석현정 ( Hyeon Jeong Suk ),김곡미 ( Gok Mi Kim ) 한국감성과학회 2010 감성과학 Vol.13 No.1

LED technology offers versatile lighting control while having a very low environmental impact. Consequently, increasing attention is being paid to the emotional impact of LED lighting. This study investigated whether the chromacity of LED lighting influences people`s time perception. To this end, two empirical studies were conducted: First, in experiment I(N=28), the subjects compared their perception of the time duration, which was varied from 3s to 20s, for 6 chromatically nuanced lighting conditions, respectively, with that under a daylight condition. The results showed that, in warm-color nuanced lighting conditions, the subjects perceived time to pass more slowly than in the daylight condition. On the contrary, in cool-color nuanced lighting conditions, the subjects perceived time to pass more rapidly than in the daylight condition. Then, in experiment II(N=39), the subjects were asked to count for 90 seconds while simultaneously performing some cognitive tasks. Confirming the results found in experiment I, the subjects perceived time to pass more rapidly in cool-color nuanced lighting conditions than in warm-color nuanced lighting conditions, although the difference was not statistically significant(p>0.05). In addition, the subjects tended to perceive the time to be shorter when the nuanced color of the light was closer to their preferred color.

As the consumer market for odor products grows, companies producing healthcare products are beginning to pay more attention to the emotional aspect of an odor product in order to differentiate their products from competitors. In the following research, the affective effect of odor product was investigated while focusing on relaxation and working contexts using orange and pine scents, since these are typical odors in current domestic market. Two empirical studies were carried out. First, in experiment I, 18 subjects, all of whom were university students, spent 20 minutes sitting comfortably on a sofa while electrocardiogram assessments were made. After a five-minute break, in experiment II, the same subjects were provided with both arithmetic and geometric questions and their electroencephalogram readings was recorded from eight channels. All subjects participated in three sessions - no odor, an orange scent, and then a pine scent - with a minimum time interval of 24 hours. The results show that in the context of a pine scent, both the activation ratio of subjects` parasympathetic system and those of the Sensory Motor Rhythm waves and Mid Beta waves were at the highest peak. Therefore, the pine scent helped the subjects to feel more comfortable and more focused at the same time. In other words, it gave them a state of meditated attention. In addition, it was found that the right brain was activated twice the intensity when the subjects worked through the geometric questions, whereas both sides of the brain were activated in equal magnitude during the process of arithmetic tasks. This replicates previous studies of the functional aspect of the right brain - being responsible for spatial and creative thinking.

Two experiments were carried out in order to investigate the influence of Ring-Back-Tone(RBT) music on the evaluation of the phone-call receiver`s personality in dimensions of Openness, Extroversion, and Neuroticism. In a preliminary experiment, the subjects listened to 17 RBT music stimuli in random order and assessed the personality associated with liking for each music using the 12 personality traits(N=15). Among the 17 RBTs, three were selected to be used in main experiment and they were distinguished from each other in terms of the tree personality dimensions(p<0.001). In main Experiment, it was hypothesized that the evaluation of phone-call receivers` personalities would be influenced by the personality of RBT music. Therefore, in the main experiment, the subjects were divided into four groups and each listened to one of the three RBTs or to a plain ringing tone(control group) until the receiver(the experimenter) answered the call. After interviewing the receiver, subjects evaluated her personality using the 12 traits. The empirical results provide evidence that the RBT influences the judgment of phone-call receiver`s personality in terms of the three personality dimensions(p<0.001), supporting the hypothesis. In addition, it is found that there is a positive correlation between the personalities of RBT music and the phone-call receivers` personalities elaborating the affirmative result for the hypothesis(r=0.753, openness, p<0.01; r=0.753, extroversion, p<0.01; r=0.265, neuroticism).

소비자의 종이색 허용범위에 관한 연구

석현정(Suk Hyeon-Jeong) 한국색채학회 2010 한국색채학회 논문집 Vol.24 No.1

본 연구에서는 소비자가 종이를 구매하고 사용하는 다양한 상황에서 적절한 종이색으로 간주하는 색채 범위를 조사하고자 하였으며, 그 선택의 과정에서 소비자 개인의 친환경 의식이 영향을 미치는가를 파악하고자 하였다. 이에 총 30명으로 구성된 실험참여자들을 대상으로 주광(D65) 환경하에 색채팔레트를 제시한 후, 나열된 266가지 색채 견본에 대하여 종이색으로 허용할 수 있는 종이색의 허용범위를 선택하도록 하였다. 그리고 세 가지 상황적 요인- 구매 혹은 사용을 위한 “목적”인가, 사무용지 혹은 연습장종이의 “용도”인가, 그리고 종이가 재생이 되었는가에 대한 “재생여부”-에 따른 총 여덟 가지(23) 상황에서 실험참여자들의 종이색 허용 범위를 조사하였다. 실험결과, 실험참여자들은 구매보다는 이미 구매된 종이를 사용하는 상황에서, 사무용지의 용도보다는 연습장종이의 경우에, 그리고 종이가 재생된 사실을 인지하는 경우에 종이색의 허용 범위에 있어 관대함을 보였다 (삼원분산분석 결과 0.05 수준에서 유의함). 또한 초록색 계열에서 종이색 허용범위가 가장 넓고, 빨강색 계열과 보라색 계열에서 가장 좁은 것으로 나타났다. 이어서 EAI-24를 활용하여 실험참여자들의 환경보존과 문명이기적 관점에 대한 수준을 수치화하여, 개인의 친환경의식이 종이색의 허용 범위에 끼치는 영향을 분석하였다. 그러나 개인의 친환경 의식과 종이 종이색 허용 범위 간의 유의한 관계를 파악할 수는 없었는데, 이에 대하여 친환경 척도로 활용한 EAI-24의 적절성 및 친환경 의식을 파악하는 방식으로 설문 이외의 정확성이 높은 방법 개발에 대한 필요성을 지적하고 있다. In this study, the consumers" tolerance of accepting colored paper was investigated in order to find out how much influence environmental attitude has on color tolerance. Surveys were conducted that asked about the border colors the participants could tolerate as colors of paper dichotomously varied by three contextual variables, such as intention (purchase versus use), usage (office paper versus notebook paper), and recycled status (not informed versus informed). For color stimuli, 266 samples were collected and displayed in A2 size panel. Based on the participants" assessments, four trends were identified in terms of hue category, intention, usage, and recycled status. For the second part of the study, the participants" environmental attitudes were assessed by facilitating EAI-24. The individual"s attitude toward environment was quantified in aspects of Preservation and Utilization. However, neither qualitative nor quantitative analyses provided any evidence to support our hypothesis that the attitude toward environment would affect consumers" tolerance of paper colors.

Objective: This study proposes a personalized lighting system to enhance the affective quality of passengers" experience in a premium bus. Background: As concerns about user centered aspect increases in public transportation, this study considers passengers" seating postures as the cue to optimally related the behavioral patterns to their desired emotion. Method: Empirical test and user workshop were conducted to explore the personalized lighting in a premium bus. In an empirical test, 34 college students participated and their posture changes were measured with two angle joints- backrest and footrest. Eight types of given activity were narrowed down into four categories, and then during the user workshop, 26 college students explored and assessed the quality of lighting to best enhance affective experience for each of the activity category. Results: We found a noticeable difference across the activity types, and the changes were consistent among the participants in the case of the backrest. In the case of the footrest, however, the representative data were not found as the angle varied a lot individually. Based on the observation we derived four categories of activities: Focus, Casual, Relax, and Sleep. Individual variations were observed as height and sitting habits of participants varied. In total, there are 108 different types of emotional lighting collected, and seven patterns of light distribution were proposed. Conclusion: Passengers are willing to adjust their sitting postures by changing the angles of backrest and footrest, where we can make a good assumption of their desired behavior and emotion based on their postures. Based on empirical studies, we suggest four types of lighting that optimally fits to the frequent activities in a premium bus, such as focus, casual, relax, and sleep. Application: Furthermore, we expect advancement of user-centered lighting design by achieving emotional satisfaction not only in a public transportation but also in any personalized space.

Skin color is a crucial feature for portraits. It has been widely used to enhance portrait quality, but the standard or reference for skin color are quite vague. In this paper, we explore the affective effect of target skin color for image quality. Target skin color are obtained from literature review of three aspacts of skin researches, measured real skin color, memory skin color and preferred digital skin color. According to the evaluation results, we could conclude that different target skin color setting could lead to different emotional image qualities.
