We investigated the RGB and XYZ components of the natural colors (two cherry blossoms, i.e., Someiyoshino and Youkou, and the emission of Heike-firefly), and the physiological effects on Japanese and foreign people were compared. The natural colors were digitally measured as RGB colors, and then they were used as color stimuli. The psychological effects were investigated by administering a questionnaire, which was based on the Semantic differential (SD) method. From the results of the questionnaire, the degrees of expression for the natural colors were quite different between Japanese and foreigners. The kansei on the natural colors between Japanese and foreigners were also different in terms of psychophysical quantity and physical cognition. The results of factor analysis showed that the color of Youkou gave pleasantness to Japanese people, whereas the colors of Someiyoshino and firefly gave pleasantness to foreign people.

By the development of the information-oriented society, it became very easy even for beginners to make collages out of photographs by means of computer software. In old days, those photograph collages could be simply distinguished from true photographs because the photograph collages was made by hand. However, it became very difficult to differentiate the true photograph from the photograph collage by digital Image processing. And then, that kind of collage has many problems concerning copyrights or social ethics etc. On the other hand, the photograph collages seem to be accepted as one of the art technique in the recent photograph world. We show three solutions. First, limit of the copyright use by having All rights reserved or not. Second, the detective technique of an unjust reproduction and modification develops. Third, media literacy education is strengthened.

This study is designed to obtain primary knowledge relevant to impressions on figures, and clarify the effects of color, shape, and location on the impressions on figures by psychology experimentation. A measurement is conducted using the combinations of 3 types of shape, 4 types of color, and 5 types of location. The experimental results show that the most dominant factor that affects the visual impression is the location of a figure, and suggest that the central location is considered well-balanced and favorable. Then, the color is the second most influential factor in the visual impression, and “yellow” yields impressions of gaiety and cuteness, however, “blue” to the contrary yields impressions of gloom and no cuteness. Additionally, the results suggest that the shape is the least influential factor in the visual impression and almost neither types of shape used in this experiment are nice-looking nor cute and have any specific features.

The present paper proposes a real-time rendering method based on object surface properties and multi-spectral reflection model. An RGB image is device-dependent and valid for only the fixed conditions of illumination and viewing. On the other hand, spectral reflectance information of an object surface is more useful than RGB information because we can create realistic images of the object under arbitrary illumination and viewing conditions. Firstly, we develop a 3D reflection model based on Nayer model, Torrance-Sparrow model, Fresnel model and multi-spectral information for precise description of object surface reflectance. Secondly, we develop a rendering algorithm of the object under ambient light source distribution. And also, we implement the reflection model to Graphics Processing Unit(GPU) for improving rendering performance. Finally, we render some objects by using multi-spectral reflection model. The overall feasibility of our method is confirmed based on computer graphics images created by using the estimated parameters.

This study verified how timing of sound effects affects the user's operation performance with interactive content, such as computer games. We conducted an experiment to test the hypotheses that (1) operation performance is slightly degraded if the sound effects lag behind the visual beat with “good” timing and (2) operation performance is substantially degraded if the sound effects lag behind the visual beat with “bad” timing, where the “visual beat” in interactive content is the repetition of periodic visual accents in visual images. Our findings indicate that a delayed timing of sound effects degrades the operation performance, but the degradation depends not only on the degree of delay of the sound effects, but also on how in tune the sound effects are with the visual beat.

In this paper, we carried out a subjective evaluation on the perceptual difference in female speech to show the gender difference in its likability and analyzed a relationship between the acoustic features and subjective scores. This subjective evaluation used female speech uttered by 21 speakers as the stimuli, and 127 subjects (47 males and 80 females) attended it. The results suggested that there was the speech preferred without the gender difference and preferred by one gender. We then analyzed the correlation between subjective scores and five acoustic features: fundamental frequency, formant frequency, amplitude difference, spectral centroid and spectral tilt. In female subjects, statistically significant correlations were observed in all features. In male subjects, significant correlation was observed only in spectral tilt. In particular, correlation in spectral tilt showed the inverse trend between male and female subjects. These results suggest that the spectral tilt is effective in the gender difference.

Healing music and Musicotherapy attract attentions recently. They are beginning to be used in the medical treatment. On the other hand there are little practical utilization to relax with video images compared with music. Visual information is said to occupy about the whole of 80% humans receive from five senses. Therefore it has some potential that visual information affects human's mental and physical state as well as aural information does. This paper attempts to investigate the relation between characteristics of video images and mental relaxation. The one of characteristics we focus is motion speed of video images. It is considered that it might correspond to tempo of music. This paper investigates the relaxation effect by using the index calculated by heart rate variability analysis. The experimental results and analysis confirmed that viewing video images might have higher effect of reducing stress than eyes closed state and the relaxation effect might depend on motion speed.

We produced the average face by combining forty-one facial images of female college students in order to investigate how the facial impression changes depending on distance between eyes and eyebrows. Furthermore, we produced ten experiment samples by shortening or widening distance between them of the average face in five steps respectively. These images were presented individually to ninety college students, and they were asked to evaluate them using twenty adjective pairs. Consequently, the average face received high evaluations about likability-related impressions, while the faces with shorter distance between eyes and eyebrow got high evaluations about activity-related impressions. Moreover, two principal component (“degree of refinement” and “femininity”) were extracted as a result of principal component analysis to evaluation scores. It was found that degree of refinement was likely to be affected by the perceived size of the eyes, and femininity was defined by distance between eyes and eyebrow.

Color has long been considered important by both the manufacturing industry and academia because it affects people’s perceptions, emotions, and behaviors. However, the evaluation of purchasing behavior until now has mainly been only in an experimental environment, and there have been concerns that differed from the actual consumer behavior. Therefore, the causal effect of the strong impression of a manufacturer’s brand color on the purchase behavior in the Japanese automobile industry was verified. Covariate was homogenized by propensity score matching based on the online survey, and the causal effect on purchase intention was extracted. As a result, the impression of the brand color had a positive effect on the purchase intention. This effect was estimated to be 5.739 in odds ratio. Commercial brands, logos, emblems, car body colors, dealers, showrooms, and even professional baseball teams were found to be factors that foster brand color.

The purpose of this study is to examine tightening pressure of the supporter and effect of the elastic property on muscle fatigue through electromyogram measurement. Wearing a magic tape style taping supporter, several healthy students carried out the flexion experiment of the elbow. At this time, the electromyogram of biceps brachii was measured, and MFCV(Muscle Fiber Conduction Velocity) by which, the muscle fatigue index was calculated. As a result, it became clear that the tightening pressure of the supporter which relieves fatigue was 21-28gf/cm2. The elastic property of the supporter which relieved muscle fatigue was almost 0.8kgf/cm as a tension stretch. Local clothes pressure seems to affect that the supporter with the moderate elastic property is fixed in the appropriate tightening pressure in muscle contraction and muscle blood flow. This was assumed to be the reason why muscle fatigue is reduced.

When infants are in their crawling stage, both mothers and infants experience difficulties while changing diapers. We evaluated the effects of pull-up type diaper on physical and psychological burden in comparison to the nappy-type diaper. Twenty-four mother-infant dyads participated in this study. According to the behavioral observation analysis, negative behaviors of mothers and infants while changing pull-up type diapers were significantly lesser than while changing the nappy-type. Pull-up type diapers took mothers 30% lesser time to change, while allowing infants more physical movements than the nappy-type. A spectral analysis of infants' heart rate variability showed that low-high frequency ratio and the change in normalized unit percentage (Nu%) were significantly lower when pull-up type diapers were changed. Negative emotion-related behaviors of both mothers and infants significantly correlated with change in Nu% of infants. Lower physical and psychological burden while changing diapers was associated with pull-up type diapers.

In fashion Business, turnover of stores is decided by the product appeals of fashion apparels and selling capacity of the fashion apparel store. In order to increase the turnover, the selection of apparel goods which are preferred by consumers of the shop is most important. Next, the selling capacity is important. In previous papers, we discussed about the relation between apparel goods and consumers. Fashion apparel is thought to be a carrier of the information which is proposed by the fashion designer. On this account, we assumed the purchase and sale of fashion apparels are the diffusion phenomena of the information in the behavioral space. From the point of view, we propose a mathematical model describing the purchase and sale of the fashion apparels.

In this study, we investigated the relation between autism spectrum tendencies of normal observers and evaluation of facial emotional expressions, used for “Ban Dainagon Emaki”. Recognition of facial expressions was verified by Scheffé’s (Nakaya) paired comparison method using the evaluation attributes of the four emotions (fear, anger, sadness, and happiness) in conjunction with investigation of the Autism-Spectrum Quotient (AQ). Different cognitive patterns especially extracted from communication ability, were confirmed, comparing facial expression recognition tendencies for the two groups, higher levels of autistic - like traits and lower levels of autistic - like traits. Between the two groups, the high levels on the AQ were difficult to recognize the fear of negative emotions, but regarding the happiness of positive emotion, similar tendency was demonstrated. These results are consistent with the findings obtained from previous studies on the tendency of facial expression recognition between healthy individuals and those with traits of ASD.

Nonverbal communications involving physical contact convey “Kansei” information that is difficult to express in verbal communications. In this study, we proposed a method to investigate “Kansei” information in nonverbal communications, and surveyed how people perceive nonverbal communication involving physical contact. In the psychological experiment using questionnaire, we presented various words describing tapping and patting actions with Japanese onomatopoeias and sound symbolic words expressing a concept or nuance that is difficult to verbalize explicitly. Participants first imaged the situation wherein they made communication with another person through the physical contact, and then evaluated the “Kansei” information of communications and rated them by adjectives. We found that onomatopoeias added a variety of impressions to communications with physical contact. We then applied factor analysis using adjective rating to extract a factor space of the communicative actions. For both tapping and patting motion, the first factor represented atmosphere of the behavior, and the second dimension represented activeness of the physical motions themselves. We then mapped the rating scores of desirability of the communication onto the factor spaces. The scores of the first and the second factors well predict in an additive way the desirability of communication for both actions, and the influence of the first factor was stronger than that of the second factor. These results suggest that the structure of factor space represents desirability of the communication regardless of actions. The proposed method may be useful and efficient to investigate the Kansei information, factor space, and their inter-relation, of nonverbal communications.

This study is to induce by the factor analysis the factors of wakuwaku, the positive emotions at work,and to get them structured by the covariance structure analysis. The authors identified five factors composed by twenty-five items as factors of wakuwaku, and then discovered that it is the circulating structure by using the covariance structure analysis. They quantitively validated those factors and its structure by the confirmative factor analysis and the PANAS analysis to prove the efficacy of the structure.

While there are reports on the reliability of the universal goniometer (UG) and smartphone application goniometer (SG), there have been no reports on user impressions when using these devices. In this study, impressions of users of UG and SG that are used in clinical practice were clarified and reliability was compared. Questionnaires on user impressions were administered to 13 staff members who work in the clinical field. Measurements in the hip and knee joints of seven participants were taken by three testers, and intraclass correlation coefficients (ICC) were obtained to assess reliability. Results showed that SG was superior in terms of appearance, weight, texture, portability, usability, versatility and readout. SG was inferior in terms of setting up measurement axes. However, SG demonstrated high reliability even when compared to UG. The intra-and inter-rater ICC were 0.51 to 0.89 and 0.65 to 0.75, respectively.

Emotional state before sleep affects the subsequent sleep onset. The purpose of this study was to investigate how positive/negative emotion before sleep effected hypnagogic state. The movies eliciting positive or negative emotion were presented before sleep. Hypnagogic imagery was recorded as a probe of emotional experience and EEG microstate analysis was used for finding the emotion related EEG activities. The score of emotion ratings for hypnagogic imagery indicated that positive emotion was reported in not only positive condition but also in negative condition. This implied that hypnagogic state might be accompanied by positive emotion. Comparing the appearance of maps obtained from microstate analysis between conditions, the map of right temporal activity was significantly greater in positive condition while the map of the left frontal activity was greater negative condition. These results suggested that the emotion not just in presleep but also in hypnagogic state was involved in sleep onset process.

Using near-infrared spectroscopy, the effect of facial self-touching on the prefrontal cortex activity was investigated by comparing the activations produced by the following conditions: 1) pressure applied to the cheeks (cheek-pressing) with bare hands, 2) cheek-pressing with hands wearing rubber groves, and 3) no touching. The results indicated that regions of the frontopolar cortex (FPC) and orbitofrontal cortex (OFC) were significantly activated only under condition 1 (cheek-pressing with bare hands). In addition, the standard scores (z-scores) for cerebral blood flow in the FPC and OFC were significantly correlated with the subjective scores for pleasant emotions. These results indicate that the FPC and OFC are related to pleasant emotions during self-touching. These findings are expected to be applied to the quantitative assessment of pleasant emotions during facial self-touching.

In this paper, we focus on business and the impedance that is a concept in the electrical engineering. Therefore the purpose of this paper is to provide a new knowledge in this field by using the concept of impedance, and to show the relation of the analogy between the impedance and business, and attractive approach to business, marketing, design, user experience (UX), etc. The meaning of analogy is to guess from those similar. It can be interpreted as one form of analogy, for example, also “parable”. When we have a new experience, we consider the problem by analogy from previous experience unconsciously. This is the basic idea of what we are practicing on a daily life. This concept will be applicable to create a new idea. Rather than bring the near ones, the important thing in analogy conception is that it borrows from a field with distance in contents. Its methodology leads to produce the innovation. If we borrow from a place close that everyone noticed, it is not possible to obtain a value to be expected. Engineering is a discipline that has been developed in the focus be useful to people originally. In addition, its history is old. For example, a core part of the mechanical engineering and electrical engineering is an area that has been established that have something immovable. This field is not an exaggeration to say that to form a “beautiful systematic academism”. Then the primary subject of this paper is to propose the concept of “business impedance”. Originally, both of “business” and “impedance” belong to the field of quite different respectively. Business is in “commercial world”, and the impedance is the field of “engineering”. Impedance is a concept in the electrical resistance of the exchanges in electrical and electronic engineering.

In this paper, the objective assessment scale for Deep KANSEI evoked by high quality sound reproduction was investigated in the following experiments.(1) Subjective evaluation of the quality of musical sound reproduced by two different systems. One was a conventional system and the other was the Extra HI System M which could reproduce superior high quality sound by characteristics of precision wave front and planar wave.(2) Measurement of the nasal skin temperature, which is known to be an index of autonomic nervous system activity. Results showed that a greater pleasant feeling seemed to be evoked in the Extra HI System M condition compared to the condition of the conventional sound reproduction system. The long-term decrease of the nasal skin temperature, which strongly correlates to sympathetic nervous activity, showed a correlation with the subjective evaluation implying the possibility of objective assessment scale for Deep KANSEI.
