. 기존의 H-Anim 에서는 인간형 캐릭터 구조의 전송이나 저장에 필요한 계층적 데이터 구조를 X3D 기반으로 정의하고 있으나, 생성된 애니메이션을 다른 캐릭터에 그대로 적용할 수 있도록 설계되어 있지는 않다. 본 연구에서는 임의의 H-Anim 캐릭터 모델에 임의의 모션 캡처 데이터를 이용하여 애니메이션을 생성할 수 있도록 H-Anim 에 애니메이션을 정의하는 방법과 이를 기존의 H-Anim 구조에 부합하도록 애니메이션 기능을 위한 스키마 확장에 대해 기술한다. 본 연구에서의 캐릭터 애니메이션 데이터 형식은 서로 다른 응용들 사이에서 애니메이션 데이터를 공유하고 서로 호환성을 갖도록 하는 것을 목적으로 한다.

In domestic game market, the video game market is getting smaller and also decreasing funds and high level developers. So we need the software that can help us to make more realistic and high quality contents by non-expert developer in poor environments. In this paper, we selected global studio's animations which were scored good evaluation by public and critics as a well-made emotional expression that can convey the emotion properly. We selected movements that express emotions from the animation scripts by using Ekman's 6 basic emotions and Greimas' dynamic predicate, and then we had analyzed and categorized with the data. We also analyzed the movements for which data we needed to create specific movements to express emotions by using 'Animation Layer' that used in Unity's blending process. And suggest concept of the program that to create the emotional expression movements by using those analyzed data.

Giant character used various SF movies and games in media convergence ages, and is essential for giant character in success contents. It This study defined giant character of SF movies and games, it analysed the eight of external characteristics and internal characteristics of giant character in SF movies and games. The external characteristics defined shape, silhouette, size and color, the internal characteristics defined fear, satanism, image and story focus, playfulness. Above, it was structured positioning model of giant character based eight characteristics and analyzation of example of SF movies and games. The elements of positioning model of giant characters are darkness, huge, abnormal, human, animal, fear, satanism, story focused, image focused and playfulness, and this study was proposed these model of elements of eight in SF movies and games.
