본 연구에서는 슈트용 직물의 촉각 자극 시 나타나는 감성 특성을 파악하고, 이를 바탕으로 직물의 스치는 소리가 공감각적 감성변화에 어떠한 영향을 미치는지를 분석하기 위해 물리적 평가 및 주관적 평가를 실시하였다. 피험자 20명을 대상으로 직물의 촉감을 평가하게 한 후, 그 직물의 스치는 소리를 제시하여 감각과 감성을 평가하도록 하였다. 복합자극으로는 직물별 tm치는 소리와 촉감을 동시에 제시하여 때 감성을 평가하였다. 실험결과 촉감에 대한 감성차원으로는 '심미성'과 '개성'의 두 가지 요인이 나타났고, 소리에 대한 감성차원으로는 '심미성'과 '고급감', '개성'의 세 가지 요인이 도출되었다. 심미성을 유발하는 촉각성 요인으로는 'pliable'과 'cool', 개성을 유발하는 촉감성 요인으로 'smooth'와 'cool'로 나타났다. 청각자극에 의한 감성은 'loudness'가 가장 큰 영향을 미쳤다. 촉감자극에 의한 직물 별 소리 자극을 부가하였을 경우 직물 소리의 물리량에 따라 심미성 요인에서 감성의 상승 및 하강 효과를 발견할 수 있었다.

There are few that evaluate tactile emotion as it pertains to car interior parts, while studies on visual evaluations of car interiors as well as usability tests in a visual sense are numerous. The purpose of this study is to determine typical in-vehicle tactile emotions so that they can be used to evaluate tactile impressions of car interior parts. 52 words related to tactile impressions of car interiors were gathered from a survey in conjunction with an in-vehicle test, interviews with the car salespersons, and an analysis of car reviews. After a factor analysis with 52 words, 10 categories of major tactile emotions were clustered. These were roughness, toughness, friction, comfortability, stiffness, softness, temperature, sleekness, familiarity, and flexibility. These representative tactile emotions regarding a car interior can be used to evaluate tactile impressions of surfaces such as leather, plastic, metal and wood when used as parts in car interiors.

This study aims to develop luxuriousness models based on both users' subjective feelings and objective material characteristics of automobile crash pad using Kansei engineering approach. Based on the results of literature survey and FGI, 12 Kansei variables describing look-and-feel and touch feel and crash pad design variables were extracted for systematically developing both a conceptual model of luxuriousness and a questionnaire for Kansei evaluation. A total of 41 various crash pad samples and 60 participants(customers: 30, designers: 30) were employed to evaluate the crash pad samples using the questionnaire with 9-point semantic differential scale and 100-point modified magnitude estimate scale. Based on the survey results, luxuriousness models were developed by using regression and quantification I method. In addition, they were compared and contrasted with respect to the relative importance of Kansei variables. Consequently, the developed luxurious model could suggest the preferred combination of material properties of crash pad.

This study aims to compare and contrast the Kansei modeling methods for building a luxuriousness model that people feel about appearance of mobile phones. For the evaluation based on Kansei engineering approaches, 15 participants were employed to evaluate 18 mobile phones using a questionnaire. The results of evaluation were analyzed to build luxuriousness models through quantification I method, neural network, and decision tree method, respectively. The performance of Kansei modeling methods was compared and contrasted in terms of accuracy and predictability. The result of comparison of modeling methods indicated that model accuracy and predictability was closely related to the number of variables and data size. It was also revealed that quantification I method was the best in terms of model accuracy while decision tree method was the best modeling method with small variance in terms of predictability. However, it was empirically found that quantification I method showed extremely unstable predictability with small number of data. Consequently, it is expected that the research findings of this study might be utilized as a guideline for selecting proper Kansei modeling method.

In this paper, a sound quality indices for the evaluation of vehicle intake and exhaust noise were developed through a correlation analysis of objective measurement data and subjective evaluation data. At first, intake and exhaust orifice noise were measured at the wide-open throttle sweep condition. And then, acoustic transfer function between intake orifice noise and interior noise at the steady state condition was measured. Also, acoustic transfer function for exhaust system was measured as the same method. Simultaneously, subjective evaluation was carried out by the paired comparison and semantic differential method by 27 engineers. Next, the correlation analysis between the psycho-acoustic parameters derived from the measured data and the subjective evaluation was performed. The most critical factor was determined and the corresponding sound quality index for the intake and exhaust noise was obtained from the multiple factor regression method. At last, the effectiveness of the proposed index was investigated.

Affective aspects of design attributes such as color, Pattern, and texture are important to the overall impression and the success of interior products. Among all the interior materials, wallpapers and flooring materials take up largest construction area and they are main components in creating affective impression for customers. This study aims to investigate the relationship between luxuriousness and related affective variables and design elements of wallpapers and flooring materials. The approach consists of 3 steps: (1) selecting related affective features and product design attributes through a literature survey, opinion of expert panel, and focus group interview, (2) conducting evaluation experiments, and (3) developing Kansei models using multivariate statistical analysis and analyzing critical attributes. Evaluation experiment was conducted using a questionnaire made up of 7-point scale and 100-point scale and 30 housewives and 20 interior designers participated in the evaluation experiment. The result of evaluation was analyzed through principal component regression and quantification I analysis. As a result of analyzing the survey data, the relationship between luxuriousness and related affective features and product design attributes was identified, moreover a optimal combination of the design component was identified. Consequently, it is expected that the results of the study would be a basis of the concept of emotion-based design by giving insights about how customers perceive the luxuriousness and suggesting the optimal combination, and providing specific quantitative design guidelines.

Sounds of electrically powered vehicle components such as window lift system, roller blind, etc., are required to be more comfortable and not to irritate the people emotionally. In this paper, a study was conducted to identify the significant sound quality metric and compose the luxuriousness sound quality index of electrically powered vehicle roller blind which is part of vehicle sunroof system. Before conducting subjective evaluation, sound characteristics of roller blind was analyzed and set the target operating sound for subjective evaluation. Thus, transfer sound of roller blind which has the characteristics of sound modulation was used for subjective evaluation. Multiple linear regression analysis was carried out by chosen Zwicker's metrics which are pointed by comments of jurors. Loudness and sharpness related metrics are prime metrics in luxuriousness sound quality index we composed. Also, effect of roller blind assay when it is attached to real vehicle was identified to evaluate the validity of index.

개인적 삶의 질 향상과 함께 사회적인 삶의 가치를 추구하여 인체친화적이며 동시에 환경 친화적인 제품 소비에 가치를 두는 LOHAS 트렌드의 영향으로 의류 제품에서는 소비자의 요구 수준에 맞춘 고급화, 고기능화된 의류 상품 및 소재 중심의 소비와 함께 친환경 소재, 리사이클 소재 등에 대한 관심이 증가하고 있다. 최근 Ramie 복합 소재는 이러한 트렌드에 적합한 대표적인 소재로서 고감성/웰빙 신섬유 제품 개발을 통해 신시장 개척이 가능한 아이템으로 주목받고 있다. 한편, Ramie는 땀에 대한 흡습성과 속건성이 우수하고 청량감이 있어 주로 여름 소재로 활용되어 왔으나 촉감이 좋지 못하고 광택성이 떨어지는 단점이 있어 이를 보완하기 위해 촉감이 좋고 광택성이 뛰어난 레이온 계열의 소재와 혼방하여 고급스럽고 환경 친화적인 의류소재로써 개발이 진행되고 있다. 본 연구에서는 이러한 레이온계 섬유 중에서 상품성이 modal 섬유 Tencel 섬유를 각각 혼방한 Ramie/Modal(28's,30's), Ramie/Tencel(28's) 복합소재의 반응성 염료에 대한 염색특성을 비교 고찰해 보았다. 실험은 Heterobifunctional type 반응성 염료 3종(Red, Yellow, Blue)을 이용하여 흡진 거동, 빌드업 특성, 겉보기 색상농도 등을 비교하였으며 1/1 standard 농도에서의 제반 견뢰도를 비교 평가하였다.
