Utilization of teamwork for problem solving is pervasive. Teamwork is employed in classrooms to facilitate learning, but also as preparation for future vocational practice. It is used in research as collaborative ethos. Teamwork features in workplace tasks, leisure time projects, pursuing solutions to intractable trans-situated problems, etc. The space of teamwork is a public space of multidimensional assets. Inherent in it are benefits of collaboration, but it also brings with it challenges that have to be resolved in order for it to work effectively. We pursue the question of effectiveness of team function through team size, given certain identified benefits and disbenefits. We attempt to find out if there is an optimal small team size based on a few characteristics such as burden sharing, transactive knowledge and conflict (e.g. schedule conflict). We employ an agent-based model. For parameterization of variables, we take data from a short questionnaire completed by students and use its results to set values. We create small teams of different sizes and allow the dynamic model to aggregate those values as adopted by agents. We also attempt to see which one of four benefit/disbenefit valuation model specifications might work best.

Although mental disorders have emerged as serious social challenges, social stigma, including prejudice and misunderstanding, hinder suitable treatment for the patients. It is crucial to monitor our internal psychological and emotional states to avoid the unconscious progression of mental disorders. This research aims to achieve emotion-reacting garments and accessories, based on a passive and continuous emotion recognition system in real time. First, this study proposes a systematic design for emotion-reacting garments and accessories, which employs emotion estimation based on facial expressions. Next, emotion-reacting fashion design is discussed for intelligent garments and accessories that interact with our bodies and mind. To achieve this system, a functionally extended collar made of transparent polycarbonate material is designed for integration with the digital camera modules. In addition, this study discusses how to create a physical stimulus on emotion-reacting garments and accessories. The intelligent garments and accessories using RGB-LEDs create visual effects that reflect emotions. In terms of audio effects, emotion-related keywords are employed to select the music played in intelligent garments. Finally, prototypes reacting to emotions are shown

The evaluation of physical attractiveness has been reported to be related to the psychological process for detecting associated physiological health and fertility features. The femininity of the female gait is also associated with its attractiveness. However, it is unclear whether femininity is always attractive in female gait and what physical characteristics are perceived as being attractive and/or feminine. In this study, we aimed to understand the root of the attractiveness of human movement by examining the relationship between perceived attractiveness and femininity in female gait. First, we created 30 s gait animations by using 3D motion capture data of 10 female nonmodels and seven female runway models, where they walked either barefoot or in high heels. Then, 60 observers evaluated the attractiveness and femininity of each animation. We compared the scores of attractiveness (A-scores) and femininity (F-scores) of the models and nonmodels, and we examined the factors related to the evaluation (A-scores and F-scores), namely, the walkers’ height, weight, BMI, and the characteristics of movements. Consequently, both the A-score and the F-score were high for the models’ gait in high heels. Conversely, in the other conditions, there were two types of attractiveness−femininity relationships—a linear relationship (high A-score and F-score, or low A-score and F-score) and an unequal relationship (high F-score but low A-score). Most physical and motion factors correlated with both the A-score and the F-score; however, BMI, flexibility at the thoracolumbar joint, stride time CV, and toe-off angle were related to either the A-score or the F-score.

In recent years, due to the active development of cultural and creative industries in Taiwan, cultural elements in exhibitions are often used in product design. Generally speaking, cultural and creative design elements exist in ordinary life and can be found in specific life. Although Tainan Art Museum in Taiwan aims to promote local art, it introduces a special exhibition of Japanese contemporary artist Yoshitomo Nara for the purpose of promoting modern art. Taking this special exhibition as a case, this research aims to analyze the attractiveness of the commodities in transnational exhibitions and discuss the essential spirit of the intercultural commodities. The research results put forward four attractiveness, that are practical feeling, satisfied feeling, mysterious feeling and unique feeling, for the formation of museum cultural commodities, can be used as a reference for the future product development and selection of art museums.

We investigated the effect of men’s dress shirts on impressions of wearers’ motivation and performance in the workplace, and appearance. A ready-made commercial shirt was used as a reference. Four types of shirts associated with high status (a high-priced ready-made shirt, a custom-made shirt, a high-end brand shirt, and a luxury brand shirt) were presented either alone or with neckties, on identical mannequins. Fifty-one Japanese university students in their 20s and 85 office workers in their 20s to 60s evaluated their impressions of the shirts. We provided no information about the shirts. Compared with the standard shirt, the evaluations of some shirts associated with high status were higher in both groups of participants. However, the presence of wrinkles was associated with lower evaluations, even for luxury brand shirts. Wearing a necktie improved participants’ evaluation of appearance and impression for all shirts. Overall, the results revealed that dress shirts affected participants’ impression of wearers’ motivation and performance.

Human needs shift from material to mental with time. And the final need is Self-Actualization. In other words, our needs shifts from product to process. We actualize ourselves to satisfy our emotions. Emotions are interpreted as our feelings toward outside stimuli. But as the fact that etymologies of emotion and motivation come from the same Latin “movere” indicates, emotion means that we are stimulated and motivated by the environment and situation, so that we “move out” into the Real World to establish our own world. It is said that only humans can think about the future. That created “Engineering” to make our dreams come true. As our needs started from material, we eventually looked for better products and for better technologies. And it brought the Industrial Revolution. But the Industrial Society is getting to its ceiling and we need to explore a new society which is emotion-focused. Another important point which we discuss here is the importance of body movement. Although DX is getting wide attention these days, Analog plays an important role in the Real World. Blood is analog and it carries signals and keeps our body organ running after brain death. And Blood and Body Movement plays a crucial role in arousing emotion. When our heart leaps up, our blood boils. And the idea of weight, length are based on our deep sensation of our body movement. This paper discusses how emotion and body movement are deeply associated.

The aim of this paper was to systematically explore the knowledge landscape of papers presented at KEER conferences over the last decade. We collected all papers published in conference proceedings between 2010 and 2020. We (i) used a text mining pipeline to extract, clean, and normalize keywords from the Title and Abstract fields, and (ii) created a co-occurrence network reflecting the relationships between keywords. The network was then characterized at different levels of granularity (static analysis vs. time slice analysis and whole network vs. node-level analysis). The exploratory analysis showed a stable expansion of the network over time. The cluster structure revealed several groups of keywords that did not change over time and reflected both domain-specific and method-specific topics of research in Kansei engineering.

Indonesian design practitioners have shown interest in adapting the established cute visual culture, commonly used in Japan, to improve public service communication. This assimilation effort may enhance communication effectiveness; however, previous research has shown that cultural factors can harm communication effectiveness. We conducted this study to determine if and which public service poster impressions are affected by cultural factors. We compare impressions of Japanese and Indonesian subjects when looking at selected manner awareness posters. We measure the intensity of impressions with an online survey method. Participants had to score the poster images based on ten impressions previously selected through a preliminary experiment and translation check process. Fifty-nine Japanese (n = 29) and Indonesian (n = 30) adults participated in the survey. Impressions with major effect were realness and casualness, while Impressions with a slight effect were reassurance, playfulness, imaginativeness, importance, preference, and sharing intention. Finally, we found that the impression of cuteness and picture-text orientation were least affected by cultural factors. We conclude that cognitively evaluated impressions, such as reassurance, realness, and casualness, appear more affected by cultural factors than cuteness. We confirm the universality of cuteness impression, which we may adapt for visual communication across different cultures.

Mouthwash prevents bad breath and sterilizes bacteria that cause dental caries and periodontal disease, so it provides important means for improving oral hygiene in our daily life. Along with active ingredients such as bactericides, mouthwash contains a variety of aromas to mask the bitterness of base ingredients and increase palatability. However, given that numerous aroma studies have demonstrated various physiological efficacies of aromas on autonomic/central nervous systems, it is no wonder that aroma mouthwash has some sort of physiological impact when it is used. In this study, we investigated the effect of aroma in mouthwash on peripheral and cardiac autonomic nervous system activity. The experiment was carried out in a within-subject design wherein 20 healthy women under 5 conditions, which are 4 types of mouthwashes: peppermint, peppermint + bergamot, peppermint + orange, and peppermint + lavender, and water as a control. Participants performed a 20-minute calculation task as a cognitive stressor, and then rinsing by a mouthwash or water. We evaluated the recovery period from acute stress response for 20 minutes after the task. As a result, it was observed that a mouthwash with citrus flavor had a relaxing effect in terms of subjective scores and recovering from physiological stress response. The results may illustrate a potential benefit of using aroma mouthwash.

Applications operated on smartphones and other devices with a small user interface area on the screen and a large number of functions and contents will inevitably increase the number of operation procedures and make them more complicated. However, compared to the attention paid to information architecture and interaction in realizing intuitive user interfaces, less attention is paid to icons, and there are many examples where generic icons are used. Therefore, when icons and the functions they represent are different for each application, or when icons are unintelligible because of the distance between the user's mental model and the icons, the cognitive burden on the user is amplified, which may affect usability. We compared the usability of icons, one of the GUI elements, by focusing on their metaphors, and showed that the selection of metaphors that are in line with users' mental models has a positive effect on usability by improving the performance of task completion time and the number of errors. This study clarified the influence of the degree of congruence between the metaphor used and the user's mental model on the usability of icons, one of the GUI elements.

However, compared to the attention paid to information architecture and interaction in realizing intuitive user interfaces, less attention is paid to icons, and there are many examples where generic icons are used. Therefore, when icons and the functions they represent are different for each application, or when icons are unintelligible because of the distance between the user's mental model and the icons, the cognitive burden on the user is amplified, which may affect usability. We compared the usability of icons, one of the GUI elements, by focusing on their metaphors, and showed that the selection of metaphors that are in line with users' mental models has a positive effect on usability by improving the performance of task completion time and the number of errors. This study clarified the influence of the degree of congruence between the metaphor used and the user's mental model on the usability of icons, one of the GUI elements.","PeriodicalId":433529,"journal":{"name":"9th International Conference on Kansei Engineering and Emotion Research.
