This paper introduces a novel concept of 'A Green LED Sensitivity Lighting System' which can automatically estimate QoS(quality of service) and emotional requirements of user using smart phone. And it can intelligently control ambient illumination lamp to conserve electric energy and to satisfy human sensitivity. The proposed system has 4 control modes; emotional lighting, smart lighting, green lighting and realistic lighting modes in order to comfort man's emotion, to maximize work efficiency, to save energy consumption and to make the entertainment more fun, respectively. When we choose green lighting mode for indoor office situations, an elaborate simulation shows that the proposed system with home network can reduce the energy by 50% compared to conventional light control system with a fixed time-based switching.

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.

One of the main motivations of this research process is to develop an adaptable VR model whose color can be changed according to the emotional information of user. This paper addresses how to define color scheme and combine colors with harmony. The adaptable color of the VR model consists of three processes: emotional keyword identification, the color combination and the VR model adaptation processes. We have used the biorhythm to derive the emotional keyword which is used to find the color harmony scheme. The color harmony scheme provides information for the color combination of the VR model. Finally, we have obtained the VR model which color has been changed using the identified color schema.

Artificial environments and spaces developed in 20th century provided conveniences and comforts and developed spatial thoughts of interior design. But it caused significant environmental estrangement due to environmental disruption and materialism. This caused raising necessity of emotional design in human life spatial design as liberation of human nature is discussed and interest in emotion among human natures is being enhanced. This study manages how emotional design is expressed in basic area of human, residential area. Emotional design is proceeding to the direction designing interface between human and environment considering human physical and psychological characteristics focused on correlation between human and interior space. Therefore through this study, meanings and effects of design considering user emotions are reviewed to materialize expressing factors for combining into actual design.

본 연구에서는 질의를 기반으로 사용자의 감정상태를 예측하는 방법을 제안한다. 제안방법은 자극-감정 규칙베이스 구축, 규칙확률 값 기반 질의 랭킹, 질의 랭킹 기반 사용자 감정예측의 단계로 구성된다. 방법의 적절성을 검증하기 위하여 힘들다와 심심하다에 대한 결과로 사용자평가를 실시하였다. 힘들다의 결과에서는 힘들다 정도에 대한 점수가 높은 질의들을 지속적으로 검색하는 사용자들을 힘들다라고 판단할 수 있다고 분석되었다. 심심하다의 결과에서는 방법 간 유의미한 차이를 보이지 않았으나, 특정 개별질의의 지속적인 패턴을 분석하는 것이 좀 더 높은 점수를 얻은 것으로 평가되었다.

This study is the content of the environment-friendly is the tendency of one of postmodernism. Rather than end up post-modernism in the past, such trend has affected many in the design of modern furniture. Appeal to emotion in order to achieve an intimate relationship with the user, especially in the new material, you are the fulfillment of desire more than a simple function. In addition, designers of modern Many or even looking from the re-interpretation of the design past the motif of the design such as the time that post-modernism has arrived. Users who are using the furniture, because there is a tendency to features In addition to the primary that it has, you have to Want the meaning of one another, and to Serve by generating story distance from him this some. In this study, to target households that still is very important in modern design, and a historic of postmodernism the concept with a different meaning functional, the figurative to break free from meaning one-dimensional with the furniture I was analyzed on the basis of the flow.

After emerging online communications, text mining and sentiment analysis has been frequently applied into analyzing electronic word-of-mouth. This study aims to develop a domain-specific lexicon of sentiment analysis to predict box office success in Korea film market and validate the feasibility of the lexicon. Natural language processing, a machine learning algorithm, and a lexicon-based sentiment classification method are employed. To create a movie domain sentiment lexicon, 233,631 reviews of 147 movies with popularity ratings is collected by a XML crawling package in R program. We accomplished 81.69% accuracy in sentiment classification by the Korean sentiment dictionary including 706 negative words and 617 positive words. The result showed a stronger positive relationship with box office success and consumers' sentiment as well as a significant positive effect in the linear regression for the predicting model. In addition, it reveals emotion in the user-generated content can be a more accurate clue to predict business success.

Scent display is used mainly to augment immersion, reality and emotion, besides provide more tension and suggestion. However, this paper pay attention to effect of smells as ambient media, and propose a notification service using scents without sound and vibration when a user has new mail, test message and phone call. And we designed a scent service platform and API function for easy application of scent notification service. We demonstrated feasibility by experiment using smart phone and self-producted scent device.
