This study describes a new technique for human sensibility evaluation using electroencephalogram(EEG). Production of EEG is assumed to be linear. The linear predictor coefficients and the linear cepstral coefficients of EEG are used as the feature parameters of sensibility and pattern classification performances of them are compared. Using the better parameter, a human sensibility evaluation algorithm is designed. The obtained results are as follows. The linear predictor coefficients showed the better performance in pattern classification than the linear cepstral coefficients. Then, using the linear predictor coefficients as the feature parameter, a human sensibility evaluation algorithm is developed at the base of a multi-layer neural network. This algorithm showed 90% of accuracy in comfortableness evaluation in spite of fluctuations in statistics of EEG signal.

Simulators have been used to evaluate drivers'reactions to various transportation products. Most researches, however, have been concentrated on their technical performance, thus this paper considers drivers'senses of moving on a vehicle simulator through the analysis of human sensibility ergonomics. A sensibility ergonomic method is proposed in order to improve the faithfulness of vehicle simulators. A simulator of passenger vehicle consists of such three modules as vehicle dynamics, virtual environment, and motion representation modules. To evaluate drivers'feedback, human feelings are categorized into a set verbal expressions collected and investigated to find the most appropriate ones for translational and angular accelerations of the simulator The cutoff frequency of the washout alter ill the representation module is selected as one sensibility factor Sensibility experiments were carried out to find correlation between the expressions and the cut-off frequency of the filter. This study suggests a methodology to obtain an ergonomic database which can be applied to the sensibility evaluation of dynamic simulators.

This study describes a method of a human sensibility evaluation using photoplethysmogram(PPG) signal and a biofeedback algorithm to enhance the sensibility For this objective, the heart rate variability(HRV) is extracted from the PPG signal and using the HRV and its FFT the human sensibility is evaluated. The biofeedback algorithm is designed with motion image player interacting with the results of sensibility evaluation. The sensibility evaluation test showed feasibility of the designed method.

한국 기상청은 '생활산업 기상정보서비스'나 '위기탈출 안전날씨'와 같은 일상에 관련된 정보를 제공하고 있다. 한편, 해외에서는 독일의 '신체기상정보', 영국의 '건강 기상정보'와 같이 인간의 신체와 감성에 영향을 미치는 기상정보 역시 제공하고 있다. 비록 인간의 감성 변화가 심리학 연구 영역에서 다양하고 방대하게 이루어져 왔지만, 빅 데이터 분석 기반에 근거한 기상정보에 따른 인간의 감성 예측모형은 요원한 상태이다. 이 연구에서는 기상요소에 따른 인간의 감성변화를 예측할 수 있는 모형을 기상청의 기상 데이터셋과 SNS상 크롤링된 일자별 텍스트를 통해 개발하고 검증하고자 한다. 연구 결과 기상 요소들로 인간의 감성변화를 예측할 수 있는 모형을 만들고 검증할 수 있었으며 이는 기존 연구와 그 결을 같이한다고 볼 수 있다.

Maximizing profit is the most significant object of commercial places. Especially for some places where its atmosphere is main concern of customers like $Caf{\acute{e}}s$, interior design is crucial. Thus it needs to evaluate human emotion and preference. Human Sensibility Ergonomics which is recently signified in various fields is an attempt to quantitatively analyze factors of human sensibility and apply it to design operation. This study attempted to infuse human sensibility ergonomics into $Caf{\acute{e}}$ interior design and analyzed preferable $Caf{\acute{e}}$ interior design factors. Because most $Caf{\acute{e}}s$ have their own target customers, so we assumed four different target customer groups divided by their age and gender groups in each age group. As a result, the difference of each group could be examined. Middle-aged group and males have main interest in the intensity of luminance, i.e. the brightness, whereas youths and females attach importance to both quality of light and color. In addition, there is a tendency for middle-aged group and males to see $Caf{\acute{e}}$ as a public place while young people and females recognize $Caf{\acute{e}}$ as a place for entertainment. Taking the result of this study into consideration can lead to successful $Caf{\acute{e}}$ interior design for specific target customers.

Product design and development is very important process in enterprise activities. Reducing development time and reflecting consumer's needs is required to product design and development for increasing benefit and decreasing cost. Human sensibility ergonomics is one of the important technology of R&D in product development. However, the subjective method of human sensibility ergonomics has several problems to analyze and to Quantify experimental data and objective method of human sensibility ergonomics is still in process on study. In this research, new analyzing method is proposed for the subjective human sensibility ergonomics applied with fuzzy set theory. What is the useful theory for controlling uncertain type of information like human mind? This approach is more effective method for analyzing consumer's needs for product design and development process. At collecting needs, certainty scale is added for adapting hedge of fuzzy function. Using a kind of union operator, synthesize each item to analyze identification of each item with fuzzy hamming distance. Identification of analysis is classified with the relational weight using Relationship Chart Method, and is drawn the relationship diagram for clustering each item. A case study with sample test is conducted and demonstrated with this suggested method for more effective way.

The human sensibility caused by the motion of an object grasped by a human operator is defined as kinesthetic sense of arm. Due to nonlinearity and ambiguity of human sense, there is no absolute standard for quantification of kinesthetic sense. In this research, a so-called 2-dimensional arm motion generator is developed to present various mechanical impedance (i.e., stiffness or damping) characteristics to a human arm. The kinesthetic words representing arm kinesthetic sense are selected and then the subject's satisfaction levels on these words for given impedance values are measured and processed by the SD method and factor analysis. In addition, the quantification method using neural network is proposed to take into account the individual difference between the mean sensibility and each subject's sensibility. Through this proposed algorithm, the sensibility of human motion described qualitatively can be converted into engineering data ensuring objectivity, reproducibility, and universality.

Design that is emotionally gratifying is a product design that has been produced by considering user's emotions to give satisfaction through a compositive integration of environmental elements, user's psychological and cognitive element and products' physical elements. In the 21c, where this process of integration is much more appreciated, it could be predicted that the competitiveness of a product relies not on technological aspect but on how close the product to a human being as a communication aid. In the world these days, the changes of lifestyle has been excelled due to the rapid growth of scientific technology. It is needed more than ever for the designers to participate in Human Sensibility Ergonomics to cope with the changes and to design products that are emotionally correct. Therefore, Human Sensibility Ergonomics and design should work closely, organizing a system to sharing the research outcomes and investing opportunities for numerous researchers to study.

This paper describes the implementation process of Virtual Modeling system for a customer-oriented product. The human sense is measured and analyzed by physical design factors and can be applied also for the product design. The first step implementing virtual modeling is to make a human sensibility("Kansei") database. Human sensibility database is constructed with the relational data of Kansei words and design factors. The next step is extraction the design information from the human sensibility database by fuzzy inference algorithm. This design information is used for the input data for the graphic database. Virtual implementation software compounds 3D shape of product. The final product can be modified according to the customer's requirement.quirement.
