Recently, character agents are used as a user-friendly interface. In this paper, we have studied a generic framework for emotional character agents which are designed to infer emotions from diverse personalities, situations, user behaviors and to express them. The method of emotion inference is based on blackboard systems which are used to solve the problems in AI. Because it keeps independence between knowledge sources which are rules of emotions, a blackboard-based inference engine is easy to manage knowledge sources, Blackboard-based systems gave the system flexibility. So we can adapt the engine to various application systems. Each emotional agent monitors user behavior, learns user profile and infers user behavior. And it generates characters emotions according to the user profile. So, in case of same situations, the agent can generate different emotions according to users. We have studied to build an personalized emotional character agent which according to situations and user modeling.

This paper proposes Story Generation system based on Emotional Agent. In the proposed system, Emotional Agent is used as Actor whereas Story Generation produces goal and detailed plans to achieve goal. The storyline is constructed when the goal oriented plan is processed. The proposed system is effective and realistic since it employs human-like Emotional Agent as a main character in generating story.

It is difficult to let computer express feelings because of the ambiguity and nonlinearity. But it is said that expressing emotions is very important for high quality data processing and improvement of interactivity in WBI. In this paper, I surveyed emotion models from the view point of psychology. Next, I proposed WBI(Web Based Instruction) based on character agent considering emotional experience. By experimental result, the proposed model shows that has more user's preference than other existing WBI.

이동 통신 기술의 발달 및 대중화로 인하여 거의 모든 개인 사용자가 휴대폰을 사용하게 되었으며 휴대폰은 초기의 음성통화 기능 뿐만 아니라 VM(Virtual Machine)을 탑재하여 컴퓨터와 마찬가지로 프로그램을 작성 및 설치하여 사용할 수 있게 되었다. 본 논문은 휴대폰과 같은 특수한 임베디드 환경에서 감정 기반의 캐릭터 에이전트를 구현하기 위한 구조를 제안한다. 임베디드 기기의 특수성을 파악하고 주어진 제한사항을 극복하기 위해 기존의 단일 컴퓨터 상의 에이전트 아키텍처를 휴대폰과 서버의 역할을 분담하는 아키텍처로 변환하여 사용자로 하여금 컴퓨터와 근접한 수준의 캐릭터 에이전트를 이용할 수 있도록 한다.

Visual narrative or storytelling involve two important aspects of the cognitive perception: the conscious and subconscious. Color is one of the cognitive storytelling elements, its interpretation is captured by the subconscious and it is considered an emotional resource due to its psychological background. On the other hand, the character is also part of cognitive perception and storytelling tool, but this is interpreted consciously, character is considered as a logical resource. Ghibli and Disney have organized their cinematographic techniques in different ways, so it would be unfair to say that one narrative style is better than the other, it depends of perception of beauty which varies according to society. However the present study seeks to determine the differences between Ghibli and Disney narrative style, taking as reference color. Ghibli and Disney are perfect example about color effects as a storytelling agent, It can be classified in two aspects: dynamics of color and color as a narrative sequence. The dynamics of color analyzes how color acts and is perceived into a stage, its meaning and symbolism regardless of the character's actions. The narrative sequence studies how color thermologic evolves in scene's development.

In this research, we have developed a "computer tutor" that mimics the human tutor with animated tutoring dialog agent and the agent was integrated to teaching-learning material for elementary science subject. The developed system is a natural language based teaching-learning system using one-to-one dialogue. The developed pedagogical dialogue teaching-learning system analysis student's answer then provides appropriate answer or questions after comparing the student's answer with elementary school level achievement. When the agent gives either question or answer it uses the TTS(Text-to-Speech) function. Also the agent has an animated human tutor face for providing more human like feedback. The developed dialogue interface has been applied to 64 6th grade students. The test results show that the test group's average score is higher than the control group by 10.797. This shows that unlike conventional web courseware, our approach that "ask-answer" process and the animated character, which has human tutor's emotional expression, attracts students and helps to immerse to the courseware.

인터넷 기반 서비스업체들이 기하급수적으로 늘어나면서 업체들은 다른 업체들과는 차별화 시킬 수 있고, 사용자들에는 친근감을 제공하기 위해서 캐릭터 에이전트 연구를 진행 중에 있다. 그러나 현재 서비스되고 있는 캐릭터들은 사용자맞춤형이 아닌 단지 페이지기반으로 모든 사용자들에게 일괄적인 감정, 행동을 보여주고 있다. 이러한 방법은 항상, 누구에게나 같은 서비스를 해줌으로써 점차 사용자들의 신뢰성이 떨어질 수밖에 없다. 본 논문에서는 이러한 캐릭터 에이전트들의 신뢰성 증가를 위하여 사용자와 상호작용하면서 사용자의 성향을 파악하고 이를 학습하여 감정을 생성, 표현하는 Interactive, personalized, emotional 지능형 에이전트를 개발하고자 한다.
