Minimalism means abstinence characterized by simplicity, clarity, repetition, and exclusion while skeuomorphism means visual metaphor design characterized by retro, function, and emotion. Mobile platform interface has been developed based on those two aesthetic characteristics and user experience is evaluated using apple iOS6 and iOS7 representing skeuomorphism and minimalism respectively in this paper. Those two aesthetic designs on typography, color, and icon were tested with a sample of 35 undergraduate participants in the repeated measures design and the results showed that participants distinguished two types of aesthetic designs, and evaluated that iOS7 is superior to iOS6 on typography and identity. Comparing the levels of the three variables, aesthetic of typography, and accuracy, aesthetic and consistency of icon design were significantly differentiated and this means that although accuracy of icon design of iOS6 is superior to iOS7, iOS7 is superior in the rest of it. Overall, the participants had a positive evaluation toward iOS7.

The advent of Internet of Things(IoT) has increased the need for development of smart life based on Information and Communication Technology(ICT). By using IoT technology, we are able to control connected appliances using smart devices, such as smart phone. To support the smart life, there is a need to utilize emotion information for human behavior, based on both biorhythm and environment information. Research towards this goal suggests a smart lamp control system that has an effect on the human emotion. According to the PSI theory, the control system calculates the biorhythm with an algorithm that uses the human biorhythm, weather factors and walking amounts. The smart lamp works with the recommended color lights that can control the feelings and emotions of the user. Here, we will show the effect of physical and mental stability, health care, and accident prevention.

Many studies have shown that musical dissonance generally evokes negative affect, but few studies detail how distinct dissonant intervals, ranging in various roughness, influence emotions and cognition. This research entailed two experiments to confirm whether varying musical intervals of dissonance trigger particular negative emotions and increase cognitive interference. Experiment 1 assumed that different dissonant intervals would elicit distinct negative emotions. In a survey involving 131 participants, there was an overwhelming consensus that dissonant intervals elicited stronger high arousal negative affect than low arousal negative affect. The major 7th degree was found to evoke a significantly stronger feeling of scared. Experiment 2 investigated whether emotions-affecting dissonance would have an enhancing effect on cognitive interference. According to a color-word Stroop task conducted on 81 participants, the presence of any dissonant sound caused significantly higher reaction times and error rates than in the absence of sound. In particular, the minor 2nd degree was cognitively the most disruptive and associated with the slowest reaction times. This paper shows how different ranges of dissonance can effectively influence negative affect and heighten cognitive interference.

In the near future, robots should be able to understand human's emotional states and exhibit appropriate behaviors accordingly. In Human-Human Interaction, the 93% consist of the speaker's nonverbal communicative behavior. Bodily movements provide information of the quantity of emotion. Latest personal robots can interact with human using multi-modality such as facial expression, gesture, LED, sound, sensors and so on. However, a posture needs a position and an orientation only and in facial expression or gesture, movements are involved. Verbal, vocal, musical, color expressions need time information. Because synchronization among multi-modalities is a key problem, emotion expression needs a systematic approach. On the other hand, at low intensity of surprise, the face could be expressed but the gesture could not be expressed because a gesture is not linear. It is need to decide the emotional boundaries for effective robot behavior generation and synchronization with another expressible method. If it is so, how can we define emotional boundaries? And how can multi-modality be synchronized each other?

포토닉 의류는 의류에 다양한 광원과 광전달 소재를 적용하여 빛을 발현하는 디지털 기술을 적용하여 의류의 색채를 제어함으로써 착용자의 감성을 시각화할 수 있도록 하는 스마트 의류의 일종이다. 앞서 개발한 포토닉 의류의 중 LED램프와 광섬유의 조합으로 색광을 발현하는 기능은 특별히 RGB 색조합을 통해 의도하는 색채를 다양하게 구현할 수 있다는 특징이 있다. 현재 색채 발현 방법은 Red, Green, Blue의 3가지 색상의 LED의 적절한 조합을 통하여 색채를 발현하는 방식을 가지고 있으나 색체계 상의 기준 색상과 실제 발현되어 육안으로 확인되는 색채의 차이가 있어 의도와는 다른 색채가 나타나 디자이너의 색채 기획의도를 포토닉 의류에 적용하기 힘들며, 기존의 색체계에 의해 생산된 다른 텍스타일 색채와의 컬러 조합에 있어서 필요한 정확한 데이터를 얻기 어렵다. 따라서, 포토닉 의류에 의도하는 색채를 발현하기 위해서는 기존 색상과의 차이점 보정과 효과적인 데이터 베이스 구축이 필요하다. 본 연구에서는 포토닉 의류의 색채에 관한 보다 체계적인 연구를 통해 웹 컬러와 광섬유를 이용한 포토닉 컬러에서의 색채 이미지를 비교, 분석하고 RGB값과 색차값을 통한 차이점 보정을 참고하여 광섬유를 사용하여 제작되는 스마트 포토닉 의류의 제작 시 색채선정 기획에 있어서 기초적인 자료로 활용될 수 있도록 제시하고자 한다.

Although the technology for emotion recognition is important one which demanded in various fields, it still remains as the unsolved problem. Especially, it needs to develop the algorithm based on human facial image. In this paper, we propose the facial image analysis algorithm for emotion recognition. The proposed algorithm is composed as the facial image extraction algorithm and the facial component extraction algorithm. In order to have robust performance under various illumination conditions, the fuzzy color filter is proposed in facial image extraction algorithm. In facial component extraction algorithm, the virtual face model is used to give information for high accuracy analysis. Finally, the simulations are given in order to check and evaluate the performance.

Technologies for video reality (e.g., 3D displays, vibration, surround sound, etc.) utilize various sensory input and many of them are now commercialized. However, when it comes to the use of olfaction for video reality, there has not been much progress in both practical and academic respects. Because olfactory sense is tightly associated with human emotion, proper use of this sense is expected to help to achieve a high degree of video reality. This research tested the effects of a video's color-temperature related scent on reality improvement when the video does not have apparent object (e.g., coffee, flower, etc.) which suggest specific smell. To this end, we had participants to rate 48 scents based on a color-temperature scale of 1,500K (warm)-15,000K (cold) and chose 8 scents (4 warm scents, 4 cold scents) which showed clear correspondence with warm or cold color-temperatures (Expt. 1). And then after applying warm (3,000K), neutral (6,500K), or cold (14,000K) color-temperatures to images or videos, we presented warm or cold scents to participants while they rate reality improvement on a 7-point scale depending on relatedness of scent vs. color-temperature (related, unrelated, neutral) (Expts. 2-3). The results showed that participants experienced greater reality when scent and color-temperature was related than when they were unrelated or neutral. This research has important practical implications in demonstrating the possibility that provision of color-temperature related scent improves video reality even when there are no concrete objects that suggest specific olfactory information.

In film, color is a tool for storytelling and a metaphor for a story's theme. This study constructs efficient and objective data by analyzing color images of movies delivered to the audience. This Research the visual perception process of color in films and studies the processes accepted by the audience. Through this research process, we examine the emotional response caused by the visual stimulus of film color and quantify the visual factor through color in the film as a factor that effectively induces the emotional response of viewers who watch the movie. This study analyzes the mise-en-scene of Wes Anderson's film, Royal Tenenbaum, and studies the role of communication in cinematic colors. Quantitative analysis of color distribution data is performed using computer color analysis program on the colors displayed through 10 chapters of mise en scene. Through color analysis, it was analyzed that Anderson composed the movie scenes in red and yellow red (YR) with low saturation and medium brightness. Through this analysis, we study how color is used throughout the film and how the quantitative form of its use is to be used as the psychological factor controlling audience's emotion.

The article reports findings on: (1) development of emotion assessment scale in evaluating the Television(TV) picture quality; and (2) how psychological and physical factors relate to TV picture quality. A total of 152 adjectives that specifically describe emotional reactions were first selected from a Korean dictionary of adjectives, followed by ratings on their suitability for the evaluation of TV picture quality. The final selection of 19 adjective, based on the reported rating scores greater than 4.1, were used on 126 college students who were asked to perform similarity ratings on the adjectives. Based on factor analyses (i.e., principal component analysis with oblique rotation) on the similarity of scores, the following adjectives were selectively chosen for the development of the new emotion assessment scale: 'neat-messy', 'refreshing-gloomy', 'clean-dirty', 'comfortable-tense', 'smooth-rough', 'bright-dark', 'gorgeous-plain', 'diverse-monotonous', 'satisfying', 'natural', and 'sensuous'. These adjectives composed into two distinct constructs, 'cleanness or smart' factor and 'gorgeousness' factor, which demonstrated sensitivity to changes in brightness, contrast, color, and tint in the TV picture quality, except for changes in sharpness.

The aim of this study was to determine whether or not cardiovascular reactivity parameters serve as good indicators in identifying differential emotion in children. The study particularly focused on five emotions(i.e., happiness, sadness, anger, stress, and boredom), thus, study participants were introduced to a combination of music, color, stories, and dolls to induce complex emotions. During the experiment, corresponding cardiovascular reactivity in response to the conditioned stimuli were recorded on physiological parameters including HR, RSA, HRV, HF HRV, LF HRV, and FPV. After the cardiovascular reactivity responses were measured, participants rated on the types and intensity of emotions they had experienced during the emotional stimuli exposure. Results on psychological response show that four emotions except for stress were appropriately and effectively induced participants by emotional stimuli. Findings of physiological responses suggest that, except for RSA, all of the physiological indicators show significant differences among five emotions. This indicates that children' emotions can be measured and differentiated by cardiovascular reactivity, or in other words, emotion specific responses have the ability to distinguish different emotions in children.
