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.

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.

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.

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, 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.

The objective of our studies is the inquiry into data set of the silhouette styling by machine learning for the luxury brands. The computer vision meets the visual fashion for the long years. Recently, computer vision techniques has been employed in algorithm of fashion recognition. But the aim of the computer vision is that the computer vision meets fashion but not that fashion meets computer visions. The luxury fashion consumer expects the favorite own beautiful silhouette styling, not simply the computer pictures. Therefore, silhouette learning of clothing by Neural Network Console needs to meet the personal professional styling knowledge.

In order to design suitable clothes for elderly women, we surveyed the body image consciousness, types of clothes that were purchased frequently, and clothing fit preference in women aged 60-89 years by questionnaire, and analysed the results by age group. When asked about their body image, more than half of them did not acknowledge any increase in bending of the back despite getting older. Recently purchasing and frequently wearing clothes is such as shirts and pants. However, this study revealed that they do not often purchase or wear skirts or dresses. Their preference when purchasing clothes is to highly value items that “suit their somatotype”, “comfortable” are appealing. Meanwhile, as a result of Primary Component Analysis in each age group, “functional clothing that emphasizes auxiliary life activities” in the first principal component shows a high amount of factor loading.

Tools are indispensable for our daily life. For example, we use knives to process foods or other materials such as resin or wood. Tactile texture sensation which arises when we touch objects directly has been investigated by many groups. However, the sensation caused by the use of tools has not well been explored. In this study, we focused on kitchen knife which we often use for cooking, and evaluated sensation caused by the use of the kitchen knife. In the experiment, we asked 20 participants to cut 12 foods and rate the sensation of each item. Furthermore, we measured force and acceleration to analyze the relationship between sensation and these physical quantities. The result showed that sensation via cutting process can consist of three sensory factors, “ease of cutting”, “density”, and “elasticity”, and these sensory factors relate to the physical quantities.

The purpose of this study is to clarify the mechanism of smiles by measuring facial muscle activities and facial surface transformation. We made it possible that the strength of the smile was fixed the same by using the biofeedback technique. And facial muscle activities that caused a change on skin surface were measured by surface electromyography and the physiological mechanism of the smile was examined. It became clear that the muscle activities of the risorius and depressor labii inferioris had a significant effect on the formation of the smiling faces. We confirmed that a change of the eye that is the symbol of the smile depended on the compression of the skin by the picture analysis of the face. The internal and external relations to make the characteristics of the smile were explained.

In this paper, we investigated how readers perceive the emotions of writers based on the emoticons in their tweets, and clarified the influence of emoticons on emotions. Initially, we conducted a questionnaire and the emotions associated with tweets (with and without emoticons) and the emotions associated with the emoticons were quantified. Multiple regression analysis was then applied to three types of emotion data, and relationships among them were established in the form of regression equations. Finally, the accuracy of the regression equations was estimated for learned and unlearned data, and their effectiveness and robustness were evaluated. The following 10 types of basic emotions were utilized as targets: “Sadness,” “Dislike,” “Relief,” “Fear,” “Excitement,” “Liking,” “Joy,” “Surprise,” “Anger,” and “Shame.”

Mizuhiki is a decorative Japanese cord and used for gift-money envelopes. This study shows our investigation results regarding impressions given by Mizuhiki. The advantages are the clarification for impression structure, the use of an analysis method focusing on two factors, and the development of an interactive visualization tool. First, we got five factors from factor analysis. The factors are gorgeousness, grace, favorability, novelty, and loveliness. We analyzed the relationships between two factors using a robust PCA, thereby we could know some effect factors for increasing or decreasing the impressions belonging to two factors. In addition, we developed a new visualization tool for impressions of Mizuhiki and confirmed the effectiveness via users’ experiments.

Reading is human intellectual activity itself. Therefore, there have been many discussions to clarify this principle for a long time. In recent years, with the advent of electronic books (e-books), which are highly functional books, reading has become more enriching. However, it is less clear what affect this new way of reading is having on the reader. In this regard, we aim to clarify the effects of social reading, the reading of sharing with others using features specific to e-books. We focused on the sharing of reviews, which is common in social reading, and used an experimental system to analyze latent factors and satisfaction. As a result, we found two factors and three clusters constituting potential factors, and four quadrants and three clusters constituting satisfaction.

When we play three-dimensional computer graphics (3DCG) video games of third-person point of view, we can usually control both an avatar and a camera. There are some enemy characters in the CG game world, and we often lose contact with an enemy after the avatar collides with it. In this paper, we propose a camera control system that the view point makes a half turn in a horizontal direction after the avatar collides with the enemy. The camera shows both of the avatar and the enemy from the backside of the avatar. In addition, we propose a representation technique that obstacles make translucent to avoid occlusion when the avatar collides with the enemy. As a result of subjective evaluation experiment, it was shown that the visual effects of the proposed techniques useful to enhance affective impressions. Therefore, we think that the proposed techniques contribute to qualities of action video games.

To improve the safety of autonomous cars, their obstacle detection capability in bad weather must be substantially improved. Haze is a major factor that degrades outdoor images. Although various dehazing schemes have been proposed, a dehazing scheme designed to improve obstacle detection capability has not been reported. Hence, we present a dehazing algorithm that enhances the safety of an autonomous car. This algorithm should be able to work in real time, even using edge computers typically installed as car electronics. Furthermore, this algorithm should work on grayscale images, as systems dependent on color images are often unaffected by environmental color changes caused by factors such as a setting sun. The empirical results showed that our grayscale image-based proposed algorithm is comparable to the results of current cutting-edge methods, and operates in real time.
