This paper introduces an emotional behavior decision model for intelligent service robots. An emotional model should make different behavior decisions according to the purpose of the robots. We propose an emotional behavior decision model which can change the character of emotional model and make different behavior decisions although the situation and environment remain the same. We defined each emotional element such as reactive dynamics, internal dynamics, emotional dynamics, and behavior dynamics by state dynamic equations. The proposed system model is a linear system. If you want to add one external stimulus or behavior, you need to add just one dimensional vector to the matrix of external stimulus or behavior dynamics. The case of removing is same. The change of reactive dynamics, internal dynamics, emotional dynamics, and behavior dynamics also follows the same procedure. We implemented the proposed emotional behavior decision model and verified its performance.

Emotion is getting one of the important elements of the intelligent service robots. Emotional communication can make more comfortable relation between humans and robots. We developed emotional head robot system using 3D character. We designed emotional engine for making emotion of the robot. The results of face recognition and hand recognition is used for the input data of emotional engine. 3D character expresses nine emotions and speaks about own emotional status. The head robot has memory of a degree of attraction. It can be chaIU!ed by input data. We tested the head robot and conform its functions.

According to the researches of robot and software agent until now, computational emotion model is dependent on system, so it is hard task that emotion models is separated from existing systems and then recycled into new systems. Therefore, I introduce the Engine of computational Emotion model (shall hereafter appear as EE) to integrate with any robots or agents. This is the engine, ie a software for independent form from inputs and outputs, so the EE is Emotion Generation to control only generation and processing of emotions without both phases of Inputs(Perception) and Outputs(Expression). The EE can be interfaced with any inputs and outputs, and produce emotions from not only emotion itself but also personality and emotions of person. In addition, the EE can be existed in any robot or agent by a kind of software library, or be used as a separate system to communicate. In EE, emotions is the Primary Emotions, ie Joy, Surprise, Disgust, Fear, Sadness, and Anger. It is vector that consist of string and coefficient about emotion, and EE receives this vectors from input interface and then sends its to output interface. In EE, each emotions are connected to lists of emotional experiences, and the lists consisted of string and coefficient of each emotional experiences are used to generate and process emotional states. The emotional experiences are consisted of emotion vocabulary understanding various emotional experiences of human. This study EE is available to use to make interaction products to response the appropriate reaction of human emotions. The significance of the study is on development of a system to induce that person feel that product has your sympathy. Therefore, the EE can help give an efficient service of emotional sympathy to products of HRI, HCI area.

This paper presents the concept for the development of a pet-type robot with an emotion engine. The pet-type robot named KOBIE (KOala roBot with Intelligent Emotion) is able to interact with a person through touch. KOBIE is equipped with tactile sensors on the body for interaction with a person through recognition of his/her touching behaviors such as "Stroke","Tickle","Hit". We have covered KOBIE with synthetic fur fabric in order to can make him/her feel affection as well. KOBIE is able to also express an emotional status that varies according to the circumstances under which it is presented. The emotion engine of KOBIE's emotion expression system generates an emotional status in an emotion vector space which is associated with a predefined needs and mood models. In order to examine the feasibility of our emotion expression system, we verified a changing emotional status in our emotion vector space by a touching behavior. We specially examined the reaction of children who have interacted with three kind of pet-type robots: KOBIE, PARO, AIBO for roughly 10 minutes to investigate the children's preference for pet-type robots.

개인의 감성에 잘 부합하는 컨텐츠를 제공하기 위해선 개인의 취향과 컨텐츠를 이용할 때 어떤 감정을 가지고 있는지 알아야 한다. 개인의 취향을 알고 있다면 취향에 부합하는 컨텐츠를 재분류 할 수 있고 개인이 컨텐츠를 이용하려할 때의 감정 상태를 알 수 있다면 분류된 컨텐츠 중에서 감성에 부합하는 컨텐츠를 빠르게 제공할 수 있다. 본 논문은 개인의 취향을 인식하고 감정상태를 추측하여 연동된 플랫폼에 감정상태에 따른 결과를 출력하는 감성엔진을 제안 한다. 성격이 비슷한 사람은 비슷한 취향을 가지는 성향이 있으므로 취향인식을 위해 개인의 성격을 구별했고, 구별도구로 MBTI를 이용했다. 감정 추측을 위해 주변에서 일어나는 환경의 정보를 OCC 모델을 기반으로 분석하여 감정자극의 종류와 크기를 산출했다. 감정자극들을 감정그래프를 이용해 감정의 생성, 유지, 소멸을 관리하고 감정감정 상태에 맞는 결과를 출력했다.

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.

In this paper, we present a novel system to categorize web image search results using emotional concepts and to browse the results more conveniently and easily. The proposed system can categorize search results into 8 emotional categories based on emotion vector, which obtained by color and pattern features. Here, we use Kobayashi’s emotional categories: {romantic, natural, casual, elegant, chic, classic, dandy and modern}. With search results for a given query, the proposed system can provide categorized images for each emotional category. With 1,000 Yahoo! search images, we compared the proposed method with Yahoo! image search engine in respect of satisfaction, efficiency, convenience and relevance with a user study. Our experimental results show the effectiveness of the proposed method.

외부환경을 인식하고 상황을 판단해 자율적으로 행동하는 지능형 서비스 로봇은 앞으로 새로운 시장을 열어줄 것으로 기대되며 이와 관련된 연구와 개발이 빠르게 확대되고 있다. 이러한 서비스 로봇에게 가장 중요한 기능은 인간과의 원활한 상호작용이다. 여기서 말하는 상호작용이란 단순히 인간이 원하는 것을 명령하고, 로봇이 이 명령을 수행하는 것에 그치는 것이 아니라, 로봇이 스스로 인간의 감정을 파악하고, 이에 대한 적절한 로봇 자신의 감정 표출이나 서비스, 행동을 제공함으로써 직접적인 소통이 이루어지는 것을 의미한다. 이렇게 로봇이 자연스럽게 인간과 함께 공존하기 위해서 감성 로봇(Emotional Robot) 분야에서 관련된 연구가 활발히 진행되고 있다 본 논문에서는 국내의 감성 로봇의 연구 현황과 발전 방향에 대해 서술한다.

In this paper, we designed and developed an Emotional Speech Synthesis Markup Language (SSML) processor. Multi-speaker emotional speech synthesis technology that can express multiple voice colors and emotional expressions have been developed, and we designed Emotional SSML by extending SSML for multiple voice colors and emotional expressions. The Emotional SSML processor has a graphic user interface and consists of following four components. First, a multi-speaker emotional text editor that can easily mark specific voice colors and emotions on desired positions. Second, an Emotional SSML document generator that creates an Emotional SSML document automatically from the result of the multi-speaker emotional text editor. Third, an Emotional SSML parser that parses the Emotional SSML document. Last, a sequencer to control a multi-speaker and emotional Text-to-Speech (TTS) engine based on the result of the Emotional SSML parser. Based on SSML which is a programming language and platform independent open standard, the Emotional SSML processor can easily integrate with various speech synthesis engines and facilitates the development of multi-speaker emotional text-to-speech applications.

고해상도 HD 방송 및 3D 방송 시대를 맞아 좀 더 현실감 있는 방송에 대한 관심이 높아지고 있다. 이에 시청자의 오감을 자극하여 현장감을 높이는 기존 오감방송의 개념을 넘어서 감성방송 및 감성콘텐츠에 대한 관심이 높아지고 있다. 감성방송이나 감성콘텐츠는 콘텐츠 내의 물리적인 효과와 더불어 시청자가 콘텐츠의 내용으로부터 느끼는 각종 감정들을 정의하여 이를 적절한 감각효과로 변환하는 것에 초점을 맞춘다. 본 논문에서는 감성방송의 정의와, 감성방송이 갖추어야 할 선결조건 중 감성정보의 효과적인 추출방법, 감성 UX 엔진에 대한 간략한 개요를 설명한다.
