Success of brought a large revolution in the world of cinema and the media market. They have predicted new industrial possibility for 3D Stereoscopic image and trends started to support for producing in the field of various media platform. We can see our domestic technology creates higher added value in the sphere of hard-wear for the market of worldwide home TV electronics. But in reality we are short of effective and organized pipeline of producing and we should analyse cases more for Stereoscopic 3D animations. Therefore in this paper, we present case study on animation made into Stereoscopic 3D animation to build up suitable Stereoscopic 3D TV animations pipeline. We differentiate from any other Stereoscopic content by applying artistic elements and technological elements, especially human factor and 3D Sweetening to elevate the level of 3D Stereoscopic effect for main audience, children. We propose how to strengthen the competitiveness of Korean animation for world animation market.

Today, mobile technology is developing very fast and people use internet through mobile phones. Using mobile phones, people use games, email, avatar and other services. We designed client/server modules in order to join email and avatar together. First two major server modules were designed, one of them is DB management module for avatar user information and the other is email management module. One the client side, we designed avatar image animation module and a module for showing the email contents. The purpose of the design is to reduce the performance overhead on the client side as mobile phones cannot be used as a high performance device. We propose and implement a new avatar based service using the SK-VM environment, that is different from the current avatar services.

Creating controllable, responsive avatars is an important problem in computer games and virtual environments. Recently, large collections of motion capture data have been exploited for increased realism in avatar animation and control. Large motion sets have the advantage of accommodating a broad variety of natural human motion. However, when a motion set is large, the time required to identify an appropriate sequence of motions is the bottleneck for achieving interactive avatar control. In this paper, we present a novel method for training avatar behaviors from unlabelled motion data in order to animate and control avatars at minimal runtime cost. Based on machine learning technique, called Q-teaming, our training method allows the avatar to learn how to act in any given situation through trial-and-error interactions with a dynamic environment. We demonstrate the effectiveness of our approach through examples that include avatars interacting with each other and with the user.

최근 2D 애니메이션은 세계적으로 애니메이션 산업이 디지털화 되어가고 있고 디지털 기술의 발전은 끊임없이 애니메이션이 발전과 진화를 거듭되어 오면서 기존의 표준적인 제작파이프라인이 제작 환경과 기법에 따라 독특한 형태로 발전되어왔다. CrazyTalk Animator는 초보자, 교육관련 종사자, 비디오 편집자 및 완성도 높은 캐릭터를 생성하는 전문가와 같이 고성능의 애니메이션 툴을 필요로 하는 전분가 등의 최적의 애니메이션 솔루션을 제공하고 있다. 본 논문에서는 CrazyTalk Animator를 통한 애니메니션 제작 방법으로 아바타 기반의 배경과 소품을 드레그 & 드롭하여 세트를 만들고, 캐릭터들을 카메라와 타임라인 트렉으로 조정하고 제작하여 2D 애니메이션을 제작하였다.

A script language, which represents and controls avatar behaviors in a natural language style, is especially remarkable, because it can provide a fast and easy way to develop an animation scenario script. However, the studies that consider avatar behavior interactions with various virtual objects and intuitive interface techniques to design scenario script have been lack. Therefore, we proposed a context-based avatar-object behavior model and layered script language. The model defines context-based elements to solve ambiguity problems that occur in abstract behavior interface and it provides user interface to control avatar in the object-based approach. Also, the proposed avatar behavior script language consisted of a layered structure that represents domain user interface, motion sequence, and implement environment information at each level. Using the proposed methods, the user can conveniently and quickly design an avatar-object behavior scenario script.

James Cameron's Avatar was a stunning success for digital characters. Digital animation character creation was not suddenly enabled by visual technology, rather it was a result of numerous attempts of combining animation and live action film with the help of technology advancement. Two pioneers in this field are James Cameron and Robert Zemeckis. Although continuous interest and research in visual technology existed, the two directors differed in how they viewed the use of technology. The difference is demonstrated in their two recent movies which will be covered in details. How these two directors differed in their approach remains a topic of study for us who continuously are exposed on advance visual technology and our reaction to the changing nature of the industry.

This paper is implemented new styled site to combine community of blog style for SNS and shopping mall. Especially, this site is included simulation of coordination in fashion with avatar model. It makes indirect experience of clothing and user-friendly user interface that is different to other Web sites or shopping malls. So this avatar is designed and implemented by using flash animation technique that makes confirm possible coordination styles with eyes of client instantly and review goods very easily. Additionally, it makes pay attention to connect shopping malls and service convenience by SNS.

가상환경에서 애니메이션을 구현하는 방법으로는 여러 가지가 있다. 그러나 그 방법들을 살펴보면 애니메이션 데이터와 아바타 데이터가 서로 분리되지 못하고, 애니메이이션 데이터는 아바타 데이터에 종속되어 있다는 단점이 있다. 이에 본 연구에서는 애니메이션 데이터를 아바타 데이터에 독립적으로 기술할 수 있도록 새로운 행위 기술언어를 정의하고 이를 활용할 수 있도록 하는 시스템을 개발, 제시하도록 한다.

In this paper, we propose a new method which generates the trajectory of the mouth shape for the characters by the user inputs. It is based on the character at a basis syllable and can be suitable to the mouth shape generation. In this paper, we understand the principle of the Korean language creation and find the similarity for the form of the mouth shape and select it as a basic syllable. We also consider the articulation of this phoneme for it and create a new mouth shape trajectory and apply at face of an 3D avatar.

Having a virtual talking face along with a virtual body increases immersion in VR applications. As virtual reality (VR) techniques develop, various applications are increasing including multi-user social networking and education applications that involve talking avatars. Due to a lack of sensory information for full face and body motion capture in consumer-grade VR, most VR applications do not show a synced talking face and body. We propose a novel method, targeted for VR applications, for talking face synced with audio with an upper-body inverse kinematics. Our system presents a mirrored avatar of a user himself in single-user applications. We implement the mirroring in a single user environment and by visualizing a synced conversational partner in multi-user environment. We found that a realistic talking face avatar is more influential than an un-synced talking avatar or an invisible avatar.
