본 연구에서는 승용차에서 사람들이 기기를 사용하기 위해 사용하는 기동어인 "Hi, KIA!"의 감성을 기계학습을 기반으로 분류가 가능한가에 대해 탐색하였다. 감성 분류를 위해 신남, 화남, 절망, 보통 총 4가지 감정별로 3가지 시나리오를 작성하여, 자동차 운전 상황에서 발생할 수 있는 12가지의 사용자 감정 시나리오를 제작하였다. 시각화 자료를 기반으로 총 9명의 대학생을 대상으로 녹음을 진행하였다. 수집된 녹음 파일의 전체 문장에서 기동어 부분만 별도로 추출하는 과정을 거쳐, 전체 문장 파일, 기동어 파일 총 두 개의 데이터 세트로 정리되었다. 음성 분석에서는 음향 특성을 추출하고 추출된 데이터를 svmRadial 방법을 이용하여 기계 학습 기반의 알고리즘을 제작해, 제작된 알고리즘의 감정 예측 정확성 및 가능성을 파악하였다. 9명의 참여자와 4개의 감정 카테고리를 통틀어 기동어의 정확성(60.19%: 22~81%)과 전체 문장의 정확성(41.51%)을 비교했다. 또한, 참여자 개별로 정확도와 민감도를 확인하였을 때, 성능을 보임을 확인하였으며, 각 사용자 별 기계 학습을 위해 선정된 피쳐들이 유사함을 확인하였다. 본 연구는 기동어만으로도 사용자의 감정 추출과 보이스 인터페이스 개발 시 기동어 감정 파악 기술이 잠재적으로 적용 가능한데 대한 실험적 증거를 제공할 수 있을 것으로 기대한다.

With the ingenious properties of unconstrained formativeness and frank expression of materiality the exposed concrete became popular with numerous architectures. The application of the exposed concrete has expanded to indoor environments such as commercial and residential spaces beyond the building exteriors with the uncompromising nature of its materiality. The purpose of this study is to conduct sensibility evaluation of the exposed concrete finish in interior spaces. The sensibility evaluation is conducted through a survey on a set of space models of the exposed concrete finish. The three rendered space models were evaluated by emotional vocabulary of 18 pairs of words. The result were as follows: First, the emotions derived from the exposed concrete finish are 'modern', 'cold', 'simple', 'restrained', 'rough', 'dark', 'new', 'chic', 'familiar' and 'eco-friendly'. Second, three sets of space models with alternative materials on walls and floors in exposed concrete interior space showed clear difference in sensibility. A space with the exposed concrete finish on the floor, the walls and the ceiling showed the results of 'cold', 'dark', 'rational' and 'masculine'. In the exposed concrete finish environment with wood flooring 'comfortable', 'warm', 'bright' senses and with white paint finish on the wall 'bright', 'practical', 'ordinary' and 'restrained' senses were obtained. Third, all three images achieved senses of 'chic', 'modern', 'new', 'pleasant', 'environment friendly' and 'satisfactory'. The modernity and stylish expressions of the exposed concrete finish were kept with the application of different material finishes as well as complementing its cold and rough expressions with warmth and brightness.

Because hand-written characters, especially drawn by a brush can give readers various impressions, they are not only a communication method but also art works. Authors have already investigated the relationship between brush motion analytical results and sensory testing results obtained from Japanese hiragana and reported quantitative evaluation method for the beauty of hiragana, In this paper, sensory tests for South Koreans who cannot recognize the word are carried out, compared with sensory testing results of Japanese. The evaluation objects are 6 hiragana drawn by 4 beginners and 2 experts, Semantic Differential Method based on 30 paired evaluation words are used in the sensory tests. Therefore South Koreans also feel the beauty in hiragana drawn by experts, as compared with by beginners. On the other hand it was confirmed that South Koreans couldnt recognize the difference among beginners. Judging from the factor analysis results, both Japanese and South Koreans selected stability as the 1st factor, there is interesting difference in the following orders.

초연결사회의 시대가 도래하여 시간과 공간의 제약없이 효율적으로 정보를 전달할 수 있는 스마트 디바이스의 사용이 보편화되었다. 스마트 디바이스는 사람과 사물 간의 상호작용을 통하여 정보를 전달할 수 있도록 점차 웨어러블 형태로 발전하고 있으며, 의복 형태의 스마트 디바이스인 스마트의류는 인체에 가장 밀착한 상태로 각종 생체신호 등의 측정이 가능하기 때문에 미래 일상생활에서 사용도가 높아질 것으로 주목받고 있다. 기존에 개발된 스마트의류는 의복에 전자장치를 부착한 형태로 개발되어 기기 이물감으로 인해 착용 시 사용자의 불편을 야기하여 지속적으로 생체신호를 측정하기에 한계가 있었다. 이에 따라 점차 전자장치가 텍스타일 내의 한 요소로 통합되어 있는 스마트 텍스타일을 기반으로 한 스마트의류의 개발이 요구된다. 본 연구에서는 현재 소비자에게 가장 근접한 웨어러블 디바이스인 스마트워치 사용자를 대상으로 하여 사용경험에 기반한 감성을 통해 웨어러블 디바이스에서 사용자가 필요로 하는 요구조건을 탐색하고자 하였다. 스마트워치 사용자의 경험에 기반한 감성에 대해 구체적인 답변을 얻고자 반구조화 된 심층인터뷰를 통해 질적 연구를 수행하였으며, 심층인터뷰 내용을 바탕으로 사용자감성을 기능적, 심미적, 사회적, 경험적 네 가지 측면으로 분류하였다. 측면별로 감성키워드를 설정하여 빈도 수 확인을 통해 스마트워치 사용자의 관심도를 알아보았다. 본 연구의 결과를 미래의 웨어러블 디바이스로 주목받고 있는 스마트의류 제작에 필요한 스마트 텍스타일 개발을 위한 기초자료로 활용하고자 한다.

Color selection plays a vitally important role in creating impressions of individuals or companies. This is largely because colors have sensibility aspects, which relate, in part, to images and, in part, to associations. Based on theories of color harmony and sensibility ergonomics, we have developed quantitative and systematic metrics for color images. In this paper, we suggest a color coordinate system that supports color analysis and color harmony functions using color images, which can be captured by corresponding adjectival words. We focus on a prototype system for graphical logo design to exemplify our concepts. The system can be applied to a wide variety of design domains.

Form-ratio means the ratio of Height/Width/Depth in 3-dimensions. The golden ratio or golden section is included as one of the form-ratio. Kansei Engineering System has some basic design databases. Form-ratio and color are basic design elements and they are very important for designing various products in viewpoint of Kansei Engineering. The subjects evaluate the form-ratios of 3-dimensional cubes and virtual products (refrigerator) with SD-scale kansei words(feelings and images). The golden ration was evaluated as "not beautiful" in refrigerator. We compared with the kansei of cube model and virtual product, and obtained databases of the relationship between the form-ratio and kansei.

Form-ratio means the ratio of height/Width/Depth in 3-dimensions. The golden ratio or golden section is included as one of the form-ratio. We conducted two kinds of kansei experiments of cubic model and refrigerator varied from 1:1:1 to 1:1:3.66 on the scale of x:y:z. The subjects evaluate the form-ratios of 3-dimensional cubes and virtual products with SD-scale Kansei words(feelings and images). We applied the factor analysis to identify semantic space in cube model and virtual products. Finally, we compared with kansei structure of cube model and virtual product.

A database was constructed for customers to find and choose and apparel product. The product information was collected from words on several kinds of advertisement, which purchasers meet in their ordinary life. The information was sorted and categorized in 8 basic mother categories (Target group, Color, Apparel type, Fabric, Size, Price, Manufacturer) to build a suitable database structure. Each mother category was arranged into subcategories. Also this study showed a demonstration version of the retrieval system. the research resulted can be used for more intensive retrieval system.

This paper presents a facial expression recognition based on Gabor wavelets that uses a fuzzy C-means(FCM) clustering algorithm and neural network. Features of facial expressions are extracted to two steps. In the first step, Gabor wavelet representation can provide edges extraction of major face components using the average value of the image's 2-D Gabor wavelet coefficient histogram. In the next step, we extract sparse features of facial expressions from the extracted edge information using FCM clustering algorithm. The result of facial expression recognition is compared with dimensional values of internal stated derived from semantic ratings of words related to emotion. The dimensional model can recognize not only six facial expressions related to Ekman's basic emotions, but also expressions of various internal states.

In current study on 8 college students there was examined modulation of eyeblink (as measured by integrated EMG of m.orbicularis oculi) and skin conductance response (SCR) to an acoustic startle probe (85 dB[A] white noise) by attending to task presented in auditory modality (to memorize words for further recognition) and entire performance of the word recognition test. Both eyeblink magnitude and SCR amplitude and rise time to startle probes were modified (larger magnitude of EMG peak, lower amplitude and shorter rise time of SCR) during attending to task as compared to performance on test. Results are interpreted n terms of modification of electrodermal and eyeblink components of startle and orienting reflexes by task characteristics (passive versus active efforts), attentional demands and aversiveness of experimental situation. However, eyeblink startle response manifested potentiation during attending to task, while SCR demonstrated attenuation. There are discussed implications of startle modulatioas a potentially sensitive probe of situational demands in stress research and also are considered prospects for further studies.
