The objective of this study was to compare and analyze the acceptability and consumption attitude for soy foods between Korean and Canadian university students as young consumers. This survey was carried out by questionnaire and the subjects were n=516 in Korea and n=502 in Canada. Opinions for soy foods in terms of general knowledge were that soy foods are healthy (86.5% in Korean and 53.4% in Canadian) or neutral (11.6% in Korean and 42.8% in Canadian), dairy foods can be substituted by soy foods (51.9% in Korean and 41.8% in Canadian), and soy foods are not only for vegetarians and milk allergy Patients but also for ordinary People (94.2% in Korean and 87.6% in Canadian). In main sources of information about soy foods, the rate by commercials on TV, radio or magazine was the highest (58.0%) for Korean students and the rate by family or friend was the highest(35.7%) for Canadian students. In consumption attitude, all of Korean students have purchased soy foods but only 55.4% of Canadian students have purchased soy foods, and soymilk was remarkably recognized and consumed then soy beverage and margarine in order. 76.4% of Korean students and 65.1% of Canadian students think soy foods are general and popular and can purchase easily, otherwise, in terms of price, soy foods were expensively recognized as 'more expensive than dairy foods' was 59.1% (Korean) and 54.7% (Canadian), and 'similar to dairy foods' was 36.8% (Korean) and 39.9% (Canadian). Major reasons for the rare consumption were 'I am not interested in soy foods' in Korean students (27.3%) and 'I prefer dairy foods to soy foods' in Canadian students (51.7%). However, consumption of soy foods in both countries are very positive and it will be increased.

We propose an emotional facial avatar that portrays the user's facial expressions with an emotional emphasis, while achieving visual and behavioral realism. This is achieved by unifying automatic analysis of facial expressions and animation of realistic 3D faces with details such as facial hair and hairstyles. To augment facial appearance according to the user's emotions, we use emotional templates representing typical emotions in an artistic way, which can be easily combined with the skin texture of the 3D face at runtime. Hence, our interface gives the user vision-based control over facial animation of the emotional avatar, easily changing its moods.

최근 WWW(World Wide Web)이 확산되면서, 정보들을 좀 더 자유롭게, 시간과 공간의 제약을 받지 않으면서 이용할 수 있게 되었다. 하지만, 초기 Web 기반 기술은 2차원적이고, 수동적인 정보를 제공하는 정도였다. 이에 비해 사용자들은 좀 더 실제의 세계와 유사한 3차원 환경에서, 능동적으로 참여하기를 원했고 이런 사용자들의 욕구에 발 맞춰 많은 기술들이 쏟아져 나오기 시작했다. 본 논문에서는 최신의 VRML과 JAVA기술들을 활용하여 Web 상에서 3차원 실시간 방송 시스템을 구현하였다 클라이언트가 직접 방송에 참여하거나 관람만 할 수 있는 모드를 제공하고 있으며, 실제 방송 참여자들은 자신의 아바타(avatar)를 선택하여 행동 콘트롤러와 자동 행동 발생시스템을 통해 좀 더 동적인 동작과 함께 방송에 참여할 수 있도록 하였으며, 일반 관람인의 경우 웹상에서 실시간으로 방송이 진행되는 모습을 볼 수 있다.

The purpose of the present study was to examine the effect of 3D avatar-based Virtual Reality chatting on college students' English learning achievement. Forty college sophomore students participated at this study and the research lesson continued for 8 weeks. They were administered to take a pretest to evaluate their vocabulary knowledge and writing skills. Their progress was assessed on the basis of midterm. Finally, a post-questionnaire was administered to measure their interest and understanding toward their learning experience in 3D avatar-based Virtual chatting. The results of this study indicated that there was a statistically significant difference between the control group and experimental group with respect to their midterm scores and writing. The result of the post-survey indicated the interest of English was statistically higher than the understanding of English.

영화 '아바타'를 계기로 다양한 입체영화의 등장과 3D TV의 대중화로 인해 입체영화를 비롯한 입체 콘텐츠에 대한 관심이 증가되고 있다. 또한 MS사의 '키넥트'가 인기를 끌면서 사용자와 영상 콘텐츠 간의 상호작용 기술이 게임을 중심으로 다양한 분야에 적용되고 있다. 본고에서는 입체영상을 제작하는데 있어서 필요한 촬영 기술 및 관련 장비의 현황 및 스테레오 입체영상의 색감일치 기술의 현황을 소개하고자 한다. 아울러 영상 콘텐츠와 사용자 간의 상호작용을 위한 비전 기반의 상호작용 기술 및 장비의 현황에 대해서도 살펴본다.

The sign-language can be used as an auxiliary communication means between avatars of different languages in cyberspace. At that time, an intelligent communication method can also be utilized to achieve real-time communication, where intelligently coded data (joint angles for arm gestures and action units for facial emotions) are transmitted instead of real pictures. In this paper, a method of generating the facial gesture CG animation on different avatar models is provided. At first, to edit emotional expressions efficiently, a comic-style facial model having only eyebrows, eyes, nose, and mouth is employed. Then generation of facial emotion animation with the parameters is also investigated. Experimental results show a possibility that the method could be used for the intelligent avatar communications between Korean and Japanese.

We propose a human-robot interaction(HRI) platform based on motion capture and mapping. Platform consists of capture, processing/mapping, and action parts. A motion capture sensor, computer, and avatar and/or physical robots are selected as capture, processing/mapping, and action part(s), respectively. Case studies-an interactive presentation and LEGO robot car are presented to show the design and implementation process of Kinect based HRI platform.

본 논문은 기존의 수화 발생 시스템이 갖는 처리 성능의 한계와 신체요소의 움직임에 대한 문제점을 지적하고, 이를 개선하기 위해 하이퍼 수화문장을 제안한다. 하이퍼 수화문장은 기존 수화문장의 구조를 확장하여 수화단어와 신체효소의 동작기호로 구성된 수화문장이다. 제안한 하이퍼 수화문장 생성 방법에 따라 하이퍼 수화어절을 연결하여 수화동작을 합성하고 수화문장에 대한 아바타의 움직임을 실제 수화자와 유사하게 생성하는 시스템을 보인다.

본 논문은 거울 투영을 이용하여 2D의 감정인식 데이터베이스를 3D에 적용 가능하다는 것을 증명한다. 또한, 감정 확률을 이용하여 퍼지 모델링을 기반으로한 얼굴표정을 생성하고, 표정을 움직이는 3가지 기본 움직임에 대한 퍼지이론을 적용하여 얼굴표현함수를 제안한다. 제안된 방법은 거울 투영을 통한 다중 이미지를 이용하여 2D에서 사용되는 감정인식에 대한 특징벡터를 3D에 적용한다. 이로 인해, 2D의 모델링 대상이 되는 실제 모델의 기본감정에 대한 비선형적인 얼굴표정을 퍼지를 기반으로 모델링한다. 그리고 얼굴표정을 표현하는데 기본 감정 6가지인 행복, 슬픔, 혐오, 화남, 놀람, 무서움으로 표현되며 기본 감정의 확률에 대해서 각 감정의 평균값을 사용하고, 6가지 감정 확률을 이용하여 동적 얼굴표정을 생성한다. 제안된 방법을 3D 인간형 아바타에 적용하여 실제 모델의 표정 벡터와 비교 분석한다.

The purpose of this study is to provide a basis for creating virtual community based on Cyber house. Cyber house is a digital architecture which enables multifarious lives based on the self, neighbor, new information. This study presents a process of Cyber house model and suggests scenarios of Cyber house application. Cyber house model has been developed by using SCOL but there were a few problems to design Cyber house. Since Java3D has flexibility to create Cyber house without limitation, even though it is very difficult to develope, it may well suited to make Cyber house. .Therefore Cyber house has to be developed as an instrument which provides various function rather than simple 3 dimensional digital house. Cyber house has a lot of potential and contribute to the Quality of lives.
