The human sensibility product design requires information on consumer's emotions such as vision, auditory, olfactory, gustatory, or tactile perceptions. In this study, tactile sense which has not been well studied compared to other senses, is measured and statistically analysed. The emotional responses of 37 pairs of positive and negative adjectives describing tactile senses are collected and analysed through the questionnaire to find the correlation between adjectives and surface roughness of the sample. Mean ranks for 37 pairs of adjectives on four samples are obtained, and used to cluster these adjectives by factor analysis, multidimensional scaling, or cluster analysis.

This study developed a test with a high test-retest reliability consisting of 18 items by selecting from Korean adjectives describing tactile sensations. Principal components were extracted by three repeated measurements of 19 different fabrics for underwear. Adjectives such as 'smooth' 'soft' 'sexy' 'comfortable' and 'cozy' were most discriminating between preferred and non-preferred fabrics. The fabrics were analyzed by Kawabata Evaluation System in 16 mechanical properties, then these properties were analyzed by regression analyses as to their relations with human sensation and sensibility. Among the fabrics, the most preferred were made of polyester whereas the least preferred were made of gauze and cotton. Mechanical properties were identified that were related to the most discriminating adjectives such as 'smooth', 'soft', 'sexy,' and 'cozy'.

캥거루 케어의 특징을 반영하여 신생아의 감성에 긍정적인 영향을 미치는 스마트 감성 매트(SSM; Smart Sensibility Mat)를 개발, 제작하였다. 청감 자극의 경우 사전에 녹음된 어머니의 심장박동소리와 목소리를 30dB로 제공할 수 있는 블루투스 스피커를 매트에 삽입하였다. 촉감 자극의 경우 $32^{\circ}C$의 일정한 온도를 제공하기 위해 실리콘 소재의 온수 튜브를 매트의 표면에 삽입하고 자동온도조절장치와 연결하였다. 매트의 전체에 균일한 온도 제공을 위해 열전도성 실을 삽입한 직물을 매트 표면에 부착하였다. 면 패드로 매트를 감싼 후 피부 접촉과 비슷한 촉감 자극을 주기 위해 폴리우레탄 폼을 매트 표면에 접착하였다. SSM이 신생아의 감성에 미치는 효과를 보기 위해 생후 2주 이내의 건강한 신생아 10명을 대상으로 일반 매트(GM; General Mat) 및 SSM에 있을 때 생리신호인 심박수, 호흡수와 체온을 10분 간격으로 2회씩 측정하였다. 이를 3일에 걸쳐 1일 1회씩 측정한 후 대응표본 t검정을 실시하였다. 그 결과, GM에 있을 때 보다 SSM에 있을 때 심박수(t=8.131, p<.001)와 호흡수(t=7.227, p<.001)가 정상범위 안에서 유의적으로 감소하였다. 이는 SSM의 감각 자극이 신생아의 심리적 안정에 긍정적인 영향을 미쳐 GM보다 빠른 시간 내에 심리적 안정을 주는데 기여한 것으로 볼 수 있다.

Developed in this research is a TP (tangible prototyping) system, which consists of two modules; (1) a virtual reality model to evaluate the functions and appearance of the product, and (2) a haptic device to emulate tactile and kinesthetic properties of mechanical dial knobs. As an example, a washing machine is modeled using a commercial CAD system and transformed in VRML and X3D formats. Some dynamic behaviors and kinematic characteristics are programmed using X3D script and Java. Various haptic behaviors of the dial are generated by modulating torque profile according to the rotation angle. A torque profile measuring system is developed to evaluate the behaviors of the haptic dial physically. Haptic sensibility evaluations are accomplished using the TP by semantic differential method.

This study compares general jacquard fabrics and jacquard fabrics with optical fiber on mechanical properties, sensibility and preference evaluation of fabric for the blind. The analysis also assesses the effect of optical fiber in the evaluation and identifies those best suited for consumers. The mechanical properties of jacquard fabrics were measured by the KES-FB system. Sensibility and the preference of the jacquard fabric for the blind were rated on tactile sensation by women experts in their 20's and 30's. It was found that the optical fiber in jacquard fabric affected the change of mechanical properties as well as sensibility and preference. Jacquard fabric with optical fiber were softer and more transformable, while the fabrics had lower recover property by shear force and compression as well as more violent unevenness. Jacquard fabrics were also classified into three hand factors of surface property, resilience and weightiness. There were significant differences on surface property perceptions and weightiness, hand and blind preferences by optical fiber. Jacquard fabrics that contained optical fiber were not preferred by the blind because they were perceived to be uneven and heavy. Those, that were smooth and light, were preferred for jacquard fabric; in addition, fabrics preferred by the blind had good compression.

This research was designed to compare the subjective evaluation of texture image and preference by structure and sensible characteristics of women's suits fabrics between on- and off-line. 78 subjects who majored in fashion design evaluated the sensibility image and preference of 15 various kinds of specimens on- and off-line. Factor analysis, t-test, Pearson correlation and regression were used for a statistical analysis by SPSS WIN 13.0. The results of this study were as follows: 1. Women's suits fabrics were classified according to five sensibility image factors: 'classic', 'sophisticated', 'natural', 'characteristic', and 'practical'. 2. The results of the t-test showed that there were no differences between the on- and off-line evaluation of sensibility images. 3. The analysis of correlation indicated that the 'classic'-'sophisticated' and 'natural'- 'practical' sensibility images show a significant correlation between the two kinds of evaluation. 4. The results of regression revealed that 'sophisticated', 'characteristic' and 'practical' sensibility images had an effect on the purchase preference of women's suits fabrics. 5. 'Sophisticated', 'characteristic' and 'classic' sensibility images had an effect on the tactile preference of women's suits fabrics. 6. The structural characteristics of fabrics: thickness, weave and weight had an effect on the 'classic' sensibility image. Thickness had an effect on the 'sophisticated' sensibility image and fabric count had an effect on the 'characteristic' sensibility image.

본 연구는 소비자의 선호 촉감을 고려한 세면용 타월 개발에 도움을 주고자 수행되었다. 타월의 바탕조직은 동일하지만(면섬유), 파일을 구성하는 섬유의 종류가 서로 다른 3종(면 100%, 면 50% / 대나무 50%, 대나무 100%)을 시료로 선정하였다. 타월을 표준 세탁조건으로 반복세탁을 실시하였으며, 10회 세탁한 타월에 대하여 섬유유연제를 처리하여, 세탁에 따른 유연성과 흡수성(흡수속도와 흡수율) 등의 성능 변화를 고찰하고 대학생 남녀 소비자를 대상으로 주관적 감각과 촉감 선호도를 평가시켰다. 세탁횟수와 파일섬유의 종류에 따라 타월의 유연성은 유의한 차이를 보이지 않았다. 타월의 흡수성은 세탁에 따른 파일섬유의 종류에 따라 유의한 차이를 보여, 흡수속도는 대나무섬유 100%로 된 타월에서 높았으나, 흡수율은 면섬유로 된 타월이 높았다. 세탁 전 타월의 파일섬유 종류에 따른 주관적 감각 평가는 유의한 차이가 없었다. 세탁이 반복될수록 파일섬유의 종류에 따른 주관적 감각은 유의한 차이를 보였으며, 섬유유연제 처리시 더 부드럽고 매끄러우며 촉촉해진다고 평가하였다. 세탁 전 타월에 대한 촉감 선호도는 선호하는 편이었으나, 파일섬유종류에 따른 유의한 차이는 없었다. 세탁횟수가 증가함에 따라 타월에 대한 촉감 선호도는 다소 저하되었으며, 대나무섬유로 된 타월의 촉감을 가장 선호하였다. 타월의 촉감 선호도에는 평활감, 유연감 등의 주관적 감각과 섬유유연제 처리가 영향을 주었다.

Electro-chemo-mechanical devices or artificial muscles based on conducting polymers (CP) are presented as bilayers, CP/adhesive polymer, or as triple layers, CP/adhesive polymer/CP. Those soft and wet materials, working in aqueous solutions of a salt, mimic the composition of most organs from animals. Under electrochemical control, so working as new electrical machines, they produce continuous, reverse and elegant bending movements, mimicking those produce by animal muscles. By means of the current a perfect controls of the movement rate is attained giving soft and continuous movements. Muscles able to sense the chemical and mechanical conditions of work or muscle having tactile sense, as will be presented here, are being developed. All of them are founded on the non-stoichiometric nature of the soft and wet materials.

In order to help develop more comfortable seat cover fabrics, this study primarily surveyed the actual using conditions and the consumers' opinions of the seat cover fabrics. The results of this study were as follows: 1) The colors of seat cover fabric were mostly achromatic. Regarding comsumers' satisfaction on the colors of seat cover fabric, comsumers in their 20's were less satisfied than other age groups. Most unsatisfied consumers prefered bright colors. 2) On the materials of seat cover fabric, synthethic leather and woven were most widely used. Real leather was most prefered due to its luxury and tactile sensation. Woven was secondarily prefered due to its price and tactile sensation. About fourty percent of consumers covered the seat with other cover fabrics because of soil and other reasons. It will be useful if they could choose and change the seat cover fabircs with different materials and colors. 3) When consumers used the seat cover fabrics, the problems that they indicated were not durability and colorfastness but low breathablity during sweating, static electricity, soil, firmness, and cool sensation at the first contact.
