In this paper, we propose a new personalization method for a dialogue system using external knowledge and Graph Convolutional Networks (GCNs). The proposed system is divided into a personalize-part and a response-generation part with Japanese Transformer model. The personalize-part consists of a learned GCN, which can estimate the user’s interests, and a knowledge graph as external knowledge. The personalize-part can add an appropriate template to the response by Transformer according to the dialogue situation and user’s interests. Estimating a topic interesting for each user, the new system can provide an intimate dialogue reflecting individualized interests. We carried out extensive evaluation experiments, and it has shown that the proposed system exceeds the conventional Transformer dialogue model by 35.6% in the variety of information and by 34.0% in the level of desire to use the system.

The relationship between expressions of a class teacher on the class atmosphere was investigated. First, the frequency a teacher showing six basic expressions was assessed. Secondly, the atmosphere of the class was evaluated and factors that composed class atmosphere were subjected to factor analysis, which indicated that class atmosphere consisted of Unity, Friendly, and strict Factors. A model how expressions of a teacher affected the atmosphere of a class was developed using Covariance Structures Analysis (CSA). The results indicated that the expressions of a teacher had a significant effect on class atmosphere.

The purpose of this study is to find effective design elements to make maps easy to use for people with poor directional ability. We conducted comparative experiments using 12 types of existing maps. 58 subjects tried to find their ways using several maps in large spaces such as shopping malls and stations with rather complex structures. After observing their behaviors, we conducted interviews to clarify supportive design elements of maps to find ways. As a result, we found some effective design elements such as vivid color tones, the right angle of bird's-eye-view, the right degree of deformation of illustrations, readable design from upside down position when maps are rotated, for example. We also found two important requirements of map design; (1) landmarks on maps should be easily collated with real landmarks, (2) relations between different stories of the building should be clearly described.

This study investigated the relationship between facial youthfulness and facial areas. The cognitive model reported previously shows that youthfulness is a complex impression composed of estimated age, lively impression, and clean impression. Eight participants rated these impressions of seven facial images using Scheffe’s paired comparison method. The images consisted of an average face of 19 women in their 50s and modified average faces by adding moderate or severe wrinkles on the forehead, under the eyes, or around the mouth of the average face. Additionally, eye-movements were monitored during the rating of the average face. These investigations revealed that youthfulness and estimated age related to forehead and under-eye areas, whereas lively impression and clean impression related to under-eye area. Further analysis suggested that youthfulness had a combined feature of other three impressions. These results support the cognitive model of youthfulness reported previously and demonstrate that important facial areas vary with impressions.

Robot-assisted therapy has gained attention as one of mental health measures. In this paper, we investigated the influences of soft tactility on psychological and physiological stress relief effects to verify whether soft robots or hard robots are effective as therapy robots. Resultantly, we confirmed that psychological stress relief effects obtained by interaction with soft robots are significantly higher than that with hard robots, particularly reducing tension and depression, improving vigor. And we also verified that physiological stress relief effects, especially increasing alpha waves, obtained by interaction with soft robots are significantly higher, too. In addition, we found that soft tactility may have effects of inhibiting reduction users' motivation for interaction. These results suggest that soft robots are more effective as therapy robots.

Humans have various impressions for visual stimulus such as order/disorder and aesthetic preference, but the brain characteristics that each impression reflects are not readily apparent. We hypothesized that perception of order/disorder reflects the stimulus processing fluency. We conducted one preliminary experiment and two main experiments. The preliminary experiment simultaneously presented two stimuli to participants, who judged which stimulus was the more disordered. We scored perception of order/disorder using participants' responses. The main experiments used a same-different judgment task to assess the hypothesis. We presented two stimuli simultaneously, scored with perception of order/disorder. Participants reported whether the stimuli were the same or not. Participants easily judged whether the two stimuli were the same or not when the same-difference task included the stimulus perceived as orderly. Results suggest that the impression of order/disorder reflects the processing fluency for each stimulus.

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.

We discussed how people behave on seeing kawaii animal toys. Many studies have indicated the effects of kawaii emotions. However, few have described how they are expressed behaviorally. Therefore, this paper reports observable behavioral indicators. Specifically, we observed 4 human behaviors: smiling, touching, talking, and watching (kawaii toys or people) - during conversations when they see animal toys. Participants were divided into two groups. One (kawaii group) selected the animal toys that they felt had the most kawaii, and another (non-kawaii group) selected the animal toys that they felt had the least kawaii. Time to behavior was measured by annotation software, analyzed by analysis of variance. Comparison of groups showed that kawaii group was smiling, talking, and watching people for a longer time. Conversely, non-kawaii group was watching animal toys for a longer time. These results deepened our understanding of human behavior caused by kawaii emotion.

Under difficult COVID-19 situations, restricted movements and increasing stress demand casual counseling. Counseling in a virtual space would lower the psychological barrier to consultation by concealing the client and the counselor’s figure. This study examines whether the willingness to consult would change by the seriousness of consultation and the different appearances of the counselor’s avatar. As a result, in the serious consultation situation, the willingness to consult with the avatar in a white coat was high. In the informal consultation situation, the willingness to consult with the avatar wearing a hood was high. Furthermore, with eye-tracking, we found that people’s attentive areas were different by the situation and by the appearance of the avatar. These results suggest the potential for the avatar counseling system in the Metaverse and remote virtual reality (VR) counseling.

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.

It is difficult to find out what consumers actually demand, in a society with various information and products. Under such circumstances, the importance of finding consumer insight is increasing. However, it is difficult to find out consumer insight. In this paper, the effect of using visuals for the discovery of consumer insight was verified compared with using text. The experiment was conducted with two groups. Each group came up with ideas on two themes. At that time, the following conditions were set: one is to use visuals and the other is to use text. Then, the contents were analyzed using Finke’s Geneplopre model. The result showed that, the number of ideas with visuals were fewer than the number of ideas with text. However, it was implied that using visuals allows for deeper and wider interpretation of ideas, which could lead us closer to true consumer insight.

This paper proposes a method to detect attractive phrases from musical lyrics. The method considers not only acoustic but also lyrical features which attract human attention. Through the interview on impression for lyrics, we have found that “uniqueness of co-occurred terms” and “repetition” significantly influence human attraction. Therefore, we modeled these linguistic expressions as mathematical features. The proposed method detected attractive phrases using support vector machine with the modeled features. The results of the model evaluation experiments showed the 69% accuracy and 86% precision. Moreover, the results were compared and discussed with the key sentences detected by the existing summarization methods. As the result of comparison, it is confirmed that the proposed method detected attractive phrases more accurate than the existing summarization methods.

Short-pause is one of the important elements of presentation. In this study, we have investigated differences of taking short-pauses between winners and losers of book review presentation game, Bibliobattle. In order to find short-pauses, non-utterance sections in presentations are detected by converting time discrete audio signal to energy. Length, times and appearance position of short-pauses of winners and losers were compared. As a result, the following things were revealed. The first is that the average times of winners' brief (less than 0.4 sec) short-pauses is significantly smaller than losers' one. The second is that the losers' average times of short-pauses which appeared in unnatural position (between noun and postpositional particle or suffix) is significantly larger than winners' one.

Onomatopoeia refers to words that represent the sound, appearance, or voice of things, which makes it possible to create expressions that bring a scene to life in a subtle fashion. In this paper, we propose an onomatopoeia thesaurus map to enable the construction of a map that visually confirms “similarity relationships between a number of onomatopoetic words” and “similarity relationships between unknown onomatopoetic words and existing onomatopoetic words,” which are difficult to grasp from a conventional thesaurus. It is also possible to label objects with onomatopoetic words and visualize the similarity relationships between the objects on a map. In this paper, we introduce an example of labeling onomatopoetic words relating to the textures of sweets (desserts).

In this paper, we propose a font automatic generating system considering quality of a generated font. This system learns a placement of skeleton points in a font to evaluate shape of the font by GRNN (General Regression Neural Network) for each element. Furthermore, using the shape evaluation by the GRNN, the proposed system generates a font considering the quality by revising placement of skeleton points and transformation parameters of the font. In addition, to learn the shape evaluation of the font, a user can evaluate the generated font interactively on the Web. The proposed system has the following three advantages. First, it is possible to evaluate a shape itself of the font. Second, it is possible to make a modification automatically for a skeleton and transformation parameters of a font by shape evaluation. Finally, an interactive shape evaluation of a generated font is possible with low burden.

In human face-to-face communication, not only verbal messages but also non-verbal behaviors such as facial expressions, body movements, and gazes are conveyed; these non-verbal behaviors can express human affect. In addition, it leads to sharing of empathy unconsciously in human interaction and enhancing intimacy between humans. In particular, cognitive empathy as well as emotional empathy play an important role in sharing of empathy. Therefore, it is expected to evaluate emotional empathy based on the features of affect for enhancing intimacy. In this study, for the basic research of evaluating emotional empathy, a method that estimates the emotional centroid based on the coordinate system in the Russell’s circumplex model was proposed. In addition, the experiment was conducted to evaluate the proposed method. The results demonstrated that the method has a possibility to estimate the features of affect.

The objectives of this research are to implement the examination and the analysis of the utterances that accompany movements, and to elucidate whether these utterances are likely to be applied as movement-support technology. In the first phase of the field survey, we studied changes in the rate of vocal output with changes in the height of a platform to stand on; then, in the second phase of the survey, we investigated the influence exerted by vocal output or the absence thereof on walking ease and Maximum Walking Speed (MWS). In the analytical study, we observed excitation levels of spinal motor cells in healthy adults using H-wave. It is suggested by the results that (1) the rate of vocalization changes, (2) MWS is not improved, (3) the ease of walking is affected, and (4) the level of stimulation of spinal cord motor cells is increased.

Because the color of lipstick is important for total fashion image, we tried to analyze the characteristics of colors of lipsticks of popular brands especially for Japanese female students. Preparing a database consists of 294 color images obtained from websites of lipsticks, we performed statistical analyses such as distribution chart and decision tree for their RGB values. The analysis results show that “MAC has relatively different RGB values from other brands,” “The products with high R values tend to be CHANEL,” and some similarities between brands. Those successfully gave the subjective evidences for the empirical knowledge of the fashion expert.

Emojis are extensively used to convey emotional nuances non-verbally in computer-mediated communication. Previous studies have examined how emojis are used and how they change the expression of a sentence, as well as the subsequent impression of the reader. Regarding whether the writer’s emotion is understood correctly by readers, evidence shows that emojis can enhance specific emotions. However, the effects of variation in the kinds of sentence, emotion, and emoji on the shifting emotion conveyed have not been studied. In this study, we examined the various factors that affect the shift in emotions being communicated. Our results demonstrated that positive emotions can be communicated more correctly compared with negative emotions and that smiley emojis (a.k.a. emoticons) can communicate emotions more clearly compared with other kinds of emoji.

The main purpose of this paper is to develop an easy-to-use smartphone case with “fall prevention function”. It shows as a remarkable point that our developed technique of determining the grip form reflecting the traditional craftsmanship verifies for the made-to-order wooden products. It also provides the experimental result of wooden smartphone case using electromyography (EMG). The experiment consists of two cases, with using a smart phone case and not it. Then, it compared with these two cases, the result of measuring the amplitude of gripping forces. The experiment suggests that using the smartphone case relatively clearly that applies significantly less gripping force, so that prevents dropping a smartphone. The experiment suggests that using the smartphone case it applies significantly less gripping force. It will provide a new guideline of the universal design as a case study of Kansei/affective engineering regarding human grip.
