  • The aim of this study is to determine the effect of motion sickness on pupil rhythm. Sixteen volunteers of both genders (8 male, 8 female, mean age $25.67{\pm}2.43$ years) experienced VR contents in both 2D and HMD versions for 15 minutes, and their pupillary rhythms were compared. The irregular pattern of the pupillary rhythms, as demonstrated by increasing mean pupil diameter (mPD) and standard deviation of the pupil diameter (sPD), revealed motion sickness after experiencing HMD condition. The pupillary response is strongly related to the cognitive load, and the motion sickness can be interpreted as a change in the cognitive load caused by the increasing volume of visual information that must be processed and the conflict or inconsistency between different sensory modalities. The method proposed in this study could be a non-contact measurement method for the monitoring of motion sickness using a web-camera rather than previous sensor-based methods.

  • The purpose of this study was to investigate the effect of contact type textile electrode structure on heart activity signal acquisition for smart healthcare. In this study, we devised six contact type textile electrodes whose electrode size and configuration were manipulated for measuring heart activity signals using computerized embroidery. We detected heart activity signals using a modified lead II and by attaching each textile electrode to the chest band in four healthy male subjects in a standing static posture. We measured the signals four times repeatedly for all types of electrodes. The heart activity signals were sampled at 1 kHz using a BIOPAC ECG100, and the detected original signals were filtered through a band-pass filter. To compare the performance of heart activity signal acquisition among the different structures of the textile electrodes, we conducted a qualitative analysis using signal waveform and size as parameters. In addition, we performed a quantitative analysis by calculating signal power ratio (SPR) of the heart activity signals obtained through each electrode. We analyzed differences in the performance of heart activity signal acquisition of the six electrodes by performing difference and post-hoc tests using nonparametric statistic methods on the calculated SPR. The results showed a significant difference both in terms of qualitative and quantitative aspects of heart activity signals among the tested contact type textile electrodes. Regarding the configurations of the contact type textile electrodes, the three-dimensionally inflated electrode (3DIE) was found to obtain better quality signals than the flat electrode. However, regarding the electrode size, no significant difference was found in performance of heart signal acquisition for the three electrode sizes. These results suggest that the configuration method (flat/3DIE), which is one of the two requirements of a contact type textile electrode structure for heart activity signal acquisition, has a critical effect on the performance of heart activity signal acquisition for wearable healthcare. Based on the results of this study, we plan to develop a smart clothing technology that can monitor high-quality heart activity without time and space constraints by implementing a clothing platform integrated with the textile electrode and developing a performance improvement plan.

  • The purpose of this research was to determine whether multimodal cues in an online shopping environment could enhance tactile consumer mental imagery, purchase intentions, and attitudes towards an apparel product. One limitation of online retail is that consumers are unable to physically touch the items. However, as tactile information plays an important role in consumer decisions especially for apparel products, this study investigated the effects of multimodal cues on overcoming the lack of tactile stimuli. In experiment 1, to explore the product, the participants were randomly assigned to four conditions; picture only, video without sound, video with corresponding sound, and video with discordant sound; after which tactile mental imagery vividness, ease of imagination, attitude, and purchase intentions were measured. It was found that the video with discordant sound had the lowest average scores of all dependent variables. A within-participants design was used in experiment 2, in which all participants explored the same product in the four conditions in a random order. They were told that they were visiting four different brands on a price comparison web site. After the same variables as in experiment 1, including the need for touch, were measured, the repeated measures ANCOVA results revealed that compared to the other conditions, the video with the corresponding sound significantly enhanced tactile mental imagery vividness, attitude, and purchase intentions. However, the discordant condition had significantly lower attitudes and purchase intentions. The dual mediation analysis also revealed that the multimodal cue conditions significantly predicted attitudes and purchase intentions by sequentially mediating the imagery vividness and ease of imagination. In sum, vivid tactile mental imagery triggered using audio-visual stimuli could have a positive effect on consumer decision making by making it easier to imagine a situation where consumers could touch and use the product.

  • EEG has been used to measure the emotion of amenity and discomfort in the interior space. EEG is limited to the experiment, because it is a equipment of contact type. However, Vibraimage can measure the emotion with a web camera. Because Vibraimage is a equipment of non-contact type, it is more suitable for the interior space than EEG. Therefor, it tries to find a correlation variable between EEG and Vibraimage to measure the human emotions. In this study, it were analyzed correlation of EEG and vibraimage due to variation of loudness 60[dB], 90[dB] and rosemary, jasmine scents. Check the health status of subjects who were selected 3 male students, and the period of this experiment was about months. The condition of the environmental test room was in temperature 25[$^{\circ}C$], relative humidity 50[RH%], air current speed 0.02[m/s] and illuminance 1000[lux]. It were analyzed correlation of twenty-three index of EEG(absolute ${\theta}$, relative ${\theta}$, absolute $S{\alpha}$, relative $S{\alpha}$, absolute ${\alpha}$, relative ${\alpha}$, absolute ${\beta}$, relative ${\beta}$, absolute $\gamma$, relative $\gamma$, absolute $F{\alpha}$, relative $F{\alpha}$, absolute SMR, relative SMR, $SMR/{\theta}$, $SMR+M{\beta}/{\theta}$, absolute $H{\beta}$, relative $H{\beta}$, $H{\beta}/{\alpha}$, absolute $M{\beta}$, relative $M{\beta}$, SEF50, ASEF50) and ten index of Vibraimage(Aggression, Stress, Tension/Anxiety, Suspect, Balance, Charm, Energy, Self regulation, Inhibition, Neuroticism). As a result, I was found that relative ${\gamma}$ index of EEG and neuroticism index of Vibraimage have a high correlation as (${\pm}$).414 and (${\pm}$).424.

  • In this study, we propose a signal processing algorithm to measure the arousal level of a human subject using a PPG(Photoplethysmography) sensor. From the measured PPG signals, the arousal level is determined by PPI(Pulse to Pulse Interval) and discrete-time signal processing. We ran psychophysical experiments displaying visual stimuli on TV display while measuring PPG signal from a finger, where the nature landscape scenes were used for restorative effect, and the urban environments were used to stimulate the stress. However, the measured PPG signals may include noise due to subject movement and measurement error, which results in incorrect detections. In this paper, to mitigate the noise impact on stimulus detection, we propose a detecting algorithm using digital signal processing methods and statistics of measured signals. A filter is adopted to remove a high frequency noise and adaptively designed taking into account the statistics of the measured PPG signals. Moreover we employ a hysteresis method to reduce the distortion of PPI in decision of emotional. Via experiment, we show that the proposed scheme reduces signal noise and improves stimulus detection.

  • 오늘날 화장품 산업은 역동적으로 끊임없이 변화하고 있다. 화장품은 한 사회 구성원들의 다양한 욕구, 가치관 및 생할양식에 영향을 미치며 심지어는 국가의 정치적 기후나 경제적인 상태를 나타내는 지표역할을 담당하기도 한다. 즉, 화장품 과학은 예방의학, 건강과학이라는 차원에서 뿐만 아니라 미적인 차원에서 새로운 상품개발이 진행되어갈 것이다. 지금 우리는 21세기를 향하여 1990년대의 중반기에 들어섰다. 80년대는 물질 문명의 중심으로 생활의 질의 풍요로움을 추구하였으나 90년대는 소비자 우선의 풍요로움을 향수하는 시대가 되었다. 또한 여성이 사회진출, 고령화의 급속한 진전, 고 학력화, 개인의 가치관 존중 및 많은 생활패턴의 변화가 마음의 풍요로움을 구하는 사람들이 늘어나고 물질적 의존도로 부터의 탈피가 크게 강조되고 있다. 이에 마음의 풍요로움을 창조하여 연출하는 화장품산업의 역할이 고기능성에 의한 부가가치를 높이고 마음의 풍요로움을 지원하기 위한 연구개발에 중점을 두고 진행되어 가고 있다. 화장품을 여성들의 치장이라고 하는 주체적 행위에 도움을 주는 하드웨어라고 한다면 소비자의 마음은 소프트웨어로써 소비자 입장에서 만족할 수 있는 전략을 구사하는 아이디어가 있어야 하는데 그에 상응하는 대책으로 스킨케어를 들 수 있다. 스킨케어란 병든 피부를 제외한 여러 가지 유형의 피부를 화장품과 미용기기를 이용하여 그에 맞게 예방관리 하여 건강하고 아름답게 보호 유지하는 전문 분야이다. 즉, 스킨케어는 화장품 이용을 통하여 미래의 소비자들의 다양한 비용 욕구 및 소망에 효과적으로 대응할 수 있는 소프트웨어라고 할 수 있다., 또한 스킨케어는 화장품 뿐만 아니라 신체적 접촉을 통하여 안위를 제공하는 수단으로 단순한 피부손질이라는 문제에 그치지 않고 접촉을 통해 마음과 신체의 균형을 꾀하는 생명현상의 심층과 연관되는 중요한 의미가 있다. 스킨케어는 불어로 Soin Esthetique 라고 하는데 어원을 보면 손질, 처치, 보살핌 그리고 배려를 의미한다. 지금으로부터 200년전 독일의 미학자인 Baumgarten이 미는 인간에게 만족과 쾌감을 주는 대상이며 미는 보는 사람의 마음에 있다라는 감성의 미학에서 Esthetique라는 단어를 처음 사용했다. 다시 말하면 Soim Esthetique는 인간의 마음 만족과 쾌감을 주는 배려 있는 조치로써 여성이 화장을 함으로써 외모의 조화에서 마음과 신체의 균형을 꾀하는 생명현상의 심층과 연관되는 것과 마찬가지로 에스테틱과 화장의 심리는 매우 땔래야 땔 수 없는 불과분의 밀접한 관계라 볼 수 있다.

  • In the case of long-term hospitalization for young patients, 'Hospital Schools' are operated to pursue school classes and to develop social and emotional abilities for them. However, face-to-face classes at hospital schools have been completely prohibited, and the untact or limited contact environment has been strengthened even for young patients due to the COVID-19 in recent years. Augmented Reality(AR) technology enables the development of experiential content with virtual environments, objects and characters similar to real life. The developed contents should revitalize the imagination of young patients living only in hospitals and allow them to experience, not only acquiring knowledge, but also improving interpersonal skills and sociality. This study is intended to provide diverse adventures and in-depth choice experiences to young patients who are struggling in an environment of untact and limited contact by creating experiential fairy tale contents using AR technology. In addition, long-term hospitalized children will be able to cultivate the will to overcome illness with positive emotions through the augmented reality experience fairy tale content studied and implemented in this study.
