본 연구에서는 적외선 카메라 기반의 비접촉식 측정 방법을 이용하여 동공 반응 데이터를 수집하여 공감의 사회감성을 객관적이고 정량적으로 추정하는데 그 목적이 있다. 실험에는 10명(남 6명, 여 4명, M ± SD = 24.17 ± 2.16세)의 피험자가 참여하였다. 30초의 참조 데이터 측정 후, 공감 유무에 따라 과제는 얼굴 표정 모방 과제와 얼굴 표정 자발적 표현 과제로 구분되어 두 사람은 표정으로 상호작용하였고, 2번씩 반복 진행하며 적외선 카메라를 통해 동공을 촬영하였다. 이진화 및 원형 윤곽선 검출법의 영상처리를 활용하여 동공 데이터를 수집하였고, 이동 평균 기법을 활용해 눈깜빡임 노이즈를 제거하고 동공 크기 개인차로 데이터 표준화를 진행하였다. 공감 유무에 따른 동공 크기 데이터는 정규성 검증 및 독립표본 t검정을 통해 통계적 유의성을 확인하였다. 분석결과, 공감하는 경우(M ± SD = 0.508 ± 1.278)와 공감하지 않은 경우(M ± SD = 1.681 ± 0.968) 동공 크기가 통계적으로 유의미한 차이를 보였다(t(18) = -2.313, p = 0.033). 판별분석을 통해 동공 크기에 따른 공감의 유무를 추정하는 규칙을 정의하였다. 본 연구에서 제안한 동공 크기 데이터를 이용한 공감의 사회감성 추정 기술은 비접촉식 카메라 기반의 기술로 스마트 글래스와 접목되어 다양한 분야에 활용도가 높을 것으로 기대된다.

The precise measurement of human emotion is of pivotal importance in the field of emotion science. Based on the perspective of psychoneuroimmunoendocrinology, human emotion is now considered to be measurable by body fluid. The biological molecule cortisol, which is known for the stress hormone, has been widely investigated to help researchers to estimate the stress loaded on human body. Until now, several measurement techniques such as High Performance Liquid Chromatography (HPLC), fluorometric assay, and reverse phase chromatography have been developed. However, since these measurements are expensive, take relatively long time for an operation, and they are not portable, they are not appropriate for POCT (point of care testing). In this paper we demonstrate the performance of a miniaturized-microwave resonant device in the measurement of cortisol. Our method has many advantages in that it requires a small volume of sample, has fast response time, is easy to operate and needs no labeling process. Besides, it will shed a light on the measurement techniques for emotion science.

The technologies related to the development of cultural contents we known as cultural technology (CT). CT should evolve with the changes in the cultural contents market. Currently there are five major trends in cultural market change. First, consumers are seeking more and more sensible quality from products. Second, consumers are becoming less sensitive to the cognitive quality of products. Third, consumers demand more than what contemporary technology can offer. Fourth, as the cultural products market grows, the goal of content developments has shifted from producing a 'big hit product' to producing a product which will maintain market share. Fifth, cultural products are diversifying. All these trends make the cultural products developer's job more challenging. Sensation & emotional engineering (SE engineering) can be a useful tool for cultural products developers. SE engineering is a study of the somatic sensation and the aesthetic sensation for both fundamentals and applications aspects. By quantifying the physiological and psychological responses of consumers, it studies the physical nature of stimulants, providing basic knowledge for future applications and industrialization. One widely spread myth is that a sparkling idea from a talented individual will make a difference in the cultural products industry. The careful examinations of many successful cultural products prove this is not correct. Many successful cultural products are the result of a substantial amount of investment and employment of well polished marketing technology. A scientific approach is highly required for this matter and the SE engineering is an answer

In this modern era, human beings lead their life in complex environment where there are lots of parameters such as temperature, light, smell, sound, visual stimulus etc. that play important role for quality life. These parameters affect physical and mental behavior of a human being immensely. To ensure quality life the demand for quality products is always associated with human emotion and sensibility. Due to human sensibility and emotion involvement with quality life, the design stages of any kind of product must include some certain features related with emotion and sensibility. The cues for optimizing artificial environment are the physiological responses of human in that environment. The conventional approach of environmental physiology is to measure the relationship between environmental physical parameters and human psychological parameters under artificial conditions. Using that approach we tried to design an artificial environment for our daily lives and activities associated with both physiological and psychological behavior. We developed the technique to present the mock environment and software to measure and evaluate sensibility physiologically or psychologically and a simulator to measure and evaluate sensibility that can be utilized for large scale industrial production and design of environment. Simulator to measure and analyze human sensibility (SMAS) was constructed, which was utilized to estimate human sensibility and to simulate living and office environment.

제품이나 환경에 대한 인간의 반응은 생리적 변화로 나타나기도 하지만, 동작 반응(motor-response)으로 나타나기도 한다. 특히 제품으 감성적 설계를 위해서는 가장 기본적으로 이를 조작하는 인체의 자세와 동작에 대한 분석을 필요로 한다. 본 연구는 이를 위해 3차원 동작측정시스템과 힘판(forceplatform)에서 얻어진 원시 데이터로부터 인체의 자세와 동작을 평가하는 소프트웨어를 개발하는 것을 목표로 하였다. 개발된 소프트웨어는 누락 (mission)된 데이터의 보간(interpolation), 동작 애니메이션, 관절의 각도계산, 관절에서의 모멘트(momint)계산 기능등을 포함하고 있다. 본 논문은 진공청소기를 사용하는 동작을 기준으로, 이러한 S/W 개발 과정에 사용한 인체 모델과 각 관절의 모멘트 계산 방법에 대해 주로 기술 하였다. 3차원 동작측정시스템과 본 소프트웨어를 이용하면, 진공청소기, 냉장고 등의 제품을 사용할 때의 사용자의 작업 자세와 부하 평가가 가능해져 감성공학적 제품 개발에 활용할 수 있을 것이다.

차세대 하이테크 스마트 의류는 복합 차원에서의 감성적인 요소를 섬유 패션기술에 IT융합 기술을 이용하여 제공하고 있다. 생체신호를 이용한 감성은 모호하여 정량적이고 객관적인 측정이 어렵고, 그 표현도 제한된 감성 어휘에 의하여 나타나기 때문에 구체적으로 파악하는 것은 어려운 일이다. 이를 위하여 제품의 기능적 측면뿐만 아니라 정서적 감정과 선호도가 반영된 제품의 설계나 디자인 또한 요구되고 있다. 본 논문에서는 생체신호 측정을 위한 웨어러블 기반의 심전도 측정 의복을 제안하였다. 착용자가 평소 자주 입는 티셔츠를 응용하여 답답해하거나 불편하지 않게 제작하고 소매 형태로 신축성있는 소재를 사용한다. 인체의 형태에 따라 의복과 바이오센서의 전극이 안정적으로 밀착될 수 있도록 고탄력 밴드를 이용하여 일자형으로 제작하였다. 심전도 측정 의복을 착용에 의해 수집된 심전도 ECG 파형을 수집하고 심박변화율을 계산하는 시뮬레이션을 개발한다.

The door-lock switch is one of the most important part in the front-load washer. As an safety system, it keeps the door locked while the front-load washer or the dish washer is working and generating heat and spin. The door of front-load washer needs the emotionality as well as the safety because the consumers always get feels when using it. In this paper, We study about emotional factors in the door of front-load washer and analyze the difference of emotionality as the structure of the door-lock switch changed. For this, we analyze the force graph by using the software and the jig which can measure the force while the door is opened or closed.

Emotion recognition is defined as that machines automatically recognize human emotions. Because the human emotions is very subjective, it is impossible to measure objectively. Therefore, the goal of emotion recognition is to obtain a measure that is agreed by as many people as possible. Emotion recognition in a image is implemented as the method that matches human emotions to the various features of the image. In the paper, we propose an emotion recognition system using color features of clothing image based on the Kobayashi's image scale. The proposed system stores colors of image scale into a database. And extracted major colors from a input clothing image are compared with those in the database. The proposed system can obtain three emotions maximally. In order to evaluate the system performance 70 observers are tested. The test results shows that recognized emotions of the proposed system are very similar to the observers emotions.

In modern society, in business decisions of our customers are continually increasing in importance, and owing to the development of information and communication technology effectively on a computer to measure the preferences of key customer techniques are being studied. However, this preference reflects significantly on personal ideas, and therefore, it is difficult to commercialize a measure calculated according to the ambiguous results. In this paper, by using biometric information that has been measure; we have configured the multi-sensitivity models based on customer preferences to evaluate the proposed system. This system consists of multiple biometric information of multi-dimensional vector model for learning through the use of structured emotional to apply the same criteria to evaluate customer preferences. In addition, by studying the specific subject-specific emotion model, it is shown to improve accuracy with further experiments.
